Geomembrane liners yog cov ntaub ntawv tseem ceeb uas siv rau hauv ntau yam kev tsim kho thiab ib puag ncig kev ua haujlwm los tiv thaiv kev nkag mus ntawm cov kua thiab roj. Ntawm ntau hom geomembrane liners muaj nyob rau hauv kev ua lag luam, HDPE (High-Density Polyethylene), PVC (Polyvinyl Chloride), thiab LLDPE (Linear Low-Density Polyethylene) geomembrane liner tau dav siv. Txhua homgeomembrane linermuaj nws cov khoom tshwj xeeb thiab kev siv, ua rau nws tseem ceeb kom nkag siab qhov sib txawv ntawm lawv.
HDPE geomembrane lineryog tsim los ntawm high-density polyethylene, thermoplastic polymer paub txog nws cov khoom muaj zog thiab ruaj khov. HDPE liners feem ntau yog siv rau hauv cov ntawv thov uas yuav tsum muaj tshuaj tiv thaiv thiab UV tiv thaiv, xws li hauv cov chaw pov tseg, kev ua haujlwm tsuas, thiab cov pas dej ua ke. Cov khoom siv lub zog tensile siab thiab puncture kuj ua rau nws tsim nyog rau cov haujlwm uas yuav tsum tau ua kom ntev ntev thiab kev tiv thaiv ib puag ncig.
PVC geomembrane liner, ntawm qhov tod tes, yog tsim los ntawm polyvinyl chloride, hluavtaws hluavtaws polymer paub txog nws yooj yim thiab tsis kam mus rau tshuaj. PVC liners feem ntau yog siv rau hauv daim ntawv thov qhov yooj yim thiab weldability yog qhov tseem ceeb, xws li hauv cov dej ntim, cov pas dej zoo nkauj, thiab cov pas dej ua liaj ua teb. PVC geomembrane liners paub txog lawv qhov yooj yim ntawm kev teeb tsa thiab muaj peev xwm ua tau raws li qhov tsis sib xws, ua rau lawv muaj kev xaiv nrov rau ntau yam kev tiv thaiv.
LLDPE geomembrane lineryog tsim los ntawm linear low-density polyethylene, ib tug saj zawg zog thiab resilient khoom paub txog nws puncture kuj thiab elongation zog. LLDPE liners feem ntau yog siv rau hauv daim ntawv thov qhov yooj yim thiab elongation yog ib qho tseem ceeb, xws li nyob rau hauv floating npog, theem ob, thiab kwj dej liner. Cov khoom muaj peev xwm ua tau raws li lub substrate thiab tiv thaiv punctures ua rau nws haum rau tej yaam num uas yuav tsum tau ib tug siab ntawm yooj thiab durability.
Thaum muab piv HDPE, PVC, thiab LLDPE geomembrane liners, ntau qhov sib txawv tseem ceeb tau pom meej. HDPE liners paub txog lawv lub zog tensile siab thiab tshuaj tiv thaiv, ua rau lawv tsim nyog rau cov ntawv thov uas yuav tsum tau ua kom ntev ntev. PVC liners muaj nuj nqis rau lawv qhov yooj yim thiab weldability, ua rau lawv zoo tagnrho rau cov haujlwm uas yuav tsum tau yooj yim installation thiab ua raws li qhov chaw tsis sib xws. LLDPE liners tau txais txiaj ntsig rau lawv qhov yooj yim thiab puncture tsis kam, ua rau lawv haum rau cov ntawv thov uas xav tau qib siab ntawm kev ua haujlwm siab thiab elongation.
Hauv kev xaus, kev xaiv ntawm HDPE, PVC, thiab LLDPE geomembrane liner nyob ntawm qhov tshwj xeeb ntawm qhov project. Txhua homgeomembrane linermuaj cov khoom tshwj xeeb thiab qhov zoo, ua rau nws tseem ceeb rau kev txiav txim siab txog yam xws li tshuaj lom neeg tsis kam, yoog raws, thiab kev sib tsoo thaum xaiv cov khoom tsim nyog rau ib daim ntawv thov tshwj xeeb. Los ntawm kev nkag siab txog qhov sib txawv ntawm HDPE, PVC, thiab LLDPE geomembrane liners, engineers thiab project managers muaj peev xwm txiav txim siab kom paub tseeb tias qhov ua tau zoo thiab ntev ntawm lawv cov kev tuav pov hwm thiab kev tiv thaiv ib puag ncig.
