emulsified asphalt equipment

The surface tension of asphalt and water varies greatly, and asphalt and water will not mix at room temperature or high temperatures. However, when the emulsified asphalt is subjected to high-speed mechanical centrifugation, shearing, and impact, it forms particles with a size of 0.1-5 microns and disperses them into a water medium containing a surfactant (emulsifier stabilizer). Because the emulsifier adsorbs on the surface of the emulsified asphalt particles, it reduces the interfacial tension between water and asphalt, allowing the asphalt particles to be dispersed in the surfactant-containing water medium (forming a stable dispersion in the water). Emulsified asphalt equipment produces an oil-in-water emulsion. The dispersion is brown, with asphalt as the dispersed phase and water as the continuous phase, and has good fluidity at room temperature.
Precautions for Using Emulsified Asphalt Equipment
1. Before spraying, the equipment must be checked for correct valve position. The hot asphalt added to the emulsified asphalt equipment must be operated within the temperature range of 160-180°C. The heating device can be used for long-distance transportation or long-term operation, but it cannot be used as an oil melting furnace.
2. When using a burner to heat asphalt in an emulsified asphalt plant, the asphalt level must exceed the upper surface of the combustion chamber, otherwise the combustion chamber will burn out. The emulsified asphalt plant must not be overfilled. The oil filler cap must be tightened to prevent asphalt spillage during transport.
4. When using the front control console, the switch should be set to front control. In this case, the rear control console can only control the nozzle raising and lowering.

As a professional manufacturer of emulsified asphalt equipment, we have long been dedicated to the production and research and development of high-quality asphalt equipment. To help you gain a more comprehensive understanding of our emulsified asphalt equipment, our professionals will now provide a brief explanation, which we believe will be helpful in understanding the product.
In an asphalt-water system, emulsifier molecules migrate between the asphalt and water interface. The hydrophobic groups of the molecules adsorb to the asphalt surface, imparting an electric charge, while the hydrophilic groups enter the aqueous phase. This bonds the asphalt particles to the water, reducing the interfacial tension between the two. Furthermore, because the asphalt particles have the same charge, they repel each other, preventing them from agglomerating, thus enabling the asphalt emulsion to maintain uniformity and stability for a certain period of time. The nature of the charge is determined by the charge of the hydrophobic groups or hydrocarbon chains of the emulsifier. If the charge is negative, the asphalt particles have a negative charge, and the resulting emulsion is anionic. Conversely, the emulsion is cationic. If the asphalt particles have both negative and positive charges, the emulsion is zwitterionic; there are also non-ionic asphalt liquids.

In the field of road construction, the technical adaptability of emulsified asphalt production equipment directly affects the efficiency of the project. This article analyzes the technical path for efficient production from three dimensions: equipment selection, core components, and cross-industry technology migration.
I. Equipment type and technical adaptability
Mainstream equipment is divided into mobile and fixed types. The ZMLR6000 equipment adopts a 304 stainless steel tank and a thermal oil heating system. The ±0.5% ratio accuracy meets the fineness requirements of high-grade roads ≤5μm, which is suitable for field operations. The YK6 unit realizes dual-mode heating through the RH6 colloid mill, heats to 100℃ within 45 minutes, supports continuous production of 20%-70% solid content, and has a daily production capacity of 120 tons, which is more suitable for small and medium-sized projects.
II. Core component technology breakthroughs
1. High-speed shear system: The German imported colloid mill adopts a stepped internal tooth structure with a rotation speed of 10,000rpm. The 0.05mm shear gap ensures that the asphalt particles are refined to 1-5μm, and the emulsion stability is improved by 30%.
2. Temperature control and energy-saving design: The waste heat recovery system reduces energy consumption by 30%, the 10㎡ heat exchanger achieves closed-loop energy conservation, and the ±0.5℃ temperature control accuracy can simulate the long-term aging process of asphalt.
3. Intelligent control system: The Internet of Things module supports remote early warning, and the SCADA system integrates 32 temperature sensors. The temperature difference is monitored in real time through dynamic thermal imaging, and the solid content deviation is controlled within ±1%.

