I-HDPE Geomembrane VS SBS Ulwelwesi Olungangeni Manzi: Izimo Ezihlukile Zokusetshenziswa

Izinhlelo zokuvimbela amanzi nokungangenisi amanzi zibalulekile ekuqineni kwesakhiwo, ubunjiniyela bokuvikela imvelo, kanye nengqalasizinda kamasipala. Emaphrojekthini okwakha anamuhla, i-HDPE geomembrane kanye ne-SBS waterproof membrane yizinto ezimbili eziyinhloko ezingangenisi amanzi, kodwa izakhiwo zazo zezinto kanye nezindawo ezifanelekile zihlukile ngokuphelele. Onjiniyela abaningi kanye nabakhi benkontileka badidanisa i-HDPE geomembrane kanye ne-SBS waterproof membrane futhi bayisebenzise ngephutha ezimweni ezingafanele, okuholela ekuvuza kwamanzi, ukwehluleka ukuguga, noma izindleko zephrojekthi eziningi kakhulu. Lesi sihloko sihlaziya izici zazo eziyinhloko futhi sihlukanise izimo zazo zokusetshenziswa kwe-membrane waterproof ukuze kusekelwe ukukhethwa kwezinto okunembile.

Izici Eziyisisekelo Zezinto Ezibalulekile

I-geomembrane ye-HDPE iyi-liner yokwenziwa ye-polyethylene enobukhulu obuphezulu enokuvinjelwa kokuphuma kwamanzi, ukumelana namakhemikhali, kanye nokumelana nokubhoboza. Inesakhiwo sama-molecule esivaliwe ngokuphelele, ukungena kwamanzi okuphansi kakhulu, kanye nokusebenza okuzinzile ezindaweni ezinzima. Itholakala ngobukhulu obusukela ku-0.2mm kuya ku-4.0mm, ingenziwa ngokwezifiso ukuze ihlangabezane nezidingo ezahlukene zomthwalo wobunjiniyela kanye nokuvinjelwa kokuqhuma. Njengoba iphila iminyaka engama-50 ezimweni ezifihliwe, yenzelwe amaphrojekthi amakhulu okuvinjelwa kokuphuma kwamanzi emvelweni kanye ne-hydraulic kunokuvimbela amanzi okwakha okujwayelekile. I-geomembrane ye-HDPE ikhiqizwa ngokuhambisana nezindinganiso ze-GB/T 17643 (China) kanye ne-GRI GM13 (zamazwe ngamazwe), okuqinisekisa ikhwalithi ehambisanayo yezicelo zobunjiniyela bezemvelo.

I-SBS membrane engangeni manzi iyinto yokuvimbela amanzi eshintshiwe ye-bitumen ehlanganiswe nerabha ye-styrene-butadiene-styrene. Inikeza ukuguquguquka okumangalisayo, ukumelana nokushisa okuphansi, kanye nokuzivumelanisa nezimo zokuqhekeka kwesakhiwo. Le nto yendabuko engangeni manzi yesakhiwo ingangena ezindaweni eziyisisekelo ezingajwayelekile futhi iguquguquke nezakhiwo zesakhiwo, okwenza isetshenziswe kabanzi kumaphrojekthi okuvimbela amanzi ezakhiwo zomphakathi nezentengiselwano.

Umehluko Wokusebenza Okuyinhloko

Ukusebenza okulwa nokuvuza kwamanzi: I-geomembrane ye-HDPE inikeza amandla aphelele okulwa nokuvuza kwamanzi ngokungena kwamanzi cishe ku-zero. Imelana nokuguguleka kwe-asidi, i-alkali, usawoti, kanye nokuguguleka kwamagciwane, ifanelekela ikhwalithi yamanzi eyinkimbinkimbi kanye nezindawo ezingcolile. Ngokuphambene nalokho, i-membrane engangeni manzi ye-SBS inikeza ukuvikela amanzi emvula namanzi angaphansi komhlaba okuthembekile kodwa ayikwazi ukumelana nokugqwala kwamakhemikhali isikhathi eside noma ukucwiliswa kokungcola okunomthamo ophezulu.

Ukuzivumelanisa nezimo kwesakhiwo: I-SBS engangeni manzi iguquguquka kakhulu futhi iyanwebeka. Ingazivumelanisa nemifantu emincane yesakhiwo kanye nokuguquguquka kwezinga lokushisa kwezakhiwo, ilungele izakhiwo zesakhiwo eziguquguqukayo. I-geomembrane ye-HDPE inamandla amakhulu okudonseka kodwa iguquguqukayo encane; idinga isisekelo esiyisicaba nesizinzile futhi ayifaneleki ezindaweni ezivame ukuguquguquka kwesakhiwo.

Ukuqina: I-geomembrane ye-HDPE engcwatshwe igcina ukusebenza okuzinzile amashumi eminyaka ngaphandle kokuguga. I-membrane engangeni manzi ye-SBS eveziwe (engenazo izendlalelo ezivikelayo) ithambekele ekungcolisweni nasekugugeni, ngempilo yesevisi evamile yeminyaka eyi-15-25. Ngobuso obufanele bokuvikela njengesembozo sikakhonkolo noma amathayela ophahleni, impilo yesevisi ingandiswa kakhulu.

