Plastic mesh screen is one of the most popular used screen materials in the market, it is also insulating. With the development of science and technology, we have an increasingly big demand for the screen materials, therefore, we would put high emphasis on the special performances of the screen materials. In this case, we successfully invent and develop the plastic mesh screen, which is now widely used in many places.
In this essay, it will briefly tell us the quality conditions of plastic mesh screen, especially when we want to buy plastic mesh screen, we should know the criteria to determine whether the plastic mesh screen is good or not, we should specially pay attention to the quality of plastic mesh screen, so that we can maximize the usage of them.
Generally speaking, if we want to know the quality status of plastic mesh screen, we can check from below aspects. We can check the cross section of plastic mesh screen. When the plastic mesh screen is cut, we can check the section status. Even and smooth yellow or pale yellow sections mean the normal status of plastic mesh screen. When there are black spot or concavities, and their distribution is spread, then they will have severe influence on the performances and functions of plastic mesh screen. If there are red spots on the sections, that means the iron is oxidized.
We can also check the appearance colors of plastic mesh screen. The normal colors of plastic mesh screen are white, pale yellow and brown. But they can also be dark brown if they have high percentage of iron. We can check the appearance defects of plastic mesh screen. We can check from different aspects, namely falling out angles, softening deformation, cracks and chaps. For example, for silicon plastic mesh screen, the cracks and chaps are generated because of the stress in the plastic mesh screen.
We can know how to judge the quality of plastic mesh screen, so we can have a good understanding when we buy plastic mesh screen.
