Raws li Jiangsu Provincial Market Supervision Administration lub vev xaib, thaum Lub Plaub Hlis 23, Jiangsu Textile Industry Association tau tshaj tawm cov txheej txheem "Polypropylene Melt blown Nonwoven Fabrics for Masks" (T/JSFZXH001-2020), uas yuav raug tso tawm rau lub Plaub Hlis 26. Kev nqis tes ua.
Tus txheej txheem tau npaj los ntawm Jiangsu Fiber Inspection Bureau nyob rau hauv kev taw qhia ntawm Jiangsu Market Supervision Bureau, thiab tsim ua ke nrog Nanjing Khoom Zoo Saib Xyuas thiab Tshuaj Xyuas Lub Tsev Haujlwm thiab cov tuam txhab tsim cov ntaub npuag. Cov qauv no yog thawj lub teb chaws tus qauv muab rau daim npog ntsej muag-tshuab yaj cov ntaub. Nws yog tsuas yog siv tau rau daim npog ntsej muag-tshuab cua tshuab rau kev tiv thaiv kev huv. Nws tau txais los ntawm cov tswv cuab hauv pab pawg raws li kev pom zoo thiab tau txais kev pom zoo los ntawm cov zej zog. Kev tshaj tawm thiab kev ua raws li tus qauv yuav ua lub luag haujlwm tseem ceeb hauv kev tswj hwm kev tsim khoom thiab kev ua haujlwm ntawm cov khoom lag luam yaj-tshuab thiab ua kom ntseeg tau qhov zoo ntawm cov khoom siv raw ntawm lub qhov ncauj qhov ntswg. Nws tau nkag siab tias cov txheej txheem pab pawg xa mus rau cov qauv sib koom ua ke los ntawm cov pab pawg sib raug zoo tsim raws li txoj cai kom ua tau raws li kev ua lag luam thiab kev tsim kho tshiab thiab koom tes nrog cov neeg ua lag luam cuam tshuam.
Melt blown daim ntaub muaj cov yam ntxwv ntawm me pore loj, siab porosity thiab siab pom efficiency. Raws li cov khoom siv tseem ceeb rau kev tsim daim npog ntsej muag, qhov kev thov tam sim no ntau dua li cov khoom siv. Tsis ntev los no, cov tuam txhab muaj feem cuam tshuam tau hloov mus rau yaj cov ntaub npuag, tab sis lawv tsis muaj kev paub txaus txog cov khoom siv raw, khoom siv, thiab cov txheej txheem tsim khoom siv. Kev ua tau zoo ntawm cov ntaub nplaum yaj yog tsis siab, thiab qhov zoo tsis tuaj yeem ua tau raws li qhov xav tau ntawm kev tsim daim npog ntsej muag.
Tam sim no, muaj ob txoj kev lag luam tsim nyog rau cov khoom siv yaj hauv Suav teb, uas yog "Spun bond / Melt blown / Spun bond (SMS) Method Nonwovens" (FZ / T 64034-2014) thiab "Melt blown Nonwovens" (FZ / T 64078-2019). Cov qub yog tsim rau cov khoom siv SMS uas siv polypropylene los ua cov khoom siv tseem ceeb thiab ntxiv dag zog los ntawm kev sib koom ua ke ntawm kub dov; tom kawg yog tsim rau cov ntaub tsis-woven uas tsim los ntawm txoj kev yaj-tshuab. Kev siv kawg tsis txwv rau lub qhov ncauj qhov ntswg, thiab tus qauv tsuas yog rau qhov dav, qhov loj ntawm ib chav tsev, thiab lwm yam. Txhawm rau muab cov kev xav tau, cov qauv ntsuas qhov tseem ceeb xws li pom kev ua haujlwm zoo thiab huab cua permeability tau teev tseg los ntawm cov khoom siv thiab xav tau daim ntawv cog lus. Tam sim no, kev tsim cov tshuab ziab khaub ncaws los ntawm cov tuam txhab lag luam feem ntau yog raws li cov qauv kev lag luam, tab sis cov ntsuas cuam tshuam kuj tsis sib xws.
