Technical solutions for coating thickness gauges
1. What kind of coating material does the coating thickness gauge mainly measure?
Answer: The coating thickness gauge can measure the thickness of the non-magnetic coating on the magnetic metal substrate and the thickness of the non-conductive layer on the non-magnetic metal substrate.
2. Can the thickness gauge measure the thickness of the thread coating on the screw?
Answer: The thickness of the thread coating on the screw with a relatively small diameter cannot be measured by instruments in the current era.
3. Can the coating thickness gauge measure the coating of high-temperature materials?
Answer: The thickness gauge cannot measure high-temperature materials. In principle, it can only measure materials below 60 degrees.
4. Can the coating thickness gauge measure the thickness of the nickel coating?
Answer: No! Because nickel is both magnetic and conductive, the thickness of the nickel coating cannot be measured.
5. Can the coating thickness gauge measure the coating on non-metallic materials?
Answer: The current coating thickness gauge is not able to measure the coating thickness on non-metallic materials, it can only measure the coating of non-magnetic materials on iron base and the thickness of insulating layer on non-ferrous base metal materials.
Another: For the coating measurement of non-metallic substrate materials, electrolysis, X-ray, ultrasonic coating and other instruments can be selected at present, but all methods have advantages and disadvantages. Electrolysis will destroy the material, and X-ray thickness gauges are relatively expensive. The accuracy and stability of the coating thickness gauge is not very good. At present, many users use the era thickness gauge to measure through indirect methods, for example: spraying metal materials and non-metallic materials at the same time during the spraying process, and then measuring The thickness of the metal coating indirectly obtains the thickness of the spraying of non-metallic materials.
6. Can it measure the thickness of film and paper?
Answer: The thickness of films and papers that meet the thickness requirements can be measured by lining the metal substrate at the bottom. At present, there are many customers for this application.
