The tape supplied is a replacement product for adhesion testing in the United States. Model, thickness, width, color, off-white (yellow), applicable scope of testing (high adhesion splicing), protection, sealing, packaging, etc. Hundred-grid test steps: Use a hundred-grid knife with a blade width of about ~ to draw (small) square grids on the surface of the test sample, spaced ~. Each scratched line should be deep into the bottom layer of the paint. Use a brush to brush the test area. Brush the debris clean? Use tape or equivalent adhesive tape to firmly stick to the small grid being tested, and wipe the tape vigorously with an eraser to increase the contact area and strength between the tape and the tested area. Grasp one end of the tape with your hand. Quickly pull off the tape in the vertical direction and perform the same test at the same position. The results determined that the adhesion required by mobile phone customers was qualified. Experimental Grade? Grade Grade (the edges of the cut are completely smooth, no peeling at the edges of the grid)? Grade Grade (small pieces of peeling at the intersection of the cuts, actual damage in the crosshatch area)? Grade Grade (there is some peeling at the edges and/or intersections of the cuts) Peeled off, with an area greater than ~ )? Grade level (partial peeling off or whole large pieces peeling off along the edge of the cut, or part of the grid peeling off completely. The peeling area exceeds ~ )? Grade level (large pieces peeling off along the edge of the cut/or some squares) Some or all of the paint peels off, and its area is larger than the marked area ~)? Grade level (there are pieces of paint peeling off at the edges and intersections of the marked lines, and the total area of the peeled off is greater than). Long-term agent for American test tape.
