Comparison of friction coefficient:
The friction coefficient of zirconia ceramics is only 1/2 of that of alumina ceramics, and the friction coefficient of alumina ceramics is very low. In actual use, it is more necessary to consider the amount of elastic wear and hard wear. The specific material that can be worn depends on the actual use.

Zirconia ceramic structure has a higher surface finish, is mirror-like, extremely smooth, and has less friction with the net, which can further increase the life of the net, greatly reduce the net consumption, reduce the current of the net portion of the paper, and reduce electricity . In addition, the toughness of zirconia ceramic structural parts is excellent, which overcomes the inherent brittleness of the ceramic itself, has higher wear resistance, greatly prolongs the service life of the product, and significantly improves the paper quality.

Ceramic toughness comparison:
The toughness of zirconia ceramics is 4 times that of alumina ceramics. At the same time, zirconia is freely dropped from a height of one meter, but there will be some gaps.
Density comparison:
Zirconia ceramics are twice as dense as alumina ceramics.
Density comparison:
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 ceramic structures is 6. The texture is more delicate. Above 9, it is mirror-like, extremely smooth, and has a smaller friction coefficient.
Comparison of surface finish:
Zirconia ceramic structural part is a very important structural ceramic newly developed next to alumina ceramics. Because of some of its good properties (such as its fracture toughness higher than alumina ceramics), zirconia ceramic structural parts have received increasing attention.
