Ungakwazi yiniukushisa shwabanisa i-polyethylene?I-Polyethylene (PE) iyi-polymer ye-thermoplastic eguquguqukayo evame ukusetshenziswa ezimbonini ezahlukahlukene ngenxa yezakhiwo zayo ezinhle kakhulu zokusebenza kanye nokumelana namakhemikhali.Ibuye isetshenziswe kabanzi ezinhlelweni zokupakisha, njengoba iqinile, iguquguquka, futhi isobala.Enye indlela edumile yokupakisha nge-PE ukusebenzisaPE ukushisa ifilimu shrinkable.
PE ukushisa ifilimu shrinkablewuhlobo lwefilimu lokupakisha elingashwabana liqine eduze komkhiqizo lapho kufakwa ukushisa.Le filimu ikhiqizwa kusetshenziswa inqubo ekhethekile ebandakanya ukukhipha inhlaka ye-PE ibe yifilimu bese iqondisa ama-molecule efilimu ukuze kwakhiwe into yokupakisha eqinile nehlala isikhathi eside.Uma ishiswa ezingeni lokushisa elithile, ngokuvamile eliphakathi kuka-120°C no-160°C, ifilimu iyashwabana futhi ihambisane ngokuqinile nokuma komkhiqizo.
Ngakho-ke, impendulo yombuzo othi, "Ungakwazi yini ukushisa i-polyethylene yokunciphisa?"unguyebo oqinisekile.I-PE iyimpahla ye-thermoplastic, okusho ukuthi ingashiswa futhi yenziwe kabusha izikhathi eziningi ngaphandle kokwenza izinguquko ezibalulekile ekwakhekeni kwamakhemikhali.Lesi sakhiwo sivumela ukuthi ukushisa kunciphe kalula, okwenza kube impahla efanelekile yokupakisha izinhlelo zokusebenza.
Inqubo yokunciphisa ukushisa inikeza izinzuzo eziningana.Okokuqala, inikeza ukupakishwa okuqinile nokuvikelekile komkhiqizo, ukuwuvikela kumswakama, uthuli, nokunye ukungcola.Iphinde ithuthukise ubuhle bomkhiqizo, iwunikeze ukubukeka okuhlanzekile nobungcweti.Ngaphezu kwalokho, amaphakheji angancipha ukushisa ayabonakala, njengoba noma yimuphi umzamo wokuvula iphakheji uzobonakala.
Ifilimu ye-PE encipha ukushisa isetshenziswa kabanzi ezimbonini ezahlukahlukene, okubandakanya ukudla nesiphuzo, ezemithi, izinto zikagesi, nezimpahla zabathengi.Ingasetshenziselwa ukupakisha imikhiqizo ngayinye, ukudala amaphakethe amaningi noma ukuhlanganisa imikhiqizo ndawonye.Ukuguquguquka kwefilimu yokunciphisa ukushisa kuvumela ukuthi isetshenziselwe izimo ezihlukahlukene zomkhiqizo nosayizi, okwenza kube ukukhetha okuthandwayo kubakhiqizi abaningi.
Sengiphetha, i-polyethylene ingancipha ngempela ukushisa kusetshenziswa ifilimu ye-PE eshwabene.Le ndlela yokupakisha inikeza izinzuzo eziningi, okuhlanganisa ukuvikelwa komkhiqizo, ubuhle obuthuthukisiwe, kanye nobufakazi bokuphazamisa.Ifilimu ye-PE eshrinkable ukushisa iyinto yokupakisha eguquguqukayo futhi esetshenziswa kabanzi ezimbonini ezahlukahlukene.
