Si-TPV Soft EVA Foam Modifier: Kusintha kwa EVA Nsapato Payekha thovu

fotokozani:

Foam ya EVA masiku ano ndi chida chodziwika bwino chapakati pa nsapato zamasewera kuti zitenge mphamvu. Chifukwa cha kufewa kwake, kusungunuka komanso kukana kwa mankhwala, zinthu za EVA resin co-foam zimatha kukwanira phazi, ndizopepuka, zopanda fungo komanso zowala. Choncho, amagwiritsidwa ntchito kwambiri pazinthu zokhazokha za nsapato zapakatikati komanso zapamwamba, nsapato zoyendayenda, slippers ndi nsapato. Kukhazikitsidwa kwa Si-TPV yofewa ya foam modifier ya EVA kumapereka mayankho anzeru pankhani ya kukana ma abrasion, kunjenjemera kwamtundu komanso kuchita thovu.

Si-TPV Soft EVA Foam Modifier (yomwe imadziwikanso kuti Silicone For EVA Foaming, Modifier For EVA Foaming Shoes), imapereka njira yopambana ya Soft EVA Foam Modifier Solutions ya EVA thovu lokha la nsapato, ndi Mayankho a Foaming Yapamwamba, pogwiritsa ntchito Chemical Foaming Technology Kwa Eva Wopepuka. Chithovu, bwino bwino abrasion kukana, amachepetsa kutentha shrinkage, kumawonjezera rebound ndi psinjika seti, ndi bwino machulukitsidwe mtundu ndi chifanane. Makhalidwe ake apadera amapangitsa kuti ikhale yabwino popanga ma soles olimba komanso olimba omwe amakwaniritsa zofunikira za nsapato zamakono.

EVA ndiye polima wamkulu wachinayi m'banja la ethylene pambuyo pa HDPE, LDPE ndi LLDPE. Ndiotsika mtengo kwambiri kuposa zida zachikhalidwe. Ambiri amawona thovu la EVA kukhala kuphatikiza koyenera kwa zipolopolo zolimba komanso zofewa, kusunga zabwino za thovu zofewa komanso zolimba ndikutaya kuipa kwake. Kuphatikiza apo, kusinthasintha komwe kumachitika pakupanga ndi kupanga kwazinthuzo ndi chifukwa chachikulu chomwe makampani ena otsogola padziko lonse lapansi amatembenukira ku thovu la EVA akafuna zida zapamwamba komanso zotsika mtengo.

EVA thovu imasamalira moyo wathu watsiku ndi tsiku ndi zochitika zamabizinesi, ndipo yabweretsa zokonda za ogwiritsa ntchito. Ndi kufunikira kwakukulu kwa zinthu zapulasitiki zolimba mu nsapato, mankhwala, mapanelo a photovoltaic, masewera ndi zinthu zosangalatsa, zoseweretsa, zoyala pansi / yoga, kulongedza, zipangizo zamankhwala, zida zotetezera, ndi katundu wa masewera amadzi, gawo la thovu la EVA likupitiriza kuona kukula kwatsopano.

Kutulutsa thovu kwa EVA nthawi zambiri, pali njira zinayi:

Chithovu chachikulu cha mbale yathyathyathya:tsopano mafakitale ang'onoang'ono amagwiritsa ntchito izi, mtengo wamakina ndi zida ndizotsika. Izi zachitika kuchokera mbale, ndiyeno kupyolera ndondomeko kukhomerera, akupera ndi njira zina mu mankhwala.

Chithovu chaching'ono cha mu nkhungu:njirayi imagwiritsidwa ntchito makamaka mu nsapato, nsapato zamasewera kuti apange thovu loyamba la midsole yachiwiri. Malinga ndi chilinganizo chochitira zinthu zabwino granulation, kulemera mu nkhungu lotseguka, thovu ndi maonekedwe ambiri a nsapato. Kuvuta kwa njirayi ndi kufananiza kwa nkhungu ndi chilinganizo, mwinamwake n'zovuta kulamulira kuchulukitsa ndi kuuma nthawi yomweyo.

Jekeseni:ndondomekoyi ndi yaikulu ya m'tsogolo, ndondomeko ikuchitika kunja kwa mankhwala, koma nkhungu molondola ndi apamwamba.

