Iziqukathi zokudla zepulasitiki ziyizitsha ezilahlwayo ezenziwe ngepulasitiki, eziklanyelwe ukugcinwa kokudla kwesikhashana -. Ziyizinto zasendlini ezivamile ezisetshenziselwa ukugcina izithelo, ukudla, ukudla okulula nokunye ukudla. Ngezinzuzo ezifana nokuba nesisindo esincane futhi ungajwayele ukuphuka, lezi ziqukathi zokudla zepulasitiki sezidume kakhulu. Kodwa ingabe uyazi ukuthi yini okudingeka uyinake lapho uzisebenzisa?
Izinkathazo Eziyinhloko Zabantu
● Ukufuduka Kwamakhemikhali: Amakhemikhali asezitsheni zokudla zepulasitiki angase athuthele ekudleni, aphazamise ukunambitheka kokudla. Okukhathaza kakhulu ukuthi izinto ezinobuthi neziyingozi zingabeka engcupheni ukuphepha kokudla futhi zilimaze impilo yabantu.
● Izinkinga Zenhlanzeko: Ukungahlanzeki kahle kweziqukathi zokudla zepulasitiki, njengokungcoliswa amagciwane, kungaba nomthelela oqondile empilweni yomuntu.
Izinyathelo Zokuqaphela Ukusebenzisa Iziqukathi Zokudla Zepulasitiki
(1) Thola Amalebula Okubalulekile:
Izitsha zokudla zenziwa ngezinto ezahlukene zepulasitiki. Ngokuvamile, kunophawu lokugaywa kabusha elingunxantathu ngaphansi kwesiqukathi, elinenombolo esuka ku-1 - 7 ngaphakathi. Inombolo ngayinye imelela into ethile yepulasitiki. Isibonelo, inombolo 5 imele i-polypropylene (PP). Lokhu okubalulekile kuphephile uma kuqhathaniswa, kungamelana namazinga okushisa aphakeme, futhi kuvame ukusetshenziselwa iziqukathi zokudla ezingashiswa kuhhavini we-microwave.
(2) Izidingo Zesikhathi Sezinto Ezihlukene
● Izitsha ze-PP: Iziqukathi zokudla zepulasitiki ezenziwe nge-PP zingabekezelela amazinga okushisa aphakeme uma kuqhathaniswa futhi zifanele ukubamba ukudla okushisayo nezitsha.
● Iziqukathi Ze-PS: PS - Iziqukathi zokudla zepulasitiki ziqinile kodwa zijwayele ukuqhekeka. Aqala ukuthamba lapho izinga lokushisa lifinyelela ku-75 degrees . Ngakho-ke, ukudla kufanele kupholiswe izinga lokushisa elilingana negumbi ngaphambi kokufakwa kulezi zitsha. Kodwa-ke, banokusebenza okuhle kakhulu kwezinga lokushisa eliphansi - futhi bafanele ukubamba ukudla okufakwe esiqandisini.
(3) Ukuhambisana Kokudla
Ukudla okunamafutha amaningi kanye noshukela akufanelekile ukufakwa ezitsheni zokudla zepulasitiki. Iphuzu lokubilisa lamafutha lingu-300℃, elingadlula kalula umkhawulo wokumelana nokushisa - wepulasitiki. Ukwengeza, uwoyela, ushukela, ama-plasticizers, nezinye izinto ziyizinhlanganisela eziphilayo. Ngokomgomo othi "njengokuncibilika njengokufana," zingase zisabele ngamakhemikhali nalezi zitsha zokudla.
(4) Gwema Ukusebenzisa Kabusha
Iziqukathi zokudla zepulasitiki ezilahlwayo zidizayinelwe ukusetshenziswa - kanye. Ukuphinda uwasebenzise kungabangela ukuba iziqukathi ziguge futhi ziguge, okwandisa ingozi yokukhishwa kwezinto eziyingozi. Ngaphezu kwalokho, lapho uhlanza iziqukathi, okokuhlanza kungase kuhlale phezu kwazo, kuqhubeke kungcolise ukudla.Ukukhishwa Kwezinto Ezingamakhemikhali.
(5) Ukukhishwa Kwezinto Zamakhemikhali
Uma usebenzisa iziqukathi zokudla zepulasitiki ezilahlwayo, qaphela ukucwiliswa kwamakhemikhali okungenzeka. Lokhu kungenzeka lapho ushisisa ukudla, ugcina ukudla okunamafutha noma okune-acidic. Kulezi zimo, ipulasitiki ingase ikhiphe amakhemikhali ekudleni, ikakhulukazi lapho ithinta ukushisa, uwoyela, noma izinto ezine-asidi. Lena inkinga ebaluleke nakakhulu yeziqukathi ezindala noma ezilimele.
I-Yangrui Ikunikeza Iziqukathi Zokudla Zepulasitiki Eziphephile Ezilahlwayo!
Isungulwe ngo-2014, ikomkhulu lethu liseSifundazweni saseGuangdong. Sinesikhungo sokukhiqiza esihlanganisa indawo engamamitha-skwele ayi-14,400, esifakwe imigqa yokukhiqiza engu-15. Siphinde sazuza ukukhiqizwa kwedijithali efektri yokuqala ngohlelo lwe-MES, ngomthamo wokukhiqiza wanyanga zonke wamathani angaphezu kuka-2,000. Ngesipiliyoni seminyaka engaphezu kwengu-11, sihlala sikwazi ukukunikeza - iziqukathi zokudla zepulasitiki zekhwalithi ephezulu.
