Ob xyoos dhau los no, tus kab mob tshiab crown tau kis thoob plaws thiab tus kab mob tshiab crown tau kis thoob plaws txawv teb chaws. Peb cov neeg ib txwm yuav tsum tiv thaiv lawv tus kheej kom nruj, ua tib zoo saib xyuas kev hnav lub ntsej muag (lub ntsej muag pov tseg, lub ntsej muag kho mob pov tseg lossisCov qhov ncauj qhov ntswg KN95, N95 lub ntsej muag) thiab ua tib zoo saib xyuas kev sib nrug deb, thiab tsom mus rau cov no. Yog xav paub txog kev tiv thaiv, koj tuaj yeem xa mus rau Tuam Tshoj cov kev coj ua zoo tshaj plaws rau kev tiv thaiv kev sib kis. Ua li no, peb txoj kev noj qab haus huv, suav nrog koj tsev neeg, cov phooj ywg, cov npoj yaig, thiab lwm yam, tuaj yeem nyob deb ntawm tus kab mob thiab txaus siab rau lub neej.
Yog li ntawd, hnub no, ua ke nrog Jin Haocheng, tus neeg tsim khoom ntawmdaim ntaub yaj (cov ntaub npog ntsej muag), cia peb kawm txog seb cov khoom siv ntawmdaim ntaub yajhauv cov qhov ncauj qhov ntswg yog ua.
Cov ntaub yaj cua tshuab feem ntau yog ua los ntawm polypropylene, thiab lub fiber txoj kab uas hla tuaj yeem ncav cuag 1 txog 5 microns. Muaj ntau qhov voids, cov qauv fluffy, thiab muaj peev xwm tiv thaiv kev laus zoo. Cov fibers ultra-fine nrog cov qauv capillary tshwj xeeb nce tus lej thiab thaj chaw ntawm cov fibers ib chav tsev, yog li ntawddaim ntaub yajmuaj kev lim dej zoo, kev tiv thaiv, kev rwb thaiv cua sov thiab kev nqus roj. . Nws tuaj yeem siv rau hauv cov teb ntawm huab cua, cov ntaub ntawv lim dej, cov ntaub ntawv cais tawm, cov ntaub ntawv nqus, cov ntaub ntawv npog ntsej muag, cov ntaub ntawv rwb thaiv cua sov, cov ntaub ntawv nqus roj thiab cov ntaub so.
Txhua tus neeg paub tias cov ntaub npog qhov ncauj kho mob muaj ib txheej ntawmdaim ntaub yajyog li ntawd, cov khoom siv yog dab tsidaim npog qhov ncauj kho mobdaim ntaub yaj ua los ntawm?
Cov ntaub yaj uas siv rau hauv lub npog ntsej muag yog ua los ntawm cov khoom siv polypropylene, thiab cov ntaub yaj kuj yog ua los ntawm cov khoom siv polypropylene hu ua cov fiber ntau-yaj roj. Nws yog ib hom ntaub electrostatic fiber zoo heev, uas tuaj yeem siv hluav taws xob zoo los nqus cov kab mob, hmoov av, thiab cov tee dej, qhov no kuj yog ib qho laj thawj tseem ceeb uas ua rau cov npog ntsej muag tuaj yeem lim cov kab mob. Cov npog ntsej muag kho mob feem ntau siv cov qauv ntau txheej, hu ua SMS qauv: ib txheej spunbond (S) ntawm ob sab. Muaj ib txheej lossis ntau txheej meltblown (M) hauv nruab nrab. Cov khoom siv zoo tshaj plaws rau txheej meltblown yog daim ntaub meltblown. Nws yog cov khoom siv tseem ceeb rau kev lim cov kab mob ntawm lub npog ntsej muag, thiab txheej nruab nrab M-meltblown tsis-woven ntaub. Qhov tseeb, peb txheej no yog cov ntaub tsis-woven, thiab cov khoom siv raw yog polypropylene tag nrho, tab sis cov txheej txheem tsim khoom txawv. Ntawm lawv, txoj kab uas hla ntawm cov txheej spun-bonded ntawm sab hauv thiab sab nraud yog tuab heev, txog li 20 microns; txoj kab uas hla ntawm cov fiber yaj hauv txheej nruab nrab tsuas yog 2 microns, uas yog ua los ntawm cov khoom siv polypropylene hu ua cov fiber ntau-yaj roj. Nws tsis yooj yim tawg thiab tsis tuaj yeem ntxuav nrog dej lossis txau nrog cawv. Txawm tias nws ntub thiab qhuav, nws yuav ua rau cov ntaub so ntswg puas tsuaj thiab ua rau muaj qhov tsis zoo. Yog tias cov kab mob nkag mus rau hauv qhov tsis zoo, lub ntsej muag poob nws lub peev xwm tiv thaiv.
Nrog rau qhov xwm txheej hnyav ntawm qhov xwm txheej sib kis tam sim no, lub ntsej muag tau dhau los ua ib yam khoom tseem ceeb hauv peb lub neej mus ncig. Cia peb nkag siab tias vim li cas lub ntsej muag thiaj li tiv thaiv tau cov kab mob? Ua ntej tshaj plaws, qhov ntim ntawm coronavirus yog 80 ～ 120 nm, vim tias nws feem ntau txuas nrog cov kua dej hauv lub cev thiab txau tawm. , Yog li nws feem ntau loj dua 0.1 um (0.1 micron (um) = 100 nanometers (nm)). Daim ntaub meltblown siv polypropylene ua cov khoom siv raw tseem ceeb, thiab lub fiber txoj kab uas hla tuaj yeem ncav cuag 0.5-10 um. Yog tias nws yog tus kab mob txuas nrog cov kua dej hauv lub cev, nws tuaj yeem lim tawm.
Los ntawm cov lus qhia saum toj no, koj puas paub ntau ntxiv txog cov ntaub npog qhov ncauj?
Rau kev paub txog kev tshaj lij thiab kev sab laj txogCov ntaub tsis-woven yaj, Cov Khoom Uas Tsis Yog Woven Tiav Lawm, Cov Ntaub Tsis-woven Spunlace, Lim Cov Ntaub Tsis-woven, Cov ntaub tsis yog woven uas muaj koob xuas, koj tuaj yeem tiv tauj Jin Haocheng Non-woven Fabric. Peb yuav ua qhov zoo tshaj plaws los pab koj.
