General introductions-polyvinyl alcohol 1788/2488/1799/2499 PVA
Polyvinyl alcohol (PVA) is a kind of heavy polymer. It is usually a white or slight yellow floccules,flake,granular or powder in apperance. PVA is non-toxic,insipid and non-polluting. PVA is a kind of water-soluble resin with good chemical stability.It also has good adhesion,film-forming ability, insulation, oil resistance, abrasion resistance and gas berrier properties, and has typical chemical properties of polyols and can make esterification,etherification, acetalization reactions. The PVA normally come from the side products of petrolium production. The biggest two manufacturers of petrolium products are China Petroleum and Sinopec. Henan Ant Construction is one of major polyvinyl alcohol PVA powder factory manufacturer in China, it's raw materials are always choose from top granding producer of Sinopec.
Application field-polyvinyl alcohol 1788/2488/1799/2499 PVA
Polyvinyl alcohol (PVA) usually used into the Textile industry,construction and decoration industries,chemical industry, pape-rmaking,agriculture, petroleum exploitation, and also cosmetics,pharmaceuticals,printing,ceramics,steel,electronics,electroplating, and so on.
Today we shipped Polyvinyl alcohol (PVA) for our Russia customer is mainly used as fluid loss agent additive in oil well industry. Polyvinyl alcohol (PVA) is mainly used together with nonionic and anionic monomers for producing fluid loss agent. Comonomers include nonionic and anionic monomers. Non-ionic monomers mainly include: AM (acrylamide), NVP (N-vinylpyrrolidone), NNDMA (N, N-dimethylacrylamide), St (styrene), VI (ethyleneimidazole), VFA (ethylene Formamide), VP (vinylpyridine), VMAA (N-methyl-N-vinylacetamide), etc. Among these monomers, AM is easily hydrolyzed, so the content in the copolymer should not be too much; NNDMA introduces non-hydrolyzable groups and is resistant to high temperatures
Anionic monomers mainly include two types: one is sulfonate monomer, such as AMPS (2-acrylamido-2-methylpropanesulfonic acid), SS (styrene sulfonate), VS (ethylene sulfonate ), PS (propylene sulfonate); the other is a carboxylate monomer, such as AA (acrylic acid), MAA (methacrylic acid), HEA (hydroxyethyl acrylic acid), IA (itaconic acid) and so on. AMPS has strong temperature and salt resistance, high polymerization activity, and is increasingly widely used. Large-scale production has been formed in China.
Henan Ant Constructions is one of the earliest producer of kinds of dry mortar and wall putty powder in China. Therefore, it gone through the whole history of mortar and wall putty application in China and summerized rich experiences in improving mortar and putty powder formula and solutions for kinds of problems during application, such as cracking, falling off after drying, adhesive strength, thermal insulation, water retention, etc.
Henan Ant Constructions design suitable formula according to your local materials feature and also provide kinds of suitable chemical additives, cooperated lab for making different testing of additives and finished mortar is available too.
