All of HDPE: oko kukuthi, iimpawu kunye nezicelo

Geomembranes ezi mihla roll izinto polymeric, nto leyo zinokwahluka Ebubanzini mm-1 ukuya kwelesi-4. Yakhiwa polyethylene, ezinepolypropylene, Polyvinyl chloride kunye nezinye izinto kunye esinobukhulu ubuncinane 0.5 mm. Ngokubhekiselele ububanzi bayo, ngoko kunokuba ukuya ku-7 m, kwaye ezingundoqo iimpawu yokusebenza kukuba geomembrane manzi ngokupheleleyo. Ayanda umda ukusetyenziswa kwayo, oko kukuthi, phakathi kwezinye izinto, kuya kuxoxwa ngezantsi.

izakhiwo

Namhlanje ke eqhelekileyo kakhulu geomembrane iHDPE, yintoni na, oko kuya kuchazwa kwinqaku. geomembrane Modern ngokusekelwe polyethylene kunokuba umphezulu textured okanye egudileyo. Oku kuya kuvumela ukuba uthathe ithuba lokuzikhethela ekwenziweni uhlobo oluthile lomsebenzi. Phakathi iimpawu eziphambili kule eziphathekayo bodwa iimpawu aphezulu amanzi. izinto ezinjalo iipropati eliphezulu emzimbeni mechanical, nto leyo ebenza ngeendlela ezahlukahlukeneyo. Xa wadibana ezilulwelo, inkqubo kwe- kunokwenzeka kuphela kwinqanaba eziphilayo. By the way kokuba kuqwalaselwe ukuba izinto ukuze isetyenziselwe intsebenziswano ngqo ngamanzi. Geomembranes abanganyangekiyo imichiza, ukuba uzinzo mbini, bhetyebhetye kwaye zonakalisa bathole zonke iintlobo nempembelelo enkulu, ngaphandle kokonakalisa kuyo. Amanqaku elongates phantsi kwempembelelo umthwalo kwi 850%, kunye namandla awo uqine inokuba kulingana 26.2 MPA.

enxibe iimpawu

Ukuba unomdla geomembrane iHDPE, yintoni na, wena ngokupheleleyo kufuneka uyazi. Le nto iyamelana imisebe yelanga, umahluko iqondo lobushushu, kwaye kananjalo zinokusetyenziswa kwimimandla wenyikima. It iyamelana zokuhlatywa yaye zingasetyenziswa uluhlu olubanzi izicelo. Sebenzisa i geomembrane banokuba yonke imimandla zezulu. Ukuba ulandela imithetho yofakelo zobungcali, ubomi neyokusebenza geomembrane kunokuba ukuya kwiminyaka 90.

Ububanzi bokusebenzisa

Kwiminyaka yakutshanje, kuya kusiba ngakumbi esisetyenziswa ngokubanzi geomembrane iHDPE. Yintoni na, phambi kokuba uthenge uze uzibuze. Le nto uneempawu ezibalaseleyo emzimbeni imichiza, oku kunikeza ithuba usebenzisa ngokutsha screens ingenwe nokuqokelela inkunkuma engamanzi kwaye eqinileyo ekunokuthiwa apha kwaye izinto eziyityhefu. Geomembrane advantageously isetyenziswa nokuhlaziya ngokutsa amachibi, amadama, umgquba kunye zingangenwa enamathela ngesinyithi anticorrosive, ikhonkrithi kunye nezinye izakhiwo, kwaye banxibelelane amanzi okusela ngexesha lokusebenza. On sale uyakwazi ukufumana iintlobo ezininzi geomembrane HDPE: Solmax 840, 860 no 880. nganye kwezi zinto - iimpawu zazo Iimpawu ezithile. Umzekelo, nezinyuko ubuncinane umyinge icala lokuqala yi-1 mm, ukanti wesibini nowesithathu - 1.5 no-2 mm, ngokulandelelana. ubukhulu roll yi 6,8x238; 6,8x159; 6,8x122 mm, ngokulandelelana, kuzo zonke ezi ntlobo.

mninzi

Ukuxinana zokufunda kuzo zonke zontathu macala efanayo, kwaye aqala 0,926 g / cm². Malungana lexinene le inwebu, kusenokuba ilingana 0,939 g / cm², eli xabiso kwesinye ngakumbi. Umxholo we carbon lulubhelu kuso zingaqala-2 ukuya kwemi-3%. Ingozi-material kunye zobude inokuba ulingana 14.7; 22 okanye 29%, ngokulandelelana.

unemihlaba eyongezelekileyo

abakhi Professional neengcibi ezisebenzisa iHDPE geomembrane, - yintoni na, kufuneka ucele phambi ezivenkileni. Le nto ineendlela ezininzi, phakathi kwabo - le nsimbi, ukusebenza, ezifuna workability ophezulu, ukusebenza kunye ukhathalelo lwendalo. Yokusetyenziswa geomembrane umgangatho ukunika nokufunwa ukwakhiwa kwezakhiwo kugcino inkunkuma ingozi yokuba kwiiklasi ezahlukeneyo. geomembrane ezinjalo ezisetyenziswa landscape nobunjineli ngesanti kubunzulu baphantsi ngempumelelo. Material ngokoqoqosho, ukusetyenziswa kwayo kunciphisa iindleko ukusebenza kunye nolwakhiwo. Enoba yintoni indawo yokusetyenziswa, ukusetyenziswa geomembranes ukucutha ubuninzi bomsebenzi, ubungakanani izinto, kwaye ikuvumela ukuba bayigqibe le projekthi ngokukhawuleza kangangoko kunokwenzeka. IHDPE geomembrane lidume ukuba ngokubekwa processability eliphezulu. It sikuko ukuba ububanzi buziimitha 7 lifinyele imfuneko beentanda ukuba usebenzise izixhobo welding. Ngenxa yoko, la magcisa azinazo imfuneko ukwenza beentanda bhukwana amalungu panels.

