What are the polishing methods for zirconia ceramic materials?

Zirconia ceramics have high high-temperature structural strength and negative resistance temperature coefficient, so it is necessary to polish the material of the product under certain circumstances. The specific methods are as follows. Kezhong Ceramic Factory will briefly introduce to you:

1. Mechanical polishing: In order to improve work efficiency during large-scale construction of zirconia ceramics, mechanical polishing methods such as electric polishing machines (disc type, vibration type) can be used.

2. Dry polishing: Use sandpaper for polishing. Suitable for polishing hard and brittle paint, the disadvantage of polishing zirconia ceramic materials is that a lot of dust will be generated during the operation, which affects environmental hygiene.

3. Wet polishing: Use sandpaper dipped in water or soapy water to polish. Water grinding can reduce grinding marks, improve the smoothness of coatings, and save sandpaper and labor. However, attention should be paid to spraying the lower layer of paint after water grinding. Firstly, it is necessary to wait for the water grinding layer to completely dry before applying the lower layer of paint, otherwise the paint layer can easily turn white. Additionally, substrates with strong water absorption are not suitable for water grinding.

In order to ensure the better quality of zirconia ceramics, it is necessary to polish the materials during processing, so this work is very important.
