Ukuvikelwa kwemvelo kuyisihloko esingapheli emhlabeni wonke.Njengoba umphakathi wesintu uthuthuka, indawo ezungezile yomhlaba wonke iye yonakaliswa ngokwandayo.Ukuze kugcinwe indawo ezungezile yoMhlaba ibalulekile ukuze umuntu aphile, ukuvikelwa kanye nokuphathwa kwemvelo kuzogxiliswa ekuthuthukisweni kwempucuko yabantu.Mayelana nokwakhiwa kwemboni yokuvikela imvelo, ama-geomembranes adlale indima engenakuthathelwa indawo emkhakheni wokuvikela imvelo eminyakeni yamuva nje.Ikakhulukazi, i-HDPE Geomembrane ibonise ukuvelela okuphawulekayo ekuvimbeleni amanzi kanye namaphrojekthi aphikisayo.
1. Iyini i-HDPE Geomembrane?
I-HDPE Geomembrane, egama layo eliphelele lithi “High-Density Polyethylene Geomembrane,” iwumsebenzi ongangeni manzi futhi ovimbelayo okhiqizwe kusetshenziswa (ophakathi) ne-polyethylene resin ephezulu.Izinto ezibonakalayo zinokumelana okuhle kakhulu nokuqhekeka kokucindezeleka kwemvelo, ukumelana nezinga lokushisa eliphansi, ukumelana nokuguga, nokumelana nokugqwala, kanye nohlobo olubanzi lokushisa olusetshenziswayo (-60– + 60) nempilo ende yenkonzo yeminyaka engama-50.Isetshenziswa kakhulu kumaphrojekthi amelene nokubonwa kwamakhasi afana nokuvinjwa kwezindawo zokulahla imfucumfucu yempilo, ukuvinjwa kwezindawo zokulahla imfucumfucu eqinile, ukuvimbela ukugeleza kwesikhungo sokuhlanza indle, ukuvimbela ukugeleza kwechibi lokwenziwa, kanye nokwelashwa kwemisila.
2. Izinzuzo ze-HDPE Geomembrane
(1) I-HDPE Geomembrane iwumsebenzi ongenamanzi oguquguqukayo one-coefficient ephezulu yokuphuma kwamanzi.
(2) I-HDPE Geomembrane inokushisa okuhle nokumelana nokubanda, enendawo yokushisa yokusetshenziswa yokushisa okuphezulu okungu-110 ℃, izinga lokushisa eliphansi -70 ℃;
(3) I-HDPE Geomembrane inokusimama okuhle kwamakhemikhali, ingamelana nama-asidi aqinile, ama-alkali, nokugqwala kukawoyela, okuyenza ibe into enhle kakhulu evimbela ukubola.
(4) I-HDPE Geomembrane inamandla amakhulu okudonsa, okuyinikeza amandla okudonsa ukuze ihlangabezane nezidingo zamaphrojekthi wobunjiniyela asezingeni eliphezulu.
(5) I-HDPE Geomembrane inokumelana nesimo sezulu esiqinile, nokusebenza okuqinile kokuguga, okuyivumela ukuthi igcine ukusebenza kwayo ngisho nokuchayeka isikhathi eside.
(6) I-HDPE Geomembrane eqinile ithuthukisa ukusebenza kokungqubuzana kolwelwesi olungaphezulu.Uma kuqhathaniswa nolwelwesi olubushelelezi olufanayo, lunamandla aqinile okuqina.Ubuso obumaholoholo bolwelwesi bunezinhlayiya ezimaholoholo ebusweni balo, obuzokwenza ungqimba oluncane lwegebe phakathi kolwelwesi kanye nesisekelo lapho ulwelwesi lubekwe, okuthuthukisa kakhulu amandla okuthwala we-geomembrane.
II.Amaqhinga Nezicelo ze-HDPE Geomembrane Endimeni Yokulahla Impahla
Njengamanje izindawo zokulahla imfucumfucu ziyindlela evame ukusetshenziswa kakhulu yokwelapha udoti oqinile kanye nodoti wasendlini, obonakala ngezindleko eziphansi, umthamo omkhulu wokucubungula, kanye nokusebenza okulula.Isetshenziswe kabanzi emazweni nasezifundeni eziningi futhi ibe yindlela yokuqala yokwelapha udoti wasendlini emazweni amaningi athuthukile.
High-density polyethylene geomembrane iyona esetshenziswa kakhulu anti-seepage material ekulahlisweni.I-HDPE Geomembrane igqama phakathi kwemikhiqizo yochungechunge lwe-polyethylene enamandla ayo aphezulu, izakhiwo zamakhemikhali ezizinzile, nokusebenza okuhle kakhulu kokulwa nokuguga, futhi yaziswa kakhulu abaklami nabanikazi bezimboni zokulahla imfucumfucu.
