The function of redispersible powder in putty
1. Improve the adhesion and mechanical properties of putty. Redispersible latex powder is a powder binder made by spray drying of special emulsion (high polymer). After contacting with water, the powder can be quickly dispersed into emulsion and has the same properties as the initial emulsion, that is, the film can be formed after evaporation of water. The film has high flexibility, high weatherability and high adhesion to various substrates. In addition, the latex powder with hydrophobicity can make mortar have good waterproof property.
2. Improve the cohesion of putty, excellent resistance, alkali resistance, wear resistance, enhance the bending strength.
3. Improve the waterproof and permeability of putty.
4. Improve the water retention of putty, increase the opening time, improve the workability.
5. Improve the impact resistance and durability of putty.
The function of redispersible powder in mortar
1. Improve the compressive strength and flexural strength of mortar.
2. The addition of Redispersible powder improves the elongation of mortar, thus improving the impact toughness of mortar, and also gives the mortar good stress dispersion effect.
3. The bonding performance of mortar is improved. The bonding mechanism depends on the adsorption and diffusion of macromolecules on the adhesive surface. Meanwhile, the rubber powder has a certain permeability. It can fully infiltrate the surface of the base material together with cellulose ether, so that the surface performance of the base course is close to that of the new plastering, so as to improve the adsorption property and greatly increase its performance.
4. Reduce the elastic modulus of mortar, improve the deformation ability and reduce the cracking phenomenon.
5. Improve the wear resistance of mortar. The improvement of wear resistance is mainly due to the existence of a certain amount of glue on the surface of the mortar. The rubber powder plays a bonding role, and the mesh membrane structure formed by the rubber powder can pass through the holes and cracks in the cement mortar. The adhesion between the base material and the hydration products of cement is improved, so the wear resistance is improved.
6. The mortar is endowed with excellent alkali resistance.
