Corrosion-Resistant High-Efficiency Filter Paper For Filters HEPA Filter Paper
1.Product introduction
Filter paper is a scientific tool, it can effectively filter impurities, filter paper has been widely used in various fields. According to the different types of fibers that make up the filter paper, the performance and use 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.

3. Product nature
Hardness: The filter paper becomes wet during filtration, and some experimental procedures for long-term filtration should consider the use of tougher filter paper after wet water.
Filtration efficiency: The density and size of the seepage pores on the filter paper affect its filtration efficiency. High-efficiency filter paper provides fast filtration and high resolution.
Capacity: The solid particles accumulated during filtration may block the pores on the filter paper, so the denser the water seepage pores, the higher the capacity and the more filters that can be filtered.
Applicability: Some filter papers are made by special production steps, for example, in testing medicine for measuring nitrogen content in blood, nitrogen-free filter paper must be used.
4. selection factor
1. The effective area of the filter paper is large, that is, the use area of the filter paper is large, the dust holding capacity is large, the resistance is small, and the service life is long. Of course, the cost will increase accordingly.
2. The finer the fiber diameter, the better the interception effect and the correspondingly higher filtration efficiency.
3. The binder content in the filter material is high, the tensile strength of the paper is high, the filtration efficiency is high, the lint phenomenon is less, the background dust accumulation of the filter material is small, and the resistance is good, but the resistance increases accordingly.
