Kuze kube manje, cishe kunezinhlobo eziyikhulu ezaziwayo zezinto zepulasitiki.
Kunamapulasitiki ayisikhombisa asetshenziswa kakhulu, okungukuthi:
1. I-polyethylene terephthalate pet
Isibonelo: Amabhodlela amanzi amaminerali, amabhodlela e-carbonated beverage
Ukusetshenziswa: Ukuvimbela ukushisa kuya ku-70 ℃, kufanelekile kuphela iziphuzo ezifudumele noma eziqandisiwe; Ama-liquid aphezulu okushisa noma ukufudumeza kungadala ukonakala futhi akhulule izinto eziyingozi emzimbeni womuntu.
2. I-Polyethylene ephezulu - HDPE
Isibonelo: Imikhiqizo yokuhlanza, imikhiqizo yokugeza.
Ukusetshenziswa: Kungasetshenziswa kabusha ngemuva kokuhlanza ngokucophelela, kepha lezi ziqukathi zivame ukuba nzima ukuzihlanza futhi zishiye imikhiqizo yokuhlanza eyayiyinqabile, ukuba yindawo yokuzalela yamagciwane. Kungcono ukungazisebenzisi kabusha.
3. I-Polyvinyl Chloride - PVC
Isibonelo, ezinye izinto zokuhlobisa.
Ukusetshenziswa: Lokhu okubonakalayo kuthambekele ekukhiqizeni izinto eziyingozi emazingeni okushisa aphezulu. Uma isetshenzisiwe, ungavumeli ukuthi kufutheke.
4. I-Low density polyethylene - ldpe
Isibonelo: cling ifilimu, ifilimu yepulasitiki, njll.
Ukusetshenziswa: Kuyaphefumula futhi akunakwenzeka, futhi kunamandla okushisa abuthakathaka. Lapho izinga lokushisa lidlula ngo-110 ℃, lizothola ukuncibilika okushisayo, kushiye ngemuva kwamalungiselelo athile epulasitiki angenakubola ngumzimba womuntu.
I-5. I-Polypropylene - PP
Isibonelo: Ibhokisi lesidlo sasemini se-microwave.
Ukusetshenziswa: Leli yibhokisi lepulasitiki kuphela phakathi kwabayisikhombisa elingabekwa kuhhavini we-microwave futhi lingasetshenziswa kabusha ngemuva kokuhlanza.
6. I-Polystyrene - IHu.
Hong kong isitayela isihlangu
Isibonelo: Ibhokisi le-noodle elisheshayo le-noodle, ibhokisi lokudla okusheshayo.
Ukusetshenziswa: Kokubili okuvimbela ukushisa nokubandayo, kepha akunakubekwa kuhhavini we-microwave ukuvimba ukukhishwa kwamakhemikhali ngenxa yamazinga okushisa aphezulu ngenxa yamazinga okushisa aphezulu.
7. Amanye amakhodi epulasitiki - amanye
