hydroxypropyl methylcellulose HPMC in Plastering MortarFebruary 2nd 2023
Latex powder is an important additive in dry mortar. It can not only improve the elasticity, bending strength and flexural strength of the material. What is the role of latex powder in dry mortar? The following mortar powder manufacturers will introduce.
1. Masonry mortar, plastering mortar
Redispersible latex powder has good impermeability, water retention, frost resistance, and high bonding strength, which can effectively solve the quality problems such as cracking and penetration between traditional masonry mortar masonry.
2. Self-leveling mortar, floor material
Redispersible latex powder has high strength, good cohesion/adhesion and required flexibility. It can improve the adhesion, wear resistance and water retention of the materials. It can bring excellent rheology, workability and the best self-smoothing performance to the ground self-leveling mortar and leveling mortar.
3. Tile adhesive, tile jointing agent
Redispersible latex powder has good cohesiveness, better water retention, long open time, flexibility, anti-sagging performance and good freeze-thaw cycle resistance. It can bring high cohesiveness, high slip resistance and good construction operability to tile adhesives, thin-layer tile adhesives and joint fillers.
4. Waterproof mortar
Redispersible latex powder enhances the bonding strength to all substrates, reduces elastic modulus, increases water retention, and reduces water penetration. It provides products with high flexibility, high weather resistance and high water resistance requirements, and provides hydrophobicity The long-lasting effect of the sealing system required by water resistance.
5. External thermal insulation mortar
Redispersible latex powder in the external wall insulation system enhances the cohesion of the mortar and the binding force to the insulation board, and reduces energy consumption while seeking insulation. In the external wall thermal insulation mortar products achieve the necessary workability, flexural strength and flexibility, which can make your mortar products have good bonding properties with a series of thermal insulation materials and base layers. At the same time, it also helps to improve impact resistance and surface cracking resistance.
6. Repair mortar
Redispersible latex powder has the required flexibility, shrinkage, high cohesiveness, suitable flexural and tensile strength. The repair mortar meets the above requirements and is used for the repair of structural and non-structural concrete.
7. Interface mortar
Redispersible latex powder is mainly used to treat the surface of concrete, aerated concrete, lime-sand brick and fly ash brick, etc., to solve the problem that the interface is not easy to bond, the plaster layer is hollow, cracked, etc. due to excessive water absorption or smoothness of these surfaces. Problems such as peeling. It makes the adhesion stronger, is not easy to fall off and is resistant to water, and has excellent freeze-thaw resistance, which has a significant effect on simple operation and convenient construction.
