Ukubonisa umlingani
I-HDPE geomembranes ikhiqizwa kusetshenziswa i-virgin polyethylene resin, equkethe ikakhulukazi u-97.5% high-density polyethylene kanye no-2.5% auxiliary additives—kubandakanya i-carbon black, ama-agent wokuvikela ekugugeni, ama-antioxidants, ama-UV absorbers, kanye nezithuthukisi. Lezi geomembranes zikhishwa kusetshenziswa imishini yokukhiqiza ephelele ngokuzenzakalelayo nge-process ye-co-extrusion emithathu. Zonke imikhiqizo ikhiqizwa ngokuhambisana nezindinganiso zemboni futhi zikhona kumphakathi ophakeme wezincazelo; kokubili ama-membranes angaphumi kahle futhi anemibala anikezwa ngezinsimbi ezivela ku-0.25 mm kuya ku-3.0 mm kanye nobubanzi obuphakathi kuka-4 m kuya ku-12 m. Lezi zimpahla zifeza kahle izidingo zokusebenza ezihlukahlukene, kuhlanganise nokuvikelwa kwemvelo nokuhlanzeka, uk conserving amanzi, ukwakha, ubunjiniyela bezamasipala, ukwakhiwa kwezindawo, ama-petrochemicals, ukuhweba, ukukhiqizwa kwe-salt, ezolimo, kanye nezolimo zamanzi.
Izicelo zama-Geomembrane e-HDPE
1. Ukuvikelwa Kwemvelo kanye Nenhlanzeko (isib. izindawo zokulahla udoti kamasipala, iziteshi zokwelapha amanzi amdaka, izindawo zokulahla udoti onobuthi nobungozi, izindawo zokugcina izinto eziyingozi, izindawo zodoti zezimboni, izindawo zodoti zokwakha nokudilizwa, njll.)
2. Ukulondolozwa Kwamanzi (isb., ukuvinjelwa ukuvuza, ukuvala ukuvuza, nokuqinisa imisele yomlambo, ichibi, idamu, namadwala amadamu; ukugqokisa imisele; izindonga zokuvala eziqondile; ukuvikela imithambeka; njll.)
3. Ubunjiniyela bukaMasipala (isb., izinhlelo zemigwaqo engaphansi komhlaba, izakhiwo ezingaphansi komhlaba zezakhiwo, amathangi okugcina amanzi emvula ophahleni, izingadi ezipahleni—ukuze kuvinjelwe ukuvuza—nokugqokisa imibhobho yamanzi amdaka, njll.)
4. Ukulungisa ingadi (isb., amachibi enziwe ngabantu, amadama, izindawo zamanzi ezinkundleni zegalofu—ukuze kugqokiswe phansi—nokuvikela imithambeka, njll.)
5. Imboni Ye-Petrochemical (isib. izimboni zamakhemikhali, izimboni zokuhlanza uwoyela, iziteshi zegesi—ukuze kugcinwe amathangi kawoyela/ukuze kuvinjwe ukuvuza—amathangi okusabela amakhemikhali, amathangi okuhlala—ukuze kugcinwe—nezingqimba zesibili zokugcina, njll.)
6. Imboni Yezimayini (isb., amathangi okugeza amatshe, amadama okukhipha izimayini, izindawo zokulahla umlotha, amathangi okuncibilikisa, amathangi okuhlala, izindawo zokugcina, namadama ezinsalela—ukuze kugqokiswe phansi nokuvinjelwa ukuvuza—njll.)
7. Ezolimo (isb., amadamu, izitsha zamanzi okuphuza, amadama okugcina amanzi, nezinhlelo zokunisela—ukuze kuvinjelwe ukuvuza—njll.)
8. Ezokulima izilwane zasemanzini (isibonelo, amachibi ezinhlanzi, amachibi ezimfene—ukugqoka—namachibi omkhomo wolwandle—ukuvikela ukuthambekela—njll.)
Ukufakwa kwe-HDPE Geomembranes
1. Ngaphambi kokubeka i-HDPE geomembranes, izitifiketi zokwamukelwa ezifanelekayo zemisebenzi yobunjiniyela bomphakathi kufanele zitholwe.
2. Ngaphambi kokusika i-HDPE membrane, ubukhulu obufanele kufanele bube bukalwe ngokunembayo; ukusika kufanele kwenziwe ngokusekelwe kulokhu kulinganisa kwangempela kunokuthembela kuphela kubukhulu obukhonjiswe emidwebeni yokuklama. Ilokhu ngayinye kufanele inombolo ngokulandelana, futhi amarekhodi anemininingwane kufanele agcinwe kwilogi ezinikezelwe.
3. Lapho ubeka ama-geomembrane e-HDPE, umgomo kufanele kube ukunciphisa inani lezikhala. Ngenkathi uqinisekisa ikhwalithi, imizamo kufanele yenziwe ukonga izinto zokusetshenziswa ngangokunokwenzeka; le ndlela iphinde yenze lula ukuqinisekiswa kwekhwalithi.
4. Ububanzi bokugqagqana phakathi kwamashidi e-membrane aseduze ezindaweni zokuhlanganisa kufanele ngokuvamile bungabi ngaphansi kuka-10 cm. Ngokuvamile, ukuma kwezindawo zokuhlanganisa kufanele kuhambisane nomthambeka—okungukuthi, kuhamba ngendlela yomthambeka.
5. Ezindaweni ezinemikhawulo noma izindawo ezingalingani, ubude bezikhala buzoqiniswa ngangokunokwenzeka. Ngaphandle kokuba kufunwe ngokukhethekile, ukuhlanganisa izikhala kufanele kugwenywe—ngokwenzeka okukhulu—ezintabeni ezingaphezu kuka-1:6 ngaphakathi kwamamitha angu-1.5 ukusuka emqamutsheni wentaba noma ezindaweni lapho kuhlala khona ingcindezi.
6. Ngesikhathi kufakwa ama-HDPE geomembranes, ukwakheka kwemibotshana eyenziweyo kufanele kugwenywe; lapho izinga lokushisa elizungezile liphansi, i-membrane kufanele idonswe iqine futhi ibekwe eyekile ngangokunokwenzeka.
7. Uma ukufakwa kwe-HDPE geomembrane kuqediwe, ukuhamba ngezinyawo phezu kwe-membrane kanye nokuhamba kwezinsimbi kufanele kuncishiswe. Akukho izinto ezingadala ukulimala ku-HDPE membrane—kungaba ngokubekwa phezu kwayo noma ukuthwalwa kuyo—ezingalethwa phezu kwe-membrane, ukuze kugwenywe ukulimala okungazelelwe.
