EVA zaj duab xis muaj cov yam ntxwv zoo xws li yooj, adhesion, tawv (tshwj xeeb muaj kev cuam tshuam), tshav kub sealability, txias tsis kam, cov khoom kho qhov muag (ci, pob tshab, thiab lwm yam) thiab kev nyuaj siab tawg tsis kam. Kev siv nws cov yam ntxwv, nws yog dav siv hauv cov ntim hnyav, hloov khoom ntim, ntim khoom ntawm lub cev, ntim khoom ntawm lub cev, ncab ntim khoom thiab hnab ntim khoom.
(1) Lub hnab ntim khoom hnyav: EVA zaj duab xis yog siv los ua cov khoom ntim hnyav rau txawv teb chaws vim nws lub zog muaj cov tawv tawv, cov cua kub kom zoo, tiv thaiv txias thiab lwm yam ntxwv. EVA zaj duab xis siv rau cov ntim khoom hnyav muaj VA cov ntsiab lus ntawm 5% (feem ntau qhov feem), thiab nws cov kev ua tau zoo ib yam li LDPE, yog li muaj kev sib tw ntawm lawv. EVA muaj cov tawv zoo dua, tiv thaiv thaum tshav kub kub thiab txias txias dua li LDPE. Tus nqi ntawm EVA resin nyob rau hauv Suav teb yog qhov siab, yog li nws tsis siv rau hauv ntim hnyav.
(2) Ntim ntim tau yooj yim: Cov ntim ntim tau yooj yim kuj hu ua ntim tau yooj yim. Nws yog cov ntawv ntim khoom ntim sib xyaw ua ke ntawm EVA Zaj duab xis thiab lwm cov yeeb yaj kiab (xws li polypropylene, polyester, nylon, thiab lwm yam), cellophane, thiab txhuas ntawv ci, thiab yog siv rau cov zaub mov ntim. Nws siv txoj kab sib xyaw qhuav thiab extrusion compounding co-extrusion compounding txoj kev. Txij li VA cov ntsiab lus ntawm cov kev tiv thaiv zoo li no feem ntau qis dua 10% (qhov feem cuam ntawm qhov loj), lub zog, tawv, tawv thaum tshav kub kub, thiab qhov ua tau ntev ntawm ib puag ncig kev ntxhov siab ntawm EVA tau siv tag nrho. Vim tias kev txhim kho cov zaub mov ntim khoom rau automation thiab kev kub ceev, qhov yuav tsum tau ua rau kev ua tiav ntawm cov ntawv ntim khoom yog siab dua, tshwj xeeb tshaj yog qhov kev thov rau cov khoom ntim nrog cov tawv zoo thiab cov tshav kub ntim tau nce ntxiv.
(3) Cov kua ntim ua kua: Nws kuj siv cov yam ntxwv ntawm EVA Zaj duab xis ua kom tawv, thaum tshav kub ua kom pom tseeb, thiab ib puag ncig kev ntxhov siab kuj tawg. Nws yog siv rau cov kua ntim khoom ntawm cov roj muaj txiaj ntsig, vinegar, caw, tshuaj lag luam, tshuaj ntxuav tes, thiab lwm yam. Kev ntim khoom yog nyob rau hauv daim ntawv ntawm lub hnab hauv ib lub thawv lossis kraft ntawv thau sab hauv lub hnab hauv zos. Cov VA cov ntsiab lus ntawm EVA Zaj Dab Neeg feem ntau yog qis dua 10% (feem feem loj).
(4) Kev ntim lub cev: EVA muaj cov yam ntxwv ntawm lub siab mos, kev pom tseeb, kev ua kom tawv, thiab lwm yam, thiab tuaj yeem siv rau lub cev ntim. Qhov kev hloov kho qhov kub siab corona kho kev kho mob ntawm EVA Zaj duab xis yuav txhim kho sai sai rau kev kho kom zoo ntawm qhov chaw kho thiab cov duab los qhia. Txawm hais tias daim nplaum tsis lo rau ntawm daim duab los, nws tseem muaj cov nplaum zoo heev. Mas siv rau kev ntim khoom txhua hnub sundries, tab sis kuj tseem ntim ntim tshuab seem, cov cuab yeej, hluav taws xob qhov chaw, thiab lwm yam. Cov ncauj lus EVA siv nyob rau hauv cov haujlwm no feem ntau siab dua 10% (huab hwm coj feem ntau).