The viscosity of emulsified asphalt equipment decreases with the increase of temperature during the production process. The power viscosity of emulsified asphalt equipment is about twice as high as every 12℃ increase. During processing, the culture medium asphalt barrel should be heated to liquid before demulsification. In order to better integrate the demulsification emulsified asphalt equipment capacity of the colloid solution mill, the culture medium asphalt barrel power viscosity is generally controlled to be about 200cst. The lower the temperature, the higher the viscosity, which increases the pressure of the asphalt barrel pump and the colloid solution mill, and the emulsion cannot be demulsified. However, on the other hand, in order to prevent the emulsified asphalt equipment from weaning when the finished product water evaporates, it is unlikely to overheat the culture medium asphalt barrel temperature. Generally, the finished product temperature at the inlet and outlet of the colloid solution mill should be less than 85℃.
One of the important methods to control the temperature and viscosity of emulsified asphalt equipment during processing is based on this. Everyone must carry out scientific operation according to the instructions of the emulsified asphalt equipment, so that the characteristics of the emulsified asphalt equipment can be fully presented. The development trend of the drying theory of emulsified asphalt equipment requires the stone resources to be processed, dried and heated. The reason for the emulsified asphalt equipment is that the quality of wet raw materials does not meet the requirements of asphalt mixture production and processing technology equipment companies.

The surface tension of asphalt and water is very different, and they will not be miscible with each other at room temperature or high temperature. However, when the emulsified asphalt equipment is subjected to mechanical actions such as high-speed centrifugation, shearing, and impact, the emulsified asphalt equipment makes it into particles with a particle size of 0.1~5μm, and dispersed in a water medium containing a surfactant (emulsifier-stabilizer). Since the emulsifier can be directional adsorbed on the surface of the emulsified asphalt equipment particles, the interfacial tension between water and asphalt is reduced, so that the asphalt particles can form a stable dispersion system in water. The emulsified asphalt equipment is an oil-in-water emulsion. This dispersion system is tea brown, with asphalt as the dispersed phase and water as the continuous phase, and has good fluidity at room temperature.
In a sense, emulsified asphalt equipment dilutes asphalt with water, thereby improving the fluidity of asphalt.

Emulsified asphalt equipment is a widely used asphalt equipment. Now its ultra-high performance has been widely praised by users. However, we must first ensure the safe use of emulsified asphalt equipment to fully demonstrate its performance; modified asphalt equipment is an asphalt binder made by adding rubber, resin, high molecular polymer, ground rubber powder or other fillers and other admixtures (modifiers), or taking measures such as mild oxidation of asphalt to improve the performance of asphalt or asphalt mixture; So how much do you know about the safe use and operation of modified asphalt equipment? Today, the editor will tell you;
Placement: The modified asphalt equipment should be placed on a flat place, and the front axle wheel should be fixed with sleepers and the tires should be dangling to ensure the stability of the machine during work.
Regularly inspect whether the mixer blades are deformed and whether the screws are loose.
Inspect whether the running direction of the mixing barrel is consistent with the arrow; if not, please replace the positive and negative poles of the wiring.
Before powering on, you should inspect and test run the empty vehicle, check for leakage, and check the idling of the mixing barrel. The normal speed is about 3 times faster when the empty vehicle is full. If the speed is wrong, you should stop the machine and check the asphalt tank.
Note: After the asphalt material is mixed, it is best to stop the machine for one hour, clean the drain material in the mixing barrel, pour in clean water, and clean the mortar. Then drain the water. Remember that there should be no water accumulation in the barrel to prevent the formula from changing, and the blades are prone to rust. During use, everyone should pay attention to these small links to avoid unnecessary losses to their work.

