PERT EVOH Tube

Kev piav qhia

EVOH ib txwm yog cov khoom siv dav dav tshaj plaws - cov khoom thaiv. Ntxiv rau qhov tsis yog -stretch type, zaj duab xis hom ntawm cov khoom no muaj xws li ob-txoj kev stretch type, aluminium vapor deposition type, nplaum txheej, thiab lwm yam. Ntawm ob-txoj kev stretch hom, tshav kub- hom resistant yog siv rau aseptic ntim khoom. Qhov barrier kev ua tau zoo ntawm EVOH nyob ntawm cov ntsiab lus ntawm ethylene. Feem ntau hais lus, thaum cov ntsiab lus ntawm ethylene nce, cov roj barrier zog txo, tab sis nws yog ib qho yooj yim rau txheej txheem. Qhov tseem ceeb ntawm PERT EVOH Yeeb Nkab yog tias nws muaj cov khoom siv roj zoo heev thiab muaj peev xwm ua tau zoo heev. Tsis tas li ntawd, nws muaj cov pob tshab zoo heev, gloss, txhua yam muaj zog, elasticity, abrasion tsis kam, txias tsis kam thiab lub zog saum npoo.

Qhov zoo

Thaum xyoo 1980s, cov kws tshaj lij pom tau tias nyob rau hauv cov dej kub uas siv cov kav dej yas, cov hlau hauv cov khoom siv tau yooj yim corroded, ua rau cov khoom puas tsuaj sai. Xyoo 1982, cov kws tshaj lij tau txiav txim siab tias thaum cov yeeb nkab yog cua sov, cov pa oxygen molecules yuav yooj yim nkag mus rau hauv cov txheej txheem yas thiab nkag mus rau hauv cov dej hauv cov yeeb nkab, uas ua rau corrosion sai ntawm cov hlau hauv cov khoom siv. Yog li ntawd, cov pa oxygen barrier raj tau tsim.

Kev siv tus nqi ntawm cov pa oxygen-cov kav xa dej hauv cov cua sov mus txog 70 feem pua. Tom qab ze li ntawm ob xyoo caum ntawm kev ua tau zoo, lub neej ntawm cov khoom siv hlau hauv cov pa oxygen -txoj kev thaiv cov kav dej tuaj yeem txuas ntxiv los ntawm 10-20 xyoo.

Nta

1.Oxygen barrier. Extend lub neej kev pab cuam ntawm lub system. EVOH tiv thaiv cov pa oxygen los ntawm kev nkag mus rau hauv dej lossis huab cua hauv cov yeeb nkab, ua kom lub neej ntev kev pab cuam ntawm cov hlau li qub, keyboards, boilers, manifolds thiab lwm yam hlau hauv tag nrho cov kav dej.

2. Kev noj qab haus huv. Txij li thaum infiltration ntawm oxygen tsim nyog rau kev ciaj sia ntawm cov kab mob yog tiv thaiv, lub hav zoov ntawm cov kab mob nyob rau hauv lub system yog inhibited.

3.Cov pa oxygen barrier raj kuj muaj qhov zoo ntawm kev tiv thaiv corrosion, tsis yog - scaling, tsis tshua muaj cua sov, txuag hluav taws xob thiab kev tiv thaiv ib puag ncig, hloov tau yooj yim thiab khoov tau yooj yim, kev ua haujlwm zoo ntawm cov tshuab ua haujlwm, thiab lub neej ntev ntawm lwm yam siab { {2}}kub hauv pem teb cua sov kav.

4.PERT EVOH Yeeb Nkab muaj qhov zoo toughness, loj dabtsi yog khoov vojvoog, tsis siv neeg siv, thiab yooj yim siv.

5.PERT EVOH Yeeb Nkab muaj cov khoom zoo oxygen barrier, uas tuaj yeem ncua kev xeb ntawm cov hlau hauv qhov system, ua kom ntev kev pab cuam lub neej ntawm cov hlau qhov chaw, thiab txo qhov scaling ntawm cov kav dej. Feem ntau siv nyob rau hauv ntau lub tshuab cua sov.
