Ipulasitiki isetshenziswe kabanzi ekuphileni kwethu kwansuku zonke.Kunezinhlobo eziningi zezinto zepulasitiki.Sivame ukuzibona emabhokisini okupakisha epulasitiki, ukugoqa kwepulasitiki, njll. / Imboni yokucubungula ukudla ingenye yezimboni ezisetshenziswa kakhulu emikhiqizweni yepulasitiki, ngoba ukudla kuyimboni esetshenziswa kakhulu.Isondelene nengqikithi yokuphila kwabantu, futhi izinhlobonhlobo zokudla zicebile kakhulu futhi zibanzi, ngakho-ke ziningi izinto ezisetshenziswayo zemikhiqizo yepulasitiki yezinga lokudla, ikakhulukazi emaphaketheni okudla angaphandle.
Ukwethulwa kwezinto zebanga lokudla
I-PET
Ipulasitiki ye-PET ivame ukusetshenziselwa ukwenza amabhodlela epulasitiki, amabhodlela esiphuzo neminye imikhiqizo.Amabhodlela amanzi amaminerali epulasitiki namabhodlela esiphuzo se-carbonated abantu abavame ukuwathenga yonke imikhiqizo yokupakisha ye-PET, okuyizinto zepulasitiki eziphephile ezisezingeni lokudla.
Izingozi zokuphepha ezifihliwe: I-PET ifanelekela kuphela izinga lokushisa legumbi noma iziphuzo ezibandayo, hhayi ukudla okushise ngokweqile.Uma izinga lokushisa lishisa ngokweqile, ibhodlela lizokhipha izinto ezinobuthi ezingase zibangele umdlavuza.Uma ibhodlela le-PET lisetshenziswa isikhathi eside kakhulu, lizokhipha ngokuzenzakalelayo izinto ezinobuthi, ngakho-ke ibhodlela lesiphuzo sepulasitiki kufanele lilahlwe ngokushesha ngemva kokusetshenziswa, futhi akufanele lisetshenziswe ukugcina okunye ukudla isikhathi eside, ukuze lingaphazamisi impilo. .
PP
Ipulasitiki ye-PP ingenye yepulasitiki evamile.Ingenziwa ibe yipulasitiki yanoma yimuphi umkhiqizo, njengezikhwama zepulasitiki ezikhethekile zokudla, amabhokisi epulasitiki okudla, utshani bokudla, izingxenye zepulasitiki zokudla, njll. Iphephile, ayinabo ubuthi futhi inezinga lokushisa elihle eliphansi kanye nezinga lokushisa eliphezulu. ukumelana., i-PP iyona kuphela ipulasitiki engashiswa kuhhavini we-microwave, futhi inokumelana nokugoqa okunamandla aphezulu (izikhathi ezingu-50,000), futhi ngeke yonakaliswe lapho iwa isuka endaweni ephakeme -20 °C.
Izici: Ubulukhuni bungaphansi kwe-OPP, bunganwetshwa (ukunwetshwa kwezindlela ezimbili) bese budonswa kunxantathu, uphawu olungezansi noma uphawu oluseceleni (isikhwama semvilophi), impahla yomphongolo.Ukungafihli kubi kune-OPP
I-HDPE
Ipulasitiki ye-HDPE, eyaziwa ngokuthi i-polyethylene ephezulu-density, inezinga lokushisa eliphakeme lokusebenza, ubulukhuni obungcono, amandla emishini kanye nokumelana namakhemikhali.Yimpahla engenabuthi futhi ephephile futhi ivame ukusetshenziswa ekukhiqizeni iziqukathi zokudla zepulasitiki.Izwakala i-brittle futhi isetshenziselwa kakhulu izikhwama ze-vesti.
Izingozi zokuphepha ezifihliwe: Iziqukathi zepulasitiki ezenziwe nge-HDPE akulula ukuzihlanza, ngakho ukugaywa kabusha akunconyiwe.Kungcono ukuthi ungayifaki kuhhavini ye-microwave.
I-LDPE
Ipulasitiki ye-LDPE, eyaziwa ngokuthi i-low density polyethylene, ithambile uma uyithinta.Imikhiqizo eyenziwe ngayo inezici zokunganambitheki, ezingenaphunga, ezingenabuthi futhi ezibuthuntu.Okuvame ukusetshenziswa ezingxenyeni zepulasitiki zokudla, ifilimu eyinhlanganisela yokupakisha ukudla, ifilimu yokudla, imithi, ukupakishwa kwepulasitiki yezemithi, njll.
Izingozi zokuphepha ezifihlekile: I-LDPE ayikwazi ukumelana nokushisa, futhi ngokuvamile ukuncibilika okushisayo kwenzeka lapho izinga lokushisa lingaphezu kuka-110 °C.Okufana nokuthi: ukugoqa kwepulasitiki kokudla kwasendlini akufanele kugoqe ukudla futhi kushise, ukuze kugwenywe amafutha ekudleni ukuthi angancibiliki kalula izinto eziyingozi ekugoqweni kwepulasitiki.
Ngaphezu kwalokho, indlela yokukhetha izikhwama zepulasitiki ezifanele zokudla?
Okokuqala, izikhwama zepulasitiki zokufaka ukudla azinaphunga futhi azinaphunga lapho ziphuma efektri;izikhwama zepulasitiki ezinamaphunga akhethekile azikwazi ukusetshenziselwa ukubamba ukudla.Okwesibili, izikhwama zepulasitiki ezinemibala (ezifana nobomvu omnyama noma omnyama okwamanje ezisemakethe) azikwazi ukusetshenziselwa izikhwama zepulasitiki zokudla.Ngoba lezi zinhlobo zezikhwama zokupakisha zepulasitiki zivame ukwenziwa ngamapulasitiki agaywe kabusha.Okwesithathu, kungcono ukuthenga izikhwama zepulasitiki zokudla ezitolo ezinkulu, hhayi ezitaladini, ngoba ukuhlinzekwa kwezimpahla akuqinisekisiwe.
