Bitumen dispersant is a kind of chemical additive used to improve the dispersing performance of bitumen. It can disperse viscous bitumen liquid into tiny particles, making it easier to handle and apply. Asphalt dispersants are usually composed of a variety of chemical components, the main components may include the following:
1. Surfactant: Surfactant is one of the key components of asphalt dispersants. Anionic, non-ionic and cationic Surfactant are commonly used. They can reduce the surface tension of asphalt, increase the dispersion and stability of the role.
2. Dispersant: a dispersant is an ingredient used to promote the dispersion of bitumen particles, helping to disperse bitumen into uniform particles. The choice of dispersant depends on the type of asphalt and the desired dispersing effect.
3. Solvent: A solvent is an auxiliary component of asphalt dispersants used to adjust the concentration of dispersants and Surfactant in order to achieve better dispersion in asphalt. Common solvents include petroleum ether, petroleum ether substances.
4. Additives: additives are some help to improve the dispersion of asphalt ingredients, such as thickeners, antioxidants, preservatives, etc. . These additives can improve the stability and durability of asphalt.
It should be noted that different manufacturers and products may use different formulations and composition combinations, so the specific asphalt dispersant composition will vary. When using asphalt dispersants, they should be operated in accordance with the product specifications and recommendations for use, and in accordance with the relevant safe operating practices.
