What is the fire resistance of asbestos?
A little fire is good, and a fire is not necessary.
The fire performance of asbestos is very good, generally below 300 DEG C heating 2 hours less weight loss, if 2 hours of heating in the temperature of above 1700 DEG C, chrysotile fiber weight loss more, other types of asbestos fiber less weight loss.Asbestos is of high fire resistance, electrical insulation and thermal insulation. It is an important fireproof, insulating and heat insulating material. When the thermal conductivity of asbestos fiber is 0.104 ~ 260 card / meter degree, the conductivity is very low, and it is a good insulation material of heat and electricity.Asbestos, also known as asbestos, is a commercial term for silicate mineral products with high tensile strength, high flexibility, chemical and thermal resistance, electrical insulation, and spinnability. It is a general term for natural fibrous silicate minerals. Under the jurisdiction of the 2 class a total of 6 kinds of minerals (with serpentine asbestos, amphibole asbestos, asbestos, actinolite anthophyllite tremolite asbestos asbestos, iron, etc.). Asbestos consists of a fiber bundle, consisting of very long, very thin fibers that can be separated from each other. Asbestos is of high fire resistance, electrical insulation and thermal insulation. It is an important fireproof, insulating and heat insulating material. However, because asbestos fibers can cause asbestos, pleural mesothelioma and other diseases, many countries have chosen to ban the use of such dangerous substances.
