Hauv peb lub neej niaj hnub, khob ntawv tau dhau los ua ib yam khoom siv.Txawm hais tias nws yog lub khw kas fes, lub tsev tshuaj yej lossis tsev neeg sib sau ua ke, peb txhua tus siv khob ntawv.Txawm li cas los xij, koj puas tau xav tias yog vim li cas cov khob ntawv no tau lees tias tsis xau?Tag nrho cov no yog vim lub khob ntawv tseem ceeb - PE coated ntawv.
PE coated ntawv yobyog cov ntawv ua tiav cov khoom siv nrog ib txheej ntawm polyethylene zaj duab xis rau ntawm daim ntawv.Lub luag haujlwm ntawm txheej txheej ntawm zaj duab xis no yog txhawm rau txhim kho cov dej tsis zoo ntawm lub khob ntawv, thiab tseem txhim kho cov cua sov thiab lub zog ntawm lub khob ntawv.Yog li, PE coated ntawv yuav ua li cas kom ntseeg tau tias lub khob ntawv tsis xau?
Ua ntej tshaj plaws, kev xaiv cov khoom ntawm PE coated ntawv yog qhov tseem ceeb heev rau nws cov dej tsis zoo.Polyethylene zaj duab xis yog cov khoom siv hluavtaws uas muaj qhov hnyav molecular, uas muaj cov dej tsis zoo thiab tuaj yeem tiv thaiv kom tsis txhob ya raws los ntawm kev nkag mus rau sab hauv ntawm lub khob ntawv.Nyob rau tib lub sijhawm, PE coated daim ntawv kuj tau tshwj xeeb kho kom muaj kev sib xyaw ua ke ntawm cov yeeb yaj kiab thiab cov ntawv kom nruj, yog li tsis txhob nkag mus rau hauv dej.
Thib ob, cov txheej txheem ua haujlwm ntawm PE coated ntawv kuj ua lub luag haujlwm tseem ceeb hauv nws cov dej tsis zoo.Thaum lub sij hawm tsim cov txheej txheem, lub tshuab laminating tusyees txau cov molten polyethylene zaj duab xis rau ntawm daim ntawv los ntawm high-pressure cua.Txoj kev ua no tsim ib qho kev sib raug zoo ntawm zaj duab xis thiab daim ntawv, yog li ua kom cov dej tsis zoo ntawm daim ntawv khob.
Thaum kawg, txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm yog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau yog cov ntawv yuav tsum muaj cov ntawv khob kom tsis txhob muaj dej, kev tshuaj xyuas nruj thiab kev tswj xyuas yuav tsum tau ua thaum ua cov ntawv khob kiv cua.Piv txwv li, cov npoo ntawm cov ntawv khob yuav tsum tau txiav kom meej thiab hauv av kom muaj kev sib khi zoo.Nyob rau tib lub sijhawm, qhov zoo ntawm cov ntawv khob yuav tsum tau muab tshuaj ntsuam xyuas thaum lub sijhawm tsim khoom kom ntseeg tau tias lawv ua tau raws li cov qauv zoo xws li dej tsis kam, tiv thaiv tshav kub, thiab lub zog.
Los ntawm nws cov khoom siv tshwj xeeb thiab cov txheej txheem txheej txheem, PE coated ntawv tau ua tiav lav qhov dej tsis zoo ntawm lub khob ntawv.Nws cov dej tsis zoo, ua haujlwm ntev, kev nyab xeeb thiab rov ua dua tshiab ua rau PE coated ntawv yog qhov kev xaiv zoo tshaj plaws rau kev siv dav hauv daim ntawv khob.
