Cov geomembrane ntxhib
Kev Piav Qhia Luv:
Cov geomembrane ntxhib feem ntau yog ua los ntawm cov polyethylene siab (HDPE) lossis polypropylene ua cov khoom siv raw, thiab raug kho los ntawm cov khoom siv tsim khoom thiab cov txheej txheem tsim khoom tshwj xeeb, nrog rau cov qauv ntxhib lossis pob ntawm qhov chaw.

Hom
Ib qho geomembrane ntxhib:Nws yog ntxhib ntawm ib sab thiab du ntawm sab tod. Hauv qhov kev tsim kho qhov project tiv thaiv kev ntws, sab ntxhib feem ntau yog tig mus rau saum toj kom kov lub geotextile kom ua tiav cov nyhuv tiv thaiv kev plam.
Ob chav-ntxhib geomembrane:Ob sab yog ntxhib. Thaum siv, ob sab saud thiab sab qis tuaj yeem sib cuag nrog geotextile rau lub hom phiaj tiv thaiv kev plam, thiab nws tau siv dav.
Cov duab geomembrane:Muaj cov pob sib npaug zos rau ib sab lossis ob sab. Cov pob no faib sib npaug zos thiab zoo nkauj. Nws tuaj yeem siv rau hauv cov haujlwm tiv thaiv kev ntws ntawm qhov nqes hav los ua lub luag haujlwm tiv thaiv kev ntws, tiv thaiv kev plam thiab tiv thaiv kev ua qias tuaj.
Cov yam ntxwv ntawm kev ua tau zoo
Kev Sib Txhuam Siab:Cov qauv ntxhib lossis cov pob ntawm qhov chaw tuaj yeem ua rau muaj kev sib txhuam nrog lwm cov ntaub ntawv (xws li geotextiles, av, thiab lwm yam), tiv thaiv cov geomembrane kom tsis txhob swb ntawm cov qhov ntxhab lossis cov chaw ntsug, thiab txhim kho kev ruaj khov ntawm qhov project. Nws yog qhov tsim nyog rau cov haujlwm tiv thaiv kev ntws ntawm cov qhov ntxhab xws li cov chaw pov tseg thiab cov qhov dej ntws.
Kev Ua Zoo Tiv Thaiv Kev Ntsws:Ib yam li cov geomembranes du, nws muaj cov coefficient permeability qis heev thiab tuaj yeem thaiv cov kua nkag mus, tiv thaiv kev poob dej lossis kev sib kis ntawm cov pa phem. Nws tuaj yeem siv rau hauv kev txuag dej, kev tiv thaiv ib puag ncig thiab lwm yam haujlwm uas muaj cov kev xav tau tiv thaiv kev seepage siab.
Kev Ruaj Ntseg Tshuaj:Nws muaj kev ruaj khov tshuaj lom neeg zoo heev thiab tuaj yeem tiv taus qhov xeb ntawm ntau dua 80 hom kua qaub thiab alkali tshuaj lom neeg xws li kua qaub, alkalis thiab ntsev. Nws tuaj yeem tswj tau qhov ua tau zoo hauv cov haujlwm engineering nrog ntau yam tshuaj lom neeg ib puag ncig, xws li hauv kev kho dej phwj tuaj thiab cov thoob dej tshuaj lom neeg.
Kev Ua Haujlwm Tiv Thaiv Kev Laus:Nws muaj peev xwm tiv thaiv kev laus, tiv thaiv ultraviolet thiab tiv thaiv kev lwj, thiab siv tau rau hauv kev lag luam. Lub neej ua haujlwm ntawm cov khoom siv tuaj yeem ncav cuag 50 - 70 xyoo, uas tuaj yeem muab kev lees paub zoo rau cov haujlwm tiv thaiv kev ntws mus sij hawm ntev.
Lub Zog Kho Tshuab Siab:Nws muaj lub zog tensile siab, tiv taus kev rhuav thiab tiv taus kev tho, nrog rau kev ywj pheej zoo heev thiab kev hloov pauv. Nws tuaj yeem hloov kho rau cov chaw puag ncig uas nthuav dav lossis ntsws thiab kov yeej qhov tsis sib npaug ntawm qhov chaw puag ncig.
Cov Xwm Txheej ntawm Daim Ntawv Thov
Cov Haujlwm Tiv Thaiv Ib Puag Ncig:Hauv cov chaw pov tseg, nws yog siv rau kev tiv thaiv kev ntws ntawm cov toj roob hauv pes ib puag ncig thiab hauv qab kom tiv thaiv cov dej khib nyiab los ntawm kev xau thiab ua rau cov av thiab dej hauv av qias neeg. Nws kuj tseem siv tau rau kev tiv thaiv kev ntws ntawm cov pas dej leaching heap thiab cov ntaub tailings hauv kev lag luam mining kom tsis txhob muaj cov tshuaj lom neeg xau.
Cov Haujlwm Txuag Dej:Nws yog siv rau qhov nqes hav tiv thaiv kev ntws ntawm cov pas dej, pas dej loj, cov kwj dej, thiab lwm yam, uas tuaj yeem tiv thaiv dej xau. Lub caij no, nyob rau hauv qhov chaw siab, nws cov kev ua tau zoo tiv thaiv kev plam tuaj yeem ua kom muaj kev ruaj khov ntawm geomembrane.
Cov Haujlwm Thauj Mus Los:Nws siv tau rau kev tiv thaiv kev ntws ntawm cov qhov av ntawm txoj kev loj thiab kev tsheb ciav hlau, nrog rau kev tiv thaiv cov toj roob hauv pes nrog cov kev cai tshwj xeeb tiv thaiv kev plam thiab tiv thaiv kev ntws.
Cov Haujlwm Ua Liaj Ua Teb:Nws yog siv rau hauv kev tiv thaiv kev seepage ntawm cov roob thiab hauv qab ntawm cov pas dej aquaculture, uas tuaj yeem tswj cov dej theem, tiv thaiv dej xau thiab av qias neeg, thiab kuj yooj yim rau kev tsim kho thiab kev saib xyuas cov chaw aquaculture.
