Abstract
The invention provides a method which mainly comprises the following steps: (1) LOT composition: performing the LOT composition according to the LOT order generated by the flow process of the previous process step: (2) cleaning with sulfuric acid; (3) cleaning with pure water; (4) cleaning with IPA (isopropanol); (5) drying with a drying box; and (6) sending to next flow process. The method reforms the traditional drying manner, and the main method is mainly characterized in that industrial alcohol for drying a glass sheet in the traditional method is replaced with isopropanol (IPA). By adopting the method, the dirty defective rate of products and the poor adhesion after dryness can be effectively inhibited, the yield rate can be improved, and the method is safer.
Description
Technical field
The present invention relates to a kind of cleaning and drying method of sheet glass.
Background technology
Cleaning-drying at sheet glass, what adopted is that industrial alcohol cleans the back drying in the past, its shortcoming is the relatively low easy volatilization of boiling point (64.7 ℃) of industrial alcohol, cause when cleaning article, being difficult for relatively cleaning, can find that after oven dry there is the adhesion of sheet glass and dirty bad in more situation.Simultaneously, the industrial alcohol main component is a methyl alcohol, and toxicity is bigger, causes its security low excessively.
Summary of the invention
Cause dirty and adhesion etc. bad easily in order to solve traditional alcohol wash, and the low problem of security, the present invention proposes following technical scheme:
A kind of sheet glass cleaning and drying method is characterized in that, this method mainly may further comprise the steps:
(1) LOT constitutes, and carries out according to the LOT order that the flow process of preceding working procedure generates;
(2) sulfuric acid is cleaned;
(3) pure water is cleaned;
(4) IPA cleans;
(5) drying box oven dry;
(6) deliver to next flow process.
Further, described method uses the IPA that is different from conventional clean solution to carry out.
Further, described IPA solution can be recycled, and utilizability is strong, and chemical characteristic has determined safer with respect to industrial alcohol.
The beneficial effect that the present invention brings is:
1, used aqueous isopropanol as after the cleaning fluid, glass sheet surface more cleans, and has effectively suppressed the appearance of dirty bad and adhesion, has improved yield of products.
2, use the processing quantity of equivalent cleaning fluid effectively to increase in the process, IPA solution can clean more products under square one.
3, isopropyl alcohol (IPA) solution of the present invention's employing, boiling point higher (82.5 ℃) is not volatile relatively, and its chemical safety is higher, under normal job specification there is not any injury in the operating personnel.
The specific embodiment
Below preferred embodiment of the present invention is described in detail, thereby protection scope of the present invention is made more explicit defining so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that.
A kind of sheet glass cleaning and drying method is characterized in that, this method mainly may further comprise the steps:
(1) LOT constitutes, and carries out according to the LOT order that the flow process of preceding working procedure generates;
(2) sulfuric acid is cleaned;
(3) pure water is cleaned;
(4) IPA cleans;
(5) drying box oven dry;
(6) deliver to next flow process.
Described method uses the IPA that is different from conventional clean solution to carry out; IPA solution can be recycled, and utilizability is strong, and chemical characteristic has determined safer with respect to industrial alcohol.
The above; it only is the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
