China Improve Increase Rdp of Mortar

The addition of RDP increases the elongation of the mortar, thereby improving the impact toughness of the mortar, and at the same time endows the mortar with good stress dispersion. 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 rubber powder has a certain permeability, and the surface of the base material is fully infiltrated together with cellulose ether, so that the surface performance of the base layer and the new plastering is close, thereby improving Adsorption, greatly increasing its performance.
Reduce the elastic modulus of mortar, improve the deformation ability and reduce cracking. Improve the wear resistance of mortar. The improvement of wear resistance is mainly due to the presence of a certain amount of rubber powder on the surface of the mortar. The rubber powder plays a role of bonding, and the omentum structure formed by the rubber powder can pass through the holes and cracks in the cement mortar. Improves the bond between the base material and cement hydration products, thereby improving wear resistance. Gives mortar excellent alkali resistance.
