EVA khau khiab yog tiv thaiv kev laus thiab tsw-resistant

EVA khoom yog tsim los ntawm copolymerization ntawm ethylene (E) thiab vinyl acetate (VA). EVA ua npuas ncauj ntawv muaj zoo softness thiab elasticity, thiab nto gloss thiab tshuaj stability kuj zoo heev. Cov qauv kaw ntawm tes, eva Cov khoom siv los tiv thaiv kev laus, tsw-resistant, tsis muaj tshuaj lom, mos, poob siab-absorbing thiab biodegradable, yog li nws muaj ntau yam kev siv.
Cov khoom siv hauv EVA khau khiab yog ethylene / vinyl acetate copolymer (tseem hu ua ethylene-vinyl acetate copolymer), uas yog tsim los ntawm copolymerizing ethylene (E) thiab vinyl acetate (VA). Lub npe lus Askiv yog: EthyleneVinylAcetate. Raws li EVA, cov ntsiab lus yog 5 feem pua ​​​​rau 40 feem pua. Piv nrog polyethylene, EVA yog dav siv hauv cov khau foamed vim yog kev qhia txog vinyl acetate monomer hauv cov saw molecular, uas txo cov crystallinity siab thiab txhim kho kev yooj yim, cuam tshuam tsis kam, muab tub lim thiab kev sib khi ua haujlwm kub. cov khoom siv, cov yeeb yaj kiab ua haujlwm, ntim zaj duab xis, kub yaj nplaum, xaim thiab cable, cov khoom ua si thiab lwm yam.
EVA yog ib qho khoom siv midsole feem ntau hu ua thawj ua npuas ncauj, uas muaj qee yam cushioning nyhuv, tab sis cov khoom no yog nplua heev, yog li nws feem ntau yog tov nrog cov roj hmab tawv.
1. Zaj duab xis, ntawv thiab laminated khoom: nrog sealing, adhesiveness, softness, toughness, thiab shrinkage, haum rau elastic ntim films, tshav kub shrinkable films, ua liaj ua teb films, zaub mov ntim films, laminated films, thiab yuav siv tau raws li nyob rau hauv nruab nrab txheej. ntawm polyolefin lamination zaj duab xis.
2. Cov khoom siv dav dav: Nws muaj qhov zoo ntawm kev yoog raws, ib puag ncig kev ntxhov siab tawg, thiab huab cua tsis zoo. Nws yog tsim rau kev lag luam cov ntaub ntawv xws li fais fab hlau rwb thaiv tsev foreskin, khoom siv hauv tsev, cov ntaub ntawv qhov rais sealing, thiab lwm yam.
3. Cov khoom noj txhua hnub muaj xws li cov khoom ua si, cov khoom ua si, cushions, txoj siv sia, lub thawv ntim ntim, EVA roj hmab ncaws pob, thiab lwm yam.
