Iikomityi zamanzi zeplastiki zitshiphu, zikhaphukhaphu kwaye ziyasebenza, kwaye zikhawuleze zaduma kwihlabathi liphela ukusukela ngo-1997. Nangona kunjalo, kwiminyaka yakutshanje, iikomityi zamanzi zeplastiki ziye zafumana ukuthengiswa okucothayo.Siyintoni isizathu sale nto?Masiqale ngeenzuzo kunye nokungonakali kweekomityi zamanzi zeplastiki.
Kuyaziwa ukuba iikomityi zamanzi zeplastiki zilula.Kuba izinto zeplastiki zilula ukumila, imilo yeekomityi zamanzi zeplastiki iya kuba yeyomntu kwaye ibe nefashoni xa kuthelekiswa neekomityi zamanzi ezenziwe ngezinye izinto.Inkqubo yokucubungula iikomityi zamanzi zeplastiki ilula, ixabiso lezinto eziphathekayo liphantsi, umjikelo wokucubungula umfutshane, isantya sikhawuleza, izinga lemveliso ephosakeleyo kunye nezinye izizathu zikhokelela kwixabiso eliphantsi leekomityi zamanzi zeplastiki.Ezi luncedo kwiikomityi zamanzi zeplastiki.
Nangona kunjalo, iikomityi zamanzi zeplastiki nazo zineentsilelo ezithile, ezifana nokuqhekeka ngenxa yempembelelo yendalo kunye nobushushu bamanzi, kwaye iikomityi zeplastiki azixhathisi ukuwa.Ingxaki enkulu kakhulu kukuba phakathi kwazo zonke izinto zeplastiki zangoku, azininzi ezingenabungozi ngokwenene, nangona izixhobo ezininzi zeplastiki ziyibakala lokutya, kodwa emva kokuba iimfuno zeqondo lokushisa zigqithisiwe, ziya kuba yinto enobungozi, njenge-PC kunye ne-AS.Emva kokuba ubushushu bamanzi budlule kwi-70 ° C, izinto eziphathekayo ziya kukhulula i-bisphenol A, enokuthi ikhubaze okanye iphule ikomityi yamanzi.Kungenxa yokuba izinto eziphathekayo azikwazi ukuhlangabezana neemfuno zokhuseleko lwabantu ukuba iikomityi zamanzi zeplastiki ngaphandle kwe-tritan ziye zanqatshelwa ngokungqongqo ukuba zingene kwimarike kwimarike yaseYurophu ukususela ngo-2017. amazwe kunye nemimandla yaqala ukumisela izithintelo kwizinto zeplastiki.Iikomityi zamanzi zineemfuno eziphezulu kunye nezithintelo.Oku kubangele ukuba imakethi yekomityi yamanzi yeplastiki iqhubeke nokuhla kule minyaka idlulileyo.
Njengoko impucuko yabantu iqhubela phambili kwaye itekhnoloji iqhubeka nokwenza izinto ezintsha, izinto ezintsha zeplastiki ziya kuzalwa kwimarike, njengezinto ze-tritan, eziye zamkelwa yimarike yehlabathi kwiminyaka yakutshanje.Oku kwaphuhliswa yi-American Eastman Company kwaye ijolise kwizinto zeplastiki zemveli., ehlala ixesha elide, ekhuselekileyo, ekwazi ukumelana nobushushu obuphezulu, ayinakonakala, kwaye ayinayo i-bisphenol A. Izinto ezinjengalezi ziya kuqhubeka ziphuhliswa ngokuphuhliswa kobuchwepheshe, kwaye iikomityi zamanzi zeplastiki nazo ziya kuhamba ukusuka kwelinye isitya ukuya kwelinye.
