I-PET (i-Polyethylene Terephthalate) isetshenziswa kabanzi embonini yokupakisha. Ngokukhula kokuqwashisa ngezemvelo emhlabeni wonke, amathuba emakethe yesikhathi esizayo kanye nomthelela wemvelo wamapulasitiki e-PET athola ukunakwa okukhulu.
Okwedlule Kwe-PET Material
Maphakathi nekhulu lama-20, i-PET polymer ephawulekayo, i-Polyethylene Terephthalate, yaqala ukusungulwa. Abaqambi bafuna into engase isetshenziselwe izinjongo ezihlukahlukene zezohwebo. Ukungasindi kwayo, ukucaca, nokuqina kwayo kukwenze kwaba ukukhetha okuhle kwezinhlelo zokusebenza ezisabalele. Ekuqaleni, i-PET yayisetshenziswa ngokuyinhloko embonini yendwangu njengempahla eluhlaza yamafayibha okwenziwa (i-polyester). Ngokuhamba kwesikhathi, ukusetshenziswa kwe-PET kancane kancane kwanda emkhakheni wokupakisha, ikakhulukazi kuamabhodlela esiphuzo kanye nokupakisha ukudla.
Ukufika kwamabhodlela e-PET ngeminyaka yawo-1970 kwaphawula ukukhula kwawo embonini yokupakisha.PET amabhodlela kanyeI-PET yokuphuza indebe, ngesisindo sawo esingasindi, amandla aphezulu, nokungafihli kahle, kwashintsha ngokushesha amabhodlela engilazi namakani ensimbi, kwaba into ethandwayo yokupakishwa kwesiphuzo. Ngokuthuthuka okuqhubekayo kubuchwepheshe bokukhiqiza, izindleko zezinto ze-PET zehla kancane kancane, zaphinde zathuthukisa ukusetshenziswa kwazo okusabalele emakethe yomhlaba.
Ukunyuka kanye Nezinzuzo ze-PET
Ukukhuphuka okusheshayo kwezinto ze-PET kungenxa yezinzuzo zayo eziningi. Okokuqala, i-PET inezinto ezinhle kakhulu zomzimba, ezinjengamandla aphezulu, ukumelana nokugqoka, nokumelana nokubola kwamakhemikhali, okuyenza isebenze kahle emikhakheni yokupakisha nezimboni. Okwesibili, impahla ye-PET inokucaca okuhle nokucwebezela, ikunikeza umphumela omuhle kakhulu wokubukwa ezinhlelweni ezinjengamabhodlela eziphuzo nezitsha zokudla.
Ngaphezu kwalokho, ukugaywa kabusha kwezinto ze-PET nakho kuyinzuzo enkulu. Amapulasitiki e-PET angagaywa kabusha futhi asetshenziswe kabusha ngezindlela ezibonakalayo noma zamakhemikhali ukuze kukhiqizwe izinto ezigaywe kabusha ze-PET (rPET). Izinto ze-rPET azikwazi ukusetshenziselwa kuphela ukukhiqiza amabhodlela e-PET amasha kodwa futhi zisetshenziselwe izindwangu, ukwakhiwa, nakweminye imikhakha, zinciphisa kakhulu umthelela wemvelo wemfucuza yepulasitiki.
Umthelela Wezemvelo
Naphezu kwezinzuzo eziningi zezinto ze-PET, umthelela wazo wemvelo awukwazi ukushaywa indiva. Inqubo yokukhiqiza yamapulasitiki e-PET idla isamba esikhulu semithombo ye-petroleum futhi ikhiqize ukukhishwa kwesisi esibamba ukushisa. Ukwengeza, izinga lokuwohloka kwamapulasitiki e-PET endaweni yemvelo lihamba kancane, ngokuvamile lidinga amakhulu eminyaka, okuwenza abe umthombo omkhulu wokungcola kwepulasitiki.
