Ukhuseleko lokusingqongileyo sisihloko esihlala sihleli kwihlabathi jikelele.Njengoko ibutho labantu liqhubeka likhula, imekobume yehlabathi iye yonakaliswa ngakumbi.Ukuze kugcinwe indawo engqongileyo yoMhlaba ebalulekileyo ukuze umntu aphile, ukhuseleko kunye nolawulo lwemo engqongileyo luya kumiliselwa kwinguquko yempucuko yabantu.Ngokubhekiselele kulwakhiwo lweshishini lokhuseleko lokusingqongileyo, iigeomembranes zidlale indima engenakuthathelwa indawo kwindawo yokhuselo lokusingqongileyo kwiminyaka yakutshanje.Ngokukodwa, i-HDPE Geomembrane ibonise ukugqwesa okubalulekileyo ekukhuseleni amanzi kunye neeprojekthi ezichasene ne-seepage.
1. Yintoni i-HDPE Geomembrane?
I-HDPE Geomembrane, egama layo elipheleleyo "i-High-Density Polyethylene Geomembrane," yinto engangeni manzi kunye nesithintelo esiveliswa kusetyenziswa (ophakathi) i-polyethylene resin ephezulu.Izinto eziphathekayo zinokuchasana okugqwesileyo koxinzelelo lokusingqongileyo, ukuchasana nobushushu obuphantsi, ukuchasana nokuguga, kunye nokumelana nokubola, kunye noluhlu olubanzi lobushushu bokusetyenziswa (-60- + 60) kunye nobomi benkonzo ende ye-50 iminyaka.Isetyenziswa ngokubanzi kwiiprojekthi ezichasene ne-seepage ezifana nothintelo lwenkunkuma yokulahla inkunkuma yobomi, uthintelo lokulahla inkunkuma eqinileyo, uthintelo lweplanti yokucocwa kwamanzi amdaka, uthintelo lwechibi lokuzenzela, kunye nonyango lwemisila.
2. Izinto eziluncedo ze-HDPE Geomembrane
(1) I-HDPE Geomembrane yinto eguquguqukayo engangeni manzi kunye ne-coefficient ephezulu yokubona.
(2) I-HDPE Geomembrane inobushushu obuhle kunye nokumelana nokubanda, kunye nobushushu bokusetyenziswa kwendawo yobushushu obuphezulu be-110 ℃, ubushushu obuphantsi -70 ℃;
(3) I-HDPE Geomembrane inozinzo oluhle lweekhemikhali, inokuxhathisa i-acids eqinile, i-alkalis, kunye ne-oil corrosion, eyenza ibe yinto egqwesileyo ye-anticorrosive material.
(4) I-HDPE Geomembrane inamandla aphezulu, inika amandla aphezulu okukhawulelana neemfuno zeeprojekthi zobunjineli obuphezulu.
(5) I-HDPE Geomembrane inobuxhakaxhaka bemozulu obunamandla, kunye nokusebenza okunamandla okuchasana nokuguga, okuvumela ukuba igcine ukusebenza kwayo kunye nokuvezwa kwexesha elide.
(6) I-HDPE Geomembrane enqabileyo iphakamisa ukusebenza kwe-friction ye-membrane surface.Xa ithelekiswa nenkcazelo efanayo inwebu egudileyo, inamandla okuqina okuqina.Umphezulu onqabileyo we-membrane unamasuntswana arhabaxa kumphezulu wawo, oya kwenza i-gap encinci phakathi kwe-membrane kunye nesiseko xa i-membrane ibekwe, iphucula kakhulu amandla okuthwala i-geomembrane.
II.Ubuchwephesha kunye nokuSetyenziswa kwe-HDPE Geomembrane kwiNdawo yokuLahlwa kwenkunkuma
Iindawo zokulahla inkunkuma ngoku zezona ndlela zixhaphakileyo zokunyanga inkunkuma eqinileyo kunye nenkunkuma yasekhaya, ephawulwa ngeendleko eziphantsi, umthamo omkhulu wokulungisa, kunye nokusebenza okulula.Isetyenziswe ngokubanzi kumazwe amaninzi nakwimimandla kwaye ibe yindlela yokuqala yonyango yenkunkuma yasekhaya kumazwe amaninzi aphuhlileyo.
I-Polyethylene geomembrane yoxinaniso oluphezulu yeyona nto isetyenziswa kakhulu kwi-anti-seepage imathiriyeli kwiindawo zokulahla inkunkuma.I-HDPE Geomembrane igqame phakathi kweemveliso zothotho lwe-polyethylene ngamandla ayo aphezulu aphezulu, iipropathi zekhemikhali ezizinzile, kunye nokusebenza okugqwesileyo kokuchasana nokuguga, kwaye ixabiswa kakhulu ngabaqulunqi kunye nabanini bemizi-mveliso yokulahla inkunkuma.
