Impi phakathi kwamabhodlela engilazi namabhodlela epulasitiki yinde isikhathi eside, ethathe iminyaka engaphezu kuka-60.Ngokuphikisana kwemvelo, izinzuzo zezempilo nomthelela wokunambitha okufanele ucatshangelwe, kungaba nzima ukukhetha owinile ocacile.Kodwa iyiphi inketho engcono?Ake sikhanyise ngezinye zezinto ezibalulekile kuleli cala.
Izinto okufanele zicatshangelwe
Ngokwethulwa komphakathi kwamabhodlela epulasitiki athengekayo kusukela ngeminyaka yawo-1960, ukuncishiswa kokukhiqizwa kwamabhodlela engilazi bekugqamile.Lokhu kungenxa yokungenzeki kokuphuka, izindleko eziphansi zokukhiqiza kanye nemvelo engasindi yamabhodlela epulasitiki.Uma kuqhathaniswa nozakwabo bezingilazi, lokhu kwenza amabhodlela epulasitiki adume kakhulu.
Nokho, muva nje, kugxilwe ezicini eziyingozi zamabhodlela epulasitiki.Ngokukhathazeka kwamakhemikhali ayingozi afihliwe njenge-BPA, kanye nezingozi ezisanda kutholwa zokushiya amabhodlela epulasitiki elangeni, umbono ophelele wamabhodlela epulasitiki awunawo oqondile.Ngenkathi izinto eziningi ezisetshenziswa epulasitiki manje sezikhululekile i-BPA, ezinye izinto ezilimazayo zingase zibe khona ezingakambulwa.
Ngaphandle kwezingozi zamakhemikhali, esinye isici esingesihle kungaba umonakalo owenziwa amabhodlela epulasitiki endaweni ezungezile.Ngo-2016, kwathengiswa amabhodlela okuphuza epulasitiki angaphezu kwezigidigidi ezingama-480 emhlabeni wonke, okudumazayo kuphela okungaphansi kwama-50% alawo mabhodlela aphinde agaywa kabusha.Ukungcola okukhiqizwayo, ukuntuleka kokugaywa kabusha kanye nokulahlwa okungalungile kwamabhodlela epulasitiki kubangela ukulimala, ngisho nokufa, ezilwaneni zasendle nasezimpilweni zasolwandle.Lezi zonke izici lapho imvelo iba yisisulu sokuzitika ngamabhodlela epulasitiki esintu.
Akucaci kahle
Kodwa ingabe ingilazi ingcono?Akuzona nje izinzuzo zezempilo ezinikezwa ngamabhodlela engilazi, namanzi ahlungiwe ahlala ehlanzekile ngaphandle kwengozi yamanzi angcolile ngamakhemikhali.Ukuwashwa nokuvalwa inzalo kwamabhodlela engilazi ngokuvamile kusebenza kangcono kunalawo amabhodlela epulasitiki.Ukuvumelana okuvamile ukuthi ingilazi iyimpahla engcono yemvelo, kanye nemizimba yethu futhi.Kodwa zisekhona izingozi zemikhiqizo, ngengilazi ephukile kanye nokuphuka kalula okunomthelela obonakalayo emalini yenzuzo yenkampani uma ukukhiqizwa kuyisilinganiso esikhulu.
Ukukhiqizwa kwamabhodlela engilazi kudala ukukhishwa kwekhabhoni, akufani nalawo akhiqizwa amabhodlela epulasitiki.Kukhona futhi isici esiyisisekelo sokuthi akuzona zonke izingilazi, njengepulasitiki, ezingasebenza kabusha.Lokhu kusho ukuthi izinga lokugaywa kabusha alanele futhi uma liqhathaniswa nomonakalo wokukhiqiza.
