What are the selection methods for rock wool sandwich panels?

The sealing effect of the rock wool sandwich panel is good, and the sandwich panels are generally produced in an assembly line, and the appearance of the entire product is almost the same. Both sides of the sandwich panel are sealed with polyurethane. The function of polyurethane is relatively good. Because it absorbs water easily, it can overcome the phenomenon of rock wool regaining moisture and greatly improve the service life of the rock wool sandwich panel. Therefore, when choosing sandwich panels, you must choose a polyurethane rock wool sandwich panel.

The stiffness of the sandwich panel is very important. If it is too flexible, the sandwich panels will simply bend and deform, causing collapse etc. Polyurethane makes the rock wool sandwich layer well sealed, so that polyurethane and rock wool become a whole. Moreover, the outer surface of the sandwich panel forms a wavy compression, which is much higher than that of ordinary composite compression panels with rock wool. When the rock wool sandwich panel is firmly fixed by the strips, the rigidity and strength of the layout can also be better improved.

The fixing method of the rock wool sandwich panel should be firm and reasonable. It is a common practice to choose select strips and screws to fix both sides of polyurethane. This special purlin and screws can fix the sandwich panel very well, and it can resist earthquakes below magnitude 8 and hurricanes below magnitude 10.

The appearance of the rock wool sandwich panel must have anti-scratch protection to prevent the polyurethane on both sides from being scratched. Rainwater and air will enter the sandwich panel, and the sandwich panels will be damaged after a long time. As a result, a polyethylene self-adhesive protective film is pasted, which prevents the sheet from being scratched during shipping and handling.

The rock wool sandwich panel should also pay attention to its appearance. The interface is generally designed and produced according to European standards. The surface of the panel is smooth, the joints are tight, and the strength should be reliable to avoid cracking the panel due to thermal expansion and cold contraction.
