Hordhac faahfaahsan

Ethylene-Vinyl Acetate Copolymer, oo inta badan loo soo gaabiyo EVA, waa copolymer laga sameeyay isku dhafka ethylene iyo vinyl acetate monomers. Waa walxo kala duwan oo loo isticmaalo codsiyada kala duwan sababtoo ah sifooyinka la jecel yahay.
Copolymer EVA waxay leedahay meel dhalaalaysa oo hooseeya, dabacsanaan aad u fiican, iyo dheellitir wanaagsan oo adag iyo barti. Waxay u adkaysataa biyaha, shucaaca UV, iyo kiimikooyinka, taas oo ka dhigaysa mid ku habboon codsiyada dibadda. Waxa kale oo ay leedahay adhesion wanaagsan oo ku saabsan substrates badan, taas oo ka dhigaysa mid ku habboon in loo isticmaalo sidii wax-ku-xidhaha ama koollada.
Mid ka mid ah isticmaalka ugu muhiimsan ee EVA waa soo saarista xumbo. Waxaa si weyn loo isticmaalaa in lagu abuuro alaabta barkinta iyo suufka, sida kabaha kabaha, qalabka ciyaaraha, iyo alaabta baakadaha. Xumbooyinka EVA waxay bixiyaan barkin, nuugista naxdinta, iyo raaxada.
Copolymer EVA sidoo kale waxaa loo isticmaalaa soo saarista filimada iyo xaashida. Hufnaanteeda, dabacsanaanteeda, iyo wax qabadkeeda heerkulka hooseeya ayaa ka dhigaya mid ku habboon codsiyada sida daboolka aqalka dhirta lagu koriyo, dhalooyinka la dahaadhay, iyo xidhidhiyeyaasha cadceedda.
Qalabka korantada iyo kuleylka kuleylka ee EVA ayaa ka dhigaya mid faa'iido u leh warshadaha siliga iyo fiilooyinka. Dahaarka EVA iyo walxaha dahaarka ayaa loo isticmaalaa in lagu ilaaliyo oo lagu daboolo fiilooyinka korantada iyo fiilooyinka. Codsiyada kale ee EVA waxaa ka mid ah qaybaha baabuurta, qalabka caafimaadka, alaabta carruurtu ku ciyaarto, iyo alaabta baakadaha.
Guud ahaan, copolymer-ka ethylene-vinyl acetate copolymer waa walxo kala duwan oo leh sifooyin aad u wanaagsan oo ka dhigaya mid ku habboon codsiyo kala duwan.

Codsiga

Ethylene-Vinyl Acetate Copolymer (EVA) waxay leedahay codsiyo kala duwan oo kala duwan oo warshado kala duwan ah sababtoo ah isku darka gaarka ah ee guryaha. Waa kuwan qaar ka mid ah codsiyada caadiga ah ee EVA:
Kabaha:EVA waxaa si aad ah loogu isticmaalaa soo saarista kabaha, gaar ahaan kuwa dhexe iyo kuwa gudaha ku jira. Waxay bixisaa barkin, nuugista naxdinta leh, iyo dabacsanaan, taas oo ka dhigaysa doorasho caan ah oo loogu talagalay kabaha ciyaaraha, kabaha, iyo dacasyada.
BaakadEVA waxaa loo isticmaalaa codsiyada baakadaha maadaama ay bixiso iska caabin aad u wanaagsan iyo dabacsanaan. Waxa caadi ahaan loo isticmaalaa sida xidhmooyinka baakadaha ilaalinta, kiishyada xumbo, iyo dahaarka sanduuqyada iyo weelasha si loo ilaaliyo alaabta jilicsan ama jilicsan inta lagu jiro gaadiidka.
Xabagta iyo shaabadda:Copolymer EVA waxaa loo isticmaalaa sida walxo saldhig u ah soo saarista xabagta iyo shaabada Waxay siisaa ku-xidhka wanaagsan ee substrates kala duwan, sida balaastikada, biraha, iyo alwaax, taasoo ka dhigaysa mid ku habboon codsiyada isku-xidhka.
Xakamaynta fiilada iyo fiilada:EVA waxa loo istcimaalay sida walaxda dahaarka ee fiilooyinka korantada iyo fiilooyinka sababtoo ah sifooyinkeeda korantada ee aadka u wanaagsan. Waxay bixisaa caabbinta qoyaanka, kiimikooyinka, iyo gabowga, hubinta badbaadada iyo isku halaynta hababka korantada.
Filimka iyo xaashida:EVA waxaa caadi ahaan loo isticmaalaa in lagu soo saaro filimo iyo xaashiyo leh dhumucyo kala duwan. Filimadani waxay ka helayaan codsiyada beeraha, daboolada aqalka dhirta lagu koriyo, baakadaha cuntada, baalal cadceedda, iyo muraayadaha la dahaadhay.
Qalabka caafimaadka:EVA waxaa loo isticmaalaa warshadaha daryeelka caafimaadka si ay u soo saarto qalabyada caafimaadka, sida kateetarka, tuubooyinka, iyo daahyada qalliinka. Waxa ay bixisaa isqabqabsi noole, dabacsanaan, iyo habsocod sahlan oo looga baahan yahay codsiyada caafimaadka.
Alaabta lagu ciyaaro iyo waxyaabaha madadaalada:EVA waxaa si weyn loogu isticmaalaa soo saarista alaabada lagu ciyaaro iyo waxyaabaha madadaalada, oo ay ku jiraan xumbo xumbo, aaladaha sabaynta, gogosha yoga, iyo qalabka ciyaaraha xumbo. Waxay siisaa barkin, badbaado, iyo adkeysi codsiyadan.
Qaybaha baabuurta:Alaabta xumbo EVA waxaa lagu shaqeeyaa codsiyada baabuurta ee dahaarka dhawaaqa, qoyaanka gariirka, iyo iska caabinta saamaynta. Waxay kaa caawinaysaa dhimista qaylada, xoojisa raaxada, waxayna bixisaa ilaalinta gudaha baabuurta.
Kuwani waa dhawr tusaale oo ka mid ah codsiyada badan ee EVA. Kala duwanaanshaheeda, dabacsanaanteeda, iyo adkeysigeeda ayaa ka dhigaya wax si weyn looga isticmaalo warshadaha kala duwan.
