The sealing performance of color steel rock wool sandwich panel is relatively good. This product is generally produced and processed by assembly line. The overall appearance of the product is similar. Polyurethane is used for sealing on both sides. The manufacturer of rock wool sandwich panel can effectively solve the problem that rock wool is easy to absorb water and return to moisture, and improve the service life of the product to a certain extent, Therefore, the performance of polyurethane rock wool sandwich panel will be more stable.
When selecting rock wool sandwich board products, the stiffness of the sandwich board is very important. If it is too soft, it will cause bending deformation of color steel rock wool board, which is easy to lead to collapse and other accidents. The outside of the rock wool sandwich board is wave shaped. The plate made by rock wool sandwich board manufacturers has much higher stiffness and strength than ordinary composite shaped rock wool board, After the rock wool sandwich board and purlin are firmly fixed, the strength of the board surface can be well improved.
The fixation method of color steel rock wool sandwich panel should be reasonable. It is common that both sides of polyurethane rock wool sandwich panel are fixed with purlins and screws. This special purlin and screws can be used to fix the sandwich panel well. Rock wool sandwich panel manufacturers can effectively resist the influence of earthquake and typhoon.
The surface of the purchased rock wool sandwich panel must be protected against scratch, so as to prevent the polyurethane on both sides from being scratched, which will cause rainwater and air to enter the sandwich panel. Over time, it is easy to damage the panel. Therefore, pasting the protective film of polyethylene self-adhesive on the color steel rock wool sandwich panel can prevent the panel from being scratched during transportation and handling.
