I-geomembrane ebushelelezi
Incazelo emfushane:
I-geomembrane ebushelelezi ivame ukwenziwa ngezinto ze-polymer eyodwa, njenge-polyethylene (PE), i-polyvinyl chloride (PVC), njll. Ubuso bayo bubushelelezi futhi buyisicaba, abunazo izinhlayiya noma ukuthungwa okusobala.
Isakhiwo esiyisisekelo
I-geomembrane ebushelelezi ivame ukwenziwa ngezinto ze-polymer eyodwa, njenge-polyethylene (PE), i-polyvinyl chloride (PVC), njll. Ubuso bayo bubushelelezi futhi buyisicaba, abunazo izinhlayiya noma ukuthungwa okusobala.
- Izici
- Ukusebenza kahle kokungangeni kwamanzi: Inokungena kwamanzi okuphansi kakhulu futhi ingavimbela ngempumelelo ukungena koketshezi. Inomthelela omuhle wokuvinjelwa kwamanzi, uwoyela, izixazululo zamakhemikhali, njll. I-coefficient yokulwa nokuphuma kwamanzi ingafinyelela ku-1×10⁻¹²cm/s kuya ku-1×10⁻¹⁷cm/s, okungahlangabezana nezidingo zokungangeni kwamanzi zamaphrojekthi amaningi.
- Ukuqina kwamakhemikhali okuqinile: Inokumelana okuhle kakhulu kwe-asidi ne-alkali kanye nokumelana nokugqwala. Ingahlala izinzile ezindaweni ezahlukene zamakhemikhali futhi ayiguguleki kalula ngamakhemikhali asemhlabathini. Ingamelana nokugqwala kwamazinga athile e-asidi, i-alkali, usawoti kanye nezinye izixazululo.
- Ukumelana okuhle nokushisa okuphansi: Isengagcina ukuguquguquka okuhle kanye nezakhiwo zemishini endaweni enokushisa okuphansi. Isibonelo, amanye ama-geomembrane abushelelezi e-polyethylene asezingeni eliphezulu asenokuguquguquka okuthile kusuka ku--60℃ kuya ku--70℃ futhi akulula ukuwaphula.
- Ukwakhiwa okulula: Ubuso bubushelelezi futhi i-coefficient yokungqubuzana incane, okulula ukuyibeka ezindaweni ezahlukene kanye nasezisekelweni. Ingaxhunywa ngokushisela, ukubopha nezinye izindlela. Ijubane lokwakha liyashesha futhi ikhwalithi kulula ukuyilawula.
Inqubo Yokukhiqiza
- Indlela yokubumba nge-extrusion blow: Izinto zokusetshenziswa ze-polymer ziyashiswa zibe sesimweni esincibilikisiwe bese zikhishwa nge-extruder ukuze kwakheke i-tube blank. Bese, umoya ocindezelwe uvuthelwa epayipini elingenalutho ukuze ukhule futhi unamathele esikhumbeni ukuze kuphole futhi kulolongwe. Ekugcineni, i-geomembrane ebushelelezi itholakala ngokusika. I-geomembrane ekhiqizwa yile ndlela inobukhulu obufanayo kanye nezakhiwo ezinhle zemishini.
- Indlela yokufaka ikhalenda: Izinto zokusetshenziswa ze-polymer ziyashiswa bese zikhishwa futhi zelulwe ngama-roller amaningi ekhalenda ukuze kwakhiwe ifilimu enobukhulu nobubanzi obuthile. Ngemva kokupholisa, kutholakala i-geomembrane ebushelelezi. Le nqubo inokusebenza kahle kokukhiqiza okuphezulu kanye nobubanzi bomkhiqizo obanzi, kodwa ukufana kobukhulu kuphansi kakhulu.
Izinkambu Zohlelo Lokusebenza
- Iphrojekthi yokonga amanzi: Isetshenziselwa ukwelashwa kwezindawo zokugcina amanzi njengezindawo zokugcina amanzi, amadamu, kanye nemisele. Ingavimbela ngempumelelo ukuvuza kwamanzi, ithuthukise ukusebenza kahle kokugcinwa kwamanzi kanye nokuhanjiswa kwawo kwamaphrojekthi okonga amanzi, futhi yandise impilo yephrojekthi.
- Indawo yokulahla udoti: Njengoba iwumngcingo ovimbela ukuvuza kwamanzi phansi nasohlangothini lwendawo yokulahla udoti, ivimbela ukuvuza kwamanzi ekungcoliseni inhlabathi namanzi angaphansi komhlaba futhi ivikela indawo ezungezile yemvelo.
- Isakhiwo esingangeni manzi: Sisetshenziswa njengengqimba engangeni manzi ophahleni, engaphansi komhlaba, endlini yokugezela nakwezinye izingxenye zesakhiwo ukuvimbela ukungena kwamanzi emvula, amanzi angaphansi komhlaba kanye nomswakama okhunye esakhiweni nokuthuthukisa ukusebenza kokungena kwamanzi kwesakhiwo.
- Indawo yokwenziwa: Isetshenziselwa ukuvimbela ukuvuza kwamachibi okwenziwa, amachibi okwenziwa, izindawo zamanzi zegalofu, njll., ukugcina ukuqina kwamanzi, ukunciphisa ukulahleka kwamanzi, nokunikeza isisekelo esihle sokudala indawo.
Imininingwane kanye nezinkomba zobuchwepheshe
- Imininingwane: Ubukhulu be-geomembrane ebushelelezi buvame ukuba phakathi kuka-0.2mm no-3.0mm, kanti ububanzi buvame ukuba phakathi kuka-1m no-8m, okungenziwa ngezifiso ngokwezidingo zamaphrojekthi ahlukene.
- Izinkomba zobuchwepheshe: Kubandakanya amandla okudonsa, ukunwebeka ngesikhathi sokuphuka, amandla okudabuka ekhoneni langakwesokudla, ukumelana nengcindezi ye-hydrostatic, njll. Amandla okudonsa ngokuvamile aphakathi kuka-5MPa no-30MPa, ukunwebeka ngesikhathi sokuphuka kuphakathi kuka-300% no-1000%, amandla okudabuka ekhoneni langakwesokudla aphakathi kuka-50N/mm no-300N/mm, kanti ukumelana nengcindezi ye-hydrostatic kuphakathi kuka-0.5MPa no-3.0MPa.
