The so-called emulsified asphalt is the thermal melting of asphalt. Through the action of emulsifiers and machinery, the asphalt is dispersed in an aqueous solution containing a certain amount of emulsifier in fine droplets to form an asphalt emulsion in water and oil. This emulsion is dry liquid at room temperature. Modified emulsified asphalt refers to the use of emulsified asphalt as the base material and the asphalt modified material as the modified material. Under a certain process flow, it is blended, mixed and prepared into a modified asphalt mixed emulsion with certain characteristics. This kind of mixed emulsion is called modified emulsified asphalt. The modified production process of emulsified asphalt can be divided into four categories: 1. Emulsified asphalt is mixed with latex modifiers, that is, emulsified and then modified; 2. Mix latex modifiers into an aqueous emulsifier solution, and then enter colloidal grinding with asphalt to make modified emulsified asphalt; 3. Put latex modifier, emulsifier aqueous solution and asphalt into colloid at the same time Grinding to make modified emulsified asphalt (2, 3 two methods can be collectively referred to as edge (Emulsification edge modification); 4. Emulsify the modified asphalt to make the emulsified modified asphalt. Qianyu Wangpu https://29880.qianyuwang.com/
