Wash and clean with organic solvent, the process is as following:
Organic solvent cleaner (ultrasonic) - water-based cleaner (ultrasonic) - municipal water rinse - pure water rinse - IPA (isopropanol) dehydration - IPA pull drying slowly.
The main use of organic solvent cleaners is to clean asphalt and lacquer. The primary use of water-based cleaners is to clean abrasive powders. Since the abrasive powder is an alkali metal oxide, the solvent has a weak cleaning ability, so the abrasive powder generated during the processing of the lens is basically removed in the water-based cleaning unit, so that the water-based cleaning agent is highly demanded.
In the past, due to the small variety of water-based cleaning agents for Optical Glass in China, many foreign-funded enterprises have used imported cleaning agents. At present, domestic companies have developed Optical Glass cleaning agents, and have successfully applied them to several large Transparent Optical Glass production plants in China. The cleaning effect can completely replace imported products, and it is superior to imported in terms of corrosive (anti-corrosion performance) and other indicators. product. For IPA slow-drawing drying, it should be noted that some types of lenses are prone to watermarking after drying. This phenomenon is related to the purity of IPA and air humidity on the one hand, and has a great relationship with cleaning equipment on the other hand, Especially The effect of drying the arms is obviously not as good as that of the one-arm drying. It is necessary for equipment manufacturers and users to pay attention to this point.
