High-density polyethylene (HDPE) geomembranes rau landfills

Lus piav qhia luv luv:

HDPE geomembrane liner yog tshuab moulded los ntawm cov khoom siv polyethylene polymer. Nws lub luag haujlwm tseem ceeb yog los tiv thaiv cov kua xau thiab roj evaporation. Raws li cov khoom siv raw, nws tuaj yeem muab faib ua HDPE geomembrane liner thiab EVA geomembrane liner.

Product Detail

Khoom Description

HDPE geomembrane yog ib qho ntawm cov khoom siv geosynthetic, nws muaj qhov zoo ntawm ib puag ncig kev ntxhov siab tawg tsis kam, tsis kub tsis kam, tiv thaiv kev laus, kev tiv thaiv corrosion, nrog rau qhov kub thiab txias ntau thiab kev pab lub neej ntev, dav siv hauv cov khoom pov tseg hauv tsev, cov khoom pov tseg. pov tseg impermeability, dej phwj kho nroj tsuag impermeability, dag lake impermeability, tailings kho thiab lwm yam impermeability tej yaam num.

Cov yam ntxwv ua haujlwm

1. Tsis muaj tshuaj ntxiv, tsis dhau kev kho cua sov, yog ib qho khoom siv hauv tsev.
2. Muaj cov khoom siv zoo, cov dej zoo permeability, thiab tuaj yeem tiv taus corrosion, tiv thaiv kev laus.
3. Nrog muaj zog faus tsis kam, corrosion kuj, fluffy qauv, nrog rau kev ua haujlwm zoo.
4. Muaj coefficient zoo ntawm kev sib txhuam thiab tensile lub zog, nrog geotechnical reinforcement kev ua tau zoo.
5. Nrog kev sib cais, pom, dej ntws, kev tiv thaiv, ruaj khov, ntxiv dag zog thiab lwm yam haujlwm.
6. tuaj yeem hloov mus rau lub hauv paus tsis sib xws, tuaj yeem tiv thaiv kev puas tsuaj ntawm kev tsim kho sab nraud, creep ua me.
7. Lub zuag qhia tag nrho txuas ntxiv yog qhov zoo, lub teeb yuag, kev tsim kho yooj yim.
8. Nws yog cov khoom siv permeable, yog li nws muaj kev pom zoo cais tawm, muaj zog puncture tsis kam, yog li nws muaj kev tiv thaiv zoo.
