Rock wool board considerations

2019-06-11

1. Pay attention to rain prevention and not work on rainy days.

2. For the cold preservation, it is necessary to add a moisture-proof layer. Under the condition of extremely low temperature, the resin should be insulated with rock wool without resin, and the moisture-proof layer must also be fireproof.

3. When the temperature exceeds a certain temperature, for example: 200 °C, the insulation must be added with appropriate external protection, so that the thickness and bulk density of the rock wool board will not be changed.

4. For the large-diameter and flat-wall equipment used for rock wool finished products insulation, when surpassing 200 °C, be sure to remember the rock wool board manufacturer's 叮嘱: add insulation nails, (around 400mm spacing) external protection should be close.

5. Equipment, insulation nails and pipes to be insulated are suitable for corrosion protection and can receive appropriate coatings. In addition, there should be no leaks. This can achieve better results.

6. If the rock wool board finished product is subject to mechanical wear in the case of outdoor heat insulation, it should be metal or plastic foreskin. Then pay attention to the joints, seal the joints, add glue seal when needed, and the stack of the wrap layer is not less than 100mm.

7. When the object to be insulated is placed at 90 degrees and has a certain height, the insulation layer of the rock wool board must have a positioning pin or a support ring, and the spacing must not exceed 3 meters to prevent the insulation material from sliding downward when there is vibration. .

8. In order to achieve the minimum target of heat loss, the joints of rock wool board and felt must be butt jointed. If there are multiple layers of insulation, the cross joints need to be interwoven to avoid the formation of a thermal bridge.
