The production cost of alumina wear-resistant ceramics is high. In order to reduce the production cost, the following aspects can be considered: I. Raw material selection 1. Select cost-effective raw materials: Under the premise of ensuring product quality, select alumina powder with relatively low price but satisfactory performance, such as industrial alumina or calcined alumina instead of high-purity alumina powder. At the same time, we can explore the use of a mixture of alumina and other ceramic materials to reduce costs through reasonable proportions. 2. Joint procurement of raw materials: Cooperate with multiple companies for joint procurement and use economies of scale to reduce procurement costs. II. Process optimization 1. Optimize the preparation process: Improve production efficiency, reduce energy consumption and waste generation by improving the preparation process. For example, use advanced sintering technology and mold design to shorten sintering time and reduce energy ...
Chemshun Dovetail wear-resistant ceramic lining is a wear-resistant lining fixed to the surface of the equipment through a dovetail structure. It is mainly used to prevent internal wear of the equipment. Its design achieves firm mechanical fixation through the clamping of the dovetail guide rail and the ceramic lining 1) Structural features Dovetail design: stable installation through clamping, fits the surface contour of the equipment, reduces stress concentration, and adapts to complex working conditions such as high temperature vibration Ceramic material: mainly alumina ceramic, high hardness (HRA ≥ 82), strong wear resistance, high temperature resistance (about 750 ° C), corrosion resistance 2) Advantages High wear resistance: Made of high-purity aluminum oxide silicon nitride and other raw materials, it has high hardness and strong wear resistance Corrosion resistance: It can resist the erosion of chemical substances such as acids, alkalis and salts, and is suitable ...
In the field of industrial wear-resistant materials, alumina ceramics hold a significant position due to their excellent wear resistance. This performance is not accidental; it is the result of the combined effect of a series of unique material properties. From the microstructure to the macroscopic properties, each characteristic provides a solid foundation for its wear resistance. High hardness is the core foundation of the wear resistance of alumina ceramics. The Mohs hardness of alumina ceramics reaches up to level 9, which is only second to diamond (level 10) and cubic boron nitride. It is much higher than that of ordinary metal materials (such as the Mohs hardness of steel is only 4-5 levels). In friction or impact scenarios, high hardness means that the material surface is less likely to be scratched or crushed. When hard particles or objects come into contact with the surface of alumina ceramics, the ceramic surface can resist deformation by virtue of its high hardness, reducin...
