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.
The proportion of asphalt emulsifier in emulsified asphalt is very small, but its role is crucial. The proportion in emulsified asphalt is generally between 0.2-2.5%. The function of asphalt emulsifier is to transform asphalt into asphalt emulsion. Asphalt is solid at room temperature and needs to be heated when used. After heating, the temperature is high and the risk factor increases during use. However, asphalt emulsion is liquid at room temperature and can be used directly or by adding water without heating. The function of asphalt emulsifier is to make the application of asphalt simple, convenient, safe and environmentally friendly.
Asphalt emulsifiers can be divided into three types according to their ionic properties: anionic, cationic and nonionic.
Cationic emulsified asphalt has the characteristics of good bonding performance, good compatibility with stone materials, and the stone materials at the construction site do not need to be heated. Most of the asphalt emulsifiers currently used in the highway industry are cationic emulsifiers. According to the different speed and effect of demulsification, it is divided into three types: slow cracking type, medium cracking type and fast cracking type. Slow cracking and slow setting type is mainly used as translucent oil. Slow cracking and fast setting are used for micro-surfacing, slurry sealing, cold regeneration, etc. The uses of medium-crack type and fast-crack type are roughly the same. They are mainly used for the production of bonding materials such as adhesive layer oil, gravel seal layer and waterproof base oil.
In short, the emulsified asphalt is selected according to the use needs, and then the asphalt emulsifier for production is selected. Find answers to your questions! If you still don’t find the answer you need, please call the number on the website!

    Some of the equipment of emulsified modified bitumen equipment are as follows. The specially made bitumen filter can effectively filter the residues and dirt in the high-temperature culture medium bitumen to avoid damage to the subsequent equipment. The emulsified modified bitumen equipment adopts a spiral plate type or a shell and tube heat exchanger to quickly heat the culture medium bitumen through high-temperature heat transfer oil to meet the needs of the production process. The emulsified modified bitumen equipment is heated in the storage tank to prevent the bitumen from aging due to long-term high-temperature heating and exposure to the air. The sulfate generated during the production process of the emulsified modified bitumen equipment is very limited, reducing air pollution.
    The emulsified modified bitumen equipment sends the modified material manually poured into the dumping bin to the bitumen batching tank by wind or spiral. It can be equipped with a metering and calibration system. The emulsified modified bitumen equipment thickener is automatically or manually added. The emulsified modified bitumen equipment can be equipped with a metering and calibration system. Emulsified modified bitumen equipment transportation and metering and calibration system, the emulsified modified bitumen equipment adds the set bitumen amount to the batching tank through the frequency converter and computer interlock. The emulsified modified bitumen equipment and bitumen steam flowmeter use big brand products to ensure the preparation.

    Water is one of the raw materials of the modified asphalt storage tank, and it is distributed in various components of the modified asphalt storage tank equipment. According to the components where water is distributed, the anti-cold measures are explained one by one. The water tank of the modified asphalt storage tank, the water inside the water tank is released through the filter valve. Some instruments of the modified asphalt storage tank do not have a filter valve to save the cost of the equipment. The modified asphalt storage tank can only be drained by loosening the flange bolts at the bottom. The water pump of the modified asphalt storage tank mentioned here includes a hot water pump and a circulating water pump. This type of water pump for the modified asphalt storage tank generally uses a pipeline centrifugal pump. There is a sewage outlet at the bottom of the pipeline centrifugal pump. The modified asphalt storage tank pays attention to the sewage treatment of the sewage outlet at the bottom of the pump. The modified asphalt storage tank emulsion tank generally uses a cone bottom. However, in order to better process the modified asphalt storage tank coefficient, the inlet and outlet are usually not placed at the bottom of the modified asphalt storage tank. Emulsion (mostly water) will remain at the bottom of the tank, and this part of the residual liquid in the modified asphalt storage tank must be discharged through the filter valve at the bottom. Emulsion pump for modified asphalt storage tank There are basically two types of emulsion pumps for modified asphalt storage tank equipment on the market, gear pumps or centrifugal water pumps. Gear pumps can only discharge the liquid inside the pump through the connection flange of the pipeline. The centrifugal water pump for modified asphalt storage tanks uses its own sewage outlet for sewage treatment. The first four items of modified asphalt storage tanks with basic knowledge are basically discharged, and the modified asphalt storage tanks will focus on the latter types. Modified asphalt storage tank colloid mill There will also be residual emulsion or water inside the modified asphalt storage tank colloid mill. The gap between the stator and rotor of the colloid mill is within 1mm. If there is a little residual water in the modified asphalt storage tank, it will cause the accident of frozen modified asphalt storage tank. The residue in the colloid mill can be treated by loosening the connection bolts of the finished product pipeline.
