Khoom Description
Vim li cas thiaj xaiv PE geomembrane pas dej liner daim ntawv rau cov pas dej ntses thiab dab tsi yuav tsum tau sau tseg thaum lub sijhawm teeb tsa?
Cov pas dej ntses yog ib feem tseem ceeb ntawm kev lag luam aquaculture. Tus yuam sij rau kev ua liaj ua teb ua liaj ua teb tau zoo yog qhov chaw noj qab haus huv thiab ruaj khov rau cov ntses kom loj hlob. Ntawm cov ntaub ntawv muaj, polyethylene (PE) geomembranes yog qhov kev xaiv nrov rau cov pas dej ntses vim lawv cov dej tsis zoo, ua haujlwm ntev, thiab yooj yim ntawm kev teeb tsa.
Polyethylene ntses pas dej lineryog tsim los ntawm high-density polyethylene (HDPE), uas yog cov khoom siv thermoplastic uas tiv taus ib puag ncig xws li dej, cua sov, thiab UV teeb. Lawv kuj muaj zoo mechanical zog, uas ua rau lawv resistant rau punctures thiab abrasions. Cov yam ntxwv no ua rau lawv zoo tagnrho rau hauv cov pas dej ntses, vim tias lawv tuaj yeem tiv thaiv cov dej ntws thiab txo qhov kev pheej hmoo ntawm kev kis kab mob los ntawm cov av ib puag ncig thiab lwm yam pa phem.
Cov khoom siv
Thaum nruabhdpe geoliner sivHauv cov pas dej ntses, muaj ob peb yam tseem ceeb uas yuav tsum tau xav txog. Ua ntej thiab qhov tseem ceeb tshaj plaws, nws yog ib qho tseem ceeb kom paub meej tias lub txaj hauv pas dej tau npaj kom zoo. Qhov no suav nrog tshem tawm cov khib nyiab lossis cov khoom ntse uas tuaj yeem tsoo lub geomembrane. Lub txaj yuav tsum tau compacted thiab leveled los tsim ib tug du nto rau liner.
Lwm qhov kev txiav txim siab tseem ceeb yog qhov zoo ntawm lub installation. Aquaculture ntses pas dej liner hdpe geomembrane yuav tsum tau muab tso rau hauv ib txoj hauv kev uas txo qis wrinkles thiab folds, vim tias cov no tuaj yeem tsim cov chaw tsis muaj zog uas tuaj yeem ua rau xau dhau sijhawm. Nws tseem yog ib qho tseem ceeb los xyuas kom meej tias cov liner tau raug khi rau hauv cov phab ntsa hauv pas dej kom tsis txhob muaj kev txav los yog kev puas tsuaj vim cua los yog dej ntws.
Thaum kawg, nws yog ib qho tseem ceeb uas yuav tau soj ntsuam lub liner ib ntus kom paub tseeb tias nws ua haujlwm zoo. Qhov no tuaj yeem suav nrog kev kuaj xyuas cov dej xau, saib xyuas cov qib dej, thiab xyuas kom meej tias cov ntaub ntawv tsis raug puas los ntawm cov khib nyiab lossis cov tsiaj qus.
Khoom Advantage
Hauv kev xaus,tushdpe geomembrane muajyog ib qho kev xaiv nrov rau hauv cov pas dej ntses vim lawv cov dej tsis zoo, ua haujlwm ntev, thiab yooj yim ntawm kev teeb tsa. Txawm li cas los xij, kev npaj thiab kev teeb tsa kom raug yog qhov tseem ceeb los ua kom muaj kev noj qab haus huv thiab nyob ruaj khov rau kev ua liaj ua teb ntses. Los ntawm kev ua raws li cov kauj ruam thiab kev saib xyuas kom raug, nws muaj peev xwm tsim tau ib lub pas dej ntses uas muaj kev vam meej uas txhawb nqa ob qho tib si ib puag ncig thiab kev lag luam aquaculture.
