How many polishing methods are there for amino film?

There are many polishing methods for amino films, and the following methods are commonly used:

1. Mechanical polishing: The traditional polishing method is to use sandpaper or emery cloth with gradually decreasing roughness to achieve the purpose of polishing.

2. Chemical-mechanical polishing: using polishing solution with alumina as the main component, chemical reaction is carried out at the same time of mechanical polishing to achieve better polishing effect.

3. Electrochemical polishing: the oxidation-reduction reaction generated in the polishing process is controlled by parameters such as applied voltage and current to realize the polishing of the amino film.

4. Laser polishing: the amino film is processed by high-energy laser scanning to realize polishing.

The application of various polishing methods depends on the material properties, polishing requirements, polishing equipment, cost and other factors.
