Environmental Geomembrane

Environmental geomembrane yog ib hom ntawm HDPE geomembrane, uas yog ua los ntawm opaque thiab translucent thermoplastic khoom siv – polyethylene cob. Kev zoo ntawm thaj chaw geomembrane (HDPE geomembrane) yog lub siab tawv molecular polymer, uas yog ib qho tsis toxic, ntxhiab tsw thiab ntxhiab dawb dawb. Nws qhov taw qhia txog melting yog li 110-130 ℃, thiab nws cov txheeb ze tus txheeb ze yog 0.918-0.965. Qhov nruab nrab geomembrane uas tsim los ntawm cov chaw nruab deg geomembrane (HDPE geomembrane) muaj cua kub zoo thiab txias tsis kam. Nws muaj kev ruaj ntseg tshuaj zoo, muaj rigidity, thiab toughness, zoo mechanical zog, zoo ua hauj lwm rau kev puag ncig kev ntxhov siab thiab qhov muag tawm lub zog. Nrog rau kev nce ceev, kev sib txeeb thiab cov cuab yeej sib zog yuav pom zoo, qhov kub thiab lub zog tensile yuav siab dua; nws tuaj yeem tiv taus acid, alkali, organic solvents thiab lwm yam corrosion.
