The redispersible emulsion powder is first physically mixed with other inorganic cementing materials (such as cement, hydrated lime, etc.) and various aggregates and additives to make dry mixed mortar. When the dry mixed mortar is mixed with water, under the action of hydrophilic protective colloid (polyvinyl alcohol) and mechanical shear force, the rubber powder particles are dispersed into the water, and affect the rheology, constructability, compressive bending strength and tensile bond strength of the mortar.   Ceramic tile binder is the cement-based bonding material of ceramic tile, which can be used to paste natural stone such as ceramic tile, polished brick and granite. The addition of redispersible emulsion powder can extend the working time and adjust the time of the newly mixed mortar, improve the water retention performance and anti-hanging performance; Improve the bonding property, deformation resistance and aging resistance of hardened mortar.   External wall insulation system has been applied in the field of the world, and its installation on the external wall of the building mainly saves the energy consumption of the building 40%-70%. Dry mix mortar modified with redispersing emulsion powder is used to bond polystyrene board to the wall while protecting the polystyrene board. For protective mortars as well as cement-based decorative mortars, polymer adhesive powder provides good adhesion, impact resistance, low water absorption and high flexibility even in harsh environments.   After film formation, the emulsion and redispersed emulsion powder can form high tensile strength and bond strength on different materials, and they are combined with cement as the second binder in the mortar, and the cement and polymer play the corresponding special features respectively, so that the performance of the mortar can be improved.   Even if the type of emulsion powder copolymer is the same, due to the different production processes of different manufacturers, the properties of latex powder are different, and its properties in the corresponding mortar should be considered comprehensively when selecting rubber powder. With the increase of the national promotion of the use of dry mixed mortar, the demand for redispersible emulsion powder is showing a rapid growth momentum, which is bound to usher in a new peak of use.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com ElephChem Holding Limited, professional market expert in Polyvinyl Alcohol(PVA) and Vinyl Acetate–ethylene Copolymer Emulsion(VAE) with strong recognition and excellent plant facilities of international standards.
