Xa kuziwa kwiifilimu zeplastiki, zimbini iinketho ezidumileyo kwimarike:HDPE(I-Polyethylene yoxinzelelo oluphezulu) kunyeI-LDPE(I-Polyethylene yoXinano oluphantsi).Zombini ezi zixhobo zidla ngokusetyenziswa ekupakisheni, kwezolimo nakumashishini okwakha.Nangona kunjalo, abathengi abaninzi kunye namashishini bahlala bezibuza ukuba yeyiphi engcono phakathi kwe-HDPE kunye ne-LDPE.Kweli nqaku, siza kuphonononga umahluko phakathi kwezi zixhobo zimbini kwaye sixoxe ngezinto eziluncedo nezingeloncedo ngazo.
Okokuqala, makhe sijonge kwi-LDPE.I-LDPE yimathiriyeli ebhetyebhetye nekhaphukhaphu edla ngokusetyenziswa ekwenzeni iifilim zeplastiki ezibhityileyo nezizolukileyo.I-LDPE isoloko isetyenziselwa iinjongo zokupakisha, ezifana nokuvelisa iingxowa zeplastiki, ukushwabana okusongayo, kunye neefilimu zezolimo.I-LDPE iyaziwa ngokuxhathisa okugqwesileyo kumswakama kunye neekhemikhali, okwenza ukuba ifaneleke kwizicelo ezifuna umgangatho ophezulu wokuguquguquka kunye nokuqina.Abavelisi befilimu beLDPE bahlala bevelisa uluhlu olubanzi lweemveliso ukuhlangabezana neemfuno ezahlukeneyo zabathengi babo.
Kwelinye icala, i-HDPE yimathiriyeli exineneyo kwaye yomelele xa ithelekiswa ne-LDPE.I-HDPE isetyenziswa ngokuqhelekileyo kwizicelo ezifuna iifilimu zeplastiki eziqinileyo kunye nezihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala khona.Ifilimu yeplastiki ye-HDPEiyaziwa ngamandla ayo agqwesileyo okuqina kunye nokumelana neekhemikhali, iyenza ibe lolona khetho lufanelekileyo kwizicelo zangaphandle kunye nezinzima.Abavelisi befilimu ye-HDPEukuvelisa uluhlu olubanzi lweemveliso ezilungiselela izicelo zoshishino kunye nezorhwebo.
Ngoku, makhe sithelekise ezi zinto zimbini ngokweempawu zazo kunye neempawu zazo.I-LDPE iyaziwa ngokuguquguquka kwayo kunye no-elasticity, okwenza ukuba ilungele izicelo ezifuna ukunwebeka kunye nokuhambelana neemveliso ezipakishwayo.Ngakolunye uhlangothi, i-HDPE iyaziwa ngokuba lukhuni kunye nokuqina kwayo, okwenza ukuba ilungele izicelo ezifuna amandla kunye nokuqina.Xa kuziwa ekuchaseni iikhemikhali, zombini i-LDPE kunye ne-HDPE zibonisa ukuchasana okulungileyo kumswakama kunye neekhemikhali, zibenza zilungele ukupakishwa kunye nezicelo zokuqulatha.
Ngokwempembelelo yokusingqongileyo, zombini i-LDPE kunye ne-HDPE zizixhobo ezinokuphinda zisetyenziswe.Nangona kunjalo, i-HDPE ikholisa ukuvunywa ukuba isetyenziswe kwakhona kwiindawo ezininzi xa kuthelekiswa ne-LDPE.Oku kungenxa yokuba i-HDPE inexabiso eliphezulu kwimarike yokurisayikilisha ngenxa yokuqina kwayo kunye neempawu ezingqongqo.Ngenxa yoko, i-HDPE ihlala ithandwa ngabaxhasi bemekobume kunye nabathengi abanozinzo.
Ukuqukumbela, ukhetho phakathi kwe-HDPE kunye ne-LDPE ekugqibeleni luxhomekeke kwiimfuno ezithile kunye nokusetyenziswa komsebenzisi.I-LDPE ifanelekile kwizicelo ezifuna ukuguquguquka kunye nokwelula, ngelixa i-HDPE ifanelekile kwizicelo ezifuna ukuqina kunye namandla.Zombini izixhobo zineseti yazo yoncedo kunye nezinto ezingeloncedo, kwaye kubalulekile ukuba amashishini kunye nabathengi babonisane ne-LDPE kunyeAbavelisi befilimu zeplastiki ze-HDPEukumisela eyona mathiriyeli ilungileyo kwiimfuno zabo ezithile.Ekugqibeleni, zombini ezi zixhobo zidlala indima ebalulekileyo ekuhlangabezaneni neemfuno ezahlukeneyo zokupakisha, ezolimo, nemizi-mveliso yokwakha.
