EVA yog qhov thib plaub loj tshaj plaws ethylene series polymer tom qab HDPE, LDPE thiab LLDPE.Piv nrog rau cov khoom siv tsoos, nws cov nqi qis dua.Ntau tus neeg xav tias EVA ua npuas ncauj yog qhov zoo tshaj plaws ua ke ntawm lub plhaub tawv thiab lub plhaub mos, khaws qhov zoo ntawm cov mos mos thiab tawv ua npuas ncauj thaum tso tseg qhov tsis zoo.Tsis tas li ntawd, qhov yooj yim ntawm cov khoom tsim thiab kev tsim muaj peev xwm kuj yog ib qho tseem ceeb ntawm qee lub ntiaj teb cov tuam txhab ua lag luam thiab cov khoom lag luam tig mus rau EVA ua npuas ncauj thaum cov khoom lag luam zoo, tus nqi qis.

Ntau tshaj qhov hloov tau yooj yim, EVA ua npuas ncauj cov ntaub ntawv saib xyuas peb lub neej txhua hnub thiab kev ua lag luam, thiab tau nthuav dav rau cov neeg siv khoom kawg.Cov khau, tshuaj, cov khoom siv hluav taws xob, cov khoom ua si thiab cov khoom ua si, cov khoom ua si, hauv pem teb / yoga lev, ntim, khoom siv kho mob, cov khoom siv tiv thaiv, cov khoom ua si hauv dej yog qhov xav tau rau cov khoom siv yas ruaj khov, thiab EVA ua npuas ncauj khoom lag luam ntu txuas ntxiv mus rau hauv tshiab kev loj hlob ntawm.
EVA lub cev thiab txhua yam khoom
Cov khoom ntawm EVA copolymer feem ntau yog txiav txim siab los ntawm cov ntsiab lus vinyl acetate thiab cov degree ntawm fluidity.Qhov nce hauv VA cov ntsiab lus nce qhov ceev, pob tshab thiab hloov pauv ntawm cov khoom thaum txo cov ntsiab lus melting thiab hardness.Ethylene-vinyl acetate copolymer (EVA) yog cov khoom siv elastic heev uas tuaj yeem sintered los ua npuas dej zoo ib yam li roj hmab, tab sis muaj zog zoo heev.Nws yog peb zaug hloov pauv ntau dua li qhov ntom ntom polyethylene (LDPE), muaj qhov tensile elongation ntawm 750%, thiab muaj qhov kub siab tshaj plaws ntawm 96 ° C.
Nyob ntawm cov khoom xyaw hauv cov txheej txheem tsim khoom, qhov sib txawv ntawm EVA hardness tuaj yeem ua tiav.Nws yog ib qho tseem ceeb uas yuav tsum tau ua kom muaj qhov nruab nrab ntawm hardness vim tias EVA tsis rov qab los ntawm nws cov duab tom qab compression tas li.Piv nrog rau EVA nyuaj, softer EVA yog tsis tshua muaj resistant rau puas thiab muaj ib tug luv luv lifespan nyob rau hauv lub ib leeg, tab sis yog ntau xis nyob.
Anti-static EVA ua npuas ncauj tsis tsuas yog muaj cov nyhuv anti-static buffering, tab sis kuj muaj lub siab ua haujlwm zoo.
Raws li ESD EVA ua npuas ncauj, muaj ntau ntau hom: engraved ua npuas ncauj thawv, ua npuas ncauj inserts, PP box liners, conductive inserts, thiab lwm yam.,
Rau cov xov tooj ntawm tes, 3G terminals, computers, optoelectronic Cheebtsam, turnover thawv.Muab cov khoom ntawm lub khoos phis tawj sau rau hauv daim npav daim npav ua los ntawm cov paj rwb ua npuas ncauj, thiab sib sau cov kab ua ke los txhim kho kev ua haujlwm.Siv hauv motherboard thiab PCB kev cob qhia kom tsis txhob txiav cov khoom siv hluav taws xob thiab tes thaum siv;LCD tiv thaiv zaub thiab tswj circuits rau LCD vaj huam sib luag ntau lawm kab.
