I-HDPE=I-Polyethylene Yokuminyana Okuphezulu, noma i-polyethylene enengcindezi ephansi.Ukuminyana kungaphezu kuka-0.940.
I-LDPE=i-polyethylene ene-low density, noma i-polyethylene yomfutho ophezulu, i-polyethylene eyenziwe i-polymerized ngaphansi kwengcindezi ephezulu, nokuminyana okungaphansi kuka-0.922.
I-geomembrane emnyama kakhulukazi i-HDPE (high density polyethylene) geomembrane, kanti i-geomembrane emhlophe iningi layo i-LDPE (low density polyethylene) geomembrane.Umehluko phakathi kwakho kokubili ukuminyana nokusebenza.Ukuminyana kweyangaphambili kukhudlwana, kuyilapho ukuminyana kokugcina kuncane.Eyokuqala isetshenziswa kakhulu njengezinto ze-geotechnical, kanti lena yakamuva isetshenziswa njengomkhiqizo wefilimu.
Isizathu esenza ukuthi i-geomembrane emnyama ibe mnyama ukuthi i-geomembrane yenziwe nge-black masterbatch, eyengezwa ohlelweni lokukhiqiza lwe-geomembrane ngokulingana.Ngokuvamile, inani elincane le-masterbatch lingacubungula inani elikhulu lama-geomembranes, futhi izinhlayiya ze-geomembrane masterbatch kulula ukusetshenzwa, okungeke kuthinte ikhwalithi ye-geomembrane.
I-geomembrane emhlophe yingoba izinhlayiya ze-masterbatch ezimhlophe zengezwa ku-geomembrane, futhi izinhlayiya ze-masterbatch ezimhlophe ngeke ziphazamise ikhwalithi ye-geomembrane.Ukuminyana nokusebenza kwe-geomembrane emnyama kungaphezulu kwalokho kwe-LDPE geomembrane emhlophe ngoba iningi lakhona i-HDPE geomembrane.I-LDPE geomembrane emhlophe isetshenziswa kakhulu njengemikhiqizo yepulasitiki yefilimu, futhi isetshenziswa kabanzi.
Ngenxa yokuthi ukuminyana kwe-HDPE i-geomembrane emnyama kukhulu kunaleyo ye-LDPE emhlophe geomembrane, kokubili kuzoba nokusetshenziswa okuhlukile.Ukuqhathaniswa kwekhwalithi jikelele kufanele futhi kusekelwe ekusetshenzisweni kokubili ohlotsheni olufanayo lokwakha.Ukuqhathanisa akufanele kusekelwe emandleni abo (okungenakuqhathaniswa).Zombili zizosetshenziswa ngokuhlukile ekwakhiweni okuhlukene, futhi kwesinye isikhathi zizoba esikhundleni somunye.
I-geomembrane ye-LDPE emhlophe ino-ductility engcono kune-geomembrane ye-HDPE emnyama, futhi ukuguquguquka kwayo nakho kunamandla kune-HDPE geomembrane emnyama.I-geomembrane ye-LDPE emhlophe ehlangabezana nezicaciso zokwakhiwa kwephrojekthi iphinde ibe isizukulwane esisha sezinto ezikwazi ukumelana ne-geoimpermeable, futhi ukuguquguquka kwayo nakho kuzoba namandla kune-HDPE geomembrane emnyama kuphrojekthi efanayo.Manje, amaphrojekthi amaningi angakwazi futhi ukubona isithunzi somkhiqizo.
Kungabonakala kokungenhla ukuthi i-HDPE geomembrane emnyama ne-LDPE geomembrane emhlophe zinezinhlelo zokusebenza ezihlukene kumaphrojekthi ahlukene, angakwazi ukwenziwa jikelele.Lezi zinhlobo ezimbili zemikhiqizo zinamandla azo kanye nobuthakathaka bazo.Izinga lalezi zinhlobo ezimbili zemikhiqizo kufanele licatshangelwe ngokusekelwe ezikhundleni ezahlukene.
