Polyurethane foam pipe insulation Hotline: 15731772986 polyurethane foam with a variety of materials strong bond, so as insulation buried pipe is simply no need to ponder the question coating bonded thereto. Habit temperature polyurethane insulation layer is + 120 ℃ -196 ℃, short-term (ten hours) up to + 190 ℃. If users need long-term temperature of 190 degrees, it can feed the molding temperature according to user needs. Insulation widely used in liquid, gas delivery pipeline, chemical pipe insulation works in petroleum, chemical, central heating network, central air conditioning and ventilation pipes, municipal engineering. High temperature prefabricated buried pipe insulation is a good insulation function, plus safe, reliable, low construction cost of prefabricated buried pipe insulation. Effective treatment of rural central heating in 130 ℃ -600 ℃ high temperature heat transport prefabricated buried pipe insulation insulation, sliding smooth and waterproof doubt exposed pipe ends. High temperature prefabricated buried pipe insulation not only has the traditional trench and overhead laying pipeline is difficult to compare the advanced skills, useful features, and also has significant social and economic benefits, but also a powerful way of heating energy. High temperature prefabricated buried pipe insulation chosen buried heating pipe skills, skills development indicates that China's heating pipes now entered a new starting point for the production of polyurethane pipe insulation program:. ① spraying solution according to the formula will leave the reservoir in two groups barrel, the material to filter to the metering pump, the pneumatic motor femoral artery and work, will be expected to enter the feed tube to the gun body, the compressed air regulating valve material into the mixing chamber, the mixing nozzle after the nozzle, spray the pipeline foaming or on device. ② perfusion solution will create good groups respectively stored in the barrel to filter to the metering pump, the pneumatic motor femoral artery and work, the material input to the infusion tube mixer by way of compressed air introduced into the perfusion motor, femoral artery and mixing shaft so that two materials are mixed, and then write the mold foam molding. Fourth, the polyurethane foam-Construction Notes: mixing materials at room temperature, to mix response, then demand a faster infusion molding space, the construction should control the foaming reaction time, the mixture was after mixing liquid was poured into a clearing in. In the foaming process, it will be a large swelling occurs vigorously respond perfusion model sandwich or do proper reinforcement. The above points are our polyurethane foam for use of the skills of some of the approaches and considerations.
