四川维尼纶厂日前顺利生产出100 t聚乙烯醇(PVA)099-92新产品,其产品最高黏度达到100 mPa·s,填补了国内空白,开创了超高黏度PVA生产先河。新品黏度高出以往产品平均黏度15%以上,产品平均聚合度和黏度均创下国内最高纪录,达到世界领先水平。川维厂通过大量市场调研了解到,高黏度PVA产品在黏合剂、建筑材料等生产领域应用广泛,成为PVA高端产品研发的主攻方向之一。而保证超高聚合度、超高黏度的聚醋酸乙烯原料顺利生产和输送,以及醇解工序设备的稳定长时间运行则成为新品生产需
Sichuan Vinylon Plant recently successfully produced 100 t of PVA 099-92 new products, the highest viscosity of its products to 100 mPa · s, to fill the gaps in the domestic, creating a precedent for the production of ultra-high viscosity PVA. The viscosity of the new product is 15% higher than the average viscosity of the previous product. The average polymerization degree and viscosity of the product all hit the highest domestic record and reached the world advanced level. Chuanwei plant through a large number of market research has learned that high viscosity PVA products in the adhesives, building materials and other widely used in the field of production, PVA high-end product research and development as one of the main directions. And to ensure ultra-high degree of polymerization, ultra-high viscosity of the raw materials of polyvinyl acetate production and smooth delivery, as well as alcoholysis process equipment stable long-term operation has become a new production needs
