Izinkomishi zamanzi epulasitiki zishibhile, azisindi futhi ziyasebenza, futhi zisheshe zaduma emhlabeni wonke kusukela ngo-1997. Kodwa-ke, eminyakeni yamuva nje, izinkomishi zamanzi zepulasitiki ziye zabhekana nokuthengiswa okuvilaphayo okuqhubekayo.Siyini isizathu salesi simo?Ake siqale ngezinzuzo kanye nokubi izinkomishi zamanzi epulasitiki.
Kuyaziwa ukuthi izinkomishi zamanzi zepulasitiki zilula.Njengoba izinto zepulasitiki kulula ukubunjwa, ukuma kwezinkomishi zamanzi epulasitiki kuzoba okomuntu siqu futhi kube nemfashini uma kuqhathaniswa nezinkomishi zamanzi ezenziwe ngezinye izinto.Inqubo yokucutshungulwa kwezinkomishi zamanzi epulasitiki ilula, intengo yezinto ezibonakalayo iphansi, umjikelezo wokucubungula umfushane, isivinini siyashesha, izinga lomkhiqizo elinesici kanye nezinye izizathu kubangela intengo ephansi yezinkomishi zamanzi epulasitiki.Lezi yizinzuzo zezinkomishi zamanzi zepulasitiki.
Kodwa-ke, izinkomishi zamanzi epulasitiki nazo zinamaphutha athile, njengokuqhekeka ngenxa yethonya lemvelo kanye nokushisa kwamanzi, futhi izinkomishi zepulasitiki azimelani nokuwa.Inkinga enkulu kakhulu ukuthi phakathi kwazo zonke izinto zepulasitiki zamanje, aziningi ezingenabungozi ngempela, nakuba izinto eziningi zepulasitiki ziyizinga lokudla, kodwa uma izidingo zokushisa ezibonakalayo sezidlulile, zizoba izinto eziyingozi, njenge-PC ne-AS.Uma izinga lokushisa lamanzi selingaphezu kuka-70°C, okokusebenza kuzokhipha i-bisphenol A, engase yonakalise noma iphule inkomishi yamanzi.Kungenxa yokuthi izinto azikwazi ukuhlangabezana nezidingo zokuphepha zabantu ukuthi izinkomishi zamanzi epulasitiki ngaphandle kwe-tritan ziye zavinjelwa ngokuqinile ukuthi zingene emakethe emakethe yaseYurophu kusukela ngo-2017. Kamuva, imakethe yase-US nayo yaqala ukuphakamisa imithetho efanayo, futhi yanda kakhulu. amazwe nezifunda zaqala ukubeka imingcele ezintweni zepulasitiki.Izinkomishi zamanzi zinezidingo eziphezulu kanye nemikhawulo.Lokhu kudale nokuthi imakethe yenkomishi yamanzi yepulasitiki iqhubeke nokwehla eminyakeni yamuva nje.
Njengoba impucuko yabantu iqhubeka nokuthuthuka kanye nobuchwepheshe buqhubeka nokuqamba izinto ezintsha, kuzozalwa izinto ezintsha zepulasitiki emakethe, njengezinto ze-tritan, eziqashelwe yimakethe yomhlaba wonke eminyakeni yamuva.Lokhu kwasungulwa yi-American Eastman Company futhi kuhloswe ngayo izinto zepulasitiki zendabuko., ezihlala isikhathi eside, ziphephile, zimelana nezinga lokushisa eliphezulu, azinakonakala, futhi azinayo i-bisphenol A. Izinto ezinjengalezi zizoqhubeka nokuthuthukiswa ngokuthuthukiswa kobuchwepheshe, futhi izinkomishi zamanzi zepulasitiki nazo zizosuka komunye umkhombe ziye kwenye isiqongo.
