The introduction of corrosion resistance and dielectric properties of the steel-plastic composite belt
Oct 31, 2017

The use performance of the steel-plastic composite belt is often determined by its comprehensive performance. Therefore, it is necessary to consider the corrosion resistance and dielectric properties of the steel-plastic composite belt at this time. Here we will analyze and introduce the content around the two aspects, hoping to help you.

 

This is because in the practical application, the working environment of the steel-plastic composite belt may be in the acidic or alkaline environmental conditions. Therefore, it is necessary to judge according to its corrosion resistance. In short, in fact, according to the copolymer film and the metal substrate between the layers will appear, and then whether the metal tape corrosion will be analyzed.

Therefore, when we are conducting the verification, we need to select a number of steel-plastic composite belts for 480 hours in the HCL solution with a concentration of 0.1 mol/L. Then we can judge whether the product is qualified according to the actual results. If you want to know more about its corrosion resistance, we can gradually increase the concentration of the solution used in the test. From the test results we can understand that in fact, the corrosion resistance of products produced by different manufacturers is very different.


However, on the whole, in the steel-plastic composite belt, compared to

the chromium-plated steel belts with higher corrosion resistance, the corrosion resistance of the non-chromium-plated steel belt is much worse. So, what about the dielectric properties? At this time, the verification will also need to be carried out in accordance with specific standards.


When verification, we found that the dielectric strength of the double-faced steel-plastic composite belt produced by the factory is in accordance with the standard requirements, and also has a large safety factor. That is to say, in the practical application, the double-faced steel-plastic composite belt can meet the requirements of various aspects.
