Excellent performance insulation material rock wool attracts attention

Key point: Several major fire accidents that have occurred nationwide in recent years are related to building exterior wall insulation materials, so the fire prevention issues of insulation materials have once again attracted high attention from people. At present, the materials used for building external wall thermal insulation include silicate thermal insulation materials, rubber powder polyphenyl particles, steel mesh foam board, etc., and the fire prevention and environmental protection performance is not ideal.

Rock wool is a natural and environmentally friendly fireproof and thermal insulation material. It uses natural rocks and blast furnace slag as the main raw materials, along with a certain amount of auxiliary materials, to produce artificial fibers through high-temperature melting and blowing, and then uses them to make rock wool products. The maximum operating temperature of rock wool can reach 650 ℃. The boards, felts, pipe shells, granular cotton, etc. made from it can withstand high temperatures and are suitable for insulation of industrial high-temperature equipment. Currently, rock wool is also widely used for external wall insulation, fire prevention, and thermal insulation of buildings. In the late 1970s, foreign countries began to pay attention to the production of rock wool insulation materials and their application in building energy conservation, striving to significantly reduce energy consumption, thereby reducing environmental pollution and greenhouse effect. Nowadays, the application of rock wool insulation materials on the exterior walls of foreign buildings is relatively mature, and energy-saving insulation materials for buildings account for the vast majority. For example, in countries such as the United States, Sweden, and Finland, over 80% of rock wool is used for building insulation and energy conservation; In Germany, it is explicitly stipulated by law that buildings with a height exceeding 22 meters are strictly prohibited from using organic combustible insulation materials (such as polystyrene materials). Most buildings use rock wool as insulation materials for interior walls, exterior walls, and roofs.

Recently, international authoritative institutions have pointed out in their analysis reports that the demand for insulation materials in the Chinese market will develop at an annual growth rate of 9%. At present, rock wool has been widely used in industry and construction due to its excellent insulation, heat insulation, fire resistance, sound absorption characteristics, as well as its advantages in environmental protection, economy, and practicality.

Rock wool is widely recognized as an ideal insulation material both domestically and internationally due to its non flammability, non toxicity, low thermal conductivity, good sound absorption performance, good insulation and chemical stability, and long service life. It will also occupy the market for building exterior wall insulation materials with excellent insulation, thermal insulation, and fire resistance properties.

Rock wool can be used not only in construction and industry, but also in agricultural production. Ultra low density rock wool board is environmentally friendly and has pioneered the production of green food using rock wool as a soilless cultivation substrate in China. Ultra low density rock wool board is the best substrate for soilless cultivation, which can be used to grow fruits, vegetables, flowers, lawns, etc. It is environmentally friendly and pollution-free.
