Abstract

The invention belongs to the technical field of optical lenses, and particularly relates to ink fading powder and a use method thereof, and the ink fading powder comprises the following components by weight: 28-42 parts of a surfactant, 20-36 parts of dibutyl maleate, 18-30 parts of a stripping agent, 3-6 parts of an activator and 7-11 parts of a composite additive. According to the ink fading powder provided by the embodiment of the invention, the surfactant, the dibutyl maleate, the stripping agent, the activating agent and the composite additive are compounded according to a reasonable proportion to form the ink fading powder, so that ink can fall off from the surface of optical glass, no ink is left after ink fading, the loss caused by defective products is reduced, and the production benefit is improved.

Description

technical field [0001] The invention belongs to the technical field of optical lenses, and in particular relates to a toner-removing powder and a using method thereof. Background technique [0002] Optical glass camera lens is a structural component of mobile phone products, the process is relatively complicated, and the manufacturing cost is high. [0003] Optical camera lenses are processed by glass raw materials through a series of complex processes such as cutting, laser, etching, tempering, silk screen printing, coating and full inspection. During the processing of each process, some defective products will inevitably be produced without any remedy Measures, defective products can only be scrapped. With the existing lens product processing flow, a large number of defective products will only be detected when the finished product is fully inspected. At this time, the value of the finished lens product is close to the sales price, and the scrap loss ratio is high. cause ...
