The filtration requirements for melt blown filter elements involve multiple aspects, including material properties, filtration accuracy, operating conditions, usage environment, and maintenance and replacement. The following is a detailed analysis of these requirements:


1、 Material characteristics


Raw material selection: Melt blown filter cartridges mainly use non-toxic and odorless materials such as polypropylene (PP), which have good chemical stability and corrosion resistance, and can maintain stable performance in various environments.


Structural features: The melt blown filter element has a deep filtration structure with uniform pore size, sparse outer and dense inner, and loose outer and tight inner. This structure helps to improve filtration efficiency and pollutant holding capacity.


2、 Filtering accuracy


Aperture range: The aperture of the melt blown filter cartridge can be adjusted according to different needs. Common filtration accuracies include 1 μ m, 3 μ m, 5 μ m, 10 μ m, 20 μ m, 30 μ m, 60 μ m, etc. This diverse aperture selection enables the melt blown filter cartridge to be suitable for various filtration requirements.


Filtration efficiency: The filtration efficiency of melt blown filter cartridges is usually between 95% and 99.99%, which can effectively remove small substances such as particles, impurities, bacteria, etc. from liquids or gases. It can filter out particles with diameters between 0.1 and 30 microns, meeting various strict filtration requirements.


3、 Operating conditions


Working temperature: The working temperature of the melt blown filter element is affected by the material properties, generally at 0.25Mpa and not exceeding 70 ℃. In practical applications, it is necessary to ensure that the filter operates within a suitable temperature range to avoid performance degradation or damage.


Pressure and flow rate: The uniform pore size distribution and high porosity of the melt blown filter element result in low resistance, which can meet the requirements of high flow filtration. At the same time, it is also necessary to pay attention to controlling the working pressure and avoid exceeding the bearing range of the filter element.


4、 Usage environment


Medium requirements: The melt blown filter cartridge is suitable for filtering various liquids or gases, but the appropriate filter material and specifications need to be selected according to the specific medium. For example, for highly corrosive media, it is necessary to choose filter materials with good corrosion resistance.


Environmental conditions: During use, it is also necessary to pay attention to the impact of environmental factors such as temperature, humidity, pressure, etc. on the performance of the filter element. Ensure that the filter operates under suitable environmental conditions to extend its service life and maintain good filtration efficiency.


5、 Maintenance and replacement


Cleaning and maintenance: Melt blown filter cartridges can be repeatedly cleaned and reused, but attention should be paid to cleaning methods and maintenance measures to avoid damaging the filter cartridge structure or reducing filtration efficiency.


Replacement cycle: According to the usage and filtration requirements of the filter element, it is necessary to regularly replace the filter element to ensure the filtration effect and service life. The specific replacement cycle needs to be evaluated and determined based on the actual situation.


Above, the filtration requirements for melt blown filter elements cover multiple aspects such as material properties, filtration accuracy, operating conditions, usage environment, and maintenance and replacement. In practical applications, it is necessary to select suitable filter materials and specifications according to specific needs and conditions, and strictly follow operational requirements and maintenance measures for use and management.
