Is a high-precision coating thickness gauge used to select paints? Many people have this question. Generally speaking, measuring paint thickness and making choices are closely related to the accuracy and range of the coating thickness gauge. It is very reliable to choose paint with a high-precision coating thickness gauge.
So what is the principle and method of selecting paint with high-precision thickness gauge? What's the reason?
First, we will introduce the relevant knowledge of paint film. The state has clear and very strict regulations on the thickness of paint films, namely:
1.The thickness of the paint is generally not less than 75 microns
2.The middle paint film of the paint requires not less than 100 microns
3.The paint thickness of the topcoat is not less than 50 microns
4.The total dry paint thickness of the paint should be no less than 225 microns
It can be said that the paint thickness has a great relationship with its protection and abrasion resistance. If it is too thick, the most direct problem is the waste of resource costs, which will consume a lot of unnecessary paint. The second is that the dryness is not as good as the standard thickness. It will also reduce the binding force of the paint itself and the bottom plate. After a long period of use, it will be very easy to crack, glue and paint curling. If the paint thickness is too thin, the hardness of the material will be reduced and the protective ability will be reduced accordingly. This paint product is a quality problem, that is, a substandard product.
In view of the above two situations, the allowable error of the paint film thickness of the country is controlled within a very small range. That is, the deviation of the dry film thickness of the paint is -25 microns and the allowable deviation of each layer is -5 microns. Such small errors are often impossible to control manually, so a high-precision coating thickness gauge is a necessary equipment for manufacturers to perform self-tests.
High-precision coating thickness gauges have advantages that cannot be matched by ordinary coating thickness gauges. Traditional coating thickness gauges are largely affected by the surrounding environment and data measurement is also unstable. But for the high-precision coating thickness gauge, its design is quite intelligent. This advantage can ensure that the data is quite stable, there will not be much fluctuation and it shows great credibility. Therefore, high-precision coating thickness gauges are used to measure paint thickness. It is quite reliable to compare different products to make the correct choice.
Here we will introduce the LS223 high-precision coating thickness gauge of Linshang Technology. From a professional perspective, many paint self-inspection manufacturers or paint buyers will pay great attention to the accuracy of the detection instrument. This high-precision coating thickness gauge can detect coatings at different temperatures, that is, it has a strong temperature compensation function. When replacing the inspected substrate, the conversion can be completed within 0.5 seconds. Both the industry and novice operators can use it quickly.
In addition to the physical properties such as color and appearance, the thickness of the paint film is also one of the most important properties. In view of the principle of different paint film thicknesses, we use a high-precision coating thickness gauge to select paint.
