Problems solved by technology

Therefore, the judgment of the quality of optical glass also includes some special and strict indicators. Optical glass must first have a high degree of transparency, so the cleaning and defogging of optical glass become particularly important and difficult, but In the prior art, there is no very good process flow that combines cleaning and demisting processes

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 ...

Abstract

The invention discloses an optical glass cleaning and demisting method. The optical glass cleaning and demisting method comprises following steps: 1, precleaning; 2, cleaning with a cleaning agent; 3, rinsing; 4, preparing of a demisting aqueous solution; 5, anti-mist treatment; and 6, air drying. Optical glass are subjected to cleaning and demisting via the above six steps, after cleaning, no residue or particle matter is left on the surfaces of lens; clean class is high; cleaning and demisting are combined, so that steps are avoided, fewer steps are needed, and technology is simplified, subsequent processing of optical glass is not influenced; practicability is high; and waste water generated in step 3 is recycled, is treated, and then is used for precleaning in step 1, so that water is recycled, and water resource is saved.

Description

technical field [0001] The invention relates to the technical field of glass cleaning treatment, in particular to an optical glass cleaning and defogging process. Background technique [0002] Optical glass is the foundation and an important part of the optoelectronic technology industry. Especially after the 1990s, with the continuous integration of optics, electronic information science, and new material science, the application of optical glass as the basic material of optoelectronics in the three major fields of optical transmission, optical storage, and optoelectronic display has advanced by leaps and bounds. It is one of the basic conditions for the development of social informatization, especially photoelectric information technology. The difference between optical glass and other glasses is that it, as a part of the optical system, must meet the requirements of optical imaging. Therefore, the judgment of the quality of optical glass also includes some special and st...
