As we all know, emulsified asphalt will be affected by various factors during use, resulting in instability. Therefore, in order to help everyone use emulsified asphalt better, today the editor of Sinoroader would like to take this opportunity to analyze the effects of emulsification. Factors in asphalt stability.

1. Selection and dosage of stabilizer: Since the traditional stabilizer of emulsified asphalt breaks demulsification quickly, it is difficult to achieve long-term stability. Therefore, the editor of Sinoroader recommends that you use multiple combinations to achieve synergy to solve the problem, but you must ensure that the stabilizer The dosage in the system shall not exceed 3%. 
2. The amount of emulsifier: Generally, within the appropriate amount of emulsified asphalt, the more emulsifier is added, the smaller the particle size of the emulsified asphalt is, and before reaching the appropriate amount, as the amount increases, As the micelle concentration increases, the number of monomer compatibilizers in the micelles increases, the free monomer liquid decreases, and the smaller the monomer droplets become.
3. Storage temperature: Emulsified asphalt is a thermodynamically unstable system. When the internal solution is at high temperature, the movement of particles will accelerate, the probability of collision between particles will increase, part of the emulsion will break, and oil and water will separate.
4. Selection and output of defoaming agent: If too much defoaming agent is added, it will seriously affect the storage stability of emulsified asphalt, and may also cause the product surface to appear honeycomb-like, thereby affecting its dispersion and fluidity.
The above are the four main factors that affect the stability of emulsified asphalt explained by Sinoroader. I hope it can help you use it better. If you have any questions, you can call us for consultation at any time.
