The toughness difference:
The toughness of zirconia ceramics is 4 times that of alumina ceramics. At the same time, when zirconia is dropped freely from a height of one meter, there will be some gaps and the alumina will be broken.
Difference in density:
The density of zirconia ceramics is twice that of alumina ceramics, and the compressive properties of zirconia are better.
The difference in friction coefficient:
The friction coefficient of zirconia ceramics is only 1/2 of that of alumina ceramics, while the friction coefficient of alumina ceramics itself is very low. In actual use, more consideration should be given to elastic wear and hard wear. The specific wear-resistant material depends on the actual use situation.
The difference in density:
The density of zirconia ceramic structural parts is higher than that of alumina ceramics, the density of alumina ceramics is 3.5, the density of zirconia ceramics is 6, and the texture is more delicate. , is mirror-like, extremely smooth, and has a smaller coefficient of friction.
Differences in surface finish:
Zirconia ceramic structural parts have higher surface finish, mirror-like smoothness, and less friction with the mesh, which can further improve the service life of the mesh, reduce mesh consumption, reduce paper mesh current, and reduce electricity consumption. In addition, the toughness of the zirconia ceramic structure is good, which overcomes the inherent brittleness of the ceramic itself, has higher wear resistance, prolongs the service life of the product, and significantly improves the quality of paper.
Zirconia ceramics is a very important structural ceramics recently developed after alumina ceramics. Because of some of its good properties (such as its fracture toughness is higher than that of alumina ceramics), zirconia ceramics have attracted more and more attention.
