Introduction of a high-temperature mica tube, characteristics and uses of Yangzhou Dongxin Electric Co. Mica tube is made of high quality paper or muscovite mica paper with a hard right after high performance silicone adhesive volume processing of baking together The tubular mass of insulating material. It has good electrical insulation properties and high mechanical strength for iron and steel, metallurgy and other high-temperature furnace and a variety of electrical appliances, motors, electric smelting furnace and other equipment in the electrode rod bushing or high temperature insulation. Compared with the traditional ceramic, mica tube has a wall thickness and ovality easy to control, discharge evenly, not broken, etc., is an ideal substitute for part of the ceramic tube. I plant the production of mica tube surface is smooth, the size of the error is small, round, good, high strength is known, has a high temperature, high strength, high precision, we can process according to customers drawing any difficult mica tube products. Second, the specification is divided into muscovite mica tube pipe and gold mica tube temperature 800-1000 ℃. I plant the production of mica tube length between 10-1000mm, inner diameter 8-300mm, special specifications can be produced according to a user-supplied drawings mica tube. (Example slotting, bonding, etc.). Third, the special specifications mica tube can be kind to map processing. Fourth, the inner and outer diameter deviation (mm) nominal inside diameter outer diameter deviation deviation <10 ± 0.3 ± 0.4 10-20 ± 0.4 ± 0.5 21-50 ± 0.5 ± 0.7 51-100 ± 0.6 ± 1.0 101-200 ± 0.8 ± 1.2 201-300 ± 1.0 ± 1.5
