Diamond machining for 0.03mm concentricity zirconia ceramic rods
Description:
The ceramic plunger is mainly applicable to petroleum industry, chemical industry, food industry, which is used to replace the metal plunger and solve the problems of poor corrosion resistance, low-temp resistance, short service life. It has high performance of wear-resistance, corrosion-resistance and shock resistance. Compared with metal plunger, the service life of ceramic plunger is 6-10 times longer. Ceramic plunger can not only greatly improved the output of crude oil, but also reduce the cost of viscous oil production.
Zirconium oxide ceramics have the highest toughness and strength at room temperature of all the advanced ceramic materials. It also has high thermal expansion, low thermal conductivity and high resistance to corrosion. Its unique resistance to crack propagation and high thermal expansion make it an excellent material for joining ceramics and metals such as steel.