The additives in the production process of emulsified asphalt equipment can be divided into accelerators and retarders. In addition, the temperature and viscosity at that time need to be correctly controlled during production. How much do you know about this information? Let’s take a closer look:
The viscosity of asphalt decreases with the increase of temperature during the production of emulsified asphalt equipment. For every 12°C increase, its dynamic viscosity decreases by about one time. During production, the base asphalt should be heated to liquid state before emulsification. In addition, in order to adapt to the emulsification capacity of the colloid mill, the dynamic viscosity of the base asphalt is generally controlled to be about 200cst. The lower the temperature, the higher the viscosity, which increases the burden on the asphalt pump and the colloid mill, making it difficult to emulsify; but on the other hand, in order to prevent the demulsification caused by excessive vaporization and evaporation of water in the finished product during the production of emulsified asphalt, it is impossible to heat the base asphalt temperature too high. Generally, the finished product temperature at the outlet of the colloid mill should be controlled to be less than 85°C.
These are the main ways to control the temperature and viscosity of emulsified asphalt equipment during production. We must operate reasonably according to the instructions so that its performance can be fully demonstrated. If you have any questions, please feel free to consult us in time. We will continue to organize more information about emulsified asphalt equipment for you.

I believe that after a long period of contact with asphalt tanks, everyone knows that the working efficiency of emulsified asphalt equipment actually depends on the operator. The more experienced the operator is and the stronger his ability to deal with various emergencies is, the higher the working efficiency will be, and the safety will be guaranteed. Mastering more equipment-related knowledge is what every friend should pursue. Today, the editor will explain to you the details that need to be paid attention to when operating emulsified asphalt equipment:

Emulsified asphalt equipment improves the fluidity of asphalt: When the emulsified asphalt equipment is subjected to mechanical actions such as high-speed centrifugation, shearing, and impact, the emulsified asphalt equipment makes it into particles with a particle size of 0.1~5μm, and disperses it into a water medium containing a surfactant (emulsifier-stabilizer). Since the emulsifier can be directional adsorbed on the surface of the emulsified asphalt equipment particles, the interfacial tension between water and asphalt is reduced, so that the asphalt particles can form a stable dispersion system in water. The emulsified asphalt equipment is an oil-in-water emulsion.

Emulsified asphalt equipment plays an important role in road construction, and its production quality will directly affect the quality of facilities such as roads. In order to operate it better, we need to pay special attention to the following four points when applying emulsified asphalt equipment:
1. Before spraying, the emulsified asphalt equipment must check whether the position of each valve is correct. The hot asphalt added to the emulsified asphalt equipment must reach an operating temperature of 160~180℃. For long-distance transportation or long working time, a heating device can be used for insulation, but it cannot be used as an oil melting furnace.
2. When the asphalt in the emulsified asphalt equipment is heated by a burner, the asphalt height must exceed the upper plane of the combustion chamber, otherwise the combustion chamber will be burned.
3. The emulsified asphalt equipment cannot be filled too full, and the fuel filler cap must be closed tightly to prevent asphalt from overflowing during transportation.
4. This vehicle has two front and rear control consoles. When using the front control console, the switch must be turned to the front control. At this time, the rear control console can only control the lifting and lowering of the nozzle.
I believe that through the above description, everyone will be more comfortable when using emulsified asphalt equipment in the future. As for the relevant operating matters of the equipment, I will introduce them to you here today. If you want to know more information, please pay attention to the next explanation.

In the asphalt-water system, the emulsifier molecules move between the asphalt and water interface, and the water-loving groups of the molecules are adsorbed on the surface of the asphalt, making it charged, while the hydrophilic groups enter the water phase. This connects the asphalt particles with water, reducing the interfacial tension between the two. At the same time, because the asphalt particles have the same charge and repel each other, they are prevented from agglomerating with each other, so that the asphalt emulsion can remain uniform and stable for a certain period of time. The nature of the charge is determined by the charge of the hydrophobic group or hydrocarbon chain of the emulsifier. If it is negatively charged, the asphalt particles are negatively charged, and the emulsion formed is an anionic asphalt emulsion. Otherwise, it is a cationic asphalt emulsion. If the asphalt particles have both negative and positive charges, the emulsion is a zwitterionic asphalt emulsion; in addition, there is also a non-ionic asphalt liquid.

