Detailed Description

The "V Brand" Polyvinyl Alcohol is made from vinyl acetate produced by means of the calcium carbide route, with methanol as its solvent and azo-diisobutyronitrile as the initiator, through polymerization, alcoholysis, disintegration, separation and desiccation. This company has now had two sets of PVA production devices, one produces flocculent PVA of high alkali alcoholysis, the other does flaky PVA of low alkali alcoholysis. The major specifications of "V Brand" Polyvinyl Alcohol (PVA) of our company are the following series of 17-99F(L), 17-99F(H), 17-99 (L), 17-99(H), 18-99(L), 18-99(H), 19-99(L), 22-99(L), 19-88, and the like. Special PVA of different viscosity and alcoholysis can be produced according to the requirements of our customers. Besides, PVA powder with mesh numbers 20-60 can also be provided. The PVA production facilities of our company have been perfecting day by bay with the long-term absorption and technological transformation on the basis of importing the complete set of technology from Kuraray Company of Japan. PVA produced by our company is good in performances and stable in quality. It enjoys a great reputation both at home and abroad. Flocculent PVA has the characteristics of white appearance, soft and bulky feel, even and moderate fibrousness; good water solubility and stable inner quality, etc. It has been honored "Excellent Quality Product" and "Famous Brand Product" by the Ministry of China Chemical Industry and Hunan Provincial Government successively. Flaky PVA has the characteristics of white appearance, soft and bulky feel, even and moderate fibrousness; good water solubility and stable inner quality, etc. It has been honored "Excellent Quality Product" and "Famous Brand Product" by the Ministry of China Chemical Industry and Hunan Provincial Government successively. Flaky PVA is characterized by its white appearance, shaping in tiny particles, high purity and quick dissolution (about one third of the time can be shortened/saved when it dissolves, comparing with the likes in the same lines of our country). Of the series, PVA 19-99(L), which is a product of high viscosity, is especially applied to making coatings and adhesive. Its viscosity is (35.0-45.0) mpa.s, and its glue output rate is (5-10)% higher than the likes of the same internal lines. The Quality Inspection Department of our company has been evaluated "Top Grade Quality Inspection Organization" by the Ministry of China Chemical Industry. The quality certification system for this product was authenticated in line with GB/T 19002-1994-ISO9002: 1994 with the registration number 0601B00298RIL. Application: PVA 17-99(L) is chiefly used to produce textile sizing materials, coatings, adhesive and it is widely used for paper processing, emulsifying agents, dispersants and blocking colloids. Besides, it can be employed as membranes, soil modifiers, etc. PVA 19-99(L) and 18-99(H) are particularly applied to making coatings and adhesive. PVA 17-88 is chiefly used for coatings, adhesive, dispersing agents, emulgents, textile sizing materials, sensitize coatings and so forth. Attention: The contents of NaAC in flaky PVA is lower the PVA in the form of floss, and its PH value is different due to the differences of the technological processes. Processes. Proper adjustment ought to be done according to the requirements for PH value. In the quality system. Explanation of the standard code: H: High Alkali Alcoholysis L: Low Alkali Alcoholysis F: Mainly used as a raw material of the production of Vinylon fiber Without F: Other uses except for Vinylon fiber 99: Alcoholysis 17: Polymerization
