I want the material with poor thermal conductivity and aging resistance. It's used for instruments. I'm afraid it's hot. I think the asbestos is probably suitable for my needs! Thank you ~
There are many kinds of asbestos, which can be divided into two kinds: serpentine asbestos and amphibole asbestos according to their mineral composition and chemical composition. Chrysotile asbestos, also called chrysotile asbestos, is one of the most productive asbestos. It has good spinnability. Amphibole asbestos can be divided into blue asbestos, asbestos tremolite, actinolite asbestos, chrysotile is less than the yield.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.
4. Asbestos rubber productsAsbestos rubber products are mainly used for sealing and lining of various equipments. The main varieties include: Oil asbestos packing, oil asbestos, graphite packing, other asbestos packing, asbestos rubber plate, oil resistant plate, etc.. The largest production is the ordinary asbestos rubber sheet (high, medium, low pressure) and oil resistant board, its grades are as follows.Asbestos rubber products are generally made of chrysotile asbestos, and different grades are chosen according to their grades.Properties of asbestos rubber sheetsVariety grade, surface color, condition of useOrdinary asbestos rubber sheet XB-450XB-350XB-200 Brown BlackRedNatural medium, pressure 588 * 104Pa, temperature 450 DEG COrdinary medium, pressure 392 * 104Pa, temperature 350 DEG COrdinary medium, pressure 147 * 104Pa, temperature 200 DEG COil resistant asbestos rubber sheet 400#300#250# red brownSky blueBlack brown oil medium, pressure 392 * 104Pa, temperature 400 DEG COil medium, pressure 294 * 104Pa, temperature 300 DEG COil medium, pressure 147 * 104Pa, temperature 200 DEG C
