Kev qhia dav rau Eva ua npuas dej: Cov ntawv thov, cov txiaj ntsig, thiab ntau lawm
EVA ua npuas ncauj moulding
Cov tshuab ua npuas ncauj eva yog ib qho kev siv yas ua ib txwm siv los tsim ntau yam khoom ntim ntim, Cheebtsam, khoom ua si, thiab lwm yam. EVA ua npuas ncauj cov ntaub ntawv pom tias zoo tshaj plaws cushioning zoo heev, softing, thermal rwb thaiv tsev, thiab dej tsis tau, ua rau lawv muaj feem dav hla ntau daim teb.
Lub ntsiab
Thawj cov khoom xyaw nyob rau hauv Eva ua npuas yog Eva Resin, uas yog cov ethylene-vinyl acetate copolymer. Txhawm rau txhim kho cov khoom siv lub cev ntawm cov khoom lag luam, lwm cov ntaub ntawv xws li roj hmab thiab poe (polyolefin elastomer) tuaj yeem ntxiv. Tus Va (Vinyl acetate) cov ntsiab lus hauv Eva yog qhov ntsuas qhov tseem ceeb, cuam tshuam rau kev ua tau zoo ntawm cov khoom lag luam.
Ntxiv
Nyob rau hauv eva ua npuas ncauj tsim qauv, fillers nyiam calcium carbonate lossis talcum hmoov feem ntau siv los txo cov nqi thiab nce khoom nruj. Cov ua npuas ncauj yog feem ntau muaj cov tshuaj tiv thaiv foaming siab los ntawm AC series, xws li ac {1}} h, txawm tias cov neeg sawv cev tsawg thiab nruab nrab. Hla-txuas cov neeg sawv cev feem ntau siv suav nrog DCP (dicumyl peroxide). Rau cov khoom lag luam nrog cov ntxhiab tsw tshwj xeeb, BIPB (Bis (isopropyl) benzene) thiab Taic (tsis raug cai yog siv ua ke. Cov neeg txhawb nqa ua npuas ncauj suav nrog zinc oxide hmoov thiab zinc stearinate hmoov, thaum lubricants siv tau yog ntub los ntawm cov khoom sib xyaw rau cov tshuab ua haujlwm.
Txheej Txheem Cov yam ntxwv
Cov ntaub ntawv ua npuas ncauj tau muaj cov qauv microcellular nplua nuj uas tuaj yeem nqus thiab tawg cov kev cuam tshuam sab nraud, tiv thaiv cov khoom ntim los ntawm kev puas tsuaj. Lawv qhov muag muag thiab thermal ua rau lawv yooj yim rau cov txheej txheem rau hauv ntau yam duab, ntsib cov kev xav tau ntim ntau. Ib qho ntxiv, cov ntaub ntawv ua npuas ncauj tau muaj cov dej noo zoo, ua rau lawv tiv taus dampness thiab deformation, uas tau txais txiaj ntsig rau lub sijhawm ntev thiab siv.
Hauv cov ntsiab lus, EVA ua npuas ncauj cov ntaub ntawv nyob ib txoj haujlwm tseem ceeb hauv cov tshuab yas ua kom zoo nkauj vim lawv cov kev siv zoo tshaj plaws. Los ntawm kev kho cov qauv thiab cov txheej txheem tsis zoo, kev ua haujlwm ntawm cov ntaub ntawv ua npuas ncauj xa tuaj yeem ua tau zoo ntxiv kom tau raws li qhov xav tau ntawm kev thov ntau dua.
