Non asbestos rubber sheet, non asbestos rubber sheet, temperature resistance, how many degrees?
2. Asbestos sealing material has higher mechanical strength than asbestos free sealing material(1) surface of asbestos fibers with multivalent metal cations, and the surface with negative charge to form a solid rubber interface, improve the bonding strength of glue fiber, which improves the mechanical strength of asbestos sealing material. And all the non asbestos mineral fiber and rubber matrix direct affinity are not as good as asbestos therefore, the bonding strength of glue fiber than asbestos.(2) asbestos fiber can be broken almost infinitely, and its specific surface area is larger than that of non asbestos mineral fiber, so the effect is obvious(3) the tensile strength of asbestos fiber is higher than that of non asbestos fiber, so the strengthening effect of asbestos fiber is obvious
3, non asbestos sealing material than asbestos sealing material good densification. Because the filler content of non asbestos sealing material and the particle size is not high, can full packing rubber fiber micro gap. In addition, non asbestos fiber like asbestos fiber that has a tubular structure, but the solid structure, the compact is better.4, non asbestos sealing material is environmentally friendly, non asbestos sealing material is environment-friendly. Asbestos materials comprising the asbestos fiber seal is easy to produce human silicosis, and non asbestos sealing material does not contain asbestos fibers.5, as everyone knows, the severity of asbestos material harm to human health, in Europe and Japan and other developed countries have banned the use of asbestos, and our country will gradually eliminate asbestos sealing material is replaced by non asbestos sealing materialAsbestos, 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.
1. What is the difference between asbestos sealing material and asbestos free sealing material? Why?Answer: 1, asbestos sealing material than non asbestos sealing material with high temperature resistance. The main component of asbestos sealing material is asbestos, asbestos filler and rubber, and fillers which temperature is very high; most non asbestos sealing material is the main component of mineral fiber, organic fiber, filler and rubber, wherein the temperature resistance of organic the fiber at 200 degrees Celsius.
