Emulsified asphalt production equipment can be made anionic emulsified asphalt, cationic emulsified asphalt and adhesive type emulsified asphalt. Road maintenance operations commonly used in the first two. Which emulsified asphalt is selected? This should be carried out according to actual needs.
Cationic emulsified asphalt on the climate of low sensitivity, by chemical demulsification, its performance is relatively stable, long-term storage will not break the milk, but cationic emulsified asphalt transport more dangerous, it should pay attention to cationic emulsified asphalt storage process safety, strict compliance with storage rules The
Cationic emulsified asphalt is suitable for aggregate, including silica aggregate. If the stone is clean, the cationic emulsified asphalt does not need to be pretreated during construction.
Therefore, in the areas of high reliability requirements, and has the correct handling of the venue, the use of cationic emulsified asphalt is more appropriate. Demulsification is an important concept of emulsified asphalt blends. Over the years, the Asphalt Research Center has been studying the mechanism of accelerating demulsification, especially the Emulcol Research Center in Europe and the Development Research Center of SAMI and Emoleum, Australia. Most systems use PH as a demulsifier to control cationic emulsions. In fact, the chemical molecular structure of the material is different and the demulsification rate is different. Emulsification Demulsification requires particle aggregation, the presence of gravity between the particles to overcome the repulsive force. In this evolution process, the particles are getting bigger and bigger. Usually the demulsification process is divided into two steps, namely flocculation and agglomeration.
