EVA ua npuas ncauj yog tias koj tus neeg siv khoom yog tus neeg nyiam ua kis las, tej zaum yuav tsis muaj cov khoom siv cushioning zoo dua li EVA uas ua rau muaj txiaj ntsig zoo ntawm cov kiv cua dav tshaj plaws.

Yog tias koj tus neeg siv khoom yog tus neeg nyiam ua kis las, tej zaum yuav tsis muaj cov khoom siv cushioning zoo dua li EVA uas ua rau muaj txiaj ntsig zoo ntawm cov kiv cua dav tshaj plaws.

Thaum hloov khoom siv los ntawm ib qho chaw mus rau lwm qhov, kev poob los ntawm kev sib tw thiab kev cuam tshuam yog yam tsis muaj kev zam.Txawm li cas los xij, koj tuaj yeem txo qhov kev cuam tshuam no los ntawm kev siv lub cushioned EVA ua npuas ncauj thiab nqa cov khoom no rau koj cov khoom ntawm staples, yoga lev, khau ntaub, ntaub thaiv npog, " armored riam phom ", kaus mom hlau ......

EVA, ua lub neej zoo, tiv thaiv lub neej kom nyab xeeb.

EVA, ethylene-vinyl acetate, tseem hu ua poly (ethylene-vinyl acetate, PEVA), yog copolymer ntawm ethylene thiab yas acetate.Hais txog kev hloov pauv, nws nyob ze rau elastomer, yog li nws feem ntau hu ua cov roj hmab nthuav dav, EVA ua npuas ncauj, thiab cov roj hmab foamed.Yuav ua tau zoo li thermoplastics, nrog qib siab ntawm cov tshuaj hla kev muaj kuab, ua rau muaj kev sib tw semi-rigid kaw-cell cov khoom nrog zoo, cov qauv ntawm cell.

Qhov hnyav feem pua ​​​​ntawm vinyl acetate feem ntau txawv ntawm 18% thiab 40%, nrog rau qhov seem yog ethylene.Nyob ntawm cov khoom xyaw hauv cov txheej txheem tsim khoom, cov qib sib txawv ntawm EVA hardness tuaj yeem tau txais.Nws yog ib qho tseem ceeb uas yuav tsum xav txog qib hardness vim EVA tsis rov qab los ntawm nws cov duab tom qab txuas ntxiv compression.Piv nrog rau EVA nyuaj, softer EVA muaj kev puas tsuaj tsawg dua thiab lub neej luv dua, tab sis kev nplij siab dua.

EVA ua npuas ncauj muaj ntau yam khoom zoo:

Moisture Resistant (tsis muaj kua dej)

tshuaj tua kab mob

Lub suab nqus thiab suab rwb thaiv tsev

Kev vibration thiab kev poob siab (kev ntxhov siab tawg tsis kam)

Tsim yooj

Huab cua tsis kam (tsawg kub toughness, UV hluav taws xob tsis kam)

tshav kub-insulating, kub-resistant

tsis pub

damping

Siab zog rau qhov hnyav piv

du nto

Plasticity, ductility, thermoplasticity, thiab lwm yam.

|EVA ntau lawm formula
Cov txheej txheem tsim khoom ntawm EVA ua npuas ncauj muaj xws li pelletizing, blending thiab foaming.EVA resin tau ua tiav rau hauv cov khoom me me, thiab tom qab ntawd hauv ib qho kev faib ua feem, cov khoom no tau tov nrog lwm cov khoom siv ntxiv thiab cov qauv sib txawv los tsim cov ntaub ntawv sib txawv EVA ua npuas ncauj. tus neeg saib xyuas, tus neeg saib xyuas choj, foaming accelerator, lubricant;auxiliary cov ntaub ntawv yog antistatic tus neeg saib xyuas, nplaim retardant, ceev curing tus neeg saib xyuas, colorant, thiab lwm yam. Cov xaiv foaming additive thiab catalyst sib tov txiav txim nws qhov ntom, hardness, xim thiab resilience zog.Cov neeg tsim khoom tam sim no tab tom tsim ultralight, conductive, antistatic, shock resistant, antibacterial, fireproof thiab biodegradable formulations rau tshwj xeeb lub hom phiaj.
