Definitions

  • This invention relates to the production method of an antiglare glass on screens which are found at the front of electronical visual systems such as LCD, display, tablets, smart board and commercial type refrigerators.
  • the glass surface is loosed into a fluorosilicic super saturated acid (3 millimoles per litre) until the intended etch depth is obtained and thereby the skeletonizing treatment for the glass is performed.
  • the fluorosilicic acid solution of the solution used can be made by adding filtered, water diluted and precipitated silicic acid or hydrated silicic (and this provides a super saturated solution to be formed since the solubility of the silica increases and the density of the fluoride acid decreases).
  • the glass before starting the process, can be cleaned with hydrofluoric acid or with superheated, and condensed sodium hydroxide material.
  • the solution can be prepared by dissolving the glass containing silica, in fluorosilicic acid. Nonetheless, a certain amount of supersaturation can be applied only to a section of the glass and the saturation can be decreased by adding sodium and potassium fluoride or increased by adding H3Bo3i, NaOH, sodium silicate.
  • the thickness of the glass washed with a detergent and water mixture and then cleaned with ethanol can be etched in the range of 200 nm to 300 nm and antiglare peaks on the surface in the range of 10 to 160 nm can be formed (These treatments take 4 to 30 hours and the temperatures of the glass and the vapour are different).
  • using the glasses obtained by the applications mentioned in these documents do not give the intended results. For this reason, in order to eliminate the reflection on the screens of electronical video devices, the need for a novel glass production technique to be performed has risen. Purpose and Brief Description of the Invention
  • the purpose of this invention is to perform a production method of the glass to be used on the screens of electronic video devices, which will prevent reflection.
  • Another aim of this invention is to perform a production method of the glass, including the application of a solution to a surface of the glass comprising hydrofluoric acid, , barium sulphate and ammonium bifluoride, then removing the solution from the glass surface and immersing the glass again in a pool containing hydrofluoric acid.
  • the glass produced by acid etching technique can be cut into intended dimensions and then the glass will be taken through the entire treatment processes.
  • Detailed Description of the Invention The glass production method and line of production performed in order to accomplish the purposes of this invention are shown in the accompanying drawings. These drawings illustrate the following;
  • Figure-1 is the flowchart of the glass production method.
  • Figure-2 is the schematic view of the matting line at the production line where the glass production method takes place.
  • Figure-3 is the schematic view of the embossing line at the production line where the glass production method takes place.
  • the glass production method of the invention comprises the steps of
  • the first stage of the method takes place in the matting line (1).
  • the flat glass enters the matting line (1).
  • the glass is first washed by tap water in the washing unit (3) by means of lower and upper brushes.
  • the glass is washed again in the purified water washing unit (4) with purified water by being passed between the lower and upper brushes and the surface of the glass is cleaned and dried by being passed through drying fans (6).
  • the purpose here is to prevent the chemical from affecting the lower surface of the glass.
  • the solution comprising hydrofluoric acid, barium sulphate and ammonium bifluoride is drained onto the surface of the flat glass covered with foil by a curtain system (5) automatically.
  • the glass moving on the conveyors with the chemicals finishes its journey on time periods varying according to the haze degree of the desired product and the chemical is removed from the top of the glass by having the glass passed through the mains water washing unit (3) and the purified water washing unit (4) again.
  • the glass passing through the drying fans (6) is dried and then the protective foil on the back surface of the glass is removed.
  • the first step of the method is completed.
  • the products exiting the matting line (1) are controlled at the quality control unit (10) and are directed to the embossing line (2). These treatments are performed via the glass loading robot.
  • the second phase of the process takes place in the embossing line (2).
  • the non- matted surface of the semi-finished glass from the matting line (1) is covered with protective foil at the entrance of the embossing line (2).
  • the glass enters the decoration pool (7) filled with hydrofluoric solution and travels for approximately 36 m by being advanced on the rollers.
  • the speed at which this travel is desired again varies depending on the desired product qualities.
  • the glass is initially inserted into the prewashing machine (8).
  • the purpose here is to clean the glass from the acid remaining on its surface.
  • the glass is washed with mains water, by means of the lower and upper brushes and then dried via the drying fans (6).
  • the next stage is removing the protective foil from the glass and this treatment is performed by a semi-automatic machine.
  • the main washing machine (9) is used at the last stage.
  • the glass having been washed a few progressive times, is passed through the drying fans (6) and it reaches the quality control unit (10). As a result, the antiglare glass production is completed.
  • This glass can then be cut into intended dimensions according to the customer's demand and this process takes place in the cutting unit (11).
  • the glass can be subjected to all kinds of treatment processes.

Abstract

L'invention concerne le procédé de production d'un verre antireflet sur des écrans qui sont prévus à l'avant de systèmes d'affichage électroniques tels que des afficheurs à cristaux liquides, des afficheurs, des tablettes, des cartes à puce et des réfrigérateurs de type commercial. Selon l'invention, le procédé de production du verre consiste à : protéger la surface du verre qui ne sera pas matée de préférence en recouvrant avec une feuille ; appliquer une solution comprenant de l'acide fluorhydrique, du sulfate de baryum et du bifluorure d'ammonium à la surface du verre qui sera matée ; retirer la solution comprenant de l'acide fluorhydrique de la surface du verre ; sécher le verre après lavage ; recouvrir la surface du verre qui ne sera pas matée de préférence avec une feuille ; déposer le verre par immersion dans un bain contenant de l'acide fluorhydrique ; débarrasser le verre de l'acide fluorhydrique restant sur sa surface ; découper le verre aux dimensions souhaitées et soumettre le verre au processus de traitement.
