Polyethylene hmoov txheej yog tsim los ntawm tib yam khoom raws li polyethylene yas, thiab nws yog feem ntau muaj kev nyab xeeb siv.
Txawm li cas los xij, muaj qee yam uas tuaj yeem cuam tshuam kev nyab xeeb ntawm polyethylene hmoov txheej. Ib qho ntawm cov xwm txheej no yog qhov muaj cov khoom ntxiv thiab cov xim uas siv los hloov cov khoom ntawm txheej txheej. Qee cov additives thiab pigments no tej zaum yuav muaj tshuaj lom los yog ua rau tib neeg noj qab haus huv thiab ib puag ncig, tshwj xeeb tshaj yog tias lawv tsis muab pov tseg kom zoo.
Lwm yam uas tuaj yeem cuam tshuam rau kev nyab xeeb ntawm polyethylene hmoov txheej yog txoj kev siv. Hmoov txheej feem ntau yog siv los ntawm rab phom los yog fluidized txaj, uas tuaj yeem tsim cov huab cua zoo ntawm cov khoom uas tuaj yeem nqus tau. Yog tias cov hmoov txheej muaj cov tshuaj lom neeg ntxiv lossis cov pigments, kev nqus ntawm cov khoom no tuaj yeem ua rau muaj kev pheej hmoo rau tib neeg kev noj qab haus huv.
Txhawm rau kom muaj kev nyab xeeb ntawm polyethylene hmoov txheej, nws yog ib qho tseem ceeb uas yuav tsum tau siv cov khoom zoo uas tsis muaj tshuaj lom thiab cov pigments. Cov txheej yuav tsum tau siv kom zoo siv cov kev ntsuas kev nyab xeeb uas tsim nyog, xws li hnav khaub ncaws tiv thaiv thiab siv lub tshuab ua pa kom txo tau qhov kev pheej hmoo ntawm kev nqus pa.
Ntxiv rau qhov muaj peev xwm txaus ntshai rau tib neeg kev noj qab haus huv, tseem muaj kev txhawj xeeb txog kev cuam tshuam ib puag ncig ntawm polyethylene hmoov txheej. Polyethylene yog ib yam khoom uas tsis yog biodegradable uas tuaj yeem nyob hauv ib puag ncig rau ntau xyoo. Yog tias cov hmoov txheej tsis muab pov tseg kom zoo, nws tuaj yeem ua rau muaj kuab paug thiab ua rau ib puag ncig.
Txhawm rau txo qhov cuam tshuam ib puag ncig ntawm polyethylene hmoov txheej, nws yog ib qho tseem ceeb uas yuav tsum tau siv cov khoom siv hauv eco uas yog biodegradable lossis recyclable. Cov txheej yuav tsum tau muab pov tseg kom zoo los ntawm kev siv cov kev tswj xyuas pov tseg kom tsim nyog kom txo tau cov pa phem.
Hauv cov ntsiab lus, polyethylene hmoov txheej feem ntau suav tias yog kev nyab xeeb thiab tsis muaj tshuaj lom, tab sis muaj qee yam uas tuaj yeem cuam tshuam rau nws txoj kev nyab xeeb. Lub xub ntiag ntawm cov tshuaj lom additives thiab pigments, nrog rau cov kev siv tsis raug, tuaj yeem ua rau muaj kev pheej hmoo rau tib neeg kev noj qab haus huv thiab ib puag ncig. Txhawm rau kom muaj kev nyab xeeb ntawm polyethylene hmoov txheej, nws yog ib qho tseem ceeb uas yuav tsum tau siv cov khoom zoo thiab kev ntsuas kev nyab xeeb kom raug. Kev cuam tshuam ib puag ncig ntawm polyethylene hmoov txheej kuj tuaj yeem raug txo los ntawm kev siv cov khoom siv hauv eco thiab kev tswj cov khoom pov tseg kom zoo.
