PU sandwich panel, PU sheet, strength cold storage insulation board of rigid polyurethane sandwich panels, insulation superior performance, more usually applied on frozen or cold storage temperature lower library, polystyrene sandwich insulation better performance and affordable, more usually used in ordinary cold storage, cold storage and food processing plants on high temperature industrial and civil construction. 1, the library board fixed width 960mm, white color steel panel material, 304 # stainless steel, crimped aluminum. 2, the conventional library board panel: A, choose galvanized steel for painted steel substrate, rather than cold-rolled steel (commonly known as Blackboard) as substrates. Cold plate having a uniform coating, good corrosion resistance, meet the health requirements and so on. B, the Executive GB library board color is white. C, were deposited film library board surface and play a protective role. 3, the library board insulation materials: rigid polyurethane (PU) high-pressure foaming and lamination process, the implementation of standards "JB / T6527-2006", feed density of 40 to 45 kg / m3, thermal conductivity 0.024W / mK, thermal insulation properties much better than polystyrene sandwich board. 4, the library board connections used in all mosaic eccentric steel hooks bump for coupling to ensure that the cold storage library board joints tight and fitted vent cap. Completely overcome the ills brought by other connection means "cold bridges" and to further improve its cold storage library board insulation properties. 5, the company eccentric steel hooks a "hook" There are obvious advantages: A. ensure that the connection between the cold storage library board more closely, slab to a minimum level. B. minimizing the installation cycle, really easy accessibility, it is truly dedicated assembled cold storage cold plate. C. saving installation materials, reduce the use of the installation process negative angle and rivets and other accessories.
