1. Granularity range
The particle size range of ceramic structured packing should meet the relevant technical requirements to ensure the filling effect and performance of the packing. In general, the particle size range of the filler should be between 50 mesh and 300 mesh, of which 50 days to 100 mesh filler should account for more than 70% of the total. In addition, the particle size distribution of the packing should be as uniform as possible to ensure the filling effect and performance of the packing.

Second, shape requirements
The shape of ceramic structured packing shall meet the following requirements:
1. The particle shape should be as regular as possible to ensure the filling effect and performance of the filler.
2. The particle surface should be smooth and clean, without defects and impurities.
3. The length and width of the particles should be appropriate to ensure the filling effect and performance of the filler
3. Physical performance requirements
Ceramic structured packing should have good physical properties, including:
1.Specific gravity: the proportion of the filler should be moderate to ensure the filling effect and performance of the filler.
2. Hardness: the hardness of the filler should be moderate to ensure that the filler is not easy to break during use.
3. Wear resistance: the wear resistance of the packing should be good to ensure that the packing is not easy to wear during use
4. Corrosion resistance: the filler should have a certain corrosion resistance to ensure that the filler is not easy to be corroded during use.
4. Chemical performance requirements
Ceramic structured fillers should have good chemical properties, including:
1. Chemical stability: the chemical stability of the filler should be good to ensure that the filler is not easy to chemical reaction during use. 2. High temperature resistance: the filler should have a certain high temperature resistance to ensure that the filler is not easy to deformation or damage during use,3. Corrosion resistance: the filler should have a certain corrosion resistance to ensure that the filler is not easy to be corroded during use.
