Filter paper is made from one or more of inorganic fibers, plant fibers and synthetic fibers, adding appropriate amount of chemical additives and fillers, and using papermaking technology. It has good filtering performance, loose and porous. filter media. As a scientific tool, it can effectively filter media, and filter paper has been widely used in various fields. However, due to the different types of fibers that make up the filter paper, the properties and uses of the filter paper are also different. There are ordinary filter paper for general occasions, glass fiber filter paper for high temperature, and ultra-clean polypropylene filter paper.

Hardness: the filter paper will become wet during filtration. For some long-time filtration test steps, the stronger filter paper after wet water should be considered.Filtration efficiency: the density and size of water seepage holes on the filter paper affect its filtration efficiency. The high efficiency filter paper has fast filtering speed and high resolution.Capacity: the solid particles accumulated during filtration may block the small holes on the filter paper. Therefore, the denser the water seepage holes are, the higher the capacity is, and the more filtration is allowed.Applicability: some filter papers are made by special steps, for example, nitrogen free filter paper must be used to determine the nitrogen content in blood in laboratory medicine.
The effective area is large, that is, the use area of the filter paper is large, the dust capacity is large, the resistance is small, and the service life is long. Of course, the cost will increase accordingly.The finer the fiber diameter, the better the interception effect and the higher the filtration efficiency.The content of binder in the filter material is high, the tensile strength of the paper is high, the filtration efficiency is high, the hair loss phenomenon is less, the background dust accumulation of the filter material is small, and the resistance is good, but the resistance increases correspondingly.
