I-geomembrane iyisembozo esinciphile sokwenziwa noma isivikelo esiklanyelwe ngokukhethekile ukulawula ukuhamba koketshezi nezinga ezintweni ezizungezile emhlabathini. Ngamazwi alula, lawa mashidi aguquguqukayo asebenza njengesihlangu esingangeneki esigcina uketshezi lapho kufanele khona, kungaba ukugcina amanzi echibini noma ukuvimbela ukungcola ekutheleni okuphuma endaweni yokulahla imfucuza. Umsebenzi oyinhloko wanoma iyiphi i-geomembrane ukuvimbela ukuhamba okungalawuleki kwamanzi, i-leachate, amakhemikhali, noma igesi, ngaleyo ndlela kuvikelwe imvelo kanye nokuqina kwesakhiwo samaphrojekthi obunjiniyela bomphakathi. Ngenxa yale ndima ebalulekile, ama-geomembrane manje abhekwa njengezingxenye ezibalulekile ezinhlelweni zesimanje zokuvikela imvelo kunokuba kube izengezo ozikhethela zona ekwakhiweni komklamo.

Uhla lwezinhlelo zokusebenza zalezi zinto zokuvimbela i-geosynthetic luyamangaza ngempela, luhlanganisa yonke into kusukela ezindaweni zokulahla imfucuza eqinile namachibi okuhlobisa asengadini kuya emadamu amakhulu nemithombo yezindawo zokugcina izinto ezimayini. Onjiniyela bathembela kuzo ezingubeni zezindawo zokulahla imfucuza, izinhlelo zokulawula ukuguguleka kwenhlabathi, izitsha zokulawula inzika, izindwangu zokuvimbela emiseleni, kanye nezinye izakhiwo eziningi ezidinga ukuvimbela uketshezi ngokuphelele. Kwezolimo, zakha amachibi okufuya izinhlanzi akhiqizayo namadamu okunisela, kuyilapho emkhakheni wezamandla zihlanganisa izindawo zokugcina izinsalela eziqukethe imikhiqizo eyingozi yezimayini. Ngayinye yalezi zindawo idinga izinto ezihlukene kumalayini wokuvimbela, okusho ukuthi ukuqonda izinhlobo ezahlukene zama-geomembrane atholakalayo kubalulekile kunoma ubani ohlela iphrojekthi yokuvimbela okokuqala.

Ukuze uqonde ngokugcwele ukubaluleka kwe-geomembrane, kuyasiza ukuqonda ukuthi ihambisana kanjani nomndeni obanzi wama-geosynthetics, okubandakanya nama-geotextiles, ama-geogrids, ama-geocells, ama-geonets, kanye nama-geosynthetic clay liners. Umehluko oyisisekelo kakhulu usekudluliseni kwamanzi, ngoba amanye ama-geosynthetics aklanyelwe ukuvumela amanzi ukuthi adlule kuyilapho amanye aklanyelwe ukuwavimba ngokuphelele. Imikhiqizo edlulisa amanzi efana ne-Nonwoven Geotextiles kanye nama-geogrids inikeza imisebenzi efana nokuhlunga, ukudonsa amanzi, ukuqinisa, nokuhlukanisa, ivumela amanzi ukuthi ageleze kuyilapho igcina izinhlayiya zenhlabathi. Ngokuphambene, izithiyo ezingadlulisi amanzi ezifana nama-geomembranes kanye ne-Geosynthetics Clay Liner (GCL) imikhiqizo ikhiqizwa ngokukhethekile ukuze ivimbe uketshezi namagesi ukuthi kungadluli, okubenza babaluleke kakhulu ekulawuleni ukungcola.

Ukubaluleka kwalezi zithiyo ezingangeneki akukwazi ukweqiwa uma sicabanga ngemiphumela yokuhamba koketshezi ezindaweni ezibucayi. Uma i-leachate enobuthi evela endaweni yokulahla imfucuza ingena emanzini angaphansi komhlaba, ingangcolisa imithombo yamanzi okuphuza, ilimaze izilwane zasendle, futhi idale izikweletu ezinkulu zokuhlanza kubantu abanecala. Ngokufanayo, uma ichibi lasepulazini lilahlekelwa amanzi ngokungena ngaphansi, umnikazi uhlangabezana nokuncipha komthamo wokugcina amanzi kanye nokumosha izinsiza, kuyilapho ukwehluleka kokuqukatha kwezimayini kungaholela ezinhlekeleleni zemvelo ezimbi kakhulu eziba izindaba eminyakeni eminingi. Yingakho nje imithetho yezemvelo emazweni amaningi manje igunyaza ukusetshenziswa kwezinto ezingangeneki eziqinisekisiwe ekulahleni imfucuza, ekugcineni uketshezi lwezimboni, nasekuqukatheni izinto eziyingozi.

