PTFE sintered filter element, also known as polytetrafluoroethylene (PTFE) sintered filter element, is made of pure PTFE raw material sintered at high temperature and high pressure, and has various excellent filtration performance and wide application fields. The analysis of its filtering level can be carried out from the following aspects:


1、 Filtering accuracy


The filtration accuracy of PTFE sintered filter element is one of its core performance indicators. According to different production processes and customer needs, the filtration accuracy of PTFE sintered filter cartridges can reach different levels, usually including the following ranges:


High precision filtration: such as 0.1 microns, 0.3 microns, 0.45 microns, etc. These high-precision filters are particularly suitable for applications that require high-purity liquids, such as pharmaceuticals, electronics, semiconductors, and other industries.


Medium precision filtration: such as 1 micron, 3 microns, 5 microns, etc. These filter cartridges are suitable for filtering general industrial liquids and can effectively remove impurities such as suspended solids and particulate matter.


Low precision filtration: such as 10 microns, 20 microns, etc. These filter cartridges are mainly used for coarse filtration, which can remove larger particles and impurities and protect subsequent filtration equipment.


2、 Filtration efficiency


The filtration efficiency of PTFE sintered filter mainly depends on its porosity, pore size distribution, and filter structure. Due to its high porosity and uniform pore size distribution, the PTFE sintered filter element has a high filtration efficiency, which can maintain a large fluid flow rate while ensuring filtration accuracy. In addition, the smooth outer surface of the PTFE sintered filter element is also conducive to the rapid removal of impurities, improving the filtration efficiency.


3、 Filter performance stability


The PTFE sintered filter element has extremely high chemical and thermal stability due to its special material properties. Therefore, in various corrosive liquids and high-temperature environments, PTFE sintered filter cartridges can maintain stable filtration performance and are not easily corroded or damaged. This stability enables the PTFE sintered filter element to exhibit excellent filtration performance under various harsh working conditions.


4、 Application Fields


The filtration grade and performance characteristics of PTFE sintered filter cartridges determine their wide range of application fields. Here are some of the main application areas:


Pharmaceutical industry: used for filtering antibiotic fermentation broth, injection solution, oral solution, etc., to ensure the purity and safety of drugs.


Chemical industry: used for filtering various corrosive liquids, such as acidic and alkaline solutions, organic solvents, etc., to protect the quality of subsequent equipment and products.


Electronics industry: used in high-precision filtration applications such as ultrapure water preparation and semiconductor manufacturing to ensure the stability of the production process and product quality.


Food and beverage industry: It is used for filtering syrup, beverage, Baijiu and other liquids to improve the taste and quality of products.


Environmental protection industry: used in wastewater treatment, air purification and other fields to remove pollutants and purify the environment.


The filtration grade of PTFE sintered filter cartridge varies according to different production processes and customer needs, but overall it has the advantages of high precision, high efficiency, and good stability, and has been widely used in multiple industries.
