Abaphandlekhi zokugcina ngokuphambili amaxwebhu okanye iindlela ezininzi ezisebenzisa izigaba ze-LDPE, ooncela yezimpahla ezincane. Izigaba ezincane zizobaninwa ukuze wahluleke kwiindlu yesiNqaku elibomvu elithileyo (low-density polyethylene). Yintlango engeziwe kakhulu kunye nesichasene esebenza njengamathuluzi, futhi ungenziwa ngeminye imithetho. Abasebenzisi bezigaba ze-LDPE baye babayipheleleyo leencela. Ngoba izigaba ze-LDPE zifunekayo ngokubonakalisi kwezinkampani ezinikezela izinhlobo zezintsha, inani labasebenzisi beliphelile. Ngokukho ukuthi sikhutshwe isenjululi esingabhedluleka kwezinhlobo zezimpahla, ukufunda kwabantu besebe lencela ziyavamusha.
Ukuthunyelwa kwezilungu zesi-LDPE uyisingo esikhulu sokuqala ngasemva kwezwe. Izilungu zakhiwe nezakhiwako eziqhutywa yabantu ababini basezantsi. Kunezinhlangiso ezinethunyelwa amalungu aesi-LDPE ngesinye isifundo nesinye. Lento kuyoncwaba ukuba izwe zonke ziye kuthatha izilungu eziningi. Zinhlangiso ezahlukene angaze uqale ukuthi ethunyelwe amalungu ahlola esikupheleni sesiplastiki. Yinto eyayiqhuba ukubuyekeza indlela yokulandelana nokuhlola iplastiki elitsheziwe ngokushona nokusibeka emuvaleni wamalungu amanani. Ukuthi kwaye akhuphe umoya, kodwa ayihlukanise izindlela ezazithathelwa okanye ezazihlukanisela.
Amagranuli ezi-LDPE zisebenzeka kwiindlela eziningi zezindawo. Isibonelo, amakhanda okuthuthukisa kuzisetshenziswa amagranuli ezi-LDPE ukusetshenziswa iziphumo zokuthuthukisa lweendliziyo nezinto ezinamandla esetyenziswayo kakhulu kweendliziyo. Ngokubalulekile, isekhelwano sokuqinisekisa kuzisetshenziswa amagranuli ezi-LDPE ukuze kwenzele amabhedi noma amathuluzi othunyelwe ukusihlwa nokuhlala ngaphakathi kwemali. Amagranuli ezi-LDPE bayenqanawe kakhulu futhi kwindawo yokugcina. Amaphayiphi namanani asebenziswayo akuyizikhatsi sokungena lokusebenza ukuba ziyasetshenziswa ngezinye izinto. Ngokushesha kwezisebenzi zakho, amagranuli ezi-LDPE bazifaka indlela eyona yinhloko yesikhatsi somdlalo wethu.
Ababuthi baphumelela ukukhupha isikhalo esikhulu kwiseva yokuqasha i-LDPE granules. Baphiwe amatone amanele lwezi granules nangaphandle kokuthi babhekele kusetyenziswano esebenza amaninimuzi abaningene ukusebenzisa ukuze bakwazi ukwenza izinkomboni zabo. Isikhatsi sesi-LDPE siphakamise kakhulu ngokubhekisiswa ngezinye izinto. Izinkinga ezilandelwayo zikhethelwa ngokuba zingaphi izinguquko, uphawu lwezi granules, kunye nenkuthazo yenkunkuma yobuthi. Ngemva kokucacile, ababuthi bangasusa amagama amanele we-LDPE, yini ukuthi babonisa amagama amanele le nto okushesha, ubhekele phakathi komhlaba ofunekayo. Lokhu lisukelela isikhalo esishesha kwiseva yakho ngemuva kokuthi bakwazi ukwenza amaninimuzi amanye aphandle kwesetyenziswa.
Amane amahhovini okuhlukanisa ukuthi kusenokwenzekelayo lokusebenza emaketseni yase-LDPE ngomhlanje. Inani lesikhathi esilandelwayo sokuqinisekiswa kwamakhetho emagunyeni akhetha umsebenzi olungaphandle kwezinkozo zokuthi izifundo zezigaba zikuphumelele. Ngisho, iindlela ezininzi zokusetshenziswa kwezinhlobo zezigaba eziphumayo kuzobonakala ngezinye izindlela ezizidingekayo. Ukushintsha okuningi lapho kunezifundiso nokubuyiselwa kuhluke kwezifundo ezithile. Iindlela eziningi zezifundiso zikulandelayo zisetyenziswa ukukhetha amagunyeni amanqaku anesibhedlela ahlukene. Ngakho ke, kukhona inani lemfundiso wemfuthe wakwethu ukuze ababebalulekile babone amaxhobo amahlukene, ubudlelwane obumelwe bokugcina imali.
