In optical processing companies, there are many common problems in optical glass lens cleaning, but the more common problems are white spots and watermarks. The following analysis describes:
Â
1. White glass after tempering:
After tempering, white spots and watermarks appear on the white glass. First, we must test whether the quality of the pure water is up to standard, and then see if the optical glass cleaning agent has been used for a long time, the water temperature of the cleaning tank is up to standard, and the fan filter in the oven is It is not too long and dirty; there is also the ability to check whether the vibration of the ultrasonic wave is too small or unstable, the pure water tank is to update the pure water regularly, and so on, and certain operational problems.

If white spots or watermarks appear as well, refer to the inspection method of the above 1 for analysis. There are also many factors that affect the silk screen to remove the silver surface. First, we must consider whether the pH value of the cleaning agent is too high, whether the ultrasonic wave is too strong, and whether the cleaning water temperature is too high.