Cov pab pawg txheej txheem ntawm "Polypropylene Melt blown Nonwoven Fabrics for Masks" tso tawm lub sijhawm no yog nyob ib puag ncig polypropylene yaj cov tshuab tsis woven rau lub qhov ncauj qhov ntswg, qhia cov khoom siv raw, kev faib khoom, cov kev cai yooj yim, cov kev cai tshwj xeeb, kev tshuaj xyuas thiab kev txiav txim, thiab cov khoom logo teev cov kev cai kom meej. Cov kev qhia tseem ceeb ntawm pab pawg qauv suav nrog kev lim dej ua kom zoo, cov kab mob lim dej ua kom zoo, tawg lub zog, qhov sib txawv loj ntawm ib cheeb tsam, thiab cov kev xav tau zoo. Tus txheej txheem teev tseg cov hauv qab no: Ua ntej, cov khoom raug cais raws li kev pom kev ua haujlwm ntawm cov khoom, uas tau muab faib ua 6 qib: KN 30, KN 60, KN 80, KN 90, KN 95, thiab KN 100. Qhov thib ob yog los qhia cov ntaub ntawv raw siv, uas yuav tsum tau raws li qhov yuav tsum tau ntawm "Tshwj xeeb yas Melt-Blowing Material rau PP" (GB / T 30923-2014), txwv tsis pub siv tshuaj lom thiab phom sij. Qhov thib peb yog txhawm rau muab cov kev cai tshwj xeeb rau kev ua kom pom kev ua kom pom tseeb thiab cov kab mob pom kev ua haujlwm zoo sib xws rau qib sib txawv pom kom ua tau raws li qhov yuav tsum tau muaj ntawm ntau hom npog ntsej muag rau daim ntaub yaj.
Nyob rau hauv tus txheej txheem ntawm kev tsim pab pawg qauv, ua ntej, ua raws li txoj cai lij choj thiab cov kev cai, ua raws li cov hauv paus ntsiab lus ntawm kev qhib siab, pob tshab, thiab kev ncaj ncees, thiab nqus cov kev paub ntawm kev tsim khoom, tshuaj xyuas, thiab kev tswj xyuas cov ntaub yaj hauv Jiangsu Province, thiab tag nrho. xav txog cov technically advanced thiab economically ua tau zuag qhia tag nrho Cov yuav tsum tau, raws li lub teb chaws txoj cai, cov kev cai thiab cov qauv yuav tsum tau, tau lees paub los ntawm cov kws txawj nyob rau hauv lub ntsiab manufacturers ntawm melt blown fabrics, tshuaj xyuas cov koom haum, cov koom haum kev lag luam, cov tsev kawm ntawv qib siab thiab cov chaw tshawb fawb tshawb fawb hauv lub xeev, uas yog qhov tsim nyog rau lub luag haujlwm ntawm cov qauv kev qhia thiab kev tswj hwm. Qhov thib ob yog ua txoj haujlwm zoo ntawm kev sib txuas cov qauv ntawm cov khoom lag luam yaj-tshuab nrog cov qauv ntawm kev tiv thaiv lub ntsej muag, uas tuaj yeem ua lub luag haujlwm zoo hauv kev tsim qauv, txhim kho, thiab kho cov pab pawg ntawm kev lag luam los ntawm kev pom kev.
Kev tso tawm ntawm pab pawg txheej txheem yuav ua tau zoo ua lub luag haujlwm ntawm pab pawg txheej txheem "ceev, yoog raws thiab qib siab", pab cov khoom siv yaj-blown thiab cov lag luam ua haujlwm kom nkag siab zoo thiab ua tiav cov cim tseem ceeb ntawm cov ntaub yaj-tshuab rau qhov ncauj qhov ntswg, txhim kho cov khoom. cov qauv, thiab tsim raws li cov kev cai lij choj thiab cov kev cai Los muab kev txhawb nqa zoo rau kev tswj hwm kev lag luam ntawm cov ntaub qhwv yaj thiab ua kom cov khoom tiv thaiv kev sib kis tau zoo. Tom ntej no, raws li kev taw qhia ntawm Lub Chaw Saib Xyuas Kev Lag Luam Hauv Lub Xeev, Lub Tsev Haujlwm Saib Xyuas Kev Lag Luam Hauv Lub Xeev yuav ua haujlwm nrog Lub Tsev Haujlwm Saib Xyuas Kev Lag Luam Hauv Lub Xeev los txhais thiab tshaj tawm cov qauv thiab nthuav tawm cov kev paub zoo tshaj plaws ntsig txog cov ntaub npuag yaj. Nyob rau tib lub sijhawm, nws yuav ua txoj haujlwm zoo hauv kev tshaj tawm thiab siv cov qauv, kev cob qhia cov tuam txhab tsim khoom loj thiab cov thawj coj hauv nroog hauv lub xeev, thiab ntxiv kev cob qhia kev tsim khoom thiab kev saib xyuas ntawm cov ntaub nplaum tawg.
