The content of redispersible polymer powder
November 25th 2024Redispersible latex powder is commonly used in building construction, and sometimes it will encounter cracking. If this problem occurs, how should we deal with it? The following mortar powder manufacturer will give a specific introduction. The film of the product is elastic and tough, in the rigid framework formed by the hydration of the cement mortar. Between cement mortar particles and particles, it has a function similar to a movable joint, which can withstand high deformation loads, reduce stress, and improve tensile and bending resistance. Redispersible latex powder improves impact resistance for thermoplastic resin. It is coated with a soft film on the surface of the mortar particles, and the redispersible latex powder can absorb the impact of external force, relax without being damaged, thereby improving the impact resistance of the mortar. Redispersible latex powder improves water repellency, reduces water absorption, and improves the microstructure of cement mortar. Its polymer forms an irreversible network during the cement hydration process, and redispersible latex powder is added. Seal the capillary in the cement gel, block the absorption of water, prevent the penetration of water, and improve the impermeability. Redispersible latex powder improves abrasion resistance and durability. Cement dry powder mortar has a significant effect, which can improve the bonding strength and cohesion of the material, increase the elastic bending strength and flexural strength of the material, improve the freeze-thaw resistance of the material, and improve the weather resistance, durability and abrasion resistance of the material. Improve the hydrophobicity of the material, reduce the water absorption, improve the workability, reduce the shrinkage of the material, and effectively prevent cracking. , Improve bending and tensile resistance.
