Khoom Description
HDPE yog hom yas uas paub txog nws cov tshuaj tiv thaiv zoo heev, lub zog siab, thiab kav ntev. Nws yog dav siv nyob rau hauv geomembrane liners vim nws muaj peev xwm tiv taus ib puag ncig hnyav, nrog rau raug tshuaj lom neeg, UV hluav taws xob, thiab kev ntxhov siab.
Lub geomembrane liner yog textured, txhais tau tias nws muaj tus qauv lossis tus qauv tsim uas muab kev sib txhuam thiab tuav. Cov kev ntxhib los mos pab txhim kho lub liner lub interface nrog cov subgrade los yog lwm yam ntaub ntawv, txo qhov muaj peev xwm rau slippage los yog txav. Lub textured nto kuj ua rau cov liner tiv thaiv punctures thiab txhim kho nws tag nrho stability.
Lub liner muaj ib lub thickness ntawm 1.5 hli, uas qhia tau hais tias cov ntaub ntawv lub zuag qhia tag nrho thickness. Qhov tuab no feem ntau xaiv raws li cov kev xav tau tshwj xeeb ntawm qhov project, xav txog yam xws li durability, tshuaj tiv thaiv, thiab kev cia siab ntawm kev thauj khoom lossis kev ntxhov siab lub liner yuav ntsib.
Geomembrane liners feem ntau yog tsim los ntawm cov yob loj thiab raug teeb tsa los ntawm cov kws tshaj lij. Lawv ua raws li kev thaiv kev tiv thaiv kev tsiv teb tsaws ntawm cov kua, roj, lossis cov khoom paug mus rau hauv lossis tawm ntawm ib cheeb tsam tshwj xeeb, ua kom muaj kev tiv thaiv ib puag ncig thiab tiv thaiv. Qhov kev xaiv ntawm 1.5mm textured HDPE geomembrane liner yuav nyob ntawm seb cov kev xav tau tshwj xeeb ntawm qhov project, nrog rau cov kev xav tau ntawm cov kev ntxhov siab, tshuaj lom neeg, thiab qhov xav tau lifespan ntawm liner.
Daim ntawv thov

1. Landfill Liners: Geomembrane liners feem ntau yog siv rau hauv kev tsim cov khoom pov tseg los tsim kev thaiv ntawm cov khoom pov tseg thiab ib puag ncig ib puag ncig. Kev ntxhib los mos ntawm HDPE liner pab txhim kho kev ruaj ntseg, txo qis, thiab txhim khu lub liner tiv thaiv rau punctures thiab kua muag.
2. Pas dej thiab Reservoir Liners: Geomembrane liners yog siv rau kab pas dej, reservoir, thiab lwm yam dej ntim cov qauv. Kev ntxhib los mos ntawm qhov chaw pab txo qis qis thiab muab lub hauv paus ruaj khov rau liner. Nws tiv thaiv seepage thiab leakage ntawm dej, kom ntseeg tau cov dej zoo thiab khaws cia.
3. Mining Containment: Hauv kev ua haujlwm mining, geomembrane liners yog siv los ua kab tailings pas dej, heap leach pads, thiab lwm yam khoom ntim. Lub liner tiv thaiv kev tso tawm cov tshuaj phem thiab cov kab mob sib kis mus rau ib puag ncig ib puag ncig, tiv thaiv dej hauv av thiab av zoo.
4. Cov nroj tsuag kho cov dej khib nyiab: Geomembrane liners yog siv rau hauv cov chaw kho dej khib nyiab los ua cov kab clarifiers, cov pas dej hauv pas dej, thiab lwm yam khoom ntim. Cov hnab looj tes pab tiv thaiv kom tsis txhob xau thiab kev nkag mus, kom ntseeg tau tias cov dej khib nyiab kho tau zoo thiab tsis muaj kab mob nyob ib puag ncig.
