Advantages of zirconia ceramics and alumina ceramics

2019-09-14 13:04

Comparison of the advantages of zirconia ceramics and alumina ceramics:

Ceramic toughness contrast:

The toughness of zirconia ceramics is four times that of alumina ceramics, and that zirconia is free to fall from a height of one meter, and only some of the notched alumina will be broken.

Density comparison:

The density of zirconia ceramics is twice that of alumina ceramics, compared to the better compressive properties of zirconia.

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 itself is very low. In actual use, the elastic grinding amount and the hard grinding amount are more considered. The specific material can be worn according to the actual use.

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 structural parts is 6, and the texture is finer. After grinding, the surface finish is higher, up to ▽ 9 or more, it is mirror-like, extremely smooth, and has a smaller friction coefficient.

Surface finish contrast:

The surface finish of zirconia ceramic structural parts is higher, mirror-like, extremely smooth, and the friction between the mesh and the mesh is smaller, which can further improve the service life of the net, greatly reduce the net consumption, reduce the current of the paper net, and reduce the electricity consumption. . In addition, the toughness of the zirconia ceramic structural member is excellent, overcomes the inherent brittleness of the ceramic itself, the wear resistance is higher, the service life of the product is greatly prolonged, and the paper quality is obviously improved.

Zirconia ceramic structural members are a very important structural ceramic that has recently been developed, which is second only to alumina ceramics. Due to its good properties (such as its fracture toughness is higher than alumina ceramics), zirconia ceramic structural parts have received more and more attention.
