[Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - ventilation ducts ventilation ducts] Material: General: steel duct (ordinary steel), galvanized sheet (galvanized iron) wind pipe, stainless steel vent pipe, FRP ventilation pipe, plastic vent pipes, composite ventilation pipe, color steel sandwich insulation panels ventilation tube, double-sided aluminum foil insulation ventilation pipe, single color steel duct insulation, adhesive cloth ventilation tubes (such as mine ventilation duct), mining plastic ventilation tubes. [Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product -] of the most commonly used types of duct into galvanized sheet steel duct, inorganic fiberglass duct composite fiberglass duct board. Three basic characteristics of galvanized sheet metal duct Duct: One of the earliest use of the duct, made of galvanized sheet steel production, for small amounts of moisture transport general gas pipelines have rust, no insulation and muffler exhaust pipe function, fabrication and installation of the long-cycle characteristics. Inorganic fiberglass duct: newer duct type, the use of glass fiber reinforced inorganic materials, fire burn, corrosion-resistant, heavy weight, hardness but more brittle air defense pipeline, by the weight of the impact deformation crisp crack, no insulation and consumption sound performance, fabrication and installation of a long cycle. Composite fiberglass duct board: The latest type of duct recent years, with the centrifugal glass plate as the substrate ventilation ducts, complex glass cloth, aluminum foil moisture outside the complex fabric (imported sheet is coated with a thermal black acrylic polymer within the outer To dilute Cloth / aluminum foil / kraft paper), after the fire with a special adhesive compound dry, and then by cutting, slotting, bonded reinforcement process and made using special sealants, pressure sensitive tape, thermal tape sealing connection According duct section size, air pressure and then using the appropriate size of the reinforcement measures. With a silencer, insulation, fire, moisture, air leakage is small, light weight, easy construction, saving installation space, long life, economical advantages.
