The role of latex powder in dry powder mortar is mainly in the following aspects:
1. Improve the compressive strength and flexural strength of mortar.
2. The addition of latex powder improves the elongation of the mortar and thus improves the impact toughness of the mortar, and also gives the mortar a good stress dispersion effect.
3. Improve the bonding performance of mortar. The bonding mechanism is based on the adsorption and diffusion of macromolecules on the sticky surface. At the same time, the permeability of the rubber powder and cellulose ether fully infiltrate the surface of the base material, so that the surface performance of the base layer and the new plastering is close, thereby improving the adsorption. To greatly increase its performance.
4 Reduce the elastic modulus of mortar, improve the deformation ability and reduce the cracking phenomenon.
Packaging and storage:
It needs to be stored in a cool and dry place. The recommended period of use is twelve months. After opening the bag, please use it as much as possible. Otherwise, the bag mouth must be sealed to avoid absorbing moisture from the air.
