I-polypropylene nonwovens isetshenziswa emikhakheni eminingi njengokunakekelwa kwezempilo, inhlanzeko, okokuvikela umuntu (i-PPE), ukwakhiwa, ezolimo, ukupakisha nokunye. Kodwa-ke, ngenkathi benikeza ukuphila kalula, baphinde babeke umthwalo omkhulu endaweni ezungezile. Kuyaqondakala ukuthi imfucuza yayo ithatha amakhulu eminyaka ukubola ngokuphelele ngaphansi kwezimo zemvelo, okuye kwaba iphuzu elibuhlungu embonini iminyaka eminingi. Ngokuqwashisa okwandayo kokuvikelwa kwemvelo emphakathini kanye nokuthuthuka kobuchwepheshe bokukhiqiza imboni, imboni ye-nonwovens isabalalisa imikhiqizo eqhubekayo nobuchwepheshe ukunciphisa umthelela emvelweni.
Kusukela ngoJulayi 2021, ngokomthetho we-EU "wokunciphisa umthelela wemvelo wemikhiqizo ethile yepulasitiki" (I-Directive 2019/904), amapulasitiki awonakala nge-oxidative avinjelwe e-EU ngenxa yokuhlakazeka kwawo ukuze akhiqize ukungcoliswa kwe-microplastic.
Kusukela ngomhla ka-1 Agasti 2023, izindawo zokudlela, izitolo, nezikhungo zomphakathi e-Taiwan, e-China baye bavinjelwa ukusebenzisa i-tableware eyenziwe nge-polylactic acid (PLA), okuhlanganisa amapuleti, izitsha ze-bento, nezinkomishi. Imodeli yokucekelwa phansi komquba iye yabuzwa futhi yanqatshwa amazwe amaningi nezifunda.
Ukuzibophezela ekuphefumuleni komuntu okunempilo nokunikeza umoya namanzi ahlanzekile,Medlong JOFOithuthukileIndwangu engalukiwe ye-PP engaboli. Ngemuva kokuthi izindwangu zigqitshwe enhlabathini, ama-microorganisms azinikele anamathela futhi enze i-biofilm, angene futhi andise uchungechunge lwe-polymer lwendwangu engalukiwe, futhi adale indawo yokuzalanisa ukusheshisa ukubola. Ngasikhathi sinye, izimpawu zamakhemikhali ezikhishwe ziheha amanye ama-microorganisms ukuthi abambe iqhaza ekondleni, okwenza ngcono kakhulu ukusebenza kahle kokuwohloka. Ihlolwe kubhekiselwa ku-ISO15985, ASTM D5511, GB/T 33797-2017 namanye amazinga, indwangu engalukiwe engalukiwe ye-PP inezinga lokuwohloka elingaphezu kuka-5% phakathi kwezinsuku ezingama-45, futhi ithole isitifiketi se-EUROLAB kusuka enhlanganweni egunyazwe emhlabeni jikelele. Uma kuqhathaniswa ne-PP yendabukoama-nonwovens aboshwe ngesibopho, I-PP biodegradable nonwovens ingaqeda ukuwohloka phakathi neminyaka embalwa, inciphise umjikelezo we-biodegradation wezinto ze-polypropylene, ezinokubaluleka okuhle ekuvikelweni kwemvelo.
I-Medlong JOFO izindwangu ze-PP ezingalukiwe ezingaboli zifinyelela ukucekelwa phansi kwemvelo kweqiniso. Ezindaweni ezihlukene zemfucumfucu efana nokulahlwa kwemfucuza, olwandle, amanzi ahlanzekile, i-sludge anaerobic, i-anaerobic eqinile eqinile, kanye nezindawo zemvelo zangaphandle, ingonakaliswa ngokuphelele imvelo phakathi neminyaka emi-2 ngaphandle kobuthi noma izinsalela zepulasitiki.
Ezimeni zokusetshenziswa kwabasebenzisi, ukubukeka kwayo, izakhiwo ezingokomzimba, ukuzinza kanye neminyaka yokuphila kuyafana nezindwangu ezingezona ezilukiwe ezivamile, futhi ukuphila kwayo kweshalofu akuthinteki.
Ngemva kokuphela komjikelezo wokusebenzisa, ingangena ohlelweni oluvamile lokugaywa kabusha futhi igaywe kabusha noma igaywe kabusha izikhathi eziningi, ehlangabezana nezidingo zokuthuthukiswa okuluhlaza, okunekhabhoni ephansi, kanye nendingilizi.
