Supply Jiangsu Taizhou redispersible powder price, good water retention VAE powder history of the development of Xinjiang Su Nuoke Cotton Co., Ltd. manufacturers of dispersible polymer powders, low ash, the film is good, has reached the quality of imports. We China factory direct, free samples and technical guidance, please call us! redispersible powder is made from a vinyl acetate and vinyl versatate -VeoVa or vinyl or acrylate binary or ternary copolymers through Modified emulsion powder obtained by spray drying, it has good dispersibility can be further re-dispersed into contact with the aqueous emulsion, and its chemical properties are identical with the initial emulsion. Historical re-dispersible polymer powders development: re-dispersible polymer powders study began in 1934 polyvinyl acetate Germany IGFarbenindus AC's re-dispersible polymer powders and powder latex Japan. After World War II a serious lack of labor and construction resources, forcing Europe, especially Germany, using a variety of building materials to improve construction efficiency of powder, the late 1950s, Germany's Hoechst and Wacker Chemical Corporation began re-dispersible polymer powders industrialization produce. At the time, re-dispersible polymer powders are mainly for polyvinyl acetate type, mainly for wood glue, wall primer and cement walls and other materials. However, due to the minimum film-forming temperature PVAc powder high, poor water resistance, alkali resistance and poor performance limitations of its use are subject to greater restrictions. As industrialization success VAE emulsion and VA / VeoVa emulsion on the 1960s, the minimum film-forming temperature is 0 ℃, has good water resistance and alkali resistance dispersible polymer powders have been developed, after its application has been widely promoted in Europe, the scope of use is gradually extended to a variety of structural and non-structural construction adhesives, modified dry-mix mortar, wall insulation and finish systems, wall smooth plastic and seal gray paste, powder coatings, construction putty fields. Redispersible powder consisting of: * redispersible powders usually white powder, but there are a few other colors. * Polymer resin: Located in the core of the powder particles, but also can play a role in re-dispersible polymer powders main ingredient. * Additives (inner): together with a resin modified resin acts. * Additives (outside): To further expand the re-dispersible polymer powders yet another performance to add material. * Protective colloid: In redispersible powder particle surface layer of hydrophilic material wrapped, the vast majority of dispersible polymer powders protective colloid is polyvinyl alcohol. * Anti-caking agents: fine mineral filler, primarily used to prevent caking powder and to facilitate the flow of powder (poured out from a paper bag or a tanker) two in the storage and transportation process, the role of re-dispersible polymer powders: * Can redispersible latex powder dispersed after deposition and enhance the role play as a second adhesive; * protective colloid is absorbed mortar system (after the film will not be destroyed water, or "secondary dispersion"; * film-forming polymer resin as a reinforcing material distributed to the entire mortar system, thereby increasing the cohesion of the mortar; Nock redispersible latex powder mainly used: wall putty powder, tile adhesives, tile grouts, dry interface agent, wall exterior insulation mortar, self-leveling mortar, repair mortar, decorative mortar, waterproof exterior insulation mortar dry mix mortar in mortar is to make traditional cement mortar brittle, high elastic modulus and other weaknesses to improve, confers cement mortar good flexibility and tensile bond strength to resist and delay the generation of cracks cement mortar, the mortar is formed between the polymer and the interpenetrating network structure, a continuous polymer film is formed in the pores to enhance the aggregate bond, blocking part of the pores within the mortar, so the modified mortar hardened cement mortar than the greatly improved performance. welcome to the building materials industry friends to inquire! 苏诺克 willing to work with you hand in hand!
