Description
Technical field
Glass production field is the utility model is related to, in particular it relates to a kind of platinum channel for being used for reducing platinum calculus.
Background technology
In TFT, LTPS base plate glass manufacturing process, kiln process reaches platinum after batch is melted into glass metal and led to
Procedure carries out clarification and homogenization, and glass metal is sent to molding procedure after platinum channel process and is made into glass boards half-finished product,
Finished product is made in semi-finished product after processing, and then completion packed and transported can be sent to panel producer and be used.
As technological progress and market require more and more higher to the display precision of display panel, promote in turn to substrate
The requirement and market expectations of the increased quality of glass plate, this require the calculus quantity in base plate glass reduce as far as possible or
There is no calculus defect.In the manufacturing process of base plate glass, produce glass stone defect the reason for have equipment composition material reason.
Because in base plate glass processing procedure, glass is after kiln process is melted, it is necessary to carry out quality by more than 10 meters of platinum channel
Adjust to eliminate bubble and striped, and in the processing procedure of platinum channel process, whole glass needs the temperature range of work to exist
Between 1150 DEG C -1650 DEG C, this high temperature and it is high corrode in the environment of, the precious metal material of platinum channel mainly have platinum and its
Alloy is made, and the melting that will produce platinum separates out and volatilized condensation, and as the raising of process requirements temperature and platinum lead to
Extension content in road working environment is higher, and this precipitation and volatilization will raise.These platinums separate out and the platinum material of volatilization
After material enters the glass by platinum channel, platinum calculus defect will be formed in base plate glass product, so as to influence base
The quality of glass sheet.
Fig. 1 is the schematic diagram of existing platinum channel settling section, and as described in Figure 1, existing platinum channel includes platinum pipe
(1), settling section entrance (6), settling section export (7), are wrapped in the peripheral heat-insulation layer (5) of platinum pipe (1), for platinum channel
Electrode (4) that the glass metal of interior flowing is heated and the blast pipe (8) connected with the platinum pipe (1) of settling section.Wherein, phase
Adjacent two electrodes (4) apply voltage composition electrical heating loop, are heated to flowing through glass metal therein.Under normal circumstances, should
The platinum pipe of platinum channel is made up of platinum or platinum alloy, and in glass plate processing procedure, glass metal enters from platinum channel settling section
Mouth (6) enters, and glass metal represents that direction is flowed along arrow, is flowed out from settling section outlet (7), platinum pipe (1) and liquid level line (2)
The upper space (3) of formation is full of air, precipitate and volatile matter and discharged from blast pipe (8), so as to reach to the clear of glass metal
Cleaning function.
But existing platinum channel settling section is in place of platinum calculus defects controlling Shortcomings, easily clear
Platinum precipitate and volatile matter are produced in the upper space (3) of clear section (1), and blast pipe (8) is outside empty due to directly contacting
Between, itself is less than the temperature of upper space (3) with exterior space temperature so that platinum separates out and volatile matter coagulates on platinum pipe
Tie and fall, produce platinum calculus, limit the further lifting of glass quality, can not more preferably meet the market demand.
It is then desired to a kind of platinum channel for being used for reducing platinum calculus, further to improve the quality of glass plate, meets
The market demand.
