1. UKUNIKEZELWA KWAMANZI
Imibhobho ye-PE yenziwe ngezinto ezihlangabezana nemfuneko yetyhefu ye-WHO kwaye oku kunokuhamba ngebhasi ukuthuthwa kwamanzi okusela. Imibhobho kunye nezifakelo ezinemilinganiselo yoxinzelelo lwe-SDR 7.4 ukuya kutsho kwi-SDR 41 kwimibhobho ehambisa amanzi kunye nenkqubo yokuhambisa imibhobho kunye neentambo zenkonzo.
2. IGAS & NEOLI
Imibhobho ye-PE yokuthutha igesi kuxinzelelo oluphantsi oluphakathi luyafumaneka. Imibhobho yenzelwe ngokukodwa indawo egudileyo kwaye yenziwe lula ukuyifaka. Imigca yegesi inokufakwa kwiindawo eziphantsi. Xa kusembiwa zisetyenziswa njengezingxobo zemingxuma emifutshane njengoko zinexabiso eliphantsi. Ngenxa yeepropathi ezigqwesileyo zombhobho we-HDPE, obonisa amandla empembelelo ephezulu kunye nomhlaba omhle wokuxhathisa onobundlongondlongo. Idityaniswe nokunikezela ngokulula kunye nokufakwa, imibhobho ye-HDPE igqwesile ekuthuthweni kwezinto kunye nezinye iintlobo zegesi kubandakanya i-bio-gas.
3. UMJENGO&SIPHON
Imibhobho ye-PE isetyenziselwa ukuhambisa amanzi angaphantsi komhlaba kwizakhiwo, imigca yenkunkuma kulwelo oludlekayo kunye nanjengemathiriyeli yokufaka imibhobho yokuhambisa amanzi endlwini. Zingasetyenziselwa imisebenzi yogutyulo. Ngenxa yokunganyangeki kwayo kakuhle kweekhemikhali, i-HDPE njengesixhobo esifanelekileyo sokwenza imibhobho emikhulu yeendlela zogutyulo. Zikulungele ngokufanelekileyo ukulahlwa kwenkunkuma kwimizi-mveliso kwaye zisetyenziswa ngokomlinganiselo okhulayo njengomjelo ophantsi komhlaba ohambisa amanzi amdaka kunye nemibhobho yenkunkuma.
4. USHISHINO & NEKHEMICAL
Iimpawu ezinjengokumelana nomhlwa, ukufakwa lula, ubunzima obulula, kunye nokuguquguquka kwenza imibhobho ye-PE ilungele ukuntsonkotha kwiifektri, ilungele imichiza eyonakalisayo.
5. UMBANE & NOMnxeba
Iinkqubo zemibhobho ye-PE zivunyiwe ukuba kufakwe zonke iintlobo zomhlaba. I-Polyethylene yinto eguquguqukayo kwaye inzima yombhobho. Ngoko ke, ezi nkqubo zifaneleke ngokukodwa ukufakela kwimihlaba echaphazeleka kumhlaba kunye nombhobho oqinileyo. Ukusetyenziswa kweendlela ezahlukeneyo zokudityaniswa kuthintela inkqubo yokubonelela ngobungqina obuvuzayo. Ngenxa yobunzima bokukhanya kunye neendlela ezilula zokudibanisa, iipayipi ze-HDPE zifanelekile kakhulu kwiimeko ezingathandekiyo zokufakwa kwindawo enzima.
6. UKUNKCENKCESHELA
Umbhobho wokunkcenkceshela we-PE luhlobo lwenkqubo yombhobho yokunkcenkceshela kwezolimo. Ukusebenza kakuhle kwemibhobho ye-PE kwenza inkqubo yokunkcenkceshela isebenze ngokufanelekileyo, iqinisekisa ukunkcenkceshela okwaneleyo kuzo zonke iikona zentsimi kunye nokuphucula isivuno kunye nomgangatho wezityalo. Ngeenkqubo zokunkcenkceshela zokonga amanzi ezifana nokunkcenkceshela kunye nokunkcenkceshela okuncinci, umbhobho we-PE unciphisa ngokufanelekileyo ukuphuphuma kwamanzi kunye nokuvuza. Oku kuneempembelelo ezibalulekileyo ekunciphiseni ukunqongophala kwamanzi. Umbhobho we-PE unobomi obude benkonzo, iindleko zokugcinwa okuphantsi, kwaye unokunciphisa uhlahlo lwabiwo-mali olubanzi lweprojekthi. Oku kuya kunceda ekunciphiseni umthwalo woqoqosho lwamafama nokuphucula inzuzo yezoqoqosho kwimveliso yezolimo.
7. IMGODI
Umbhobho wonikezelo lwamanzi we-PE udlala indima ebalulekileyo kwishishini lemigodi ngenxa yokunganyangeki kwayo okubandayo, ubomi benkonzo ende, ukuxhathisa umhlwa kunye nezinye iimpawu.
● Ukuthuthwa kwamanzi: Umbhobho wokuhambisa amanzi we-PE ngenxa yokumelana nokugqwesa kakuhle kunye nokumelana nokuguga, unokumelana neendawo ezahlukeneyo zemizi-mveliso enzima, ngoko isetyenziselwa umgodi wokuhambisa amanzi, njengamanzi, izisombululo zamachiza, njl., Ukuqinisekisa inkqubela phambili egudileyo yokusebenza kwemigodi.
● Ukukhutshwa kwegesi: Umbhobho wokuhambisa amanzi we-PE nawo ufanelekile kwi-gas drainage, ukuqinisekisa ukhuseleko lwenkqubo yemigodi, ukuphepha ukuqokelelwa kwegesi okubangelwa yimingcipheko yokhuseleko.
● Ukuthuthwa kweentsalela zezimbiwa: Iintsalela zezimbiwa ezenziwe kwinkqubo yokomba kufuneka zihanjiswe kwaye zicocwe ngemibhobho. Ngenxa yokuqina kunye nokuthembeka kwayo, umbhobho wonikezelo lwamanzi we-PE lolona khetho lufanelekileyo lokuthuthwa kweetailings.
8. AMANZI
Umbhobho we-HDPE uneempawu zokuqina okuphezulu kunye nokumelana nokugqwala, okungakwazi ukulungelelanisa neemeko ezinzima zommandla waseLwandle kunye nokuqinisekisa ukuzinza kunye nokuqina kwe-cage. Indlela ye-welding eshushu yokunyibilika kombhobho we-PE yenza isakhelo sesakhelo siqine, sinokuxhathisa impembelelo yomoya kunye namaza, kwaye siqinisekise ukhuseleko lwezinto eziphilayo ezizalayo. Umbhobho we-PE udlala indima ebalulekileyo kumjikelezo womgangatho wamanzi kunye nenkqubo yokucoca, ukuxhathisa kwayo okulungileyo kunye nokumelana nokunxiba kwenza umbhobho we-PE ube yinto efanelekileyo yokukhetha. Ngoyilo lwenkqubo yenzululwazi kunye nengqiqo, umbhobho we-PE unokukhupha ngokufanelekileyo izinto ezinobungozi kumanzi aselwandle, kwaye ungenise umthombo wamanzi amatsha okanye amanzi acociweyo, ugcine umgangatho wamanzi ucocekile kwaye uzinzile, uphucule ukusetyenziswa kakuhle komzimba wamanzi, ukunciphisa iziganeko zezifo .
