Grouted masonry, pob zeb, lossis zaj duab xis tuaj yeem siv los tiv thaiv kwj dej.Kangping County nyob rau hauv ib cheeb tsam txias heev, nrog rau qhov sib sib zog nqus khov thiab loj te heaves.Yog hais tias ib tug nruj anti-seepage qauv yog saws, ib tug loj tus naj npawb ntawm hloov khaubncaws sab nraud povtseg yuav tsum tau, thiab qhov project peev yog siab.Qhov sib xyaw geomembrane muaj cov yam ntxwv ntawm lub zog siab, zoo extensibility, loj deformation modulus, acid thiab alkali tsis kam, corrosion kuj, laus kuj, thiab zoo impermeability.Nws tuaj yeem siv rau hauv qhov chaw kub tsis sib xws vim nws siv cov khoom siv polymer thiab cov tshuaj tiv thaiv kev laus ntxiv thaum lub sijhawm tsim khoom.Nws feem ntau yog siv rau kev tiv thaiv kev kho mob ntawm cov kwj dej thiab cov kwj dej.Composite geomembrane muaj qhov zoo hauv qab no.
1.High impermeability coefficient: Cov khoom sib xyaw LDPE geomembrane rau kev muag khoom muaj qhov tsis sib xws ntawm impermeability nyhuv, siab zog, thiab tensile lub zog, thiab nws zoo heev elasticity thiab deformability ua rau nws zoo heev rau expanding los yog shrinking lub hauv paus nto.
2.Chemical stability: Cov khoom sib xyaw geomembrane muaj cov tshuaj lom neeg ruaj khov thiab siv dav hauv kev kho dej phwj, cov tshuaj tiv thaiv tank, thiab cov chaw pov tseg.
3.Los tiv thaiv kev laus: Cov khoom sib xyaw geomembrane muaj kev tiv thaiv kev laus, tiv thaiv ultraviolet, cov yam ntxwv tiv thaiv decomposition, thiab tuaj yeem siv rau hauv qhov liab qab installation.Cov khoom siv muaj kev pab cuam lub neej ntawm 50 mus rau 70 xyoo, muab cov khoom zoo rau kev tiv thaiv ib puag ncig seepage, thiab ua kom muaj zog tiv thaiv cov hauv paus hniav.
4.Lub zog txhua yam: Cov khoom sib xyaw geomembrane muaj lub zog zoo txhua yam, lub zog tensile ntawm kev tawg yog 28MP, thiab elongation ntawm kev tawg yog 700%.
5.Tus nqi qis thiab kev ua haujlwm siab: Cov khoom sib xyaw geomembrane txais cov thev naus laus zis tshiab los txhim kho cov nyhuv anti-seepage, tab sis cov txheej txheem ntau lawm yog kev tshawb fawb thiab nrawm dua, thiab cov nqi khoom qis dua li cov khoom siv dej tsis zoo.Raws li qhov tseeb suav, kev siv cov khoom sib xyaw geomembrane tsim los ntawm cov chaw tsim khoom hauv av geomembrane hauv cov haujlwm dav dav yuav txuag tau li 50% ntawm tus nqi.
6.Kev tsim kho ceev ceev: Cov khoom sib xyaw geomembrane muaj qhov hloov tau yooj yim, ntau yam kev qhia tshwj xeeb, thiab ntau cov ntaub ntawv tso, uas tuaj yeem ua tau raws li qhov yuav tsum tau ua los tiv thaiv cov dej ntws ntawm cov haujlwm sib txawv.Kub-melt welding yog saws, nrog siab vuam lub zog thiab yooj yim thiab ceev kev tsim kho.
7.Kev tiv thaiv ib puag ncig thiab tsis muaj tshuaj lom: Tag nrho cov ntaub ntawv siv hauv cov khoom sib xyaw geomembrane yog cov khoom tsis muaj tshuaj lom thiab ib puag ncig.Lub hauv paus ntsiab lus los tiv thaiv cov dej ntws yog ib qho kev hloov pauv ntawm lub cev thiab tsis tsim cov tshuaj phem, yog li nws yog qhov kev xaiv zoo tshaj plaws rau kev tiv thaiv ib puag ncig, kev cog qoob loo, thiab cov pas dej haus.
Nyob rau tib lub sijhawm, piv nrog cov ntaub ntawv xws li mortar masonry thiab pob zeb, tus nqi qis textured geomembrane zoo heev txo nqi engineering.Yog li ntawd, ib qho kev sib xyaw geomembrane raug xaiv rau kev tswj xyuas qhov project no.
