Cov khoom muaj fiber ntau thiab cov yam ntxwv ntawm cov khoom
Lub tuab ntawm cov nanofibers tsuas yog ib txhiab ntawm tib neeg cov plaub hau. Lub tuab ntawm lub npog ntsej muag tub ntxhais txheej ua los ntawm cov nanofibers tsis ntau tshaj 3 microns, thiab kev ntsuas qhov tseeb yog tsawg dua 0.1 microns. Lub nanofibers tuaj yeem cuam tshuam txog cov mob tee, PM2.5, cov kab mob thiab kab mob, thiab muaj cov roj tsis ua haujlwm rau lub cev fil96%. Cov cua zoo permeability thiab ua pa du (nqus tau yog ib feem peb ntawm cov pa ntawm cov pa pa N95).
Kev ua haujlwm ruaj khov, rov siv tau: Nanofiber membrane tsuas yog cia siab rau kev ua haujlwm ntawm lub cev, tuaj yeem lim cov kab mob thiab kab mob yuav luag 100%; Tom qab kho nrog cawv, qhov pom ntawm kev ua haujlwm rau cov tsis muaj roj yog 89% ~ 93%. Tom qab raug kho nrog dej npau npau, kev ua haujlwm ntawm cov roj tsis huv yog 90% ~ 93%, qhov kev tiv thaiv muaj kev tiv thaiv tau zoo, thiab tuaj yeem rov qab siv tsawg kawg yog 3 zaug, uas yog yig.
Siv tshuab thev naus laus zis
Daim Ntawv Thov: Lub tshuab hluav taws xob electrostatic spinning nanometer polyacrylonitrile fiber ntau tuaj yeem txiav raws li qhov yuav tsum tau ua, tom qab txiav, nws tuaj yeem siv rau cov hom phiaj tshwj xeeb, xws li daim npog qhov ncauj, cov khoom lim dej.
Daim ntawv thov fiber ntau
Q:
Dab tsi yog cov yam ntxwv ntawm lub npog ntsej muag tseem ceeb npaj los ntawm electrostatic spinning polyacrylonitrile nanofiber membrane?
A:
Raws li electrostatic spinning technology, cov khoom siv ntws-pab tau ntau yam khoom siv rau electrostatic spinning tau tsim nrog cov cuab yeej kev txawj ntse txoj cai. Polyacrylonitrile nanofibers uas ua los ntawm cov khoom siv no tuaj yeem txo cov kab ntsig fiber ntau los ntawm 2-3 zaug piv nrog cov tshuab hluav taws xob spinning, thiab cov kev ua haujlwm siab dua. Tom qab ntawd, polyacrylonitrile nanofiber membrane tau nrog cov tshuaj melt-tshuaj tsuag tsis-ntaub daim ntaub los tsim lub siab ua haujlwm thiab tsis tshua muaj qhov npog qhov ncauj qhov ntxaij lim dej nrog cov qauv gradient, uas tuaj yeem txo qhov kev tiv thaiv kev ua pa thiab ua kom muaj kev nplij siab thaum paub tseeb tias qhov raug thiab siv tau. Lub hauv paus lim yog cuam tshuam tag nrho ntawm lub cev adsorption thiab cuam tshuam, thiab tsis dhau los ntawm cov ncej ruaj ruaj. Yog li ntawd, nws txoj kev tiv thaiv tsis tshua muaj kev cuam tshuam los ntawm kev txau cawv, dej thiab av noo. Nws tuaj yeem rov qab siv dua li ntawm peb zaug, uas yog kev yig.
