The advantages of the two materials of ceramic tube using zirconia and alumina:
Ceramic toughness comparison:
The toughness of zirconia ceramics is 4 times that of alumina ceramics. At the same time, zirconia falls freely from a height of one meter, but only some gaps will be broken.
Density comparison:
The density of zirconia ceramics is twice that of alumina ceramics. In contrast, zirconia has better compression resistance.
Friction coefficient comparison:
The friction coefficient of zirconia ceramic is only 1/2 of that of alumina ceramic, and the friction coefficient of alumina ceramic itself is very low. In actual use, more consideration is given to the elastic and hard wear. The specific kind of material can wear depends on the actual use.
Comparison of 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 ceramic structural parts is 6, the texture is more delicate, after grinding, the surface finish is higher, up to ▽ Above 9, it is mirror-like, extremely smooth, and has a smaller friction coefficient.
Surface finish comparison:
The surface of the zirconia ceramic structural parts has a higher surface finish, is mirror-like, extremely smooth, and has less friction with the net, which can further increase the service life of the net, greatly reduce the net consumption, reduce the current of the net part, and reduce the power consumption. . Another e799bee5baa6e59b9ee7ad9431333365636635 external zirconia ceramic structural parts have excellent toughness, overcoming the inherent brittleness of the ceramic itself, higher wear resistance, product life is greatly extended, and paper quality is significantly improved.
Zirconium oxide ceramic structure is a very important structural ceramic that has been developed recently, second only to alumina ceramics. Because of some good properties (such as its fracture toughness is higher than that of alumina ceramics), zirconia ceramic structural parts are getting more and more attention.
In general, zirconia is more wear-resistant and corrosion-resistant than alumina. The ceramic tube adopts zirconia material to transport particles and corrosive liquid better.
