Kev Xaiv Cov Khoom Siv thiab Cov Txheej Txheem Tsim Khoom:
HDPE (High-Density Polyethylene) Geomembranes: Ib yam khoom siv uas feem ntau siv thiab paub txog nws txoj kev tiv thaiv corrosion zoo heev thiab tiv thaiv kev laus, ua rau nws tsim nyog rau feem ntau ntawm cov liaj teb yug tsiaj.
Kev Xaiv Txheej Txheem: Geomembranes tsim los ntawm cov txheej txheem cua tshuab. ua kom pom tseeb ntau dua qhov tuab thiab cov khoom tensile, nrog rau kev tiv thaiv zoo dua; cov uas tsim los ntawm cov txheej txheem calendering muaj qhov tiav du, txawm hais tias lawv qhov tuab sib xws yuav tsis sib xws me ntsis.
Kev Xav Txog Qhov Zoo thiab Cov Qauv: Muab qhov tseem ceeb rau cov geomembranes uas ua raws li cov qauv hauv tebchaws (piv txwv li, GB / T 17643-2011) lossis cov qauv kev tsim kho hauv nroog (piv txwv li, CJ / T 234-2006) kom ntseeg tau tias cov khoom xws li kev tiv thaiv kev seepage, lub zog tensile, thiab kev tiv thaiv corrosion ua tau raws li cov qauv xav tau.
Tsis txhob siv cov geomembranes uas ua los ntawm cov khoom siv rov ua dua tshiab; hloov chaw, muab qhov tseem ceeb rau cov uas ua los ntawm 100% cov khoom tshiab kom lav qhov khoom siv tau ntev thiab muaj kev nyab xeeb.
Qhov tuab yog qhov qhia tseem ceeb rau kev tiv thaiv kev ntws thiab kev ua haujlwm ntev. Cov khoom uas nyias dhau yuav yooj yim rhuav, thaum cov khoom uas tuab dhau yuav ua rau muaj kev pov tseg tsis tsim nyog; yog li ntawd, qhov tuab yuav tsum tau xaiv raws li daim ntawv thov kev yug me nyuam tshwj xeeb:
Cov Pas Dej Ua Liaj Ua Teb Me, Cov Pas Dej Ntsug (Qhov tob ntawm dej ≤ 1.2m) thiab Cov Pas Dej Yug Me Nyuam: Xaiv 0.5–0.75mm.
Cov Pas Dej Ntses thiab Cov Pas Dej Cws Txheem (Qhov tob ntawm dej 1.2–2.5m): Xaiv 1.0–1.5mm rau qhov sib piv zoo tshaj plaws ntawm tus nqi thiab kev ua tau zoo.
Cov Pas Dej Sib Sib (Qhov dej tob ≥ 2.5m) thiab Cov Chaw Yug Me Nyuam Tshwj Xeeb (piv txwv li, cov vaub kib mos mos, cov ntses crayfish): Xaiv 1.5–2.0 hli rau kev tiv thaiv kev tho.
Cov Qhov Pov Tseg/Cov Qhov Quav Quav thiab Cov Khib Nyhiab ntawm Cov Tsiaj Txhu thiab Nqaij Qaib Vim tias qhov chaw muaj kuab paug heev thiab yooj yim raug cuam tshuam los ntawm cov khoom tawv, qhov tuab tsawg kawg nkaus ntawm 1.0 hli yog qhov yuav tsum tau ua; qhov tuab ntawm 1.5 hli yog qhov pom zoo heev.
Cov Pas Dej thiab Cov kwj dej ywg dej Rau qhov tob ntawm dej tsawg dua 2m, xaiv 0.5–0.75mm; rau qhov tob ntawm dej ntawm 2m thiab 4m, xaiv 0.75–1.0mm; rau cov pas dej loj, xaiv 1.5mm lossis tuab dua.