Nokho, uma kuqhathaniswa nezinye izinhlobo zamapulasitiki, ukugaywa kabusha kwe-PET kuyinikeza inzuzo ethile ekuvikelweni kwemvelo. Izibalo zibonisa ukuthi cishe u-26% wamapulasitiki e-PET agaywa kabusha emhlabeni jikelele, ingxenye ephakeme kakhulu kunezinye izinto zepulasitiki. Ngokwandisa izinga lokugaywa kabusha kwamapulasitiki e-PET, umthelela wawo omubi emvelweni ungancishiswa ngempumelelo.

Nokho, uma kuqhathaniswa nezinye izinhlobo zamapulasitiki, ukugaywa kabusha kwe-PET kuyinikeza inzuzo ethile ekuvikelweni kwemvelo. Izibalo zibonisa ukuthi cishe u-26% wamapulasitiki e-PET agaywa kabusha emhlabeni jikelele, ingxenye ephakeme kakhulu kunezinye izinto zepulasitiki. Ngokwandisa izinga lokugaywa kabusha kwamapulasitiki e-PET, umthelela wawo omubi emvelweni ungancishiswa ngempumelelo.
Umthelela Wezemvelo Wezinkomishi Ezilahlwayo ze-PET
Njengento evamile yokupakisha ukudla nesiphuzo, umthelela wemvelo wePET izinkomishi ezilahlwayofuthi kuyinkinga enkulu. Yize izinkomishi zesiphuzo ze-PET nezinkomishi zetiye lezithelo ze-PET zinezinzuzo ezifana nokuba zingasindi, zibe sobala, futhi zithandeke ngobuhle, ukusetshenziswa kwazo kakhulu nokulahlwa okungafanele kungaholela ezinkingeni ezinkulu zemvelo.
Izinga lokuwohloka kwezinkomishi ezilahlwayo ze-PET endaweni yemvelo lihamba kancane kakhulu. Uma zingaphinde zisetshenziswe, zingadala umonakalo wesikhathi eside kuma-ecosystem. Ukwengeza, izinkomishi ezilahlwayo ze-PET zingase zibe izingozi ezithile zempilo lapho zisetshenziswa, njengokukhishwa kwezinto eziyingozi ngaphansi kwezimo ezishisa kakhulu. Ngakho-ke, ukukhuthaza ukugaywa kabusha nokusetshenziswa kabusha kwezinkomishi ezilahlwayo ze-PET ukuze kwehliswe umthelela wazo endaweni ezungezile kuyindaba ephuthumayo okufanele ixazululwe.
Ezinye Izicelo ze-PET Plastics
Ngaphandle kwamabhodlela eziphuzo kanye nokupakishwa kokudla, amapulasitiki e-PET asetshenziswa kakhulu kweminye imikhakha. Embonini yendwangu, i-PET, njengempahla eluhlaza eyinhloko yamafayili e-polyester, isetshenziswa kakhulu ekukhiqizeni izingubo zokugqoka kanye nezindwangu zasekhaya. Emkhakheni wezimboni, amapulasitiki e-PET, ngenxa yezakhiwo zawo ezinhle kakhulu, asetshenziswa ekukhiqizeni izingxenye ze-elekthronikhi nezingxenye zezimoto.
Ngaphezu kwalokho, izinto ze-PET zinezicelo ezithile emikhakheni yezokwelapha neyokwakha. Isibonelo, i-PET ingasetshenziselwa ukukhiqiza amadivaysi ezokwelapha kanye nokupakishwa kwemithi ngenxa ye-biocompatibility yayo enhle nokuphepha. Embonini yezokwakha, izinto ze-PET zingasetshenziswa ukukhiqiza izinto zokufakelwa kanye nezinto zokuhlobisa, ezaziwa ngokuqina kwazo kanye nobungane bemvelo.
