1 Improve the bending strength and flexural strength of mortar
The polymer film formed by the redispersible latex powder has good flexibility. Forming a film in the gap and surface of the cement mortar particles to form a flexible joint. Thereby, the brittle hard cement mortar becomes elastic. The mortar to which the redispersible latex powder is added is several times higher than the ordinary mortar in the tensile bending resistance.
2 Improve the bonding strength and cohesion of mortar
After the film of the dispersible polymer powder as an organic binder is formed, high tensile strength and bonding strength can be formed on different substrates. It plays an important role in the adhesion of mortar to organic materials (EPS, extruded plastic foam board) and smooth surface substrates. The film-forming polymer rubber powder is distributed as a reinforcing material throughout the mortar system to increase the cohesion of the mortar.
3 Improve the impact resistance, durability and wear resistance of mortar
The rubber powder particles fill the pores of the mortar, and the compactness of the mortar is increased to improve the wear resistance. Under the action of external force, it will produce slack without being destroyed. The polymer film can be permanently present in the mortar system.
4 Improve weather resistance of mortar, freeze-thaw resistance, prevent mortar cracking
The redispersible latex powder is a thermoplastic resin with good flexibility, which can make the mortar respond to external hot and cold environment changes, effectively preventing the mortar from cracking due to the temperature difference.
5 Improve the water repellency of mortar and reduce water absorption
The dispersible polymer powder forms a film on the pores and surfaces of the mortar. The polymer film does not disperse twice after being exposed to water, preventing the intrusion of moisture and improving the impermeability. Special dispersible polymer powder with hydrophobic effect, better water repellency.
6 Improve mortar construction workability
There is a lubricating effect between the particles of the polymer rubber powder so that the mortar components can flow separately, and the rubber powder has an inducing effect on the air, giving the compressibility of the mortar and improving the workability of the mortar.
