Description
Technical field
The present invention relates to a kind of platinum channel and a kind of glass manufacturing equipment and methods, exist in particular to one kind
In glass manufacturing process, platinum channel and carried out for solving glass in the platinum channel that high temp glass solution flows through
Clarification, bubble can not remove completely, influence the device and method of product quality, yield and production efficiency.
Background technology
In the manufacturing process of TFT, LTPS base plate glass and optical glass, kiln process melts batch into glass metal
It reaches afterwards after platinum channel process clarified, stirs, by being fed section, after flowing out platinum channel process, is sent to molding procedure
It is made into base plate glass boards half-finished product, finished product is made in semi-finished product after processing, and panel can be sent to by then completing packed and transported
Producer is used.
As technological progress and market are higher and higher to base plate glass and optical glass requirement, promoted in turn to glass
The requirement and market expectations of quality-improving, this requires the optical quality of base plate glass and optical glass is higher and higher, with previous
One or several diameters are less than the single isolated bubbles of 0.03mm on the defects of can tolerating a bit, such as every base plate glass, now
Into the unacceptable defect of panel producer, and the air blister defect of this specification is difficult complete in entire base plate glass processing procedure
It is discharged from finished glass.
In the manufacturing process of base plate glass and optical glass, glass batch is after kiln process is melted, often
Substantial amounts of bubble in association, these Air Bubble Sizes differ, the elimination work of bubble, mainly complete in the settling section of platinum channel process
Into.The temperature of settling section is often higher, reaches 1600 DEG C or more, the purpose for the arrangement is that in order to reduce the viscosity of glass metal,
Obtain preferable clarifying effect.But after bubble diameter is especially small, the working limit of platinum channel settling section is reached, with regard to nothing
For method completely by removal of bubbles, air blister defect will be formed in glass finished-product influences glass quality.
The situation of the above-mentioned elimination for being the bubble brought from kiln process also has a kind of bubble to be generated in platinum channel
Portion, it due to containing moisture in glass metal, will decompose in high temperature environments, hydrogen ion and oxonium ion be generated, due to glass metal
In containing a large amount of electronics, hydrogen ion and oxonium ion under electrochemical reaction, oxygen and hydrogen are formed, since platinum channel is mainly
It is made of noble metal platinum, platinum plays an important role of catalyst at high temperature, more promotes this electrochemical reaction, chemical formula is such as
Under：
H2O←→H++OH-←→H2+O2
More than electrochemical reaction is occurred mainly in close to the region of platinum channel inner tubal wall, since platinum has the work for oozing hydrogen
With hydrogen molecule is small, can be passed through in platinum inside configuration, however oxygen molecule can not pass through platinum structure due to bigger
Inside, i.e. hydrogen can penetrate platinum tube wall, and then oxygen molecule can not but penetrate.Due to the hydrogen partial pressure of platinum pipe pars intramuralis
It higher than the hydrogen partial pressure on the outside of platinum tube wall, therefore tends to occur, hydrogen oozes out inside platinum pipe, and oxygen is in platinum tube wall
Inside forms the phenomenon that oxygen bubbles.Moreover the glass flowing velocity in this region is relatively low compared to central area, it is easier to assemble shape
Into big bubble, the base plate glass of generation suffers from this, and product yield reduces.
The solution of above two bubble is mainly completed in settling section, therefore the settling section of platinum channel process is critically important
Functional section, directly affect the yield and quality of glass product.
In traditional base plate glass and optical glass processing procedure, both the above bubble is difficult to distinguish, and countermeasuress are to differ
Sample, and also condition each other.Solution to the problems described above mainly has at present, raises the temperature of platinum channel settling section, leads to
1640 DEG C or more often are increased to, especially in the case where production capacity is larger, temperature higher, it is to reduce sticking for glass metal so to do purpose
Degree so that bubble is easier to float and exclude, but while bubble is solved, can generate high amount of platinum volatile matter defect,
And influence the service life of platinum channel.
Simultaneously while platinum channel settling section temperature is raised, entire platinum channel is mounted in constant temperature and humidity
Portion, interior humidity is increased to more than 50% between constant temperature and humidity, and temperature is increased to 40 DEG C or more, it is therefore an objective to so that in constant temperature and humidity
More hydrogen partial pressure is generated, a dynamic moisture dissociation is formed on the outside of platinum channel settling section tube wall：
H2O←→H++OH-←→H2+O2
Rich hydrogen is generated, a dynamic balance will be generated inside and outside platinum pipe, and it is internal between constant temperature and humidity
Humidity and temperature are higher, and stability is better, and the hydrogen partial pressure of generation is higher, will offset and be oozed inside platinum pipe as far as possible
Hydrogen out avoids generating substantial amounts of oxygen bubbles influence product yield and quality near platinum inside pipe wall.
There is more than game method certain office to show property：
The rise of settling section temperature is limited be subject to platinum fusing point and elevated temperature strength, has certain limit, and temperature is got over
Height, the noble metal volatile matter brought is more, and the calculus defect of generation is also more；
Since the interior platinum channel equipment of constant temperature and humidity is more, and limited be subject to platinum channel size, constant temperature and humidity
Between be made big, length is at 15 meters or more, and all between 4 to 5 meters, the air circulation between constant temperature and humidity reaches 4 for width and height
To 6 ten thousand steres per hour, production cost is larger；
Due to the shape between constant temperature and humidity be subject to platinum channel equipment and layout influenced, above and below settling section and both sides without
Method is accomplished symmetrically, therefore settling section platinum pipe both sides and upper and lower temperature, humidity, air quantity and flow velocity are also highly non-uniform, temperature
Degree difference can reach 50 DEG C or more, and humidity difference forms system more than 30%, to the clarifying effect of platinum channel settling section
About；
It is worked wherein between constant temperature and humidity due to being frequently necessary to operating personnel, it can not be by temperature and humidity as far as possible
It raises to improve bubble countermeasure effect, for promoting the hydrogen partial pressure in constant temperature and humidity, similarly can not also obtain preferably clear
Clear effect.
It is then desired to a kind of device and method for improving glass clarifying effect, to improve the work of platinum channel settling section
Effect so as to improve glass quality, meets the market demand.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of platinum channels and a kind of glass clarifying effect of improving to set
It is standby and using the platinum channel and improve the equipment of glass clarifying effect and manufacture the method for glass, use the present invention's
Device and method can reduce platinum channel settling section or so and upper and lower temperature, humidity difference, reduce environment to platinum channel
The influence and restriction of settling section improve the hydrogen partial pressure outside platinum channel settling section, and bubble is eliminated so as to promote settling section
Ability improves the quality of glass product, reduces producing line operating cost, reaches requirement of the market to glass product.
