A Polypropylene (PP) micro-pore folding filter cartridge is a type of water filter constructed from polypropylene, a thermoplastic polymer possessing resistance to chemical corrosion and heat. The foldable design increases the surface area used for filtration which, in turn, enhances its effectiveness.


Its key feature is the micro-pores on the filter surface that effectively trap and eliminate impurities from the fluid passing through. The pores range from 0.1 to 60 micrometers, enabling the filter to remove particulates, such as dust, and microorganisms, like bacteria.


Since polypropylene is resistant to a range of chemicals, these filters are compatible with various fluids, from acidic to basic solutions, making them appropriate for many different industrial applications.


The foldable configuration of the filter increases the filtration area significantly, which allows it to capture a larger volume of impurities before a replacement or cleaning is necessary. This high dirt-holding capacity cuts down the need for frequent maintenance.


Given its construction material, polypropylene filters can resist higher temperatures, making them suitable for filtering hot fluids. Moreover, their d

esign ensures they are physically stable, which leads to consistent performance, lower instances of cartridge collapse and a longer lifespan.


The working principle of a Polypropylene (PP) micro-pore folding filter cartridge is predicated on both overlapping physical properties and the process of filtration.


Constructed from a thermoplastic polymer, the filter cartridge has a unique folded design that effectively enlarges the surface area for filtration. This increased surface area means more fluid can be filtered at a time, enhancing its efficiency.


When water or another type of liquid is channeled into the filter cartridge for purification, it flows into the inner core through the folded filter media. The micro-pores present on the filter surface trap any impurities, contaminants, or particles as the fluid navigates through the filter.


The size of these micro-pores is specific and can range between 0.1 to 60 micrometers. Due to this specific pore size, the filter is capable of removing particulates, bacteria, dust, and other microscopic impurities from the fluid. This process ensures that only clean and purified liquid passes through to the other side.


This filtration process is purely mechanical and does not involve any chemical reactions, making it a safe and effective method for purifying various types of fluids from water to chemicals.


Polypropylene, the fundamental material used to make the filter, is known for its chemical resistance and heat tolerance, qualities that allow for the filtration of both hot and chemically-loaded fluids. The robust and durable nature of the filter ensures that it can consistently provide high performance over an extended service life.


In conclusion, the working principle of a PP micro-pore folding filter cartridge involves the mechanical process of filtration, harnessing the physical properties of a specially designed folded filter media to purify various types of fluids effectively and efficiently.

The PP Micro-Pore folding filter cartridge offers several significant advantages and exhibits unique characteristics which make it useful in a wide array of applications, from home purification systems to industrial-scale filtration processes.
