Due to the fact that grinding powder is an alkali metal oxide, solvents have weak cleaning ability for it. Therefore, the grinding powder generated during lens processing is basically removed in water-based cleaning units, which places extremely high demands on water-based cleaning agents. Previously, due to the limited variety of water-based cleaning agents for optical glass in China, many foreign-funded enterprises chose imported cleaning agents. At present, domestic companies have developed optical glass cleaning agents and successfully applied them in several large optical glass production plants in China. The cleaning effect can completely replace imported products, and it is even better than imported products in terms of corrosiveness (anti-corrosion performance) and other indicators.
