2 Performance Test Items and Methods

Silkscreen mark and character performance requirements. The test items, test methods and technical indicators achieved are shown in Table 2.

3 Results and Discussion

3.1 Print Film Performance Test Results

The hardness, water resistance test, salt water resistance test, acid resistance test, alkali resistance test, and ethanol resistance test mainly test the performance of the printed film. Therefore, the stainless steel substrate used in these tests was tested. The test results are shown in Table 3.

3.2 substrate matching test results

The abrasion resistance of the ethanol test and the binding force test have different results for different substrates, and it is defined as a substrate matching test. The test method for the abrasion resistance of ethanol was to rub back and forth 50 times with a 500 g load on an ethanol-containing cotton yarn. The result should be no detachment and no abnormality. The test conditions of friction-resistant ethanol were summarized in Table 4.

Bonding test method according to GB4677.7-84 printed board coating adhesion test method Tape method, the measurement should be no peel off phenomenon. The results of the binding force tests are summarized in Table 5 after they have been summarized.
