polyurethane exhaust duct, aluminum foil duct polyurethane, polyurethane ventilation pipe, polyurethane composite duct inside adopts special glass fiber cladding, thermal isolation fiber, coating glue; External coating special glass fiber, spiraling clamp type structure, stainless steel ( VA) ; Widely used in all types of plant, the room that defend bath, electronics factory, sewers, shipyard, refrigeration, ventilation environmental protection projects. Drainage of smoke, moisture, dust, high temperature gas, ventilation, etc.
polyurethane exhaust duct, aluminum foil duct polyurethane, polyurethane ventilation pipe, polyurethane composite duct on each attribute index introduced:
1. Strength: the mechanical structure is stable, compressive resistance to deformation.
2。 Small coefficient of thermal conductivity: the architectural institute of 0. 024w( M。 K) , better than other commonly used thermal insulation material.
3。 Fire prevention performance is good: more than the national standard GB8624 - 97 pipe heat insulation foam plastics combustion performance grading method in the BI level requirement. In the polyurethane industry reached leading level at home and abroad.
4。 No pollution: duct inside and outside of the aluminum foil, the surface of AL2O3 has stable chemical properties, does not constitute any pollution to the environment.
5。 Long service life: inside and outside duct for aluminum plate, the surface has the stable AL2O3, middle insulation layer is a polymer material, the service life of the four to six times that of traditional duct.
6。 Light: the weight of 2. 0, is a traditional duct 1/5 ~ 1/6.
7。 Airtight performance: no leakage. Also has been widely used in high pressure air supply system.
polyurethane exhaust duct, aluminum foil duct polyurethane, polyurethane ventilation pipe, polyurethane composite duct with resistance to acid and alkali, chemical waste, flame retardant, wear-resisting, resistance to pull and any expansion of universal shift, and other functions; Is suitable for high temperature hot gas boiler smoke, car exhaust emissions, solder cigarette factory, blast heater eduction and welding gas discharge, used for exhaust equipment, engine structure, heat engines, such as dust, solid powder and fiber, such as steam and smoke gas environment, dust removal and extraction plant, heaters, aircraft equipment and military harmonic bellows and compressor, low pressure environment.
