In today's industrial enterprises, the production environment in many places is not very good, so in order to ensure the quality of the products, many times, the filtering device is used, and the endurance board is the most common one, for endurance. For the board, we usually use it frequently during construction, because such materials have good performance characteristics, so we will be more convenient when using it. First of all, we must have certain heat resistance, we must ensure At high temperatures, it can also be used normally. Secondly, it must be easily separated for dust impurities. The dimensional stability is good. The glass fiber itself does not shrink at the standard temperature. The most important thing is to have certain corrosion resistance. Because in the industry, there are often many processing materials when processing, some are acidic and some are alkaline, so the corrosion resistance of the endurance board must be strong, because the brass plate has these characteristics, our industrial Development will get better and better.
