Introduction to PP for Household Water Filter Cartridges
PP is mainly used in domestic water filtration systems, such as Water Filter Cartridges(KOKOELECTRIC) for RO systems. 100% food grade polypropylene (PP) is used as the material, and the filter cartridge contains no wetting agent, solvent, antistatic agent or binder. The removal efficiency can reach 98%.
The surface layer of the filter cartridge is designed to be low density to ensure high dust holding capacity, while the inner layer is denser to maintain precise filtration of small particles. The density type is 30% higher than the general type of filtering.
What kind of PP is a water filter cartridges for high quality domestic water filtration systems?
PP is a tight outer layer and multilayer structure.
Why are some PP cotton surfaces very hard?
In order to reduce the cost, some enterprises add a large amount of calcium carbonate to the PP material. After the calcium carbonate is added, the PP cotton is melted and sprayed and hardened, resulting in a significant decrease in the dust holding capacity of the PP. cotton.
What factors can determine the quality of PP cotton?
The heavier the better. The higher the fiber density, the better the compressibility and the better the pp.
Many domestic water filtration systems have pp filters, most of which are pp10. Usually, pp is placed better before the activated carbon filter.
