To adjust the pH value of the use of asphalt emulsifier, because the pH often have an impact on the performance of emulsifying properties and latex, which is determined by the nature of the emulsifier. Different types of emulsifiers for type of acid added, the amount and purpose of the acid addition of acid is also different. Amine emulsifier must be added to the preparation of an aqueous acid amine salt formulations to produce asphalt emulsifier can be dissolved in water emulsion play, so appropriately with acid to adjust the pH range to become amine salt emulsifier solution. Adding an excess of emulsifier in the emulsifier aqueous solution, it can be formed not only adsorbed monomolecular film oriented, and capable of forming a complex multi-layer film and the emulsifier molecules adsorbed cluster asphalt emulsifier, to try to keep a minimum free energy. If the pitch was subjected to high shear into small particles (0.01mm-0.001mm) molecules and uniform emulsion dispersed in water, the water is immediately dissolved in the asphalt particles are adsorbed interface, resulting in a new arrangement of adsorption, a lipophilic group some asphalt emulsifier adsorbed on the internal supply of asphalt, the water adsorbed on the hydrophilic group at one end, is fixed to the interface in order to clamp the asphalt emulsifier, which reduces the interfacial tension of bitumen and water. When the emulsifier adsorbed molecules reaches saturation, the surface layer of asphalt particles encapsulated emulsifier molecule has a certain mechanical strength strong molecular film, so that the asphalt particles hydrophilic, stably and uniformly dispersed in water formed emulsified asphalt.
