Ilaalinta deegaanku waa mowduuc aan waligeed ka dhicin adduunka oo dhan.Sida bulshada bini'aadamku ay si joogto ah u horumarayso, deegaanka caalamku waxa uu noqday mid sii xumaanaya.Si loo ilaaliyo deegaanka dhulka ee lama huraanka u ah badbaadada aadamaha, ilaalinta iyo maamulka deegaanku waxa ay sal u noqon doontaa horumarka ilbaxnimada aadamaha.Sida dhismaha warshadaha ilaalinta deegaanka, geomembranes ayaa door aan la bedeli karin ka ciyaaray goobta ilaalinta deegaanka sannadihii la soo dhaafay.Gaar ahaan, HDPE Geomembrane waxay muujisay caan ka ah ilaalinta biyaha iyo mashaariicda ka-hortagga-muuqaalka.
1. Waa maxay HDPE Geomembrane?
HDPE Geomembrane, oo magaceedu buuxaa yahay "Cufnaanta Sare ee Polyethylene Geomembrane," waa walxo aan biyuhu lahayn iyo caqabad la soo saaray iyadoo la isticmaalayo (dhexdhexaad ah) resin polyetylen cufnaanta sare leh.Maaddadu waxay leedahay iska caabin heer sare ah oo dillaaca deegaanka, iska caabbinta heerkulka hooseeya, caabbinta gabowga, iyo iska caabinta daxalka, iyo sidoo kale heerkul ballaaran oo isticmaalka (-60- + 60) iyo nolol dheer oo adeeg ah oo 50 sano ah.Waxaa si weyn loogu isticmaalaa mashaariicda kahortaga muuqashada sida ka hortagga wasakhda qashin-qubka nolosha, ka-hortagga wasakhda adag ee wasakhda qashinka, ka-hortagga wasakhda biyaha, ka-hortagga harooyinka macmalka ah, iyo daaweynta dabada.
2. Faa'iidooyinka HDPE Geomembrane
(1) HDPE Geomembrane waa shay aan biyuhu lahayn oo dabacsan oo leh isugeyn sare.
(2) HDPE Geomembrane waxay leedahay kulayl wanaagsan iyo iska caabin qabow, oo leh heerkulka deegaanka isticmaalka heerkul sare 110 ℃, heerkul hoose -70 ℃;
(3) HDPE Geomembrane waxay leedahay xasillooni kiimikaad oo wanaagsan, waxay iska caabin kartaa asiidh adag, alkalis, iyo daxalka saliidda, taasoo ka dhigaysa walxo ka hortag ah oo heersare ah.
(4) HDPE Geomembrane waxay leedahay awood cufan oo sarreeya, taasoo siinaya awood koronto si loo daboolo baahiyaha mashaariicda injineernimada heerka sare ah.
(5) HDPE Geomembrane waxay leedahay iska caabin cimilo oo xoog leh, oo leh waxqabadka gabowga oo xooggan, taas oo u oggolaanaysa inay sii wado waxqabadkeeda xitaa soo-gaadhista dheer.
(6) HDPE Geomembrane ee qallafsan waxay kor u qaadaysaa waxqabadka xoqida ee dusha xuubka.Marka la barbardhigo xuubka siman ee isku midka ah, waxa uu leeyahay xoog cufan.Dusha sare ee xuubku waxa ay leeyihiin qaybo qallafsan oogada sare, kuwaas oo samayn doona lakab faraq yar oo u dhexeeya xuubka iyo salka marka xuubka la dhigo, taas oo si weyn kor ugu qaadi doonta awoodda xajinta geomembrane.
II.Farsamooyinka iyo Codsiyada HDPE Geomembrane ee Goobta Qashin-qubka
Goobaha qashin-qubka ayaa hadda ah habka ugu badan ee loo isticmaalo daawaynta qashinka adag iyo qashinka guriga, oo lagu garto qiimo jaban, awood wax-qabad oo ballaaran, iyo hawlgal fudud.Waddamo iyo gobollo badan ayaa si weyn looga isticmaalay waxayna ahayd habka ugu horreeya ee lagu daweeyo qashinka guryaha ee dalal badan oo horumaray.
Geomembrane polyetylen cufan-sare ayaa ah shayga ugu badan ee ka-hortagga aragga ee meelaha qashinka lagu daadiyo.HDPE Geomembrane wuxuu ka dhex muuqdaa alaabooyinka taxanaha polyetylenka leh awood sare sare leh, sifooyin kiimiko ah oo deggan, iyo waxqabadka gabowga ee aad u wanaagsan, waxaana aad u qiimeeya naqshadeeyayaasha iyo milkiilayaasha warshadaha qashinka.
