Excellent thermal insulation material
Core Tip: Several major fire accidents happened in recent years in China are related to thermal insulation materials for building exterior walls, so fire prevention of thermal insulation materials has aroused great concern again. At present, the materials used for building exterior wall insulation are silicate insulation materials, rubber powder polystyrene particles, steel mesh foam board, etc. The performance of fire prevention and environmental protection is not ideal.

Rock wool is a kind of natural environmental friendly fireproof, adiabatic thermal insulation material. It is made of natural rock, blast furnace slag as the main raw material, plus a certain number of auxiliary materials, by high temperature melting injection and artificial fiber, and then used to make rock wool products. The highest temperature of rock wool can reach 650 degrees Celsius. The board, felt, pipe shell and granular cotton made of rock wool can resist high temperature and is suitable for the insulation of industrial high temperature equipment. At present, rock wool is also widely used in building exterior wall insulation, fire prevention and heat insulation. In the late 1970s, foreign countries began to attach importance to the production of rock wool insulation materials and their application in building energy conservation, and strive to significantly reduce energy consumption, thereby reducing environmental pollution and greenhouse effect. Nowadays, the application of rock wool insulation materials on the external walls of foreign buildings has been relatively mature, and the insulation materials for building energy saving account for the vast majority. For example, in the United States, Sweden and Finland and other countries, more than 80% of rock wool is used for building insulation and energy conservation; in Germany, the law clearly stipulates that the use of organic flammable insulation materials (such as polystyrene materials) is strictly prohibited in buildings above 22 meters in height, most of which use rock wool as interior insulation, exterior wall and roof insulation materials.
Recently, the international authority pointed out in the analysis report that China's insulation material market demand will be 9% annual growth rate. At present, rock wool has been widely used in industry and construction industry because of its good insulation, heat insulation, fire prevention, sound absorption characteristics, environmental protection, economic and practical advantages.
Rock wool with its non-flammable, non-toxic, low thermal conductivity, sound absorption performance, insulation, chemical stability, long service life and other characteristics, is recognized as an ideal thermal insulation material at home and abroad, will also be excellent insulation, thermal insulation, fireproof performance occupy the building exterior wall insulation material market.
Rock wool can be used in agriculture as well as in construction and industry. Ultra-low density rock wool board is green and environmental protection, which pioneered the production of green food in the field of soilless cultivation. Ultra-low density rock wool board is the best substrate for soilless cultivation. It can be used to grow fruits, vegetables, flowers and trees, lawns and so on. It is more environmentally friendly.
