Dispersible emulsion powder is a free flowing powder prepared by spray drying with a special polymer emulsion. It has good redispersibility in water, and can be re-dispersed into a emulsion after encountering water, and the performance of the dispersion liquid is basically the same as the initial emulsion, when the water is evaporated again, it can form a polymer film with high flexibility and cohesiveness. At the same time, the redispersible polymer emulsion powder has good storage stability, can be stored under conventional conditions without adhesion, and can maintain good fluidity.
Redispersible emulsion powder can be pre-mixed with cement, fillers and chemical additives in a certain ratio in the factory, and then packaged into products for sale. On-site water mixing can be used, eliminating the tedious on-site measurement and mixing process, which is conducive to reducing dust pollution, improving construction quality and shortening project cycle, thus achieving large-scale application in the construction industry.
