When manufacturing and developing paints and varnishes, many different parameters lead to different properties of the final coating. Some of these properties are affected by the thickness of the coating and the application of paint or lacquer.
Manufacturers' efforts to achieve high quality and decorative features using less material has resulted in reduced coating thicknesses. Precise and repeatable inspection of such coatings is an important reason. For simple coating thickness measurements of wet films, so-called wet film measuring combs are used, which dip into the paint film up to the substrate surface.
When determining the coating thickness of dry coatings, non-destructive measuring electronics are used that quickly and accurately display the required measured value based on magnetic procedures such as Hall effect or eddy current.
In particular the modular QNix® 8500 measuring system can be easily adjusted to every measuring task on various types of measuring substrates - even duplex measurements - when combining various measuring probes. Wireless transmission measurements via radio from the probe to the meter are also possible.
Quality management during development and production using statistical analysis To ensure quality monitoring in the laboratory and production, coating Thickness Gauges and systems are required that, in addition to simply taking measurements, also provide advanced functions for documentation and statistics. Statistical analysis of the measurements made on the mean, standard deviation, minimum and maximum values provides an overview on the quality of the complete production batch.
This allows for quick implementation of successful measures to improve quality and throughput. Measurement documentation is achieved by simply transferring data to a PC and saving it for further analysis using a spreadsheet program. This provides a reliable, fast and convenient working method. For example, the new modular QNix® 8500 measurement system transmits measurement data using
Convenient wireless connection to PC. Since there are no exposed interface connections, the measurement transmission is protected from dirt and damage.
