Performance advantages of zirconia ceramics Application of zirconia ceramics

Dongguan Kezhong Ceramic is a professional manufacturer of zirconia ceramics. The zirconia ceramics produced have the characteristics of light weight, high hardness, good heat resistance, and good wear resistance. The wear resistance of ceramic working surfaces is more than 100 times that of manganese steel and 20 times that of high chromium cast iron;

It is several to several tens of times higher than wear-resistant rubber. The ceramic metal bonding strength can reach 300kg/cm2, and the service temperature can reach 500 ℃. The service life of equipment made of wear-resistant ceramics can be increased by more than five times, and the performance price ratio can be increased by more than three times.

The main application range of zirconia ceramics is wide: it is mainly used in various equipment for conveying various high hardness and high wear granular materials, including various mechanical equipment in industries such as power, heat, steel, coal, cement, mining, smelting, petroleum, building materials and chemical industry, fan, papermaking, machinery, powder engineering, grain machinery, tobacco, etc.

According to the different bonding methods with the metal substrate, it can be used on the inner surface of stationary components, such as pipelines, elbows, separators, chutes, valves, various shells, etc., and can also be used on high-speed rotating equipment, such as various fan rotors, impellers, drums, etc.

Zirconia ceramics are also known as precision wear-resistant ceramics, special wear-resistant ceramics, or high-tech wear-resistant ceramics. It is a wear-resistant ceramic that uses highly selected raw materials and is produced according to special manufacturing processes, with precise control of chemical composition and excellent performance.

At present, zirconia ceramics are mainly used in high technology and industry, such as microelectronics, nuclear reactors, aerospace, Magnetohydrodynamic generator, artificial bones and artificial joints.

Japan used zirconia ceramic as the ignition plug for internal combustion engines as early as the 1950s. In the future, it will be used for production in small and complex parts one after another.

In recent years, people have actively engaged in the development and research of various heat-resistant and wear-resistant parts, for example, the swirl chamber head of diesel engines has achieved wear-resistant ceramics.

Among all ceramic materials, zirconia ceramics have extremely high resistance to general corrosion and abrasion, and have the highest cost performance ratio, making them suitable for most applications. Zirconia wear-resistant ceramics can be used as lining pipe fittings:

Including straight pipes, bends, elbows, reducers, square and circular transition nipples of various pipe diameters; It utilizes the principle of ceramic metal composite production technology, through bonding, welding, inlaying, riveting, and socket connection technology, to composite various wear-resistant ceramic sheets and block brick materials on the worn surface of the pipe fittings, forming a surface layer with excellent wear resistance, while the matrix still uses ordinary metal materials for composite pipe fittings.

Compared with traditional all metal high alloy pipe fittings, the working surface has higher wear resistance, which can increase the overall wear resistance and anti-corrosion service life of the pipe fittings by several to dozens of times. The overall weight has decreased significantly, reducing the amount of steel used, reducing the cost of equipment and maintenance, and improving economic efficiency.
