Embodiment Construction

[0013] Embodiment, the cutting method of flat toughened glass, comprises the following steps in sequence:

[0014] 1) Print acid-resistant ink on the left and right sides of the flat tempered glass to be cut by screen printing and let it dry. Wherein, the acid-resistant ink adopts commercially available common acid-resistant ink. After printing ink, it is best to place it horizontally to dry, and print on the other side after drying on one side.

[0015] 2) Use a pointed knife to draw double-sided ink on the part of the flat tempered glass to be cut after the treatment in step 1), so that the ink on the part to be cut is removed and the glass is exposed. Among them, the hob can be used as the pointed tool, and the width of the drawn line should preferably not exceed 0.8mm. At the same time, the so-called double-sided depiction refers to the fact that the lines formed on both sides of the flat tempered glass are completely overlapped after the factor of glass thickness is rem...

Abstract

The invention discloses a method for cutting flat tempered glass. The method sequentially comprises the following steps: printing oilproof ink on the left and right side faces of flat tempered glass to be cut in a silk screen printing manner, and air drying the ink; engraving double surfaces of the ink on a position to be cut of the flat tempered glass by using a pointed tool to remove the ink on the position to be cut and expose the glass; vertically putting the flat tempered glass in a mixed solution containing hydrofluoric acid, hydrochloric acid and nitric acid, taking out the flat tempered glass after every 5-10 minutes, flushing glass fragments on the position to be cut by using a water gun, and then putting the flat tempered glass in the mixed solution until the flat tempered glass is cut; soaking the cut flat tempered glass in an alkaline solution until the oilproof ink is removed, then cleaning the flat tempered glass with clear water, and air drying the flat tempered glass; edging the flat tempered glass by using an edging machine. The method disclosed by the invention has the advantages of being relatively simple and smaller in equipment investment.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a cutting method of flat toughened glass. Background technique [0002] Tempered glass has an extremely wide range of applications. Usually, in order to meet the needs of use, tempered glass is often processed by cutting, edging, etc. before tempering. However, in some special cases, if the glass is cut first and then tempered, the lack of precision of the glass is prone to occur. For this reason, it is necessary to cut the tempered glass. At present, the cutting of commonly used toughened glass is mostly done by laser. Such a method requires a large investment in equipment. Contents of the invention [0003] The purpose of the present invention is to provide a cutting method of flat toughened glass, which is relatively simple and has the characteristics of less investment in equipment. [0004] The technical scheme adopted in the present invention is: the cutting...
