Description
Technical field
The present invention relates to a class warming plate, especially relate to a class polyurethane steel face heat preserving composite board and manufacture method and application.
Background technique
Ventilation duct is as the important component part of heating ventilation and air-conditioning system in the modern architecture, its material is along with continuous progress in science and technology develops, the kind of air-line system is also constantly upgraded, as: traditional galvanized sheet iron airduct, inorganic glass fibre reinforced plastic blast pipe, combined light thermal insulation wind pipe.Combined light thermal insulation wind pipe core has rock wool, polystyrene foam, phenol formaldehyde foam, polyurethane foam etc.Though advantages such as heat-insulating property is good, appearance looks elegant that compound rock wool, polystyrene foam airduct have, suction easily, exposed glass fibre is harmful, and heat insulation effect is relatively poor relatively, increases building weight.Adopt plan strategies for people's such as scholar T.L.Satty analytic hierarchy process (AHP) of the U.S. composite pnenolic aldehyde foam, polyurethane foam airduct to be carried out the overall merit of overall performance.
Notification number is that the utility model patent of CN200989495 discloses a kind of dual-layer colour steel polyurethane airduct, is formed by connecting by the plurality of sections airduct, and described each section airduct is composited by the polyurethane in outer field color steel, mesosphere and the color steel of internal layer.Wherein, outer field color steel thickness is 0.3～1.0mm, and the polyurethane thickness in mesosphere is 20～30mm, and the color steel thickness of internal layer is 0.3～1.0mm, and three layers add together thickness at least more than 20mm, so the strength ratio of airduct is better.In being used in air-conditioning system because polyurethane material itself has insulation effect, so it does not need to be incubated again by other approach, thereby also saving of labor of material-saving.In addition, because the polyurethane in mesosphere is the high density rigid material, so air leakage phenomena can not occur, tightness is good.
Notification number is that the utility model patent of CN200968452 discloses a kind of color steel polyurethane airduct, is formed by connecting by the plurality of sections airduct, and described each section airduct is composited by the polyurethane in outer field color steel, mesosphere and the aluminium foil of internal layer.Wherein, outer field color steel thickness is 0.3～1.0mm, and the polyurethane thickness in mesosphere is 20～30mm, and the aluminum foil thickness of internal layer is 60～200 μ m, and three layers add together thickness at least more than 20mm, so the strength ratio of airduct is better.In being used in air-conditioning system because polyurethane material itself has insulation effect, so it does not need to be incubated again by other approach, thereby also saving of labor of material-saving.In addition, because the polyurethane in mesosphere is the high density rigid material, so air leakage phenomena can not occur, tightness is good.
