PE yog dab tsi?

Ua ntej nkag siab txog daim ntawv PE coated, cia peb tham txog nws cov khoom siv tseem ceeb – polyethylene. Polyethylene luv rau PE, uas yog cov thermoplastic resin polymerized los ntawm ethylene. Cov tsos ntawm polyethylene yog cov khoom me me dawb milky waxy, uas tsis muaj saj, tsis muaj ntxhiab, tsis muaj tshuaj lom thiab zoo li quav ciab. Lub ntsiab feature ntawm polyethylene yog pheej yig, uas muaj kev tiv thaiv txias zoo heev, kev ruaj khov tshuaj lom neeg, kev rwb thaiv tsev hluav taws xob thiab lwm yam ntxwv. Yog li nws muaj ntau yam kev siv. Feem ntau siv rau hauv kev tsim cov yeeb yaj kiab, cov ntaub ntawv ntim khoom, cov thawv, cov kav dej, cov xov hlau thiab cov cables, cov khoom siv niaj hnub, thiab lwm yam. Ntxiv mus, nws tuaj yeem siv ua cov ntaub ntawv rwb thaiv tsev siab rau cov TV, radars, thiab lwm yam. Txij li thaum nws daim ntawv thov hauv xyoo 1922, polyethylene tau tsim mus rau hauv lub ntiaj teb cov khoom siv hluavtaws loj tshaj plaws thiab kev siv cov ntaub ntawv ntim khoom yas loj tshaj plaws. Nws nyob hauv txoj haujlwm tseem ceeb hauv kev lag luam yas.

Kev faib tawm ntawm PE
Vim yog cov txheej txheem polymerization sib txawv ntawm polyethylene, nws cov qauv kuj txawv, thiab cov khoom sib xws kuj txawv heev. Feem ntau tuaj yeem muab faib ua: Low-Density Polyethylene (LDPE), Linear Low Density Polyethylene (LLDPE), High-Density Polyethylene (HDPE).
LDPE: Feem ntau siv rau cov ntawv hluavtaws, zaj duab xis ua liaj ua teb, zaj duab xis rau kev ntim khoom lag luam, hlau, thiab lwm yam;
LLDPE: Feem ntau yog siv rau cov xov hlau thiab cov cables, cov kav dej, cov khoom siv niaj hnub, thiab lwm yam;
HDPE: Feem ntau siv rau cov hlua khi, hlua khi, cov ntaub nuv ntses, thiab lwm yam.

 

Kev faib tawm ntawm PE lub peev xwm tsim khoom los ntawm lub teb chaws
Txij li lub Plaub Hlis 2022, Tuam Tshoj lub peev xwm tsim khoom PE tau txog li 29.18 lab tons, suav txog 21% ntawm lub ntiaj teb tag nrho lub peev xwm tsim khoom PE. Nws tuaj yeem pom los ntawm cov ntaub ntawv tias lub peev xwm tsim khoom PE thoob ntiaj teb feem ntau yog nyob hauv Tuam Tshoj, Tebchaws Meskas thiab Saudi Arabia. Tuam Tshoj tam sim no yog lub tebchaws uas muaj peev xwm tsim khoom polyethylene loj tshaj plaws hauv ntiaj teb.

 

 

Daim ntawv PE coated yog dab tsi?

Peb twb tau nkag siab tob txog PE saum toj no lawm, yog li ntawv PE coated yog dab tsi? Hauv qhov yooj yim, ntawv PE coated yog cov khoom sib xyaw ua los ntawm ntawv ua cov khoom siv hauv paus thiab coated nrog ib txheej ntawm zaj duab xis polyethylene rau ntawm daim ntawv hauv paus, uas yog, cov yas me me raug coated rau ntawm qhov chaw ntawm daim ntawv los ntawm lub tshuab casting. Daim ntawv yooj yim kom ntub, tab sis tom qab ua ke zoo kawg nkaus nrog polyethylene, daim ntawv coated tuaj yeem ua tiav cov teebmeem ntawm kev tiv thaiv dej, roj-pov thawj thiab kub siab.

Kev faib tawm ntawm PE coated ntawv

Raws li qhov sib txawv ntawm tus naj npawb ntawm cov zaj duab xis coated, nws muaj peev xwm muab faib ua ib daim ntawv coated PE ib sab, ob daim ntawv PE coated, thiab interlayer PE coated ntawv.

1. Daim ntawv PE coated ib sab
