I-PET (i-Polyethylene Terephthalate) yinto esetyenziswa ngokubanzi kwiplastiki kwishishini lokupakisha. Ngokunyuka kolwazi lokusingqongileyo lwehlabathi, amathuba emarike exesha elizayo kunye nefuthe lokusingqongileyo kweeplastiki zePET afumana ingqwalasela enkulu.
Ixesha elidlulileyo le-PET Material
Embindini wenkulungwane yama-20, i-PET polymer ephawulekayo, iPolyethylene Terephthalate, yaqala ukuyilwa. Abaqambi bafuna izinto ezinokusetyenziswa kwiinjongo ezahlukeneyo zorhwebo. Ubunzima bayo, ukungafihli, kunye nokomelela kwenze ukuba ibe lolona khetho lufanelekileyo kusetyenziso olubanzi. Ekuqaleni, i-PET yayisetyenziswa ikakhulu kwishishini lelaphu njengemathiriyeli ekrwada yee-synthetic fibers (i-polyester). Ngokuhamba kwexesha, ukusetyenziswa kwePET ngokuthe ngcembe kwanda kwicandelo lokupakisha, ngakumbi kwiiibhotile zesiselo kunye nokupakishwa kokutya.
Ukufika kweebhotile ze-PET kwiminyaka ye-1970 kwaphawula ukunyuka kwayo kwishishini lokupakisha.Iibhotile zePET kunyePET indebe yokusela, kunye nokukhanya kwabo, amandla aphezulu, kunye nokubonakala kakuhle, ngokukhawuleza batshintshe iibhotile zeglasi kunye neetoti zetsimbi, zibe yinto ekhethiweyo yokupakisha isiselo. Ngokuqhubela phambili okuqhubekayo kwitekhnoloji yemveliso, amaxabiso ezinto ze-PET ancipha ngokuthe ngcembe, ekhuthaza ngakumbi ukusetyenziswa kwawo kwintengiso yehlabathi.
Ukunyuka kunye nokuNceda kwePET
Ukunyuka ngokukhawuleza kwezinto ze-PET kungenxa yeenzuzo zayo ezininzi. Okokuqala, i-PET ineempawu ezibalaseleyo zomzimba, ezinje ngokuqina okuphezulu, ukuxhathisa ukunxiba, kunye nokuxhathisa ukubola kweekhemikhali, nto leyo eyenza ukuba isebenze kakuhle kumhlaba wokupakisha nakwimizi-mveliso. Okwesibini, imathiriyeli ye-PET inokucaca kakuhle kunye ne-luster, inika umbono obalaseleyo kwizicelo ezinjengeebhotile zesiselo kunye nezitya zokutya.
Ngapha koko, ukuphinda kusetyenziswe izinto ze-PET kukwaluncedo olukhulu. Iiplastiki ze-PET zinokuphinda zisetyenziswe kwaye ziphinde zisetyenziswe ngeendlela eziphathekayo okanye zekhemikhali ukuvelisa izinto ze-PET (rPET) ezisetyenzisiweyo. Izixhobo ze-rPET azinakusetyenziselwa kuphela ukuvelisa iibhotile ze-PET ezintsha kodwa zikwasetyenziselwa impahla, ulwakhiwo, kunye namanye amacandelo, ukunciphisa kakhulu impembelelo yokusingqongileyo yenkunkuma yeplastiki.
Impembelelo yokusingqongileyo
Ngaphandle kweenzuzo ezininzi zezinto ze-PET, impembelelo yazo yokusingqongileyo ayinakuhoywa. Inkqubo yokuveliswa kweeplastiki ze-PET idla isixa esikhulu semithombo yepetroleum kwaye ivelisa ukukhutshwa kwegesi yegreenhouse. Ukongeza, izinga lokuthotywa kweeplastiki ze-PET kwindawo yendalo licotha kakhulu, lihlala lifuna amakhulu eminyaka, lizenza zibe ngumthombo omkhulu wongcoliseko lweplastiki.
