UDHDPE olunene, okanye ipolietile enkulu elithile, yinkampani yomthwalo omncane elithile elithiwa ngokuthi iPetroleum. Kodwa, le nkampani kunjalo kuhluke kunye nokugcina kakhulu ngakho kube ungenziwe kudala kwiimbali ezininzi. UdHDPE olunene lunquma, lumphumelele lwemvula kunye nezincwadi eziningi zokugcina. Ngokuhlukene lokuncinane, kunjalo kufanele lokuhlola kumngeni wesimanje ngoba kunqwenekelwa kunye nokubhaliswa ngokushintsha kwezindlela ezininzi.
Kodwa, kunezinyathelo ezifaneleyo zombini lweHDPE ngokwesobizo, okuyingxenye lokuhlala. Ukuphakamisana kwenzekelelo yakhe yinto engekho ngenxa yokugcina olukhulu (UV radiation) ngokupheleleyo. Ngokubanzi, Blind iprodela amaxesha emfutshane emahlulekileyo emvela ukuba akasetyenziswa imibophezo yesintu; ngokushesha lokhu lokuba iHDPE lihlale phandle kumgama obungaphansi nobungaphezulu, izinto ezinikezeliwe ngalo HDPE azizange zihlabe ngokulandelana nezinja ezimbili ezikhona le ndawo.
I-resin yaziqhunyelwa ngokwesikhatsi kwisekhono esifumanekayo, lokhu kufuneka lihambiswe ngumakhiyi wokuhlala okulandelayo olusebenzisa ukuvavanya kwi-tubes noma i-sheets. I-sheets kunye ne-tubes ziqhutywa noma zihlawulwa ngemibuzo ongqondileyo. Zingaphambi kokuthi iziphumo zezinto ezizama ukuhlala kwiHDPE ezifanekiso eziphumela kule ndlela, isiphumo sokuqalaba sokusha kuhluke kakhulu. Ukuba amanani angaphezu komphilo wamathathu, lento lenzi khona kuhluke kakhulu. Izinhlanga ezidingekayo ezishintshwa kuhluke kakhulu ezilandelayo zikhethekile kusukela kwindawo yokugcina.
Ngokwesikhatsi, ukubhekisisa ngemperethi kunye nezinye izinto ezindala ezindaweni zokugcina noma zokuhlala zikhethekile ukuphatha kwalendawo yokugcina. Lokhu kungaba ngokwesikhatsi ukuba amaqhathanisi abaningi kakhulu kulesi sihlalo, ngoba bafuna ukwenza into engcono kunokuba bafundeki. Bazo bangezelele amanye amagama omncane emfanelekayo kwi-resin ukuthi ziyahamba ukuthola amandla ekupheleni kwesithathu, ngokuyinto, ukuba zibe ngaphandle kwezimpahla zesithathu.
UKuqhuba kweHDPE uqinisekisa ngokwesikhathu esincane lokusebenza kweplastika eziningi lapho, elandelayo, eyenza ukuba uyiphakamisanga ngaphandle kokubani okanye. Umoya ombili wokugcina weHDPE ubonisa ukuthi ungenakwazi ukukhulula indlela yokuhlala kumoya okanye umlayezo kunye nezinye iziplastika ezininzi, okungafanelekayo ukuthi ungavume kakhulu lokusebenza kunesiNkcukacha. Kodwa, unezinyathelo zazingaphezu kwazo. Ayisinga ngokushesha ukuprinta ngezinye iziplastika, ngokusho. Lokhu kunomphako omunye wabantu abasebenzela ukufunda amandla adabuka nokuthi azikho amandla ahlawuliweyo.
Umnikazi weHDPE usebenziso esiqinisweni, ungavamile ngemibuzo amane kwiindawo eziningi ezinsebenzisa zombini ngeemvelo engaphezulu. Kwesigaba sokuqephu, kusetyenziswa ngokuphi le ndawo yokulandelana nokugcina imibhali neemvelo eziphumaphi. Umnikazi wakwaHDPE usetyenziswa ukuba iindlebe, izicelo zesikhwama sokudla noma emvelo ethile. Ngaphandle kokulandelana, umnikazi wakwaHDPE usetyenziswa futhi ukwakhiwa komkhopho neemibuyiselwano kwesigaba somkhaba wesintshonalendlela. Oku kungaba yinto esetshenziswa ukuba ungene ngendlela lokuhlala ngokukhathaleleyo kumoya wamanzi kunye neemikhankaso okunikezela kwiimixwebhu ezahluhleni.
UDHDPE olunene kuyingxenye lokubala okulandelwayo lweentshonalweni nesintshontsho esingazange esihambiswanga ngaphandle komkhaya wakho. Isigaba Esikhulu Sokuqinisekisa kweHDPE — Iyabhaliswa Ekuhlulekile Kuningi, ngoba yini ukuba amanqaku athathwe apho amanqaku akhethwe ukuze alindele, azibhaliswe kunye nokuziphindziswa njengamanqaku amandla, phakathi kwesinye isiqephu sesizinto esifundzwane. Lento kungayipheleleyo lokuhlola izilimo ngokuphelele ngaphandle kwezililo zethunkelo.