Qashin-qubka inta badan waxa ku lug leh dhibaatada leach ka kooban walxo sun ah oo khatar ah, kiimikooyin khatar ah, iyo dhibaatooyin kale.Qalabka loo isticmaalo injineernimada ayaa leh xaalado isticmaal oo aad u adag, oo ay ku jiraan arrimaha xoogga, xaaladaha dabiiciga ah, warbaahinta, waqtiga, iwm, iyo sidoo kale arrimo kala duwan oo la dul-saaray.Tayada saamaynta ka-hortagga aragga ayaa si toos ah u go'aamisa tayada injineernimada, iyo nolosha adeegga geomembrane sidoo kale waa qodobka ugu muhiimsan ee go'aaminaya nolosha injineernimada.Sidaa darteed, agabka-ka-hortagga-muuqaalka ee loo isticmaalo daahyada qashin-qubka waa inay lahaadaan waxqabad-ka-hortagga-aragtida wanaagsan, biodegradaability-ga wanaagsan, iyo waxqabadka antioxidation-ka wanaagsan, iyo arrimo kale.
Ka dib sannado badan oo cilmi-baaris iyo ku-dhaqan ah machadka cilmi-baarista geomembrane ee shirkadeena, geomembrane-ka loo isticmaalo nidaamka ka-hortagga-seegga ee goobaha qashin-qubka waa inaysan u hoggaansanayn oo keliya heerarka farsamada ee qaranka iyo kuwa caalamiga ah ee hadda jira, laakiin sidoo kale waa inay buuxiyaan shuruudaha soo socda:
(1) Dhumucda HDPE Geomembrane waa inuusan ka yarayn 1.5mm.Dhumucdiisuna waxay si toos ah u go'aamisaa xaaladda walaaca, adkeysiga, caabbinta dalool, iyo xasilloonida nidaamka qashin-qubka.
(2) HDPE Geomembrane waa in uu leeyahay awood adag oo adag, kaas oo hubin kara in aanu jebin, jeexin, ama isbeddelayn inta lagu jiro rakibidda ama isticmaalka, iyo in ay u adkeysan karto xoogga ciidda iyo qashinka qashinka laftiisa.
(3) HDPE Geomembrane waa in ay lahaataa iska caabin dalool oo aad u wanaagsan, taas oo hubin karta in hufnaanta xuubka ay sii ahaato waqti ka dib, iyo in aanay jiri doonin "daloollo" ama "ilmo" xuubka oo keeni kara in ay dareeraan.
(4) HDPE Geomembrane-ku waa inuu lahaadaa iska caabin kiimiko oo heersare ah, kaas oo hubin kara in aanu dhaawacmin ama daxaloobay isku-dhafka kiimikaad ee qashinka qashinka.Waa inay sidoo kale iska caabin fiican u yeelataa xaalufka bayooloji, taas oo dammaanad qaadi karta inaan lagu weerarin ama aan la dumin bakteeriyada, fungi, ama noolaha kale ee yaryar ee laga heli karo deegaanka qashin-qubka.
(5) HDPE Geomembrane waa inay awood u yeelataa inay ilaaliso waxqabadkeeda aadka u fiican ee ka-hortagga-aragga muddo dheer (ie, ugu yaraan 50 sano), taas oo hubin karta nolosha adeegga muddada-dheer ee nidaamka qashin-qubka.
Marka lagu daro shuruudaha kor ku xusan, HDPE Geomembrane ee loo isticmaalo qashin-qubka waa in sidoo kale loo qaabeeyaa laguna rakibaa iyadoo loo eegayo shuruudaha gaarka ah ee goobta qashin-qubka, sida cabbirkeeda, goobta, cimilada, geology, hydrology, iwm. Tusaale ahaan, haddii qashin-qubka Waxay ku taal meel leh miisaska biyaha sare, waxaa laga yaabaa inay u baahato in lagu nashqadeeyo nidaam labajibbaaran ama hab ururin dheecaan ah oo ka hortagi kara wasakhowga biyaha dhulka hoostiisa.
Guud ahaan, isticmaalka HDPE Geomembrane ee injineernimada qashinka qashinka waa hab wax ku ool ah oo lagu hubiyo badbaadada iyo ilaalinta deegaanka ee qashinka casriga ah.Adiga oo dooranaya agabka saxda ah, samaynta habab sax ah, iyo raacitaanka hababka saxda ah ee rakibaadda iyo dayactirka, qashin-qubka waxay noqon karaan kuwo badbaado leh, waxtar badan, iyo kuwo sii waaraya.
