Double platinum channel structure for ultrathin glass substrate

Abstract

The invention belongs to the technical field of display glass production equipment and particularly relates to a double platinum channel structure for an ultrathin glass substrate. For the double platinum channel structure, by utilizing a platinum channel in the prior art, a platinum channel main body is divided into an inlet connection section, a high-temperature clarification section, a transition connection section and a stirring section which are sequentially connected with one another; by arranging two outlets at the stirring section and improving the structure on matching adaptability, on the premise without influencing the existing production capacity of the platinum channel, the flowrate requirements that matching formation can be performed, and ultrathin TFT-LCD (Thin Film Transistor-Liquid Crystal Display) liquid crystal glass is produced are met, and the problems of uncontrollable quality indexes, including stress, warping and thickness difference, of a glass product causedby large flowrate, rapidness in glass plate speed, insufficiency in formation technology time, when the ultrathin glass is produced by original equipment are solved; in addition, on the premise of realizing the production capacity of two production lines, the usage amount of platinum is greatly reduced; and as the two production lines share the platinum channel at the front end, the investments ofpersons, equipment and plants can be greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of display glass production equipment, in particular to a double platinum channel structure for an ultra-thin glass substrate. Background technique [0002] As a new material for flat panel display glass, ultra-thin display glass plays a key role in the ultra-thin production process of TFT-LCD liquid crystal panels. At present, the mainstream technology in the market is the TFT-LCD liquid crystal glass substrate of 0.3-0.7mm, and the ultra-thin TFT-LCD liquid crystal glass substrate below 0.3mm has not yet been mass-produced in China. For thin glass, the flow rate is high. It is difficult to produce ultra-thin glass in high-generation or the glass forming speed is too fast in low-generation production. The process time for the glass to stay in the forming process equipment is not enough and the glass plate shakes greatly, resulting in stress and warping of glass products. Quality indicators such as curvatur...
