II. Process conditions


1. Oiling

Use it after mixing for 15 min thoroughly and leaving it alone for 15 min.


2. Pre-treat the substrate

3~5% sulfuric acid or hydrochloric acid for water cleaning, grinding defect for 15~20 mm, water film cracking for more than 10 sec, meshes of brushing roller 300 and 500, polish brushing current 2.5~3.0 A and drying temperature 80~120 ℃.


3. Printing

Screen 90~100T silk screen, scraping hardness 65~75, scraper angle 70~80°, inclination 20~35°, screen distance 4~6 mm, rest scraping rubber ≥15 mm, the length of scraper in one side is 10~20 mm longer than the printing graph, machine printing pressure 1.0~2.0 kgf/cm2, screen speed 50~70 HZ, printing film thickness 10~15 μm.


4. Curing

The energy of 5~8 kw mercury lamp or halogen lamp (mercury lamp) is above 1000mj/cm2, the distance to irradiate plate surface is 8~10cm and the usage time of lamp tube is controlled within 1,000 hours.
