Abstract

The invention relates to the technical field of glass cover processing, in particular to the application of a UV protective oil to solve the warping of float glass. The UV protective oil is rolled on the tin surface of the float glass, and the air surface of the float glass is used to sweep For light treatment, the present invention roll-coats the UV protective oil on the tin surface of the float glass, and the air surface of the float glass is used for light-sweeping treatment, that is, the air surface is swept on one side, and at the same time, the air surface is "micro-swept" by the light-sweeping medium. "Damage" reduces the Na+ content on the air surface and affects the exchange of potassium and sodium on the air surface, which is just consistent with the surface stress on the tin surface, reduces the warpage of the glass after chemical tempering, improves the flatness of the glass, and lowers the processing cost.

Description

technical field [0001] The invention relates to the technical field of glass cover plate processing, in particular to the application of a UV protective oil in solving the warping of float glass. Background technique [0002] Float glass is currently the most widely used production method for flat glass. The glass produced by it has the advantages of no ribs, good flatness, uniform thickness, compact structure, and smooth hand feeling. Currently, the surface protection of touch devices such as mobile phones and computers Float glass is generally used for the cover plate. At present, the process of processing the float glass protective cover includes the steps of raw glass, surface treatment, cutting, milling shape, cleaning and chemical toughening. , because the content of sodium ions on the tin surface is relatively reduced, which affects ion exchange, but the ion exchange on the air surface is not affected, so the ion exchange capacity on both sides of the glass is differ...