Emulsified asphalt equipment is an indispensable equipment in road construction and one of the basic equipment for waterproof coatings. What are the components of emulsified asphalt equipment? Today, we will explain the various parts of emulsified asphalt equipment in detail.
Required parts
Asphalt pump: a device for supplying asphalt to the colloid mill.
Emulsion pump: a device for supplying emulsion to the colloid mill.
Colloid mill: a device for mixing, homogenizing and emulsifying asphalt and emulsion.
Control system: a device for controlling the flow of asphalt and emulsion, and the start and stop of various pumps.
Emulsion blending: a device for mixing water, emulsifiers and other additives.
Water heating part: a device for heating water.

No matter the application of emulsified asphalt equipment or other related equipment, in the application of appropriate maintenance work, today we introduce professional technicians to do the following 3 points to effectively improve the utilization rate of asphalt equipment:
1. When the emulsified asphalt plant is out of use for a long time, the liquid in the pipeline and storage tank should be discharged, the lid should be sealed, kept clean, and all moving parts are lubricated. When it is used for the first time and disabled for a long time, the rust of the oil tank should be removed, and the water filter should be cleaned regularly.
2. When the outdoor temperature is lower than -5℃, the emulsified asphalt production equipment shall not store the product without insulation device, and it should be discharged in time to avoid freezing and demulsification of emulsified asphalt.
3. The gap between the stator and the rotor of the emulsified asphalt equipment should be checked regularly. When the machine cannot meet the smaller gap requirements, the stator and rotor should be replaced.

For each equipment used, certain safety knowledge must be followed. For the use of emulsified asphalt equipment, detailed instructions are given:
1. Placement: The emulsified asphalt equipment should be placed on a flat place, the front axle should be fixed to the sleepers, and the tires should be dangling. The machine should not be fiddled with at will to affect normal operation.
2. Regularly check whether the mixer blades are deformed and the screws are loose.
3. Check whether the running direction of the mixing drum is consistent with the direction of the arrow. Please replace the positive and negative poles of the terminal.
4. Before turning on the power, check the no-load test run, check for air leakage, and check the idling speed of the mixing barrel. The normal speed is about 3 times faster than the empty car. If not, stop the inspection.
5. If the asphalt material is stopped for one hour after mixing, clean the mixing barrel, pour in clean water, and clean the mortar. Then drain the water. Remember that there should be no water in the barrel to prevent the formula from changing, so that the page and other links will rust. Sinoroader will provide you with more safe emulsified asphalt knowledge, please continue to browse.

For users of equipment, the amount of material used is the focus of every user. We should attach great importance to this link in the production process. The following is an analysis of the amount of emulsifier used by Gaoyuan manufacturers.
When emulsified asphalt equipment is emulsifying asphalt, the asphalt temperature is better controlled at above 130°C to have better fluidity; 2. The amount of emulsifier is generally 8-14‰ of emulsified asphalt, that is, 8-14kg per ton of emulsified asphalt (asphalt content is more than 50%), and the temperature is 60-70°C. The emulsifier should be used in the middle and upper limit of the production, 10 kg per ton of emulsified asphalt, or 20 kg per ton of water (asphalt content is 50%); the amount of BE-3 emulsifier is generally 18-25‰ of emulsified asphalt, that is, 18-25kg per ton of emulsified asphalt (asphalt content is more than 50%), and the emulsifier solution temperature is 60-70°C. The emulsifier should be used in the upper and middle limits in the first production to ensure successful production. Use 24 kg per ton of emulsified asphalt, or 48 kg per ton of water (asphalt content is 50%). After the production goes smoothly, the dosage can be reduced according to actual conditions.

