Amapulasitiki asetshenziswe kabanzi empilweni yethu yansuku zonke. Kunezinhlobo eziningi zezinto zepulasitiki. Imvamisa sibabona emabhokisini okufaka epulasitiki, ukugoqa kwepulasitiki, njll. Imboni yokusebenza kokudla ingenye yezimboni ezisetshenziswa kakhulu zemikhiqizo yepulasitiki, ngoba ukudla kungumkhakha osetshenziswa kakhulu. Kusondele entweni yempilo yabantu, futhi izinhlobonhlobo zokudla zicebile kakhulu futhi zibanzi, ngakho-ke kunezicelo eziningi zemikhiqizo yepulasitiki yebanga lokudla, ikakhulukazi ezakhiweni zangaphandle zokudla.
Ukwethulwa kwezinto zokwakha ibanga lokudla
Thinta ngothando
Ipulasitiki yezilwane ezifuywayo ivame ukusetshenziselwa ukwenza amabhodlela epulasitiki, amabhodlela ophuzo neminye imikhiqizo. Amabhodlela amanzi amaminerali amaminerali namabhodlela kadokotela we-carbonated abantu abavame ukuthenga kuwo wonke imikhiqizo yokupakisha yezilwane, okuyizinto zepulasitiki eziphephile zokudla.
Izingozi Ezifihliwe Zokuphepha: I-Pet ilungele kuphela izinga lokushisa lekamelo noma iziphuzo ezibandayo, hhayi ukudla okushiywe ngokweqile. Uma izinga lokushisa ligcwele ngokweqile, ibhodlela lizokhipha izinto ezinobuthi ezingadala umdlavuza. Uma ibhodlela lezilwane ezifuywayo lisetshenziselwa isikhathi eside kakhulu, lizokhipha ngokuzenzakalelayo izinto ezinobuthi, ngakho-ke ibhodlela lesiphuzo sepulasitiki kufanele liphonswe ngokushesha ngemuva kokusebenzisa, futhi akufanele lisetshenziselwe ukugcina okunye ukudla isikhathi eside, ukuze kungathinti impilo.
PP
I-PP Plastic ngenye yamapulasitiki ajwayelekile kakhulu. Kungenziwa ngepakishi yepulasitiki yanoma yimuphi umkhiqizo, njengezikhwama ezikhethekile zepulasitiki zokudla, amabhokisi epulasitiki wokudla, izingxenye zokudla, izingxenye zepulasitiki zokudla, njll. Kuphephile izinga lokushisa eliphansi kanye nokumelana okuphezulu. , I-PP ukuphela kwepulasitiki engafudunyezwa kuhhavini we-microwave, futhi inokuphikiswa okunamandla okuqinisa amandla (amahlandla angama-50 000), futhi ngeke ilinyazwe lapho iwela endaweni ephakeme ku-20 ° C.
Izici: Ubulukhuni bungaphansi kwe-OPP, bungalulwa (ukwelula izindlela ezimbili) bese udonsa unxantathu, uphawu olungezansi noma esisezingeni eliseceleni (eMvivope. Ukusobala kubi kakhulu kune-opp
Hdpe
I-HDPE Plastic, eyaziwa kakhulu ngokuthi i-polyethylene ephezulu, inokushisa okuphezulu okusebenzayo, ubunzima obungcono, amandla emishini kanye nokumelana kwamakhemikhali. Kuyinto engabangeli-anobuthi futhi ephephile futhi imvamisa isetshenziswa ekukhiqizweni kweziqukathi zokudla zepulasitiki. Izwa i-brittle futhi isetshenziselwa kakhulu izikhwama ze-vest.
Izingozi Ezifihliwe Zokuphepha: Iziqukathi zepulasitiki ezenziwe nge-HDPE akulula ukuzihlanza, ngakho-ke ukusebenzisa kabusha akunconywa. Kuhle ukungakufaki ku-microwave.
I-LDPE
I-LDPE Plastic, eyaziwa kakhulu njenge-polyethylene ephansi, ithambile ngokuthinta. Imikhiqizo eyenziwe ngayo inezici zobuntu obungenabutha, obungenakuphunga, abangabuthathi kanye nobudlova. Evame ukusetshenziswa ezingxenyeni zepulasitiki zokudla, ifilimu eliyinhlanganisela yokufaka ukudla, ifilimu lokupheka, umuthi, ukuhlanganiswa kwepulasitiki kwemithi, njll.
Izingozi Zokuphepha Ezifihliwe: I-LDPE akuyona ukumelana nokushisa, futhi imvamisa kuncibilike ukuncibilika lapho izinga lokushisa lidlula ngo-110 ° C. Njengoku: Ukugoqwa kwepulasitiki ekhaya akufanele kusonge ukudla futhi kushise, ukuze kugwenywe amanoni ekudleni okuvela kalula ezintweni eziyingozi esongelweni sepulasitiki.
Ngaphezu kwalokho, ungazikhetha kanjani izikhwama zepulasitiki ezilungile zokudla?
Okokuqala, izikhwama zokupakisha zepulasitiki zokudla zingenaphunga futhi zingenampula lapho zishiya ifektri; Izikhwama zokupakisha zepulasitiki ezinamaphunga akhethekile azikwazi ukusetshenziselwa ukubamba ukudla. Okwesibili, izikhwama ezihlanganisiwe zeplastiki zepulasitiki (ezifana nobomvu obumnyama noma omnyama njengamanje emakethe) azikwazi ukusetshenziselwa izikhwama zepulasitiki zokudla. Ngoba lezi zinhlobo zezikhwama zokupakisha zepulasitiki zivame ukwenziwa ngemfucuza eyenziwe kabusha. Okwesithathu, kungcono ukuthenga izikhwama zepulasitiki zokudla ezitolo ezinkulu zezitolo, hhayi izitebele zasemgwaqweni, ngoba ukuhanjiswa kwezimpahla akuqinisekisiwe.
