Materials and types
The filter paper is made of one or more of inorganic fiber, plant fiber, and synthetic fiber, adding the appropriate amount of chemical auxiliaries and fillers, and is made by papermaking technology. It is a kind of filter media and s a scientific tool that is porous and has good filtration performance.
Currently, filter paper has been widely used in various fields. However, because of the different types of fibers constituting the filter paper, the performance and use of the filter paper are different.
There are ordinary filter papers for general occasions, glass fiber filter papers for high temperature, and polypropylene filter papers for ultra-clean and so on. Based on the usages, it can be divided into paint filter paper, paint mist filter paper and grinder filter paper.
