First of all, glass wool is not asbestos.
Asbestos is a mineral that the state has banned because of its carcinogenic effects. Asbestos also known as "stone cotton", for commercial terms, refers to a high tensile strength, high flexibility, chemical resistance and heat erosion, electrical insulation and can be spun silicate mineral products. It is the general name for a naturally fibrous silicate mineral.
And glass woolis a kind of inorganic glass fiber, the raw material is quartz stone, glass slag, etc., after 1350 degrees Celsius high temperature melting, the use of centrifuge centrifugal cast uniform slender glass fiber. Glass wool is a kind of thermal insulation material with high cost performance in line with national standards. And although asbestos once was used as building materials likewise, heat preservation effect is beautiful, but its harm to human body is irreversible, cause cancer, respiratory tract disease is phased out gradually thereby.
Because asbestos and glass fiber appearance shape, performance, use, although are very similar, but both components are different, different structure, asbestos fiber is crystalline fiber, and glass fiber is amorphous amorphous structure, asbestos fiber can crack along the axis into a finer fiber, this point is vital to human health impact.
At present, glass wool products are widely used in thermal insulation industry, its application fields in construction, industry, manufacturing industry, pipeline transportation and other aspects. In order to respond to the appeal of the national energy conservation and environmental protection, Uetersen Group also developed formaldehyde-free glass wool, reduce formaldehyde emissions, in densely populated places, the use of formaldehyde-free glass wool, avoid inhalation of formaldehyde, phenol, become "humanoid formaldehyde removal machine". High quality glass wool, in the process of installation and use, less dust, thin and uniform glass fiber, good insulation effect, easy to cut dressing. The selection of qualified glass wool is also the primary guarantee of safety and quality.
In addition to being used as heat preservation, glass woolis also used in combination with other materials, such as some sound-absorbing walls. The sound-absorbing material also contains glass wool. As a multi-gap material, glass wool can effectively absorb middle and high frequency sound waves, reduce the rebound transmission of noise, and cause discomfort and fatigue caused by noise.
