Redispersible polymer powder is generally used on the exterior wall of the building with putty powder or other cement mixtures, usually with cement and other mixtures on the inside, and latex powder mixed with putty powder to paint the outside, it gives people a kind of It has a soft feeling, and can fully enhance the adsorption force of the mortar, so that the service life of the outer wall is longer.
Its function is first reflected in the improvement of the adhesion of the mortar, because the latex powder will penetrate into the cement and make it full of moisture, so of course the adhesion ability is better. Many times we have headaches because the cement cannot bond with wood and fiber and other raw materials, but with the redispersible polymer powder, we don't have to worry about everything. We all know that the bending resistance of cement is very poor after hardening, and the addition of latex powder will improve its toughness, so that it can withstand higher deformation pressure. Even the microstructure of the cement concrete will be changed by it. It will block the water absorption of the internal structure and prevent the water from permeating out. Then the anti-permeability ability of the external wall is also improved. There is no need to worry about water seepage inside the house when it is raining. Up.
Redispersible polymer powder is added to the cement, so that the fine cement particles and dust are tightly combined, so the load-bearing capacity of the mortar is naturally improved, and the wear resistance becomes stronger. For exterior walls , Will not easily seep water, dry crack, deformation is the standard of qualified quality. Under normal circumstances, simple concrete exterior walls often have a short service life, and it is easy to crack after a few years. Therefore, latex paint is often added in the construction process in recent years to increase its service life and ensure the residents’ life. Personal and property safety.
So, where can redispersible polymer powder be used? Redispersible polymer powder can be used in the following places: cement-based, gypsum-based, bonding mortar, plastering mortar, waterproof mortar, anti-cracking mortar, decorative mortar, cement mortar, plastering mortar, masonry mortar, grout concrete repair and repair Mortar, batching mortar, floor mortar (self-leveling cement mortar for bottom layer, surface layer, etc.), dry concrete, ground leveling layer, tile bonding, construction adhesive, caulking agent, jointing agent, bonding plaster, stucco Gypsum, interior wall putty, exterior wall putty, diatom mud, waterproof coatings, various coatings,redispersible polymer powder can also be used as plasticizers, tougheners, and
thickeners for inorganic hydraulic materials such as cement and gypsum , Binder, film-forming agent, waterproofing agent.
Redispersible polymer powder has the following characteristics:
1. The redispersible latex powder product is a water-soluble redispersible powder, a copolymer of ethylene and vinyl acetate, with polyvinyl alcohol as a protective colloid.
2. VAE redispersible latex powder has film-forming properties. A 50% aqueous solution will form an emulsion, which will form a plastic-like film after being placed on glass for 24 hours.
3. The formed film has certain flexibility and water resistance. Can reach national standards.
4. The redispersible latex powder has high performance: it has high bonding ability, unique performance and outstanding waterproof performance, good bonding strength, giving the mortar excellent alkali resistance, and can improve the adhesion and flexural strength of the mortar , In addition to plasticity, wear resistance and workability, it has stronger flexibility in anti-cracking mortar.
