The use of redispersible latex powder in construction is relatively common, and sometimes cracking occurs. If this problem occurs, how should we deal with it? The following mortar powder manufacturers will introduce it in detail.
The film of the product is elastic and tough, and it is in the rigid skeleton formed after the cement mortar is hydrated. Between the cement mortar particles and the particles, it functions as 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 resins. It is a soft film coated on the surface of mortar particles, and the redispersible latex powder can absorb the impact of external force, relax without breaking, thereby improving the impact resistance of mortar. Redispersible latex powder improves hydrophobicity, reduces water absorption, and can improve the microstructure of cement mortar.
Its polymer forms an irreversible network during cement hydration, adding redispersible latex powder. Close 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 durability.
The role of cement dry powder mortar is remarkable, which can improve the bonding strength and cohesion of materials, improve the elastic bending strength and flexural strength of materials, improve the freeze-thaw resistance of materials, and improve the weather resistance, durability and wear resistance of materials. Improve the hydrophobicity of the material, reduce the water absorption rate, improve the workability, reduce the shrinkage rate of the material, effectively prevent cracking, and improve the bending and tensile properties.
