Polypropylene dust detection filter membrane 0.8u

Polypropylene dust detection filter membrane diameter25mm 30mm 35mm 37mm 40mm 75mm aperture0.8U

Polypropylene filter membrane can be used for dust detection‌Especially suitable for collecting total dust and exhaled dustIt has the advantages of strong electrostatic adsorption, low moisture absorption, and low ventilation resistance, but it should be noted that it is not resistant to high temperatures and cannot be used for dust dispersion detection

‌Dust measurement characteristics of polypropylene filter membrane

Polypropylene filter membrane is widely used in atmospheric environment sampling and occupational health testing for dust (such as...)PM2.5The collection of total dust and exhaled dust has strong electrostatic characteristics that can effectively adsorb particulate matter, and has high mechanical strength, making it suitable for long-term sampling

Electrostatic adsorption‌Smooth surface, easy to peel off dust, convenient for cleaning.‌‌

‌Low hygroscopicity‌Stable performance in dry and wet environments.‌‌

‌Low ventilation resistance‌Suitable for use with high flow samplers

局限性

Not resistant to high temperatures‌May deform or fail in high temperature environments.‌‌

‌Dispersion detection limit‌Unable to conduct dust dispersion analysis through dissolution like vinyl chloride filter membrane
