In the construction process of rock wool color steel sandwich panels, some problems cannot be ignored. The following problems should be paid attention to

There will be some problems in the construction of rock wool sandwich panels, and specific problems require specific solutions.

1. Ensure that the insulation material does not have any leakage problems, and the surface needs to be dry, free of grease, and no rust before taking appropriate coating. .

2. The rock wool material is used for outdoor heat preservation or places susceptible to mechanical wear. Pay attention to the tightness of the joints. If necessary, add a rubber seal to make it tighter. Then the overlapping part is not less than 100mm.

3. If it is used for cold insulation, a moisture-proof layer must be added. When the outdoor temperature is particularly low, rock wool should be used for thermal insulation, so that the temperature can be slowly warmed up.

In order to avoid the loss of too much heat due to too high, then please pay attention to the place where the board and the felt are connected must be very close to each other, and each connected place needs to be staggered for multi-layer insulation. , so as to avoid the formation of thermal bridges. When the temperature is too high over 200 ℃, a layer of outer protection needs to be added, so that the rock wool board will not be deformed if it expands.
