Embodiment
Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The invention provides a kind of disposal route of darkening ring, with reference to Fig. 1, in one embodiment, the disposal route of described darkening ring comprises the steps:
Step S10, provide darkening ring, the through hole that described darkening ring comprises body, is coated on the anti-static coating on described body and is formed on described body, described body is made up of plastic material, and described anti-static coating is carbon dust layer, and described through hole is formed by punching press.
Particularly, in the present embodiment, the thickness of described darkening ring is 0.025 millimeter, and the diameter of described through hole is 2.14 millimeters, and described body is made up of polyethylene terephthalate.
Because the manufacture of darkening ring is, first form body, again at the outer surface anti-static coating of body, finally on body, form through hole in the mode by punching press, at this moment, the hole wall of described through hole is formed by polyethylene terephthalate, so machine can be corroded by aqueous slkali, to form dumb light structure on hole wall, the remainder of darkening ring is then coated with the anti-static coating formed by carbon dust layer, it is poor to the susceptibility of aqueous slkali, substantially can not be subject to the corrosion of aqueous slkali, and then ensure that the feasibility of this forwarding method.
Step S20, by aqueous slkali corrosion on the hole wall of described through hole, form dumb light structure.
Particularly, with reference to Fig. 2, in the present embodiment, the described step forming dumb light structure by aqueous slkali corrosion on the hole wall of described through hole specifically comprises:
Step S21, aqueous slkali to be placed in ultrasonic generator.
Particularly, described aqueous slkali is sodium bicarbonate solution, and its concentration is 5% ~ 35%; The power of described ultrasonic generator is 300 ~ 500 watts, is preferably 400 watts.Ultrasonic generator sends ultrasound wave, to cause the vibrations of the sodium bicarbonate solution be placed in ultrasonic generator, and then ensure that corrosive effect.
