Iingxowa zeti ezingenaplastiki? Ewe, uvile kakuhle loo nto...

Umenzi weTonchant iphepha lokucoca elingenaplastiki eliyi-100% leengxowa zeti,FUNDA OKUNGAKUMBI APHA

Ikomityi yakho yeti isenokuba neebhiliyoni ezili-11 zeeplastiki ezincinci kwaye oku kungenxa yendlela eyakhiwe ngayo ibhegi yeti.

Ngokutsho kophando lwakutshanje lwaseKhanada kwiYunivesithi yaseMcGill, ukufaka ibhegi yeti yeplastiki kubushushu obuyi-95°C kukhupha malunga ne-11.6 yeebhiliyoni zeeplastiki ezincinci - iziqwenga ezincinci zeplastiki eziphakathi kwe-100 nanometers kunye ne-5 millimeters ngobukhulu - kwikomityi enye. Xa kuthelekiswa netyuwa, umzekelo, ekwafunyaniswa ukuba ineplastiki, ikomityi nganye ineeplastiki ezininzi ngokuphindwe kangamawaka, kwi-16 micrograms kwikomityi nganye.

Ukwanda kobukho beeplastiki ezincinci nezincinci kwindalo esingqongileyo nakwikhonkco lokutya kuyaxhalabisa kakhulu. Nangona abathengi abalumkileyo bekhuthaza ukunciphisa iiplastiki ezisetyenziswa kanye, abanye abavelisi benza ukupakisha kweplastiki okutsha ukuze kuthathe indawo yokusetyenziswa kwephepha lemveli, njengeengxowa zeti zeplastiki. Injongo yolu phononongo yayikukufumanisa ukuba iingxowa zeti zeplastiki zinokukhupha iiplastiki ezincinci kunye/okanye iiplastiki ezincinci ngexesha lenkqubo eqhelekileyo yokucwilisa. Sibonisa ukuba ukucwilisa ingxowa yeti yeplastiki enye kubushushu bokuyenza (95 °C) kukhupha malunga ne-11.6 yeebhiliyoni zeeplastiki ezincinci kunye ne-3.1 yeebhiliyoni zeeplastiki ezincinci kwikomityi enye yesiselo. Ukwakheka kweengqayi ezikhutshiweyo kuhambelana neengxowa zeti zokuqala (i-nylon kunye ne-polyethylene terephthalate) kusetyenziswa i-Fourier-transform infrared spectroscopy (FTIR) kunye ne-X-ray photoelectron spectroscopy (XPS). Amanqanaba eengqayi ze-nylon kunye ne-polyethylene terephthalate ezikhutshiweyo kwiphakheji yeengxowa zeti aphezulu kakhulu kunemithwalo yeplastiki ebikwe ngaphambili kwezinye ukutya. Uvavanyo lokuqala lwetyhefu yezilwanyana ezingenamqolo lubonisa ukuba ukuchatshazelwa kuphela ziinxalenye ezikhutshwa kwiingxowa zeti kubangele iziphumo ezixhomekeke kumthamo wokuziphatha kunye nophuhliso.
