Reasonably control the temperature and viscosity of bitumen decanter machinery and equipment

As we all know, emulsified bitumen is a single-component black viscous liquid that can combine the roadbed and the pavement to improve the performance and service life of the road. So what problems should be paid attention to when using emulsified bitumen? Let’s follow the editor of Sinoroader Group, an emulsified bitumen manufacturer, to learn about it.

As a manufacturer with many years of experience in emulsified bitumen construction, Sinoroader Group believes that everyone needs to pay attention to the following 2 points when using it:

This set of emulsified asphalt production equipment includes water treatment, water storage tanks, water active metering and temperature control systems, asphalt storage tanks, asphalt external temperature systems, hot water pump soap batching systems, soap temporary storage tanks, soap transfer pumps, soap liquid It consists of external temperature system and metering system, filter, hot asphalt transfer pump and metering system, three-stage pipeline emulsifier, emulsified asphalt cooling system and recovery equipment, product tank and electrical automatic control system.
The entire process is modularly designed, and users can freely combine and select according to their needs. The equipment of each part is used as follows: Water treatment system: Mechanical filtration of ordinary tap water absorbs resin exchange reactions, turning high-hardness tap water into pure soft water and reducing water tension. , enhance the emulsification effect of asphalt or modified asphalt.

Asphalt mixing plant is one of the main equipment for producing asphalt concrete. It can mix asphalt, gravel, cement and other materials together in a certain proportion to obtain the products required for highway construction. In order to ensure its operating effect, the asphalt mixing station also needs to be powered on for trial operation before it is officially put into work.

After the rubber bitumen storage tank is cleaned, the wood chips are sent to the rubber bitumen storage tank, and the wood chips and the bottom of the rubber bitumen storage tank are wiped with wood chips. The dirt and wood chips in the bitumen tank can be weathered naturally. The rubber bitumen storage tank is not allowed to be damaged. Check the technical specifications of the underwater concrete processing equipment and ventilation equipment.
The bottom of the rubber bitumen storage tank drain pipe is discharged from the drainage pipe, and the waste water is discharged into the empty tank or other containers through the inlet and outlet and the self-draining pipe. Open the Shenzhen manhole into the plastic suction pipe and pave the Shenzhen manhole with asbestos to reduce the discharge of oil and gas. When manually pumping the bottom oil, two people should be operated to improve the labor efficiency of the workers and send the fuel tank to supervision.

Emulsified asphalt (ingredients: asphaltene and resin) heating tank is a new type of equipment for heating emulsified asphalt. Its appearance replaces the traditional thermal oil heating equipment, which brings great convenience to our users and improves work efficiency. Then let’s take a detailed look at how it is better than the traditional thermal oil heating equipment.
Emulsified asphalt (ingredients: asphaltene and resin) heating tank is another new type of emulsified asphalt heating storage equipment developed by technically separating the characteristics of traditional thermal oil heating emulsified asphalt tanks and internal heat part (part) rapid emulsified asphalt heating tanks. The automatic circulation program of the asphalt heating equipment enables the asphalt to automatically enter the heater, dust collector, induced draft fan, asphalt pump, asphalt temperature display, water level display, and steam generator as required.
It consists of pipeline and asphalt pump preheating system, pressure relief system steam combustion system, tank cleaning system, oil unloading tank installation, etc. All are installed on the tank body (inside) to form a compact integrated structure. It fully compensates for the shortcomings of traditional thermal oil heating equipment, such as long heating time and high energy consumption.

Synchronous gravel sealer fog sealer is a method of road maintenance. Some roads have network cracks, cracks and holes after a few years of use. The effective method is fog seal technology. The cost is very low. After the fog seal, due to the large fluidity of the material, it can penetrate into the aggregate and flow into the cracks to “transfuse” the road surface, restore the asphalt adhesion of the road surface, fill small cracks and gaps, prevent water from penetrating the road surface, and keep the road surface performance for 2 to 3 years, delaying the high maintenance cost and improving the economic benefits.

1. When operating an asphalt spreading truck, first check whether the machinery, spreading devices, protective and fire prevention equipment are complete and effective.
2. It is strictly prohibited to use non-specified fuel as the fuel for the heating system. The fuel is not allowed to overflow outside the tank. Generally, the oil level should be 20-30cm lower than the upper end of the overflow pipe.

