Why does modified asphalt equipment need to be updated and upgraded?

Fog seal is an asphalt pavement maintenance construction method.
When the asphalt pavement has increased water permeability, loss of fine aggregate, cracks, pitting, etc., a fog seal layer can be used for pavement repair. The bonding material of the fog seal layer is fluid, can repair cracks and gaps, and can heal cracks below 0.3. After construction, the oil content of the road surface is increased, the anti-sticking aggregate is loosened, and it can play a waterproof role.
Before construction, the original road surface should be surveyed and analyzed to determine the construction bonding materials and spray volume.
So what precautions should be taken during construction?

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.

The modified asphalt equipment produced by Sinoroader can produce SBS, rubber powder, SBR, and PE modified asphalt manually and automatically. Some of its configurations and uses are as follows:
1. Filter: The specially made asphalt filter can effectively filter impurities and foreign matter in the high-temperature matrix asphalt to prevent damage to subsequent equipment.
2. Matrix asphalt heater: The spiral plate or shell and tube heat exchanger is used to quickly heat the matrix asphalt through heat transfer oil to meet the needs of the production process. Heating in a sealed tank avoids the aging of asphalt due to long-term high-temperature heating and exposure to the air. The sulfide produced during the production process is quite limited, reducing environmental pollution.
3. Modifier air delivery or spiral addition system: The modifier manually poured into the pouring hopper is delivered to the asphalt batching tank by wind or spiral. It can be equipped with a metering system.
4. Stabilizer automatic or manual addition system: It can be equipped with a metering system.

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.

Bitumen emulsifier is a surfactant. A surfactant is a compound that reduces the surface tension between two liquids, a gas and a liquid, or a solid and a liquid. Surfactants are mainly used in: detergents, detergents, fabric softeners, wetting agents, emulsifiers, foaming agents, dispersants, adhesives, etc.

Working conditions of asphalt debarreling equipment:
(1) Outdoor temperature: 20°C (average temperature of day and night)
(2) Heat exchange oil: 320 ℃
(3) Loading time is not included (because the personnel equipped in each unit are different, so the loading time is also different)
(4) There is no fluctuation in oil temperature (optimal automatic burner)
(5) The working temperature of the oil furnace is 220-260 ℃
(6) The flow rate of the oil circulation pump is not less than 50m3/h traffic
(7) When the outdoor temperature is lower than 20℃, the output decreases. The lower the temperature, the lower the output, and the higher the temperature, the higher the output.
(8) The greater the deformation of the asphalt barrel, the greater the impact on the output

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.

We should select products that meet the specifications, and we should not select raw materials that do not meet the specifications. The other thing is the operation technology of asphalt heating equipment. Skilled operation technology is the most important, and training is required before taking up the post.
In recent years, with the continuous development of various industries, the production of various equipment including modified asphalt equipment has been further developed and applied. Professionals introduced that in the process of using modified asphalt equipment for production, the terminal control system implements full automatic control of medium weight, working temperature, working flow, valve opening and closing, etc., thereby ensuring the quality of modified asphalt and greatly improving production efficiency. Now Shandong Duxiu Factory will explain the operating advantages of modified asphalt equipment to customers:
The base asphalt is heated to 150-170℃ in the rapid heating tank and then enters the blending tank to mix with the modifier fed in through the feeding device. The asphalt pump at the bottom of the blending tank then sends it to the colloid mill for high-speed grinding and shearing, so that the modifier and base asphalt are fully dissolved in extremely small particles, thereby improving the various properties of the asphalt. The finished modified asphalt after high-speed shearing and grinding enters the finished product development tank at the rear for direct use.

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:

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.

Asphalt spreading truck is a kind of black ground construction machinery. It is an important equipment in the logistics construction of roads, municipal roads, airports and ports.

In short, the cold patching process has occupied a place in the field of rapid repair of asphalt pavement with its unique advantages and has become an indispensable part of modern highway maintenance.

No matter what product is used, after using it for a period of time, some large and small problems will inevitably arise, which will affect our work, just like the use of asphalt heating equipment will cause problems such as uneven asphalt pavement. We know that for the use of asphalt heating equipment, the construction of asphalt pavement is affected by many factors, including the quality of construction personnel, the quality of roadbed construction, the treatment of the two sections of the bridgehead culvert and the expansion joint of the bridge, the construction of the road subbase and base, the selection of road construction machinery and the quality of road materials. These are the main reasons affecting the flatness of the road surface.
In order to better help customers apply it, professionals introduce the use of asphalt heating equipment. Flatness is an important indicator for measuring the quality of high-grade pavement. Unsmooth pavement will increase driving resistance and cause additional vibrations in the vehicle, which will directly affect the safety and comfort of driving. At the same time, it will aggravate the damage of automobile parts and tires and increase fuel consumption.

Regarding the basic knowledge of modified bitumen plant, I believe that many consumers have already had a basic understanding of it. Because of the continuous development of various fields today, various facilities including modified bitumen plants have been well developed and applied, and modified bitumen plant has gradually been recognized by customers.
The direct quick heating portable equipment in the modified bitumen equipment not only has a faster heating speed, saves fuel, and is pollution-free, but also convenient and easy to operate. The automatic heating system completely eliminates the trouble of baking or cleaning bitumen and pipelines.

Fillers used in emulsion bitumen equipment are generally divided into two types: chemically active and non-chemically active. In the production of emulsion bitumen equipment, it can improve the stability of the slurry mixture, speed up or slow down the demulsification speed, and improve the strength of the sealing layer. When adding chemically active fillers, the reaction and compatibility of the fillers with mineral materials and modified emulsion bitumen should be fully considered.
