Q:Filtration efficiency of liquid filter bags
Usually used for depth filtration had a bag of polypropylene, polyester, NOMEX, Teflon and other materials, the material internal structure, the thickness of the non-woven filter materials, the surface of the fiber will have an impact on the interception efficiency of depth filtration. Usually, this filter is also called relative filtration, and the filtering accuracy is usually defined by the filtration efficiency of impurities of an aperture. Different companies on the filter bag accuracy testing methods and the required filtering efficiency is not the same, some are defined as 80~85%, and some are defined as 50~70%.
Q:What are the materials commonly used in liquid filtration bags?
1, good heat resistance, can be used at 280 degrees Celsius for long-term use2 、 dust easy to peel off3. Good dimensional stability. Fiberglass does not shrink at standard temperatures
Q:What are the general models of filter bags?
Each bag manufacturers designation may not the same, the difference is the size of the bag material, as far as I know, the filter material: nylon, polypropylene, polyester, stainless steel, PTFE, filter size according to distinguish between: No. 2, No. 1 bag bag, 5 bags, 4 bags, 3 bags (from large to small), the other is non-standard.
Q:Will the size of the tea filter affect the tea taste?
Of course, the tea filter bag assembly affects tea flavor
Q:What's the correct way to use the filter bag in the dust collector?
Bag filter used in the process need to have filter bag, and filter bag often according to different use environment for purchase. Of course, in order to better extend the use of filter bags, we should pay special attention to this aspect of knowledge at ordinary times. If we have different problems, we need to find a solution.First, the breakage of the bag. The shape of the filter bag and the installation method and mechanism of the filter bag determine the easily damaged position of the filter bag, so that the inspection and maintenance can be carried out.
Q:Which filter or filter paper has a better filtration effect?
Filter bag filter effect is good, filter bag accuracy range: 0.1-500 microns, the highest filtration efficiency can reach 99.99%. The conventional filtration efficiency is about 95%.
Q:Are there any hot melt nylon filter bags?
Nylon filter bag is generally overedge. Hot melt can also do, nylon material determines the firm as hot-melt seam.
Q:What is the relationship between the life of the filter bag and the dust collector?
When the filter runs under low air volume Q1, at this time Q1 < Q0, so the filter life can be extended to T1, at this time T1 > T0.
Q:What is the cause of the bag explosion in liquid filtration bag?
Impurity scaling is a test of filter materials and workmanship.The use of bag: bag in a strainer is not fixed, with the rotation of the liquid is moving, the bag bag burst and remove the pressure of work as well as the circumstances of the accident, the extent of polishing filter basket also determines the use of filter bag, filtration system design will lead to improper bag burst.
Q:Filter bag welding machine welding process is like this? How to operate it?
The same, intends to link, I specialize in ultrasonic welding machine
