Rock wool is an inorganic thermal insulation material, and its fire performance reaches Class A fire protection standards. In order to protect people’s health and property safety, the state stipulates that the external wall insulation materials of civil buildings must reach A-level, and the rock wool board has excellent thermal insulation and sound absorption properties. Therefore, rock wool insulation boards are widely used, widely used in building walls, roof insulation and sound insulation, etc. Rock wool boards are not only widely used in buildings, but also widely used in petrochemical, textile metallurgy, electric power transportation that require thermal insulation and fire prevention , ships and all other places that are prone to fire. Rock wool insulation board has so many advantages and applications, but there are some precautions in construction according to the characteristics of rock wool board. So what are the precautions for rock wool board construction?
Because the rock wool board will deform and expand after absorbing too much water, it is necessary to do a good job of waterproofing the rock wool board, and pay attention to rain protection during construction, and cannot be constructed in rainy days. The rock wool board used for cold insulation must be equipped with a moisture-proof layer. Under the condition of particularly low temperature, the moisture-proof layer should also be fireproof. The finished rock wool board is more susceptible to mechanical wear under outdoor thermal insulation conditions, and should be covered with metal or plastic protection; then pay attention to the joints, seal the joints, and seal with glue if necessary, and the stacking of the cladding layer is not less than 100mm. When the thermal insulation object is placed at 90 degrees, and when it has a certain height, the thermal insulation layer of the rock wool board must have positioning pins or support rings, and the distance should not be greater than 3 meters to prevent the thermal insulation material from slipping off when there is vibration. For the purpose of reducing heat transfer, the seams of the rock wool board must be tightly connected and protected. When used for thermal insulation of chemical equipment pipelines, when the temperature exceeds a certain temperature, such as greater than 200 ℃, the thermal insulation must be protected by a suitable outer layer, so as to avoid the change of the thickness and bulk density of the rock wool board, and some large-diameter, When the rock wool insulation board is used for insulation of flat-wall equipment, insulation nails can be added according to the actual situation, and the outer protective layer should be tightly pasted; and the equipment, insulation nails, pipes, etc. that need insulation can be coated with appropriate coatings to prevent corrosion. , It should be ensured that there is no leakage of equipment pipes, etc., so as to achieve better thermal insulation effect.
Rock wool board not only has a good thermal insulation effect, but also has a high density and can also play a certain role in sound insulation and sound absorption. Jishang new building materials can also customize thermal insulation materials, and can customize the density, thickness, model and size of the production products according to your specific requirements, which can reduce your use process and save costs.
