The use of enamel products is closely related to its performance. Widely used in daily life, medical treatment, architecture, and various industrial areas. Because of the good mechanical performance, abrasion resistance (Mohs hardness 8), pressure, can be made into the ship's propeller bearing sleeve, etc.. Because of stable chemical properties, can resist organic acids, inorganic acid and alkali corrosion, used in the production of chemical industry in the reaction pot, reaction tower, is an indispensable chemical industry in the anti-corrosion materials. The thermal performance is stable, and can be made into the exhaust pipe of the automobile, the tractor and the train, the industrial chimney, the high temperature resistant parts of the aircraft and the rocket, and the material of the radiation source in the atomic energy technology. The insulation is good, can be used for high frequency high voltage insulation coating, motor, transformer etc..
