1. Pay attention to rain protection and do not construct in rainy days.
2. The moisture-proof layer must be added for cold insulation. Under the condition of special low temperature, the resin-free rock wool is used for thermal insulation, and the moisture-proof layer must also be fireproof
3. When the temperature exceeds a certain temperature, such as 200 ℃, the insulation must be provided with appropriate external protection, so as not to change the thickness and bulk weight of the rock wool board.
4. When the finished rock wool insulation for large diameter and flat wall equipment exceeds 200 ℃, it is necessary to remember the advice of the rock wool board manufacturer: add insulation nails (with a spacing of about 400mm), and the outer protection should be tight.
5. For equipment, insulation nails and pipes requiring insulation, proper coating can be accepted to facilitate corrosion protection. In addition, there should be no leakage. This can achieve better results.
6. If the finished rockwool board is subject to mechanical wear under outdoor thermal insulation, it is advisable to use metal or plastic wrapping, and then pay attention to the joint location and joint sealing, and add plastic sealing strip if necessary. The stacking part of the wrapping layer shall not be less than 100mm
7. When the thermal insulation object is placed at 90 degrees and has a certain height, the thermal insulation layer of rock wool board must have positioning pins or support rings, and the spacing must not be greater than 3 meters, to prevent the thermal insulation material from sliding downward in case of vibration.
8. In order to achieve the goal of minimum heat loss, the joints of rock wool board and felt must be tightly butted. If there are multiple layers of insulation, the cross joints need to be interwoven to avoid forming a thermal bridge. The cold bridge must be completely eradicated during cold insulation.
