Ống lót gốm alumina chống mài mòn có độ cứng cao cho ngành khai thác than và nhà máy xi măng

Mô tả Sản phẩmProduct OverviewThe alumina ceramic tubes produced by our company are made of stable quality alumina raw materials and are sintered through mature molding processes (such as dry pressing, isostatic pressing or extrusion) and high-temperature tunnel kilns. This series of products has a good balance in high temperature strength, insulation performance and chemical stability. It is an important component in the fields of thermal equipment, wear-resistant transmission and electronic power in modern industry.Technical Features1.Excellent temperature resistance: Depending on the purity, it can be used for a long time in the range of 1400°C to 1700°C, with low thermal shrinkage. 2.Reliable mechanical strength: It can still maintain good structural strength and load-bearing capacity in high temperature environments, and is not easy to deform. 3.Good insulation resistance: It has high volume resistivity and can effectively insulate in complex electrical environments. 4.Resistance to chemical attack: It can resist the erosion of various acid and alkali environments (except hydrofluoric acid), and has good non-wettability to various metal melts. 5.Surface quality: Provide rough burnt surface, fine grinding surface or polished surface to meet different sealing and assembly accuracy requirements.Applications1.Thermal equipment: thermocouple protection sleeves, laboratory tube furnace tubes, heating element brackets. 2.Power electronics: power resistor base materials, high-voltage ceramic tube shells, vacuum tube insulation parts. 3.Fluid engineering: Wear-resistant pump valve linings, sandblasting nozzles, corrosive medium transportation pipelines. 4.Paper and textile: high-speed wire guides, wear rings and bushings.Specification
