CCP Polyvinyl Alcohol PVA BP-17 For Ceramic Adhesive
Discription:
Polyvinyl alcohol BP-17 powder is especially Used in the manufacture of polyvinyl acetal, gasoline-resistant pipes and vinylon synthetic fibers, fabric treatments, emulsifiers, paper coatings, adhesives, etc.
A water-soluble polyvinyl alcohol fiber and a preparation method thereof are characterized in that 100 parts of polyvinyl alcohol with a degree of polymerization of 500-2000 and an alcoholysis degree of 75-99mol% are mixed with dimethyl sulfoxide/water=90-70: 200~400 parts of mixed solvent of 10~30 ℃, put it into a stainless steel dissolving kettle, dissolve it for 3~4 hours at a temperature of 80-120°C and a pressure of -0.01~-0.08MPa under stirring, and prepare a spinning solution. Defoaming, dry-wet spinning and post-treatment are used to obtain water-soluble polyvinyl alcohol fibers. The water-soluble temperature of the fibers is 10~90°C, the strength is ≥3.5cN/dtex, the single fiber fineness is 1.5~10dtex, and the elongation at break is 15~30 %, its filaments are processed into wool tops, blended with wool tops, cotton slivers, hemp and chemical fibers to make high-count yarns or hollow yarns, or cut into short fibers for non-woven fabrics, embroidery base fabrics and various purposes in papermaking .
