Geomembrane e boreleli
Tlhaloso e Khutšoanyane:
Hangata geomembrane e boreleli e entsoe ka thepa e le 'ngoe ea polymer, joalo ka polyethylene (PE), polyvinyl chloride (PVC), jj. Bokaholimo ba eona bo boreleli ebile bo bataletse, ha bo na sebopeho se totobetseng kapa likaroloana.
Sebopeho sa motheo
Hangata geomembrane e boreleli e entsoe ka thepa e le 'ngoe ea polymer, joalo ka polyethylene (PE), polyvinyl chloride (PVC), jj. Bokaholimo ba eona bo boreleli ebile bo bataletse, ha bo na sebopeho se totobetseng kapa likaroloana.
- Litšobotsi
- Tshebetso e ntle ya ho thibela ho dutla ha metsi: E na le ho kenella ho tlase haholo mme e ka thibela ho kenella ha metsi ka katleho. E na le phello e ntle ya thibelo kgahlanong le metsi, oli, ditharollo tsa dikhemikhale, jj. Palo e thibelang ho dutla ha metsi e ka fihla ho 1×10⁻¹²cm/s ho isa ho 1×10⁻¹⁷cm/s, e leng se ka fihlelang ditlhoko tsa ho thibela ho dutla ha metsi tsa diporojeke tse ngata.
- Ho tsitsa ha lik'hemik'hale ho matla: E na le khanyetso e ntle ea asiti le alkali le khanyetso ea mafome. E ka lula e tsitsitse libakeng tse fapaneng tsa lik'hemik'hale 'me ha e senyehe habonolo ke lik'hemik'hale tse mobung. E ka hanela mafome a metsoako e itseng ea asiti, alkali, letsoai le litharollo tse ling.
- Ho hanyetsa mocheso o tlase hantle: E ntse e ka boloka ho tenyetseha ho hotle le thepa ea mechini tikolohong e mocheso o tlase. Mohlala, li-geomembrane tse ling tse boreleli tsa polyethylene tsa boleng bo holimo li ntse li na le ho tenyetseha ho itseng ho tloha ho -60℃ ho isa ho -70℃ 'me ha li bonolo ho robeha.
- Kaho e bonolo: Bokaholimo bo boreleli 'me coefficient ea khohlano e nyane, e leng se loketseng ho beoa libakeng tse fapaneng le metheong. E ka hokahanngoa ka ho tjheseletsa, ho kopanya le mekhoa e meng. Lebelo la kaho le potlakile 'me boleng bo bonolo ho bo laola.
Tshebetso ea Tlhahiso
- Mokhoa oa ho bopa ka ho ntša metsi: Thepa e tala ea polymer e futhumatsoa ho fihlela e qhibilihisoa ebe e ntšoa ka sesebelisoa sa ho ntša metsi ho etsa sekheo sa tšubuhlellano. Ebe moea o hatelletsoeng o butsoeloa ka har'a sekheo sa tšubuhlellano ho etsa hore se atolohe 'me se khomarele hlobo bakeng sa ho pholisa le ho bopa. Qetellong, geomembrane e boreleli e fumanoa ka ho seha. Geomembrane e hlahisoang ke mokhoa ona e na le botenya bo lekanang le thepa e ntle ea mechini.
- Mokhoa oa ho etsa calender: Thepa e tala ea polymer e futhumatsoa ebe e ntšoa le ho otlolloa ka lirolo tse ngata tsa calender ho etsa filimi e nang le botenya le bophara bo itseng. Kamora ho pholile, geomembrane e boreleli ea fumanoa. Ts'ebetso ena e na le katleho e phahameng ea tlhahiso le bophara bo pharaletseng ba sehlahisoa, empa ho tšoana ha botenya ho fokola haholo.
Masimo a Kopo
- Morero oa paballo ea metsi: O sebelisetsoa ho phekola libaka tsa paballo ea metsi tse kang matamo a metsi, matamo le likanale. O ka thibela ho lutla ha metsi ka katleho, oa ntlafatsa polokelo ea metsi le bokhoni ba ho tsamaisa metsi ba merero ea paballo ea metsi, le ho atolosa bophelo ba tšebeletso ea projeke.
- Ho lahla lithōle: Kaha ke setshelo se thibelang ho dutla ha metsi tlase le ka lehlakoreng la ho lahla lithōle, se thibela ho dutla ha metsi ho silafatsa mobu le metsi a ka tlas'a lefatše 'me se sireletsa tikoloho e potolohileng.
- Moaho o sa keneleng metsi: O sebediswa e le lera le sa keneleng metsi marulelong, mokatong o ka tlase, ka kamoreng ya ho hlapela le dikarolong tse ding tsa moaho ho thibela ho kenella ha metsi a pula, metsi a ka tlasa lefatshe le mongobo o mong ka hara moaho le ho ntlafatsa tshebetso ya moaho e sa keneleng metsi.
- Sebaka sa maiketsetso: Se sebelisetsoa ho thibela ho dutla ha matša a maiketsetso, matamo a tlhaho, libaka tsa metsi tsa lebala la kolofo, jj., ho boloka botsitso ba metsi, ho fokotsa tahlehelo ea metsi a lutlang, le ho fana ka motheo o motle oa ho theha sebaka sa tlhaho.
Litlhaloso le Matšoao a Tekheniki
- 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 leng se ka fetoloang ho latela litlhoko tsa merero e fapaneng.
- Matšoao a tekheniki: Ho kenyeletsoa matla a ho thaepa, ho lelefala ha ho robeha, matla a ho taboha ka lehlakoreng le letona, ho hanyetsa khatello ea hydrostatic, jj. Matla a ho thaepa ka kakaretso a pakeng tsa 5MPa le 30MPa, ho lelefala ha ho robeha ho pakeng tsa 300% le 1000%, matla a ho taboha ka lehlakoreng le letona a pakeng tsa 50N/mm le 300N/mm, 'me ho hanyetsa khatello ea hydrostatic ho pakeng tsa 0.5MPa le 3.0MPa.
