1. Kev kho sai thiab yooj yim cia
EVA Zaj duab xis yog khoom rau qhov kub li qub. Thaum rhuab thiab yaj mus rau ib qho kub, nws dhau los ua kua ntxig. Lub colloid yog cais tawm los ntawm lub cuab yeej cua sov thiab txias kom lub ntsiab lus melting, thiab tom qab ntawd ua lub zog sai (tom qab ua tawv tawv, nws dhau los ua cov kua nplaum qub). Vim tias qhov chaw melting kis ntawm colloid yog siab (feem ntau ntawm 80 ℃), nws yog nyob rau hauv lub xeev khov ntawm chav sov. Cov khoom ntim tau yooj yim thiab yooj yim cia. Lub sijhawm khaws cia yog feem ntau kwv yees li ib thiab ib nrab xyoo.
2. Tsis tshua muaj kuab paug thiab muaj zog adhesion
EVA Film muaj tus ntxhiab tsw ntxhiab thaum nws yaj mus ua kua, thiab cov khoom siv dav dav yog nruab nrog ib qho khoom siv uas nqus cov ntxhiab, yog li nws tsis muaj teeb meem rau tib neeg lub cev. Vim tias lub siab yaj npliag ntawm cov kua nplaum no, yuav tsis muaj ib qho kev ua qias tuaj ib puag ncig los ntawm qhov ua kom tsis muaj lub colloid. Cov nplaum txheej ntawm EVA Zaj duab xis muaj ob qho tib si qee qhov hloov tau thiab ib qho tawv tawv. Nws yog qhov ruaj thiab ruaj khov tom qab kev cog lus, thiab yog qhov tsim nyog rau kev ua tiav hauv ntau zaus.
3. Muaj cov khoom rov ntxiv dua tshiab
Tom qab EVA Zaj Duab Xis ntawm cov khoom siv khov kho yog kho lossis txias thiab ua kom tawv tawv, nws tuaj yeem ua kom mos muag los ntawm cua sov saum cov nplauv melting, thiab nws dhau los ua kua dej ua kua nrog qhov nce ntawm qhov kub ntawm cov kua nplaum, thiab tom qab ntawd rov viscosity yog rov qab. Thaum muaj qhov tsis xws xws li qhov tsis meej thiab tsis sib xws tshwm sim thaum lub sijhawm ua, cov nplaum lo tuaj yeem nyob hauv zos, kho qhov chaw thiab tom qab ntawd sib txuas rau cov khoom tiav uas ua tau raws li qhov yuav tsum tau ua.
4. Siv tau yooj yim
Thaum siv EVA Zaj Duab Xis, koj tsuas yog xav tau ua kom sov lub nplaum ua kom nws cov kua nplaum ua kua nrog qhov yuav tsum muaj viscosity. Tom qab ua kom huv si, clamped thiab nias ua ke, kev sib khi thiab kho tuaj yeem ua tiav nyob hauv ob peb feeb, thiab cov tawv tawv, ua kom txias thiab ziab tuaj yeem ua tiav hauv 2 rau 3 feeb.
