How to increase the service life of PP filter bag?
In industrial water treatment and filtration processes, pp filter bags are often used with bag filters to achieve better filtration results. Filter bags are made of polypropylene, whose production process includes hot melt and joint, widely used in petrochemical, natural gas, paint, ink, medicine, bioengineering, automotive manufacturing, electronics, electroplating, food, beverage and other fields. So, what do you know about the life ofliquid filter bags? Next, let’s look at the introduction in this article. (Shanghai Liquid filter bag manufacturer)
So, how to increase the service life of filter bag? The following measures can be taken:
1, the selection of suitable filter material,pp liquid filter bagselection filter material should be based on the temperature of the gas, chemical characteristics, filtration speed, cleaning method, emission concentration and bag dust collector work system, etc.
2, the structure of the design of reasonable structure of liquid filter bag should meet the requirements of the matching bag dust collector filtering and cleaning, and convenient installation, reliable sealing.
3 sewing technology, exquisite sewing size should comply with the design requirements, and according to the varieties of filter material and the use of temperature, the reserved heat shrinkable size, reasonable suture needle distance, suture in conformity with the requirements, no burr or fracture and damage of pp filter bag, do not damage during storage and transportation on the way or be affected with damp be affected with damp, should not be weighed and shelf life is too long, otherwise will affect the service life.

4, the correct use method and preservation method. When using pp liquid filter bag for filtration, it is necessary to ensure that the inlet water quality is within the reasonable bearing range of the filter bag aperture. Liquid filter bags should be cleaned regularly. At the time of purchase, the liquid filter bag with larger demand than the actual water production can be selected to reduce the water production load of the filter bag.
PP liquid filter bag is made of polypropylene fiber material, accuracy range of 0.1-500μm, can be used for coarse, medium and fine filtration, has good heat resistance. The normal service life of the product is 6-12 months, and the specific use is determined by the filtered water quality. If the water yield of the filter bag is stable, the water quality is good, and the filter bag is not damaged, it can be recycled all the time. After cleaning, the filtration function of pp filter bag will be worse than when just used. This is normal. If the water quality of the liquid filter bag changes greatly after cleaning, it may indicate that the filter bag is damaged and the aperture has changed. At this point, the liquid filter bag needs to be replaced. In addition, the hydrophilicity of liquid filter bags should be checked before using bags that have not been used for a long time.
