Bag filter performance as a filtration device often used in our modern life, we all have a certain understanding, selection methods which us e filter bags, do we know how much of it Now and we look it!industrial fabrics
1, see the penetration
Generally speaking, the penetration rate of the filter media enough to reflect it run in the resistance, it will affect the strength of the work of filtration equipment and the pressure difference, and permeability are also many ways to calculate.
2, to see the ability to regenerate
In the use of the process of a filtering device, there is always a small amount of contaminants clogging the pores of the medium, which we can be flushed after the end of each working procedures, these contaminated particles from the surface of the medium as well as the porosity Clear maintain filtration performance of the media. And reproduction performance of the device mainly depends on the structure, composition and processing techniques, the filter medium.
3, look at the physical and mechanical prop erties
The physical and mechanical properties of the filter media including moisture absorption, abrasion resistance, mechanical strength, etc., will affect the performance and service life of the filter medium, the different structure of the device for media physical, mechanical performance requirements are slightly different s.
4, to see the chemical stability
Filtration equipment to be processed material is varied, acidic, alkaline, strong oxidizing as well as various organic solvents, etc. We therefore for the stability of the chemical properties of filter is to be of concern, so we choose a filter medium depending on the use to determine performance. For example, the polypropylene fiber has good acid resistance, alkali resistance and resistance to an oxidizing agent; Polyethylene fibers of the high stability of the acid, an alkali solution at a certain temperature; polyester material has a very good acid sex.
