Daim ntawv thov ntawm Eva hauv kub yaj cov nplaum
Feb 18, 2025| Kub qhuav adhesives (HMAs) tau siv dav hauv ntau yam kev lag luam vim lawv cov versatility, cov chaw teeb tsa ceev, thiab yooj yim ntawm kev siv. Cov nplaum no yog cov khoom ntawm chav sov thiab ua kua thaum ua kom sov. Ntawm cov sib txawv ntawm cov polymers siv nyob rau hauv kev tsim cov kub yaj cov nplaum,Ethylene-Vinyl acetate (EVA)sawv tawm raws li ib qho ntawm cov ntaub ntawv ua haujlwm feem ntau. EVA cov khoom tshwj xeeb thiab cov khoom siv lub cev ua rau nws muaj ib tus neeg sib tw zoo tshaj plaws rau kev tsim cov khoom siv kub kub yaj, muab cov nplaum sib xyaw rau cov ntawv thov kev lag luam.
Eva yog dab tsi?
Ethylene-Vinyl acetate (EVA)yog copolymer ua los ntawm polymerization ntawm ethylene thiab vinyl acetate. Qhov kev faib ua feem ntawm vinyl acetate nyob rau hauv lub polymer saw tuaj yeem sib txawv, feem ntau yog kwv yees li 10% mus rau 40%, uas muaj ntau cov khoom polymer cov khoom. EVA paub txog nws qhov yooj, tsawg-kub nyuaj, thiab cov nplaum nplaum zoo tshaj plaws. Nws tseem pob tshab, thiab nws cov khoom siv neeg tuaj yeem ua tau yooj yim los ntawm kev kho cov ntsiab lus vinyl acetate cov ntsiab lus.
Nyob rau hauv lub kub yaj cov nplaum kev lag luam, EVA plays ua si lub luag haujlwm tseem ceeb vim tias nws sib npaug ntawm cov adhesion zoo, thiab kub tiv taus. Eva-based kub yaj cov nplaum tau siv nyob rau hauv ntau cov kev siv, los ntawm kev ntim khoom los tsim kho thiab lag luam hauv tsheb.
Cov yam ntxwv ntawm Eva nyob rau hauv kub yaj cov nplaum
Cov haum ntawmYuNyob rau hauv kub yaj cov nplaum yog los ntawm kev sib xyaw ntawm nws lub cev thiab tshuaj lom neeg, xws li:
1. Hloov pauv thiab muag muag
Eva muab kub yaj yaj nrog cov qib siab ntawm kev hloov pauv. Qhov sib ntxiv ntawm vinyl acetate units rau lub ethylene nraub qaum kom tswj tau cov polymer kom muaj qhov ua tau zoo thiab cov khoom siv uas xav tau hauv ntau cov ntawv nplaum. Qhov kev hloov kho no pab tau Eva-based nplaum khaws cia ua lawv cov nyiaj sib cog lus txawm tias muaj kev ntxhov siab thiab deformation, xws li hauv textiles lossis cov khoom siv hluav taws xob.
