What are the basic concepts and production process of emulsified modified asphalt equipment?

Modified material bitumen stripper, if the definition is simple, is an bitumen stripper. If described in detail, modified materials such as rubber powder or other fillers are added to the bitumen stripper, or an bitumen stripper is used to Block chemical substances such as photooxygen catalysis. The first is to change the chemical composition of the bitumen stripper, and the second is to use modified materials to equip the stripper with a certain spatial network structure, thereby improving its performance. Modified bitumen strippers mainly include vulcanized rubber and thermoplastic polyurethane elastomer modified bitumen strippers, plastic and anti-corrosion coating modified bitumen strippers and polymer modified bitumen strippers.

There are certain standards for the composition and mix ratio of micro-surfacing, and a wide range of materials are used, including polymer-modified emulsified asphalt, various aggregates, cement, water, additives, etc. Raw material quality has a significant impact on microsurfacing performance, so understanding the performance of each component and the key factors that influence its performance is critical to ensuring the quality of your microsurfacing mix.

There is a wide variety of asphalt melting equipment on the market, including different brands and models. The prices of these devices vary widely, depending mainly on factors such as their features, performance, and specifications.
Asphalt melter equipment produced by some large brands such as Sinoroader usually has higher quality and reliability, so the price is relatively higher. However, they also offer longer service life and better maintenance support.

The hydraulic bitumen decanter equipment produced by our company uses thermal oil as the heat carrier and has its own burner for heating. The thermal oil heats, melts, debarks and dehydrates the asphalt through the heating coil. This device can ensure that the asphalt does not age, and has the advantages of high thermal efficiency, fast barrel loading/unloading speed, improved labor intensity, and reduced environmental pollution.

The bitumen (composition: asphaltene and resin) drum melting machine adopts a self-heating integrated structure, which integrates the thermal oil boiler used in the old asphalt drum melting machine and the barrel removal equipment itself, reducing the volume of the entire equipment and significantly It reduces equipment investment (actual significance: it is the accumulation of future profits), saves the space occupied by the equipment and the logistics cost of switching sites. The combustion chamber is placed inside the equipment itself, which greatly reduces thermal damage and improves heat utilization.

Synchronized gravel sealing is a process technology for treating cracks in asphalt pavement, and it is currently a road construction and pavement maintenance technology with low energy consumption and high cost performance. Do you know what its six technical features are? If you don’t know, just follow the editor of Sinoroader and take a look.

According to the configuration, layout and controllability of bitumen melting equipment, bitumen melting plant can be divided into three types: mobile, transportable and portable. What should be paid attention to in the production of bitumen melter equipment of different sizes? Let’s learn about it below!
Bitumen melting plant is to fix the demulsifier mixing equipment, black anti-static tweezers, asphalt pump, automatic control system, etc. on a special support chassis. Because the bitumen melter equipment can directly change the production site, it is suitable for the production of emulsion bitumen in construction sites with decentralized projects, small usage and frequent movement.
The main components of the bitumen melting equipments are installed in one or two 60 standard containers. The bitumen melting plant is loaded and transported separately to complete the relocation of the construction site. With the help of asphalt melting equipments hoisting equipment, it is quickly installed and put into operation. Such bitumen melter plant has large, medium and small different configurations, which can meet different project requirements.

The bitumen decanter equipment is mainly composed of barrel removal shell (BOX), hoisting mechanism, hydraulic booster and electrical control system. The shell is divided into two chambers, the left and right chambers. The upper chamber is a chamber for melting a large barrel of bitumen (definition: the transformation process of a substance from solid to liquid). There are heating coils evenly distributed around it.

Is the performance of Sinoroader’s fully automatic emulsified asphalt production equipment stable and unstable? To be honest, whether the performance of a product is stable or not can only be known through practice, right?
Chairman Mao, the great leader of China, once said, “Without practice, there is no right to speak.” Yes, people who have never used it naturally have no right to speak. Now the editor will talk about the fully automatic emulsified asphalt production equipment that I am using!

Asphalt emulsifier is an emulsifier that belongs to the category of surfactants and is a raw material for the production of emulsified asphalt.
Emulsifiers are divided into: synthetic emulsifiers, natural emulsifiers, inorganic powder emulsifiers, etc. Currently, synthetic emulsifiers are widely used. Asphalt emulsifier is a type of chemical organically synthesized surfactant.

Road repair Keep the road to maintain the performance of the road, restore the damaged part in time, ensure the safety, comfort and smooth driving, save transportation costs and time; Correct technical measures should be taken to improve the quality of the project, extend the service life of the road, and postpone the reconstruction time. With the performance, the damaged part is restored in time to ensure the safety, comfort and smooth driving, saving transportation costs and time; Correct technical measures should be taken to improve the quality of the project, extend the service life of the road, and postpone the reconstruction time.

