1. HDPE Geomembrane ke eng?
HDPE Geomembrane, eo lebitso la eona le felletseng e leng "High-Density Polyethylene Geomembrane," ke thepa e sa keneleng metsi le e thibelang metsi e hlahisoang ho sebelisoa (bohareng) bo phahameng ba polyethylene resin.Boitsebiso bo na le khanyetso e babatsehang ea ho senya khatello ea tikoloho, ho hanyetsa mocheso o tlaase, ho hanyetsa botsofali le ho hanyetsa kutu, hammoho le mefuta e mengata ea mocheso oa tšebeliso (-60- + 60) le bophelo bo bolelele ba tšebeletso ea lilemo tse 50.E sebelisoa haholo mererong e khahlanong le seepage joalo ka ho thibela litšila tsa lithōle tsa bophelo, ho thibela litšila tse nang le litšila tse tiileng, ho thibela metsi a likhoerekhoere ho thibela metsi a litšila, ho thibela metsi a maiketsetso a letša le ho phekola mesela.

II.Mekhoa le Lisebelisoa tsa HDPE Geomembrane Lefapheng la Lithōle
Hajoale, lithōle ke mokhoa o sebelisoang ka ho fetesisa oa ho phekola litšila tse tiileng le lithōle tsa ka tlung, tse khetholloang ka theko e tlase, matla a maholo a ho sebetsa, le ts'ebetso e bonolo.E 'nile ea sebelisoa haholo linaheng tse ngata le libakeng tse ngata' me e bile mokhoa o ka sehloohong oa phekolo bakeng sa litšila tsa malapa linaheng tse ngata tse tsoetseng pele.
Polyethylene geomembrane ea polyethylene ea boleng bo phahameng ke eona e sebelisoang ka ho fetisisa e thibelang metsi ho pota-pota ka har'a lithōle.HDPE Geomembrane e hlahella har'a lihlahisoa tsa letoto la polyethylene ka matla a eona a phahameng a phahameng, thepa ea lik'hemik'hale e tsitsitseng, le ts'ebetso e ntle ea ho thibela botsofali, 'me e ananeloa haholo ke baqapi le beng ba liindasteri tsa ho lahlela lithōle.
Hangata lithōle li kenyelletsa bothata ba leachate e nang le lintho tse chefo haholo le tse kotsi, lik'hemik'hale tse kotsi le mathata a mang.Lintho tse sebelisoang ho boenjiniere li na le maemo a ts'ebeliso a rarahaneng haholo, ho kenyelletsa lintlha tsa matla, maemo a tlhaho, mecha ea litaba, nako, joalo-joalo, hammoho le lintlha tse fapaneng tse phahamisitsoeng.Boleng ba liphello tse khahlanong le seepage ka ho toba bo khetholla boleng ba boenjiniere, 'me bophelo ba tšebeletso ea geomembrane e boetse e le eona ntho e ka sehloohong e khethollang bophelo ba boenjiniere.Ka hona, lisebelisoa tse khahlanong le seepage tse sebelisoang bakeng sa li-landfill liner li tlameha ho ba le ts'ebetso e ntle ea ho thibela metsi, ho senyeha ha lintho tse phelang hantle, le ts'ebetso e ntle ea antioxidation, har'a lintlha tse ling.
Kamora lilemo tse ngata tsa lipatlisiso le boithuto setsing sa lipatlisiso sa khamphani ea rona sa geomembrane, geomembrane e sebelisoang tsamaisong ea anti-seepage bakeng sa libaka tsa ho lahlela lithōle ha ea tlameha ho ipapisa le maemo a hajoale a naha le a machabeng a tekheniki empa hape le ho fihlela litlhoko tse latelang:
(1) Botenya ba HDPE Geomembrane ha boa lokela ho ba ka tlase ho 1.5mm.Botenya bo lekanya ka ho toba boemo ba khatello ea maikutlo, ho tšoarella, ho hanyetsa ho phunya, le botsitso ba tsamaiso ea liner.

(5) HDPE Geomembrane e lokela ho khona ho boloka ts'ebetso ea eona e ntle ea anti-seepage ka nako e telele (ke hore, bonyane lilemo tse 50), e ka netefatsang bophelo ba nako e telele ea tšebeletso ea tsamaiso ea liner.
Ntle le litlhoko tse ka holimo, HDPE Geomembrane e sebelisoang libakeng tsa ho lahlela mobu le eona e lokela ho etsoa le ho kenngoa ho ea ka maemo a khethehileng a sebaka sa ho qhala, joalo ka boholo ba sona, sebaka, boemo ba leholimo, geology, hydrology, joalo-joalo. e sebakeng se nang le litafole tse phahameng tsa metsi, e ka 'na ea hloka ho raloa ka mokhoa oa ho kopanya habeli kapa mokhoa oa ho bokella leachate o ka thibelang ho silafala ha metsi a ka tlas'a lefatše.
Ka kakaretso, tšebeliso ea HDPE Geomembrane boenjiniere ba ho lahlela lithōle ke mokhoa o sebetsang oa ho netefatsa polokeho le ts'ireletso ea tikoloho ea lithōle tsa sejoale-joale.Ka ho khetha thepa e nepahetseng, ho rala litsamaiso tse nepahetseng, le ho latela mekhoa e nepahetseng ea ho kenya le ho lokisoa, lithōle li ka ba tse sireletsehileng, tse sebetsang hantle le tse tšoarellang.
