An emulsifier, an emulsifier, is used to emulsify an emulsified material into an emulsified medium. The emulsifier is also an external active agent and is an emulsion stabilizer. When we scatter the emulsifier to the appearance of the smashed material, it will form a thin film or electric double layer, so that the sag phase has a charge, which can prevent the small droplets of the 涣 phase from condensing with each other, so that the emulsion formed Relatively stable.
The coating is composed of a film-forming substance, a pigment filler, a solvent, and a coating aid additive. In the meantime, the auxiliaries we call are the external active agents, which are widely used in the guessing.
If it is necessary to stabilize the pigment in the system, it is necessary to participate in a certain amount of the surfactant of the branched molecule. In addition, because the external tension of the system is reduced, bubbles are likely to occur when the mixture is dispersed, so it is necessary to participate in a certain amount of defoaming agent to defoam and suppress foam. In addition, in the production process of some water-based coating film-forming substance emulsions, we also need to participate in a certain amount of emulsifier to make the emulsion stable.
