我国中小型玻璃钢冷却塔自1973年开始试制以来至今已有十年以上的历史。目前冷却塔的生产和使用已很普遍。但在冷却塔的安装和运行中常出现一些弊病和事故,其主要表现在以下几个方面:一、冷却塔的塔体采用聚酯玻璃钢,表面为胶衣树脂层,基层为不饱和聚酯树脂及0.4毫米厚的无碱或中碱无捻方格玻璃布,手工糊制,常温固化。我国手糊成型工艺比较
China’s small and medium sized glass fiber reinforced plastic cooling towers have been more than a decade old since they began trial production in 1973. At present, the production and use of cooling towers are common. However, some drawbacks and accidents often occur in the installation and operation of cooling towers. The main performances are as follows: 1. The tower body of the cooling tower is made of polyester fiberglass, the surface is gel coat resin layer, and the base layer is unsaturated polyester resin. And 0.4 mm thick non-alkali or alkali non-tank square glass cloth, hand-made paste, room temperature curing. Comparison of hand lay-up process in China
