HDPE Smooth Geomembrane|High -Lub zog tiv thaiv kab mob
HDPE du geomembrane yog ib qho khoom siv hauv ob sab phlu uas ua haujlwm tsis tu ncua rau kev kaw cov kua dej, cais cov av hauv av, thiab tswj kev nkag mus rau hauv kev tsim vaj tsev hauv vaj tse.
Material Structure thiab Functional Principple
Lub geomembrane yog tsim los ntawm extrusion ntawm nkauj xwb HDPE resin, tsim ib tug ntom polymer matrix uas hloov tensile kev nyuaj siab nyob rau hauv daim ntawv thiab tswj qhov seem stability nyob rau hauv mechanical load.
Cov pa roj carbon dub yog dispersed nyob rau hauv polymer los thaiv UV hluav taws xob thiab qeeb molecular saw degradation thaum raug sab nraum zoov.
Daim ntawv thov Scenario
Landfill Base Liner
Blocks leachate nkag mus thiab cais cov khib nyiab los ntawm cov dej hauv av.
Mining Heap Leach Pad
Resistant acidic tov raug thiab txhawb ore stacking load faib.
Dej Reservoir
Seals av nto thiab tiv thaiv seepage poob nyob rau hauv cia basins.
Lub pas dej Aquaculture
Tswj dej pauv thiab tswj cov pas dej hydraulic ruaj khov.
Installation Workflow (Engineering Execution Process)
Cov txheej txheem kev teeb tsa tau ua tiav hauv cov txheej txheem engineering tswj kom ntseeg tau tias geomembrane tuaj yeem kaw thiab tswj kev ncaj ncees raws li hydraulic load, av txav, thiab ntev - raug.
1. Subgrade Preparation thiab Compaction
Cov av saum npoo yog graded thiab compacted los tswj kev sib haum xeeb. Cov khoom ntse raug tshem tawm kom tsis txhob muaj kev ntxhov siab rau ntawm daim nyias nyias.
Lub hom phiaj kev sib cog lus feem ntau yog tswj tau ntau dua lossis sib npaug li 90-95% Proctor ntom nyob ntawm qhov project tsim.
2. Geotextile Separation Txheej Txheej
Nonwoven geotextile yog ntsia los faib kev sib cuag siab thiab cais HDPE geomembrane los ntawm subgrade puas.
Feem ntau qhov hnyav: 200-800 g / m² nyob ntawm lub hauv paus roughness.
3. Geomembrane Deployment thiab Alignment
Rolls raug xa mus raws txoj kev nqes hav kom txo tau cov tensile kev nyuaj siab tsub zuj zuj. Panels yog positioned nrog tswj sib tshooj (100-150 mm).
Expansion nyiaj tso cai rau kom haum raws li thermal elongation nyob rau hauv qhov chaw kub variation.
4. Thermal Vuam ntawm Seams
Kub wedge los yog cua kub welding yog siv rau fuse polymer chains hla ib cheeb tsam sib tshooj thiab tsim kev sib txuas txuas txuas ntxiv.
Vuam tsis tau (kub, ceev, siab) yog kho raws li ambient tej yam kev mob thiab cov khoom thickness.
5. Tsis yog-Kev kuaj kev puas tsuaj
Kev ntsuam xyuas huab cua los yog lub tshuab nqus tsev ntsuas yog ua raws cov welded seams kom paub tseeb tias qhov tsis tuaj yeem thiab kev sib txuas txuas ntxiv.
Kev ntsuas siab yog tswj raws li ASTM lossis qhov project specification.
6. Npog lossis Kev Pabcuam Sau
Tom qab kuaj xyuas, daim nyias nyias yog them nrog cov txheej tiv thaiv av los yog ntim nrog dej / khib nyiab nyob ntawm daim ntawv thov.
Load faib yog saib xyuas kom tsis txhob muaj kev ntxhov siab hauv zos deformation.

Engineering Case Study
Chile Mining Heap Leach Pad Project
HDPE du geomembrane tau teeb tsa ua lub hauv paus liner los muab cov tshuaj cyanide ntim rau hauv cov tooj liab mining heap leach system. Lub membrane raug xaiv rau cov tshuaj tiv thaiv thiab kev thauj mus los hauv qab ore stacking.
Specification: 1.5 hli HDPE. Muaj nuj nqi: chemical containment thiab seepage control. Thaj Chaw: 180,000 m².
Xa peb cov ntaub ntawv koj qhov project (daim ntawv thov, tuab, thiab cheeb tsam) kom tau txais cov kev daws teeb meem HDPE geomembrane thiab hais lus hauv 24 teev.
