EVOH Resin Ib Qho Kev Hloov Pauv Hauv Kev Dais Teeb Meem Ntim Khoom

EVOH (Ethylene Vinyl Cawv) cov roj hmab tau dhau los ua cov khoom siv tseem ceeb hauv kev lag luam ntim khoom, feem ntau yog vim nws cov khoom tiv thaiv zoo heev. Cov polymer thermoplastic no tau lees paub dav dav rau nws lub peev xwm tshwj xeeb los tiv taus cov pa roj xws li oxygen, carbon dioxide, thiab cov organic sib xyaw ua ke. Nyob rau xyoo tas los no, kev thov thoob ntiaj teb rau cov ntim khoom ua tau zoo tau nce siab, tsav los ntawm kev hloov pauv ntawm cov neeg siv khoom nyiam thiab qhov xav tau kev khaws cia zoo dua ntawm cov khoom noj.

Ib qho ntawm cov txiaj ntsig tseem ceeb tshaj plaws ntawm Evoh Resin yog nws lub peev xwm los khaws cov khoom noj tshiab thiab zoo. Hauv kev lag luam uas lub sijhawm txee yog qhov tseem ceeb, kev siv EVOH hauv kev ntim khoom noj tso cai rau cov chaw tsim khoom kom txo cov nqi lwj, yog li txo cov khib nyiab. Qhov no tau dhau los ua qhov tseem ceeb dua thaum cov lag luam zaub mov thoob ntiaj teb tab tom daws teeb meem kev ruaj khov. Thaum cov neeg siv khoom nyiam cov khoom uas tuaj yeem ua pov thawj tias muaj cov pa roj carbon tsawg dua, cov tuam txhab uas suav nrog EVOH hauv lawv cov kev daws teeb meem ntim khoom yuav tau txais kev sib tw zoo dua.

Cov neeg ua si loj hauv kev lag luam khoom noj thiab dej haus tab tom nqis peev ntau rau hauv EVOH thev naus laus zis. Piv txwv li, cov tuam txhab loj xws li Amcor thiab Sealed Air pheej tsim cov kev daws teeb meem ntim khoom tshiab uas suav nrog cov khaubncaws sab nraud povtseg EVOH. Qhov no tsis yog tsuas yog txhim kho kev ua tau zoo ntawm lawv cov khoom xwb tab sis kuj ua raws li cov kev coj ua zoo rau ib puag ncig los ntawm kev siv cov khoom siv rov ua dua tshiab.

Ntxiv rau kev lag luam zaub mov, lwm cov lag luam xws li tshuaj thiab tshuaj pleev ib ce kuj tau txais txiaj ntsig los ntawm EVOH cov khoom. Lub peev xwm los tiv thaiv kom tsis txhob muaj dej noo ua rau EVOH yog qhov kev xaiv zoo tshaj plaws rau kev ntim cov tshuaj rhiab heev thiab cov khoom siv pleev ib ce zoo. Raws li cov txheej txheem kev kho mob nrhiav kev txhim kho cov txiaj ntsig ntawm tus neeg mob thaum tswj hwm kev siv nyiaj txiag, qhov kev thov rau kev ntim khoom txhim khu kev qha thiab zoo yuav txuas ntxiv nce siab.

Txawm hais tias nws muaj ntau yam zoo, kev lag luam EVOH resin ntsib teeb meem. Tus nqi tsim khoom tseem yog qhov teeb meem loj heev, tshwj xeeb tshaj yog thaum sim sib tw nrog cov ntaub ntawv ntim khoom ib txwm muaj xws li polyethylene thiab polypropylene. Txawm li cas los xij, nrog kev tshawb fawb thiab kev nce qib ntawm thev naus laus zis, qhov sib txawv ntawm tus nqi yuav nqaim dua li xyoo tom ntej, ua rau EVOH yog qhov kev xaiv yooj yim dua rau txhua tus neeg tsim khoom.

Hauv kev xaus lus, EVOH resin tab tom hloov pauv kev lag luam ntim khoom nrog nws cov khoom zoo tshaj plaws thiab cov ntaub ntawv pov thawj kev ruaj khov. Nws yog qhov tseem ceeb rau cov lag luam kom nyob twj ywm rau qhov kev hloov pauv no kom siv tau cov txiaj ntsig ntawm EVOH thev naus laus zis hauv lawv cov saw hlau. Thaum cov neeg siv khoom paub txog thiab xav tau cov kev xaiv ruaj khov loj hlob, EVOH lub luag haujlwm hauv kev ntim khoom yuav tseem ceeb dua.
