COLD ROOM PANEL CONTINUOUS PU LINE
The PU sandwich panel continuous production line is best for buidling material with best flame resistance, heat/cold preservation, insulation, sound insulation, waterproof, light weight, environmental protection and other functions. It can be widely used in cold rooms, prefab buidling, factory buildings and more.
The production line mainly produce three types of panels:
1. Metal hard surface layer hidden wall panels ( can produce PUR/PIR board, rock wool board, PU edge sealed rock wool board on both sides).
The surface material is formed by steel plate, the effective width of the plate is 1000mm, the unfolded width of the upper and lower steel plates is 1070/1200mm. Wall panel with a width of 1000mm has small corrugation of 20mm width or square wave small ribs with a spacing of 100mm. The width of the wall panel is 1000mm on the bottom plate. There are square wave small ribs with a spacing of about 100mm and small corrugations with a width of 20mm. The lap method is seamless hidden or wide seam (20mm/40mm) hidden. For details of the plate type, please refer to the plate type diagram.
The20mm wide seam hidden wall panel can produce PU board, rock wool board, PU edge sealed rock wool board on both sides. Wide seam 40mm hidden wall panel can produce PU board, PU edge sealed rock wool board on both sides but no full rock cotton board.
2. Metal hard surface cold storage board (PU/PIR board can be produced with a thickness of 50 -100 can be used as partition board. The Surface material is formed color steel plate and stainless steel plate. The effective wid0th of the plate is 1000mm, the unfolded width of the upper and lower steel plate is 1080/1080mm, and the width of the composite plate is 1000mm. The 1000mm wide composite board panel is a rectangular square wave with a spacing of 100mm and a small corrugation with a width of 20mm. The lap method is an open type. The board type is shown in the board type diagram. Note: The board width of cold storage mainly meets the board width of 1120mm for production.
The production and formation process of the composite board is formed by continuous spray foaming of polyurethane in the middle of the formed surface material, and the crawler moves forward at a uniform speed, where the polymerization reaction occurs and the composite solidifies together. After the composite board is fully formed, the cutting is cut according to clients desired length and the production line does not stop during cutting process.
