Abstract
The invention relates to a cover board glass washing process. The cover board glass washing process includes the following steps that firstly, after being washed, a cover board is printed with ink and dried, a plasma machine is not used, glass of the printed and dried cover board is directly washed through an ultrasonic washing machine, and anionic surfactant liquid medicine in the ultrasonic washing machine is replaced with nonionic surfactant liquid medicine, wherein the temperature is set to be 60 DEG C, and the washing time is set to be 4 minutes; secondly, the HLB value of a nonionic surfactant is adjusted between 12 to 15, the surface of the glass of the cover board can be damped at the water temperature of 60 DEG C, grease is removed, and the water drop angle of the glass of the cover board can be reduced to within 30 degrees. The steps of the cover board glass washing process are simple, a chemical reaction mode is used for replacing a traditional process for reducing the water drop angle through the plasma machine, the bad phenomenon that the glass of the cover board is scratched in the transfer process can be avoided, the yield is increased, capacity is improved, and production cost is greatly reduced.
Description
Technical field
The present invention relates to a kind of cover-plate glass cleaning.
Background technology
Cover-plate glass element sheet (such as hand-set lid glass, panel computer glass, flat panel TV cover-plate glass, industrial business touch-screen cover-plate glass etc.) the dirty impurity of shaping rear Ultrasonic Cleaning, then printing-ink is carried out, according to customer requirement generally to carry out 5-9 time not isochrome sequence repeatedly print, often print an ink and all will carry out lower sequence printing of the same colour again after baking box is dried, ink grease of giving out of ink after the baking not wait for 5-9 time drops on glass surface, glass surface water droplet angle is made to have 20 ° to rise to 90 °, cause next processing procedure because water droplet angle too high (customer requirement < 60 °), cause bubble cannot to fit production, current use plasma (plasma machine) 800 ° of high-temperature process glass surfaces reduce water droplet angle with this, because plasma machine is the bottleneck produced, and day night shift also respectively needs 3 people just can complete the production of this operation, so plasma needs to carry out technological improvement.Plasma uses finished product supersonic wave cleaning machine to clean (finished product ultrasonic wave uses 18 megohm pure water and the cleaning of anion surfactant liquid) after reducing water droplet angle, test again, the non-defective unit of inspection carries out AF anti-fingerprint plated film, detect with the cleaned current of developing machine after plated film, non-defective unit carries out packaging shipment, this process is complicated, and production efficiency is low, and product fraction defective is high.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of cover-plate glass cleaning.
Cover-plate glass cleaning of the present invention, comprises the following steps:
1) printing-ink and baking is carried out after cover plate cleaning, do not use plasma machine, directly the cover-plate glass after printing baking is adopted supersonic wave cleaning machine cleaning, change the anion surfactant liquid inside supersonic wave cleaning machine into non-ionic surface active agent liquid, temperature is set to 60 DEG C, and scavenging period is 4 minutes, because non-ionic surface active agent has hydrophily, the grease on cover-plate glass surface can be removed, also can wash the greasy dirt inside supersonic wave cleaning machine;
2) between non-ionic surface active agent HLB value debugging 12-15, can soak cover-plate glass surface at water temperature 60 DEG C, remove grease, the water droplet angle of cover-plate glass can drop within 30 °.
Compared with prior art beneficial effect of the present invention is: cover-plate glass cleaning step of the present invention is simple, replacing tradition by chemical reaction mode uses plasma machine to reduce the technique at water droplet angle, can reduce cover-plate glass in circular flow there is scratch bad phenomenon, not only promote yield but also can promote production capacity, production cost reduces greatly.
Detailed description of the invention
Below in conjunction with embodiment, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
A kind of cover-plate glass cleaning, comprises the following steps:
1) printing-ink and baking is carried out after cover plate cleaning, do not use plasma machine, directly the cover-plate glass after printing baking is adopted supersonic wave cleaning machine cleaning, change the anion surfactant liquid inside supersonic wave cleaning machine into non-ionic surface active agent liquid, temperature is set to 60 DEG C, and scavenging period is 4 minutes, because non-ionic surface active agent has hydrophily, the grease on cover-plate glass surface can be removed, also can wash the greasy dirt inside supersonic wave cleaning machine;
2) between non-ionic surface active agent HLB value debugging 12-15, can soak cover-plate glass surface at water temperature 60 DEG C, remove grease, the water droplet angle of cover-plate glass can drop within 30 °.
Cover-plate glass cleaning step of the present invention is simple, replacing tradition by chemical reaction mode uses plasma machine to reduce the technique at water droplet angle, can reduce cover-plate glass in circular flow there is scratch bad phenomenon, not only promote yield but also can promote production capacity, production cost reduces greatly.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and modification, these improve and modification also should be considered as protection scope of the present invention.
