Enamel is mostly made of inorganic glass. Its thickness is usually tester by magnetic thickness gauge.

In China, fired enamel protective layer has always been a relatively common protection measure. With the development of the times, the exercise technology of the enamel protective layer has also been developed, but the actual effect is still inseparable from the endogenous and exogenous influences. This article mainly explores the relationship between various factors and the performance of the enamel protective layer. Enamel protective layer thickness measurement tool-magnetic thickness gauges are also introduced in this article.

1. What internal factors affect enamel protective layer?

(1) Thickness of enamel protective layer

In general, the actual effect of the enamel protective layer is not directly proportional to its thickness, they are usually curvilinear. As the thickness of the enamel protective layer continues to increase, it will cause cracking problems. If the thickness is too thin, it will affect the uniformity of the protective layer surface, which is not conducive to completely covering the internal metal. Its protection performance is lacking.

(2) Enamel protective layer composition

The constituent materials of the enamel protective layer are nothing more than mineral raw materials and chemical raw materials. These are inorganic components in the chemical sense. On the one hand, they can block the external air. The anti-friction effect of long-term use of it is very prominent. On the other hand, inorganic materials are relatively low in electrical conductivity and thermal conductivity, and can be used for a long time in the external environment.

2. What external factors affect enamel protective layer?

(1) Firing process

The firing process mainly needs to avoid some minefields that cause the enamel protective layer to break. For example, after a period of high-temperature firing, it should not be immediately irrigated with cold water, which will shorten its service life. Modernized enamel protective layer technology has changed to biotechnology and new material automation technology.

(2) Burning time

Professionals also need to pay attention to the operation time during the firing process. Too short or too long firing time is not conducive to the perfect solidification of enamel and will lead to rapid aging of enamel in future life use. If the firing time is too long, it is easy to find that the surface color of the enamel protective layer changes and its aesthetics is affected to a certain extent.

3. Magnetic thickness gauge test enamel layer thickness

The actual performance of the enamel protective layer depends on many factors, the manufacturer will start from the aspect of easy control. For the mastering of the firing process and firing time, manufacturers often choose experienced operators to work. The constituent materials of the enamel protective layer are generally common mineral raw materials. For the evaluation of the enamel protective layer thickness, in most cases, a very professional magnetic thickness gauge is selected for detection.
       The magnetic thickness gauge is a paint thickness measuring instrument specifically for non-metallic protective substances on the metal substrate. We will choose the appropriate range of magnetic thickness gauges according to the actual product. Generally speaking, the error of the magnetic thickness gauge will not exceed 10%. From a functional point of view, low energy consumption and measurement automation are its important work characteristics. When we use a magnetic thickness gauge to evaluate the actual performance of the enamel protective layer, we will keep the average thickness of a batch of products between 0.15mm and 0.5mm. This product has a strong ability to tension and equalize pressure.
