How to color transparent acrylic products?Acrylic processing plants use silk screen printing to color patterns. Need a darkroom, an exposure machine, screen printing workbench, wire mesh, photosensitive glue (Swiss imports), acrylic paint and propylene slow-drying agent, scraper, washing network.

Operation:
1)adjust the photosensitive glue
Generally buy the imported photosensitive adhesive needs to adjust itself, there is a small bottle of liquid inside, pour into the glue, stir it, this time the glue becomes green (must remember to adjust in the darkroom In the operation, the glue will be abolished. When it is used, it should be covered in a place away from light.) Then pour the glue into the scraper, scrape the photoresist on both sides of the screen, the scratch layer should not be too thick, but There can be no places to leak.

2)Putting photosensitive glue to the oven to dry.

3)Print the pattern to be printed with transparent adhesive tape
Placing the transparent adhesive tape on the glass plate of the exposure machine, press the screen cloth face down on the transparent adhesive tape, cover the cover of the exposure machine, and open the vacuum. Set the exposure time, usually about 30 seconds, after the air is exhausted, press the exposure button. At this time, it is best for people to leave the darkroom. The ultraviolet light of the exposure machine is not good for people. When the exposure ends automatically, you can take out the net and adhesive tape, take out the net and rinse it out. The part that is washed away is the part that is not illuminated by the light, that is, the pattern that needs to be printed (the screen is facing the light and there is no view outside the pattern) Small holes that are not covered by the photoresist, if necessary, the holes should be sealed with tape, otherwise the pigment will leak from the small holes when printing.) After the plate making is completed, the net is taken to dry.

4)Insert the net into the card slot at the front end of the screen printing workbench and lock it.
Put the acrylic plate on the printing table, put the net down, the pattern part is on the acrylic plate, adjust the color with propylene plus water and slow-drying agent, pour it on the net, then scrape the color with the scraper, let the color from the pattern part Small pores leaked and printed on acrylic. It's finished.
