Many customers who have needs for ceramic tubes
do not know whether to choose alumina or zirconia. As a professional manufacturer of ceramic structural parts for more than ten years, Mingrui Ceramics will explain the differences between ceramic tubes using zirconia or alumina and what is the difference between them, which material is more wear-resistant and anti-corrosion.
ceramic tubes made of alumina and zirconia
Comparison of the advantages of ceramic tubes using zirconia and alumina:
1. Comparison of ceramic toughness:
The toughness of zirconia ceramics
is 4 times that of alumina ceramics
. At the same time, zirconia can be dropped freely from a height of one meter, but there will be some gaps in the alumina and it will break.
The density of zirconia ceramics is twice that of alumina ceramics, and zirconia has better compression resistance.
3. 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, elastic wear and hard wear should be considered. The specific kind of material can be wear-resistant depends on the actual use.
4. Comparison of Relative Density :
The density of zirconia ceramic structural parts is higher than that of alumina ceramics. The density of alumina ceramics is 3.5, and the density of zirconia ceramic structural parts is 6. The texture is more delicate. After grinding, the surface finish is higher, reaching ▽ More than 9, it is mirror-like, extremely smooth, and has a smaller friction coefficient.
5. Comparison of surface finish:
The surface finish of zirconia ceramic structural parts is higher, it is mirror-like, extremely smooth, and the friction between it and the net is smaller, which can further improve the service life of the net, greatly reduce the power consumption of the net, reduce the current of the paper net, and reduce the power consumption . In addition, the toughness of the 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 quality of the paper.
Zirconia ceramic structural parts are a newly developed very important structural ceramics second only to alumina ceramics. Due to some of its good properties (such as its fracture toughness higher than that of alumina ceramics), zirconia ceramic structural parts have attracted more and more attention.
Generally speaking, zirconia is more wear-resistant and corrosion-resistant than alumina, and ceramic tubes made of zirconia can better transport particles and corrosive liquids.
