Kev paub ntawm cov ntawv lim

Kev tshawb fawb ntawm cov ntawv pov thawj muaj peev xwm muab faib ua ob yam, ib qho yog cov cwj pwm lim cov ntaub lim dej, ntawm qhov tod tes yog cov yam ntxwv ntawm lub cev. Cov yam ntxwv pom muaj xws li cua permeability, roj ua haujlwm, qhov siab tshaj plaws, aperture nruab nrab. Cov cwj pwm ntawm lub cev muaj xws li: ntau npaum, tuab, nruj, corrugated qhov tob, rhuav tshem cov degree, cov ntawv nyeem, etc.

Quantification: Hais txog qhov zoo ntawm daim ntawv lim ib lub xwm fab xwm meem, chav tsev: g / m ².

Thickness: Hais txog qhov tuab ntawm daim ntawv lim, tsis suav qhov tob. Unit: MM.

Cov Kuj Muaj Kev Tiv Thaiv: Cov tsis ua haujlwm ntawm cov ntawv lim dej rau huab cua. Daim ntawv lim dej 100CM2 siv los sawv cev rau qhov siab poob nqis ntawm 85 liters ntawm cov huab cua hauv ib feeb. Chav tsev yog mbar. Los yog qhov siab ntawm cov dej kem (hli).

Corrugated qhov tob: Ua kom muaj kev sib zog ntawm txoj hlab ntsug ntawm kev lim ntawv thiab ua rau lub qhov tob tob ntxiv, Chav tsev yog: MM. Nyob rau hauv dav dav, nws muaj nqis yog 0.2 hli.

Permeability: Hauv ib cheeb tsam, hauv qee qhov siab (20 hli dej sab), ib zaug twg los ntawm cua ntim ntawm daim ntawv lim. Chav nyob yog: L / m2 ·

Nominal filtration tseeb: hais txog qhov peev xwm ntawm lim ntawv mus rau tuav ntawm ib qhov me me, yuav khaws cia los sis lim tawm ntawm 50% ntawm ib qho me me ntawm particle loj. Chav: μ M.

Max aperture: Qhov void me xam thaum thawj npuas tawg nyob rau hauv tsab ntawv lim dej yog kuaj. Chav: μ M.

Txhais tau qhov tseeb: Lub aperture ntawm lub siab xam nrog "ntom" bubbling yog hu ua qhov nruab nrab lub ntsiab lus. Chav tsev yog: M.

Cov ntsiab lus teb: Cov tshuaj khib nyiab txhawm rau qhov feem pua ​​ntawm cov ntawv ceeb toom. Feem ntau 10% ~ 30%

Kev mob taub hau: kev muaj peev xwm los tiv thaiv kev lag luam ntawm daim ntawv lim. Chav: MG.

Rhuav degree: Qhov siab tshaj plaws uas muaj peev xwm tiv tau lub cheeb tsam ntawm cov ntawv lim. Chav: kpa.
