Shuangxin Brand PVA 1799 For Textile Sizing
Description:
Features
(1) Solubility: Strong hydrophilicity, easily soluble in water (usually dissolved in hot water above 90 °C), insoluble in almost all organic solvents.
(2) Film-forming: easy to form a film, and its film has excellent mechanical properties. Except for H2O, the PVA film has excellent barrier properties to H₂, N2, O2 and other gases.
(3) Adhesion: It has good adhesion with hydrophilic cellulose, paper, etc.
(4) Thermal stability: When the sheet is heated to above 130 °C, the appearance changes gradually. Complete alcohols of PVA begin to melt at around 230 °C, and begins to decompose above 200 °C.
(5) Solvent resistance: PVA has strong resistance to weak ACID and weak alkali, and has good oil resistance.
(6) Reactivity: It has excellent cross-linking reactivity, can cross-link with boric acid, etc., and undergo acetyl reaction with formaldehyde, acetaldehyde, etc., and the product has water resistance.
Application:
(1) The solution prepared by the product can be used as a thickener and an anti-sag agent for the emulsion.
(2) Sizing for paper surface can improve paper strength and ink absorption.
(3) The cross-linking properties of the product can be used to formulate various water-resistant adhesives.
(4) For the production of papermaking and construction glue.
(5) For the production of Polyvinyl Alcohol fiber and water-soluble fiber.
(6) Slurry for fiber: It has good film forming performance, has the characteristics of soft and strong tensile strength and elasticity, and is also rich in friction resistance, implication, smoothness and feathering effect. And compared with starch slurry, there is no need to worry about spoilage and mildew.
