Vim tias tus kab mob Coronavirus tshiab no tab tom kis mus thoob plaws,lub ntsej muag npog ntsej muagtau dhau los ua ib yam khoom siv tiv thaiv tseem ceeb rau tib neeg. Tam sim ntawd, lub ntsej muag lub ntsej muag tau dhau los ua khoom muag tsis tshua muaj nyob hauv khw. Thiab kev tsim cov ntsej muag lub ntsej muag ntawm cov khoom siv raw meltblown nonwoven fabrics, vim qhov sib txawv loj dhau, hauv lub network tau dhau los ua qhov kub, tab sis kuj yog qhov nyuaj.
Ua ntej muaj tus kab mob sib kis, muaj tsawg tus neeg paub txog nws. Tom qab muaj tus kab mob sib kis, lawv paub tias nws yog ib yam khoom tshwj xeeb rau kev tsim cov ntaub npog qhov ncauj.
Cov thev naus laus zis ntawm meltblown nonwoven yog dab tsi?
Cov hauv qab no yog raws li nram noyaj-blown nonwoventus neeg tsim khoom ntaub kom nkag siab:
Txoj kev tsuag yaj: daim ntaub lim dej polypropylene fiber zoo heev, vim nws nyob hauv kev lag luam textile, yog daim ntaub tsis-woven, cov txheej txheem yog txoj kev tsuag yaj, lub npe dav dav: daim ntaub tsuag yaj tsis-woven.
Muaj ntau hom ntaub meltblown uas siv tau dav. Cov ntaub melt-spray uas siv rau hauv kev tsim cov ntaub npog ntsej muag yog cov ntaub lim polypropylene fiber zoo heev uas tau hais los saum toj no, uas ua tau raws li qhov yuav tsum tau ua ntawm cov ntaub npog ntsej muag.
Yog li dab tsi yog qhov yuav tsum tau ua rau cov ntaub meltblown nonwoven siv ua lub npog ntsej muag?
1. Khoom siv: ua raws li tus qauv kev huv;
2. Kev nkag tau huab cua (kev ua haujlwm kis tau zoo): tshaj 95%;
3. Kev tiv thaiv: hauv qab 40Pa;
4. Cov khoom siv hydrophobicity zoo.
Yog li ntawd, cov lus qhia txog kev siv cov ntaub lim dej polypropylene fiber ntau ua tau raws li qhov yuav tsum tau ua ntawm cov ntaub npog qhov ncauj. Yog tias lub ntaub npog qhov ncauj yog ua los ntawm cov ntaub tsis-woven uas yaj-tshuaj tsuag ib leeg, nws tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua zoo.
Vim li cas thiaj yuav tsum ua lub npog ntsej muag nrog "melt spray ultrafine polypropylene fiber filter cloth"?
Vim tias, nce mus los ntawm cov khoom zoo, qhov ntsuas tseem ceeb ntawm polypropylene fiber, yam ntxwv nws ua tau raws li tus qauv zoo, avirulent, tasteless, dej tsis zoo yog qhov zoo tos rau tus yam ntxwv.
Los ntawm cov txheej txheem ntau lawm, txoj kev siv tshuaj tsuag yaj tau txais yuav, vim tias cov dej ntws ntawm cov txheej txheem tsuag yaj: feem ntau yog los ntawm: yaj - dav hlau - cua ntsawj ntshab kom ncav cuag qib ntawm cov fiber ntau ultrafine, thiab cov ntaub woven yog tsim los ntawm nws tus kheej cua sov, yog li cov huab cua zoo permeability thiab kev ua haujlwm siab lim dej. Lwm cov txheej txheem ntau lawm nyuaj rau ua tiav.
Qhov saum toj no yog ib qho kev qhia luv luv ntawmcov ntaub tsis-woven uas yaj tawmVam tias koj yuav nyiam nws. Peb yog cov chaw tsim khoom ntawm cov ntaub meltblown nonwoven.Yog tias koj xav tau yuav khoom, thov hu rau peb tam sim ntawd. Tsis txhob yig ~ peb tuaj yeem xa cov qauv rau koj dawb ~
