Polyurethane shell and tube

Products polyurethane foam pipe shell with a high functionality polyether polyol and polymethine polyphenyl polyisocyanate as main raw materials, catalyst, foaming agent, surfactant, etc., under the action of polyurethane foam pipe shell foaming chemical reactions percent. Polyurethane foam shell and tube capacity, light weight, high strength, thermal insulation, sound insulation - flame retardant, cold-resistant, anti-corrosion, non-absorbent, fast and easy construction excellent characteristics such as polyurethane foam shell and tube construction, transport, petroleum, chemical, power, refrigeration indispensable materials and other industrial sector thermal insulation, waterproof plugging and sealing. Bicomponent product properties of polyurethane foam pipe shell with an isocyanate, a polyol (a combination of polyether or polyester) urethane foam pipe shell as a main raw material and adding an additive composition, polyurethane foam, shell and tube construction by spot spraying a waterproof and heat insulating function of the hard use of the foam insulation layer - Polyurethane foam-site pouring cans or preformed Fuyu steel pipe anti-corrosion layer, the method is simple, quick ergonomics. The performance characteristics of the polyurethane foam pipe shell with isocyanate, polyol (a combination of polyether or polyester) urethane foam tube shell as the main raw material of adding an additive composition two-component, polyurethane foam, shell and tube construction by spot spraying a waterproof and heat insulating function of the hard foams. Rigid polyurethane foam, polyurethane foam shell and tube suitable for on-site construction method of spraying non-exposed insulation and waterproof material. Its low thermal conductivity of polyurethane foam shell and tube, only 0.018 to 0.024W / (m? K), equivalent to half of the EPS, polyurethane foam shell all insulation materials, the lowest thermal conductivity and thermal performance, but also has aging resistance, chemical stability, moisture excellent waterproof, temperature does not melt, etc.. Implementation of the polyurethane foam shell and tube Standard: JC / T 998 - 2006, JGJ14 - 1999, GB10800 - 1989. Construction technology of polyurethane insulation pipe its excellent performance, the long and oft Welcome to facilitate the construction and the useful life of the structure of three parts: the outer protective layer, insulation layer, anti-leakage layer, the outer protective layer is made of polyethylene or fiberglass or other materials. Laying buried, aerial, trench three ways. Our factory has accumulated a lot of experience in the long-term tube polyurethane insulation, insulation construction, its quality reaches the national and international standards. Note polyurethane insulation tube fat from slow this phenomenon generally, because the temperature is suddenly reduced or low temperatures due to appear in autumn and winter, or in the morning construction. The ambient temperature, the temperature rise of the black material can be solved. Generally black material temperature rose to 30-60 ℃, 20-30 ℃ ambient temperature rises can be. Polyurethane insulation tube from the hair speed fast this phenomenon usually appears in the spring and summer or noon construction, because the sudden increase in temperature thing too due to temperatures. The black material Ling with cold water or a night on the outdoor natural cooling, avoid direct sunlight. Polyurethane pipe insulation foam strength smaller and softer foam disorders caused by this phenomenon by the proportion of black and white material, and increase the proportion of black material can (1:1-1.05) Note that is not in the proportion of black material too, otherwise, would bubble droplets become brittle, also affect the foam performance. Other explanatory due to the polyurethane foam obturator rate of more than 92% of the polyurethane foam insulation layer as a buried pipe can not only play an insulation effect, and can effectively prevent water, moisture, as well as a variety of other corrosive liquids, gases, soaked to prevent the breeding and development of micro-organisms. Transaction must meet the design requirements consistent with the physical description of the product specifications and product performance!
