As one element of the filters, filter bag is a key part in the filtration process. In fact, the quality of the filter bag decides the filtering effect to a great extent. The materials for making filter bag include nylon, polypropylene, polyester, stainless steel and polytetrafluoroethylene.
Basically, there are many kinds of filter bags, such as liquid filter bag, air filter bag and so on. In specific, we will firstly talk about the liquid filter bag.
The ring of the liquid filter bag can be stainless steel, polypropylene and polyethylene plastics. The design of liquid filter bag includes all sorts of different bag bottoms and bag tops. The filter-out surface of it is processed by special singeing. This not only prevent the fiber from falling off and pollute the filtrate, and also avoid tradition al roll-in technology to jam the filtration bore and reduce the service life.
Furthermore, all the materials are raw white without any special bleaching process. The stable open hole ratio and sufficient strength ensure steady filtration efficiency and long operate time. Also, the liquid filter bag can provide the best filtration security. With the wide range of application, it is applied to the liquid filtration in all industries.
The filter bag has high collection efficiency for solid or colloidal particles. After special treatment, it can effectively prevent the fiber from getting out of the contaminated filtrate. The special double-needle sewing process ensures better filtration protection for each liquid filter bag. It is suitable for liquid filtration in various industries.