5. Agricultural Applications: Textured HDPE geomembrane liners yog siv rau hauv kev ua liaj ua teb rau cov kwj dej hauv cov kwj dej, cov pas dej, thiab cov pas dej ua liaj ua teb. Lawv pab tiv thaiv cov dej seepage thiab khaws cov dej kom zoo irrigation, txo cov dej poob thiab txhim kho kev tswj dej tag nrho.
6. Cov phiaj xwm tiv thaiv ib puag ncig: Geomembrane liner yog siv rau hauv ntau yam kev tiv thaiv ib puag ncig, xws li pov tseg pov tseg pov tseg, chaw tshawb nrhiav roj thiab roj, thiab kho qhov chaw muaj kab mob. Cov liners ua raws li kev thaiv kev tiv thaiv kev tsiv teb tsaws ntawm cov pa phem, ua kom muaj kev tiv thaiv zoo thiab kev tiv thaiv ib puag ncig.
Technical data
Cov txheej txheem tsim khoom ntawm 1.5mm textured HDPE geomembrane liner muaj ob peb kauj ruam. Ntawm no yog cov ntsiab lus dav dav ntawm cov txheej txheem:
1. Raw Material Preparation: High-Density Polyethylene (HDPE) resin feem ntau yog siv los ua cov khoom siv rau geomembrane liner. Cov resin tau txais hauv daim ntawv pellet thiab tau txais ntau yam kev kuaj xyuas kom ntseeg tau tias nws ua tau raws li qhov yuav tsum tau ua.
2. Extrusion: Cov HDPE resin pellets ces muab tso rau hauv ib qho extruder, uas melts cov resin thiab ua rau nws mus rau hauv ib tug nruam, tiaj daim ntawv. Lub extruder muaj ib tug rhuab chim chim thiab ib tug ntsia hlau uas thawb lub molten resin los ntawm ib tug tuag, shaping nws mus rau hauv lub xav thickness thiab dav.
3. Texturing: Thaum daim ntawv HDPE raug tsim, nws dhau los ntawm chav tsev texturing. Chav tsev no siv tus qauv lossis kev ntxhib los mos rau ib lossis ob sab ntawm daim ntawv. Cov kev ntxhib los mos txhim kho kev sib txhuam thiab tuav, txhim kho lub liner lub interface nrog cov subgrade thiab txo cov feem ntawm slippage.
4. Txias thiab Sizing: Tom qab texturing, daim ntawv mus los ntawm cov txheej txheem txias kom solidify lub molten HDPE thiab stabilize nws qhov ntev. Nws tuaj yeem dhau los ntawm cov txheej txheem txias txias los yog da dej kom ceev cov khoom txias. Thaum lub sijhawm no, lub liner qhov dav thiab tuab kuj tau ua tib zoo saib xyuas thiab kho raws li xav tau.
5. Kev Tswjhwm Zoo: Cov txheej txheem HDPE geomembrane liner yog tom qab ntawd raug kuaj xyuas nruj kom ntseeg tau tias nws ua tau raws li cov qauv xav tau. Cov kev ntsuam xyuas no yuav suav nrog ntsuas qhov tuab, lub zog tensile, tsim kua muag tsis kam, puncture resistance, thiab lwm yam khoom muaj feem xyuam.
6. Rolling thiab ntim: Thaum lub geomembrane liner dhau tag nrho cov kev tswj xyuas zoo, nws yog dov mus rau cov spools loj los yog reels. Lub liner tau ua tib zoo raug mob los tiv thaiv kev puas tsuaj thaum thauj thiab khaws cia. Nws tuaj yeem raug ntim rau hauv cov ntaub qhwv los tiv thaiv nws los ntawm kev raug UV teeb thiab lwm yam kev phom sij.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov txheej txheem tsim khoom tshwj xeeb yuav txawv nyob ntawm cov chaw tsim khoom, cov cuab yeej siv, thiab cov khoom xav tau ntawm geomembrane liner. Cov neeg tsim khoom kuj tseem tuaj yeem suav nrog cov kauj ruam ntxiv, xws li ntxiv UV stabilizers lossis lwm yam khoom siv ntxiv los txhim kho lub liner qhov kev ua tau zoo thiab kev ua haujlwm ntev.
