The comparison of zirconia ceramic rod and alumina ceramic roller is introduced briefly.

Toughness comparison of ceramics:

The toughness of zirconia ceramic rod is four times that of alumina ceramic roller. At the same time, it falls freely from a height of one meter. Zirconia will only have some notches, while alumina will break down.

Density comparison:

The density of zirconia ceramic rod is twice that of alumina ceramic roller, and the compressive performance of zirconia ceramic rod is better than that of alumina ceramic roller.

Friction coefficient comparison:

The friction coefficient of zirconia ceramic rod is only 1/2 of that of alumina ceramic roller, while the friction coefficient of alumina ceramic roller itself is very low, so elastic wear should be taken into account more in practical use. Specific which material can wear-resistant depends on the actual use.

Density contrast:

The density of zirconia ceramic rod structure is higher than that of alumina ceramic roller. The density of alumina ceramic roller is 3.5. The density of zirconia ceramic rod structure is 6. The texture of zirconia ceramic rod structure is more delicate. After grinding, the surface of zirconia ceramic rod structure has higher smoothness, mirror shape and lower friction coefficient.

Surface finish comparison:

Zirconia ceramic rod structure has higher surface finish, mirror-like, very smooth, and less friction with the network. It can further improve the service life of the network, greatly reduce network consumption, reduce network current and reduce power consumption. In addition, the toughness of zirconia ceramic rod structure is excellent, which overcomes the inherent brittleness of the ceramic itself, has higher wear resistance, prolongs the service life of the product greatly, and improves the quality of the paper obviously.

Zirconia ceramic rod structure is a very important structural ceramics developed recently, which is second only to alumina ceramic roller. Because of its good properties (such as its fracture toughness is higher than that of alumina ceramic roller), more and more attention has been paid to the structural parts of zirconia ceramic rod.
