Problems solved by technology

[0002] In the traditional glass preparation method, the glass raw material is melted in a platinum crucible, and then the molten glass is poured into a rectangular open mold composed of steel plates and steel bars by manually clamping the crucible. The temperature changes rapidly, resulting in wavy or group-like streaks inside the formed glass block, resulting in serious unevenness of the glass body, which affects the mechanical and optical properties of the glass in the process of glass performance testing, especially when the surface of the cover glass is chemically tempered. When stress occurs, the image is blurred and the stress stripe image cannot be found, which seriously affects the accuracy and reliability of the test results

Embodiment 1

[0031] After weighing according to the cover glass formula, pour the glass material into a plastic ziplock bag, seal the ziplock bag with a certain amount of air, roll up the mouth of the bag to form a sealed space, hold the ziplock bag with both hands, and mix it by shaking. Minutes to get a uniform mixed material. A rectangular corundum tank with a wall thickness of 4mm and a length*width*height of 80mm*65mm*90mm is placed on a refractory tray and placed in a muffle furnace to preheat to 800℃. The material of the corundum tank is white corundum. Then, the mixed materials are slowly added to the preheated corundum tank placed on the refractory tray, and then the tray and the filled corundum tank are placed in the set operating curve high-temperature sample melting furnace for melting treatment and melting treatment The temperature is 1580°C and the time is 7.5h. A platinum stirring rod is used to stir and homogenize the molten glass 2 hours before the completion of the melting...

[0033] After weighing according to the TFT-LCD glass formula, pour the glass material into the plastic ziplock bag, seal the ziplock bag with a certain amount of air, roll up the mouth of the bag to form a sealed space, hold the ziplock bag with both hands, and mix it by shaking. A uniform mixed material is obtained in 4 minutes. A rectangular corundum tank with a wall thickness of 6mm and a length*width*height of 100mm*90mm*100mm is placed on a refractory tray and placed in a muffle furnace to be preheated to 700℃. The material of the corundum tank is zirconium corundum. Then, the mixed materials are slowly added to the preheated corundum tank placed on the refractory tray, and then the tray and the filled corundum tank are placed in the set operating curve high-temperature sample melting furnace for melting treatment and melting treatment The temperature is 1600°C, and the time is 7.5h. The platinum stirring rod is used to stir and homogenize the molten glass 3 hours before t...

Abstract

The disclosure discloses a method for preparing a glass test sample. The method comprises the following steps: a. uniformly mixing glass raw materials according to the formula to obtain a mixed material; b. placing the mixed material in step a Carry out melting treatment in the corundum tank; c, cooling and annealing after the melting treatment is completed, to obtain a glass test sample that is integrated with the corundum tank; d, cutting off the corundum tank part of the glass test sample obtained in step c . The test results of the glass test sample prepared by the method are accurate and reliable when the mechanical and optical tests are carried out.

Description

Technical field [0001] The present disclosure relates to the field of glass manufacturing and processing, and in particular, to a method for preparing glass test samples. Background technique [0002] In the traditional glass preparation method, the glass raw materials are melted in a platinum crucible, and then the molten glass is poured into a rectangular open mold composed of steel plates and steel bars by manually clamping the crucible. The temperature changes rapidly, causing waves or clusters of stripes in the formed glass block, causing serious unevenness in the glass body, which affects the mechanical and optical performance testing of the glass during the glass performance testing process, especially the surface of the cover glass after chemical tempering During stress, the image is blurred and the stress fringe image cannot be found, which seriously affects the accuracy and reliability of the test results. Summary of the invention [0003] The purpose of the present dis...
