Application and advantage
(1) Building adhesive. The application in the construction industry mainly includes mortar adhesive, putty adhesive, and coating adhesive.
(2) Textile pulp. Mainly used for sizing pure polyester or polyester cotton yarn, it has good adhesion and film forming properties, but for high count pure cotton yarn, it also requires a mixture of PVA and acrylic size.
(3) Adhesive. In addition to building adhesives, PVA can also be used in conjunction with other chemical raw materials to produce various types of adhesives, or as a protective colloid to produce white latex. It is mainly used for paper, wood, textiles, office adhesives, and high-end coating substrates.
(4) Fiber. Vinylon fiber is a Synthetic fiber made from PVA, including vinylon staple fiber, vinylon staple fiber, high strength high modulus, medium strength medium modulus, water-soluble fiber, etc. Among them, high-strength and high modulus fibers have high strength and modulus, and are widely used in building materials, rubber products, coated fabrics, plastic hoses, and other industries that require higher strength industrial wires, especially in cement and building materials.
(5) Polyvinyl butyral (PVB). PVB film is mainly used as an intermediate film for glass. PVB Laminated glass has excellent properties such as safety, heat preservation, noise control and UV isolation. It is widely used in building safety glass, automobile windshield, military Bulletproof glass used in aircraft, tanks, warships, etc., as well as solar cells and solar receivers.
(6) Paper making. Mainly used as a surface sizing agent, pigment binder, and beater additive for paper, it can improve the wear resistance, folding resistance, tear resistance, glossiness, smoothness, and printing adaptability of paper.
(7) Biodegradable PVA film. Water soluble PVA film is a new type of plastic product that has emerged internationally. It utilizes the film-forming properties, water and biological degradation characteristics of PVA, and can be completely degraded into CO2 and H2O. It is truly a green, high-tech, and environmentally friendly packaging material.
