I-Geomembrane ye-Linear Low Density Polyethylene (LLDPE)
Incazelo emfushane:
I-geomembrane ye-polyethylene ephansi kakhulu (LLDPE) eqondile iyinto e-polymer engangenisi amanzi eyenziwe nge-resin ye-polyethylene ephansi kakhulu (LLDPE) njengezinto eziyinhloko zokusetshenziswa ngokusebenzisa ukubumba, ifilimu ephonswe kanye nezinye izinqubo. Ihlanganisa ezinye zezici ze-polyethylene ephansi kakhulu (HDPE) kanye ne-polyethylene ephansi kakhulu (LDPE), futhi inezinzuzo ezihlukile ekuguquguqukeni, ukumelana nokubhoboza kanye nokuzivumelanisa nokwakhiwa.

Izici Zokusebenza
Ukumelana Okuhle Kakhulu Kokuvuza
Njengoba inesakhiwo esiqinile sama-molecule kanye ne-coefficient ephansi yokuvuleka, i-geomembrane ye-LLDPE ingavimbela ngempumelelo ukuvuza koketshezi. Umphumela wayo wokuvikela ukuvuza ufana nowe-geomembrane ye-HDPE, okwenza ukuthi isebenze kabanzi kumaphrojekthi adinga ukulawulwa kokuvuza.
Ukuzivumelanisa nezimo okuhle
Ibonisa ukuguquguquka okumangalisayo futhi ayiboli kalula emazingeni okushisa aphansi, inezinga lokumelana nokushisa eliphakathi kuka-70°C kuya ku-80°C. Lokhu kuyivumela ukuthi ivumelane nezindawo ezingajwayelekile noma izindawo ezinokucindezeleka okuguquguqukayo, njengemiklamo yokonga amanzi ezindaweni ezinezintaba ezinezindawo eziyinkimbinkimbi.
Ukumelana Okuqinile Kokubhoboza
I-membrane inokuqina okuqinile, futhi ukumelana kwayo nokudabuka kanye nokushayisana kungcono kunokwe-HDPE smooth membranes. Ngesikhathi sokwakhiwa, ingamelana kangcono nokubhoboka kwamatshe noma izinto ezibukhali, inciphise umonakalo ongengozi futhi ithuthukise ukuthembeka kwephrojekthi.
Ukuzivumelanisa Nezimo Okuhle Kokwakha
Ingaxhunywa ngokushisela okuncibilikayo okushisayo, futhi amandla amalunga aphezulu, okuqinisekisa ubuqotho bokuvimbela ukuvuza kwamanzi. Ngesikhathi esifanayo, ukuguquguquka kwayo okuhle kwenza kube lula ukugoba nokwelula ngesikhathi sokwakha, futhi ingafanela kangcono izisekelo eziyinkimbinkimbi njengemizimba yomhlabathi engalingani kanye nemithambeka yemigodi yesisekelo, okunciphisa ubunzima bokwakha.
Ukumelana Okuhle Nokugqwala Kwamakhemikhali
Inekhono elithile lokumelana nokugqwala kwezixazululo ze-asidi, i-alkali, kanye nosawoti, futhi ifaneleka ezimweni eziningi ezivamile ezingangeni amanzi. Ingamelana nokugqwala kwezinto ezahlukahlukene zamakhemikhali ngezinga elithile futhi yandise impilo yenkonzo.
Izinkambu Zohlelo Lokusebenza
Amaphrojekthi Okulondolozwa Kwamanzi
Ifanele amaphrojekthi angangeni amanzi amachibi amancane naphakathi, iziteshi, kanye namathangi okugcina amanzi, ikakhulukazi ezindaweni ezinezindawo eziyinkimbinkimbi noma izindawo zokuhlala ezingalingani, njengokwakhiwa kwamadamu okuhlola eLoess Plateau, lapho ukuguquguquka kwayo okuhle kanye nokusebenza okungangeni amanzi kungasetshenziswa khona. Kumaphrojekthi okulondolozwa kwamanzi esikhashana noma esizini, njengamathangi okugcina amanzi anesomiso, izinzuzo zayo zokwakha okulula kanye nezindleko eziphansi zenza kube ukukhetha okuhle.
Amaphrojekthi Okuvikela Imvelo
Ingasetshenziswa njengesendlalelo sesikhashana sokufaka amanzi - esingavimbeli ukuvuza kwezindawo zokulahla udoti ezincane, esingavimbeli ukuvuza kwezindawo zokulawula amachibi, kanye nezindonga zamachibi amanzi angcolile ezimbonini (ezimweni ezingagqwali kakhulu), okusiza ekuvimbeleni ukuvuza kokungcola nokuvikela indawo ezungezile.
Ezolimo kanye nokufuywa kwezinhlanzi
Isetshenziswa kabanzi ekuvimbeleni ukuvuza kwamanzi emachibini ezinhlanzi kanye namachibi ezinkalankala, okungavimbela ngempumelelo ukuvuza kwamanzi futhi kuthuthukise ukusebenza kahle kwemithombo yamanzi. Ingasetshenziswa futhi ekuvimbeleni ukuvuza kwamanzi emathangini okugcina amanzi okunisela ezolimo, ama-biogas digesters, kanye nokususwa komswakama kanye nezimpande phansi kwezindlu zokugcina izithombo, futhi ingavumelanisa nokuguquguquka okuncane kwenhlabathi ngenxa yokuguquguquka kwayo.
Ezokuthutha kanye nobunjiniyela bomasipala
Ingasetshenziswa njengesendlalelo esingamelani nomswakama emigwaqweni, ithathe indawo yezendlalelo zendabuko zamatshe futhi inciphise izindleko zephrojekthi. Ingasetshenziswa futhi ekuhlukaniseni imisele yamapayipi angaphansi komhlaba kanye nemigudu yekhebula ukuze kuvikelwe izindawo ezingaphansi komhlaba ekugugulekeni kwamanzi.
