A glass cutting edge coating process

Abstract

The invention provides a cutting edge coating process of glass, comprising the following steps: cutting ordinary glass with a glass cutting machine according to the size requirements to obtain a substrate; roughly grinding the four cutting edges of the substrate; polish the sides; use a high-pressure water gun to wash the four cutting edges of the substrate; clean the substrate with clean water, and cover a self-adhesive protective film on the front and back of the substrate after drying; Coat the mixture of titanium powder, foaming agent, carrier resin, and glass glue, and then place it in a high-vacuum sintering furnace for sintering for 2 to 3 hours. A layer of foamed titanium film will be formed on the four cutting edges of the substrate; after cooling, the The self-adhesive protective film on the front and back of the substrate is removed. In the glass cutting edge coating process of the present invention, a layer of foamed titanium film is formed on the surface of the cutting edge, which enhances the stability of the glass and improves the acid and alkali corrosion resistance, oxidation resistance and antimicrobial performance of the glass.

Description

technical field [0001] The invention relates to the field of glass processing, in particular to a glass cutting edge coating process. Background technique [0002] Glass is an amorphous inorganic non-metallic material, generally made of various inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) of. Its main components are silicon dioxide and other oxides. The chemical composition of ordinary glass is Na 2 SiO 3 , CaSiO 3 , SiO 2 or Na 2 O CaO 6SiO 2 etc., the main component is silicate double salt, which is an amorphous solid with irregular structure. [0003] Glass is widely used in the field of doors and windows. The general glass processing techniques include cutting, grinding, cleaning, drying, and framing. After the glass is cut, there will be fine cracks on the cutting surface, which cannot be eliminated by grinding. Long-term use will have a great impact on the stability of the glass. In...

Problems solved by technology

After the glass is cut, there will be fine cracks on the cutting surface, which cannot be eliminated by grinding.

Long-term use will have a great impact on the stability of the glass. In the field of doors and windows, an aluminum alloy frame is generally added to the four edges of the glass. Since the aluminum alloy frame is a hard material, if there is a crack on the cutting edge of the glass , the aluminum alloy frame exerts pressure on the cutting edge of the glass, which further increases the crack and eventually leads to the breakage of the glass

On the other hand, due to the roughness of the glass cutting surface, the internal structure of the glass is not protected, resulting in poor acid and alkali corrosion resistance, oxidation resistance, and anti-microbial performance of the glass.
