Coating technology: coating film thickness measurement

Core tip: the film thickness is the most basic condition to ensure the physical and chemical properties of the coating The film thickness has a great impact on the performance If the film is thin, the protection ability of the coating is low, which does not reflect the significance of coating If the film thickness is thick, the cost will rise, and the performance will change At present, the film thickness gauges used in the laboratory are magnetic flux type and ultrasonic type There are many metal materials tested Determination method: 1 First, calibrate the film thickness gauge and meet the test requirements 2 Put the projection film on the metal plate with the probe of the film thickness meter Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Coating home news: film thickness is the most basic condition to ensure the physical and chemical properties of the coating The film thickness has a great impact on the performance If the film is thin, the protection ability of the coating is low, which does not reflect the significance of coating If the film thickness is thick, the cost will rise, and the performance will change At present, the film thickness gauges used in the laboratory are magnetic flux type and ultrasonic type There are many metal materials tested Determination method: 1 Calibrate the film thickness meter and meet the test requirements 2 Put the projection film on the metal plate and test its thickness M1 with the probe of the film thickness meter 3 Then test the film thickness m2 of the spraying part of the probe 4 The thickness of the film is m3 = m2-m1 Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
