Puas yog Tsis yog -Woven Fabric tsim nyog rau Kev Ua Qhov Ncauj?

Tsis yog- ntaub npuag yog cov khoom tseem ceeb hauv kev tsim daim npog ntsej muag, muab qhov sib npaug ntawm kev tiv thaiv, ua pa, thiab tus nqi- ua tau zoo. Txawm li cas los xij, nws qhov kev ua tau zoo tshwj xeeb nyob ntawm cov khoom sib xyaw thiab cov txheej txheem tsim khoom.

Lub peev xwm tiv thaiv tsis yog- cov npog ntsej muag feem ntau yog los ntawm lawv cov qauv fiber ntau. Cov randomly faib cov fibers tsim ib lub network ntom ntom uas cuam tshuam cov tee dej, plua plav, thiab lwm yam khoom, thaum tus qauv ntxeem tau ua kom ua pa zoo. Cov khoom siv polypropylene (PP) feem ntau yog hydrophobic, zoo tiv thaiv cov kua txau, thiab yog lub teeb yuag thiab mos, ua rau lawv haum rau hnav ntev. Cov qhov ncauj qhov ntswg kho mob feem ntau txais yuav peb - txheej txheej: txheej txheej ntawm spunbond uas tsis yog - woven npuag rau waterproofing thiab plua plav; ib txheej nruab nrab ntawm yaj- tshuab tsis yog- ntaub ntaub uas siv electrostatic adsorption los ntes cov khoom me me (xws li cov kab mob); thiab ib txheej txheej ntawm daim tawv nqaij -cov ntaub spunbond tus phooj ywg los txo cov tawv nqaij khaus. Qhov "sandwich" tsim no sib npaug tiv thaiv thiab kev nplij siab. Piv txwv li, cov kab mob pom kev ua haujlwm ntawm lub ntsej muag phais feem ntau tshaj 95%.

Piv rau paj rwb lossis knitted npuag qhov ncauj qhov ntswg, tsis yog -cov npog ntsej muag pom pom kev ua haujlwm zoo dua. Cov ntsej muag paj rwb zoo ib txwm tso siab rau ntau txheej ntawm cov ntaub, muab kev tiv thaiv tsis pub muaj PM2.5 lossis cov kab mob, thiab feem ntau muaj kev ua pa tsis zoo. Knitted npuag qhov ncauj qhov ntswg muaj qhov sib txawv loj ntawm cov fibers, ua rau lawv tsim nyog rau kev tiv thaiv plua plav ntau dua li kev tiv thaiv microbial. Txawm li cas los xij, cov npog ntsej muag uas tsis yog- feem ntau yog tsim los siv ib zaug, thaum lub ntsej muag paj rwb thiab knitted tuaj yeem ntxuav thiab rov siv dua. Nws yog ib qho tsim nyog sau cia tias KN95/N95 qhov ncauj qhov ntswg, uas tseem siv tsis yog- ntaub npuag, ua kom pom kev ua tau zoo ntawm ntau dua 95% los ntawm ntau txheej txheej ntawm cov yaj{11}} tshuab tshuab thiab kho electrostatic kho kom zoo, ua rau lawv haum rau siab - ib puag ncig kev pheej hmoo.

Txawm hais tias lawv qhov zoo, tsis yog -cov npog ntsej muag muaj qee qhov kev txwv:

- Thaum tshav kub kub rhiab heev:Cov ntaub ntawv polypropylene ntsws los yog deform ntawm qhov kub siab tshaj 80 degree, ua rau lawv tsis tsim nyog rau kev ua kom tsis muaj menyuam.

- Electrostatic lwj:Cov nyhuv electrostatic adsorption ntawm yaj- txheej txheej tshuab ploj zuj zus thaum lub sijhawm lossis nrog cov av noo ntau ntxiv. Nws raug pom zoo kom khaws lub qhov ncauj qhov ntswg tsis pub ntau tshaj ob xyoos.

- Kev txhawj xeeb txog ib puag ncig:Polypropylene yog qhov nyuaj rau degrade, thiab muab pov tseg lub qhov ncauj qhov ntswg yuav tsum tau muab pov tseg kom tsis txhob muaj kuab paug ib puag ncig.

Kev xaiv thiab kev pom zoo siv

1. Tshawb xyuas cov qauv:High-quality masks should have three distinct layers-a stiff, waterproof outer layer, a dense middle layer, and a soft inner layer. Ib txoj kev sim yooj yim: txiav qhib lub npog ntsej muag; qhov nruab nrab yaj- txheej tshuab tshuab yuav tsum nthuav tawm electrostatic adsorption (xws li, nyiam daim ntawv me me thaum rub tawm).

2. Tsis txhob rov siv dua:Cov khoom siv pov tseg uas tsis yog- cov npog ntsej muag yuav tsum tau hloov tom qab 4-6 teev ntawm kev siv lossis thaum lawv ntub los yog muaj kab mob. Lawv yuav tsum tsis txhob ntxuav los yog tshuaj tua kab mob nrog cawv.

Vim nws qhov kev ua tau zoo ntawm kev pom zoo thiab cov yam ntxwv ntawm lub teeb, lub ntsej muag tsis yog -woven tau dhau los ua thawj qhov kev xaiv rau kev tiv thaiv kev kho mob thiab kev tiv thaiv kev sib kis txhua hnub. Nws qhov txiaj ntsig tseem ceeb yog nyob rau hauv cov nyhuv electrostatic adsorption ntawm yaj- txheej tshuab, tab sis yuav tsum tau them nyiaj rau qhov kev txwv ntawm ib zaug - siv. Rau cov tib neeg zoo tib yam, lub npog ntsej muag kho mob tuaj yeem ua tau raws li qhov xav tau kev tiv thaiv txhua hnub, thiab cov haujlwm tshwj xeeb lossis siab - cov xwm txheej yuav tsum tau xaiv KN95 / N95- cov khoom qib. Nyob rau hauv lub neej yav tom ntej, nrog rau kev nce qib ntawm cov cuab yeej technology, non-woven lub qhov ncauj qhov ntswg nrog ntxiv nanofibers, biodegradable cov ntaub ntawv, los yog PTFE membranes yuav ntxiv txhim kho lawv kev tiv thaiv thiab ib puag ncig kev ua tau zoo.
