The zirconia ceramic rod/plunger is made of 3mol yttria-stabilized zirconium oxide (YSZ) material, showing the characteristics of high density, high hardness, and never wear. Its hardness is usually above HRA95, which is dozens of times that of metal materials. Features of zirconia ceramic plunger:
-Corrosion acid and alkali resistance
-Ceramic plunger adopts high-performance technical ceramic material, which has the properties of high hardness, wear resistance, high-temperature resistance, and corrosion resistance. Ensure reliable material performance.
-The microporous structure obtained by the unique processing method on the working surface of the ceramic plunger has a self-lubricating effect, which changes the sliding friction and lubrication mechanism of the traditional plunger pump.
-The inner cavity surface adopts a fluid structure without dead corners and grooves. The inner cavity surface and the plunger surface are processed to a mirror surface by advanced high-precision internal and external cylindrical grinders, and the outer surface is vibrated and polished for easy cleaning and disinfection.
Zirconia ceramic plungers are more wear-resistant than cemented carbide, and have the advantages of corrosion resistance, non-magnetic and non-conductive properties, self-lubricating properties, and green environmental protection that cemented carbide does not have. It does not oxidize when working in a certain high-temperature environment. Our company’s ceramic plungers can be free of color spots on the surface and have no visible pores to the naked eye. Zirconia not only has the advantages of high hardness, high wear resistance, and high-temperature resistance but also does not oxidize when working in a certain high-temperature environment. Zirconia ceramics are also a very tough material among fine ceramics, so it is often used in structural parts and wear-resistant parts. Because of its jade-like texture, it is also widely used in daily ceramics.
Tests have shown that the high wear resistance of zirconia ceramic plungers is much higher than that of traditional metal plungers. It is an ideal alternative to metal plungers and greatly extends the service life of related parts. This is also related to its unique manufacturing process. The microporous structure obtained by the unique processing method on the working surface of the zirconia ceramic plunger has a self-lubricating effect, which changes the sliding friction and lubrication mechanism of traditional plunger pumps.
In addition, the inner cavity surface of the zirconia ceramic plunger adopts a fluid structure without dead corners or grooves; the inner cavity surface and the plunger surface are matched, and the high-precision internal and external cylindrical grinder is used to process them to a mirror surface, and the outer surface is vibrated and polished, which is convenient for cleaning and disinfection.
Compared with metal plungers, zirconia ceramic plungers are not only more durable, but also have better use effects, and can meet the application requirements under some special working conditions.
