HDPE = High-Density Polyethylene Lolu hlobo lesi plastic elithile kakhulu nokuthi ngaphandle kwezikhungu. Ungatholakala amanye amashumi ngaphambi kokuthi akhululeke. Okuningi lokhu nge- HDPE nguqukumbuzo yazo zokugcina amanye amagama okusebenza njengamathamela. Yinto eyayixhasa ukuthi ayakwazi ukubonakala ngenqanawe yokugcina kumona amaqanda amacabango. Ngokushesha, i- HDPE iningi luchasene nezinhlobo ezintsha zemthetho weSonto (noma amarayi eziyindlebe), lokuthi yayibonisa ukuba yilokho oluhle kubheka umsebenzi wokuthi uzosetshenziswa phandle komlilo. Ngokulandelani leyo nto, abantu bazisetshenziswa i- HDPE ngokusebenzisa izimpahla nemibhokisi yesitshalo, amaphayiphi, noma amabhokisi namandla emfulweni.
LDPE uyihlobo lweLow-Density Polyethylene. Ngokugcinwa, le plastic ilandelayo akuyinkantolo ne-HDPE, ngoba kuhlukeneyo, ukhishelweni kunjalo nokusibezela. Ukuthi lokunye umoya wakhe uhlukanisayo, uqondile ukuba ungabonisa ngemibono eziningi, lokuna yinto okuthi LDPE iyinhle yokusetyenziswa ukwakha amaninimbi amacala, amabhophethelo abalulekileyo nesinye izinto zokuphakamisa. LDPE uphakathi kakhulu ukukhetha nokulandelana ngenani lokhu kakhulu phakathi komphilo wesintshabalalo HDPE, lokuna yinto okuthi kukhululekile kakhulu ukusetshenziswa ngokumona kwesikhatsi esidingeni.
Manje, ngokwesiphi siyafuna ukubuka kwiindaba zokuthi HDPE & LDPE zikhulumeka ngingezansi. U-HDPE unemibuzo engakho. Ewe, phambi kokufanelela, yingxenye elandelayo kunye nekuphakamiselo. Ukuthi oku kuyona ingxenye esidingiwe ngokukhangelwa njengesi simulani nokusebenzela. Oku kanye nekhuphelo le-HDPE lokuhlala ngokushesha kwiichemikali eziningi kunye ne-UV rays, ifaka ukuthi akudinga ukubekwa ngaphandle kwezinhlangano. Ungatholakala kwiiprodakta ezilandelwayo, njengefurniture yezinhlangano, amaphayipepa wamanzi, kunye nezicatshulwa zomoya.
Manje, sibheke u-LDPE. Leli rikeza lesahlukene lungenziwa ngeendaba zakhe ezikhulumeka kunye nezinga lokhu. U-LDPE uyihlobo olungaphakathi, ufundiswa ukuba kusukele isimo sesithunzi esingabhedlise. Leli khatho lisenzelisa ngokuphakamile kakhulu ukwenza imibiko yesiphumo esingabhedlise. U-LDPE usenzelwa ngokusukela kakhulu kancane kunye nezi rikeza ezilandelayo eziningi, futhi luhlu lenjini lwesikhatsi sokugcina kakhulu kwiimbali eziphambili.
LEDP, okunye, kungavunyelwe ngemibhali eyisisekelo. I-polyethileni usebenzisa ngezinye izinto zokusebenza ukuba imibaghi yephesi njengalokhu ulithole kumagrocery stores. Ukusetyenziswa kwakhe kukusetshenziswa komphendula wamandla, iphesi elihlupheka lokulandelana nezinto zokususa. Imifuno yahamba nge-LEDPE yokugcina ukuthi ifanele. Ngakwesoku, kukhona ukwenzeka ngokubhekisisa njengomkhombithi olusetshenziswa, amaphipha amaninzi, kunye nokusetyenziswa kokuhlola amaphethelo.
Kungabangako kakhulu kungani lento oya kusetshenziswa ngeplastiki kudingeka ukuvumela yini okufanele kwezinhlobo zakho. U-HDPE ungukho izinga lokulandelana ngesikhathi esikhangimileyo futhi umthwalo omkhulu. Kungenzimoya engasetyenziswa kakhulu; kodwa xa ufuna uphetheli wehlulekile, owesetyenziswa kakhulu, u-LDPE ungafuneka. U-LDPE: Ngiyiphatha kubaghi bese kunye nokuphakamisa kuhlu lephesi.
Ukuphakamiswa kwezilimo Ngokwesikhephe saseHDPE ngesikhephe saseLDPE Ukuphakamiswa kwezilimo kweHDPE kunye nokweLDPE kuzoqinisekisa izilimo. Ziqukethekwa kwezintathu ezifanayo, okuyingabi ukuthi ukuhlawulwa kwazo kungabonisi ukusuka lokuhlukaniswa kwekheli. Lolu hlobo lokuhlukaniswa kufanele luhambiswe ngokubalulekile xa kunyutha iplastiki. Okuningi olunempumelelo, kodwa, yinto elithile ngokuthi amabini omnyama weplastiki akavunyelwe. Ukuvunyelwa kungafinyelela ukuba lespastiki zikhethwe emva kokuba ziboniswe ekhaya apho zizoshintsha isikhuni sokushintshwa okanye ezilimo lethu.
