application:
1Paper making
PVA has big adhesive strength, film forming flexile, use it to replace starch and casein or use with them, conduct as coating vehicle or used as jelly to make top sizing to artpaper, surface-resistance paper, blue-print base paper, kraft paper.
2.Adhesives
based adhesives have good adhesive strength to paper, cloth, wood and widely used. It has good adhesive property, water-solubility, non-toxic, not burn. It has big market in materiall-binded board, leather, decorate industry, etc. it could highen adhesive strength by add some iroganic matter like clay, kentonite, alumina, titanium oxide.
3.Sizing material
based sizing agent is the most efficient synthetic sizing agent and textile processing agent, it has good adhesion property to cotton, linen, polyester, vinylon, adhesive fibers. The serosal is colorless and transparent, toughness, wear-resistant ,sun
resistant and in high mechanical strength. Using it cloth breakage rate can be reduced, due to small amount using of sizing agent, the woven fabrics feel stiff, smooth and delicate, fabric surface is not rough, and increase the number of winding horse, very easy to desizing.
4Raw material of fiber
After washing, solution, spinning processing formal and treating of PVA, it can get vinylon fiber, then blending with feather, cotton, viscose fiber and get article of vinylon, non-woven fabrics, geotextiles, which widely used in apparel, industry use cord thread, fishing net rope, tarpaulin, material of agriculture and health.
5Film
Film made from PVA is in good transparence, high strength of tensile and crack-resistance, good moisture permeability and thermal insulation, fastness to oil and or organic chemicals, so that it used in taxtile packing. It can also used in food packing, non-toxic, odorless, non-pollution. Besides it can be compunded with polyethylene, polypropylene and others to use in instrument packing, printing plate.
