A superficial treatment system for glass mainly comprises a storage tank for soaking glass, a chemical solution releaser for releasing a chemical solution to the storage tank. When the chemical solution of the chemical solution releaser overflows naturally, the chemical solution flows into the storage tank and is excluded from a drain valve so as to use the chemical properties of the chemical solution to treat optical glass immerged in the storage tank, but resultant is not remained in the storage tank.
Description
Technical field
The invention relates to a kind of surface treatment method, especially for the superficial treatment system of glass.
Background technology
Under the trend of liquid-crystal display lightweight, slimming and wide viewing angle, high brightness, liquid crystal manufacturers proposes the thin type means at different spare parts one after another, particularly takies the bigger glass substrate of volume, especially the main thin type means that adopt of manufacturers.
For the thinning glass substrate, existing manufacturer proposes the whole bag of tricks one after another, and these methods roughly are divided into Dip (immersion of multi-disc vertical type), In-line horizontal (sprinkling of monolithic level), Spray (sprinkling of monolithic vertical type).No matter which kind of method mainly all waits the tropism to handle with chemical solution (for example hydrogen fluoride solution) to glass substrate, utilize control device such as treatment time to come thinning glass substrate gradually, cooperate the further thinning glass substrate of physical treatment again.Adopt above technology, the thickness of glass substrate develops into present 0.1mm from the 1.2mm of nineteen ninety-five.Yet the defective of above-mentioned means itself has caused producing other problems in the thinning process.
