Production method of Polyvinyl Alcohol Fiber The average molecular weight of polyvinyl alcohol, the raw material used in Polyvinyl Alcohol Fiber, is 60,000 to 150,000, with a thermal decomposition temperature of 200 to 220℃ and a melting point of 225 to 230℃. Polyvinyl alcohol fiber can be produced by wet spinning and dry spinning. The heat-treated Polyvinyl Alcohol Fiber can be acetalized to polyvinyl alcohol formaldehyde fiber. The process of acetalization is the process of washing the tow to...

Introduction of Polypropylene Fiber Polypropylene Fiber is pure polypropylene as raw material, through a unique process and equipment, after melting - extrusion - stretching - surface treatment - cutting and other processes refined, it has outstanding tensile strength and good dispersion, can be three-dimensional chaotic three-dimensional distribution in the concrete, so as to play a role in the concrete to resist cracking and pulling attached. Anti-crack fiber is a kind of anti-crack fiber...
Application of the product Polyvinyl Alcohol Fiber are used as additives in concrete due to their hydrophilicity, high strength, good dispersibility and corrosion resistance. Polyvinyl Alcohol Fiber concrete can be used for organic synthetic fiber concrete. Polyvinyl alcohol is hydrolyzed from polyvinyl acetate under acid or alkali conditions, commercial polyvinyl alcohol fibers are Kuralon, Vinylo, etc.. Polyvinyl Alcohol Fiber has the advantages of high specific surface area, high ultimate...
Introduction of this product Polypropylene Fiber, also known as polypropylene, polypropylene fiber with propylene polymerization technology made of isotactic polypropylene as raw materials, after a special process made of synthetic fibers. The main advantages of Polypropylene Fiber are： （1）Polypropylene Fiber has high strength, good elasticity, wear-resistant, corrosion-resistant:Polypropylene Fiber has high strength (the same strength in dry/wet state), the strength can reach the strength of...
Various types of Polypropylene Fiber uses (1) Polypropylene fibers made of woven bags to widely replace the jute woven sacks, food, industrial raw materials, fertilizers, food, mineral ores and coal, etc., the most important basic packaging materials, the form has long been by the traditional pillow-type ladder to the barrel, column type and other diversified development. Because of its low density, light weight, with the shape, easy to store, and even replace some of the small containers. (2)...
Introduction of the product Polypropylene fibers are synthetic fibers spun from isotactic polypropylene obtained by polymerization of propylene, also known as polypropylene.In addition, polypropylene fibers can be divided into long fibers, short fibers, spunbond nonwoven fabrics, meltblown nonwoven fabrics and so on. Polypropylene Fiber and cement matrix want to composite the main purpose is to overcome the weakness of the cement matrix, Polypropylene Fiber in the composite material is mainly...
