AI Technical Summary

Benefits of technology

This patented technology helps prevent damage caused by depositing unwanted materials onto surfaces during manufacturing processes like lamination or co-firing. It achieves this through an effective removal agent that does away quickly but doesn't harm any other parts of the product being made from it. Additionally, its composition makes it easy to prepare without causing problems when used properly. Overall, these technical benefits make the production more efficient while maintaining quality control standards.

Problems solved by technology

The technical problem addressed by this patented technology relates to finding ways to efficiently clean optically transparent coatings during manufacturing processes while maintaining their desired qualities like strength, durability, etc., which may result in wasted product that needs remanufacture or repainting.

Embodiment 1

[0049] A kind of deplating solution of silicon oxide / silicon nitride film on glass surface is made up of following components by weight: potassium hydroxide 15%, diglycolamine 4%, anhydrous sodium metasilicate 6%, Disodium edetate 3%, alkyl glycoside APG 2%, the balance is water.

[0050]Fully immerse the touch screen glass coated with silicon oxide / silicon nitride in the above deplating solution, soak for 45 minutes at about 90°C, take it out, rinse it with water, and check that the film layer can be completely removed. There is slight corrosion on the glass surface, which needs to be polished in the next process.

Embodiment 2

[0052] A kind of deplating solution of silicon oxide / silicon nitride film on the surface of glass, consisting of the following components by weight: 10% sodium hydroxide, 8% triisopropanolamine, 3% sodium citrate, 5% borax %, tetrasodium edetate 2%, isooctyl ether phosphate 5%, and the balance is water.

[0053] Fully immerse the touch screen glass coated with silicon oxide / silicon nitride in the above deplating solution, soak for 60 minutes at 85°C, take it out, rinse it with water, and check that the film can be removed. The surface of the glass is slightly corroded, and it can be circulated according to the normal process after polishing.

Embodiment 3

[0055] A kind of deplating solution of silicon oxide / silicon nitride film on glass surface is made up of following components by weight: potassium hydroxide 5%, triethanolamine 8%, sodium silicate 3%, sodium tartrate 5%, Alkyl glucoside 2%, sodium dodecylbenzene sulfonate 2%, the balance is water.

[0056] Completely immerse the touch screen glass coated with silicon oxide / silicon nitride in the above stripping solution, soak for 30 minutes at 95°C, take it out, rinse it with water, and check that the film can be removed. The surface of the glass is slightly corroded, and it can be circulated according to the normal process after polishing.

Abstract

The invention provides a deplating liquid for a glass surface membrane and a use method and application of the deplating liquid. The deplating liquid comprises the following components in percentage by mass: 5-30% of an inorganic alkali, 3-20% of an organic alkali, 2-10% of a corrosion inhibitor, 2-15% of a chelating agent, 1-5% of a surfactant and the balance of pure water. The invention furtherprovides a method for deplating with the deplating liquid. The method comprises the following steps: soaking glass to be deplated with the deplating liquid, and fishing out 30-60 minutes later. The invention further provides application of the deplating liquid to glass that a silicon oxide or silicon nitride membrane layer is arranged on a deplating surface, preferably, the glass is a mobile phoneglass panel or window glass of a tablet personal computer.
