Emulsified asphalt equipment

With the widespread promotion and application of slurry sealing technology in emulsified asphalt equipment in China, higher requirements have been put forward for the quality and output of emulsified asphalt, and the emulsified asphalt equipment is developing towards standardization and rationalization.

The production of emulsified asphalt equipment can increasingly bring benefits to road construction. The application of emulsified asphalt equipment is becoming more and more widespread, evolving from the traditional sprayed primer to the new micro-surfacing modified emulsified asphalt. In addition, some emulsified asphalt equipment combines asphalt extraction equipment with local heating technology. This not only enables the rapid production of a large amount of finished asphalt but also meets the requirements for small-batch production of high-temperature asphalt. It not only solves the problem of difficult extraction of asphalt in large storage tanks but also directly produces high-temperature asphalt.

In many places, we can see emulsified asphalt equipment. Emulsified asphalt equipment is a mechanical device used to melt asphalt and, through mechanical shearing, disperse it in the form of fine droplets in an aqueous solution containing emulsifiers, forming an oil-in-water asphalt emulsion. The production feature of emulsified asphalt equipment is that under the action of emulsifiers, asphalt is broken into tiny particles through mechanical force and evenly dispersed in water to form a stable emulsion, that is, emulsified asphalt.

Emulsified asphalt is an asphalt emulsion formed by melting asphalt and then dispersing it in a certain amount of water in the form of fine droplets through the action of emulsifiers and machinery. According to the type of charge, it can be classified into: cationic type, anionic type and nonionic type. According to the demulsification speed, it can be classified into: fast-breaking type, medium-breaking type and slow-breaking type. According to the construction party. The methods can be classified into: sprinkling type and mixing type. To enhance the performance of emulsified asphalt (such as high-temperature stability, low-temperature resistance, etc.), modifiers (generally rubber emulsions, with SBR latex being the most commonly used at present) need to be added to the emulsified asphalt, and then emulsified modified asphalt is produced through equipment. Solid content of emulsified asphalt: ≤ 50%