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.

To ensure good operation of asphalt melting equipment and extend its service life, regular maintenance and repairs are required. The following are specific maintenance and repair steps:
First, various parts of the equipment, including heating elements, pipes, valves, etc., need to be inspected regularly to make sure they are not worn or damaged. If any problems are found, they should be repaired or replaced immediately.

Asphalt used to pave roads. It can be obtained by regular vacuum distillation of crude oil with appropriate properties, and can also be obtained by shallow oxidation of vacuum residue or propane deasphalting process. It can also be prepared by mixing asphalt of different duction and injection degree

Friends who are ready to get started have a surprise today. The editor will give you a brief introduction on how to produce emulsified asphalt.

The viscosity of the bitimen melter equipment decreases as the temperature increases during the production process. Its output viscosity is about twice as high as every 12°C increase. During production, the base bitimen melter equipment must first be heated to a liquid state and then emulsified. In order to better integrate the emulsification ability of colloid milling, the viscosity of base bitimen melter is generally controlled to be about 200 cst. The lower the temperature, the higher the viscosity, which increases the pressure on the bitimen melter pump and colloid milling, making emulsification impossible: However, on the other hand, in order to prevent the asphalt debarrel equipment from weaning when the moisture of th

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.

Changing the color of asphalt pavement is an important project aimed at improving the beauty of roads, optimizing traffic signs and enhancing urban landscape effects. The following is a detailed introduction to the color change of asphalt pavement:
1. Color change method
Using pavement color change spray:
Spray directly on the original asphalt pavement surface to make the road surface look brand new.
This method is simple and fast to construct, with bright and lasting colors, and will not change the structure of the pavement.

In addition to being used according to regulations, modified bitumen equipment should also be maintained regularly in order to effectively extend the service life of modified bitumen equipment. The delivery pump of modified bitumen equipment, as well as its motor and reducer, need to be maintained in accordance with the specifications of the instructions. If the modified bitumen equipment is parked for a long time, the liquid in the tank and pipeline needs to be drained, and each moving component also needs to be filled with grease. The dust in the control box of the modified bitumen equipment needs to be cleaned once every six months. A dust blower can be used to remove dust to prevent dust from entering the machine and damaging parts. The micro powder machine needs to add unsalted butter once for every 100 tons of emulsified bitumen produced.

The fine surface is made of stone with a single particle size, which has high wear resistance and anti-slip properties. The construction of the fine surface adopts mechanized construction, which requires less manual labor and has the characteristics of fast construction speed, anti-skid and noise reduction.
The special bonding material for fine surfaces produced by Sinoroader Group has the characteristics of good bonding performance and good durability. The specific construction process is roughly as follows:

Preventive pavement maintenance is a periodic mandatory maintenance measure, which is taken to restore the pavement surface service function when the pavement structure strength is sufficient and only the surface function is attenuated. New preventive maintenance technologies such as super-viscous fiber-added low-noise micro-surfacing and synchronous gravel seal have been widely used on the main lines of national highways, and the construction effect has been widely praised by customers.
Super-viscous fiber-added low-noise micro-surfacing starts with the gradation of micro-surfacing and the main material modified emulsified asphalt. By reducing the structural depth of the micro-surfacing and changing the distribution state of the coarse and fine materials on the surface of the micro-surfacing, the driving noise is reduced, while ensuring its anti-skid performance, effectively improving its adhesion, waterproofness, durability and crack resistance, and can solve the defects of easy detachment, excessive noise and reflective cracks of ordinary micro-surfacing.

Bitumen decanter equipment can be placed in a complex system as an independent unit, replacing the existing heat source de-barreling method, or in parallel as a core component of a large set of equipment, or it can work independently to meet the requirements of small-scale construction operations.
The Sinoroader bitumen decanter device is mainly composed of a de-barreling box, a lifting mechanism, a hydraulic thruster and an electrical control system. The box is divided into two chambers, the upper chamber is a barreled bitumen melting chamber, and heating coils are evenly distributed around it. The heating pipe and the bitumen barrel mainly exchange heat in a radiation manner to achieve the purpose of bitumen de-barreling. Several guide rails are the tracks for the bitumen barrel to enter. The lower chamber is mainly to continue heating the bitumen removed from the barrel to make the temperature reach the suction pump temperature (100℃), and then the asphalt pump is pumped into the upper chamber. At the same time, an empty barrel is pushed out at the rear end outlet. There is also an oil tank on the platform at the entrance of the asphalt barrel to prevent the dripping bitumen from flowing out.
The inlet and outlet doors of the device adopt a spring automatic closing mechanism. The door can be automatically closed after the asphalt barrel is pushed in or out to reduce heat loss. A temperature gauge is installed at the asphalt outlet to observe the asphalt outlet temperature. The electrical control system can control the opening and closing of the hydraulic pump and the reversing of the electromagnetic reversing valve to realize the advance and retreat of the hydraulic cylinder. If the heating time is extended, a higher temperature can be obtained. The lifting mechanism adopts a cantilever structure. The bitumen barrel is lifted by an electric hoist, and then moved horizontally to place the bitumen barrel on the guide rail. A temperature gauge is installed at the outlet of the asphalt meltering equipment to observe its outlet temperature.