Izimo Ezisebenzayo Zezinto Ezimbili

Izimo Zobungcweti ze-HDPE Geomembrane

Ukusetshenziswa kwe-geomembrane ye-HDPE kugxile ekuvikelweni kwemvelo, amasimu e-hydraulic, kanye nezimboni okulwa nokuvuza. Kuyisinqumo esikhethekile samaphrojekthi adinga ukusebenza kwesikhathi eside kokulwa nokungcoliswa kanye nokulwa nokuvuza. Izimo ezijwayelekile zifaka phakathi ukuvinjelwa kokuvuza endaweni yokulahla imfucuza, ulwelwesi lwethangi lokuhlanza indle, ukugcinwa kwamanzi echibini kanye namachibi okwenziwa, ukuvinjelwa kokuvuza echibini le-aquaculture, kanye nokuhlukaniswa kwechibi le-tailings. Lezi zimo zidinga izinto zokumelana nokungcola kwamakhemikhali futhi zifinyelele ekungavuzini nhlobo, okungahlangatshezwa yizitho zomzimba ezivamile ezingangeni manzi.

Izimo Zobungcweti ze-SBS Waterproof Membrane

Ukusetshenziswa kwe-SBS membrane engangeni manzi kugxila ekuvimbeleni ukungcola kwezakhiwo zomphakathi nezentengiselwano. Isetshenziswa kabanzi ekwakheni ukuvimbela ukungcola kophahla (okudingekayo kuma-grade e-SBS angangeni zimpande ophahleni oluluhlaza ukuvimbela ukungena kwezimpande zezitshalo kanye nokulimala kokuqina kwesikhathi eside), ukuvimbela ukungcola phansi nasodongeni oluseceleni, ukuvimbela ukungcola kwebhuloho, kanye nokuvimbela ukungcola komhubhe. I-SBS membrane engangeni manzi ihambisana nezindinganiso ze-GB 18242 (China) kanye ne-ASTM D6162 (zamazwe ngamazwe), eziqashelwa kabanzi embonini yokuvimbela ukungcola kwezakhiwo. Inzuzo yayo enkulu ukufaka izindawo eziyinkimbinkimbi zezakhiwo nokumelana nokuguqulwa kwesakhiwo, ukuxazulula ngempumelelo izinkinga ezivamile zokuvuza kwamanzi esakhiweni okubangelwa ukushintsha kwezinga lokushisa kanye nokumiswa kwesisekelo.

Izimo Ezingasebenzi Ukuze Kubhekiselwe Kuzona Ngokucacile

i-geomembrane ye-HDPEayifaneleki ukuvikela amanzi ophahleni lwesakhiwo oluveziwe kanye nezindawo zesakhiwo ezikhubazekile. Isici sayo esiqinile senza kube lula ukuqhekeka lapho isisekelo siqhekeka, futhi asikwazi ukubopha ngokuqinile nezakhiwo zekhonkrithi, okubangela kalula ukuvuza kwamanzi emiseleni.

I-SBS engangeni manzi i-membraneAyisebenzi kumaphrojekthi okulwa nokuvuza kwemvelo njengezindawo zokulahla udoti kanye namachibi okuhambisa indle. Ayikwazi ukumelana nokugqwala kwamakhemikhali futhi izoguga futhi yehluleke ngokushesha ezindaweni ezinokungcola okuphezulu, yehluleke izidingo zesikhathi eside zokungavuki.

imibuzo ejwayelekile ukubuzwa

Q1: Ingabe i-geomembrane ye-HDPE ingayithatha indawo ye-SBS membrane yokwakha uphahla olungangenisi manzi?A: Cha. I-geomembrane ye-HDPE ayinamatheli ebusweni obuqinile futhi ayiguquguquki kakhulu. Ayikwazi ukuzivumelanisa nokuguquguquka kwesakhiwo futhi ithambekele ekungeneni kwamanzi. I-membrane engangeni manzi ye-SBS iseyindlela ejwayelekile yokwakha izinhlelo zophahla.

Q2: Ingabe i-SBS membrane engangeni manzi ingasetshenziswa ekufakweni kwemfucuza okulwa nokuvuza kwamanzi?A: Akukhuthazwa. I-SBS engangeni manzi ayinawo amandla okugqwala kwamakhemikhali futhi ayikwazi ukumelana nokuguguleka kokuvuza kwezindawo zokulahla udoti. I-geomembrane yobungcweti ye-HDPE kuphela ehlangabezana nezindinganiso zemvelo zokulwa nokuvuza.

Q3: Yikuphi okunesikhathi eside sokusebenza?A: I-geomembrane ye-HDPE inokuqina okuqine kakhulu. I-liner ye-HDPE engcwatshwe ingasebenza iminyaka engama-40-50 ngokungaguquguquki. Ngokuphambene nalokho, i-membrane engangeni manzi ye-SBS ihlala iminyaka eyi-15-25 ngaphandle kwezingqimba zokuvikela, kanye neminyaka engama-20-50 ngesembozo sokuvikela esifanele, esihlukahluka ngekhwalithi yezinto zokwakha kanye nezindinganiso zokwakha.

Isiphetho

I-geomembrane ye-HDPE kanye ne-membrane engangeni manzi ye-SBS zisebenza emikhakheni ehlukene yobunjiniyela ngaphandle kokuhlangana okusebenzayo. I-geomembrane ye-HDPE iyi-liner ekhethekile yokulwa nokuvuza kwamaphrojekthi ezemvelo kanye ne-hydraulic — yikhethe ukuze ikwazi ukumelana namakhemikhali okuthembekile kanye nezidingo eziqinile zokungavuzi. I-membrane engangeni manzi ye-SBS iyindinganiso eyinhloko yokwakha ukuvimbela amanzi — yikhethe ukuze ikwazi ukuzivumelanisa nezimo zesakhiwo kanye nokusebenza okuzinzile kokuvimbela amanzi ebusweni ezakhiweni zomphakathi nezentengiselwano. Ukukhetha izinto ezifanele ngokusekelwe ezicini zephrojekthi kugwema ngempumelelo izingozi zokuvuza ezifihliwe futhi kunciphisa izindleko zokulungisa zesikhathi eside.
