1, Core technology of precision filter bottle: 5-micron PP cotton filter medium
As an important equipment in modern water treatment technology, the core of precision filter bottles lies in the selection and design of filter media. 5-micron PP cotton (polypropylene fiber cotton) is an ideal material for filtering particulate matter, floating particles, and fine particles in water due to its unique physical and chemical properties.
The physical structure of PP cotton
PP cotton is made by melt spraying process, with fine fiber diameter and three-dimensional network distribution, forming a multi-layer gradient filtration structure. A 5-micron aperture design can effectively intercept impurities with a diameter greater than 5 microns (such as sediment, rust, colloids, etc.), while allowing water molecules and small mineral particles to pass through, balancing filtration accuracy and water flow rate.
Chemical stability and safety
Polypropylene, as a food grade material, is acid and alkali resistant, non-toxic, and will not release harmful substances after long-term use. Its hydrophobic characteristics can also inhibit bacterial growth and avoid secondary pollution.
Multi layer composite filtration mechanism
Precision filter bottles usually adopt a multi-layer PP cotton structure with "outer sparse and inner dense": the outer fibers are loose, intercepting large particles; The inner fibers are tightly packed, adsorbing fine suspended solids. This design significantly extends the lifespan of the filter element and reduces the risk of clogging.
Adopting top-grade, food-grade PP cotton, our filter efficiently screens out major impurities like sand, colloids, and suspended particles, safeguarding the functionality of subsequent filter elements. It is an ideal addition to sophisticated water treatment technologies, encompassing precision filtration sentinels and RO reverse osmosis pure water producers.
Utilizing premium food-grade PP cotton, this filter efficiently removes sediment, colloids, and suspended impurities from water, ensuring optimal protection for subsequent filters. It is compatible with advanced water processing equipment, including precision filtration guards and RO reverse osmosis pure water machines.
- PP cotton has a fine fiber structure that can effectively trap impurities such as dust, sediment, and particulate matter. In water filtration systems, it can remove suspended solids and improve water clarity. For example, in household water purifiers, PP cotton filters are often the first stage of filtration to protect downstream filters and ensure clean drinking water.