Imibuzo Evame Ukubuzwa MayelanaPET izinkomishi
1. Ingabe izinkomishi ze-PET ziphephile?
Izinkomishi ze-PET ziphephile ngaphansi kwezimo ezijwayelekile zokusetshenziswa futhi zithobela izindinganiso ezifanele zezinto zokuxhumana zokudla. Kodwa-ke, bangase bakhulule ukulandelela amanani ezinto eziyingozi ngaphansi kwezimo eziphezulu zokushisa, ngakho-ke kunconywa ukugwema ukusebenzisa izinkomishi ze-PET ezindaweni ezishisa kakhulu.
2. Ingabe izinkomishi ze-PET zingasetshenziswa kabusha?
Izinkomishi ze-PET ziyakwazi ukuphinda zisetshenziswe futhi zingacutshungulwa zibe izinto ze-PET ezigaywe kabusha ngezindlela ezingokwenyama noma zamakhemikhali. Kodwa-ke, izinga langempela lokuphinda ligaywe linqunyelwe ukuphelela kwesistimu yokugaywa kabusha nokuqwashisa kwabathengi.
3. Uyini umthelela wemvelo wezinkomishi ze-PET?
Izinga lokuwohloka kwezinkomishi ze-PET endaweni yemvelo lihamba kancane, okungase kubangele imithelela yesikhathi eside kuzinhlelo zemvelo. Ukwenyusa izinga lokugaywa kabusha kanye nokukhuthaza ukusetshenziswa kwezinto ze-PET ezigaywe kabusha kuyizindlela ezisebenzayo zokunciphisa umthelela wazo kwezemvelo.
Ikusasa Le-PET Material
Ngokukhula kokuqwashisa ngezemvelo emhlabeni wonke kanye nentuthuko yezobuchwepheshe eqhubekayo, izinto ze-PET zizobhekana namathuba amasha okuthuthukiswa nezinselele esikhathini esizayo. Ngakolunye uhlangothi, ngokuvuthwa okuqhubekayo kobuchwepheshe bokugaywa kabusha, izinga lokugaywa kabusha kwezinto ze-PET kulindeleke ukuthi lithuthuke nakakhulu, ngaleyo ndlela kwehle umthelela wazo omubi kwezemvelo. Ngakolunye uhlangothi, ucwaningo kanye nokusetshenziswa kwezinto ezisekelwe ku-bio-based PET (Bio-PET) nakho kuyathuthuka, kuhlinzeka ngezikhombisi-ndlela ezintsha zokuthuthukiswa okuqhubekayo kwezinto ze-PET.
Esikhathini esizayo,PET isiphuzo izinkomishi, izinkomishi zetiye lezithelo ze-PET, nezinkomishi ezilahlwayo ze-PET zizonaka kakhulu ukusebenza kwemvelo nokuphepha kwezempilo, kukhuthaze intuthuko esimeme. Ngaphansi kwesizinda sokuthuthukiswa kokuluhlaza komhlaba, ikusasa lezinto ze-PET ligcwele ithemba namathuba. Ngokusungula izinto ezintsha nomzamo oqhubekayo, amapulasitiki e-PET kulindeleke ukuthi athole ibhalansi phakathi kokuhlangabezana nesidingo semakethe esizayo nokuvikelwa kwemvelo, abe yimodeli yokupakishwa okuluhlaza.
Ukuthuthukiswa kwamapulasitiki e-PET akumele kugxile ekudingeni izimakethe kuphela kodwa nomthelela wemvelo. Ngokwandisa izinga lokugaywa kabusha, ukukhuthaza ukusetshenziswa kwezinto ze-PET ezigaywe kabusha, kanye nokuthuthukisa ucwaningo nokuthuthukiswa kwe-PET esekwe ku-bio, amapulasitiki e-PET kulindeleke ukuthi athole ibhalansi entsha phakathi kwezidingo zemakethe zesikhathi esizayo nokuvikelwa kwemvelo, ahlangabezane nezidingo ezimbaxambili.
