Polyurethane edge sealing rock wool sandwich board is a kind of artificial inorganic fiber, slag, dust content and non water absorption board made of natural rocks of good quality such as basalt and gabbro, which are mainly raw materials of the original Chaozhou rock wool sandwich board manufacturer. It is made of high-temperature melting and fibrosis. In particular, its waterproof property is prominent, which is shown in the following points.
1. The polyurethane edge sealing rock wool sandwich panel uses light polyurethane as the psychological data of the cold storage panel. The advantage of polyurethane is that the waterproof and heat insulation functions are very good. The exterior of the polyurethane edge sealing rock wool sandwich panel is made of color steel plate and stainless steel plate components. The advantage of this is to avoid the temperature transmission of the cold storage panel due to the large internal and external temperature difference, so as to make the cold storage more energy-saving and improve the working efficiency of the cold storage.
2. Polyurethane edge sealing rock wool sandwich panel is fireproof, flame retardant, and resistant to high temperature of Chaozhou rock wool sandwich panel manufacturer. After adding flame retardant, polyurethane is a kind of flame-retardant self extinguishing material. Its softening point can reach more than 120 ° C, and it will decompose only at a higher temperature. In addition, polyurethane will form ash on the surface of its foam when it is burned, which helps to block the underlying foam. It can effectively avoid fire spreading. Moreover, the polyurethane does not generate harmful gases at high temperatures.
3. Due to the excellent waterproof and thermal insulation function of polyurethane plate, the thickness of the outer envelope of the building can be reduced and the indoor use area can be increased under the same thermal insulation requirements.
