Redispersible latex powder is a powder dispersion obtained by spray drying of modified polymer emulsion. It has good dispersibility and can be re-emulsified into a stable polymer emulsion after adding water. Its chemical properties are exactly the same as the initial emulsion. Therefore, In order to make it possible to produce high-quality dry-mixed mortar and thereby improve the performance of the mortar, today we will talk about the role and use of redispersible polymer powder.
What are the functions of redispersible latex powder?
Redispersed polymer powder is an indispensable functional additive for mixed mortar, which can improve the performance of mortar and mortar to improve strength, improve the bond strength of mortar and various substrates, to improve mortar property, compressive strength flexibility and deformability, flexural strength, abrasion resistance, toughness, adhesion and water holding capacity, and machinability. In addition, polymer powders with hydrophobicity can have good waterproof mortars.
The redispersibility of mortar in the masonry mortar and plastering process leads to the latex powder having a good impermeability, water retention, frost resistance, and high bonding strength, which can effectively solve the problem of traditional Chinese masonry mortar using masonry rooms. Existing quality management problems such as cracking and penetration.
Self-leveling mortar, redispersed latex powder for flooring materials, high strength, good cohesion/cohesion, and requires flexibility. Improves material adhesion, abrasion resistance and water retention. It can bring excellent rheology, workability and best self-slip properties to ground self-leveling mortar and leveling mortar.
A redispersible latex powder with good adhesion, good water retention, long open time, flexibility, sag resistance, and good freeze-thaw cycle resistance. It can be a thin layer of tile adhesive, tile adhesive and rice grains to bring high adhesion, high resistance and good construction workability.
Redispersible latex powder for waterproof concrete mortar enhances the strength of bonding materials to all different substrates, reduces the dynamic modulus of elasticity of enterprises, increases water retention, and reduces water penetration. Products that provide seals with hydrophobic and waterproof functional requirements for system building lasting effect effects.
External wall thermal insulation mortar can re-disperse latex powder in the external wall thermal insulation system, enhance the cohesion of the mortar and the binding force on the thermal insulation board, and reduce energy consumption while seeking thermal insulation for you. The external wall thermal insulation mortar product achieves the necessary work on the external wall , flexural strength and flexibility, can make your mortar products have good bonding properties with a range of insulation materials and base layers, at the same time, it also helps to mention high impact resistance and surface crack resistance.
Redispersible latex powder for repairing mortar with compliant elasticity, shrinkage, high adhesion, suitable flexural and tensile strength requirements. Meets the above requirements for repair mortars to repair structural and non-structural concrete.
The mortar redispersible latex powder for the interface is mainly used for data processing and surfaces such as concrete, aerated concrete, lime-sand bricks and fly ash bricks. It is not easy to bond, the plastering layer is hollow, cracked, and peeled off. The adhesive force is enhanced, it is not easy to fall off and water resistance, and the freeze-thaw resistance is more excellent, which has a significant effect on the simple operation method and convenient construction management.
Redispersible polymer powder application
Tile adhesive, external wall and external thermal insulation system bonding mortar, external wall external thermal insulation system plastering mortar, tile grout, self-flowing cement mortar, flexible putty for internal and external walls, flexible anti-cracking mortar, rubber powder polystyrene particle thermal insulation mortar dry powder coating.
Precautions for the use of redispersible latex powder:
The redispersible latex powder is not suitable for one-time input, and it is necessary to divide the amount in order to find a suitable amount.
When polypropylene fibers need to be added, they must be dispersed in the cement first, because the fine particles of the cement can eliminate the static electricity of the fibers, so that the polypropylene fibers can be dispersed.
Stir and mix evenly, but the stirring time should not be too long, 15 minutes is appropriate, and sand and cement are easily precipitated and stratified when stirred for a long time.
It is necessary to adjust the dosage of additives and add an appropriate amount of HPMC according to the changes of seasons
Avoid moisture caking of additives or cement.
It is strictly forbidden to mix and use with acidic substances.
It is forbidden to use in construction below 5°C. Low temperature construction will cause the biggest project quality problem, resulting in the non-adhesion of the plastering mortar and the insulation board. This is a project quality problem without a remedial plan in the later stage
