We all know that the function of the coating thickness instrument is to measure the thickness of the product appearance quality coating.
The magnetic thickness measurement method can measure the thickness of the non-magnetic covering layer on the magnetic metal substrate. When the magnetic coating thickness instrument is touched to the surface of the object to be measured, because the iron-based material is easily attracted by the magnetic force, the change of the magnetic flux of the object to be measured will induce a voltage signal in the probe detection coil. Moments are proportional.
The eddy current method (N-type probe) is to use high-frequency alternating current to generate an electromagnetic field in the coil. When the probe is in contact with the covering layer, an eddy current will be generated on the metal substrate and feedback to the coil in the probe. The thickness of the covering layer can be derived by measuring the magnitude of the feedback effect.
We know the coating thickness instrument, but it is not the reason. What are the benefits of the paint thickness measurement device for the user's product coating measurement?
The reason why most products are painted, electroplated, and sprayed with various coatings is to avoid corrosion or abrasion of the product appearance, because most product coatings are exposed to air and sweat on the user's hands, and are prone to This kind of object has friction.
Therefore, the thickness of the coating is very important for the product itself. If the coating is too thin, it will inevitably lead to corrosion and wear changes in the appearance of the product, which will give users a bad impression of the manufacturer's brand.
Therefore, it is necessary to use a coating thickness instrument to measure the thickness of the product's appearance coating.
From the first point, we know that a coating thickness instrument can be used to measure the thickness of the appearance of the product, but if the thickness of the coating is too thick, it will increase the cost of the coating or increase the appearance of the product.
The increase of paint will inevitably increase the cost of the product, and the thickness of the product coating will increase. How do users understand the cost of use?
As an example of aircraft coating, we know that when the thickness of the coating on the aircraft increases, the weight of the aircraft will inevitably increase, and the fuel consumption will also increase. Hundreds of thousands of flights will increase the user's cost a lot.
The production materials of most products are relatively single, and the feel and final appearance are also relatively simple. Therefore, through the additional coating, the appearance of the product can be diversified, and the feel will be much better than the original production material, which can improve the grade of the product.
The component coating of some electronic products is used for insulation or heat insulation. If the thickness of the coating does not meet the standard, the insulation and heat insulation will not meet the standard, and product damage or accidents are prone to occur.
Therefore, using a coating thickness instrument to measure the coating thickness of these electronic components can ensure their insulation and heat insulation performance.
Nowadays, the shells of many products are integrally stamped, and the external quality of the products is basically the same.
However, after the process of adding the coating, the spraying time of some areas may be long or unreasonable, resulting in partial deviations in the appearance and feel of the product. By using the coating thickness instrument, the consistency of the product's appearance and feel can be ensured.
Therefore, the coating thickness instrument is of great benefit to the appearance quality inspection of the company's products and the improvement of the economic benefits of the products.
For example, the automobile industry will use different types of instruments such as the magnetic coating thickness gauge, color difference meter, gloss meter and so on. It can not only make the appearance of automobiles favored by users but also reduce automobile maintenance costs.
