Comparison of advantages between zirconia ceramics and alumina ceramics:

Ceramic toughness comparison:

The toughness of zirconia ceramics is four times that of alumina ceramics. At the same time, zirconia falls freely from a height of one meter, but there are some gaps and alumina will break.

Density comparison:

The density of zirconia ceramics is twice that of alumina ceramics. In contrast, zirconia has better compressive properties.

Friction coefficient comparison:

The friction coefficient of zirconia ceramics is only 1 / 2 of that of alumina ceramics, while the friction coefficient of alumina ceramics is very low. In the actual use process, more elastic wear and hard wear should be considered. The specific kind of material can be wear-resistant depends on the actual use.

Density comparison:

The density of zirconia ceramic structure is higher than that of alumina ceramic. The density of alumina ceramic is 3.5, and the density of zirconia ceramic structure is 6. The texture is more delicate. After grinding, the surface finish is higher, up to ▽ 9 or more. It is mirror like, extremely smooth and has smaller friction coefficient.

Surface finish contrast:

Zirconia ceramic structural parts have higher surface finish, mirror like, extremely smooth, and less friction with the mesh, which can further improve the service life of the mesh, greatly reduce the mesh consumption, reduce the paper mesh current and reduce the power consumption. In addition, the toughness of zirconia ceramic structural parts is excellent, which overcomes the inherent brittleness of ceramics, has higher wear resistance, greatly prolongs the service life of products, and significantly improves the quality of paper.

Zirconia ceramic structure is a very important structural ceramic developed recently, which is second only to alumina ceramic. Because of its good properties (such as its fracture toughness is higher than that of alumina ceramics), zirconia ceramic structures have attracted more and more attention.
