Glass polishing refers to the use of chemical or physical methods to remove grain, scratches and other defects on the surface of glass, improve the transparency and refractive index of glass, and make glass more vitrified.
1. Fire Polishing
By softening the glass surface by flame and impacting the glass by fire, some grain patterns on the surface of glass products can be solved, but the smoothness of the glass surface after treatment will be reduced. Generally, the mouth of hollow vessels after glass cutting is rough and can be polished by this method.
Applicable Material Glass: Sodium Calcium Glass, High Borosilicate Glass
Negative effects: explosive
2. Polishing Powder Polishing
The use of polishing powder to remove scratches, sassafras, etc. on the surface of glass can maximize the transparency and refractive effect of glass!!!! Before polishing, the polished part should be polished with abrasive belt, and the pure surface should be polished with more than 400 meshes of diamond grinding disc. This polishing method has many tools and materials, but it is effective. The best result is wool wheel + cerium oxide (commonly known as rare earth polishing powder).
Applicable Material Glass: Most Glass Products
Negative effects: slower
3. Acid Polishing
Surface treatment of glass using acid to corrode glass also requires abrasive belt polishing before polishing, because acid polishing can reduce the thickness of glass a lot, but not necessarily remove all the grain of glass. Its formula varies according to the material of glass. This method is dangerous. Great! Non-professionals and companies with complete equipment do not recommend personal testing.
Applicable Material Glass: Any glass (but the effect of polishing depends on the material itself)
Negative effect: the smoothness is not well controlled, and the diamond angle of glass products has a certain loss.
