Ethylene Vinyl Acetate (EVA) ua npuas ncauj yog dav siv hauv khau, khoom siv ua kis las, cov ntaub ntawv ntim khoom, thiab ntau yam kev lag luam siv vim nws lub teeb yuag, yooj, thiab cushioning zog. Txawm li cas los xij, tsis yog txhua yam khoom siv EVA ua npuas ncauj muaj tib theem ntawm kev ua haujlwm ntev. Kev nkag siab txog yam tseem ceeb uas cuam tshuam rau EVA ua npuas ncauj ua haujlwm tuaj yeem pab cov tuam txhab lag luam thiab cov neeg yuav khoom xaiv cov khoom tsim nyog tshaj plaws rau lawv daim ntawv thov.
Ib qho tseem ceeb tshaj plaws yog qhov zoo ntawm cov khoom siv raw. Siab - zoo EVA resin muab zoo elasticity, resilience, thiab tsis kam mus deformation. Cov ntsiab lus Vinyl Acetate (VA) kuj ua lub luag haujlwm tseem ceeb. EVA cov ntaub ntawv nrog cov qib VA uas tsim nyog yuav ua rau muaj kev hloov pauv tau yooj yim thiab cuam tshuam rau kev nqus thaum tswj kev ua haujlwm zoo.
Qhov ceev yog lwm qhov tseem ceeb. Siab dua -Qhov ceev EVA ua npuas ncauj feem ntau pom zoo hnav tsis kam thiab rov ua kom rov zoo dua. Nws tuaj yeem tiv taus rov siv dua yam tsis tau poob nws cov qauv qub, ua rau nws zoo tagnrho rau khau khau thiab tiv thaiv padding.
Cov txheej txheem tsim khoom zoo heev cuam tshuam rau durability thiab. Kev siv tshuab ua npuas dej kom zoo, tswj qhov kub thiab txias, thiab hla -txoj kev sib txuas ua rau muaj cov qauv ntawm tes zoo dua. Cov qauv ua npuas dej zoo ib yam txhim kho lub zog thiab txo qhov kev pheej hmoo ntawm kev tawg lossis kev laus ntxov ntxov.
Ib puag ncig tej yam kev mob yuav tsum tau xav txog. Nruam raug UV hluav taws xob, huab cua kub, ya raws, lossis tshuaj tuaj yeem ua kom cov khoom degradation. Cov neeg tsim khoom feem ntau suav nrog cov khoom ntxiv xws li UV stabilizers thiab tiv thaiv - cov neeg ua haujlwm laus los txhim kho kev ua haujlwm ntev -.
Thaum kawg, cov khoom tsim thiab npaj daim ntawv thov cuam tshuam rau lub neej ua haujlwm. EVA ua npuas ncauj siv nyob rau hauv siab - qhov cuam tshuam ib puag ncig yuav tsum muaj qhov tshwj xeeb sib txawv dua li ua npuas ncauj siv rau ntim lossis rwb thaiv tsev lub hom phiaj.
Los ntawm kev ua tib zoo tswj cov khoom xaiv, cov txheej txheem tsim khoom, thiab cov ntawv thov, cov tuam txhab tuaj yeem txhim kho EVA ua npuas ncauj kom ruaj khov thiab xa cov khoom lag luam uas ua tau raws sijhawm.
