- Litšobotsi
- Ts'ebetso e ntle ea anti-seepage: E na le matla a tlase haholo a ho kenella 'me e ka thibela ka nepo ho kenella ha metsi. E na le phello e ntle ea thibelo khahlanong le metsi, oli, tharollo ea lik'hemik'hale, joalo-joalo. Coefficient ea anti-seepage e ka fihla ho 1×10⁻¹²cm/s to 1×10⁻¹⁷cm/s, e ka finyellang litlhoko tsa anti-seepage tsa merero e mengata. .
- Botsitso bo matla ba lik'hemik'hale: E na le khanyetso e ntle ea asiti le alkali le ho hanyetsa kutu. E ka dula e tsitsitse dibakeng tse fapaneng tsa dikhemikhale mme ha e hoholehe habonolo ke dikhemikhale tse mobung. E ka hanela ho bola ha likarolo tse itseng tsa acid, alkali, letsoai le litharollo tse ling.
- Ho hanyetsa mocheso o tlase: E ntse e ka boloka maemo a matle le thepa ea mochini sebakeng sa mocheso o tlase. Mohlala, li-geomembrane tsa boleng bo holimo tsa polyethylene tse boreleli li ntse li na le elasticity e itseng ho -60 ℃ ho ea ho -70 ℃ 'me ha ho bonolo ho robeha habonolo.
- Kaho e bonolo: Bokaholimo bo boreleli 'me coefficient ea likhohlano e nyane, e loketseng ho beoa libakeng tse fapaneng le metheong. E ka kopanngoa ka ho tjheseletsa, ho kopanya le mekhoa e meng. Lebelo la kaho le potlakile mme boleng bo bonolo ho laola.
Mokhoa oa Tlhahiso
- Mokhoa oa ho bopa oa Extrusion blow: Thepa e tala ea polima e futhumatsoa ho fihlela e qhibiliha ebe e ntšoa ka extruder ho etsa sekheo sa tubular. Ka mor'a moo, moea o hatelitsoeng o butsoela ka har'a tube e se nang letho ho etsa hore e atolohe le ho khomarela hlobo bakeng sa ho pholile le ho bopa. Qetellong, geomembrane e boreleli e fumanoa ka ho itšeha. Geomembrane e hlahisoang ke mokhoa ona e na le botenya bo lekanang le thepa e ntle ea mochine.
- Mokhoa oa khalendara: Thepa e tala ea polima e futhumatsoa ebe e atolosoa le ho otlolloa ka lirolara tse ngata tsa calender ho etsa filimi e nang le botenya le bophara bo itseng. Kamora ho pholile, ho fumanoa geomembrane e boreleli. Ts'ebetso ena e na le katleho e phahameng ea tlhahiso le bophara ba sehlahisoa se pharaletseng, empa ho tšoana ha botenya ho batla ho fokola.
Libaka tsa Kopo
- Morero oa paballo ea metsi: E sebelisoa bakeng sa kalafo e thibelang ho sutuha ha libaka tsa ho baballa metsi joalo ka matamo, matamo le likanale. E ka thibela ka nepo ho tsoa ha metsi, ea ntlafatsa polokelo ea metsi le katleho ea phetiso ea merero ea ho baballa metsi, le ho lelefatsa bophelo ba ts'ebeletso ea morero.
- Thotobolo ya matlakala: Jwaloka lesela le thibelang ho kgephoha ha mobu tlase le lehlakoreng la thotobolo, le thibela lehlahiswa ho silafatsa mobu le metsi a ka tlasa mobu le ho sireletsa tikoloho e e potileng ya tikoloho.
- Ho haha metsi a sa keneleng metsi: E sebelisoa e le lera le sa keneleng metsi marulelong, kamoreng e ka tlaase, kamore ea ho hlapela le likarolo tse ling tsa mohaho ho thibela ho kenella ha metsi a pula, metsi a ka tlas'a lefatše le mongobo o mong mohahong le ho ntlafatsa ts'ebetso ea ho thibela metsi ea mohaho.
- Sebaka sa Maiketsetso: E sebelisoa bakeng sa ho thibela metsi a matša a maiketsetso, matamo a naha, libaka tsa metsi tsa lebala la kolofo, joalo-joalo, ho boloka botsitso ba 'mele oa metsi, ho fokotsa tahlehelo ea ho lutla ha metsi, le ho fana ka motheo o motle bakeng sa popo ea naha.
Litlhaloso le Lipontšo tsa Theknoloji
- Litlhaloso: Botenya ba geomembrane e boreleli hangata bo pakeng tsa 0.2mm le 3.0mm, 'me bophara hangata bo pakeng tsa 1m le 8m, e ka etsoang ho latela litlhoko tsa merero e fapaneng.
- Matšoao a tekheniki: Ho kenyelletsa matla a ho tiea, bolelele nakong ea khefu, matla a ho tabola ka lehlakoreng le letona, ho hanyetsa khatello ea hydrostatic, jj. matla a pakeng tsa 50N/mm le 300N/mm, mme khatello ea hydrostatic e pakeng tsa 0.5MPa le 3.0MPa.
