Abstract

PURPOSE: A glass chamfering method through hydrofluoric acid is provided to effectively and partially cut chamfer part of the glass by using a chemical which can melt the glass. CONSTITUTION: A glass chamfering method through hydrofluoric acid comprises the following steps: covering wax on whole surface of the first external angle processed glass; cleaning wax of the chamfering part with an elastomer pad or a cloth; automatically processing grinding operation by reacting the glass with hydrofluoric acid and melting only the chamfer part. The wax does not react with the hydrofluoric acid. The glass and hydrofluoric acid reaction step comprises the following step; dipping the glass into the fluoric acid solution, or spraying the fluoric acid solution with a spray nozzle.

Glass chamfering method through Foshan {glass}

lcd유리,평판디스플레이유리,이동단말기 윈도우lcd glass, flat panel display glass, mobile terminal window

현재 평판디스플레이,이동단말기등의 윈도우 소재가 아크릴계통에서 유리로 전이되는단계로서 아크릴은 cnc등으로 쉽게가공되었으나 유리는 다이야몬드휠을사용하여 가공하기때문에 가공이 힘들고 다이야몬드입자의 비산등에 의해 유리표면에 흠집이생겨 불량률이 높고 생산원가가 많이드는등의 문제가 있다Currently, window materials such as flat panel displays and mobile terminals are transferred from acrylic system to glass.Acrylic is easily processed by cnc, but glass is difficult to process because it is processed using diamond wheel, and glass is scattered due to scattering of diamond particles. There are problems such as scratches on the surface, high defect rate and high production cost.

유리가공 공정중 테두리 모서리 부분의 모따기 공정을 다이야몬드 휠로 가공하다보니 다이야몬드 입자에의한 흠집 불량이 많이 나오고 1개씩 가공하다보니 가공비가 많이 드는단점을 보완하기위하여 유리를 녹일수있는 화학약품을 사용하여 모따기부분을 녹이는 방법으로 면취를 하고자한다.As the chamfering process of the edges of the edges of the glass processing process is done with diamond wheels, there are many scratch defects caused by diamond particles and each one is processed so that the chemicals that can melt glass to compensate for the disadvantages of high processing cost I want to chamfer it by melting the chamfer.

면취하고자하는 외각가공한 유리 전체 표면에 왁스를 입힌후 면취하려고하는 모서리부분만 왁스를 고무패드나 천등으로 왁스를 닦아낸후 불산용액에 넣어 불산이 유리표면과 접촉되는 모서리부분만 녹여 면취하고자한다
Wax the entire surface of the outer surface of chamfered glass to be chamfered and wipe the wax only with the rubber pad or cloth, and then put it in hydrofluoric acid solution and dissolve only the edge where the hydrofluoric acid is in contact with the glass surface.

불량률이없이 대량생산 용이하다Easy to mass production without defective rate

1차로 외각가공공정을 거친 유리 전체 표면에 불산에 반응하지않는 왁스를 입힌후 면취하려고하는 모서리부분만 왁스를 고무패드나 천등으로 왁스를 닦아낸후 불산용액에 넣거나 불산용액을 스프레이 노즐등을 통해 분사하게되면 불산이 묻어있지않은 유리표면과 접촉되는 모서리부분만 불산과 유리가 반응하여 자동적으로 면취가 된다Apply wax that does not react with hydrofluoric acid to the entire surface of the glass that has been subjected to the external processing first, and then wipe the wax with a rubber pad or cloth, and then insert the wax into hydrofluoric acid solution or spray the hydrofluoric acid solution through a spray nozzle. In this case, the hydrofluoric acid and the glass react automatically to chamfer only at the edges in contact with the glass surface which does not have any hydrofluoric acid.

Claims

In the chamfering process of glass processing
Apply wax that does not react with hydrofluoric acid to the entire surface of the glass that has been subjected to the external processing first, and then wipe the wax with a rubber pad or cloth, and then insert the wax into hydrofluoric acid solution or spray the hydrofluoric acid solution through a spray nozzle. This method is to chamfer the glass edges through Foshan, where the hydrofluoric acid and glass react automatically when only the edges that come into contact with the glass surface that are not buried are automatically chamfered.