Sinoroader emulsifier does not need to add acid or adjust pH value in the production of emulsified asphalt, thus reducing the process, reducing equipment maintenance, saving labor and materials. It reduces the cost of emulsified asphalt, produces acid-free, eliminates equipment corrosion emulsion, does not consider anti-corrosion measures in the selection of equipment, and greatly reduces the capital investment of equipment.
Main technical indicators:
Active ingredient content 40±2%
pH value 8-7
Appearance: yellow or dark yellow liquid
Odor: non-toxic, aromatic gas
Solubility: soluble in water and some organic solvents
Temperature ratio:
Water temperature: 70℃-80℃
Asphalt temperature: 140℃-150℃

Asphalt ratio: water = 4:6
Precautions:
The temperature of the emulsifier aqueous solution should not exceed 70%
When the temperature is low, the product is in a paste or paste, and the heating is variable.
Different varieties of asphalt should adjust the amount of emulsifier, and the use test should be derived from the test.

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.

Asphalt melting equipment is an important road construction tool used to heat asphalt to the appropriate temperature for construction. It can provide reliable solutions and make road construction more convenient. The working principle of this equipment is to heat the asphalt to the appropriate temperature through a heater, and then transport the hot asphalt to the construction site through a conveying system.

I believe everyone is familiar with the relevant knowledge about modified bitumen equipment. As users continue to increase its application, we have also talked about it a lot in the above articles and learned that it is mainly engaged in the production of modified bitumen. Production, in order to further enhance users’ understanding of it, professionals summarize its relevant characteristics as follows:

Everyone must be familiar with slurry sealing and micro-surfacing. But do you know their 7 construction steps?
Slurry sealing and micro-surfacing were both early preventative highway protection technologies. Its function is to ensure the smooth use and extended life of the highway. The construction steps are as follows:

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.

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.

The slurry seal truck is one of the main maintenance methods of highways. The slurry seal is made of emulsified asphalt as the binding material, well-graded mineral materials, fillers, water and additives, etc., mixed in a certain proportion. The slurry mixture is evenly spread on the old road surface to be treated with a sealing truck, and is firmly combined with the original road surface to form a new thin layer of asphalt mixture. So what preparations need to be done before construction? Let’s find out below.

Asphalt spreader vehicle is an intelligent and automated high-tech product that specializes in spreading emulsified asphalt, diluted asphalt, hot asphalt, high-viscosity modified asphalt, etc.
Asphalt spreader is used for spreading the penetration oil, waterproof layer, and bonding layer of the bottom layer of the asphalt pavement of high-grade highways. The spreader consists of a car chassis, an asphalt tank, an asphalt pumping and spraying system, a thermal oil heating system, a hydraulic system, an ignition system, a control system, a pneumatic system, and an operating platform.
Asphalt spreader is cumbersome to operate. On the basis of absorbing various technologies of similar products at home and abroad, it increases the quality technology content of construction and the humanized design of outstanding improvement of construction conditions and construction environment. Its reasonable and reliable design ensures the uniformity of asphalt spreading, the computer control is stable and reliable, and the technical performance of the whole vehicle has reached an advanced level.

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.

Highway preventive maintenance construction methods and application scenarios are key measures to ensure the long-term performance of highways and extend their service life. The following are common construction methods and their application scenarios:

1. There are generally three ways to heat emulsified bitumen plant: gas heating, heat transfer oil heating and open flame heating. The first is the gas heating method of emulsified bitumen plant. The gas heating method of emulsified bitumen plant requires the use of the fire pipe to transport the high-temperature smoke generated by high-temperature combustion through the fire pipe.
2. The heat transfer oil heating method of emulsified bitumen plant mainly uses heat transfer oil as a medium for heating. The heat transfer oil heating method has extremely high requirements for fuel. The fuel must be fully burned and the product must be transferred to the heat transfer oil after sufficient heat is transferred to the heat transfer oil pump for heating.
3. The open flame heating method of emulsified bitumen plant is the most direct and convenient heating method. Whether in terms of convenient transportation or coal consumption, the open flame heating method is the fastest choice, simple operation, sufficient fuel, structural design, and labor intensity are relatively reasonable.

