Principle of glass correction:
Grind and then polish. The detailed description is: for more serious scratches, first use a relatively large particle size (35μ) polishing pad to grind the scratches off, and then use fine polishing pads (20μ, 10μ, 5μ) for fine grinding in turn, and finally Use pure wool polishing disc and polishing paste for polishing. After polishing the correction area, the glass scratch correction is over. Although partial and small-scale scratch correction can save cost and time, the effect of correction is not good; if the corrected area is expanded, a good correction effect will be obtained, but it will also increase the cost and time of correction. So choose the appropriate correction method according to the actual situation.
Scratch correction steps:
1. Determine the location of the scratch:
The first step in correcting scratches is to determine the location of the scratches. Use enough water and paper towels to thoroughly clean the surface of the entire glass, and it is best to mark the back of the glass to make it easier to correct.
2. The standard for judging the degree of glass scratches and the combination of polishing sheet correction:
If there are deep scratches on the glass: scratches that can be seen directly and can be felt with fingers. Modification combination: you can use green, pink, blue, and orange polishing pads in order to polish, and finally polish.
Moderate scratches: scratches can be seen directly, but not felt by fingers, only scratches can be felt with fingers. Modification combination: You can use pink, blue, and orange polishing pads to grind in sequence, and finally polish.
Minor scratches: scratches can be seen directly, but not felt by the fingernails. Modification combination: The blue and orange polishing pads can be used in turn for grinding and final polishing.
3. Mao Dao: scratches that can only be seen at a special angle but cannot be touched by hand. Modification combination: Use orange polishing pads to grind, then polish or directly polish.
