Embodiment 1
[0033] A process for cleaning and defogging optical glass, comprising the steps of:
[0034] (1) Pre-cleaning, low-pressure flushing of the optical glass, and the flushing water is treated rinsing wastewater, and soaked for 10 minutes;
[0035] (2) Cleaning with cleaning agent, prepare and dilute the glass cleaning agent, spray the glass cleaning agent on the surface of the optical glass, clean it with a roller brush, and spray it repeatedly 3 times;
[0036] (3) Rinse, rinse the optical glass with clean water, the single rinse time is 8min, rinse twice, and collect and treat the wastewater after rinsing;
[0037] (4) To prepare the demisting water solution, first dissolve polyvinylpyrrolidone in deionized water, stir to dissolve, add ethylene glycol after it is fully dissolved, continue mixing and stirring for 1 hour, then precipitate for 24 hours, and filter the clear liquid to become the defogging water solution;
[0038] (5) Anti-fog treatment, put the optical glass into ...
