Geomembrane yog ib qho tseem ceeb geosynthetic cov ntaub ntawv feem ntau siv los tiv thaiv cov infiltration ntawm cov kua los yog gases thiab muab ib tug barrier lub cev. Nws feem ntau yog ua los ntawm yas zaj duab xis, xws li high-density polyethylene (HDPE), low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), polyvinyl chloride (PVC), ethylene vinyl acetate (EVA) lossis ethylene vinyl. acetate modified asphalt (ECB), thiab lwm yam. Nws yog qee zaum siv ua ke nrog cov ntaub tsis-woven lossis lwm hom geotextiles los txhim kho nws kev ruaj ntseg thiab kev tiv thaiv thaum lub sij hawm installation.
Geomembranes muaj ntau yam kev siv hauv ntau qhov chaw, suav nrog tab sis tsis txwv rau cov hauv qab no:
1. Kev tiv thaiv ib puag ncig:
Qhov chaw pov tseg: tiv thaiv cov dej xau thiab cov pa phem ntawm cov dej hauv av thiab av.
Kev puas tsuaj thiab pov tseg cov khoom pov tseg: tiv thaiv kom tsis txhob muaj cov khoom tsis zoo hauv cov chaw khaws cia thiab kho.
Tso tseg mines thiab tailings cia qhov chaw: tiv thaiv cov minerals lom thiab dej khib nyiab los ntawm infiltrating ib puag ncig.
2. Kev txuag dej thiab kev tswj xyuas dej:
Reservoirs, dams, thiab channels: txo cov dej infiltration poob thiab txhim kho kev siv dej kom zoo.
Cov pas dej cuav, cov pas dej da dej, thiab cov pas dej da dej: tswj cov qib dej, txo cov evaporation thiab to.
Agricultural irrigation system: tiv thaiv dej poob thaum thauj.
3. Lub tsev thiab infrastructure:
Tunnels thiab hauv qab daus: tiv thaiv cov dej hauv av.
Underground engineering thiab subway tej yaam num: Muab cov dej tsis sib haum.
Ru tsev thiab hauv qab daus waterproofing: tiv thaiv kom tsis txhob ya raws nkag mus rau hauv lub tsev qauv.
4. Petroleum thiab chemical kev lag luam:
Cov roj cia tso tsheb hlau luam thiab cov chaw khaws tshuaj lom neeg: tiv thaiv kom tsis txhob muaj kuab paug ib puag ncig.
5. Kev ua liaj ua teb thiab kev nuv ntses:
Aquaculture pas dej: tswj dej kom zoo thiab tiv thaiv kom tsis muaj zaub mov.
Ua liaj ua teb thiab tsev cog khoom: ua ib qho kev thaiv dej los tswj kev faib dej thiab cov khoom noj.
6. Mines:
Heap leaching tank, dissolution tank, sedimentation tank: tiv thaiv cov tshuaj tov dej thiab tiv thaiv ib puag ncig.
Kev xaiv thiab siv cov geomembranes yuav raug txiav txim siab raws li cov kev thov tshwj xeeb thiab cov kev cai ib puag ncig, xws li cov khoom siv, tuab, qhov loj me, thiab tshuaj tiv thaiv. Yam xws li kev ua tau zoo, durability, thiab nqi.