Nangona kunjalo, xa kuthelekiswa nezinye iintlobo zeeplastiki, ukuphinda kusetyenziswe i-PET kukunika inzuzo ethile ekukhuselweni kwendalo. Izibalo zibonisa ukuba malunga ne-26% yeeplastiki ze-PET ziphinda zisetyenziswe kwihlabathi jikelele, umlinganiselo ophezulu kakhulu kunezinye izinto zeplastiki. Ngokunyusa izinga lokurisayikilishwa kweeplastiki zePET, impembelelo yazo engalunganga kokusingqongileyo inokuncipha ngokufanelekileyo.
Impembelelo yokusingqongileyo

Ukongeza, izinga lokuthotywa kweeplastiki ze-PET kwindawo yendalo licotha kakhulu, lihlala lifuna amakhulu eminyaka, lizenza zibe ngumthombo omkhulu wongcoliseko lweplastiki.
Nangona kunjalo, xa kuthelekiswa nezinye iintlobo zeeplastiki, ukuphinda kusetyenziswe i-PET kukunika inzuzo ethile ekukhuselweni kwendalo. Izibalo zibonisa ukuba malunga ne-26% yeeplastiki ze-PET ziphinda zisetyenziswe kwihlabathi jikelele, umlinganiselo ophezulu kakhulu kunezinye izinto zeplastiki. Ngokunyusa izinga lokurisayikilishwa kweeplastiki zePET, impembelelo yazo engalunganga kokusingqongileyo inokuncipha ngokufanelekileyo.
Impembelelo yokusiNgqongileyo ye-PET Disposable Cups
Njengokutya okuqhelekileyo kunye nezixhobo zokupakisha isiselo, impembelelo yokusingqongileyoPET iikomityi ezilahlwayoikwayinkxalabo ebalulekileyo. Nangona iikomityi zesiselo se-PET kunye neekomityi zeti yeziqhamo ze-PET zinezibonelelo ezinjengokukhaphukhaphu, ukungafihli, kunye nokuthandeka ngobuhle, ukusetyenziswa kwazo kakhulu kunye nokulahlwa ngokungafanelekanga kunokukhokelela kwimiba enzulu yokusingqongileyo.
Izinga lokuthotywa kweekomityi ezilahlwayo ze-PET kwindawo yendalo licotha kakhulu. Ukuba aziphinda zisetyenziswe, zingenza umonakalo wexesha elide kwi-ikhosistim. Ukongezelela, iikomityi ezilahlwayo zePET zisenokubangela iingozi ezithile zempilo xa zisetyenziswa, njengokukhupha izinto eziyingozi phantsi kweemeko zobushushu obuphezulu. Ngoko ke, ukukhuthaza ukuhlaziywa kunye nokusetyenziswa kwakhona kweekomityi ezilahlayo ze-PET ukunciphisa impembelelo yazo yokusingqongileyo ngumba ongxamisekileyo ofuna ukuqwalaselwa.
Olunye usetyenziso lwePlastiki yePET
Ngaphandle kweebhotile zesiselo kunye nokupakishwa kokutya, iiplastiki zePET zisetyenziswa ngokubanzi kwamanye amasimi. Kushishino lwamalaphu, i-PET, njengesona sixhobo siphambili sokwenziwa kweentsinga zepolyester, isetyenziswa kakhulu ekuveliseni impahla kunye namalaphu asekhaya. Kwicandelo loshishino, iiplastiki ze-PET, ngenxa yeempawu zazo ezibalaseleyo, zisetyenziselwa ukuvelisa izinto ze-elektroniki kunye neenxalenye zemoto.
Ngaphaya koko, izixhobo ze-PET zinezicelo ezithile kunyango kunye nolwakhiwo. Ngokomzekelo, i-PET ingasetyenziselwa ukuvelisa izixhobo zonyango kunye nokupakishwa kwamayeza ngenxa ye-biocompatibility efanelekileyo kunye nokhuseleko. Kwishishini lokwakha, izinto ze-PET zingasetyenziselwa ukuvelisa izinto zokugquma kunye nezinto zokuhombisa, ezaziwa ngokuhlala kwazo kunye nobuhlobo bendalo.
