The development and application of cold sandwich structure of polyurethane insulation board technology to promote the development of a combination of cold storage construction techniques, since the sandwich structure system having a light weight, high strength, excellent insulation effect and ease of construction, can greatly shorten the construction period and reduce construction costs Wanning cold plate specifications, so the development direction of cold storage is the use of polyurethane or polystyrene sandwich cold sandwich to build a combination of body structures. Cold sandwich panels used in combination of two types, namely, polyurethane and polystyrene sandwich panels sandwich panels, due to the strength of the polyurethane sandwich panels, insulation and other better than polystyrene sandwich panels, so the polyurethane sandwich panels generally more used in frozen or cold storage temperature lower library, polystyrene sandwich insulation properties due to better and more affordable and generally used in ordinary cold storage high temperature cold storage and food processing plants and other industrial and civil buildings on. See attached Schedule overall performance and two sandwich panels. Since these two sandwich has excellent performance, and therefore can be widely used in various other industrial and civil buildings. Electric refrigerator door installation materials ⑴ seal: Wanning imported EPDM rubber modified cold plate specifications, high resistance, low temperature, aging, acid, good sealing, long life; ⑵ hardware accessories: hard aluminum alloy Rail pressing, other stainless steel accessories, high precision, open and flexible, effort and nice; ⑶ antifreeze device: low around doors fitted with a thermostat antifreeze electric heating means; (applies to the following 5 degrees cold) ⑷ escape device: people strayed into the library, the library door with a danger handle without damaging doors, driving opener can successfully escape. ⑸ air curtain: high pressure centrifugal fan and duct are stainless steel (also with color-coated steel material) Mannings cold plate specifications, reduce the loss of cold; ⑹ insulation materials: doors door body filling rigid polyurethane material, the use of imported high-pressure injection foam molding equipment; ⑺ main frame and the cheese board: high-quality pine wood, the finished products after the completion digester using tung oil, to increase its corrosion performance; ⑻ facade and door sides of bread: using the original stainless steel wire drawing board materials. ⑼ main frame Hemming: stainless steel. ⑽ sub-frame: made of wood, covered with stainless steel. ⑾ door seal: imported plastic processing, good sealing performance and wear resistance; ⑿ electronically controlled electric refrigerator door Cabinet: ABS waterproof Cabinets body.