Ekugcineni womabili amabhodlela engilazi nawepulasitiki anamaphutha ezempilo nawemvelo, kodwa lokho akusho ukuthi awanakho ukufaneleka kwawo.Ucabangani?Ingabe ipulasitiki ingcono kunengilazi?Noma ingabe impumelelo yamabhodlela epulasitiki isazobonakala?Ukukhiqizwa kwamabhodlela engilazi kudala ukukhishwa kwekhabhoni, okungafani nalawo akhiqizwa amabhodlela epulasitiki.Kukhona futhi isici esiyisisekelo sokuthi akuzona zonke izingilazi, njengepulasitiki, ezingasebenza kabusha.Lokhu kusho ukuthi izinga lokugaywa kabusha alanele futhi uma liqhathaniswa nomonakalo wokukhiqiza.
Ekugcineni womabili amabhodlela engilazi nawepulasitiki anamaphutha ezempilo nawemvelo, kodwa lokho akusho ukuthi awanakho ukufaneleka kwawo.Ucabangani?Ingabe ipulasitiki ingcono kunengilazi?Noma ingabe impumelelo yamabhodlela epulasitiki isazobonakala?
Futhi phakathi kwensimbi, ipulasitiki nengilazi, yikuphi okungcono kakhulu?Iqiniso lendaba ukuthi kukhona okuhle nokubi ukuba ngumnikazi ngamunye.
1, Amabhodlela ensimbi engagqwali anenani lezinto ezinhle nezimbi.Ngokuvamile, ahlala isikhathi eside kunengilazi noma ipulasitiki ngenxa yokuthi awakwazi ukumelana nokugqwala, futhi awashintshi amakhemikhali lapho echayeke elangeni/ekushisa.Ngokuvamile zibiza kakhulu kunepulasitiki, njengoba izindleko zokuzikhiqiza ziphezulu kakhulu ngenxa yokudinga amandla.Nokho, insimbi engagqwali ingaphinda igaywe kabusha ngamaphesenti ayi-100.Inketho engcono kakhulu yokukhetha amabhodlela ensimbi engagqwali yibanga lokudla #304 noma 18/8, okusho ukuthi kukhona amaphesenti angu-18 e-chromium namaphesenti angu-8 nickel.Ulwazi olwengeziwe amabhodlela ensimbi engagqwali kungabakutholakala ku-inthanethi.
2, Ingilazi ingenye inketho lapho ukhethaingilaziamabhodlela.Iningi lethu liyazi ukuthi cishe zonke iziphuzo zinambitheka kangcono ebhodleleni lengilazi noma enkomishini, kodwa okubi ukuthi ziphuka futhi mancane amathuba okuthi zihlale isikhathi eside uma ziqhathaniswa nepulasitiki noma insimbi engagqwali.Ngaphezu kwalokho, izinga lokugaywa kabusha liphansi futhi ezinye izindawo zomphakathi aziyivumeli ingilazi nayo.Kodwa-ke, ngaphezu kokunambitha ingilazi enkulu ayivuki lapho ishiywe elangeni / ukushisa, kodwa izindleko zebhodlela lengilazi ngokuvamile ziphakeme kakhulu kunezinye izinketho zethu ezimbili.
3, Ipulasitiki ibonakala iyibhodlela elisebenziseka kabusha elithandwa kakhulu, nakuba ingilazi ne-stainless zithola ukuthandwa ngenxa yezizathu ezibalwe lapha.Amabhodlela epulasitiki ishibhile ukukhiqiza kunensimbi engagqwali nengilazi, okuwenza akhange kakhulu kubathengi.Kodwa-ke, izinga lokugaywa kabusha kwamanye amapulasitiki liphansi futhi nemijikelezo yokuphila mifushane futhi.Amabhodlela epulasitiki avame ukuphelela ezindaweni zokulahla imfucumfucu futhi angathatha iminyaka ecishe ibe ngu-700 ngaphambi kokuba aqale ukubola.Enye yezinto ezimbi kakhulu ezithinta amabhodlela epulasitiki ukuthi ayacwila, kuyilapho ingilazi nensimbi engagqwali akwenzi.Abanye abakhiqizi bamabhodlela asebenziseka kabusha bakhiqiza imikhiqizo ngaphandle kwaleli khemikhali futhi ngokuvamile bayakuqaphela lokho kumalebula noma entweni ngokwayo.Ngaphezu kwalokho, amapulasitiki enziwe nge-BPA ngokuvamile azoba nekhodi ye-resin engu-7 evela entweni.
