How to judge the quality of liquid filter bag and compare the filtration principle



Filter bag, if it is used for liquid filtration, then can be called liquid filter bag, so as to have a preliminary understanding of the name and know the scope of its application, to avoid the use of error. Moreover, this kind of filter bag is widely used in the filtration of liquid, so a comprehensive understanding is needed in order to achieve the purpose of use through correct and reasonable use.



1. How to judge the quality of the liquid filter bag?


In order to judge the quality of liquid filter bags, it is necessary to look at such technical indicators as filtration efficiency, pore size distribution, density, thickness, weight, permeability and fracture strength of the filter bags. In addition, it can be judged from the following aspects:



Aspect 1: whether the filter bag can be manufactured with materials with good performance and quality, and whether the product can be guaranteed with good performance.


Aspect 2: in the use of the product, can you avoid all kinds of problems, so as not to affect the normal use of the product, whether the use is simple and convenient and has a good effect.


Aspect 3: whether the filter bag is easy to be damaged or damaged in the process of using, because it relates to the cost of using the product.


Aspect 4: filter bag can have a longer service life.



In addition, also need to know that the quality of the liquid filter bag, should be a strong ability to accept pollution, flow, high pressure and easy to operate, and the impurity retention rate and wide range of application, acid and alkali resistance and high temperature resistance, can have a good filtering effect.



2. Is the filtration principle of the liquid filter bag the same as that of the ordinary filter bag?


The filtration principle of the liquid filter bag is relatively simple from a professional point of view. It makes use of the physical or mechanical principle to make the filtrate produce pressure difference. The flowing filtrate passes through the filter bag from inside to outside. Therefore, from its description, we can know that the filtration principle of the liquid filter bag and the ordinary filter bag, there is no difference.



3. Types of liquid filter bag ring mouth and PP liquid filter bag application industry


The liquid filter bag has three kinds of ring mouth: stainless steel ring mouth, PP ring mouth and PE plastic ring mouth, and can be designed with different bag bottom and bag top. PP liquid filter bags, this is a specific type of liquid filter bags, it can be used in food, sewage treatment, chemical, ceramic, pharmaceutical, smelting and manufacturing industries such as filtration operations.
