What are the advantages of the coating thickness gauge compared with the coating thickness gauge?
Coating Thickness Gauge is a newly developed new product. Compared with previous coating thickness gauges, it has the following main advantages:
1. Fast measurement speed: the measurement speed is 6 times faster than other TT series;
2. High precision: The product is calibrated with a simple 0, and the precision can reach 1-2%.
3. Stability: The stability of the measured value and the use stability are better than those of imported products;
4. Function, data, operation and display are all in Chinese;
The protection of the material surface, the covering layer formed by decoration, such as coating, electroplating, coating, adhesive layer, chemically generated film, etc., is called coating in relevant national and international standards. Coating thickness measurement has become an important part of the quality inspection of the processing industry and surface engineering, and it is a backup means for products to meet excellent quality standards. In order to internationalize the products, my country's export commodities and foreign-related projects have clear requirements on the thickness of the cladding.
The measurement methods of coating thickness mainly include: wedge cutting method, light interception method, electrolysis method, thickness difference measurement method, weighing method, X-ray fluorescence method, β-ray backscattering method, capacitance method, magnetic measurement method and eddy current measurement method Wait. Among them, the first five methods are destructive detection, the measurement method is cumbersome and the speed is slow, and most of them are suitable for sampling inspection.
X-ray and beta-ray methods are non-contact and non-destructive measurements, but the devices are complicated and expensive, and the measurement range is small. Due to the presence of radioactive sources, the user must observe radiation protection regulations. The X-ray method can measure ultra-thin coatings, double-layer coatings and alloy coatings. The beta-ray method is suitable for measuring coatings and substrates with atomic numbers greater than 3. The capacitive method is only used to measure the thickness of insulating coatings on thin conductors.
