The application of dispersible emulsion powder

April 2, 2022by admin0

The dispersible emulsion powder is dispersed and molded in the mold as a second binder to enhance the adhesion; the protective colloid is absorbed by the mortar system (it will not be destroyed after the mold is molded. or secondary dispersion); the molded polymer resin is distributed throughout the mortar system as a reinforcing material, thus increasing the cohesiveness of the mortar.

VAE Powder

What is the role of redispersible emulsion powder in wet mortar ?
A: Improving construction performance; improving fluidity; increasing thixotropy and anti-sagging; improving cohesion; extending opening time; enhancing water retention.

What is the function of redispersible emulsion powder in mortar after curing?
A: Increase tensile strength; increase flexural strength; reduce modulus of elasticity; increase deformability, material denseness, abrasion resistance, cohesive strength; reduce carbonation depth; reduce material water absorption; make the material have excellent water repellency (add water repellency powder).
