What are the issues that need attention when etching processing of optical inks？The problems that should be paid attention to in the process of using the photosensitive ink during etching are mainly the following points:1. Drying temperature and time: In order to achieve the effect of the coating, y

Ethymented processing iron, stainless steel, copper and other metals, especially iron SPCCs, can easily form a layer of rust on the surface. Must be processed.Metal rust is a local or comprehensive corrosion behavior caused by the contact of acid or alkali in the metal and the environment. The most

Improve the uniformity of the etch rate across the board surfaceThe etching uniformity of the upper and lower sides of the board and each part of the board is determined by the uniformity of the etchant flow on the board surface. During the etching process, the etching rates of the upper and lower p

The main problems that should be paid attention to in the process of using photosensitive ink before etching are as follows:1. Drying temperature and time: In order to achieve the effect of coating, a certain amount of solvent will be added to the photosensitive ink as dilution to adjust the viscosi

(1) Metal etching processThe type of metal is different, the etching process is also different, but the general process is as follows: metal etching plate → degreasing → water washing → etching → water washing → drying → screen printing → drying → water immersion for 2~3min → etching pattern Text →

Gravure printing is to fill the entire surface of the printing plate with ink, and then use a special scraping mechanism to remove the ink in the blank part, so that the ink only remains in the cells of the graphic part, and then under greater pressure ,Transfer the ink to the surface of the substrate to obtain printed matter.
