Ukwenza uphi indlela yokuzenza ukuba uyazi ukuthi yini imifanelo esethwelene nalokusha sasetyenziswa esezantsi? Bayasetshenziswa ngokuhlu kanye nezinto ezinikezeli, njengamanjezi apho sihlola, amabhokisi olwandle, amabhokisi abadwa basekhululo, kunye nenkinga lezi zinto. Ngonyaka yokuqala kwiimifanelo emithathu ephambili, u-PE ungenziwe ngokusebenzela ipolietileni, ifanele yesiphumo esingabhedlise ekutsi ethylene molecules. Amamolekuli amaningi akhona amabhedlisi aziphumelela ukufika kumanyelo omncane okanye ukufika kumanyelo olunye ukufunda iphlastiki sisetshenziswa ngokuhlu kulesi sikhatsi.
I-PE ifakwa ngamabhedhalo emithathu evulekileyo, i-LDPE, i-HDPE kunye nesi-LLDPE. Zonke izinhlobo zihlala ngezindawo ezikhona njengesimono esishayeleleyo kwaye zihamba ngezindlela eziningi. Ngokushesha, “i-LDPE yehlula ngokuthi yinkqubo yepolyethileni yenkambizo kunye nokuthi ukhuphe kakhulu okanye ungenziwe ngokukhulu phakathi kwabantu abaningi. I-HDPE, okanye ipolyethileni yenkambizo enkulu, uyavamile kunye nokuhuphe kakhulu. Ngakwesikhashana, i-LLDPE iyipolyethileni elinye lenkambizo elenkulu kunye nokuthi ungene amandla ekubhekweni kwe-LDPE kunye ne-HDPE. Ngokuziphumelela kwezindlela zakhe, zonke izinhlobo ze-PE zisetyenziswa ngemibono apho luchunge.
Umbono okuningi lwePE plastic ngokuba kufanelelwa. Ngakwesokuqondeni, ukufanelwa kufanelelwa ngoba yinto engavumelekileyo lokuhlola ilizwe lethu. Lolu hlobo lwesimo lifanele ukuba lisebenzise ukuze lize kuhlanganiswe ukusetha amagama etusha ngenkathi sifanelwa. Ukuphela kokuthatha izixhobo zokubheka nokugcina indlela yokuthi zingene zokusebenza emva kokuthi zihlanganiswe, kunye neziqhutywa ezinomsindo, ezintaba, kunye nezilimo ezikhulu zokudla, amakhompiyoni angaphambili abasebenzisa amagama ahlawulayo apho afanelelwa. Lokhu kungcono lokuhlola umhlaba wethu!
Siyaziqa LDPE kunye noHDPE oya ezimbini zezilimi ezidingekileyo zePE plastic. LEDE iye ngasemva kancane kunye nokungangiphe futhi kancane kulandelana noHDPE. Le ndlela engeziyo yilo hlobo elibonakalayo leyiyo yisimo esigodleni sokuthi LEDE yiyo umthombo omkhulu lokusebenza kumagama amacayishoni weplastiki kunye nezincwaliso zokudla, eziphathelene ukuthi zidliwe kanye nokuthi aziphumelele. Ngakwesoku HDPE iyinye inqanawa kunye nokungabhedele. Le ncwangciso ifanele ukuthi isebenze kumagama amaqhutywa angene angeneyo ukuthi aziqhamuka, njengemphoyiso wesiqhutyu kunye nemiphoyiso weplastiki.
Kunezukuphi lalokho amathophu ane amaphethuzi ahlukene kwePE. Ukuba kushona ngasinye ukusuka emakhisheni, i-LDPE yinto esifanayo ngezintsha ezininzi zikhethekileyo. Kodwa kukhala ngemoto, uqoqa okanye ungenzi lokulandelana ngokubanzi nokuthi akuyisisekelo sesikhatsi esingabangako. I-HDPE kukhona ngemoto kunye nekhatsi elidingekayo kune-LDPE, futhi kusetshenziswa kumncedisi omkhulu, kodwa kunjalo kungakwazi ukusebenza nokushona ngasinye ngamabhango abaningi.
Isigaba esingaphezulu sokuxoxwa lwesiphumo so-HDPE sibonisa ukuthi kungakho isiphi somunye wakhe ukufika kwentloko enkulu. Lolu hlobo kusetshenziswa kumahluko amandla njengemibhalo yamanje yesiphethuzi namagama asetshenziswa ngokuthi bayahlobene ngesikhatsi esikhulu. I-HDPE sikhethekileyo kakhulu kwiindawo zokusebenzela izinkambu zokugcina nemibhalo yokugcina, futhi kusetshenziswa ukwenza imibhalo yokugcina zokugcina namandla zakhe kunye nokusebenza, ubungakho besebe kakhulu.
I-LDPE engekuqondisiyo kakhulu lokuphakamisana ngeplastiki elikhulu, njengokuba kungabonakali phakathi komkhankaso– i-high density polyethylene noma i-LDPE grade plastiki. Kuyahamba ngokukhulu kwiimeyile ezidinga ukubhuka nokuseta ngaphandle kokugcina. U-HDPE ungcono lwesikweletu esilungileyo ukuba udalingene ngeplastiki engcono nokunqanaweni. Yilinganisa kakhulu ukuthi yayingafumanisa izinto zokuhlola. Futhi, ukuba udalingene ngeplastiki engazibulalanga amakhemikali, u-LLDPE ungumoya wokuqala.
