1. What are the functions of redispersible latex powder in mortar?
Answer: The redispersible latex powder is dispersed and formed into a mold and acts as a second adhesive to enhance the adhesion; the protective colloid is absorbed by the mortar system (it will not be destroyed after the mold is formed. Or twice dispersed); the polymerization of the mold As a reinforcing material, the resin is distributed in the entire mortar system, thereby increasing the cohesion of the mortar.
2. What are the functions of redispersible latex powder in wet mortar?
Answer: improve construction performance; improve fluidity; increase thixotropy and sag resistance; improve cohesion; extend open time; enhance water retention;
3. What does the redispersible latex powder do after the mortar is cured?
Answer: increase tensile strength; increase bending strength; reduce elastic modulus; increase deformability; increase material compactness; increase wear resistance; increase cohesive strength; reduce carbonization depth; reduce material water absorption; make material Has excellent hydrophobicity (adding hydrophobic rubber powder).