Emulsified asphalt equipment is a special equipment for producing emulsified asphalt. The emulsified asphalt produced by emulsified asphalt equipment is used in many industries. I wonder how much you know about the emulsified asphalt produced by emulsified asphalt equipment. Let’s take a look at them one by one:
Slurry seal is a cold mix asphalt mixture with the advantages of aggregate and asphalt mixing. Under normal circumstances, similar graded slurry seal has a higher modulus than hot mix asphalt mixture, so it is often used to fill road rutting. The higher stability has a higher resistance to deformation. The mixture is usually composed of harder fine aggregate grading and wear-resistant aggregate with high sand equivalent, especially micro-seal and polymer-modified seal. This greatly increases the strength and integrity of the road surface. This makes the road surface have high wear resistance and excellent deformation resistance. Emulsified asphalt emulsion is also easy to use on a mobile slurry seal paver, where mixing and admixtures are used for chemical control to meet maintenance needs.

All kinds of base layers have the problem of strength formation and growth (Emerson). The strength is gradually generated during the curing process, and the internal structure will become more and more dense. The test shows that when the semi-rigid base layer is sprayed with penetration oil before the cement (material: powdered water-hardening inorganic cementitious material) has not yet hardened, the penetration depth is deep; with the increase of age and strength, the penetration effect of the penetration oil is getting worse and worse.
At the same time, timely spreading of penetration oil has a good retention effect on the moisture in the base layer, preventing the evaporation of moisture, ensuring the formation of the strength of the base layer, and the surface of the base layer is not easy to loosen. The penetration oil also protects the semi-rigid base layer from cracking due to exposure to the sun. Furthermore, since the base layer is no longer covered and watered for curing, the temperature inside the base layer is high, which is conducive to the growth of strength.

Emulsified modified asphalt equipment is classified according to the production process and can be divided into three types: intermittent emulsified modified asphalt equipment, semi-continuous emulsified modified asphalt equipment, and continuous emulsified modified asphalt equipment. During the production of emulsified modified asphalt equipment, demulsifier, acid, water, and latex modified materials are blended in a soap mixing tank, and then pumped into the asphalt into the colloid mill. After a can of soap is used up, the soap is redispensed, and then the production of the next can is completed.
The emulsified modified asphalt equipment mentioned here includes hot water pumps and circulation pumps. This type of centrifugal water pump generally uses a pipeline centrifugal pump. There is a sewage outlet at the bottom of the pipeline centrifugal pump. Pay attention to the sewage outlet at the bottom of the emulsified modified asphalt equipment pump. The water in the water tank is released through the filter valve. Some emulsified modified asphalt equipment does not have a filter valve to save equipment costs, so it can only be emptied by loosening the flange bolts at the bottom. There are basically two methods of moisturizing emulsion pumps for emulsified modified asphalt equipment on the market, gear oil pumps or centrifugal water pumps. The gear oil pump can only drain the liquid in the pump through the connecting flange of the pipeline. The centrifugal water pump carries out sewage treatment through its own sewage outlet.
When used in the production of emulsified modified asphalt equipment, depending on the modified material technology, the latex pipeline can be connected in front of the colloid mill or behind the colloid mill, or there may be no latex pipeline and it must be made manually. Add the required amount of latex into the soap jar.

Emulsified modified asphalt equipment includes sewage treatment, water storage tank, water metering and verification temperature control system, asphalt storage tank, asphalt external temperature control system, hot water pump soap seasoning system, soap storage tank, soap mixing pump, soap external temperature control system and metering and verification system, filter, hot asphalt mixing pump and metering and verification system, pipeline black anti-static tweezers, emulsified asphalt cooling system and retrieval equipment, product tank and electrical control system.
The whole set of procedures is modularized, and customers can freely match and use according to their needs. The application of each part of the equipment is as follows: Sewage treatment system: Mechanically filter and adsorb the general drinking water to react with epoxy resin to convert the strong drinking water into pure softened water, reduce the water holding capacity, and improve the emulsion effect of asphalt or asphalt concrete.