Synchronous gravel sealing technology refers to the use of special synchronous gravel sealing truck equipment to lay and roll prepared gravel, asphalt and other materials to build a single layer of asphalt gravel wearing layer, which is important for highway pavement. protection of. From the perspective of characteristics, it is simple and easy to implement. It has obvious effects on the prevention of highway diseases, problem solving, later maintenance, and improvement of grade protection. It can also well extend the service life of highways.

Contemporary roads and pavements have undergone many changes: traffic volume and driving frequency have increased significantly, the axle load of logistics trucks has continued to increase, one-way driving in separate lanes has been widely implemented, and regulations have further improved the anti-flow resistance of the ground, that is, the work of modified asphalt equipment under high temperatures ability;

With the rapid development of our country’s social development and the continuous development of economic and information technology, modern highway construction is also developing rapidly, and the requirements for ground structural materials are becoming higher and higher, and Asphalt concrete bonding raw materials are inseparable from modified asphalt equipment. So besides these influencing factors, what other reasons does the company have that people don’t understand? Let’s analyze it together.
There are some asphalt concrete equipment on the market, because they have not solved the problem of asphalt clogging before grinding, there are not enough preparation equipment and grinding equipment, the structure is unscientific, and the entire grinding process cannot achieve a certain particle size, resulting in modification. The product productivity of asphalt equipment is low and the product quality is unstable. It requires continuous grinding for a long time, creating problems. This will not only greatly increase energy consumption, increase costs, make product quality unstable, and affect the speed of highway construction.

Asphalt anti-sticking release agent is a product used in the construction of hot asphalt mixture to solve the asphalt anti-sticking problem. It is used to replace diesel and vegetable oil! There are all kinds of things about the effect of asphalt anti-sticking release agent. How to use asphalt anti-sticking release agent?
Before use, stir the release agent evenly, spray or apply the original liquid evenly on the surface of construction equipment such as rubber-wheeled rollers, transport carriages, paver hoppers, ironing plates, etc.; or add water to the roller water tank after dilution, stir evenly and spray automatically for use.
When preparing to start construction, when the roller tires are cool or the temperature is low, you should first apply the roller tires with the release agent original liquid, and then start rolling. At the beginning, you need to apply more release agent. After the temperature of the tires rises, you can apply it normally or less. If you use intermittent spraying of release agent, you should spray more frequently at the beginning of construction.
When adding water, we recommend a ratio of 10-15 times. It will be better to use 10 times the water ratio. If you think the cost is high and want to add more water, it is also possible, but try to use less than 15 times the water ratio. If it is modified asphalt, it is recommended to use less than 8 times, and 7 times the water ratio is recommended.

Emulsified asphalt is an aqueous suspension of asphalt particles with high interfacial energy. This suspension state is thermodynamically unstable and has the potential to reduce its interfacial area (i.e., through the coagulation process) to a stable state. Preventing this coagulation state (dispersion destruction) is the stabilization effect of the emulsifier protective layer. The stability of emulsified asphalt refers to the ability of asphalt particles to aggregate and cause phase separation, and also refers to the time required for emulsified asphalt to reach equilibrium. That is, the time for asphalt particles to aggregate and separate from water. How can we increase this time? How to prevent emulsified asphalt from demulsifying?

For the relevant knowledge of modified asphalt equipment, we have more or less introduced it in the above articles. I believe that most users also have some simple understanding of it. Today we also mastered:
In order to meet the different requirements of customers, the configuration and process of the equipment produced by the manufacturers of modified asphalt equipment are diversified. There are fixed production types, mobile types, and imported main machines, but the imported main machines are expensive, so most customers configure domestic pipeline emulsifiers or colloid mills. In terms of the degree of automation, there are fully automatic production and semi-automatic production. Regardless of the form of production, each has its own advantages and disadvantages. What kind of process and configuration is used depends on the annual production volume and the customer’s requirements for equipment, product performance requirements and other factors. I hope that these introductions can help users choose to a certain extent.
