I-anti-sepage membrane yamachibi ezinhlanzi angakwazi ukonga izindleko zokudla, ngakho-ke isetshenziswa kakhulu emachibini ezilwane zasolwandle nasezindaweni zokuzalanisa izinhlanzi emanzini ahlanzekile.Ngokusho kocwaningo lwamaphrojekthi amaningi wobunjiniyela, kutholakala ukuthi i-geomembrane engenakunyakaziswa iyingozi kakhulu echibini lokwazisa kanye nepulazi lezinhlanzi zokuzalanisa umkhiqizo wamanzi.Ukwengeza, eminyakeni yamuva nje, amapulazi amaningi kakhulu athenge i-geomembrane ye-anti-seepage yamachibi ezinhlanzi kubakhiqizi bekhwalithi ephezulu ye-HDPE geomembrane ye-anti-seepage, okuwuhlobo olusha lwezinto ezibonakalayo ze-geosynthetic embonini ye-aquaculture anti-seepage.
Umsebenzi oyinhloko we-anti-sepage membrane yamachibi ezinhlanzi ukugwema ukuthintana okuqondile phakathi kwezinhlanzi nongqimba lomhlabathi nokuvimbela ukungcoliswa kwamanzi.I-geomembrane pool engangeneki ayikwazi ukugwema kuphela ukunqwabelana kokusetshenziswa ongqimbeni lomhlabathi, kodwa futhi ivimbele izinhlanganisela eziyingozi njenge-ammonia, i-hydrogen chloride, i-asidi, insimbi, namanye amakhemikhali angaba yingozi ukuthi angangeni echibini, anganciphisa ingozi yokugula. .Gcina futhi ukhuthaze ukukhula nokuthuthukiswa kwezinhlanzi.I-geomembrane engangeneki yechibi lezinhlanzi ibonisa indawo ebushelelezi yechibi lezinhlanzi ukuze udoti osechibini lezinhlanzi lususwe kalula, futhi i-fish pond side slope ivikelekile ekugqwaleni.
I-geomembrane ye-anti-seepage yamachibi ezinhlanzi iyisivimbelo semvelo esingangeni manzi esishintshashintshayo, esenziwe nge-polyethylene resin (ephakathi) ephezulu, ngaphandle kwazo zonke izithasiselo.Umkhiqizo ngokwawo unenkomba ephezulu yokungangenisi (1×10-17) Cm/s).Ifilimu engangenisi kanye nezinga lokushisa elisebenzayo lefilimu yizinga lokushisa eliphakeme elingu-110℃, izinga lokushisa eliphansi kakhulu -70℃, futhi lingamelana ne-alkali eqinile, i-alkali, namafutha.Ukuguguleka komhlabathi.Inamandla amakhulu okucindezela futhi ingacabangela izidingo zamaphrojekthi wokwakha ajwayelekile.Inokumelana nokuguga okuqinile, ukuchayeka isikhathi eside futhi igcina ukusebenza kwayo kwasekuqaleni, futhi ingasetshenziswa ngaphansi kwezimo ezehlukene ezidlulele ze-geological kanye nesimo sezulu.
Ngokwesethulo esinemininingwane esenziwe unjiniyela wezobuchwepheshe woMnyango Wezokumaketha we-Geomembrane, imininingwane namamodeli abakhiqizi be-aquaculture ye-aquaculture ye-aquaculture i-Lingxiang i-Lingxiang ngokuvamile bangamamitha ayi-6 ububanzi futhi kunezinhlobo eziningi.Kodwa umehluko oyinhloko uncike ekugqineni, okungase kuhlukaniswe cishe ku-0.3mm, 0.3mm, 0.4mm, 1.5mm, 2.0Mm, 3.0Mm, njll. Kunezinhlobonhlobo zokucaciswa kanye namamodeli, angakhiqizwa ngokuzimela futhi kusetshenzwe ngokwezidingo zekhasimende.Ngaphansi kwezimo ezijwayelekile, i-geomembrane engu-0.5 mm ingasetshenziselwa amachibi ezinhlanzi.Ngokwemvelo, uma i-geomembrane ijiyile, iba ngcono ikhwalithi nempilo yesevisi ende.Ukwengeza, uma i-geomembrane ephikisana nokubona isetshenziswa echibini le-lotus, i-geomembrane ephikisana nokubona ngenhla kuka-1.0 Mm kufanele isetshenziselwe ukuba nomthelela wokunqanda ukuvuleka.
