Detailed introduction to standard size products of polyurethane sandwich panels
Introduction to Polyurethane Sandwich Panel
The width of the warehouse plate is 960/1160mm, and the plate materials include color steel plate, 304 stainless steel plate, embossed aluminum plate
【Conventional Panel】
A. The color-coated steel plate with galvanized steel plate as the base plate is used instead of cold-rolled steel plate (commonly known as blackboard) as the base plate. The cold storage board has the characteristics of uniform coating, good corrosion resistance, and meets the hygiene requirements.
B. The color of the storage board is white-gray according to the national standard.
C. The surface of the storage board is coated with a film to protect the board surface.
【Insulation Material】
The process of hard polyurethane board (PU) is high-pressure foaming and one-time molding. The standard “JB/T6527-2006” is implemented. The feed density is 32-50k/m’ and the thermal conductivity is 0.024W/mK. The thermal insulation performance is significantly better than that of polystyrene sandwich board and extruded board.
【Connection method】
The connection method of the storage board is all connected by inlaid eccentric steel hooks, which ensures the tight joints of the cold storage board and is equipped with hole caps. It completely overcomes the disadvantages of “cold bridge” and cracks caused by thermal expansion and contraction caused by other connection methods, and further improves the thermal insulation performance of the cold storage board itself.
