aluminium sheet fabrication.The method of screen printing test for baking paint of aluminum alloy die casting was reviewed

　　1. Screen printing friction test, use 3M600 tape close to the screen printing surface, the other end of the hand-held tape is quickly pulled away from the side at a 45 degree Angle, repeat the same position 3-4 times, check that the screen printing on the tested surface is intact, and the screen printing is rejected when it falls off. At the same time, use a 95% alcoholized cotton ball to force 5-6Kg back and forth for 3 times without fading color, no color depth change. Sassafras test

　　2. Screen printing friction test: the tested part is fixed on the dynamometer, and the soft rubber is used to wipe the screen printing part back and forth. The strength of the dynamometer is measured at plus or minus 0.1-0.5KG once, and the test is 950-1000 times.

　　3. Wipe the tested surface with 95% alcohol solution with a cotton swab for 3-5 times, air dry and observe the screen print of the test surface. The surface of the tested surface should be dull, without touching hands or being dissolved.

　　The above is our method to test whether the silk screen printing of aluminum alloy die casting paint is qualified. If you know more about the wear resistance test method of silk screen printing, welcome to leave a comment in the following!
