Optical systemIn each processing process of glass, cleaning treatment is usually needed due to the conditions of surface dust, grease, white spots and the like. And the optical glass with high abrasion and low chemical stability refers to the condition that any one of the following conditions is satisfied: 1. the abrasion degree is high: relative grinding hardness FA FANot less than 300, relative grinding hardness FAThe abrasion resistance is a numerical value obtained by multiplying the ratio of the abrasion loss of a sample to the abrasion loss (volume) of standard sample K9 glass by 100 under the same conditions, wherein the higher the value is, the worse the abrasion resistance is; 2. the chemical stability is low: stability to Water action DWNot less than 4, stability against acid action DANot less than 4, stability against water action DWAnd stability against acid action DAThe higher the values of both, the worse the environmental resistance.
The cleaning difficulty of the glass with high abrasion degree and low chemical stability is relatively high, the cleaning mode of the product at present mainly depends on ether and ethanol for manual wiping treatment, and the treatment method has the following problems:
1. the efficiency is low, and if the appearance of a common soft material product meets the coating requirement, a skilled worker can only wipe about 1 sheet per minute;
2. the cost is high, and because the wiping efficiency is low, more personnel are needed for corresponding production, so that the labor cost is high;
3. the quality of the treated product is poor, and bright wires, scars and wiping marks are more in the manual wiping process, so that the qualified rate is low, the appearance requirement of a coating film cannot be met, and the cleaning yield is less than 50%;
disclosure of Invention
The invention aims to solve the technical problem of providing a method for cleaning high-abrasion-degree low-chemical-stability optical glass, which has high efficiency, lower cost and better quality of a treated product.

Through the quality control of supplied materials, products before cleaning are free from intractable objects such as grinding powder and fingerprints.
The solvent cleaning is to use the prepared weak alkaline solvent to clean for 2min +/-30S in an ultrasonic groove of 120-170KHZ and 900W at the temperature of 40 +/-5 ℃.
The tap water rinsing refers to that disposable tap water overflows to clean for 2min +/-30S in a 120-DEG 170KHZ 900W tap water ultrasonic cleaning tank.
The pure water cleaning adopts two tanks of pure water cleaning, each tank of pure water uses one-time overflow, the ultrasonic wave of the pure water in each tank is 120-170KHZ and 900W, and the cleaning time is 2min +/-30S respectively.
The isopropanol cleaning adopts two-groove isopropanol cleaning, the ultrasonic wave of each groove is 120-170KHZ and 900W, the cleaning time is 2min +/-30S respectively, and the density is controlled to be less than 0.820g/cm 3.
