Thaum nws los txog rau cov yeeb yaj kiab yas, LDPE (tsawg ntom polyethylene) thiabHDPE (siab ceev polyethylene)yog ob qho khoom siv feem ntau.Ob leeg tau siv dav hauv ntau yam kev lag luam, suav nrog kev ntim khoom, kev ua liaj ua teb, kev tsim kho, thiab lwm yam.To taub qhov sib txawv ntawmLDPE zaj duab xisthiab HDPE zaj duab xis yog qhov tseem ceeb rau kev xaiv cov khoom raug rau ib daim ntawv thov tshwj xeeb.
Ob leeg LDPE thiab HDPE zaj duab xis yog tsim los ntawm ntau lub tuam txhab thoob ntiaj teb.HDPE zaj duab xis manufacturersthiabLDPE zaj duab xis manufacturerstsim cov ntaub ntawv no rau ntau hom ntawv, suav nrog yob, ntawv, thiab hnab, kom tau raws li kev xav tau ntawm cov neeg siv khoom.
Ib qho ntawm qhov sib txawv tseem ceeb ntawm LDPE thiabHDPE zaj duab xisyog lawv cov qauv molecular thiab ntom.HDPE paub txog nws qhov siab siab, uas ua rau nws nyuaj dua thiab ruaj khov dua ldpe.LDPE, ntawm qhov tod tes, muaj qhov ntom ntom, ua rau cov khoom siv tau yooj yim dua.
Hais txog kev siv, HDPE zaj duab xis feem ntau yog siv rau hauv cov khoom ntim hnyav xws li cov ntaub pua tsev, cov ntaub pua tsev, thiab cov ntaub pua tsev.Nws lub zog tensile siab thiab puncture kuj ua rau nws haum rau qhov chaw hnyav.Ntxiv thiab,HDPE zaj duab xisfeem ntau yog siv rau hauv geomembrane daim ntawv thov rau ib puag ncig thiab tiv thaiv.
Hloov chaw, LDPE cov yeeb yaj kiab tau pom zoo rau lawv qhov yooj yim thiab meej, ua rau lawv zoo tagnrho rau kev siv xws li ntim khoom noj, ntim qhwv thiab hnab ntim khoom siv dav dav.Nws muaj peev xwm ua tau raws li cov duab ntawm nws cov ntsiab lus thiab muab cov dej noo zoo heev ua rau nws muaj kev xaiv nrov rau ntau yam kev xav tau ntim.
Lwm qhov sib txawv loj ntawm LDPE thiabHDPE zaj duab xisyog lawv qhov kub tsis kam.HDPE muaj cov ntsiab lus melting ntau dua li LDPE, cia nws tiv taus qhov kub thiab txias.Cov cuab yeej no ua rau cov yeeb yaj kiab HDPE haum rau cov ntawv thov uas xav tau kev sib khi los yog raug rau qhov kub thiab txias.
Ntxiv thiab,LDPE thiab HDPE zaj duab xismuaj kev cuam tshuam ib puag ncig sib txawv vim lawv qhov ntom ntom thiab rov ua dua tshiab.Thaum ob qho khoom siv rov ua dua tshiab, HDPE feem ntau suav tias yog ib puag ncig zoo dua vim nws qhov ntom ntom dua, uas ua rau siv cov khoom siv tsawg dua thiab pov tseg tsawg dua.NtauHDPE zaj duab xis manufacturersyog qhov tseem ceeb ntawm kev ruaj ntseg los ntawm kev muab cov kev xaiv rov ua dua tshiab thiab eco-phooj ywg kom tau raws li qhov xav tau loj zuj zus ntxiv rau kev daws teeb meem kev ntim khoom ib puag ncig.
Hauv kev xaus, thaum ob qho tib si LDPE thiabHDPE zaj duab xisyog cov khoom siv ntau yam nrog ntau yam kev siv, kev nkag siab txog lawv qhov sib txawv yog qhov tseem ceeb rau kev xaiv cov khoom siv rau koj cov kev xav tau tshwj xeeb.Txawm hais tias nws yog qhov nruj thiab lub zog ntawm HDPE los yog qhov yooj yim thiab pob tshab ntawm LDPE, txhua yam khoom muaj cov khoom tshwj xeeb uas tuaj yeem ua tau raws li qhov xav tau sib txawv.Los ntawm kev koom tes nrog lub koob npe nrovLDPE zaj duab xisthiab HDPE zaj duab xis chaw tsim tshuaj paus, tuam txhab uas muag tuaj yeem tau txais cov ntaub ntawv zoo tsim nyog rau lawv cov kev siv tshwj xeeb, thaum kawg pab txhawb kev ua haujlwm zoo thiab ua tiav.
