As a kind of thermal insulation material, with its excellent thermal insulation/cold performance, it is widely used in cooling/heating systems. In addition, rubber and plastic thermal insulation materials can also prevent condensation, which is very useful in the field of central air conditioning. Wide range: Mainly used for air-conditioning system duct and pipeline insulation. Indoor air-conditioning pipelines need to be insulated throughout the entire process. Pipe fittings, valves and metal fittings in contact with the pipeline should be wrapped with insulation materials, especially the joints of insulation materials. Weak links such as pipeline fixed points and valves.
Rubber and plastic insulation materials are used in the insulation applications of construction, industry, pipelines and equipment, and are suitable for cold insulation purposes in various refrigeration projects. Including the energy and chemical industry, textile industry, metallurgy, electrical appliances and other industries in various cold and heat medium pipelines and containers, as well as ships, automobiles and other rail transit fields, the application of rubber-plastic plates or rubber-plastic pipes to reduce cold The purpose of damage and heat damage.
Rubber and plastic can not only come in handy in the insulation of industrial pipelines and equipment, but also rubber and plastic can also have the effect of sound absorption and noise reduction! Rubber and plastic can be used for sound insulation of building wall panels, sound absorption of air ducts and sound absorption decoration of entertainment venues. It is also widely used in the field of noise reduction; it can also be used for impact resistance and decompression of instruments and equipment.
Core reminder: In recent years, several major fire accidents across the country are all related to building exterior wall thermal insulation materials. Therefore, the fire prevention of thermal insulation materials has once again attracted people's attention. At present, the materials used in building exterior wall insulation include silicate insulation materials, rubber powder polystyrene particles, steel mesh foam boards, etc. The fire protection and environmental protection performance is not ideal.

Rock wool is a natural environment-friendly fireproof, heat-insulating insulation material. It uses natural rock and blast furnace slag as the main raw materials, plus a certain amount of auxiliary materials, through high temperature melting and spraying to make artificial fibers, and then use them to make rock wool products. The maximum operating temperature of rock wool can reach 650℃. Boards, felts, tube shells, granular cotton, etc. made of rock wool can withstand high temperatures and are suitable for thermal insulation of industrial high-temperature equipment. At present, exterior wall insulation, fire protection and heat insulation of buildings Rock wool is also used extensively.
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, and strive to greatly reduce energy consumption, thereby reducing environmental pollution and the greenhouse effect. At present, the application of rock wool thermal insulation materials on the external walls of foreign buildings is relatively mature, and thermal insulation materials for building energy conservation account for the vast majority. For example, more than 80% of rock wool in the United States, Sweden, Finland and other countries is used for building thermal insulation and energy saving; in Germany, the law clearly stipulates that the use of organic combustible thermal insulation materials (such as polystyrene materials, etc.) is strictly prohibited in buildings above 22 meters in height. ), most of the use of rock wool as insulation and sound insulation of internal walls, external walls and roof insulation materials.
Recently, an international authoritative organization pointed out in an analysis report that the demand for insulation materials in China will grow at an annual growth rate of 9%. At present, rock wool has been widely used in industry and construction because of its good heat preservation, heat insulation, fire prevention, sound absorption characteristics, and environmental protection, economy, and practical advantages.
Rock wool is recognized as an ideal thermal insulation material at home and abroad for its non-flammable, non-toxic, low thermal conductivity, good sound absorption performance, good insulation, good chemical stability, and long service life. Heat insulation, heat preservation, and fire protection properties occupy the market of building exterior wall insulation materials.
Rock wool can be used in agricultural production besides construction and industrial applications. The ultra-low-density rock wool board is green and environmentally friendly, creating a precedent for the production of green food in the field of rock wool as a soilless culture substrate in China. Ultra-low-density rock wool board is the best substrate for soilless cultivation. It can be used to grow fruits, vegetables, flowers, trees, lawns, etc. It is more environmentally friendly and pollution-free.
