High-density polyethylene (HDPE) geomembranes bakeng sa lithōle

Li-geomembrane tsa polyethylene tse phahameng haholo (HDPE) bakeng sa lithōle Setšoantšo se bontšitsoeng

Tlhaloso e Khutšoanyane:

HDPE geomembrane liner e entsoe ka thepa ea polyethylene polymer. Mosebetsi oa eona o ka sehloohong ke ho thibela ho lutla ha metsi le mouoane oa khase. Ho latela thepa e tala ea tlhahiso, e ka aroloa ka HDPE geomembrane liner le EVA geomembrane liner.

Tlhaloso ea Lihlahisoa

HDPE geomembrane ke e 'ngoe ea lisebelisoa tsa geosynthetic, e na le khanyetso e ntle ea khatello ea tikoloho, ho hanyetsa mocheso o tlase, ho thibela botsofali, ho hanyetsa kutu, hammoho le mefuta e mengata ea mocheso le bophelo bo bolelele ba ts'ebeletso, e sebelisoang haholo ho se keng ha qojoa ha litšila tsa malapeng, litšila tse tiileng. tšilafalo ea mobu, ho se hloeke ha polante ea likhoerekhoere, ho se be le metsi a maiketsetso a letša, kalafo ea mehatla le merero e meng e sa tsitsang.

Litšobotsi tsa Ts'ebetso

1. Ha e na li-additives tsa lik'hemik'hale, ha e kene kalafo ea mocheso, ke thepa ea mohaho e nang le tikoloho.
2. E na le thepa e ntle ea mochini, ho kenella hantle ha metsi, 'me e khona ho hanela kutu, ho thibela botsofali.
3. Ka khanyetso e matla e patiloeng, ho hanyetsa kutu, sebopeho sa fluffy, se nang le ts'ebetso e ntle ea drainage.
4. E na le coefficient e ntle ea khohlano le matla a tsitsipano, e nang le ts'ebetso ea matlafatso ea geotechnical.
5. Ka ho itšehla thajana, ho hloekisa, ho ntša metsi, tšireletso, botsitso, ho matlafatsa le mesebetsi e meng.
6. E ka ikamahanya le motheo o sa lekaneng, e ka hanela tšenyo ea kaho ea ka ntle, creep e fetoha e nyenyane.
7. Tsoelo-pele ka kakaretso e ntle, boima bo bobebe, kaho e loketseng.
8. Ke thepa e khonang ho phunyeletsa, kahoo e na le ts'ebetso e ntle ea ho itšehla thajana ea filtration, khanyetso e matla ea ho phunya, kahoo e na le ts'ebetso e ntle ea tšireletso.