How to reduce the energy consumption of emulsified asphalt production equipment is a concern of many users, and is also an issue that many manufacturers attach great importance to. Therefore, today Sinoroader, as a manufacturer of emulsified asphalt production equipment, would like to take this opportunity to share with you how to reduce the production of emulsified asphalt. Equipment energy consumption method.
Since emulsified asphalt appears as a finished product in emulsified asphalt production equipment, and the outlet temperature of ordinary emulsified asphalt is about 85°C, the outlet temperature of emulsified modified asphalt is above 95°C, so there is a lot of latent heat in emulsified asphalt, but emulsified asphalt The production equipment does not make good use of them, but directly enters the finished product tank, allowing the heat to be lost at will, resulting in a waste of energy.

What key points should be paid attention to when feeding emulsified asphalt equipment? When it comes to emulsified asphalt equipment, I don’t know how much you know about it? What should you pay attention to when adding materials?
The black anti-static tweezers grinding wheel of the emulsified asphalt equipment does not have a heated collet. Before use, you must add the appropriate amount of diesel and let the black anti-static tweezers circulate for 3 to 5 minutes to generate heat (the temperature after operation is 80 ~100 degrees) open the stop valve on the oil delivery pipe to drain the diesel engine in the engine. The temperature of the black anti-static tweezers grinding wheel must be around 80 to 100 degrees before the material can be loaded and put into production. If there is a heated collet, the grinding wheel must be heated before starting, and then the material is loaded and put into production.

How to reduce energy consumption of emulsified asphalt machinery is a concern of many users and many manufacturers. Therefore, today, Sinosun Company, as a manufacturer of emulsified asphalt equipment, would like to take this opportunity to share with you the method of reducing energy consumption of emulsified asphalt machinery.
Since emulsified asphalt appears as a finished product in emulsified asphalt machinery, and the outlet temperature of ordinary emulsified asphalt is about 85℃, and the outlet temperature of emulsified modified asphalt is above 95℃, there is a lot of latent heat in emulsified asphalt, but the emulsified asphalt equipment does not make good use of them, but directly enters the finished product tank, allowing heat to be lost at will, resulting in energy waste.

In our daily life, we can often see emulsified asphalt equipment. Its appearance has brought us great convenience. So what is the difference between its modification process? Below, the editor will give you a brief introduction to the relevant knowledge points.
1. Emulsified asphalt equipment first emulsifies and then modifies: This is a relatively simple way to make modified emulsified asphalt. The production process is to grind hot asphalt and emulsifier soap together through a colloid mill to make ordinary emulsified asphalt, and then add latex-like modifiers to the emulsified asphalt through mechanical stirring to make modified emulsified asphalt. The characteristic of this method is that it does not require high equipment.

There are many types of emulsified asphalt (composition: asphaltene and resin) equipment. Emulsified asphalt (composition: asphaltene and resin) equipment can be divided into intermittent operation type, semi-continuous operation type, and Continuing the three operating types, what is the knowledge about different types of emulsified asphalt equipment?

The black anti-static tweezers grinding wheel of the emulsified asphalt equipment does not have a heated collet. Before use, you must add the appropriate amount of diesel and let the black anti-static tweezers circulate for 3 to 5 minutes to generate heat (the temperature after operation is 80 ~100 degrees) Open the stop valve on the oil delivery pipe to drain the diesel engine in the engine. The temperature of the black anti-static tweezers grinding wheel must be around 80 to 100 degrees before the material can be loaded and put into production. If there is a heated collet, the grinding wheel must be heated before starting, and then the material is loaded and put into production.

Emulsified asphalt equipment hot-melts basic colored asphalt and mechanically distributes tiny colored asphalt particles in an aqueous solution containing emulsifier to form a liquid colored asphalt material. The cement emulsified asphalt equipment mortar used in slab ballastless track construction uses cationic emulsified asphalt equipment. The purpose is to adjust the elasticity, toughness and durability of the cement emulsified asphalt equipment mortar. Polymers are often used to modify the asphalt.
