Khoom nta:
EVOH npaj txoj kev: thawj zaug copolymerize ethylene thiab yas acetate, thiab tom qab ntawd hydrolyze lub copolymer kom tau ethylene-vinyl cawv. Yog li ntawd, qhov siab ntawm qhov cuam tshuam tseem ceeb tseem khaws cia, thiab muaj kev txhim kho tseem ceeb hauv kev ya raws thiab kev ua haujlwm.
Cov khoom siv tshuaj: Hais txog cov khoom, EVOH copolymer yog crystalline heev, thiab nws cov khoom feem ntau yog nyob ntawm qhov txheeb ze concentration ntawm nws cov comonomers. Feem ntau hais lus, thaum cov ntsiab lus ethylene nce, cov roj barrier kev ua tau zoo txo qis, kev ua haujlwm tsis zoo ntawm cov dej noo, thiab cov resin yooj yim dua rau kev ua haujlwm. Qhov tseem ceeb tshaj plaws ntawm EVOH cob yog nws cov roj barrier nyhuv. Nws yog siv nyob rau hauv cov qauv ntim los txhim kho qhov tuav ntawm cov tshuaj tsw qab thiab zoo los ntawm kev tiv thaiv cov infiltration ntawm oxygen. Hauv kev siv cov tshuab ntim tshuab, EVOH resin zoo khaws cov pa roj carbon dioxide lossis nitrogen siv los tiv thaiv cov khoom. Vim muaj cov pab pawg hydroxyl hauv cov qauv molecular ntawm EVOH resin, EVOH resin yog hydrophilic thiab hygroscopic. Thaum ya raws yog absorbed, cov roj barrier kev ua tau zoo yuav cuam tshuam. Txawm li cas los xij, cov ntsiab lus noo noo nyob rau hauv txheej txheej barrier tuaj yeem ua tib zoo tswj. Qhov no tuaj yeem ua tiav los ntawm kev qhwv EVOH resin txheej nrog lub zog noo noo thaiv cov khoom siv xws li polyolefin siv cov txheej txheem multilayer.
Roj tsis kam: EVOH resin kuj muaj cov roj muaj zog thiab cov organic hnyav tsis kam. Tom qab muab tso rau hauv ntau cov kuab tshuaj thiab cov roj ntawm 68 ° F rau 1 xyoos, qhov feem pua ntawm qhov hnyav nce yog: 0% rau cov kuab tshuaj xws li cyclohexane, xylene, roj av ether, benzene thiab acetone, thiab 2.3 rau ethylene glycol. %, rau methanol yog 12. 2%, 0 rau zaub nyoos roj. 1%.
Thermal/mechanical zog: EVOH resin muaj zog txhua yam, elasticity, nto hardness, hnav tsis kam thiab huab cua tsis kam, thiab muaj zog antistatic zog. EVOH zaj duab xis muaj siab gloss thiab tsis tshua muaj haze, yog li nws yog pob tshab heev. EVOH resin yog cov resin nrog siab tshaj thermal stability ntawm tag nrho cov lag luam muaj zog barrier resins. Cov cuab yeej no tso cai rau cov khoom pov tseg thaum lub sij hawm ua kom rov ua dua thiab rov siv dua. Cov khoom siv rov ua dua muaj ntau dua 20% EVOH.
Kev Ua Haujlwm: Muaj peb txoj hauv kev los siv EVOH los muab kev cuam tshuam hauv ntau txheej txheej. Lawv yog: co-extrusion qauv. EVOH resin yog ua ke nrog polyolefin los yog polyphenol amine los tsim ib lub moj khaum; EVOH zaj duab xis yog laminated rau lwm cov substrates, los yog lwm yam ntaub ntawv yog siv los coatings; EVOH resin yog siv los ua txheej rau ntau yam substrates lossis ib txheej ntim ntim; tsis tas yuav hloov tshwj xeeb. Nws tuaj yeem ua tau yooj yim ntawm cov cuab yeej tsim khoom siv.