Ukulahlwa kukadoti kuvame ukubandakanya inkinga ye-leachate equkethe izinto ezinobuthi kakhulu neziyingozi, amakhemikhali ayingozi, nezinye izinkinga.Izinto ezisetshenziswa kubunjiniyela zinezimo zokusetshenziswa eziyinkimbinkimbi kakhulu, okuhlanganisa izici zamandla, izimo zemvelo, imidiya, isikhathi, njll., kanye nezici ezihlukahlukene ezibekwe phezulu.Ikhwalithi yemiphumela ephikisana nokuvuleka inquma ngokuqondile ikhwalithi yobunjiniyela, futhi impilo yesevisi ye-geomembrane futhi iyisici esiyinhloko esinquma impilo yobunjiniyela.Ngakho-ke, izinto ezivimbela ukubola ezisetshenziselwa amalayini okulahla imfucumfucu kufanele zibe nokusebenza okuhle kwe-anti-seepage, ukubola okuhle kwe-biodegradability, nokusebenza okuhle kwe-antioxidation, phakathi kwezinye izici.
Ngemva kweminyaka eminingi yocwaningo nokwenza esikhungweni socwaningo senkampani yethu i-geomembrane, i-geomembrane esetshenziswa ohlelweni lokunqanda ukuvuleka kwezindawo zokulahla imfucumfucu akumele kuphela ihambisane nezindinganiso zobuchwepheshe zamanje kazwelonke nezamazwe ngamazwe kodwa futhi ihlangabezane nalezi zidingo ezilandelayo:
(1) Ugqinsi lwe-HDPE Geomembrane akufanele lube ngaphansi kuka-1.5mm.Ugqinsi lunquma ngokuqondile isimo sokucindezeleka, ukuqina, ukumelana nokubhoboza, kanye nokuzinza kwesistimu yolayini wokulahla imfucumfucu.
(2) I-HDPE Geomembrane kufanele ibe namandla okuqina aqinile, angaqinisekisa ukuthi ngeke iphuke, idabuke, noma ikhubazeke ngesikhathi ifakwa noma isetshenziswa, futhi ikwazi ukumelana namandla enhlabathi kanye nemfucumfucu ngokwayo.
(3) I-HDPE Geomembrane kufanele ibe nokuhle kakhulu ukumelana nokubhoboza, okungaqinisekisa ukuthi ubuqotho bolwelwesi luyagcinwa ngokuhamba kwesikhathi, nokuthi ngeke kube “izimbobo” noma “izinyembezi” kulwelwesi olungaholela ekuvuzeni.
(4) I-HDPE Geomembrane kufanele ibe nokungazweli kahle kwamakhemikhali, okungaqinisekisa ukuthi ayonakaliswa noma agqwaliswe ukwakheka kwamakhemikhali emfucumfucu.Kufanele futhi imelane kahle nokuwohloka kwebhayoloji, okungaqinisekisa ukuthi ngeke ihlaselwe noma incishwe amagciwane, isikhunta, noma amanye amagciwane angatholakala endaweni yokulahla imfucumfucu.
(5) I-HDPE Geomembrane kufanele ikwazi ukugcina ukusebenza kwayo okuhle kakhulu kokunqanda ukugeleza kwamanzi isikhathi eside (okungukuthi, okungenani iminyaka engama-50), okungaqinisekisa impilo yesevisi yesikhathi eside yesistimu yelayini yokulahla imfucumfucu.
Ngaphezu kwalezi zidingo ezingenhla, i-HDPE Geomembrane esetshenziswa ezindaweni zokulahla imfucumfucu kufanele futhi iklanywe futhi ifakwe ngokuvumelana nezimo ezithile zendawo yokulahla, njengobukhulu bayo, indawo, isimo sezulu, i-geology, i-hydrology, njll. Isibonelo, uma indawo yokulahla imfucumfucu. itholakala endaweni enamatafula aphakeme amanzi, kungase kudingeke ukuthi iklanywe ngohlelo lwezintambo ezimbili noma uhlelo lokuqoqa ama-leachate olungavimbela ukungcoliswa kwamanzi angaphansi komhlaba.
Sekukonke, ukusetshenziswa kwe-HDPE Geomembrane kubunjiniyela bokulahla imfucumfucu kuyindlela ephumelelayo yokuqinisekisa ukuphepha nokuvikelwa kwemvelo kwezindawo zokulahla imfucumfucu zesimanje.Ngokukhetha izinto ezisetshenziswayo ezifanele, ukuklama amasistimu afanele, nokulandela izinqubo ezifanele zokufakwa nokunakekelwa, izindawo zokulahla imfucumfucu zingavikeleka, zisebenze kahle, futhi zizinze.
