What are the benefits of air filter paper curing?
Latest company news about What are the benefits of air filter paper curing?

Because the filter paper has to be under pressure for a long time during work, it is necessary to find a way to increase the strength of the filter paper, otherwise it will easily rot. Therefore, industrial filter paper must be processed by “dipping” process!


According to different processes, it can be divided into two categories: solidified filter paper and non-cured filter paper. Cured filter paper is generally impregnated with phenolic resin, and then baked at a temperature of 150-180 degrees for about 15 minutes to cure the resin and increase the sharpness of the filter paper. Here “cured filter paper” came out!

“Cured filter paper” is treated with high temperature, and the paper fibers are almost completely covered by resin. “Non-cured filter paper” generally uses polyvinyl acetate resin as the impregnating agent, and it is finished by dripping naturally after impregnation. Therefore, the hardness and stiffness of the filter paper are not as good as the “cured filter paper”. Moreover, “non-cured filter paper” is easy to absorb water and become damp, and at the same time, its high temperature resistance is not as good as “cured filter paper”. The materials of these two types of filter paper are the same, but the subsequent impregnation process is completely different! ——”Cured filter paper” is obviously better, more waterproof, acid-resistant, low-temperature resistant, high-temperature resistant, and alkali-resistant.
