In recent years, with the continuous enhancement of people's awareness of environmental protection, thermal insulation and energy saving become the focus of daily life.Building insulation material glass wool coruscate new machine, has been used in building engineering exterior wall insulation, air conditioning pipe insulation and energy saving and other fields.Especially in chemical, electric power, petroleum and other high temperature industrial applications, plays an immeasurable role, not only to protect the stability of the system, but also to ensure the safety of personnel.

 Building insulation material

Glass wool is composed of glass fiber interwoven together through a porous fiber structure. It takes glass as the main raw material, supplemented by other materials, such as bounce sand, quartz sand, dolomite, etc., after melting state, it is imported into the centrifuge and produced by centrifugal process.

Glass fiber is a kind of inorganic non-metallic material with excellent performance, and there are many kinds of glass fiber. It has the advantages of good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but the disadvantage is that it is brittle and has poor wear resistance.It is made of glass balls or waste glass as raw materials by high temperature melting, drawing, winding, weaving and other processes, the diameter of the monofilament is a few microns to twenty meters of microns, equivalent to a hair 1/20-1/5, each bundle of fiber is composed of hundreds of or even thousands of monofilament.Glass fiber is usually used as reinforcement materials in composite materials, electrical insulation materials and thermal insulation materials, electric roadbed board and other fields of the national economy.

The main composition of silica, alumina and boron oxide and magnesium oxide, calcium oxide, sodium oxide, etc., according to the amount of alkali content, in the glass can be divided into non-alkali glass fiber (0% ~ 2% sodium oxide, aluminum borosilicate glass), the alkali glass fiber (8% ~ 12% sodium oxide, boron or boron sodium calcium silicate glass) and high alkali glass fiber (more than 13% sodium oxide, sodium calcium silicate glass).

Therefore, glass wool is a kind of amorphous inorganic non-metallic material, its main component is silica and other oxides.Therefore, it has the performance characteristics of inorganic materials, high melting point, wear resistance, corrosion resistance, etc.Similarly, glass wool itself also has the performance characteristics of heat preservation, energy saving, sound absorption and heat insulation. It has become a kind of thermal insulation material with excellent performance. It participates in the application solutions of thermal insulation material industry in all walks of life, such as aerospace, cold chain logistics, artificial intelligence, big data cloud computing and so on, and promotes the progress and development of social technology.
