VAE Re-dispersible Polymer Powder is a white or light-colored polymer powder, which is the main additive for dry-mixed mortars such as cement-based or gypsum-based mortars. Mainstream products include vinyl acetate and ethylene copolymer rubber powder (VAC/E), ethylene, vinyl chloride and vinyl laurate ternary copolymer rubber powder (E/VC/VL), vinyl acetate and ethylene and higher fatty acid vinyl ester terpolymer rubber powder. Yuan copolymer rubber powder (VAC/E/VeoVa).
VAE Re-dispersible Polymer Powder formed polymer film has good flexibility. The film is formed on the gap and surface of cement mortar particles to form a flexible connection. Thus, the brittle cement mortar becomes elastic. Mortar with redispersible emulsion powder is several times higher in tensile resistance than ordinary mortar.
In the context of today's rapid development of building materials technology, a product called VAE Re-dispersible Polymer Powder has become a new focus in the industry because of its unique performance and wide application prospects. This new material not only improves the performance of building materials, but is also highly recognized by the market for its environmentally friendly properties.
VAE Re-dispersible Polymer Powder , as a powder adhesive, is widely used in the construction industry. The quality of dispersible latex powder is directly related to the quality and progress of construction. With the rapid development of the domestic building energy-saving market With the development of VAE Re-dispersible Polymer Powder products, more and more companies have entered into the research and development and production of VAE Re-dispersible Polymer Powder products, and users have more and more choices. However, at the same time, the quality of dispersible latex powder has become mixed, with good and bad mixed. In addition, in order to reduce costs, some manufacturers ignore quality standards and pass off inferior products as high-quality products. Some even pass off fake products as genuine, using general resin powder and selling it at low prices under the guise of redispersible latex powder. This not only disrupts the market but also deceives the market. consumer.
VAE Re-dispersible Polymer Powder is mainly used in dry; Interior and exterior wall putty powder, tile adhesive, tile jointing agent, dry powder interface agent, exterior wall external insulation mortar, self leveling mortar repair mortar, decorative mortar, waterproof mortar external insulation dry mixed mortar.
The VAE Re-dispersible Polymer Powder will disperse in water to form a stable lotion, but the redispersibility of the emulsion powder only occurs once, and the hardened mortar and other materials will not disperse again in water.
The VAE Re-dispersible Polymer Powder is water-soluble redispersible powder, which is divided into ethylene/vinyl acetate copolymer, vinyl acetate/ethylene tert carbonate copolymer, acrylic acid copolymer, etc. The powder adhesive made by spray drying takes polyvinyl alcohol as the protective colloid.
Different quality and different types of redispersible latex powder, even when used in the same purpose, will be added in different amounts. Different uses, using the same brand, the same quality of VAE Re-dispersible Polymer Powder, the amount of addition will be different. VAE Re-dispersible Polymer Powder has a wide range of applications. Let's give some examples of specific dosage.
VAE Re-dispersible Polymer Powder products are water-soluble redispersible powders, which are divided into ethylene/vinyl acetate copolymers, vinyl acetate/ethylene tertiary carbonate copolymers, acrylic acid copolymers, etc. The powder sticky made after spray drying Mixture, using polyvinyl alcohol as protective colloid. This kind of powder can be quickly dispersed into an emulsion after contact with water. Because VAE Re-dispersible Polymer Powder has high bonding ability and unique properties, such as water resistance, construction properties and heat insulation, they are The scope of application is extremely broad.
As the size of the tiles increases, hollowing is more and more likely to occur after laying, and even the accident of the tiles falling off occurs. This problem has a lot to do with the flexibility of the bonding material.
In order to improve the brittleness, high elastic modulus and other weaknesses of traditional cement mortar in mortar, it is usually necessary to add additives such as VAE Re-dispersible Polymer Powder. VAE copolymer rdp can give cement mortar better flexibility and resistance. Tensile bonding strength to resist and delay the occurrence of cracks in cement mortar. Since the polymer and mortar form an interpenetrating network structure, a continuous polymer film is formed in the pores, which strengthens the bonding between aggregates and blocks the mortar. There are some pores inside, so the performance of the hardened modified mortar is greatly improved compared to that of cement mortar.
VAE Re-dispersible Polymer Powder is dispersed in the gypsum slurry and then forms a film, filling the pores of the slurry and intersecting with the gypsum hydration products to form a three-dimensional network structure, making the gypsum structure more dense.
