Due to the good stability of the acrylic acid lotion produced by the acrylic acid lotion supplier, demulsification, deterioration, layering and other problems will not occur in the storage, transportation, processing and high and low temperature conditions, but sometimes the stability of the solution will also be affected. The main factors affecting the stability of the product are as follows:

1. Influence of electrolyte: The stability of acrylic acid lotion is closely related to the electrolyte concentration. When the concentration of electrolyte is too high, the probability of diffusion of heterologous ions to the surface of latex particles is greater, and the number of heterologous ions in the adsorption layer increases. Due to the result of electric neutralization ζ The potential decreases, so the overall potential also decreases, so the stability of lotion decreases.

2. Influence of surfactants and protective colloids: surfactants are divided into three types: anionic, cationic and non-ionic. If the surface of latex particles is negatively charged, several different adsorption modes can appear after the addition of surfactants, which play different roles in stabilizing the lotion; In addition, water-soluble macromolecular chains adsorbed or grafted on the surface of latex particles will also stabilize lotion.

3. Effect of mechanical action: the mechanical stability of the product is an important technical index. The mechanical stirring in the lotion polymerization process, the pumping and transfer in the lotion storage and transportation process, and the mixing and processing in the application process will subject the lotion to various forms of mechanical shear, which will give considerable energy to the latex particles. When this energy exceeds the coalescence activation energy of the lotion, the lotion will lose its stability and coagulate.

4. Influence of freezing and melting: acrylic lotion will freeze at low temperature, and freezing and melting will affect the stability of lotion.
