Si-TPV dinamike ya volcanizate ya silopone ya silicone ishingiye kuri elastomer itezimbere tekinoroji ya EVA ifuro

sobanura:

Ethylene vinyl acetate (EVA) ni copolymer itandukanye ikorwa no kuvanga Ethylene na vinyl acetate monomers. Umubare wibintu bya vinyl acetate (VA) muri EVA birashobora gutandukana kuva 2% kugeza kuri 60%, bikemerera guhitamo imitungo yabyo. EVA ifite VA yo hasi, hafi 3 wt%, ikoreshwa muguhindura polyethylene, mugihe ibihimbano bifite VA nyinshi, kuva kuri 5 kugeza kuri 50 wt%, shakisha porogaramu mugukora firime zigabanuka, gupakira ibiryo, ninkweto, nibindi.

Ibisobanuro

Si-TPV dinamike ya volcanizate ya termoplastique silicone ishingiye kuri elastomer nigishya cyoroshye cyoroshye gisukura EVA ifuro. irashobora gukoreshwa nka Modifier EVA ifuro yo kwicara, Modifier Irashobora gukoreshwa nka Modifier EVA ifuro yo kwicara, Modifier EVA ifuro kubikoresho byo gukingira, Modifier EVA ifuro kubikinisho byubwubatsi, Modifier EVA ifuro kubashinzwe kurinda shin, kandi irashobora kandi korohereza kuzamura Eva ifuro ikora inkweto zo kuzamura ikoranabuhanga. Ifite ibyiza byo kugabanya ubushyuhe bwumuriro wa EVA ifuro, kunoza kwihangana no kurwanya abrasion, kunoza ihindagurika ryimiterere yibikoresho, no guteza imbere umwobo wibibyimba kugirango ube umwe kandi wuzuye.

Inyungu z'ingenzi

01

Kunoza ubuhanga bwibikoresho bya EVA

Ugereranije nifu ya talcum cyangwa anti-abrasion, Si-TPV ifite elastique nziza.
02

Kunoza ibara ryuzuye ryibikoresho bya EVA

Amatsinda amwe kuri Si-TPV arashobora gukorana na chromofores irangi, byongera amabara.
03

Kugabanya ubushyuhe bwo kugabanya ibikoresho bya EVA ifuro

Ubworoherane bwa Si-TPV bufasha kurekura impungenge zimbere yibikoresho bya EVA.
04

Kunoza imyambarire irwanya abrasion ibikoresho bya EVA ifuro

Si-TPV irashobora kwitabira reaction yumukozi uhuza, byongera ubucucike.
05

Heterogeneous nucleation

Si-TPV ikwirakwizwa kimwe mubikoresho bya EVA ifuro, bishobora gufasha ingirabuzimafatizo.
06

Mugabanye compression yo guhindura ibikoresho bya EVA ifuro

Si-TPV ifite imikorere myiza yo guhangana nubushyuhe bwo hasi, kandi irashobora icyarimwe kunoza ubushyuhe bwo hejuru bwo hasi no kugabanuka kwubushyuhe bukabije bwibikoresho bya EVA ifuro.

Kuramba

Ikoranabuhanga rigezweho ridafite umusemburo, udafite plastike, nta mavuta yoroshye, kandi nta mpumuro nziza.
Kurengera ibidukikije no kongera gukoreshwa.
Biraboneka muburyo bukurikiza amabwiriza.

Imiyoboro ya EVA

Si-TPV 2250 ikurikirana ifite ibiranga uruhu rurerure rworoshye kuruhu rworoshye gukoraho, kutarwanya neza, nta plastiseri na yoroshye byongeweho, kandi nta mvura igwa nyuma yo kuyikoresha igihe kirekire, cyane cyane ikoreshwa muburyo bwa super light high elastique yangiza ibidukikije EVA ifata ibikoresho.

Guhanga udushya mubikoresho bya EVA Foam (4)

Nyuma yo kongeramo Si-TPV 2250-75A, ubwinshi bwimikorere ya selile ya EVA ifuro igabanuka gato, urukuta rwinshi, kandi Si-TPV ikwirakwizwa murukuta rwinshi, urukuta rwinshi ruba rukabije.

Kugereranya S.i-TPV2250-75A na polyolefin elastomer ingaruka ziyongera muri EVA ifuro

Gusaba

Mugushyiramo modifike ya Si-TPV mubikorwa byawe byo gukora, ubucuruzi bushobora gukora ibikoresho bya EVA ifuro byahawe imbaraga zo kwihangana, kuramba, no guhumurizwa, kugaburira porogaramu zitandukanye, zirimo inkweto, ibicuruzwa by'isuku, imyidagaduro ya siporo, hasi / yoga, n'ibindi.

Bitandukanye na kimwe cya kabiri cya kirisiti, polyethylene, kwinjiza VA monomers bihagarika ishingwa rya kristu mumurongo wa polymer, bigatuma kugabanuka kwa kristu. Mugihe ibirimo VA byiyongera, EVA ihinduka amorphous gahoro gahoro, biganisha kumpinduka mumiterere yumubiri nubukanishi. Mugihe ibipimo nko kurambura kuruhuka, ubushyuhe bwikirahure, nubucucike bwiyongera hamwe nibintu byinshi VA, ibindi nkimbaraga zingana, modulus, ubukana, nubushyuhe bwo kugabanuka bigabanuka. Nubwo, nubwo byongerewe imbaraga, EVA irashobora kwerekana intege nke mumbaraga zamarira, kwambara, hamwe no kwikuramo, cyane cyane mubisabwa bisaba gukomera.

Kugira ngo ukemure izo mbogamizi, EVA ikunze kuvangwa na reberi cyangwa elastomeri ya termoplastique (TPEs), igahindura imbaraga zikaze, kurwanya amarira, kurwanya abrasion, hamwe n’imiti igereranije na EVA yera. Kuvanga EVA hamwe na TPEs nka polymuretike polyurethane (TPU) cyangwa elastomers ya polyolefin (POE) byongera imitekerereze ya viscoelastic kandi byoroshya gutunganya no gutunganya. Byongeye kandi, kugaragara kwa olefin block copolymers (OBC) itanga ibiranga elastomeric hamwe nubushyuhe bwo hejuru. Imiterere yihariye ya OBC, igizwe nibice bigoye hamwe na amorphous yoroshye ibice, itanga imikorere isumba iyindi mikorere, hamwe na compression yashizeho imitungo igereranywa na TPU na TPV.
Nyamara, SILIKE Si-TPV dinamike ya volcanizate ya termoplastique silicone ishingiye kuri elastomer itera imbere ni ikintu cyangiza cyane volcanizate thermoplastique Silicone ishingiye kuri elastomer. Ugereranije nabahindura nka OBC na POE, Ibyingenzi byingenzi byaranze Si-TPV harimo: ● Kunoza ubworoherane bwibikoresho bya EVA ● Kunoza ibara ryuzuye ryibikoresho bya EVA ● Kugabanya ubushyuhe bwo kugabanya ibikoresho bya EVA ifuro ● Kunoza imyuka irwanya abrasion yibikoresho byinshi bya EVA ● Si-TPV
