1. Introduction to slow cracking and fast setting SBS modified asphalt emulsifier
Slow cracking and fast setting SBS modified asphalt emulsifier is a type of emulsifier specifically used for producing SBS modified emulsified asphalt. Its main feature is that the demulsification speed is slow, but the solidification speed is fast. This emulsifier can quickly break down the emulsion and form an effective protective layer during the construction process, and also has a fast solidification speed, which can open up traffic in a short period of time. Slow cracking and fast setting SBS modified asphalt emulsifier (LT-CMK5) can be used for SBS modified asphalt emulsification, with superior emulsification performance, good workability, and fast strength improvement. It is suitable for micro surface, slurry sealing, cold filing and cold laying ultra-thin surfaces.
2. Basic functions of slow cracking and fast setting SBS modified asphalt emulsifier
The main function of slow cracking and fast setting SBS modified asphalt emulsifier is to mix SBS modified asphalt with water to form a stable emulsion. In the process of asphalt emulsification, emulsifiers help to disperse asphalt particles in water and maintain a dispersed state, facilitating uniform spraying during construction. Appropriate emulsifiers can ensure that emulsions have good stability, appropriate fluidity, and rapid demulsification, thereby improving construction efficiency and asphalt performance.
3. Advantages and disadvantages of slow cracking and fast setting SBS modified asphalt emulsifier
Advantages: (1) High construction flexibility: Construction can be carried out under humid or low temperature conditions, improving construction flexibility. (2) Environmentally friendly: reduces energy consumption and environmental pollution, which is beneficial for environmental protection. (3) Economy: Reduced construction costs, especially in remote or remote areas.
Disadvantages: (1) High technical requirements: requiring professional construction techniques and equipment. (2) High storage requirements: The storage conditions for emulsified asphalt are relatively strict, and it is necessary to avoid delamination, precipitation, or emulsion breaking.
4. Usage method of slow cracking and fast setting SBS modified asphalt emulsifier
Heat the water to 60-70% C. Add the measured asphalt emulsifier to the water, stir and dissolve the hydrochloric acid to adjust the pH value to 2.0-2.5. Heat the asphalt to 180 ° C to produce emulsified asphalt.
5. Application scope of slow cracking and fast setting SBS modified asphalt emulsifier
