The height of modern buildings is getting higher and higher, the volume is getting bigger and bigger, and more and more people can be accommodated, and the safety is paid more and more attention. At the same time, my country advocates energy conservation, emission reduction, and low-carbon economy, so building thermal insulation and fire prevention is imminent. When a building catches fire, in addition to some unexpected factors, the flammability of thermal insulation materials is also an important hidden danger, which should not be underestimated. It is extremely important to correctly select fireproof and thermal insulation materials and prevent problems before they occur. Rock wool insulation board not only has outstanding thermal insulation performance, but also has excellent fire performance, reaching the A-level non-combustible standard. It is a thermal insulation and fireproof material that can provide users with safety, comfort and satisfaction.
In order to standardize the use of building insulation materials, my country issued the "Interim Regulations on Fire Protection of External Thermal Insulation Systems and External Wall Decorations for Civil Buildings" as early as 2009, which clearly requires that the combustion performance of external wall thermal insulation materials should be Class A. The high-quality rock wool insulation board is made of inorganic substances such as feldspar, white feldspar and basalt as the main raw materials, and is made of rock wool fibers after being melted at high temperature. This material has good fire resistance, high stability, and thermal conductivity. The coefficient does not change with time, the expansion rate is low, and no additional stress is generated on the surface mesh cloth, mortar, etc. due to thermal expansion and contraction. Rock wool does not contain active elements and corrosive components, nor does it contain solvents, oily substances or softeners that affect the building. It is not easy to age and can have the same life as the main building. As one of the grade A non-combustible materials, rock wool insulation boards are widely promoted in China due to their superior technical performance, while some slag rock wool boards are prohibited from being used in external wall insulation because their performance cannot meet the requirements of external wall insulation materials. field.
Due to the occasional occurrence of building thermal insulation fire incidents in recent years, it has caused everyone to think about how to combine thermal insulation and fire protection performance. Because the rock wool insulation board is very stable, the size will not be stretched, contracted or deformed due to heat and cold, the melting point is higher than 1000 ℃, and no harmful substances and gases will be released in the fire. It is an ideal exterior wall material. It is not a non-carcinogenic substance, and does not contain harmful substances such as CFC, HFC, and HCFC. It will not be corroded, mildewed or breed bacteria, and it can stand the test of time in the field of external wall insulation, so it is widely used and provides a good opportunity for the development of rock wool insulation boards.
