Polyurethane cold storage panel produced by polyurethane sandwich panel manufacturer shall be installed in strict accordance with the installation specification and layout drawing. During installation, the polyurethane cold storage panel shall be properly
cut at the processing site, the board surface film about 5cm on both sides of concave convex groove of cold storage panel shall be torn off, and the inner side of groove shall be treated with continuous sealant.
The polyurethane cold storage board is hoisted to the designated position and fixed with nylon bolts and steel purlin around the wall. When fixing the wall panel, the wall panel is installed from one corner of the outer wall, and the wall panel is installed to both sides based on the skirting board. Each cold storage board is fixed with 6 nylon bolts. When inserting the next board, it is squeezed tightly with the first board, and the convex groove is tight. The plate joint should be controlled at 5mm ± 1mm, which is used for the expansion of polyurethane cold storage plate at low temperature.
When the first polyurethane cold storage board is fixed in place, a continuous guide line will be drawn vertically. This line and the first cold storage board will become the guide line to facilitate the rapid installation and correction of polyurethane cold storage board. Then, the length of the fixed cold storage board shall be measured in certain sections during the installation of each wall area. The length of the fixed cold storage board shall be measured once at the top and bottom to ensure that there is no displacement Moving and fanning. After the installation of one side of the wall panel, tear the film and glue the intersecting parts of the polyurethane cold storage plate. The tear film should be clean without residual points. The glue should be uniform and smooth, and the surface should be concave and curved.
At present, the wall insulation materials widely used in our country are very easy to burn. How to integrate the high-efficiency energy saving and excellent fire prevention of the insulation materials has become an industry problem. Polyurethane exterior wall thermal insulation and fire prevention system, with outstanding fire performance, up to the national class a standard, fire resistance and heat resistance, no melting under high temperature, no dripping, low smoke, good dimensional stability, and has good thermal insulation and energy saving effect, excellent fire performance and good energy saving effect in one, suitable for many fields such as exterior wall thermal insulation. According to the authoritative test of the national quality supervision and Inspection Center for fire protection building materials, the fire protection grade of polyurethane (PIR) board reaches B1, and the polyurethane exterior wall thermal insulation and fire protection system reaches grade A of the national fire protection standard. Under high temperature, it does not melt, soften, diffuse and flame penetrate, so as to fundamentally solve the external thermal insulation fire
