Filling slurry for glass substrate and its preparation method and mixing device

Abstract

The invention relates to a filling slurry for a glass substrate, a preparation method thereof and a mixing device, wherein the slurry comprises 75-80% of alumina, 8-10% of water, 4-6% of polyacrylic acid ammonia, and carboxymethyl Cellulose 9-10%; when preparing, adjust the pH value of the water to 10-11 with ammonia water, then add alumina, polyacrylic acid ammonia and carboxymethyl cellulose in sequence, and stir for 24-30 hours to obtain; active in the mixing device The position setting of the roller shaft and the driving roller, the driven roller shaft and the driven roller, and the radius of the driving roller shaft and the driven roller shaft are the same, and the radius of the driving roller and the driven roller is the same. Under the action of the limit device, the driving roller The shaft and the driven roller shaft are set in parallel and have the same height, which can ensure that under the action of the motor, the first conveyor belt and the second conveyor belt, the driving roller shaft can drive the driven roller shaft to rotate, and the material barrel and the driving roller shaft can be connected by inherent friction. The rollers and driven rollers rotate synchronously to meet the time requirement of 24-30 hours for mixing materials.

Description

technical field [0001] The invention relates to the field of production of liquid crystal glass substrates, in particular to a glass substrate filling slurry, a preparation method and a mixing device thereof. Background technique [0002] The platinum channel is a crucial part in the production of liquid crystal glass substrates for TFT-LCD. Its main function is to clarify, homogenize and adjust the viscosity of the molten glass, improve the defects of the molten glass, and provide qualified and high-quality molten glass for the next process. [0003] During the installation process of the cooling section of the platinum channel with a length of 3.46m, there is inevitably a gap of 8-10mm between the peripheral alumina heating wire brick. Oxidation, on the other hand, affects the overall strength of the cooling section of the channel. Therefore, a ceramic slurry with the same composition as the heating wire brick is prepared and poured in the gap between the cooling section a...

[0003] During the installation process of the cooling section of the platinum channel with a length of 3.46m, there is inevitably a gap of 8-10mm between the peripheral alumina heating wire brick. Oxidation, on the other hand, affects the overall strength of the cooling section of the channel. Therefore, a ceramic slurry with the same composition as the heating wire brick is prepared and poured in the gap between the cooling section and the heating wire brick. After sintering at high temperature, it is combined with the heating wire brick and platinum. The integration of the cooling section of the channel is the key to solve this problem, but there is no such slurry in the prior art
