Thermal insulation cotton is a non-toxic, harmless and non-polluting new thermal insulation material made of high-purity clay clinker, alumina powder, silica powder, chromite sand and other raw materials.
Thermal insulation cotton can be further processed into fiber blanket, board, paper, cloth, rope and other products. Ceramic fiber is a high-efficiency thermal insulation material, which has the characteristics of light weight, oxidation resistance, low thermal conductivity, good flexibility, corrosion resistance, low heat capacity and sound insulation.
Insulation cotton is made by melting high-purity clay clinker, alumina powder, silica powder, chromite sand and other raw materials in an industrial electric furnace at high temperature to form a fluid. Then use compressed air injection or spin spinning machine to spin the silk into a fiber shape, and collect the cotton through a cotton collector to form thermal insulation cotton. Thermal insulation cotton can be further processed into fiber blanket, board, paper, cloth, rope and other products. Ceramic fiber is a high-efficiency thermal insulation material, which has the characteristics of light weight, high strength, oxidation resistance, low thermal conductivity, good flexibility, corrosion resistance, small heat capacity and sound insulation.
Thermal insulation cotton can be used alone as a thermal insulation and cold-proof material and widely used in passenger trains, stadiums, and theaters. It is an ideal substitute for glass wool as a cold-proof material. It is in direct contact with human skin and will not produce any harmful effects. It is a new type of non-toxic, harmless and pollution-free thermal insulation material.
1. Introduction to the types of air-conditioning insulation cotton
Air-conditioning insulation cotton is generally foamed with materials such as polystyrene and polyurethane. The air conditioner needs insulation cotton. The air conditioner is protected by the air conditioner insulation cotton, which promotes the better operation of the air conditioner, thereby ensuring the effect of the air conditioner. The so-called air-conditioning insulation cotton refers to a material for insulating air-conditioning. Air-conditioning insulation cotton is non-toxic, harmless and non-toxic, made of high-purity clay clinker, alumina powder, silica powder, chromite sand and other raw materials. Contaminated new thermal insulation materials.
2. Air-conditioning insulation cotton type-rock wool
(1) Rock wool pipe is a new type of heat preservation, heat insulation and sound absorption material.
(2) The rock wool piping system is made of selected basalt as the main raw material and melted into artificial inorganic fiber at high temperature. It has the advantages of light weight, low thermal conductivity, good sound absorption, non-combustibility, and good chemical stability.
(3) Rock wool pipe also has the properties of waterproof, heat preservation, heat insulation and cold insulation, and has certain chemical stability. Even if it is used for a long time under humid conditions, it will not deliquesce. Because its products do not contain fluorine (F-) and chlorine (CL), rock wool has no corrosive effect on the equipment and is a non-combustible material.
3. Types of air-conditioning thermal insulation cotton—rubber and plastic thermal insulation cotton
Rubber-plastic insulation material is an elastic closed-cell elastic material, which has excellent properties such as softness, bending resistance, cold resistance, heat resistance, flame retardant, waterproof, low thermal conductivity, shock absorption, and sound absorption. It can be widely used in central air conditioning, construction, and chemical engineering. , Textile, metallurgy, communication, vehicles, electrical appliances and other industries and some of the various cold and heat medium pipes and containers can achieve the effect of reducing cold and heat loss. In addition, the construction is simple, the appearance is neat and beautiful, and the product does not contain fiber dust, and will not breed any harmful substances such as mold, so it is a high-quality new generation of thermal insulation material that crosses the century.
