Li-geomembrane tsa polyethylene e nang le sekgahla se phahameng (HDPE) bakeng sa ho lahla lithōle

Tlhaloso e Khutšoanyane:

Mochini oa geomembrane oa HDPE o bōpiloe ka ho phatloha ho tsoa thepa ea polyethylene polymer. Mosebetsi oa oona o ka sehloohong ke ho thibela ho lutla ha metsi le ho fetoha ha mouoane ha khase. Ho ea ka lihlahisoa tse tala tsa tlhahiso, e ka aroloa ka mochini oa geomembrane oa HDPE le mochini oa geomembrane oa EVA.

2. E na le thepa e ntle ea mechini, e kenella hantle metsing, 'me e khona ho hanela mafome, e thibela botsofali.
3. Ka khanyetso e matla e patiloeng, khanyetso ea mafome, sebopeho se boreleli, ka ts'ebetso e ntle ea ho ntša metsi.
4. E na le coefficient e ntle ea khohlano le matla a ho thapolla, ka ts'ebetso ea matlafatso ea geotechnical.
5. Ka ho itšehla thajana, ho sefa, ho ntsha metsi, tshireletso, botsitso, matlafatso le mesebetsi e meng.
6. E ka ikamahanya le motheo o sa lekanang, e ka hanela tshenyo ya kaho ya kantle, ho thekesela ho ba honyenyane.
7. Ho tswela pele ka kakaretso ho molemo, boima bo bobebe, kaho e bonolo.
8. Ke thepa e kenang ka metsing, kahoo e na le ts'ebetso e ntle ea ho itšehla thajana, e hanyetsa ho phunyeha ho matla, kahoo e na le ts'ebetso e ntle ea tšireletso.
