The ultra pure water equipment for optoelectronic optical glass is mainly used to provide water for ultrasonic cleaning during glass cleaning, ensuring that the water quality of the produced water is 18.2M Ω. cm, thereby meeting the demand for experimental water. This is because in the optoelectronic optical glass industry, ultrasonic cleaning of lenses is used to ensure the transparency of the lenses.

Grinding is an important process in the production of optical glass that determines its processing efficiency and surface quality (appearance and accuracy). The main pollutants in the grinding process are grinding powder and asphalt. In some enterprises, there may be paint flakes during the processing. The types of grinding powder are different, usually alkali metal oxides mainly composed of cerium dioxide. Different types of grinding powder are selected according to the material and grinding accuracy of the lenses. The asphalt used in the grinding process is protective to prevent scratches or corrosion on the polished mirror surface. After glass grinding, it is necessary to clean the product with ultrapure water to obtain high-quality products.

However, the source water contains a large amount of suspended solids, particulate matter, and ionic substances, which can cause pollution and scratches on the lenses during ultrasonic cleaning, resulting in insufficient clarity of the lenses. The ultra pure water equipment provided by the infiltration source to the ultrasound adopts a two-stage reverse osmosis+EDI process, which can effectively remove particulate matter and pollutants from the raw water, ensuring that the final effluent quality can reach 18.2M Ω. cm. The equipment adopts PLC+intelligent touch screen control, and fully automated treatment can ensure the stability of the system.
