As a high-precision industrial material, the smoothness of the dehydration component ceramic plate has an important impact on its performance and service life. Generally speaking, finish refers to the smoothness of a material's surface. In membrane filtration, ceramic plates with higher smoothness will make the filtration effect more excellent.
According to the national standard "Measurement of Solid Surface Finish" (GB/T 15601-1995), the finish is divided into the following levels:
1. Very smooth: no defects can be detected and the gloss is extremely high.
2. Smooth: Very subtle defects can be detected, and the gloss is still very high.
3. Slight scratches: Fine scratches or small bumps can be seen, and the gloss is slightly reduced.
4. There are scratches: there are many large defects or bumps on the surface, and the gloss is significantly reduced.
5. Rough: The surface is rough and uneven, with low gloss.
In practical applications, different industrial production environments will have different requirements for the smoothness of ceramic plates. Therefore, during the production process, different grades of ceramic plates need to be selected according to specific needs, and their production processes and testing methods need to be reasonably controlled.
