PE yog dab tsi?
Ua ntej nkag siab PE coated ntawv, cia peb tham txog nws cov khoom tseem ceeb - polyethylene.Polyethylene luv luv rau PE, uas yog cov thermoplastic resin polymerized los ntawm ethylene.Cov tsos ntawm polyethylene yog milky dawb waxy hais, uas yog tasteless, odorless, non-toxic thiab zoo li siv quav ciab.Lub ntsiab feature ntawm polyethylene yog pheej yig, uas muaj zoo heev txias kuj, tshuaj stability, hluav taws xob rwb thaiv tsev thiab lwm yam ntxwv.Yog li nws muaj ntau yam kev siv ntau heev.Feem ntau yog siv rau hauv kev tsim cov yeeb yaj kiab, ntim khoom, ntim, kav, xov hlau thiab cables, khoom siv txhua hnub, thiab lwm yam. Tsis tas li ntawd, nws tuaj yeem siv los ua cov khoom siv hluav taws xob ntau zaus rau TV, radars, thiab lwm yam txij li nws daim ntawv thov xyoo 1922, polyethylene tau tsim los rau hauv lub ntiaj teb cov khoom siv hluavtaws loj tshaj plaws thiab siv ntau tshaj plaws ntawm cov khoom ntim yas.Nws tuav lub luag haujlwm tseem ceeb hauv kev lag luam plastics.
Classification PE
Vim muaj 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 yog siv rau cov ntawv hluavtaws, zaj duab xis ua liaj ua teb, zaj duab xis rau kev ntim khoom, xaim, thiab lwm yam;
LLDPE: Feem ntau yog siv rau cov xov hlau thiab cables, kav dej, khoom siv txhua hnub, thiab lwm yam;
HDPE: Feem ntau yog siv rau cov hlua, hlua, nuv ntses nets, thiab lwm yam.
Kev faib tawm ntawm PE ntau lawm muaj peev xwm los ntawm lub teb chaws
Raws li lub Plaub Hlis 2022, Tuam Tshoj lub peev xwm PE tsim tau txog li 29.18 lab tons, suav txog 21% ntawm lub ntiaj teb tag nrho cov peev txheej PE.Nws tuaj yeem pom los ntawm cov ntaub ntawv hais tias lub ntiaj teb PE muaj peev xwm ntau lawm yog nyob hauv Suav teb, Tebchaws Meskas thiab Saudi Arabia.Tuam Tshoj tam sim no yog lub teb chaws uas muaj peev xwm ntau tshaj plaws ntawm polyethylene hauv ntiaj teb.
PE coated ntawv yog dab tsi?
Peb twb muaj kev nkag siab tob txog PE saum toj no, yog li cas PE coated ntawv?Yooj yim muab, PE coated ntawv yog cov khoom sib xyaw ua los ntawm cov ntawv ua cov khoom siv hauv paus thiab coated nrog ib txheej ntawm polyethylene zaj duab xis rau ntawm daim ntawv, uas yog, cov khoom yas yog coated rau ntawm daim ntawv los ntawm lub tshuab casting.Daim ntawv yog ib qho yooj yim kom ntub dej, tab sis tom qab ua zoo tag nrho nrog polyethylene, coated ntawv tuaj yeem ua tiav cov teebmeem ntawm cov dej tsis zoo, roj-pov thawj thiab kub-resistant.
Kev faib tawm ntawm PE coated ntawv
Raws li qhov sib txawv ntawm tus naj npawb ntawm cov zaj duab xis coated, nws tuaj yeem muab faib ua ib sab PE coated ntawv, ob sab PEcoated ntawv, thiab interlayer PE coated ntawv.
1. Ib sab PE coated ntawv
Ib sab PEcoated ntawv yog coated nrog PE zaj duab xis ntawm ib sab ntawm daim ntawv hauv paus.Nws yog siv nyob rau hauv kub haus ntawv khob, hamburger ntawv, thiab lwm yam.
2. Ob sab PE coated ntawv
Ob sab PE coated ntawv yog PE txheej ntawm ob sab ntawm daim ntawv hauv paus.Nws yog siv nyob rau hauv txias haus ntawv khob.
Interlayer coated ntawv
Sandwich coated ntawv yog muab PE txheej ntawm ob lub hauv paus ntawv los ua ke ib daim ntawv los txhim kho qhov yooj ntawm daim ntawv.
Feem ntau siv nyob rau hauv: desiccant ntim, ntim zaub mov, thiab lwm yam.
Raws li cov txheej txheem sib txawv, nws tuaj yeem muab faib ua ob hom: ci zaj duab xis thiab sub-film.
Bright zaj duab xis yog pob tshab ob sab polyethylene zaj duab xis nrog ci ntsa iab thiab txhais tes du.matte zaj duab xis yog matte polyethylene zaj duab xis nrog matte zaj duab xis nrog ib tug fogged nto.
Cov sequins muaj cov ntsiab lus siab thiab cov ntawv luam tawm muaj xim ntau dua.Matte films yog ntau muted nyob rau hauv cov xim.
Kev siv cov ntawv coated
Cov ntawv coated yog ze rau peb lub neej txhua hnub thiab muaj ntau yam kev siv, feem ntau yog siv rau hauv ntim, khoom noj khoom haus, kev kho mob, electronics, hardware, tuag txiav, thiab lwm yam.
Daim ntawv thov Scope ntawm coated ntawv:
Scope ntawm kev siv cov ntawv coated
1. Tshuaj: desiccant ntim, npauj npaim, ntxuav hmoov, tshuaj tua kab mob.
2. Khoom noj khoom haus: noodle bundles, ice cream ntim, mis nyuj.
