Ulwakhiwo olusisiseko
I-geomembrane egudileyo idla ngokwenziwa ngezinto zepolymer enye, ezifana ne-polyethylene (PE), i-polyvinyl chloride (PVC), njl. Umphezulu wayo uthambile kwaye uthe tyaba, awunabume obucacileyo okanye amasuntswana.
- Iimpawu
- Ukusebenza kakuhle kokungangeni kwamanzi: Ingena kakhulu emanzini kwaye inokuthintela ukungena kwamanzi ngokufanelekileyo. Inesiphumo esihle sokuthintela amanzi, ioyile, izisombululo zeekhemikhali, njl. I-coefficient yokungangeni kwamanzi inokufikelela kwi-1×10⁻¹²cm/s ukuya kwi-1×10⁻¹⁷cm/s, nto leyo enokwanelisa iimfuno zokungangeni kwamanzi kwiiprojekthi ezininzi.
- Uzinzo oluqinileyo lweekhemikhali: Iyakwazi ukumelana ne-asidi kunye ne-alkali kunye nokumelana nokugqwala. Inokuhlala izinzile kwiindawo ezahlukeneyo zeekhemikhali kwaye ayikhukuliswa lula ziikhemikhali ezisemhlabeni. Ingakwazi ukumelana nokugqwala kwe-asidi ethile, i-alkali, ityuwa kunye nezinye izisombululo.
- Ukumelana okuhle nobushushu obuphantsi: Isenokugcina ukuguquguquka okuhle kunye neempawu zoomatshini kwindawo enobushushu obuphantsi. Umzekelo, ezinye ii-geomembranes ezithambileyo ze-polyethylene ezikumgangatho ophezulu zisenokuguquguquka okuthile kwi -60℃ ukuya kwi -70℃ kwaye azilula ukuqhekeka.
- Ulwakhiwo olulula: Umphezulu uthambile kwaye i-coefficient yokungqubana incinci, ekulungeleyo ukulaliswa kwiindawo ezahlukeneyo kunye neziseko. Ingadityaniswa ngokuwelda, ukubopha kunye nezinye iindlela. Isantya sokwakha siyakhawuleza kwaye umgangatho kulula ukuwulawula.
Inkqubo yeMveliso
- Indlela yokubumba nge-extrusion blow: Izinto eziluhlaza ze-polymer ziyafudunyezwa zize zikhutshwe nge-extruder ukuze zenze i-tube blank. Emva koko, umoya ocinezelweyo uvuthelwa kwi-tube blank ukuze ikhule kwaye inamathele kwi-mold ukuze iphole kwaye ibumbeke. Ekugqibeleni, i-geomembrane egudileyo ifunyanwa ngokusika. I-geomembrane eveliswa yile ndlela inobukhulu obufanayo kunye neempawu ezilungileyo zoomatshini.
- Indlela yokwenza iikhalenda: Izinto eziluhlaza zepolymer ziyafudunyezwa zize zikhutshwe kwaye zolulwe ngeerola ezininzi zekhalenda ukuze zenze ifilimu enobukhulu nobubanzi obuthile. Emva kokupholisa, i-geomembrane egudileyo ifunyanwa. Le nkqubo inokusebenza kakuhle kwemveliso kunye nobubanzi bemveliso, kodwa ukufana kobukhulu kuphantsi kakhulu.
IiNdawo zeSicelo
- Iprojekthi yokonga amanzi: Isetyenziselwa unyango oluthintela ukuvuza kwamanzi kwiindawo zokugcina amanzi ezifana neendawo zokugcina amanzi, amadama, kunye nemijelo yamanzi. Ingathintela ngokufanelekileyo ukuvuza kwamanzi, iphucule ukugcinwa kwamanzi kunye nokusebenza kakuhle kweeprojekthi zokonga amanzi, kwaye yandise ubomi benkonzo yeprojekthi.
- Indawo yokulahla inkunkuma: Njengesigqubuthelo esingangenisi amanzi ezantsi nangasecaleni kwendawo yokulahla inkunkuma, ithintela ukuvuza kwamanzi ukuba kungangcolisi umhlaba kunye namanzi angaphantsi komhlaba kwaye ikhusela imeko-bume yendalo ejikelezileyo.
- Isakhiwo esingangeni manzi: Sisetyenziswa njengomaleko ongangeni manzi eluphahleni, phantsi komhlaba, kwigumbi lokuhlambela nakwezinye iindawo zesakhiwo ukuthintela ukungena kwamanzi emvula, amanzi angaphantsi komhlaba kunye nolunye umswakama kwisakhiwo kunye nokuphucula ukusebenza kokungena kwamanzi kwisakhiwo.
- Imbonakalo yendalo eyenziweyo: Isetyenziselwa ukuthintela ukuvuza kwamanzi emachibini okwenziwa, amachibi okwenziwa, iindawo zamanzi zegalufa, njl.njl., ukugcina uzinzo lomzimba wamanzi, ukunciphisa ukulahleka kwamanzi, kunye nokubonelela ngesiseko esihle sokudala imbonakalo yendalo.