Supercritical thovu:Unyolo wa ma molekyulu a EVA ndi ozungulira, chifukwa chake nthawi zambiri pamafunika kuwonjezera cholumikizira panjira yotulutsa thovu kuti atseke gasi kudzera munjira yolumikizirana. Chifukwa chake, thovu lamphamvu kwambiri la EVA liyenera kuthana ndi vuto la momwe angatsekere gasi.

Kuti apititse patsogolo mawonekedwe a zinthu za thovu la EVA, opanga nthawi zambiri amayambitsa ma elastomers monga EPDM, POE, OBC ndi TPE (mwachitsanzo, SEBS) mu EVA feedstock ndi cholinga chokwaniritsa zolinga zosintha. Mwachitsanzo, kuti mukhale olimba mtima, ndi zina zotero. Si-TPV Soft EVA Foam Modifier imapereka njira ina ya EVA yomwe simangothetsa vuto la magwiridwe antchito, komanso imagwirizana ndi zoyeserera zachilengedwe. Kupanga kwake kwatsopano komanso kupanga kwake kumathandizira kuwonetsetsa kuti mankhwalawa amasunga umphumphu ndi magwiridwe antchito pakapita nthawi, ndikupangitsa kuti ikhale yodalirika komanso yolimba.
Si-TPV Soft EVA Foam Modifier ndi 100% recyclable elastomeric material and Modifier Amachepetsa Kuponderezedwa Kwa Eva Foaming (Modifier For Eva Foaming). Si-TPV imachepetsa kwambiri kuponderezedwa ndi kutsika kwamafuta kwa thovu la EVA poyerekeza ndi OBC ndi POE. Kuphatikiza apo, imathandizira kukhazikika, kufewa, kukana kuterera, komanso kukana abrasion, kuchepetsa abrasion ya DIN kuchokera pa 580 kiyubiki millimita mpaka 179 kiyubiki mamilimita, ndikupangitsa kuti ikhale yabwino kwambiri Flexible Soft Eva Foam Material Solution. Kuphatikiza apo, Si-TPV imapangitsa kuchulukitsitsa kwamitundu yazinthu za thovu za EVA. Kupambana kumeneku kumathandizira opanga kupanga zinthu zowoneka bwino popanda kusokoneza magwiridwe antchito.

Kugwiritsa ntchito

Monga chosinthira chatsopano cha zida za thovu la EVA, Si-TPV imathandizira kupanga zinthu zabwino komanso zolimba zokhudzana ndi thovu la EVA, monga ma midsoles a nsapato zamasewera.

EVA thovu Guide

Mndandanda wa Si-TPV 2250 uli ndi mawonekedwe a kukhudza kofewa kwanthawi yayitali, kukana madontho abwino, palibe plasticizer ndi zofewetsa zomwe zimawonjezeredwa, ndipo palibe mvula ikagwiritsidwa ntchito kwanthawi yayitali, makamaka yogwiritsidwa ntchito moyenera pa Super light high eco-friendly EVA. kupanga thovu kukonzekera zinthu.

Kupanga zatsopano mu EVA Foam materials (4)

Mukawonjezera Si-TPV 2250-75A, kachulukidwe ka cell ya thovu la EVA amachepa pang'ono, khoma la thovu likukulirakulira, ndipo Si-TPV imamwazikana pakhoma la thovu, khoma la thovu limakhala lolimba.

Heterogeneous nucleation

Si-TPV imamwazikana mofanana muzinthu za thovu za EVA, zomwe zingathandize cell nucleation.
06

Chepetsani kupindika kwa zinthu za thovu za EVA

Si-TPV ili ndi magwiridwe antchito abwino kwambiri komanso otsika kutentha, ndipo nthawi imodzi imatha kusintha mawonekedwe apamwamba komanso otsika kutentha kwazinthu zolimba kwambiri za EVA thovu.

Kukhalitsa Kukhazikika

Ukadaulo wapamwamba kwambiri wopanda zosungunulira, wopanda plasticizer, wopanda mafuta ofewetsa, komanso wopanda fungo.
Kuteteza chilengedwe ndi kubwezeretsedwanso.
Amapezeka m'mapangidwe ogwirizana ndi malamulo.
