Asbestos material and its specific surface area - Database & Sql Blog Articles

Asbestos material and its specific surface area test Asbestos, also known as "asbestos", is a commercial term referring to silicate minerals with high tensile strength, high flexibility, chemical and thermal attack resistance, electrical insulation and spinnability. product. It is a general term for natural fibrous silicate-like minerals. Under the jurisdiction of 2 categories, a total of 6 kinds of minerals (with serpentine asbestos, amphibole asbestos, actinolite asbestos, asbestos asbestos, iron asbestos, tremolite asbestos, etc.). Asbestos consists of bundles of fibers, which in turn are composed of very long, thin fibers that can be separated from one another. Asbestos is highly resistant to fire, electrical insulation and thermal insulation and is an important fire, insulation and insulation material.
Asbestos is a general term for six natural fiber minerals with commercial use. The term asbestos is not mineralogical, but a commercial term for mineral products with high tensile strength, high flexibility, chemical and thermal attack resistance, electrical insulation and spinnability. Asbestos consists of bundles of fibers, which in turn are composed of very long, thin fibers that can be separated from one another. Asbestos can be divided into two types: serpentine asbestos (chrysotile) and amphibole.
Asbestos has been used for weaving very early. China's Zhou Dynasty has been able to make fabrics from asbestos fibers. Because it is burnt, it is as white as new, so it is called fire cloth or fire cloth. Asbestos is highly resistant to fire, electrical insulation and thermal insulation and is an important fire, insulation and insulation material. At present, there are nearly 3,000 kinds of asbestos products or products containing asbestos, which are mainly used for mechanical transmission, braking, heat preservation, fire prevention, heat insulation, anti-corrosion, sound insulation, insulation, etc. Among them, automotive, chemical, electrical equipment and construction are more important. Industry and other manufacturing departments.
Specific surface area is one of the important indicators for evaluating the utilization of catalysts, adsorbents and other porous materials such as asbestos, mineral wool, diatomaceous earth and clay minerals. The specific surface area of ​​asbestos has obvious influence on its thermal properties, adsorption capacity, chemical stability and degree of cotton opening.
