Kutheni i-HDPE inamandla kangaka?
Uxelelwa ukuba uthembele kwi-HDPE, kodwa ifana neplastiki. Kunzima ukukholelwa ukuba inokuba namandla njengezinto zemveli, nto leyo ekwenza ungaqinisekanga ukuyichaza kwimisebenzi ebalulekileyo.
I-HDPE inamandla kakhulu ngenxa yesakhiwo sayo se-molecular esiqinileyo nesithe nkqo. Ngexesha lokwenziwa kwayo, imixokelelwane emide ye-polyethylene yenziwa ngamasebe ambalwa kakhulu, nto leyo evumela ukuba ipakishwe ngokusondeleyo. Oku kudala izinto ezixineneyo, ezikristale eziqinileyo neziqinileyo kakhulu.
Igama elithi “High-Density Polyethylene” likuxelela yonke into. “High-Density” yimfihlelo yamandla ayo. Cinga ngayo njengokupakisha isutikheyisi. Ukuba uphosa nje impahla, kukho indawo eninzi engenanto. Kodwa ukuba uyisonga kakuhle, ungangena eninzi. Iimolekyuli ezikwiHDPE zifana neempahla ezisongwe kakuhle; zipakishwa ndawonye ngokuqinileyo. Okuisakhiwo esiqinileyokwenza kube nzima kakhulu ukuba iikhemikhali zingene okanye ukuba iimpembelelo zibangele ukwaphuka. Ngokwahlukileyo koko, iLow-Density Polyethylene (LDPE) ineemolekyuli ezinamasebe ezifana neempahla eziqhekekileyo—azinakupakisha kakuhle, ngoko ke izinto zithambile kwaye zibuthathaka. Njengomvelisi, ndiyazi ukuba umgangatho wombhobho wokugqibela umiselwa ngumgangatho wesi sakhiwo semolekyuli kwi-resin eluhlaza. Yiyo loo nto sifumana kuphelai-resin ye-PE100 esemgangathweni ophezulu, engasebenzi kakuhle.

Ngaba i-HDPE inamandla kuneplastiki?
Igama elithi “iplastiki” lidla ngokuvakala libuthathaka okanye lingasetyenziswa. Uxhalabile kukuba ukusebenzisa umbhobho we-HDPE kukunciphisa amandla kunye nobude bexesha. Oku kungaqondani kunokubangela ukuba ukhethe izinto ezinzima nezibiza kakhulu.
Oku kukudideka okuqhelekileyo, kuba i-HDPEisuhlobo lweplastiki. Nangona kunjalo, yiplastiki yodidi lobunjineli enamandla kakhulu kune "iiplastiki" ezisetyenziswa ngokubanzi. Xa kuthelekiswa nezinto ezisetyenziselwa ukupakisha okanye izinto zasekhaya, i-HDPE yomelele kakhulu, ihlala ixesha elide, kwaye yenzelwe ukusetyenziswa kakhulu.
Ukuthi “iplastiki” kufana nokuthi “isinyithi.” Itini yealuminiyam kunye nomqadi wentsimbi zombini ziyintsimbi, kodwa zinamandla ahlukeneyo kunye nokusetyenziswa kwazo. Kuyafana nangeplastiki. Iplastiki ekwibhotile yamanzi elahlwayo (i-PET) ayifani neplastiki ekwibhampa yemoto yakho (idla ngokuba yi-Polypropylene blend), engafaniyo neplastiki ekwisixhobo samanzi esinoxinzelelo oluphezulu (i-HDPE). I-HDPE iwela kudidi lwe- “i-thermoplastics yobunjineli"Ezi zizinto ezenzelwe ngokukodwa ukujongana noxinzelelo loomatshini, uxinzelelo oluphezulu, kunye neendawo ezinzima ixesha elide. Xa umphathi wokuthenga ofana no-Arief echaza umbhobho, akathengi nje "iplastiki"; ukhetha izinto ezenziwe ngobuchule obuphezulu ezineempawu zokusebenza eziqinisekisiweyo ezikhuphisana okanye ezidlula izinto zemveli ezifana nekhonkrithi okanye isinyithi esithambileyo kwizicelo ezininzi.