Siv cov khoom lag luam, EVOH resin yog tsim rau kev ua haujlwm hauv qab no: ib txheej lossis ntau txheej zaj duab xis extrusion; ntawv thiab profile co-extrusion; co-extrusion tshuab molding; co-extrusion txheej; lamination (los yog lamination) thiab txhaj tshuaj molding. Kev ua haujlwm thib ob ntawm EVOH resin thav duab lossis EVOH zaj duab xis, xws li thermoforming, lub tshuab nqus tsev tsim thiab luam ntawv, tuaj yeem ua tau yooj yim. Zoo li lwm yam polymers, EVOH resin tuaj yeem hloov kho los ntawm kev kub dhau. Cov txheej txheem txheej txheem suav nrog ntau txheej txheej lossis co-extrusion txheej kuj tuaj yeem siv los tsim cov txheej txheem ntau txheej, thiab cov qauv tsim tau zoo heev rau cov qauv co-extrusion. Nws tuaj yeem txau nrog EVOH resin, immersed lossis nruas coated. Txhawm rau tsim cov thawv ntim rau cov dej haus carbonated los yog ua tiav lub hom phiaj ntawm kev thaiv cov kuab tshuaj, cov txuj lom lossis cov ntxhiab tsw. EVOH resin tsis zoo adhesion rau feem ntau cov polymers. Yuav kom kov yeej qhov teeb meem no, tshwj xeeb tsim cov khoom sib txuas los yog" txuas cob" yuav tsum tau siv. Tsuas yog cov nylon, EVOH resin tuaj yeem ua tau zoo rau nylon yam tsis siv cov nplaum nplaum.
Txoj kev loj hlob tshiab: Nrog rau kev loj hlob ntawm cov khoom ntim yas, cov txheej txheem siab, kev ua haujlwm tshiab tau muab tso rau pem hauv ntej rau EVOH resin. Txhawm rau ua kom tau raws li cov kev xav tau no, EVOH cov chaw muag khoom muab qee cov khoom lag luam, xws li J102 (EVAL Corporation-EVALCA hauv Tebchaws Meskas) thiab ST series khoom los ntawm Goshei hauv Nyiv. Cov khoom no tau txhim kho kev ua tau zoo thiab muaj ntau yam molding. Lwm cov khoom lag luam, xws li F100 thiab E151 los ntawm EVAL Corporation ntawm Tebchaws Meskas, kuj tau tsim, uas muaj cov viscosity zoo dua thiab zoo sib xws nrog cov khoom siv polyolefins uas siv rau hauv cov thawv nruj. Hauv kev tsim cov yas rov ua dua tshiab, EVOH resin muaj qhov zoo dua. Siv HDPE lub raj mis thiab lub raj mis ntau txheej (muaj EVOH resin) yog sib xyaw ua ke los tsim cov ntim khoom tsis yog khoom noj.
Daim ntawv thov: Cov txheej txheem txheej txheem uas muaj EVOH resin yog siv rau hauv txhua lub ntim nyuaj thiab hloov tau yooj yim thiab txhua hom kev ua zaub mov suav nrog aseptic, tshuaj tua hluav taws kub thiab ua noj ua haus. Cov khoom ntim nrog EVOH cov ntaub ntawv muaj xws li: condiments (soy sauce), lws suav sauce, kua txiv, edible batter, nqaij cov khoom, cheese khoom thiab cov txiv hmab txiv ntoo tiav. Cov ntawv thov uas tsis yog khoom noj muaj xws li cov kuab tshuaj, tshuaj, thiab cov khoom lag luam ntsig txog kev ntim tshuaj. Cov neeg tsim khoom ntawm cov roj tso tsheb hlau luam, cov kav dej roj, thiab cov cuab yeej siv cua txias rau lub cev muaj zog tau soj ntsuam seb puas yuav siv cov qauv EVOH los txo cov pa roj carbon monoxide thiab / lossis Freon emissions.
