Imikhiqizo yepulasitiki ivame kakhulu ezimpilweni zethu zansuku zonke, njengezinkomishi zepulasitiki, i-tableware yepulasitiki, njll. Lapho uthenga noma sisebenzisa le mikhiqizo, sivame ukubona uphawu lukanxantathu oluphrintiwe phansi olunenombolo noma uhlamvu olumakwe kuyo.Kusho ukuthini lokhu?Uzochazelwa ngokuningiliziwe ngezansi.
Lolu phawu lukanxantathu, olwaziwa njengophawu lokugaywa kabusha, lusitshela ukuthi into yepulasitiki yenziwe ngani futhi lubonisa ukuthi into ingaphinda igaywe kabusha.Singasho izinto ezisetshenziswayo kanye nokugaywa kabusha komkhiqizo ngokubheka izinombolo noma izinhlamvu ezingezansi.Ngokuqondile:
Inombolo 1: I-polyethylene (PE).Ngokuvamile kusetshenziselwa ukwenza izikhwama zokupakisha ukudla namabhodlela epulasitiki.Iyasebenziseka kabusha.
Inombolo 2: I-polyethylene ephezulu kakhulu (i-HDPE).Ngokuvamile kusetshenziswa ukwenza amabhodlela okokuhlanza, amabhodlela e-shampoo, amabhodlela ezingane, njll. Angaphinda asetshenziswe.
Inombolo 3: I-Chlorinated polyvinyl chloride (PVC).Ngokuvamile esetshenziselwa ukwenza iziphanyeko, phansi, amathoyizi, njll. Akulula ukuvuselela futhi ukukhipha kalula izinto eziyingozi, eziyingozi emvelweni nempilo yomuntu.
Inombolo 4: I-polyethylene ephansi (LDPE).Ivamise ukusetshenziselwa ukwenza izikhwama zokudla, izikhwama zikadoti, njll. Igaywa kabusha.
Inombolo 5: I-Polypropylene (PP).Ngokuvamile kusetshenziselwa ukwenza amabhokisi ka-ayisikhilimu, amabhodlela e-soy sauce, njll.
No. 6: I-Polystyrene (IHU).Ngokuvamile kusetshenziselwa ukwenza amabhokisi esidlo sasemini egwebu, izinkomishi ze-thermos, njll. Akulula ukugaywa kabusha futhi kukhiphe kalula izinto eziyingozi, eziyingozi emvelweni nempilo yabantu.
No. 7: Ezinye izinhlobo zamapulasitiki, njenge-PC, i-ABS, i-PMMA, njll. Ukusetshenziswa kwempahla nokugaywa kabusha kuyahlukahluka.
Kumele kuqashelwe ukuthi nakuba lezi zinto zepulasitiki zingaphinda zisetshenziswe futhi zisetshenziswe kabusha, ekusebenzeni kwangempela, ngenxa yezinye izithako ezingezwe emikhiqizweni eminingi yepulasitiki, akuwona wonke amamaki aphansi amele u-100% wokuvuselela kabusha.Isimo esithile Kubuye kuncike kuzinqubomgomo zendawo zokuphinda zisetshenziswe kanye namandla okucubungula.
Ngamafuphi, lapho uthenga noma sisebenzisa imikhiqizo yepulasitiki efana nezinkomishi zamanzi zepulasitiki, kufanele sinake izimpawu zokugaywa kabusha ezingaphansi kwazo, sikhethe imikhiqizo eyenziwe ngezinto ezigaywa kabusha, futhi ngesikhathi esifanayo, sihlele futhi sigaywe kabusha ngangokunokwenzeka ngemva kwalokho. sebenzisa ukuvikela imvelo.
