Non-stick coating thickness: The standard requires that the average thickness of frying pans and woks is greater than or equal to 25 microns;aluminum nonstick cookware the average thickness of boiling pans and milk pans is greater than or equal to 20 microns. This is an important indicator of non-stick pan,aluminum nonstick cookware which will affect the service life and performance of non-stick pan. In addition,aluminum nonstick cookware the surface of the non-stick pan needs to be sandblasted before coating to increase the surface roughness and increase the adhesion,aluminum nonstick cookware thereby increasing the adhesion fastness and scratch resistance.
Adhesion fastness,aluminum nonstick cookware the standard stipulates: immerse the sample in boiling water for 15 minutes and take it out, cool it to room temperature and wipe it dry with a soft cloth. Use the tip of a sharp single-sided blade and a steel ruler or a special grid template to score 11 parallel scratches 2.4mm apart and 38mm long on the coating,aluminum nonstick cookware and then repeat the above steps in the direction perpendicular to the scratches.
Must penetrate the coating to the metal. Use a single-sided transparent pressure-sensitive adhesive tape to adhere to the scratch area,aluminum nonstick cookware and the tape sticking direction is parallel to a set of scratch lines. Rub the tape with your fingernails to drive out the air at the adhesive location of the tape and make it adhere to the coating to the greatest extent.
Pull one end of the tape with your fingers,aluminum nonstick cookware and quickly pull it up at a 90° right angle for 3 times in a row,aluminum nonstick cookware using a new tape each time. Rotate the scratch 90° and repeat steps 3 and 4 with a new tape. After the test,aluminum nonstick cookware the coating in the grid area does not fall off completely. The test is mainly to prevent the coating from falling off, aluminum nonstick cookware thereby affecting the non-stick effect.
