SVW flocculent JF-221 polyvinyl 2299

SVW flocculent polyvinyl JF-221 (2299) uses 1, vinylon ingredients: polyvinyl alcohol was dissolved after spinning, and then by acetalizing polyvinyl alcohol fiber can be obtained, it can be used with cotton, wool, viscose plastic fibers, blends prepared vinylon textile, widely used clothing, tarpaulins, cords, fishing nets ropes. In general, choose an average degree of polymerization 1750 ± 50 namely PVA17-99 as spinning materials as well. 2, warp slurry: a, polyvinyl alcohol-based modulation of slurry, cotton, linen, polyester, polyvinyl alcohol viscose fibers have good adhesion, smooth and clean after the film, both strong and resistant, promote suitability of warp knitting, weaving reduce friction process due to warp, bend. Stretching warp breakage caused by intense exercise, reduce breakage rate cloth. And weave fabric feel stiff. Smooth and delicate, the fabric is not rough. b, Polyvinyl alcohol is a water-soluble polymer, pulp, sizing, desizing are very convenient. c, the general election is low average degree of polymerization of polyvinyl alcohol (such as PVA15-99,16-99,17-99) as well slurry. 3, adhesive: a, an aqueous solution of polyvinyl alcohol cellulose-containing materials (such as paper, cloth, wood, etc.) the adhesion is very strong, has the advantage of safe, non-toxic and can be used for laminated cardboard, corrugated cardboard adhesive glue and office. Package weight such as cement, fertilizer, and grain is also used brown paper bag with PVA as a binder. b, polyvinyl acetate homo- or with other vinyl monomers production of emulsion (white glue) good protective colloid and dispersing agents, is essential in the production of white plastic. Generally increased with the degree of polymerization of polyvinyl alcohol, emulsion viscosity increased production. Part alcoholysis polyvinyl alcohol (17-88) and complete alcoholysis polyvinyl alcohol (such as 17-99,19-99, etc.) with the use of multi-use part of the alcoholysis polyvinyl alcohol can increase emulsion stability, complete alcoholysis polyvinyl alcohol may increase the water resistance of the emulsion. 4, paper processing: a, polyvinyl alcohol can be used as paper surface sizing agent in the paper industry, with a good film, high film strength characteristics, improve paper printability, smoothness, abrasion resistance, folding, oil resistance and chemical resistance. Choose an average degree of polymerization of PVA was 1750 ± 50 for paper surface sizing well. b, pigments and processing agents: may increase whiteness and gloss coated paper, printing gloss, bright color, to improve the paper. Selected high average degree of polymerization of polyvinyl alcohol for good. c, internal sizing agents for paper: Paper powdered polyvinyl alcohol is added when beating together with the pulp, paper-making, high paper strength thus obtained. Selected high average degree of polymerization of polyvinyl alcohol for good. 5, polyvinyl alcohol film to the film of the product manufactured, transparency, tensile strength, high rupture strength. Packaging, transportation and storage: 12.5 kg / bag, paper-plastic bag, or may need to packaging. Store in a dry, well-ventilated room at room temperature 5-30 ℃, Shelf life: 5 years
