The rock wool composite board is made of natural ores such as basalt as the main raw material. The price of rock wool board is not high. The rock wool insulation board is melted into fibers at high temperature, an appropriate amount of adhesive is added, and then cured and processed. made up of time. The thermal insulation performance of rock wool insulation board has been very good, especially at room temperature, its thermal insulation performance is much better than other insulation boards. In addition, the sound insulation effect of rock wool is also quite good. However, when constructing rock wool insulation board, please pay attention to the following points:
1. Rock wool composite panels are used for refrigeration. Cold surfaces must be covered with a moisture-proof cloth. At low temperatures, it is an insulating resin without rock wool, and its moisture-resistant lining must also be fire-resistant.
2. In order to make the heat loss small, the rock wool composite board must be tightly connected with all the joints. When multiple layers of insulation are used, cross joints should be staggered to avoid thermal bridges.
3. Rock wool composite board products are used for outdoor thermal insulation or metal or plastic wraps that are prone to mechanical wear, and pay attention to joints, joints and seals. If necessary, add rubber seals, and the coating overlap is not less than 100 mm
4. Rock wool composite board insulation, no leakage of pipes. The surface is dry, free from grease and rust. If orange mandarin is used, an appropriate coating may be used to enhance corrosion protection.
5. When the insulation is placed vertically to a certain height, the insulation layer should be provided with positioning pins or support rings, and the distance should not exceed 3 meters to prevent the insulation material from sliding down with the insulation layer. vibration.
6. For the thermal insulation of large-diameter rock wool board products or flat wall equipment, when the temperature exceeds 200 ℃, thermal insulation nails should be added, and the external protection should be tight.
7. When the temperature of the rock wool composite board exceeds 200 ℃, the thermal insulation material should be properly protected so as not to change the thickness and bulk density due to expansion.
8. In rainy days, outdoor thermal insulation and refrigeration construction should not be carried out, otherwise rainproof measures should be taken.
