Lub HDPE geomembrane du yog qhov tsis tshua muaj permeability hluavtaws membrane liner lossis thaiv nrog du nto. Nws tuaj yeem siv nkaus xwb lossis nrog cov khoom siv geotechnical engineering ntsig txog txhawm rau tswj cov dej (lossis roj) kev tsiv teb tsaws hauv tib neeg tsim qhov project, qauv, lossis qhov system. Kev tsim ntawm HDPE geomembrane du pib nrog cov khoom siv raw, uas feem ntau suav nrog HDPE polymer resin, thiab ntau yam khoom ntxiv xws li carbon dub, antioxidants, anti-aging agent, UV absorber, thiab lwm yam adjuvant. HDPE resin thiab additives piv yog 97.5: 2.5.