Geomembranes eqinile kakhulu kwaye zithembekile msebenzi. kuphuhliswa Ubuchule, kwaye umgangatho ukuya umhlathi. Phakathi kwezinye izinto, izinto imvelo ngokupheleleyo. Lusetyenziswa ekuzalweni okutsha izibonelelo ukhuselo lokusingqongileyo. Ngokusekelwe iinkcukacha, kuyenzeka ukuba ukuqinisekisa izakhiwo bodwa oluthembekileyo, loo magumbi nokuhanjiswa imithombo ungcoliseko.

Iimpawu yesicelo: i nqanaba wokulungiselela

IHDPE (polyethylene) kufuneka ebekwe kwisiseko elungisiweyo, leyo ngaphambili kususwe amatye, inkunkuma, imveliso zomgquba, kwakunye nezinye izinto eziya kuba nako ukonakalisa eli laphu. Kuyenzeka ukuba umphezulu lingenako ukuhlangabezana neemfuno ngentla, kwezi meko kucetyiswa ukuba usebenzise umaleko engundoqo yokhuselo, nto leyo iquka textile needled. Kubalulekile ukuthatha amanyathelo eyayiza ngaphandle amathuba kwiindawo zoqokelelo unamanzi kumphezulu ngxabano umaleko.

izinto Ukubeka

Xa intliziyo geotextile - iHDPE. IHDPE kufuneka ibekwe ngokungqinelana nemithetho ethile, nto leyo ukuziphikisa uhlobo lo mbandela. Kufuneka uqale ukusebenza emva ukulungiselela isicwangciso ufakelo. Kulo inkcukacha ibonisa ubungakanani kunye ehlobene nendawo imizobo, ngokunjalo welds. umsebenzi wofakelo kufuneka iquke ukugcinwa izinto ezithile, phakathi kwabo - ulwalathiso nolandelelwano yofakelo, iiphaneli ukumakisha kunye namalungu nge welding, indawo kwezakhiwo zohlobo lwemveliso yemibhobho kunye uqhagamshelwano ukuba izakhiwo ezikhoyo. Le Iimakhishithi kufuneka ibekwe ukuze seams azizange bawela ngaxa linye. Izithuba Ubuncinane phakathi iingongoma yonqumlo kufuneka 0.5 m iHDPE (high density polyethylene - isiseko material). Ukuba zilala phezu yi ububanzi kuluhlu ukusuka mm-100 ukuya 150. Ukunamathela kulo mgaqo kufuneka ibe ezinqamlezayo nezalathiso longitudinal. Master kufuneka aqinisekise ubuncinane inani welds ezenziwa yinkqubo extrusion.

Kumathambeka umbandela kufuneka zipakishwe ukusuka phezulu ukuya ezantsi, ngoko kuyimfuneko ukuba kusetyenziswe isixhobo eyodwa ebizwa ngokuba icanda. kufuneka zinike ebusweni-ankile ukulungisa imisele geomembrane phezu bobalulweyo ethambekeni. Ukuba kukho imfuneko ukomeleza geomembrane kumphezulu eziphathekayo, kuyimfuneko ukulungiselela izinto eqwalasele ekhethekileyo, oko kusenokuba iipleyiti xi izikhonkwane, iziqwengana geomembrane. kwangaphambili Recent kufuneka iqhotyoshelwe komhlaba iiankile eziphathekayo. Njengoko izinto zokubopha zingasebenza kunye ifaka.

Izindululo welding

Yintoni na geomembrane audio uza kusetyenziswa - iHDPE 1,5 mm okanye nayiphi na ubukhulu, beentanda welding kufuneka wenziwe kunye nezixhobo ezizodwa, apho uvelisa umoya oshushu. Isixhobo esisesinye ngobuwena unokwenza nesinqumka eshushu, okanye indlela edityanisiweyo. Le ndlela yokugqibela likuvumela ukuba wenze i umthungo ezimbini, neya isiteshi zokuhlola. Koko ukuze ube nako ukulawula umgangatho entlanganweni weld. Ukuba kufuneka sisebenze nakwizikhewu evalelwe okanye iindawo eziluncedo, kuhle ukusebenzisa ubugcisa extrusion welding.

endaweni yesiphelo

IHDPE mninzi leyo ikhankanywe ngasentla, kusenokuba umdla kuphela iingcali kodwa iinkosi indlu onamava, ngubani uceba ukusebenzisa zokufunda emsebenzini. Phakathi kwezinye izinto, uya kuba nomdla kwezinye iimpawu ezizodwa kakhulu geomembranes. Phakathi kwabo kukubonelela kwaye inertness ukuya alkalis acids, ezo pH kuluhlu 1.5 ukuya 14. Ekusebenzeni, akuyonto ifuthe wobushushu yokwaluphala, kodwa isiqinisekiso esisezantsi for self-ufakelo izinto yiminyaka 75.
