Xa idityaniswe ngokulula kokuphatha nokufakela, imibhobho ye-HDPE ilungile kakhulu ekuthuthweni kwezinto kunye nezinye iintlobo zegesi kubandakanya i-bio-gas.
3. I-DRAINEAGE & SIPHON
Iipayipi ze-PE zisetyenziselwa ukuthuthwa kwamanzi phantsi komhlaba kwizakhiwo, imigca yenkunkuma yolwelo olurhabaxa kunye nezinto zokufaka amanzi amdaka endlwini. Zingasetyenziselwa nemisebenzi yokuhambisa amanzi amdaka. Ngenxa yokumelana kwayo neekhemikhali okuhle kakhulu, i-HDPE isetyenziswa njengesixhobo esifanelekileyo kumenzi weepayipi ezinkulu zeenkqubo zokuhambisa amanzi amdaka. Zilungele ukulahlwa kwenkunkuma yemizi-mveliso kwaye zisetyenziswa kakhulu njengeepayipi zokuhambisa amanzi amdaka phantsi komhlaba kunye neepayipi zokuhambisa amanzi amdaka.
4. IMISHINI NEEKHEMIKHALI
Iimpawu ezinje ngokumelana nokugqwala, ukufakeka lula, ubunzima obuphantsi, kunye nokuguquguquka kwenza iipayipi ze-PE zilungele iifektri ezintsonkothileyo, Zilungele iikhemikhali ezingcolisayo.
5. UMBANE NOKUTHELEKELA I-TELECOM
Iinkqubo zemibhobho ye-PE zivunyiwe ukufakwa kuzo zonke iintlobo zomhlaba. I-Polyethylene yimbhobho eguquguqukayo neqinileyo. Ke ngoko, ezi nkqubo zifanelekile ngokukodwa ukufakwa kumhlaba ochaphazeleka lula kumhlaba kunye nezinto zemibhobho eqinileyo. Ukusetyenziswa kweendlela ezahlukeneyo zokudibanisa kuvala inkqubo yokubonelela engenakuvuza. Ngenxa yobunzima obulula kunye neendlela ezilula zokudibanisa, iipayipi ze-HDPE zifanelekile kakhulu kwiimeko ezingathandekiyo zokufakela kwiindawo ezinzima.
6. EZOLIMO NOKUNKCENKCESHA
Umbhobho wokunkcenkceshela we-PE luhlobo lwenkqubo yombhobho wokunkcenkceshela kwezolimo. Ukusebenza kakuhle kwemibhobho ye-PE kwenza inkqubo yokunkcenkceshela isebenze ngokufanelekileyo, iqinisekisa ukunkcenkceshela okwaneleyo kuzo zonke iikona zentsimi kwaye iphucule isivuno kunye nomgangatho wezityalo. Ngeenkqubo zokunkcenkceshela ezonga amanzi ezifana nokunkcenkceshela ngokuthontsiza kunye nokunkcenkceshela okuncinci, umbhobho we-PE unciphisa ngokufanelekileyo ukufuma kwamanzi kunye nokuvuza. Oku kunemiphumo ebalulekileyo ekunciphiseni ukunqongophala kwamanzi. Umbhobho we-PE unobomi obude benkonzo, iindleko zokulungisa eziphantsi, kwaye unokunciphisa uhlahlo lwabiwo-mali olupheleleyo lweprojekthi. Oku kuya kunceda ukunciphisa umthwalo wezoqoqosho lwabalimi kunye nokuphucula iingenelo zoqoqosho zemveliso yezolimo.
7. UKUMBIWA KWEMIGODI
Umbhobho wamanzi we-PE udlala indima ebalulekileyo kwishishini lezemigodi ngenxa yokumelana nokubanda, ubomi benkonzo ende, ukumelana nokugqwala kunye nezinye iimpawu.
● Uthutho olumanzi: Umbhobho wokuhambisa amanzi we-PE ngenxa yokumelana nokugqwala kwawo kakuhle kunye nokumelana nokuguguleka, unokumelana neemeko ezahlukeneyo zoshishino ezinzima, ngoko ke usetyenziswa emgodini ukuhambisa ulwelo, olufana namanzi, izisombululo zeekhemikhali, njl.njl., ukuqinisekisa inkqubela phambili ethe tye kwimisebenzi yokwemba.
● Ukukhupha amanzi ngegesi: Umbhobho wokuhambisa amanzi we-PE ukwafanelekile ekukhupheni amanzi ngegesi, ukuqinisekisa ukhuseleko lwenkqubo yokwemba, ukuphepha ukuqokelelwa kwegesi okubangelwa ziingozi zokhuseleko.
● Ukuthuthwa kweentsalela zemibhobho: Iintsalela zemibhobho eziveliswe kwinkqubo yokwemba kufuneka zithuthwe kwaye zilungiswe ngemibhobho. Ngenxa yokuqina kwayo nokuthembeka kwayo, umbhobho wokuhambisa amanzi we-PE lolona khetho lufanelekileyo lokuthuthwa kweentsalela zemibhobho.
8. I-AQUALITY
Umbhobho we-HDPE uneempawu zokuqina okuphezulu kunye nokumelana nokugqwala, onokuziqhelanisa neemeko ezinzima zokusingqongileyo kolwandle kwaye uqinisekise uzinzo kunye nokuqina kwekheyiji. Indlela yokuwelda eshushu yombhobho we-PE yenza isakhiwo sesakhelo siqine, sinokumelana nempembelelo yomoya kunye namaza, kwaye siqinisekise ukhuseleko lwezinto eziphilayo ezizalisayo. Umbhobho we-PE udlala indima ebalulekileyo kwinkqubo yokujikeleza nokucoca umgangatho wamanzi, ukumelana kwayo nokugqwala okuhle kunye nokumelana nokuguguleka kwenza umbhobho we-PE ube lukhetho olufanelekileyo. Ngokuyila inkqubo yokujikeleza ngokwesayensi nangokufanelekileyo, umbhobho we-PE unokukhupha izinto ezinobungozi emanzini okulima, kwaye ungenise umthombo wamanzi acocekileyo okanye amanzi acociweyo, ugcine umgangatho wamanzi ucocekile kwaye uzinzile, uphucule ukusebenza kakuhle kwamanzi, unciphise ukwanda kwezifo.
