Treatment method of glass metal in platinum channel

Abstract

The invention relates to a treatment method of a glass metal in a platinum channel for reaching satisfactory clarification effect hardly reached by a common clarifying process. The treatment method of the glass metal in the platinum channel solves the problems of low quality and low efficiency of a process which requires a clarification temperature over 1600 DEG C. The invention fully integrates a clarifying process, a homogenating process, a homogenizing process and a power supply process to carry out in the platinum channel. According to different functions and conditions of different parts, the platinum thickness is 0.8-3 mm, the special stability of platinum is utilized to realize high-temperature clarification which can realize the high-quality glass metal hardly obtained by a common tank furnace, and the classified glass metal is basically in a full-closed state without external pollution or glass component volatilization so as to ensure the evenness of the glass metal components and realize the full evenness of the glass metal component by stirring in match. Fireproof insulated materials of different thicknesses are arranged at the outer side of the platinum according to different aims of different sections.

Description

technical field [0001] The invention provides a platinum channel used for the production of liquid crystal glass substrates, in particular, it is suitable for the method for processing glass liquid in the platinum channel. Background technique [0002] The melting and refining of glass is a very complicated process, which includes a series of physical changes and chemical reactions. During the glass melting process, there will be many defects, such as bubbles, stones, streaks, etc. Among them, the bubbles and streaks are the main ones, which need to be eliminated during the clarification process. [0003] The clarification of glass is generally divided into two stages, one is the high-temperature defoaming stage, and the other is the low-temperature absorption stage. The high-temperature stage is the process of large bubbles escaping, while the low-temperature stage is the process of small bubble absorption. When the temperature of the molten glass is raised to a certain te...

Problems solved by technology

In this case, due to the incomplete separation of melting and high-temperature clarification, the unmelted molten glass may enter the clarification circulation under certain process conditions or under the influence of external conditions, resulting in poor clarification and cannot be fully controlled.

And there is only a short distance from the flow hole, even if a large number of cold air and cold water pipes are added outside the insulation brick, the effect is still unsatisfactory, and the erosion of the refractory material here is very serious

Not only affects the service life of the pool furnace, but also increases the chance of glass defects
