Nowadays, the ceramic industry has developed rapidly in all walks of life. Industrial ceramics have been widely used in many industries in recent years due to their superior characteristics. Among them, zirconia ceramics and alumina ceramics are the most common ones. The characteristics of these two types of ceramics have their own advantages. Many companies do not know how to choose zirconia ceramics and alumina ceramics. Today, Dongguan Mingrui Ceramic Technology Co., Ltd. has a large number of technical staffHome introduction:
Dongguan Mingrui Ceramic Technology Co., Ltd. is a development-oriented enterprise established based on years of technological accumulation in the development of ceramic materials. It has experience in the manufacturing technology, post-processing technology and market application development of many types of special ceramic materials. Many unique innovations. In the fields of superhard ceramics, soft ceramics and functional ceramics, we bring value beyond expectations to individual customers and corporate customers with the excellent performance of the products, unique processing methods, or complete solutions. Mainly focusing on zirconia ceramic processing, the main products include: zirconia ceramic knives, zirconia ceramic ball valves, zirconia ceramic substrates, alumina ceramic sheets, zirconia ceramic tubes, alumina ceramic tubes, alumina ceramic sheets and other products.
1. Density comparison
The density of zirconia ceramics is twice that of alumina ceramics. In comparison, zirconia has better compression resistance.
2. Density comparison:
The density of zirconia ceramic structural parts is higher than that of alumina ceramics. The density of alumina ceramics is 3.5, while the density of zirconia ceramic structural parts is 6. The texture is finer. After grinding, the surface finish is higher, up to ▽ 9 or above, it is mirror-like, extremely smooth, and has a smaller friction coefficient.
3. Surface finish comparison:
The surface finish of the zirconia ceramic structural parts is higher, mirror-like, extremely smooth, and the friction with the mesh is smaller, which can further increase the service life of the mesh, greatly reduce the mesh consumption, reduce the current of the paper mesh, and reduce the power consumption. . In addition, the toughness of zirconia ceramic structural parts is extremely good, which overcomes the inherent brittleness of the ceramic itself, has higher wear resistance, greatly extends the service life of the product, and significantly improves the paper quality.
4. Comparison of ceramic toughness
The toughness of zirconia ceramics is 4 times that of alumina ceramics. At the same time, if the zirconia is dropped freely from a height of one meter, there will only be some gaps and the alumina will be broken.
5. Friction coefficient comparison:
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, more elastic and hard grinding amounts must be taken into consideration. The specific wear resistance of the material depends on the actual usage.
Zirconia ceramic structural parts are a newly developed structural ceramic that is very important after 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.
