Empilweni yethu yansuku zonke, sizohlangana nezikhwama zokufaka zepulasitiki nsuku zonke. Kuyingxenye ebalulekile futhi ebalulekile yokuphila kwethu. Kodwa-ke, bambalwa kakhulu abangani abaziyo ngezinto zezikhwama zokupakisha zepulasitiki. Ngakho-ke uyazi ukuthi yiziphi izinto ezisetshenziswa kakhulu zezikhwama zokupakisha zepulasitiki?
Izinto ezisetshenziswa kakhulu zezikhwama zokupakisha zepulasitiki zimi kanje:
1. Isikhwama sepulasitiki se-PE
I-Polyethylene (PE), efushanisiwe njenge-PE, iyinhlanganisela ephezulu yamangqamuzana eyenziwe ngokuhlanganisa i-polymerization ye-ethylene. Kubhekwa njengento enhle yokuxhumana nokudla emhlabeni. I-Polyethylene ifaka umswakama, ayizweli komoya-mpilo, imelana ne-asidi, imelana ne-alkali, ayinabuthi, ayinambitheki, futhi ayinaphunga. Ihlangabezana nezindinganiso zokuhlanzeka zokupakishwa kokudla futhi yaziwa ngokuthi "imbali yepulasitiki".
2. Isikhwama sepulasitiki se-PO
Ipulasitiki ye-PO (i-polyolefin), efushanisiwe njenge-PO, i-polyolefin copolymer, i-polymer eyenziwe ngama-olefin monomers. Opaque, crisp, non-toxic, ngokuvamile PO izikhwama flat, PO vest izikhwama, ikakhulukazi PO plastic izikhwama.
3. Isikhwama sepulasitiki se-PP
Izikhwama zepulasitiki ze-PP ziyizikhwama zepulasitiki ezenziwe nge-polypropylene. Ngokuvamile basebenzisa izinqubo zokunyathelisa ngombala kanye nezinqubo zokuphrinta ze-offset ezinemibala egqamile. Zingamapulasitiki e-polypropylene anwebekayo futhi ayingxenye yohlobo lwe-thermoplastic. Indawo engeyona enobuthi, ayinambitheki, ebushelelezi futhi esobala.
4. Isikhwama sepulasitiki se-OPP
Izikhwama zepulasitiki ze-OPP zenziwe nge-polypropylene kanye ne-bidirectional polypropylene, ezibonakala ngokushiswa kalula, ukuncibilika nokuconsa, okuphuzi phezulu nokuluhlaza okwesibhakabhaka phansi, intuthu encane ngemva kokushiya umlilo, futhi iqhubeke ivutha. Inezici zokungafihli okuphezulu, ukubola, ukuvala uphawu okuhle, kanye nokuphikisana okuqinile komgunyathi.
5. Isikhwama sepulasitiki se-PPE
Isikhwama sepulasitiki se-PPE siwumkhiqizo okhiqizwa ngokuhlanganisa i-PP ne-PE. Umkhiqizo awungenisi uthuli, awubambisi amagciwane, awufakazi umswakama, uvimbela i-oxidation, ukumelana nezinga lokushisa eliphezulu, ukumelana nezinga lokushisa eliphansi, ukumelana nowoyela, awunobuthi futhi awunaphunga, usobala kakhulu, izakhiwo eziqinile zemishini, kanye ne-anti-blasting Ukusebenza okuphezulu, ukubhoboza okuqinile nokumelana nezinyembezi, njll.
6. Eva plastic isikhwama emaphaketheni
Izikhwama zepulasitiki ze-EVA (izikhwama ezineqhwa) zenziwe ngokuyinhloko ngezinto eziqinile ze-polyethylene nezinto zomugqa, eziqukethe u-10% wempahla ye-EVA. Ukucaca okuhle, umgoqo we-oxygen, umswakama-ubufakazi, ukuphrinta okukhanyayo, umzimba wesikhwama esikhanyayo, ungagqamisa izici zomkhiqizo ngokwawo, ukumelana ne-ozone, i-flame retardant nezinye izici.
7. Isikhwama seplastiki sePVC
Izinto ze-PVC ziqhwa, zisobala, zisobala kakhulu, azihambisani nemvelo futhi ezinobuthi obuphansi, azinabo ubuthi emvelweni (i-6P ayiqukethe ama-phthalates namanye amazinga), njll., kanye nerabha ethambile neqinile. Iphephile futhi ihlanzekile, ihlala isikhathi eside, inhle futhi iyasebenza, inhle ngokubukeka, futhi ihlukene ngezitayela. Kulula kakhulu ukuyisebenzisa. Abakhiqizi abaningi bemikhiqizo esezingeni eliphezulu ngokuvamile bakhetha izikhwama ze-PVC ukuze bazipakishe, bafake kahle imikhiqizo yabo, futhi bathuthukise amamaki abo omkhiqizo.
Okuqukethwe okwethulwe ngenhla ezinye izinto ezivame ukusetshenziswa ezikhwameni zokupakisha zepulasitiki. Lapho ukhetha, ungakhetha izinto ezifanele zokwenza izikhwama zokupakisha zepulasitiki ngokwezidingo zakho zangempela.
