Abstract
The invention relates to a regeneration method for a glass substrate used by a flat panel display device. The method comprises the following three steps: exposure processing, demoulding processing, and cleaning processing. Moreover, an exposure dose of an exposure machine is 80 to 100 Mj/square centimeter and there is no need to place a chromium plate above a glass substrate during the exposure processing; a demoulding solution has the following components, by weight: 28% to 32% of glycol amine and 68% to 72% of dimethyl sulfoxide; a demoulding solution temperature is 40 to 55 DEG C and demoulding time is 110 to 130 cm/min; and a cleaning solution is pure water with a temperature of 40 to 45 DEG C; and cleaning time is 2 to 4 mins. According to the invention, a full exposure measure of not placing a chromium plate on a glass substrate is taken; and a technical scheme of using a demoulding solution that has a few components and a reasonable ratio is utilized; therefore, the generated glass substrate has advantages of full exposure, completely demoulding and simple process.
Description
Technical field
The present invention relates to a kind of glass plate and the processing method when unusual occurs at the preparation flat-panel display device, particularly a kind of flat-panel display device is with the renovation process of glass substrate.
Background technology
Flat-panel display device like liquid crystal display device etc., constitutes from seeing in appearance by two glass substrates, is commonly referred to forward and backward substrate, or upper and lower substrate, and preparation has luminous or control unit respectively on these two substrates.In these unit processes of preparation, make the unit that is prepared into fail to reach designing requirement because of various reasons, do not meet designing requirement like technical indicators such as thickness, uniformity, live width, line-spacings.As these do not meet the designing requirement unit can not to take off (removal), and glass substrate can not re-use, and cause great waste.At present, the method commonly used of this area is directly to corrode strip-up, and the glass substrate that is about to desire demoulding is directly inserted in the liquid parting and corroded, and getting final product through cleaning again.This method seems simply, and still, in fact demoulding is unclean, and the glass substrate after the regeneration does not still reach instructions for use.
The content of invention
In order to overcome the deficiency of above-mentioned prior art, the purpose of this invention is to provide the renovation process of a kind of flat-panel display device with glass substrate, have the glass substrate of making exposure fully, clean, the technology characteristic of simple of demoulding.
To achieve these goals, the technical scheme that the present invention adopted is: a kind of flat-panel display device carries out with the renovation process of glass substrate according to the following steps:
1, exposure:
Exposure is the 80-100Mj/ square centimeter, and during exposure, the glass substrate top need not to place chromium plate; Glass substrate is placed in the plate putting machine before the exposure machine, opens plate putting machine, exposure machine, unloader, exposure machine is accomplished the exposure of glass substrate automatically;
2, demoulding:
The liquid parting temperature is 40-55 ℃, and the demoulding time is 110-130cm/ minute;
The glass substrate that had made public is placed in the plate putting machine before the stripping machine, opens demoulding front amplifying board machine, stripping machine and unloader, stripping machine is accomplished the glass substrate demoulding automatically;
3, clean:
Glass substrate behind the demoulding cleans through rinse bath, and the temperature of rinse water is 40-45 ℃, and scavenging period is 2-4 minute.
The mass ratio of described liquid parting component is glycol amine 28-32%, dimethyl sulfone 68-72%.
When said demoulding was glass substrate process demoulding groove, the demoulding soup was sprayed the process of glass baseplate surface.
Said rinse water is sprayed the pure water of the glass baseplate surface behind the demoulding.
Because the present invention has adopted the exposure measure of on glass substrate, not placing chromium plate, makes the repeat glass substrate obtain abundant exposure, has used the liquid parting of reasonable mixture ratio to make demoulding thorough in addition, technology is simple.
