I-Geomembrane liners zizinto eziyimfuneko ezisetyenziswa kwiiprojekthi ezahlukeneyo zokwakha kunye nokusingqongileyo ukuthintela ukuphuma kwamanzi kunye neegesi. Phakathi kweentlobo ezahlukeneyo ze-geomembrane liners ezikhoyo kwiimarike, i-HDPE (i-High-Density Polyethylene), i-PVC (i-Polyvinyl Chloride), kunye ne-LLDPE (i-Linear Low-Density Polyethylene) i-geomembrane liners zisetyenziswa ngokubanzi. Uhlobo ngalunye lweijeombrane lineineempawu zayo ezizodwa kunye nokusetyenziswa, okwenza ukuba kubalulekile ukuqonda umahluko phakathi kwazo.
HDPE geomembrane linerszenziwe nge-high-density polyethylene, i-polymer ye-thermoplastic eyaziwa ngokuba namandla kunye neempawu zayo ezihlala ixesha elide. Iilayini ze-HDPE zisetyenziswa ngokuqhelekileyo kwizicelo apho ukuchasana kweekhemikhali eziphezulu kunye nokuchasana kwe-UV kuyadingeka, njengakwiindawo zokulahla inkunkuma, imisebenzi yemigodi, kunye neentambo zamachibi. Amandla aphezulu we-tensile kunye nokumelana nokugqobhoza kwenza ukuba ilungele iiprojekthi ezifuna ukuqina kwexesha elide kunye nokukhuselwa kwizinto ezisingqongileyo.
PVC geomembrane liners, ngakolunye uhlangothi, zenziwe nge-polyvinyl chloride, i-polymer yeplastiki yokwenziwa eyaziwayo ngokuguquguquka kwayo kunye nokuchasana neekhemikhali. Iilayini zePVC zidla ngokusetyenziswa kwizicelo apho ukuguquguquka kunye ne-weldability zibalulekile, njengokuqulathwa kwamanzi, amachibi okuhombisa, kunye namachibi ezolimo. I-PVC geomembrane liners ziyaziwa ngokulula kwazo ukufakela kunye nokukwazi ukuhambelana nemigangatho engaqhelekanga, ezenza ukuba zibe lukhetho oludumileyo kwiiprojekthi ezahlukeneyo zokuqulatha.
LLDPE iilayini zegeomembranezenziwe nge-linear low-density polyethylene, i-flexible ne-resilient material eyaziwa ngokuxhathisa ukugqobhoza kunye neempawu zokwandisa. Iilayini ze-LLDPE ziqhele ukusetyenziswa kwizicelo apho ukuguquguquka kunye nobude bubalulekile, njengakwizigqubuthelo ezidadayo, isiqulatho sesibini, kunye neelitha zomjelo. Ikhono lezinto eziphathekayo ukuhambelana ne-substrate kunye nokuxhathisa i-punctures yenza ukuba ilungele iiprojekthi ezifuna umgangatho ophezulu wokuguquguquka kunye nokuqina.
Xa uthelekisa i-HDPE, i-PVC, kunye ne-LLDPE i-geomembrane liners, iyantlukwano engundoqo emininzi ibonakala. Iintambo ze-HDPE ziyaziwa ngamandla abo aphezulu kunye nokuxhathisa imichiza, okwenza ukuba zilungele izicelo apho ukuqina kwexesha elide kubalulekile. Iilayini zePVC zixatyiswa ngenxa yokuguquguquka kwazo kunye nokuwelda, zizenza zilungele iiprojekthi ezifuna ukufakwa lula kunye nokuhambelana nemigangatho engaqhelekanga. Iilayini ze-LLDPE zixabiswa ngenxa yokuguquguquka kwazo kunye nokuxhathisa ukugqobhoza, okuzenza zilungele izicelo ezifuna umgangatho ophezulu wokuqina kunye nobude.
Ekugqibeleni, ukhetho phakathi kwe-HDPE, i-PVC, kunye ne-LLDPE i-geomembrane liners ixhomekeke kwiimfuno ezithile zeprojekthi. Uhlobo ngalunye lweijeombrane lineinikeza iipropati ezizodwa kunye neenzuzo, okwenza ukuba kubaluleke kakhulu ukuqwalasela izinto ezifana nokuxhathisa imichiza, ukuguquguquka, kunye nokumelana nokubhoboza xa ukhetha izinto ezifanelekileyo kakhulu kwisicelo esithile. Ngokuqonda umahluko phakathi kwe-HDPE, i-PVC, kunye ne-LLDPE i-geomembrane liners, iinjineli kunye nabaphathi beeprojekthi banokwenza izigqibo ezinolwazi ukuqinisekisa impumelelo kunye nexesha elide lokugcinwa kwabo kunye neeprojekthi zokukhusela indalo.
