Ethylene-vinyl acetate copolymer CAS 24937-78-8 (EVA) muaj ntau yam kev siv, cov hauv qab no yog nws cov chaw thov tseem ceeb:
Thaj teb zaj duab xis nyias
Zaj duab xis ua liaj ua teb: EVA muaj lub teeb ci zoo, tiv taus kub thiab tiv taus huab cua, thiab feem ntau siv rau hauv kev tsim cov zaj duab xis ua liaj ua teb. Nws tuaj yeem tswj tau qhov kub thiab txias hauv tsev cog khoom, txhawb kev loj hlob ntawm cov qoob loo, thiab txuas lub neej ua haujlwm ntawm zaj duab xis.
Zaj duab xis ntim khoom: Zaj duab xis EVA muaj kev ywj pheej zoo, pob tshab thiab tiv taus qhov tho, tsim nyog rau kev ntim khoom ntawm ntau yam khoom, xws li zaub mov, khoom siv niaj hnub, thiab lwm yam. Nws tuaj yeem muab kev tiv thaiv zoo thaum qhia txog cov tsos ntawm cov khoom.
Cov khoom siv khau
Cov hauv qab: EVA muaj cov yam ntxwv ntawm kev mos mos, zoo elasticity, lub teeb yuag, tiv taus kev hnav, thiab lwm yam, yog cov khoom zoo tshaj plaws rau kev ua cov hauv qab. Cov hauv qab ua los ntawm EVA yog xis hnav, muaj kev ua tau zoo ntawm kev poob siab, thiab tuaj yeem txo qhov nkees ntawm ko taw.
Sab saud: EVA kuj tseem siv tau los ua cov ntaub ntawv sab saud, muab kev kov mos thiab ua pa tau zoo, ua rau khau xis dua thiab zoo nkauj dua.
Kub yaj nplaum teb
Cov nplaum EVA kub yaj: muaj qhov zoo ntawm cov viscosity muaj zog, kho sai, tsis kub, thiab lwm yam, siv dav hauv kev ntim khoom, khi, tsim rooj tog thiab lwm yam lag luam. Siv tau los khi ntawv, ntoo, yas thiab lwm yam khoom siv, yooj yim rau kev khiav lag luam, tuaj yeem txhim kho kev ua haujlwm ntau lawm.
Hlau thiab cable teb
Txheej rwb thaiv tsev: EVA muaj kev ua tau zoo rwb thaiv tsev, tiv taus dej thiab tshuaj lom neeg corrosion, tuaj yeem siv ua cov khoom siv txheej rwb thaiv tsev rau hlau thiab cable, tuaj yeem tiv thaiv hlau thiab cable los ntawm kev cuam tshuam ntawm ib puag ncig sab nraud, kom ntseeg tau tias muaj kev nyab xeeb thiab kev ntseeg siab ntawm kev xa hluav taws xob.
Lub plhaub: EVA kuj tseem siv tau los ua lub plhaub rau hlau thiab cable, muab kev tiv thaiv tshuab thiab kev ua haujlwm tiv thaiv kev laus, txuas ntxiv lub neej kev pabcuam ntawm hlau thiab cable.
Lwm cov teb
Cov Khoom Ua Si: EVA yog mos, tsis muaj tshuaj lom, tsis muaj ntxhiab thiab lwm yam ntxwv, feem ntau siv los ua cov khoom ua si, xws li cov menyuam yaus cov khoom ua si pob, puzzles, thiab lwm yam, kom ntseeg tau tias muaj kev nyab xeeb thiab xis nyob ntawm cov menyuam yaus siv.
Cov khoom siv kis las: Nws kuj tseem siv dav hauv cov khoom siv kis las, xws li kev ua kis las MATS, yoga MATS, thiab lwm yam, uas nws qhov mos thiab elasticity tuaj yeem muab kev txhawb nqa zoo thiab cushioning effect.
Cov khoom ua npuas ncauj: EVA ua npuas ncauj muaj qhov hnyav sib dua, mos, tiv thaiv kub, rwb thaiv suab thiab lwm yam khoom, tuaj yeem siv los ua ntau yam khoom ua npuas ncauj.
