As an important building insulation material, rock wool composite insulation board has been widely used in the construction industry. In order to ensure its performance and quality, certain technical requirements need to be met. This article will introduce and elaborate in detail the technical requirements of rock wool composite insulation board.
First, the appearance quality.
The appearance quality of rock wool composite insulation board is one of the important factors affecting its appearance and use effect. The appearance quality requires that the surface of the plate is smooth, without cracks, dents, impurities and other defects. At the same time, the dimensional deviation of the plate is required to be within the allowable range to ensure the accuracy and aesthetics of installation.
2. Physical properties.
1.Thermal insulation performance.
The main function of rock wool composite insulation board is heat preservation, so its heat preservation performance is one of the important technical requirements. The thermal conductivity of the plate is required to be low, which can effectively prevent the transfer of heat and keep the indoor temperature stable. At the same time, the thermal insulation performance of the board is required to be stable, and there will be no large fluctuations due to changes in ambient temperature.
2.Compressive strength.
Rock wool composite insulation board needs to withstand a certain pressure and weight, so its compressive strength is one of the important technical requirements. The plate is required to have a certain compressive strength, be able to withstand its own weight and external pressure, and ensure that it is not easy to deform and be damaged during use.
3.Fire performance.
Rock wool composite insulation board needs to have certain fire performance to ensure the safety of the building. The fire rating of the board is required to meet the requirements of relevant national standards, have good flame retardant performance, and can effectively delay the spread of fire.
4.Water absorption.
The water absorption rate of rock wool composite insulation board is also one of the important technical requirements. The water absorption of the plate is required to be low, and it is not easy to be damp, deformed or rotten, so as to ensure its long-term use effect and service life.
3. Chemical properties.
1.Weathering performance.
Rock wool composite insulation board needs to be exposed to the natural environment for a long time, so its weather resistance is one of the important technical requirements. It is required that the board can withstand the test of natural factors such as sun and rain, alternating between cold and heat, and is not easy to age, change color or lose its original performance.
2.Corrosion resistance.
Rock wool composite insulation board may be eroded by various corrosive substances during use, so its corrosion resistance is one of the important technical requirements. The plate is required to have a certain corrosion resistance, be able to resist the erosion of acids, alkalis, salts and other substances, and ensure long-term use effect.
Fourth, environmental performance.
1.Inorganic and environmentally friendly materials.
The main raw material of rock wool composite insulation board is inorganic and environmentally friendly materials, which do not contain harmful substances and volatile organic compounds and other harmful components, and is a green and environmentally friendly building material. At the same time, the material can be reused to reduce pollution to the environment.
2.Low-emission production process.
A low-emission production process should be adopted in the manufacturing process of rock wool composite insulation board to reduce environmental pollution and energy consumption. At the same time, the waste generated in the production process should be properly disposed of and reused to reduce the impact on the environment.
