EVA ua npuas ncauj tau siv dav hauv ntau lub teb vim nws qhov kev ua tau zoo tshaj. Kab lus no yuav muab cov ncauj lus qhia ntxaws ntxaws txog cov yam ntxwv ntawm EVA ua npuas ncauj thiab tshuaj xyuas cov kev cov nyom uas tau ntsib hauv ntau daim ntawv thov.
EVA cov khoom, tseem hu ua ethylene vinyl acetate copolymer, muaj elasticity zoo, yooj, thiab cuam tshuam tsis kam, ua rau nws siv dav hauv kev lag luam xws li shoemaking, ntim, electronics, thiab cov khoom ua si. EVA ua npuas yog cov khoom siv ua npuas ncauj kaw, uas muaj cov yam ntxwv ntawm lub teeb yuag, muaj zog, noo noo tsis kam thiab poob siab tsis kam. Nyob rau tib lub sijhawm, EVA ua npuas ncauj kuj muaj qhov zoo heev UV tsis kam thiab tshuaj tiv thaiv corrosion, uas ua rau nws muaj peev xwm tswj tau lub cev zoo thiab cov khoom siv kho tshuab txawm nyob rau hauv ib puag ncig hnyav.
1. Kev sib tw ntawm EVA hauv ob sab phlu hauv kev ntim khoom
Hauv kev ntim khoom, EVA hauv ob sab phlu yog dav siv rau ntim cov khoom siv hluav taws xob, cov cuab yeej precision, thiab cov khoom iav vim nws cov cushioning zoo heev thiab kev poob siab. Txawm li cas los xij, EVA ua npuas ncauj yuav tsum tau ntsib teeb meem ntawm kev hloov pauv kub thiab av noo cuam tshuam hauv daim ntawv thov no. Nyob rau hauv ib puag ncig kub, EVA yuav soften, txo nws cov nyhuv tiv thaiv. Yog li ntawd, txhawm rau txhim kho nws qhov kub thiab txias, cov khoom siv tshwj xeeb feem ntau yog ntxiv rau cov mis.
2. Kev sib tw ntawm EVA hauv ob sab phlu hauv cov khoom ua si
Hauv cov khoom siv kis las, EVA hauv ob sab phlu yog siv dav hauv cov kaus mom hlau, cov iav tiv thaiv, lev thiab lwm yam khoom. Rau cov khoom no, EVA ua npuas ncauj yuav tsum tau muab kev tiv thaiv thaum ua kom muaj kev nplij siab. Txawm li cas los xij, compression deformation thiab hnav tom qab siv ntev yog cov teeb meem tseem ceeb hauv daim teb no. Yog li ntawd, xaiv EVA cov ntaub ntawv nrog kev ntom ntom siab thiab siab muaj peev xwm txhim kho lawv lub neej kev pabcuam thiab xis nyob.
3. Kev sib tw ntawm EVA ua npuas ncauj hauv kev tsim kho kev lag luam
Txawm hais tias EVA ua npuas ncauj feem ntau yog siv los ua cov khoom siv dej tsis zoo thiab tiv thaiv cov dej hauv kev tsim kho, cov teeb meem kev laus thiab UV tiv thaiv hauv ib puag ncig tseem yuav tsum tau hais ntxiv. Ntxiv cov tshuaj tiv thaiv kev laus thiab ultraviolet absorber yog ib txoj hauv kev zoo los daws cov teeb meem tam sim no. Txawm li cas los xij, tus nqi ntawm cov additives no kuj ua rau muaj kev kub ntxhov rau cov tuam txhab tsim khoom.
Nyob rau hauv luv luv, EVA ua npuas ncauj tau ua tau zoo nyob rau hauv ntau lub teb vim nws cov yam ntxwv tshwj xeeb, tab sis nws kuj ntsib ntau yam kev cov nyom nyob rau hauv kev siv cov tswv yim. Los ntawm kev txhim kho cov khoom sib piv, txhim kho cov txheej txheem tsim khoom, thiab qhia cov khoom siv ua haujlwm siab, peb tuaj yeem ua kom nws qhov zoo tshaj plaws thiab ua tau raws li cov kev xav tau tshwj xeeb ntawm ntau qhov chaw.
