Kev kho mob ntsuab yog qhov tseem ceeb ntawm txoj kev loj hlob niaj hnub no, thiab qhov tshwm sim ntawmBiodegradable PLA (polylactic acid) spunbond nonwoven fabricsmuab txoj hauv kev tshiab rau kev txo qis ib puag ncig siab los ntawm kev kho mob pov tseg.
Kev siv kho mob ntawm PLAT spunbond ntaub
PLA spunbond npuag tau pom muaj peev xwm hauv ntau yam khoom kho mob vim nws cov yam ntxwv:
Cov khoom siv tiv thaiv: PLA spunbond npuag tuaj yeem siv los ua cov ris tsho phais, phais drapes, hnab tshuaj tua kab mob, thiab lwm yam. Kev tshawb fawb kuj tsim PLA raws li SMS (spunbond meltblown spunbond) cov khoom siv, uas tuaj yeem siv rau cov khoom siv tiv thaiv kev kho mob uas yuav tsum muaj kev pom zoo.
Cov khoom siv tshuaj tua kab mob: Los ntawm kev ntxiv cov tshuaj tua kab mob inorganic xws li nano zinc oxide (ZnO) rau PLA, cov ntaub tsis-woven nrog cov khoom siv tshuaj tua kab mob ntev thiab nyab xeeb tuaj yeem npaj tau. Piv txwv li, thaum cov ntsiab lus ZnO yog 1.5%, tus nqi tshuaj tua kab mob tiv thaiv Escherichia coli thiab Staphylococcus aureus tuaj yeem ncav cuag ntau dua 98%. Cov khoom lag luam no tuaj yeem siv rau lub sijhawm uas muaj cov kab mob siab tiv thaiv kab mob, xws li hnav khaub ncaws kho mob, cov ntaub pua tsev pov tseg, thiab lwm yam.
Kev ntim khoom kho mob thiab cov twj paj nruag: PLA tsis-woven npuag tuaj yeem siv rau ntim cov khoom siv kho mob. Nws txoj kev ua pa zoo tso cai rau kom tsis muaj cov pa roj xws li ethylene oxide nkag mus, thaum thaiv cov kab mob zoo. PLA nanofiber membrane kuj tseem siv tau rau cov ntaub ntawv pom zoo.
Ib puag ncig cov txiaj ntsig thiab kev sib tw
Cov txiaj ntsig tseem ceeb ntawm ib puag ncig: Kev siv PLA spunbond npuag pab txo qis kev siv roj av los ntawm cov khoom siv kho mob pov tseg. Tom qab muab pov tseg, nws tuaj yeem ua tiav biodegraded nyob rau hauv cov txheej txheem composting, koom nrog hauv kev ncig hauv ntuj, thiab pab txo qis ib puag ncig tuav thiab "dawb paug" ntawm cov pov tseg kho mob.
Cov teeb meem ntsib: Kev nce qib ntawm PLA spunbond npuag hauv kev kho mob tseem ntsib qee qhov teeb meem. Piv txwv li, cov ntaub ntawv PLA ntshiab muaj teeb meem xws li muaj zog hydrophobicity, nkig kev ntxhib los mos, thiab xav tau los txhim kho cov cua sov. Txawm li cas los xij, cov teeb meem no tau maj mam hais los ntawm kev hloov kho cov ntaub ntawv thiab cov txheej txheem optimization. Los ntawm kev npaj PLA copolymer fibers, lawv qhov nqus dej noo thiab ua kom sov tuaj yeem txhim kho. Kev sib xyaw PLA nrog lwm cov biopolymers xws li PHBV kuj tau raug pov thawj tias yog ib txoj hauv kev zoo los txhim kho nws cov khoom siv thiab kev ua haujlwm.
Txoj kev txhim kho yav tom ntej
Kev txhim kho yav tom ntej ntawm PLA spunbond npuag hauv kev kho mob yuav muaj cov hauv qab no:
Kev hloov kho cov ntaub ntawv txuas ntxiv mus ntxiv: yav tom ntej, kev tshawb fawb yuav txuas ntxiv txhim kho cov khoom ntawm PLA spunbond npuag los ntawm copolymerization, blending, thiab ntxiv cov khoom ntxiv (xws li siv cov saw txuas ntxiv thiab cov tshuaj antioxidants los txhim kho cov txheej txheem ntawm PLA), xws li kev txhim kho nws yooj yim, breathability, thiab noo noo permeability, kom tau raws li cov kev xav tau ntau dua rau kev siv kho mob.
Muaj kev sib koom ua ke thiab kev txhawb nqa technology: Kev txhim kho ntxiv ntawmPLA spunbond ntaubtso siab rau kev sib koom ua ke ntawm kev lag luam, kev kawm, thiab kev tshawb fawb los txhawb kev ua tiav hauv cov thev naus laus zis tseem ceeb thiab kev nthuav dav ntawm kev lag luam kev lag luam. Qhov no suav nrog kev ua kom zoo dua qhov kev sib tw ntawm PLA copolyesters thiab txhim kho kev lag luam txuas ntxiv mus rau PLA raws li SMS qauv.
Dual tsav ntawm kev txhawb nqa txoj cai thiab kev lag luam xav tau: Nrog rau kev tso tawm ntawm "cov phiaj xwm txwv txiav yas" hauv Hainan thiab lwm thaj chaw, nrog rau lub ntiaj teb tseem ceeb ntawm kev tsim kho kom ruaj khov thiab kev lag luam ncig, cov kev cai ib puag ncig yuav txuas ntxiv tsim qhov chaw lag luam dav rau cov khoom siv biodegradable.
Cov ntsiab lus
Degradable PLA spunbond npuag, nrog rau nws qhov zoo ntawm kev tiv thaiv ib puag ncig ntsuab, cov khoom siv txuas ntxiv dua tshiab, biodegradability, thiab muaj peev xwm ua haujlwm, muab kev xaiv tshiab rau kev lag luam kho mob kom txo qis ib puag ncig thiab xav tias yuav coj mus rau lub sijhawm ntawm kev tiv thaiv ib puag ncig rau cov khoom siv kho mob pov tseg.
Txawm hais tias kev txhim kho txuas ntxiv tseem xav tau hauv cov khoom siv thiab kev tswj hwm tus nqi, nrog rau kev nce qib ntawm kev siv thev naus laus zis, kev loj hlob ntawm kev lag luam, thiab kev txhawb nqa ntawm ib puag ncig cov cai, daim ntawv thov kev cia siab ntawm PLA spunbond npuag hauv kev kho mob yog qhov zoo heev.
Kuv vam tias cov ntaub ntawv saum toj no tuaj yeem pab koj nkag siab zoo dua PLA spunbond ntaub. Yog tias koj muaj kev txaus siab ntxiv rau qee yam ntawm PLA cov khoom kho mob, xws li cov khaub ncaws tiv thaiv qib siab lossis cov khaub ncaws tiv thaiv kab mob tshwj xeeb, peb tuaj yeem tshawb xyuas ntxiv.
Dongguan Liansheng Nonwoven Technology Co., Ltd.tau tsim nyob rau hauv lub Tsib Hlis 2020. Nws yog ib tug loj-scale non-woven npuag ntau lawm enterprise integrating kev tshawb fawb thiab kev loj hlob, ntau lawm, thiab muag khoom. Nws tuaj yeem tsim ntau yam xim ntawm PP spunbond non-woven fabrics nrog qhov dav ntawm tsawg dua 3.2 meters los ntawm 9 grams mus rau 300 grams.
