Dab tsi yog EVA cov khoom siv: Cov ntsiab lus txhais, siv, thiab vim li cas thiaj xaiv nws?

Hauv kev tsim kho niaj hnub no, Eva tau dhau los ua ib qho ntawm feem ntau ntau yam thiab dav siv cov ntaub ntawv polymer. Los ntawm khau thaiv thiab ntim cov yeeb yaj kiab rau cov kev daws teeb meem thiab cov tshuaj tiv thaiv dej tsis muaj zog, EVA} Vinyl acetate, lub zog, muaj zog, thiab ib puag ncig kev nyab xeeb. Cov ntawv no tshawb nrhiav dab tsi EFA cov khoom siv yog, nws cov khoom tseem ceeb thoob plaws kev lag luam, thiab cov laj thawj nws tau dhau los ua cov qauv zoo rau cov neeg tsim qauv thiab cov tuam ntxhab.

Kev txhais lus thiab muaj pes tsawg leeg ntawm cov khoom EVA

EVA sawv rau ethylene - vinyl acetate copolymer, ib thermoplasuricizing los ntawm copolymerizing etherate (va).

Qhov sib piv ntawm Vinyl acetate - Feem ntau ntawm 5% thiab 40% {3} {} {{} Kev txiav txim siab cov khoom siv, thiab cov khoom nplaum.

Los ntawm molecular storpoint, qhov xwm txheej faib tawm ntawm ethylene thiab vinyl acetate cov qauv sib tsoo thaum tswj cov txheej txheem ntawm cov yas. Qhov siab dua VA cov ntsiab lus, qhov ntau dua nws cov muag muag, pob tshab, thiab kev nruj.

Lub cev, EVA yog lub teeb (ceev >-0.95 g / cm³ yog, thiab resilient, thiab resilient, thiab resilient, thiab resilient, thiab resilient, thiab resilient, thiab rov kho me ntsis. Chemically, nws tsis yog- pa, tsis {{4 4} corrosive, thiab cov kua qaub thiab feem ntau cov kua qaub. Nws zoo tsim nyog tso cai ntau txoj kev xws li kev txhaj tshuaj molding, thiab thermoforming, compression, compression, compression} nplai thiab customized lawm.

 

Cov Khoom Siv Tseem Ceeb ntawm EVA Khoom

Yooj taus thiab elasticity

Eva khaws kev softness thiab resilience tshaj qhov dav kub ntau. Tsis zoo li tsis zoo siab, nws tiv taus kev tawg lossis deformation txawm nyob hauv kev cuam tshuam lossis dabtsi yog khoov.

Kev yuag thiab lub ncoo

Nrog qhov ceev qis thiab zoo kaw - cell tus qauv, eva muaj zoo heev rau kev tiv thaiv, ntim, lossis kev nplij siab- muaj cov ntawv thov.

Dej thiab ya raws tsis kam

Nws cov dej nqus dej qis thiab dej tsis muaj zog ua rau Eva ruaj khov hauv kev nyab xeeb lossis ntub dej. Nws kuj tiv thooj thiab yog ib qho yooj yim los so huv.

Thiab huab cua tsis kam

Eva ua tau zoo nyob rau hauv huab cua txias yam tsis muaj kev nyiag thiab ua kom zoo UV thiab kev kub ntxhov, tsim nyog rau sab nraum zoov lossis ntev {}}} kev siv.

Muaj zog

Raws li lub thermoplastic, eva tuaj yeem kub -}} nias, moulded, txiav, lossis luam tawm. Nws cov khoom ntws ntawm 150-200℃tso cai precision shaking thiab saum npoo kho kom zoo nkauj.

Kev Nyab Xeeb thiab Ib puag ncig Sib Xws

EVA tsis muaj halogen lossis cov tshuab yas thiab tuaj yeem ua raws ROHS, ncav cuag, thiab SGS ib puag ncig cov qauv. Nws hlawv tsis muaj tshuaj lom thiab feem ntau muaj kev nyab xeeb rau cov neeg siv khoom thiab siv.

 

Cov ntawv thov tseem ceeb ntawm EVA cov khoom siv

Eva lub versatility stems los ntawm nws cov ntsiab lus VA adjectable thiab ua kom nws ua kom muaj ntau txoj haujlwm thoob plaws kev lag luam.

Va cov ntsiab lus ntau	Yam ntxwv tseem ceeb	Cov Kev Siv Raug Raug
<5%	Siab meej, muaj zog txhua yam zog	Cov yeeb yaj kiab ua liaj ua teb, ntim cov yeeb yaj kiab, cable rwb thaiv tsev

38–40%	Siab elasticity, cushioning	Nkawm khau soles, foolam pads, tiv thaiv txheej

Hauv cov neeg siv khoom lag luam, Eva siv nyob rau hauv cov khau, khoom ua si, thiab ntaus pob ncaws pob vim nws qhov muag tsis kam, thiab kev nyab xeeb.

