I-polypropylene nonwovens isetshenziswa emikhakheni eminingi efana nokunakekelwa kwezokwelapha, ukuhlanzeka, imishini yokuvikelwa komuntu (i-PPE), ukwakhiwa, ezolimo, ukupakisha, nabanye. Kodwa-ke, ngenkathi kuhlinzeka lula izimpilo zabantu, futhi zibeka umthwalo omkhulu emvelweni. Kuyaqondakala ukuthi imfucumfucu yayo ithatha amakhulu eminyaka ukubola ngokuphelele ngaphansi kwezimo zemvelo, obekuyiphuzu lobuhlungu embonini iminyaka eminingi. Ngokuqwashisa ngokwanda kokuvikelwa kwemvelo emphakathini kanye nentuthuko yobuchwepheshe bokukhiqiza imboni, imboni engeyona eye-nonwovens isebenzisa ngenkuthalo imikhiqizo eqhubekayo nobuchwepheshe ukunciphisa umthelela emvelweni.
Kusukela ngoJulayi 2021, ngokusho kwe-EU "eqondise ekwehliseni umthelela wezemvelo wemikhiqizo ethile yepulasitiki" (Umhlahlandlela ka-2019/904), amapulasitiki angenangqondo avinjelwe e-EU ngenxa yokuncipha kwawo ukukhiqiza ukungcoliswa kwawo kwe-microplastic.
Kusukela ngo-Agasti 1, 2023, izindawo zokudlela, izitolo zezitolo, kanye nezikhungo zomphakathi eTaiwan, iChina yavinjelwa ekusebenziseni i-Tableware eyenziwe ngePolylactic acid (PLA), kufaka phakathi amapuleti, neziqukathi ze-bento. Imodeli yokucekelwa phansi komquba ihlolwe futhi yakwenqatshwa ngamazwe amaningi kanye nezifunda.
Uzibophezele ekuphefumuleni komuntu okunempilo nokuhlinzeka ngomoya ohlanzekile namanzi,Medlong jofosekwenziweIndwangu ye-PP biodegradable nonwoven. Ngemuva kokuba izindwangu zingcwatshwe emhlabathini, ama-microorganisms azinikezele anamathela futhi wakhe i-biofilm, angene futhi andise uchungechunge lwe-polymer lwendwangu engeyona eye-nature, bese udala indawo yokuzalela ukusheshisa ukubola. Ngasikhathi sinye, amasiginali wamakhemikhali akhishwe amagciwane azokwazi ukuhlanganyela ekudleni, ekuthuthukiseni kahle ukusebenza kahle kokonakalisa. Kuhlolwe ngokubhekiswa ku-ISO15985, i-ASTM D5511, i-GB / T 33797-2017 namanye amazinga, futhi uthole isitifiketi se-Intertek esivela ezinsukwini ezingama-45. Qhathanisa ne-PP yendabukoI-Spun Bonded Nonwovens, Ama-Inonovens we-PP biodegradable angaqedela ukuwohloka okuphelele kungakapheli iminyaka embalwa, anciphise umjikelezo we-biodegradation wezinto zokwakha ama-polypropylene, ezinokubaluleka okuhle kokuvikelwa kwemvelo.
I-Medlong jodebradable PP izindwangu ezingenazo izindwangu zeqiniso zifinyelela ukonakaliswa kwemvelo kwangempela. Ezindaweni eziphansi zemfucumfucumfucumfucumo enjengokugcwaliswa komhlaba, wasolwandle, ama-freshwater, i-sludge anaerobic, izindawo eziphakeme zemvelo, zingawonakaliswa ngokuphelele izimo zemvelo kungakapheli ama-toxins noma izinsalela ezincane ze-microplastic.
Ezimweni zokusetshenziswa komsebenzisi, ukubukeka kwayo, izakhiwo ezibonakalayo, ukuqina kanye nokuphila kufana nezindwangu zendabuko ezingezona ezilukiwe, futhi impilo yayo yeshalofu ayithinteki.
Ngemuva kokuthi umjikelezo wokusebenzisa usuphelile, ungafaka uhlelo olujwayelekile lokuphinda usebenzise kabusha futhi asebenze kabusha noma asebenze kabusha izikhathi eziningi, ezihlangabezana nezidingo eziluhlaza, eziphansi zekhabhoni, nezentuthuko.
