Polypropylene (PP) cotton filter element is an important water treatment and filter product, which has the advantages of good stability and chemical stability. The parameters of polypropylene cotton filter element include several aspects:
1. specifications
Filtration area: generally starting from 1m2 to 16m2, different specifications of polypropylene cotton filter elements use different filter area.
Overall dimensions: determine the external size of polypropylene cotton filter element according to the filter area, filter accuracy and structural design.
Filter accuracy: usually up to 5~150 μ m, divided into different levels.
Foam density: there are mainly polypropylene foam with different densities of 20,30,40,60 and 80 kg / m3.
2. Water force parameters
Flow rate: generally ranging from 2 to 15 m / h, and high-end products can reach 80 m / h.
Pressure drop: rising as the velocity increases.
Permeability: 0.3 ~ 1.2 gpm / psiP, which can vary according to the product model.
Oil and gas filter ability:> 99%, polypropylene cotton filter element has a very good oil and gas barrier ability.
Use flow rate: determined according to the flow rate and filtration area.
3. Filter the component parameters
Filter groove structure: standard, high efficiency and highly efficient different grades.
Filter hole specification: starting from 20 μ m to 0.1 μ m.
Filter material: polypropylene standard filter cotton, high polymer filter cotton, etc.
Material: polymer polypropylene material.
Filtering efficiency:> 99.9%.
4. operational factor
Use temperature: -10~80 C.
Use pressure: 1.0MPa.
Flow rate range: 2~15m / h or even higher.
Pressure drop growth rate: depending on the accumulation of pollutants.
Cleaning cycle: usually from 3 to 6 months.
In conclusion, the parameters of polypropylene cotton filter element mainly include specifications, hydraulic parameters, filter part parameters and operating parameters. Grasping its parameters can help users to choose and use polypropylene cotton filter element.
