HDPE zaj duab xis: Tshawb Nrhiav Nws Cov Khoom
High-density polyethylene (HDPE) yog ib qho nrov thermoplastic polymer siv nyob rau hauv ntau yam kev lag luam.Ib qho ntawm cov ntawv thov tseem ceeb ntawm HDPE yog hauv kev tsim cov yeeb yaj kiab.HDPE zaj duab xis, tseem hu ua high-density polyethylene zaj duab xis, yog cov khoom siv ntau yam nrog ntau yam khoom thiab cov txiaj ntsig.
Ib qho ntawm cov khoom tseem ceeb ntawm HDPE zaj duab xis yog nws cov khoom thaiv zoo heev.Nws muaj cov dej noo zoo heev, roj thiab tshuaj tiv thaiv, ua rau nws zoo tagnrho rau cov ntawv ntim khoom.HDPE films ua raws li kev txhim khu kev qha tiv thaiv kev hloov pauv ntawm cov dej noo thiab cov pa roj, pab tswj cov khoom zoo thiab tshiab ntawm cov khoom ntim.Qhov no ua rau nws yog ib qho kev xaiv zoo tshaj plaws rau kev ntim khoom noj, qhov uas tswj kev ncaj ncees ntawm cov ntsiab lus tseem ceeb heev.
Lwm yam khoom tseem ceeb ntawmHDPE zaj duab xisyog nws lub zog tensile siab.HDPE zaj duab xis muaj cov qauv molecular muaj zog uas muab nws lub zog tshwj xeeb thiab ua haujlwm ntev.Lawv tuaj yeem tiv taus txhua yam kev ntxhov siab thiab muaj kua muag zoo heev thiab puncture tsis kam.Cov cuab yeej no ua rau HDPE cov yeeb yaj kiab tsim nyog rau cov ntawv thov hnyav xws li kev ntim khoom, kev tsim cov yeeb yaj kiab thiab kev ua liaj ua teb mulches.
HDPE films kuj pom zoo UV tiv thaiv.Nws yog heev resistant rau fading thiab degradation tshwm sim los ntawm raug rau lub hnub lub ultraviolet hluav taws xob.Cov cuab yeej no yog qhov tseem ceeb hauv kev siv sab nraum zoov xws li cov yeeb yaj kiab ua liaj ua teb thiab tsev cog khoom npog, vim nws ua kom lub neej ntev thiab ua haujlwm ntev ntawm cov yeeb yaj kiab txawm tias raug tshav ntuj muaj zog rau lub sijhawm ntev.
Tsis tas li ntawd, HDPE cov yeeb yaj kiab tau paub txog lawv qhov yooj yim.Nws muaj cov coefficient tsawg ntawm kev sib txhuam, ua rau nws yooj yim rau tshuab thiab hloov mus rau hauv cov duab sib txawv thiab ntau thiab tsawg.HDPE zaj duab xis tuaj yeem tsim ntau yam tuab, los ntawm cov yeeb yaj kiab nyias heev rau kev ntim cov ntawv thov rau cov yeeb yaj kiab tuab rau kev siv ntau dua.Qhov yooj thiab ntau yam ntawm HDPE films ua rau lawv haum rau ntau yam ntim, qhwv thiab tiv thaiv daim ntaub ntawv.
Ntxiv thiab,HDPE zaj duab xisyog chemically inert, txhais tau tias nws yuav tsis hnov mob nrog ntau yam tshuaj.Cov cuab yeej no ua rau nws tiv taus corrosion thiab degradation los ntawm kev raug tshuaj lom neeg, roj thiab cov kuab tshuaj.Raws li qhov tshwm sim, HDPE cov yeeb yaj kiab tswj hwm lawv txoj kev ncaj ncees thiab kev ua haujlwm txawm tias nyob rau hauv ib puag ncig tshuaj lom neeg.Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv hauv kev lag luam xws li tshuaj lom neeg lub nruas hauv ob sab phlu, nrog rau cov khoom ntim khoom uas muaj cov khoom corrosive.
Hauv cov ntsiab lus,HDPE zaj duab xismuaj ntau yam khoom muaj txiaj ntsig uas ua rau lawv zoo tagnrho rau ntau yam kev siv.Nws cov khoom thaiv zoo heev, siab tensile zog, UV tsis kam, yoog raws thiab tshuaj inertness ua rau nws muaj ntau yam khoom siv rau kev ntim khoom, kev tiv thaiv thiab kev lag luam.Nws muaj peev xwm tswj tau qhov zoo thiab qhov tshiab ntawm cov ntsiab lus, tiv taus cov neeg kho tshuab kev ntxhov siab thiab tiv thaiv fading thiab degradation ua rau nws muaj kev ntseeg siab nyob rau hauv kev lag luam.Nrog nws cov khoom siv dav dav, HDPE cov yeeb yaj kiab tseem yog thawj qhov kev xaiv rau ntau lub tuam txhab nrhiav cov khoom siv ruaj khov, ntau yam thiab raug nqi kom tau raws li lawv cov kev ntim khoom thiab kev tiv thaiv.
