Liquid Filter Bag Permeability Of The Material
Aug 30, 2017

Liquid Filter Bag Permeability of the material

What is the reason why the life of the liquid filter bag is short

To know the service life of the filter material and the permeability of the material are inextricably linked, the material permeability is low, the filter bag using the original pressure difference is small, slow pressure, natural filter bag life is long, and vice versa in contrast. In addition to the surface treatment process control is also good or bad impact on the life of the filter bag. Liquid mat is the surface of the strict singeing process, if the pursuit of surface finish, there have been burning the molten fiber will plug the filter channel, will naturally reduce the permeability of the liquid to improve the pressure drop of the filter, and ultimately reduce the filter bag Of the service life.

Liquid filter bag bonding technology

Hot melt

The use of advanced hot-melt bonding technology to ensure that the filter bag has the best bonding strength, to prevent leakage.

2. Sewing

Sewing rigorous, solid and durable, the joints will be sealed to the ultimate effect. Pure car suture does not contain any silicone oil and other lubricant ingredients, to avoid the ordinary sewing bag bag secondary pollution and other issues. Liquid filter bag filtrate filter surface are special singeing treatment, both effective to prevent the fiber from the pollution of the filtrate, but also to avoid the traditional roller processing caused by excessive clogging filter hole and shorten the bag life. All the raw materials are white, without any special bleaching and dyeing treatment, in full compliance with environmental standards, but also because of the three-dimensional filter layer of needle felt, so that the liquid flow through the filter bag, the particles will be due to deep filtration mechanism retained in the liquid filter bag wall Surface and deep, with high capture efficiency for solid or colloidal particles. Acupuncture felt thickness uniformity, stable perforation rate and sufficient strength to filter bag efficiency and stability, the use of longer time. Five-wire double needle the most tight sewing, to ensure that each liquid filter bag to achieve the best filter protection. Wide range of applications for liquid filtration in all industries.


1, the use of silicone oil-free high-speed industrial sewing machine production, will not produce silicone oil pollution problems.

2, the mouth of the suture after the improvement is not very high protrusions caused by the side of the leakage did not lead to eye leakage phenomenon.

3, the filter bag marked on the product specifications of the label all selected easy to take off the way to prevent the use of the filter bag and ink on the filter contamination.

4, the filter accuracy range from 0.5 microns to 300 microns, the material is divided into polyester, polypropylene filter bag.

5, stainless steel and galvanized steel ring argon arc welding technology. Diameter error is only less than 0.5mm, the level of error is less than 0.2mm, the use of this ring made of filter bag installed in the device can improve the degree of sealing, reduce the risk of side leakage.
