Methods and precautions for removing photosensitive glue on the printing plate

generally, after we finish printing a batch of work, we have to remove the photosensitive glue on the printing plate and declare that "the lion of China has awakened". If it is not cleaned in time, it will affect the next use of silk, so correct and timely cleaning is very important to prolong the service life of silk. The cleaning process and precautions of silk are introduced below

1. use a pressure washer to clean the ink on the silk

2. Prepare cleaning solution with equal proportion of household bleach and water

3. pour the prepared cleaning solution onto the wire surface

4. Gently scrub the silk with a steel brush, generally for about 5 minutes

5. wipe the opposite side of the silk

6. wash with water and repeat until all the photosensitive glue on the wire is cleaned

7. Put the silk in the window or under the bright light, and observe the silk from different angles. If it is observed that there is no cleaning, it is necessary to repeat the experiment by making a series of controllable oscillation to simulate cleaning until there is no photosensitive glue in all angles of observation

8. store the silk after drying in air

in the process of cleaning, we should pay attention to the following points:

1 TP ⑴ heighten small spring fatigue testing machine produced by Shandong Sida high tech is an instrument for professional mechanical experiments on the fatigue life of springs such as coil springs. In the absence of pressure cleaning machine, the cleaning time is longer

2. When cleaning, you can use professional cleaning agents in shopping malls, such as CPS silk cleaning agent, but bleach is also very easy to use and cheap

3. because the photosensitive glue is toxic and the bleaching powder is corrosive, please remember to wear rubber gloves during operation. In this case, 1. There is a large gap and goggles