When emulsifying asphalt, the temperature of asphalt should be controlled above 130℃ to ensure good fluidity; the amount of BE-1, 2, and A1 emulsifiers is generally 8-14‰ of emulsified asphalt, that is, 8-14kg per ton of emulsified asphalt (asphalt content is above 50%), and the temperature is 60-70℃.
The emulsifier should be used in the upper and middle limits of the first production, preferably 10kg per ton of emulsified asphalt, or 20kg 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 above 50%), and the temperature of the emulsifier solution is 60-70℃.
During the first production, the emulsifier should be used in the middle and upper limit dosage to ensure successful production. It is best to 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.

1. Different production processes
Emulsified asphalt and asphalt are both extracted from petroleum, but their production processes are different. Asphalt is separated from crude oil by high-temperature treatment, and then processed through a series of complex processing processes such as distillation and fluidized hydrogenation. Emulsified asphalt, on the other hand, is made by adding an emulsifier, mechanical shearing or ultrasonic “emulsification” reaction, dispersing oil and water to form an emulsion, and then adding an appropriate amount of acid catalyst.
2. Different usage scenarios
Asphalt is suitable for paving in different places such as roads, bridges, airport runways, and parking lots. Emulsified asphalt is particularly suitable for use under more stringent conditions such as deep road repair and bridge deck waterproofing. Because emulsified asphalt produced by emulsification technology has better performance and can better adapt to complex usage environments.
3. Different characteristics
Asphalt is a black, viscous substance with fluffy fibers, a high melting point, high hardness, and easy aging. In comparison, emulsified asphalt is lighter in color, light gray or milky white, with moderate viscosity and uniformity, good adhesion, good water and weather resistance, and not easy to age.
4. Different use effects
Although asphalt works well on the road surface, it also has certain difficulties in construction and maintenance. Emulsified asphalt is more convenient to use and can be easily mixed with other materials during construction, so it is widely popular and has better use effects.
In summary, there are obvious differences between emulsified asphalt and asphalt in production process, usage scenarios, characteristics, and use effects, and appropriate materials need to be selected according to different needs.

There are many types of bitumen emulsifiers, and there are many classification methods. For specific classifications, please refer to previous articles. The raw materials required for the production of emulsion bitumen are: bitumen, water and bitumen emulsifier. High-standard emulsion bitumen requires adding additives and adjusting acid. According to whether acid adjustment is needed in the emulsion bitumen production process, it can be divided into two categories: emulsion bitumen that requires acid adjustment and emulsion bitumen that does not require acid adjustment.

Modified (rubber powder) bitumen equipment, one of the road maintenance equipment. It is a kind of equipment that measures, mixes and develops SBS, rubber powder and asphalt.
Modified (rubber powder) bitumen equipment is a set of wet modification processing technology, which mainly consists of modified material metering and promotion, bitumen rapid heating, asphalt metering, high-intensity mixing tank, mixed material transfer pump, development tank, colloid mill, Control system and other components.

We have conducted in-depth research on asphalt distributors and have accumulated a lot of production technology experience. We have conducted professional and in-depth research on some problems existing in the market to provide convenience for everyone in future production applications.
Every time when spraying asphalt, the asphalt distributor does not spray asphalt. Troubleshooting. The asphalt distributor does not spray asphalt. It is a common fault. The following teaches you how to solve the problem of not spraying asphalt.
1. No asphalt spraying
Analysis of the reasons may be the following reasons:
1. Is the asphalt pump working?
2. Are the valves adjusted correctly?
3. Is the pump or pipeline blocked?
2. Troubleshooting method
1. Check whether the hydraulic system is working properly?
2. After adjusting the valve position, the asphalt distributor must be cleaned to avoid pipeline blockage when used next time. Because the asphalt distributor has different high and low configurations, it can spread various high-viscosity and high-temperature modified asphalts and rubber asphalt in high configuration. If you mistakenly use a low-configuration asphalt truck to spread this type of asphalt, you must spray the asphalt inside the entire vehicle clean after the first use. After spraying, in order to leave no residual asphalt, you can use waste diesel to clean it. Our company’s vehicles are equipped with air cleaning and gravity cleaning devices. Diesel cleaning is a reliable cleaning method.
