The role of redispersible latex powder in the construction industry cannot be underestimated. As the most widely used additive material, it can be said that the appearance of dispersible latex powder has raised the quality of construction by more than one level. The main component of latex powder is an organic macromolecular polymer with relatively stable properties. At the same time, PVA is added as a protective colloid. It is generally powdery at room temperature. The adhesion ability is very strong and the construction performance is also very good. In addition, this latex powder can significantly improve the wear resistance and water absorption performance of the wall by enhancing the cohesive force of the mortar. At the same time, the cohesive strength and deformability are also certain. degree of improvement.
The role of redispersible latex powder in wet mortar:
(1) Enhance the water retention of mortar;
(2) Extend the opening time of mortar;
(3) Improve the cohesion of mortar;
(4) Increase the thixotropy and sag resistance of mortar;
(5) Improve the fluidity of mortar;
(6) Improve construction performance.
The role of redispersible latex powder after the mortar is cured:
(1) Enhance the bending strength;
(2) Improve tensile strength;
(3) Increased variability;
(4) Reduce the modulus of elasticity;
(5) Improve the cohesive strength;
(6) Reduce carbonization depth;
(7) Increase material density;
(8) Improve wear resistance;
(9) Reduce the water absorption of the material;
(10) Make the material have excellent water repellency.
