What are the characteristics of synthetic resin emulsion?
(1) Synthetic resin emulsion is an environment-friendly product, does not pollute the environment, and does not endanger human health.
(2) The molecular weight of the polymer is as high as hundreds of thousands to millions, and the physical properties are good.
(3) The viscosity of the system is low, and the downstream products are more convenient to use.
(4) The process of particle aggregation, creep and coagulation in the process of forming a coating film, and the mechanism determines that the film forming of the emulsion has a minimum film forming temperature (MFT) characteristic. It also determines that the membrane formed by it is open and has good respiration. Its permeability to the substrate is far less than that of solution polymers.
(5) Emulsion is a quasi-stable system, which needs to be stable under certain conditions, including emulsifier , protective colloid, pH value, temperature, electrolyte and external shear force, etc. Store within a certain period of time, otherwise demulsification may occur.
(6) The difference in the polymerization process will have a significant impact on the performance of the emulsion.
