(1) Kev sib koom tes ntawm geomembrane yog cov txheej txheem kev tsim kho tseem ceeb, uas cuam tshuam ncaj qha rau kev pab lub neej ntawm txoj haujlwm. Raws li kev soj ntsuam kev ua tau zoo, kev siv cov khoom siv cua sov yog qhov zoo tagnrho. Cov txheej txheem thermal vuam yog ua kom kub saum npoo ntawm PE geomembrane kom yaj nws, thiab tom qab ntawd ua ke nws nrog kev kub siab.
(2) Lub geomembrane tso rau hauv ib qho kev coj ua, thiab qee yam PE zaj duab xis thiab PET nplaum txheej tau tshwj tseg rau ob tog ntawm geomembrane. Thaum pw, cov kev taw qhia ntawm txhua chav tsev ntawm geomembrane yuav tsum tau tsim kho kom haum rau kev vuam ntawm ob chav geomembrane.
(3) Tom qab tso cov geomembrane, siv cov hnab xuab zeb los txhuam nws kom tiv thaiv cov cua txav, thiab yuav tsum tsis txhob muaj av, ya raws, plua plav thiab lwm yam ntawm cov pob qij txha.
(4) Ua ntej welding, kho lub PE ib txheej zaj duab xis ntawm ob sab ntawm qhov sib koom ua ke kom nws sib tshooj qee qhov dav, thiab tiaj thiab tsis muaj wrinkles.
(5) Thaum vuam, tus kws tshaj lij nrog kev paub tseeb yuav tsum tau siv rau kev vuam, thiab lub tshuab vuam siv tshwj xeeb yuav tsum siv vuam. Nws yog ib qho tsim nyog yuav tau kho qhov kub thiab txias (nws kuj tseem tuaj yeem dhau mus).
Raws li kev xyaum ua ntau xyoo, lub tuab ntawm geomembrane tsis tsawg dua 0.25 hli. Yog tias nws thau tawm nyias, pores tuaj yeem tsim tawm, uas yooj yim puas ntsoog thaum lub sijhawm kev tsim kho thiab txo cov haujlwm los tiv thaiv nplooj ntawv. Hauv kev tsim kho ntawm geomembrane, yuav tsum tau them nyiaj tshwj xeeb kom ntseeg tau tias kev tso kom tsis nruj dhau, tsis muaj qhov qhwv, thiab splicing yuav tsum ruaj. Kev tsim kho yuav tsum tau ua kom nruj raws li cov cuab yeej ntawm cov txheej txheem, thiab tsib qhov kev paub zoo ntawm kev npaj, tso, splicing, tshuaj ntsuam thiab rov qab yuav tsum tau kuaj xyuas.
