Sander is no stranger to us. Its mission is grinding. A good Sander has the advantages of high grinding efficiency, stable equipment function and high product quality.
In order to ensure these advantages, it is necessary to put forward requirements for its accessories: firstly, it has wear resistance function, that is, low wear rate during grinding, and will not cause serious pollution to the grinding product; The efficiency of grinding can only be guaranteed when the hardness is high enough. At present, only ceramic parts can meet these two very important needs, and zirconia ceramic parts are partners of Sander.
Among ceramic parts, zirconia is a kind of widely used ceramic parts, and also a kind of complex ceramic parts used in Sander. Among the four kinds of diamond materials with complex technology, zirconia, alumina, silicon carbide and silicon chloride have better oxidation resistance. In high-speed rotating Sander, the advantages of being a rotor are more and more obvious. Due to the high-speed rotation process, during the contact and grinding process between the rotor and the material, it is easy to cause cracks in ceramic parts, which can occur overnight. Only zirconia ceramics can meet the durability of this special application condition.
In addition, no matter what material the rotor is made of, impurities will occur after grinding, but the impurity content of ceramic parts is very low compared to traditional steel and polyurethane because they have excellent wear resistance.
Common zirconia accessories
1) Rotor: the rotating body supported by the rotating shaft in the Sander. During the production process, driven by the grinding rotor, the grinding medium and slurry achieve particle dispersion and grinding damage through the grinding effect.
Filter screen: Multiple pieces can be spliced into a straight tube structure for discharge.
Grinding inner cylinder: The grinding inner cylinder made of zirconia material not only has high strength and hardness, but also is wear-resistant and corrosion-resistant.