Hauv cov teb lag luam, nws ua haujlwm ua ib qho encapsulant nyob rau hauv solar panels, raws li rwb thaiv tsev thiab tsis muaj dej tsaws tsag, thiab ua haujlwm ntawm cov khaub ncaws.

 

Ib qho ntxiv, eva lub foam moulding muaj peev xwm ua rau nws dav siv rau cov ntaub ntim khoom, moulded cov koom haum,Portable cia thawv, thiab cov mob tiv thaiv - daim ntawv thov uas yuav tsum muaj kev tiv thaiv qauv thiab kev tiv thaiv kev tiv thaiv.

 

Piv: Eva vs Lwm cov ntaub ntawv

Nkag siab li cas Eva sib piv nrog lwm cov ntaub ntawv pab txiav txim siab thaum nws yog qhov kev xaiv zoo.

Kev tsom xam:

• Eva muaj qhov sib npaug zoo tshaj plaws ntawm lub teeb, hloov tau yooj yim, thiab kev tiv thaiv.
• Tpu exsels nyob rau hauv high - lub zog, tshuaj ntxuav muag muag tshuaj.
• PVC tshuav tus nqi -} Pib tau zoo tab sis muaj kev txwv nyob rau hauv ib puag ncig kev ua yeeb yam thiab qis- kub hloov.
• Roj hmab muab cov kev elasticity zoo dua tab sis yog qhov hnyav dua thiab tsis tshua siv tau dua tshiab.

 

Vim li cas thiaj xaiv EVA cov khoom siv

Ntau qhov kev ua tau zoo piav qhia txog EVA lub luag haujlwm thoob plaws kev lag luam:

1. High strength-to-weight ratio - provides structural integrity while remaining lightweight.
2. Koj yim lub suab nrov zoo tshaj plaws - Tshem tawm kev poob siab thiab siab.
3. Zoo heev qis - kub kev ua haujlwm {}} tseem tshuav mos thiab yoog raws ib puag ncig txias.
4. Saj zawg zog tsim thiab tsim yooj yim - txhawb nqa cov duab thiab cov ncauj lus kom ntxaws ntxaws.
5. Muaj kev nyab xeeb thiab eclo - Tus phooj ywg {{1} Hais txoj kev nyab xeeb nrog ntiaj teb kev nyab xeeb cov qauv, tsis meej, thiab tsis- lom.
6. Tus nqi -}} Ua tau zoo thiab ruaj khov - muaj lub neej zoo nyob rau hauv nruab nrab nqi.

Cov cwj pwm no ua rau Eva xaiv rau cov tuam ntxhab nrhiav kev tiv thaiv kev tiv thaiv, zoo nkauj, thiab kev ruaj khov hauv lawv cov qauv.

 

Ua thiab customization muaj peev xwm

Eva hloov kho tau rau nws txoj kev tsim khoom.

Nws tuaj yeem yog kub -}}} {{{{2} {{2} {1} Kev hloov pauv kub, lossis kos duab.

Cov tuam txhab tsim khoom tuaj yeem ua kom nruj, tawv ncauj, tuab, thiab sib xyaw ua ke, lossis sib xyaw ua yeeb yam, lossis cov yeeb yaj kiab Tpu los txhim kho kev ua tau zoo lossis tsos.

Xws li cov versatility tso cai rau Eva kom tau ntsib ob qho tib si ua haujlwm thiab kev ua kom zoo nkauj uas yuav tsum muaj nyob rau hauv ntau cov neeg siv khoom thiab cov khoom lag luam muaj kev lag luam.

 

Kev ruaj khov thiab yav tom ntej

Qhov loj hlob ntxiv txog kev ruaj khov yog ua kom nrawm dua tshiab hauv EVA cov ntaub ntawv.

• Bio -} Raws li thiab rov ua dua tshiab EVA cov qauv tsim los txo cov pa roj hmab.
• Nano {{{- Txhim Kho EVA tuaj yeem qhia tus kheej- {{2} {oveant thaj chaw.
• Hybrid Khoom Siv Txuas Ntxiv nrog Eva nrog cov neeg siv roj polymers txuas ntxiv tuaj yeem muab cov kev txhim kho ruaj khov thiab ib puag ncig sib ncig.

Raws li cov khoom siv science evolves, EVA yuav tsum txuas ntxiv mus txuas ntxiv ua haujlwm thiab tsim qauv, txhawb nqa cov khoom lag luam tom ntej, thiab cov khoom lag luam ruaj khov.
