Zusammenfassung: | The invention discloses a high-abrasion-degree low chemical stability optical glass cleaning method. The high-abrasion-degree low chemical stability optical glass cleaning method is characterized by comprising the steps of solvent cleaning, tap water rinsing, pure water cleaning, isopropyl alcohol cleaning and isopropyl alcohol drying. A solvent is composed of the following substances including, by mass, 0.1%-0.5% of sodium hydroxide, 0.1%-0.5% of isopropanolamine, 1%-3% of sodium carbonate, 5%-10% of sodium phosphate and the balance water, and the pH of the solvent after blending is 8-9. Theadvantages are that a high-frequency ultrasonic matched high-activity low-concentration weak alkaline solvent cleaning process is used for replacing a manual wiping process, and dirty such as dust, grease and white spots on the surface of a product can be effectively removed on the basis that no undesirable products are generated; the efficiency is improved, the soft material cleaning frequency is2 min per basket, 40 piec |
