The ductile domain grinding, one of the grinding methods of zirconia ceramics, was introduced above. Next, Pintejin Ceramics Factory will continue to introduce the second grinding method, laser preheat-assisted grinding. The middle hexagonal dividing line zirconia ceramic has the common characteristics of high hardness, high brittleness and low fracture toughness of ceramic materials, which makes it easy for ceramic materials to produce deformed layers, surface/subsurface microcracks, material powdering, Defects such as fuzzy surfaces, phase transition regions, and residual stress limit the further expansion of the application range of ceramic materials. Ceramic materials, especially those with higher hardness, such as zirconia ceramics, have always been “hard to process”, so that the Read more

EDM mainly produces high-temperature melting and vaporization of materials through discharge between electrodes. Therefore, the machinability of materials mainly depends on the thermal properties of materials, such as melting point, specific heat, thermal conductivity, etc., while the mechanical properties of materials have little influence. . EDM is suitable for the machining of superhard conductive materials. Since most ceramic materials are electrical insulators, electrical discharge machining was rarely used in the past. But in recent years, many high-performance ceramics contain conductive materials such as TiC, which makes EDM possible. (1) Processing of conductive ceramics A considerable part of ceramics has a certain degree of conductivity, so it can be directly processed Read more

Introduction of rotary valve type zirconia ceramic liquid injection pump Zirconia ceramics is a material with excellent corrosion resistance and wear resistance. The ceramic liquid injection pump is widely used in batteries, medicine, electronics, machinery, chemical textiles and other industries with the help of the excellent performance of zirconia ceramics. The rotary valve type zirconia ceramic liquid injection pump is generally a centrifugal pump. Its impeller, volute, shaft seal cavity and suction and discharge pipes are all made of zirconia ceramic material. It is mainly used to transport strong corrosive liquids such as hydrochloric acid, sulfuric acid and nitric acid. , can not transport fluorine-containing materials and concentrated lye. The Read more

The damage of the ceramic plate is mainly caused by the unstable propagation of cracks. The action of the tool tip during machining will leave a certain degree of sharp machining marks on the machined surface, resulting in small crack defects and stress concentration, reducing The fatigue strength of structural ceramic parts affects the electrical and magnetic properties of functional ceramic plates. Therefore, ultra-precision machining of ceramic plates must be carried out to reduce small crack defects and stress concentration, and to improve the fatigue strength of parts. Usually, the high-precision machining that reaches or exceeds the accuracy limit of this era is called ceramic ultra-precision machining. In the 1980s, Read more

Zirconia ceramic binders Wax-based or oil-based binders, water-based binders and solid polymer solutions. Zirconia ceramic wax-based binders usually contain 3-4 components, and the polymer controls the flow viscosity, green product (green body before sintering) strength and degreasing characteristics. The short molecular chains have good forming properties and can minimize orientation effects in the forming element. Zirconia wax or oil is the main filler and is removed during the initial stage of degreasing. Zirconia ceramic surfactants are used to improve the compatibility of powders with binders. Zirconia ceramic plasticizers are used to adjust the flow properties of polymers. Zirconia ceramic water-based binders contain water-soluble polymers, gels or water glass. This type Read more
