Polyester fiber non-woven

ordinary polyester spunbond non-woven fabrics with high strength, long life, can withstand high filtration velocity and other characteristics, the relative import filter their prices affordable, but filtering accuracy is not high. Emissions do not ask, particle size, dry, sticky dust filter.

① air permeability is measured in △ P = 200Pa.
② Filter efficiency: refers to the ratio of the number of particles the filter effectively blocking the number of dust particles into the dust. We are dedicated test stand with standard dust, run under the set conditions for 240 hours after the initial filter surface in the form of dust cake, and by a laser measuring instrument to calculate the number of import and export of dust measured. (The actual filtration efficiency of filter dust species, particle size distribution, dust concentration, filtration velocity, the dust collector structure, the use of the environment a number of factors)
③ The filtration precision: usually refers to the level of the minimum size in the original state is not established early dust cake, can effectively be blocked particles. In actual use, we can reduce the filtration velocity and the establishment of a stable initial dust cake and other measures to improve the accuracy of filtering.
