What is PP Melt Blown Filter Cartridge And Its Features?

PP melt blown filter cartridge plays an important role in the pre-filtration system of RO filter, which is used to block the rust, sand and other large particles in the water.  Let's discuss:

1. What is PP melt blown filter cartridge?

PP melt blown filter cartridge is use of non-toxic and odorless polypropylene, after heating melting, spinning, traction to form tubular filter cartridge. 

2.What are PP melt blown filter cartridge features? 

1. Water flows from outside into inside, through multi layers of filtration, the closer to the inner layer of the filter cartridge, the smaller aperture, the higher filtration accuracy. Particle impurities are passing through PP melt blown filter cartridge pore channel, particles can be blocked at channel, then removing various pore size particles.

2. PP melt blown filter cartridge structure is that the tighter inner layer and the looser outer layer structure. Its performance is characterized by the outer layer of relatively thick fiber, the inner layer of relatively fine fiber. This structure can achieve each layer abble to interception of sediment and other impurities in water, layer by layer, to realize large contaminant capacity.

3. Its raw polypropylene relies on self-bonding to tangle with each other to form a three-dimensional curved microporous structure, which is different from traditional fabrics fiber distribution and has a larger surface area, higher porosity, allowing water to pass through quickly, large filtration area, small pressure difference.

4. Does not contain chemical adhesives, more hygienic. Unlike other filter cartridges,  PP melt blown filter cartridge does not need to be bonded with other materials. Its self chemical composition is clean, there will be not secondary pollutiondue to the material, safety use.

5. Its raw material is polypropylene, which has good chemical stability and low cost.
