Water-sealed gate valve is suitable for thermal condensing system of thermal power station with working pressure of 1.6 ~ 10.0MPa and working temperature of 0 ~ 425 ℃, and the pipeline which is isolated from the atmosphere for petroleum and chemical industry. Products, steam, and non-corrosive gases.
Polyurethane foaming equipment can be used for automotive interior decoration, insulation wall spraying, insulation pipe manufacturing, and bicycle and motorcycle seat sponge processing. Polyurethane foaming equipment has excellent thermal insulation performance, even better than polystyrene board, and has become the best thermal insulation material in construction equipment. In addition, the waterproof performance of the polyurethane foaming equipment is also certain, because its foam cells are kept closed, and the sealing rate is very high, and rainwater will not penetrate through the cells. Generally, the polyurethane foam equipment is sprayed on-site, so it will form an integrated waterproof layer, no seams will be created, and it will not take much time to repair. Polyurethane foaming equipment has very good bonding performance. It can be firmly bonded to materials such as wood or metal, and it will not be exposed in windy environments. So how efficient is its construction?
