HDPE=IPolyethylene yoXinano oluPhezulu, okanye ipolyethylene yoxinzelelo oluphantsi.Ubuninzi bungaphezulu kwe-0.940.
I-LDPE = i-polyethylene ephantsi yoxinano, okanye i-polyethylene yoxinzelelo oluphezulu, i-polyethylene i-polymerized phantsi koxinzelelo oluphezulu, kunye nobuninzi obungaphantsi kwe-0.922.
I-geomembrane emnyama ubukhulu becala yi-HDPE (i-high density polyethylene) i-geomembrane, ngelixa i-geomembrane emhlophe ubukhulu becala iyi-LDPE (i-low density polyethylene) i-geomembrane.Umahluko phakathi kwezi zimbini ubukhulu becala kukuxinana kunye nokusebenza.Ubuninzi bezinto zangaphambili zikhulu, ngelixa ubuninzi bokugqibela buncinci.Eyangaphambili isetyenziswa kakhulu njengesixhobo se-geotechnical, ngelixa le yokugqibela isetyenziswa njengemveliso yefilimu.
Isizathu sokuba i-geomembrane emnyama imnyama kukuba i-geomembrane yenziwe nge-masterbatch emnyama, eyongezwa kwinkqubo yokuvelisa i-geomembrane ngokomlinganiselo.Ngokuqhelekileyo, inani elincinci le-masterbatch liyakwazi ukucubungula inani elikhulu le-geomembranes, kwaye i-particle masterbatch ye-geomembrane kulula ukuyiqhuba, engayi kuchaphazela umgangatho we-geomembrane.
I-geomembrane emhlophe kungenxa yokuba iinqununu ezimhlophe ze-masterbatch zongezwa kwi-geomembrane, kwaye iinqununu ezimhlophe ze-masterbatch aziyi kuchaphazela umgangatho we-geomembrane.Ubuninzi kunye nokusebenza kwe-geomembrane emnyama kuphezulu kunoko kwe-LDPE geomembrane emhlophe kuba uninzi lwayo yi-HDPE geomembrane.I-LDPE geomembrane emhlophe isetyenziswa kakhulu njengemveliso yeplastiki yefilimu, kwaye ikwasetyenziswa kakhulu.
Ngenxa yokuba ubuninzi be-HDPE igeomembrane emnyama inkulu kunobo be-LDPE emhlophe geomembrane, ezi zimbini ziya kuba nokusetyenziswa okwahlukileyo.Ukuthelekisa umgangatho jikelele kufuneka kwakhona kusekelwe kwisicelo sesibini kuhlobo olufanayo lokwakha.Ukuthelekisa akufuneki kusekelwe kumandla abo (ukungenakulinganiswa).Ezi zimbini ziya kusetyenziswa ngokwahlukileyo kulwakhiwo olwahlukileyo, kwaye ngamanye amaxesha ziya kuba endaweni enye kwenye.
I-LDPE geomembrane emhlophe ine-ductility engcono kune-geomembrane ye-HDPE emnyama, kwaye ukuguquguquka kwayo kunamandla kune-geomembrane ye-HDPE emnyama.I-LDPE geomembrane emhlophe edibana neenkcukacha zokwakhiwa kweprojekthi ikwasisizukulwana esitsha semathiriyeli ye-geoimpermeable, kwaye ukuguquguquka kwayo kuya kuba namandla ngakumbi kune-HDPE geomembrane emnyama kwiprojekthi efanayo.Ngoku, iiprojekthi ezininzi zinokubona isithunzi semveliso.
Inokubonwa ukusuka ngasentla ukuba i-HDPE i-geomembrane emnyama kunye ne-LDPE geomembrane emhlophe inezicelo ezahlukeneyo kwiiprojekthi ezahlukeneyo, ezingenakwenziwa ngokubanzi.Iintlobo ezimbini zeemveliso zinamandla kunye nobuthathaka bazo.Umgangatho wezi ntlobo zimbini zeemveliso kufuneka ziqwalaselwe ngokusekelwe kwizikhundla ezahlukeneyo.
