Introduction of redispersible latex powder to improve bending and tensile resistance

The film of redispersible latex powder is elastic and tough, and it is in the rigid framework formed by the hydration of 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.

The redispersible latex powder in the mortar is actually waterproof

Redispersible latex powder is a water-soluble white or white flowable powder copolymer of ethylene and vinyl acetate. It uses polyvinyl alcohol as a protective colloid. It is commonly used in cement, gypsum, and mortar. It is redispersible Latex powder has outstanding waterproof performance, good bonding strength,

Which mortar can be used for redispersible latex powder

Bonding mortar: to ensure that the cement mortar will bond the wall and the epoxy wallboard with strong adhesion. Improve the bonding compressive strength.

Plastering mortar: to ensure the impact toughness, crack resistance and impact resistance of the system.

Several simple methods to identify redispersible latex powder

1. Appearance method: Use a glass rod to thinly and evenly cover a small amount of redispersible latex powder on the surface of a clean glass plate. The redispersible latex powder manufacturer places the glass plate on white paper and inspects the particles visually. The appearance of foreign matter and coagulum.

Frequently asked questions about the use of dispersible latex powder

The redispersible latex powder is dispersed and formed into a mold and acts as a second adhesive to enhance the adhesion; the protective colloid is absorbed by the mortar system (it will not be destroyed after the mold is formed. Or twice dispersed); the polymerization of the mold As a reinforcing material, the resin is distributed in the entire mortar system, thereby increasing the cohesion of the mortar.

Can redispersible latex powder improve the bonding strength in putty powder?

In the production of putty powder, we need to use redispersible latex powder. Using these latex powders can increase the bonding strength. We know that if we want to produce high-quality putty powder, the formula must be appropriate, and the additives inside must be used appropriate. We use redispersible latex powder to increase the strength, so how can we ensure this strength?
