Polypropylene nonwovens yog siv rau ntau qhov chaw xws li kev kho mob, kev tu cev, khoom siv tiv thaiv tus kheej (PPE), kev tsim kho, kev ua liaj ua teb, ntim khoom, thiab lwm yam. Txawm li cas los xij, thaum muab kev yooj yim rau tib neeg lub neej, lawv kuj tso lub nra hnyav rau ib puag ncig. Nws yog to taub hais tias nws cov pov tseg yuav siv sij hawm ntau pua xyoo kom decompose nyob rau hauv tej yam ntuj tso, uas yog ib tug mob taw tes nyob rau hauv kev lag luam rau ntau xyoo. Nrog rau kev paub txog kev tiv thaiv ib puag ncig hauv zej zog thiab kev nce qib ntawm kev lag luam ntau lawm technology, kev lag luam nonwovens yog nquag siv cov khoom lag luam thiab cov thev naus laus zis los txo qhov cuam tshuam rau ib puag ncig.
Txij li thaum Lub Xya Hli 2021, raws li EU's "Cov Lus Qhia Txog Kev Txom Nyem Ib puag ncig ntawm qee yam khoom siv yas" (Cov Lus Qhia 2019/904), oxidative degradable plastics tau raug txwv hauv EU vim tias lawv cuam tshuam los tsim cov pa phem microplastic.
Pib txij lub Yim Hli 1, 2023, cov khw noj mov, khw muag khoom, thiab cov tsev kawm ntawv pej xeem hauv Taiwan, Tuam Tshoj raug txwv tsis pub siv cov tais diav ua los ntawm polylactic acid (PLA), suav nrog cov phaj, bento ntim, thiab khob. Cov qauv ntawm cov compost degradation tau raug nug thiab tsis lees paub los ntawm ntau thiab ntau lub teb chaws thiab cheeb tsam.
Kev cog lus rau kev noj qab haus huv tib neeg ua pa thiab muab huab cua thiab dej huv,Medlong JOFOtau tsimPP biodegradable nonwoven ntaub. Tom qab cov ntaub raug muab faus rau hauv av, cov kab mob tshwj xeeb ua raws thiab tsim ib lub biofilm, nkag mus thiab nthuav cov saw hlau ntawm cov ntaub nonwoven, thiab tsim qhov chaw yug me nyuam kom nrawm decomposition. Nyob rau tib lub sijhawm, cov cim qhia tshuaj lom neeg tso tawm nyiam lwm cov kab mob sib kis los koom nrog kev noj zaub mov zoo, txhim kho kev ua haujlwm tsis zoo. Kev sim nrog siv rau ISO15985, ASTM D5511, GB / T 33797-2017 thiab lwm yam qauv, PP biodegradable nonwoven npuag muaj qhov degradation ntau dua 5% hauv 45 hnub, thiab tau txais daim ntawv pov thawj Intertek los ntawm lub koom haum thoob ntiaj teb. Piv nrog cov tsoos PPspun bonded nonwovens, PP biodegradable nonwovens tuaj yeem ua tiav degradation nyob rau hauv ob peb xyoos, txo lub voj voog biodegradation ntawm cov ntaub ntawv polypropylene, uas muaj qhov tseem ceeb rau kev tiv thaiv ib puag ncig.
Medlong JOFO biodegradable PP nonwoven fabrics ua tiav qhov tseeb ecological degradation. Hauv ntau qhov chaw pov tseg xws li kev pov tseg, dej hiav txwv, dej tsis qab, sludge anaerobic, siab anaerobic, thiab sab nraum zoov ib puag ncig, nws tuaj yeem ua rau ecologically degraded hauv 2 xyoos yam tsis muaj co toxins lossis microplastic residues.
Nyob rau hauv cov neeg siv scenarios, nws cov tsos, lub cev muaj zog, stability thiab lifespan yog tib yam li cov tsoos non-woven fabrics, thiab nws lub neej txee tsis cuam tshuam.
Tom qab siv lub voj voog dhau lawm, nws tuaj yeem nkag mus rau cov khoom siv rov ua dua tshiab thiab rov ua dua lossis rov ua dua ntau zaus, uas ua tau raws li cov kev xav tau ntawm ntsuab, qis-carbon, thiab txoj kev loj hlob.
