Ukujabula ukuthi ithilethi siyazi kusukela nge-1900? Kuyangakwaziwe ngokupheleleyo kwiindlela zethu ezikhulu namhlanje. Siyabona ithilethi khathesi! Kungaphakathi kwenye izibophezelo esizazihlala ngenxa yalokho, iindlebe ethule ekudliwa yezinkomo nokulima nokubhedelela komoya. Isimo esincane samanqaku okunene olusebenzisa kakhulu kunye nokuba kuhluke kulandelayo kukhanyiswa njengamanqaku amahle amancane amahle elithiweyo High-Density Polyethylene (HDPE). Ukuthi HDPE kungumculo wendawo engcono kungaba kakhulu ngoba kunezinto ezimbili ezinamandla. Kungavamile, kungavamile kanye nokuhlola lokulandelayo.
HDPE uyimaterelya omncane kungaba kakhulu ngoba lingasetyenziswa ngeminyaka emingi edifanekisayo. (Ifoam isebenza phakathi kwesikhashana sesilayezwe, kwindawo ezisebenziswayo kuzikhaya nezindlu, kumane kwezinto ezisetyenziswa kulesi sikhathi sezinsuku, kunye nemibhalo yokugcina.) HDPE ungenzi lomusha ngokuphakeme, kodwa kungavamile kakhulu. Kungadlulisa umoya, kungavamile kakhulu, kanye nokuhlola imfula, amacalise, kunye nomhlophe.
Ezintathu zokugcina ngenxa yokuqinisekiswa kweHDPE ngalokhu iyinhlobo elithile yokuthi iyasebenza ngasemva kwezincwadi nezincane zomshikshi. Lokunye ukuthi kulungile ukusetshenziswa kwezicatshulwa nezinkomo ezifanayo nokuthi zihlabelele amacala wethu esibhakabhaka kunye neminyamaliso. Iyahlukene ukuba ibuyiselwe futhi lokhu kuhle kwehlathi, kunye nokuthi angaphandle kwezinto ezikhangelanga. Lokunye ukuthi iHDPE iyinhlobo engcono okanye ekuvumelweni lwendawo. Ngakho ke, iHDPE iyindaba yesikhatsi esingayibhedelela. Futhi, lokhu kulula ukuthi zisetshenziswa yona izinhlobo (njengamaphephethi, amakhulu kunye nezilondolozi) ezidinga ukuya kakhulu.
Cha, ngokushesha kakhulu, iHDPE ayiqinisekiswanga njengamanani akhathini, ukuqinisekiswa kwake kubonakali bezinto ezingazange ziziphi zezigciniswayo ngokuthi ziyiphakathi lesiNgesi. Uthani uyiphakathi lokusebenza lesiNgesi kunye nomkhankaso wesimanje. Ukusetshenziswa kweHDPE usavume ukuthi isebenza ngendlela engavumelekanga emfazweni. Okungafanele, iHDPE inakwazi ukubuyiselwa nokusetshenziswa ngazo izinhlobo ezintsha. Ukubuyisela kweHDPE ungene umoya omncane phakathi komkhankaso wabantu kunye nokuthi kuhluke ukusetyenziswa kwezinye izinto. Ngakho ke, iHDPE iyinhlobo engcono yokuzihlonipha imfazwe kunye nokuthi uzame ukubusa umoya.
Abasebenzi bavuselela igashi lethane kwi-oiil ne-natural gas ukuze ziphumelele HDPE. Ngokwesikhatsi, ngokulandelayo, lethane lizuzwa kumateriali obucabanga phakathi nge-polymer resin. Loresin ilandelwe njengezinto ezincinci zaziqalisekileyo ezininzi amahhadi, okungadingekile ukubuyiselwa kwindawo yezinto eziningi ekupheleni kwe-garden furniture kunye nokugcina komphendulo.
Umkhedullo wokuthiwa kwe-HDPE kukhona ukuba kuhluke kakhulu ngesicathalo esidingayo ngaphandle kwezinye izinto, lokunye umkhondo omuhle wakho wonke amaxesha. Lokhu kusho ukuthi kuhluke isicathalo esidingayo ukuthiwa kwe-HDPE, ukuba kuhluke kakhulu ukusetha i-planet yakho.
I-HDPE iyikhetho elungileyo ukwakhiwa komhlaba ngokuqala kunye nesikhashana, ngokuthi lokhu kubekho inqanawe engezantsi kunye nokuhlola okudla. Kwesibhedlela, i-HDPE akhishini lapho kulandelwe amasendaweni, umthengiso wemfuyo, kunye nezicatshulwa zokugcina izindlu ezifanelezo zihlola udlula okusebenza okukhuphe. Kwesikhemisithi, i-HDPE usebenzisa ukwenza amathreyi yasekhukhene kunye nokuphucumisa iphakathi lezinyezi zomsebenzi wesikhemisithi ukuze abasebenzisi bakhule bafundise amalayezo angaphambili. Kwesikhangeli sesikhatsi, i-HDPE usebenzisa ukwenza amacomponekenti ephakamisayo njenge-ithanki lemfu, amabhampera kunye nezinto zokusetyenziswa phakathi kwesikhatsi.
