Qhov zoo thiab qhov tsis zoo ntawm HDPE geomembrane thiab PVC geomembrane nyob rau hauv lub reservoir
Thaum nws los txog rau kev tsim lub reservoir, ib qho ntawm cov ntaub ntawv tseem ceeb tshaj plaws uas yuav tsum tau xav txog yog cov geomembrane liner uas yuav ua kom cov dej ntim tau thiab tiv thaiv cov xau. Muaj ntau ntau hom geomembranes muaj, tab sis PVC (polyvinyl chloride) thiab HDPE (high-density polyethylene) yog ob qho kev xaiv ntau tshaj plaws. Yog li qhov twg yog qhov zoo dua rau kev tsim lub reservoir - PVC lossis HDPE geomembrane?
PVC Geomembrane muaj
PVC geomembrane yog tsim los ntawm ib hom yas uas paub txog nws qhov yooj thiab durability. Nws tiv taus UV rays, tshuaj, thiab huab cua kub, txhais tau tias nws tuaj yeem tiv taus cov ntsiab lus ntev ntev yam tsis poob nws lub zog lossis kev ncaj ncees.
Ib qho ntawm qhov zoo tshaj plaws ntawm PVC geomembrane yog nws qhov yooj yim ntawm kev teeb tsa. Nws tuaj yeem welded ua ke siv cov cua kub los yog RF (radiofrequency) induction vuam cov tswv yim, thiab nws feem ntau muaj nyob rau hauv qhov dav dav, ua kom nws yooj yim dua los npog thaj tsam loj sai thiab nrog cov seams tsawg.
Lwm qhov zoo ntawm PVC geomembrane yog tias nws tsis tshua muaj punctures thiab kua muag dua li lwm hom geomembranes. Qhov no txhais tau hais tias nws tsis tshua muaj peev xwm tsim cov dej xau los yog ua tsis tiav thaum lub sijhawm, muab cov kev daws teeb meem ntau dua thiab siv tau ntev rau kev tsim kho lub pas dej.
Txawm li cas los xij, tseem muaj qee qhov tsis zoo ntawm PVC geomembrane los xav txog. Piv txwv li, nws tsis hloov pauv raws li qee yam ntawm lwm hom geomembranes, txhais tau tias nws yuav tsis zoo rau cov ntawv thov uas xav tau qib siab ntawm kev yoog raws lossis kev ncab. Tsis tas li ntawd, PVC geomembrane feem ntau kim dua lwm hom geomembranes, uas tej zaum yuav muaj kev txhawj xeeb rau qee qhov kev tsim kho.
HDPE Geomembrane
HDPE geomembrane, ntawm qhov tod tes, yog tsim los ntawm ib hom yas uas paub txog nws lub zog siab, yoog raws, thiab tshuaj tiv thaiv. Nws yog feem ntau siv hauv kev tsim kho av thiab lwm yam kev siv ib puag ncig, qhov uas nws yuav tsum tiv taus ntau yam tshuaj hnyav thiab cov kab mob.
Ib qho ntawm qhov zoo tshaj plaws ntawm HDPE geomembrane yog nws qhov yooj yim. Nws tuaj yeem ua tau yooj yim molded thiab zoo li tus kom haum rau txhua qhov contour lossis txoj kab nqes, ua rau nws muaj ntau yam khoom siv rau kev tsim kho dej. Tsis tas li ntawd, nws feem ntau tsis tshua kim dua li PVC geomembrane, ua rau nws muaj txiaj ntsig zoo rau qee qhov haujlwm.
Lwm qhov zoo dua ntawm HDPE geomembrane yog tias nws muaj kev tiv thaiv siab rau punctures thiab kua muag, txhais tau tias nws tsis zoo li tsim cov dej ntws los yog ua tsis tau raws sijhawm. Qhov no ua rau nws muaj kev ntseeg siab thiab kav ntev rau kev tsim kho lub pas dej.
Txawm li cas los xij, muaj qee qhov tsis zoo ntawm HDPE geomembrane los xav txog ib yam. Piv txwv li, nws tsis yog resistant rau UV rays li PVC geomembrane, txhais tau tias nws yuav degrade lub sij hawm yog tias raug tshav ntuj. Tsis tas li ntawd, HDPE geomembrane yog qhov nyuaj rau vuam ntau dua li PVC geomembrane, txhais tau hais tias nws yuav siv sij hawm ntev dua thiab xav tau cov cuab yeej tshwj xeeb los txhim kho.
Xaus
Hauv kev xaus, ob qho tib si PVC thiab HDPE geomembranes tuaj yeem yog cov kev xaiv zoo rau kev tsim kho lub pas dej, nyob ntawm seb cov kev xav tau tshwj xeeb thiab cov kev xav tau ntawm qhov project. PVC geomembrane feem ntau yooj yim rau nruab thiab tsis tshua muaj kev sib tsoo thiab kua muag, thaum HDPE geomembrane yog hloov tau yooj yim thiab siv tau. Thaum kawg, kev xaiv ntawm PVC thiab HDPE geomembrane yuav nyob ntawm seb qhov loj thiab qhov dav ntawm lub reservoir, qib ntawm lub hnub raug, thiab cov peev nyiaj rau qhov project.
