HDPE Waterproofing Geomembrane

Cov geomembrane siv cov yas ua yeeb yaj kiab ua cov yeeb yaj kiab los tiv thaiv nplooj ntawv, cov khoom siv geotextile sib txuas nrog cov ntaub tsis-ntaub, thiab cov yeeb yaj kiab tiv thaiv kev tawm tsam ntawm cov khoom siv tshiab geomembrane feem ntau yog nyob ntawm qhov kev tawm tsam los tiv thaiv kev pom ntawm cov yeeb yaj kiab yas. Yas zaj duab xis rau cov ntawv thov los tiv thaiv kev lag luam hauv tsev thiab txawv teb chaws, feem ntau suav nrog polyvinyl chloride (PVC) thiab polyethylene (PE), EVA (ethylene / vinyl acetate copolymer), thiab siv ECB (ethylene vinyl acetate hloov asphalt) hauv cov ntawv thov. Sib xyaw geomembrane), lawv yog hom ntawm cov khoom siv tshuaj polymer hloov tau nrog kev sib tsoo me me, muaj zog elongation, siab yoog mus ua kom deformation, tiv thaiv corrosion, tsis tshua muaj kub tsis kam thiab ua haujlwm zoo frost.

HDPE waterproofing geomembrane 1

Cov yam ntxwv

Geomembrane yog cov khoom siv dej tsis ua dej tsis haum yog ua raws li cov khoom siv tshaj molecular phaus.

Feem ntau muab faib ua: qis ntom polyethylene (LDPE) geomembrane, high ntom polyethylene (HDPE) geomembrane thiab EVA geomembrane.

1. Qhov dav thiab tuab tiav.

2. nws muaj qhov kev nyuaj siab ib puag ncig tawg zoo heev thiab zoo heev tshuaj lom neeg kuj.

3. Cov tshuaj lom neeg zoo heev.

4. Muaj kev ua haujlwm loj kub thiab muaj kev pabcuam lub neej ntev.

5. Siv rau hauv cov chaw ntim av, cov chaw ntim khoom khaws cia, channel saib kev tiv thaiv kab mob, kev tiv thaiv kom pom lub pas dej tauv thiab lub nkoj hauv av, thiab lwm yam.

Lub tshuab tseem ceeb yog txhawm rau thaiv cov dej hauv qhov dej ntawm lub ntiaj teb los ntawm kev puas tsuaj los ntawm cov yeeb yaj kiab yas, tiv thaiv cov dej siab thiab hloov kho kom lub cev tsis muaj zog ntawm lub pas dej tauv nrog nws lub zog loj thiab lub zog ntev; thiab cov-ntaub npuag kuj tseem yog polymer ua kom luv fiber ntau. Cov khoom siv muaj lub zog tensile siab thiab elongation los ntawm rab koob xuas nrig ntaus los yog kub tack taus. Thaum ua ke nrog cov yas zaj duab xis, nws tsis tsuas yog nce lub zog tensile thiab lub zog tiv thaiv ntawm cov yas zaj duab xis, tab sis kuj ua rau qhov chaw ntxhib ntawm cov ntaub-cov ntaub npuag. Kev sib txhuam coefficient ntawm qhov sib tiv tauj saum npoo tau nce, uas yog txiaj ntsig zoo rau kev ruaj ntseg ntawm kev sib xyaw geomembrane thiab txheej txheej tiv thaiv. Nyob rau tib lub sijhawm, lawv muaj kev xeb zoo tiv thaiv cov kab mob thiab tshuaj lom neeg, thiab tsis ntshai los ntawm cov kua qaub, alkali thiab ntsev yaig. Lawv muaj lub neej ua haujlwm ntev nyob rau hauv cov ntaub ntawv ntawm kev zam lub teeb.