Uma uqala ukuhlola izinketho ze-geomembrane, uzothola ngokushesha ukuthi lezi zinto zokufaka zihlukene zibe izigaba ezimbili ezibanzi: amafilimu angakhiqizwanga ngokuqinisa kanye nama-geomembrane aqinisiwe, ngayinye yakhelwe izimfuno zokusebenza ezihlukene. Amafilimu angakhiqizwanga ngokuqinisa amashidi anongqimba olulodwa akhiqizwa ngesisekelo se-polymer ngaphandle kwanoma iyiphi indwangu yangaphakathi noma ukuqiniswa kwe-scrim, okuwenza abe nezindleko eziphansi, aguquguqukayo, futhi alula kakhulu ukufakwa ezindaweni eziningi zamaphrojekthi. Lawa mafilimu ahlinzeka ngokumelana namakhemikhali okuhle kakhulu, ukuzinza okuhle kwe-UV, kanye nokumelana nokubhobozwa okuhle ngobukhulu bawo, okuwenza abe yisinqumo esithandwa kakhulu sezinhlelo zokugcina okwesibili kanye nezici zamanzi zokuhlobisa. Ngenxa yokuthi angahlanganiswa ngokuthembekile kusetshenziswa izindlela ezijwayelekile zokushisa noma zokukhipha, ama-geomembrane angakhiqizwanga ngokuqinisa ayisicaciso esizenzakalelayo samaphrojekthi lapho inani nokulula kuyizinto ezibaluleke kakhulu.

Izigameko ezijwayelekile zokusetshenziswa kwamafilimu angaqinisiwe zihlanganisa ukuvalwa kwesibili ezindaweni eziseduze namathangi okugcina uphethiloli, amadamu ezolimo, amachibi okuhlobisa, izindawo zokuzalela izinhlanzi, kanye nezakhiwo zesikhashana zokukhipha amanzi ezakhiweni, lapho izimo zokusebenza zingezinhle kakhulu. Ama-geomembrane aqinisiwe, ngakolunye uhlangothi, afaka isendlalelo sendwangu elukiwe noma engalukiwe ngaphakathi kwipholima, okuthuthukisa kakhulu amandla okudonsa kanye nokuzinza kobukhulu. Lokhu kuqiniswa kuvumela isendlalelo ukuthi simelane nengcindezi enkulu, simelane nokudabuka lapho sibhekene nezindawo ezingalingani, futhi sisebenze ngokuthembekile ezinhlelweni ezinzima njengemithambeka eqondile, inhlabathi enamatshe, kanye nezindawo eziyisisekelo zokulahla udoti ezinokuhamba okukhulu. Uma iphrojekthi yakho ihilela indawo engalingani, ukulayishwa okukhulu kwemishini, noma izimo zemvelo ezinolaka, i-geomembrane eqinisiwe izokunikeza ukuqina okwengeziwe nokuqiniseka okudingayo esikhathini eside.

Izici zokusebenza kwanoma iyiphi i-geomembrane zinqunywa kakhulu ngamapholima asetshenziswa ekukhiqizeni kwayo, kanti i-high-density polyethylene (HDPE), i-linear low-density polyethylene (LLDPE), i-polyvinyl chloride (PVC), ne-ethylene interpolymer alloy (EIA) ziphakathi kwezinto ezivame kakhulu embonini. I-HDPE inikeza ukumelana namakhemikhali okuphezulu nokuzinza kwe-UV, okuyenza ibe into ekhethwayo ezindaweni zokulahla udoti nezokumbiwa, kuyilapho i-LLDPE inikeza ukuguquguquka okukhulu kumaphrojekthi afaka izindawo ezingalingani noma ukwehla okukhulu. Ama-geomembrane e-PVC aziwa ngokunwebeka kwawo okuhle nokusebenza kahle, kuyilapho i-EIA ihlanganisa izici ezingcono kakhulu zamapholima amaningi ukuze inikeze ukuguquguquka okukhethekile nokumelana nesimo sezulu. Into ngayinye iletha ibhalansi yayo yamandla emishini, ukumelana nokubhobozwa, ukuguquguquka, nezindleko, ngakho-ke ukukhetha okufanele kuncike ngokuphelele ezidingweni zakho ezithile zokuvalela.

Izindlela zokukhiqiza ezisetshenziselwa ukuguqula ama-polymer aluhlaza abe amaroli e-geomembrane aqediwe nazo zidlala indima ebalulekile ekhwalithini yomkhiqizo, kanti i-flat-die extrusion ne-calendaring yizona zindlela ezimbili ezisetshenziswa kakhulu. Ku-extrusion, i-polymer encibilikisiwe iphoqelelwa ukuba idlule ku-flat die ukuze kukhiqizwe ishidi eliqhubekayo elibe selipholiswa futhi ligoqwe, kuyilapho i-calendaring idlulisa impahla ngochungechunge lwamarola ashisisiwe ukuze kuzuzwe ukulawula okunembile kogqinsi. Ngesikhathi sokukhiqiza, abakhiqizi baxuba ngokucophelela izithako ezingeziwe ezifana ne-carbon black, ama-antioxidants, ama-plasticizers, ne-UV stabilizers ku-polymer ukuze kuthuthukiswe ukumelana nesimo sezulu, ukuzinza kokushisa, nokuphila isikhathi eside ezimeni zangaphandle nezingcwatshwe. E-Geofantex Geosynthetics, sibeka ukugcizelela okukhulu ekutholeni izinto zokusetshenziswa eziphezulu ezivela kubaphakeli abaqinisekisiwe, ngoba siyazi ukuthi ikhwalithi ye-resin eyisisekelo inquma ngqo ukuthi i-liner yakho izokusebenzela isikhathi esingakanani.

Omunye wemibuzo evame kakhulu abathengi abaqala ukuthenga abayobuza ukuthi i-geomembrane izohlala isikhathi esingakanani ngempela, futhi impendulo eqotho ukuthi isikhathi sokuphila kwayo sincike kakhulu kukho kokubili ikhwalithi yomkhiqizo nezimo zokusebenza.