Iindawo zokulahla inkunkuma zihlala zibandakanya ingxaki yenkunkuma equlethe izinto eziyityhefu neziyingozi kakhulu, imichiza eyingozi, kunye nezinye iingxaki.Izinto ezisetyenziswa kubunjineli zineemeko zokusetyenziswa ezintsonkothileyo kakhulu, kubandakanya izinto zamandla, iimeko zendalo, imidiya, ixesha, njl. njl., kunye nezinto ezahlukeneyo ezibekwe ngaphezulu.Umgangatho weziphumo ezichasene ne-seepage zichaza ngokuthe ngqo umgangatho wobunjineli, kunye nobomi benkonzo ye-geomembrane nayo yinto ephambili emisela ubomi bobunjineli.Ngoko ke, izinto ezichasene ne-seepage ezisetyenziselwa i-landfill liners kufuneka zibe nokusebenza kakuhle kwe-anti-seepage, i-biodegradability efanelekileyo, kunye nokusebenza kakuhle kwe-antioxidation, phakathi kwezinye izinto.
Emva kweminyaka yophando kunye nokuziqhelanisa neziko lophando lwe-geomembrane yenkampani yethu, i-geomembrane esetyenziswa kwinkqubo yokuchasana ne-seepage yeendawo zokulahla inkunkuma kufuneka ingahambelani kuphela nemigangatho yangoku yelizwe kunye neyehlabathi jikelele kodwa ihlangabezane nezi mfuno zilandelayo:
(1) Ubukhulu be-HDPE Geomembrane akufanele bube ngaphantsi kwe-1.5mm.Ubunzima bumisela ngokuthe ngqo imeko yoxinzelelo, ukuqina, ukuchasana nokugqobhoza, kunye nokuzinza kwenkqubo yokulahla inkunkuma.
(2) I-HDPE Geomembrane ifanele ibe namandla okuqina okuqina, anokuqinisekisa ukuba ayisayi kwaphuka, ikrazule, okanye ikhubazeke ngexesha lofakelo okanye ukusetyenziswa, kwaye inokumelana namandla omhlaba nenkunkuma ngokwawo.
(3) I-HDPE Geomembrane kufuneka ibe nokuchasana kokubhoboza okugqwesileyo, okunokuqinisekisa ukuba ingqibelelo ye-membrane igcinwa ixesha elide, kwaye akuyi kubakho "imingxuma" okanye "iinyembezi" kwi-membrane engakhokelela ekuvuzeni.
(4) I-HDPE Geomembrane kufuneka ibe nokumelana neekhemikhali okugqwesileyo, enokuqinisekisa ukuba ayonakaliswa okanye idliwe yimichiza yenkunkuma yokulahla inkunkuma.Kufuneka kwakhona ibe nokuchasana kakuhle nokuthotywa kwebhayoloji, enokuthi iqinisekise ukuba ayiyi kuhlaselwa okanye ithotywe yibhaktheriya, i-fungi, okanye ezinye ii-microorganisms ezinokufumaneka kwindawo yokulahla inkunkuma.
(5) I-HDPE Geomembrane kufuneka ikwazi ukugcina ukusebenza kwayo okugqwesileyo kokuchasana nokuchithwa kwexesha elide (oko kukuthi, ubuncinane iminyaka engama-50), enokuqinisekisa ubomi benkonzo yexesha elide yenkqubo yokulahla inkunkuma.
Ukongeza kwezi mfuno zingasentla, i-HDPE Geomembrane esetyenziswa kwiindawo zokulahla inkunkuma kufuneka iyilwe kwaye ifakwe ngokwemiqathango ethile yendawo yokulahla inkunkuma, njengobungakanani bayo, indawo, imozulu, i-geology, i-hydrology, njl. Umzekelo, ukuba indawo yokulahla inkunkuma. ibekwe kwindawo eneetafile eziphezulu zamanzi, kunokufuneka ukuba iyilwe ngenkqubo yelinen ephindwe kabini okanye inkqubo yokuqokelela i-leachate enokuthintela ukungcoliseka kwamanzi aphantsi komhlaba.
Ngokubanzi, ukusetyenziswa kwe-HDPE Geomembrane kubunjineli bokulahla inkunkuma yindlela esebenzayo yokuqinisekisa ukhuseleko kunye nokukhuselwa kwendalo kwiindawo zokulahla zanamhlanje.Ngokukhetha imathiriyeli efanelekileyo, ukuyila iinkqubo ezifanelekileyo, kunye nokulandela iinkqubo ezifanelekileyo zofakelo kunye nokugcinwa, iindawo zokulahla inkunkuma zinokukhuseleka, zisebenze ngakumbi, kwaye zizinze ngakumbi.
