Nkhani - Yankho Lofewa, Lopepuka & Lotanuka la Zinthu Zopangira Thovu la EVA

Yankho la thovu la EVA lofewa, lopepuka komanso lotanuka - SILIKE Si-TPV

Kodi zinthu za thovu za EVA n'chiyani?

Thovu la EVA, kapena thovu la Ethylene-Vinyl Acetate, ndi chinthu chogwiritsidwa ntchito mosiyanasiyana, chopepuka, komanso cholimba chomwe chimagwiritsidwa ntchito m'njira zosiyanasiyana. Ndi thovu lotsekedwa, zomwe zikutanthauza kuti lili ndi matumba ang'onoang'ono, otsekedwa a mpweya omwe amalipangitsa kukhala lofewa, lokongola komanso lolimba. EVA ndi copolymer yopangidwa kuchokera ku ethylene ndi vinyl acetate, ndipo mawonekedwe ake amatha kusinthidwa mwa kusintha chiŵerengero cha zigawozi, zomwe zimapangitsa kuti zigwirizane ndi ntchito zosiyanasiyana.

Mupeza thovu la EVA m'zinthu monga nsapato zofewa (monga nsapato zofewa), zida zamasewera (monga ma padding kapena ma yoga mats), zovala za cosplay (zopangira zida kapena zida), komanso zinthu zolongedza. Ndi lodziwika bwino chifukwa ndi losavuta kudula, kupanga mawonekedwe, ndi guluu, komanso silimalowa madzi, silimayamwa mafunde, komanso lotsika mtengo. Kutengera makulidwe ndi kuchuluka kwake, limatha kuyambira lofewa komanso losinthasintha mpaka lolimba komanso lothandizira.

Kwa zaka zambiri, thovu la Ethylene-Vinyl Acetate (EVA) lakhala likukondedwa kwambiri pa midsoles chifukwa cha kupepuka kwake komanso mtengo wake wokwera. Komabe, pamene zofuna za ogula kuti agwire bwino ntchito, azigwira ntchito molimbika, komanso azikhala olimba zikuchulukirachulukira, zofooka za EVA zikuonekera kwambiri.

Mavuto ndi EVA Thovu ndi Mayankho

N’chifukwa chiyani thovu la EVA nthawi zonse limakhala lopweteka kwambiri kwa mainjiniya?

Kusalimba ndi Kupsinjika Koyipa - Kumabweretsa kutsetsereka kwapakati, kuchepetsa kubwereranso ndi chitonthozo.

Kuchepa kwa kutentha - Kumayambitsa kukula kosasinthasintha komanso magwiridwe antchito osiyanasiyana m'nyengo zosiyanasiyana.

Kukana Kusagwa Kwambiri - Kumachepetsa nthawi yogwiritsira ntchito mankhwala, makamaka pamasewera omwe amakhudza kwambiri.

Kusunga Utoto Wosawoneka Bwino - Kumachepetsa kusinthasintha kwa kapangidwe ka mitundu.

Kubweza Kwambiri - Malipoti a makampani akutsimikizira kuti kubweza nsapato zoposa 60% kumalumikizidwa ndi kuwonongeka kwa pakatikati pa nsapato (NPD Group, 2023).

Zothetsera Zofewa za EVA Thovu

Pofuna kuthetsa mavuto awa, zinthu zingapo zowonjezera zafufuzidwa:

Zinthu Zogwirizanitsa: Zimathandizira kukhazikika kwa kutentha ndi mphamvu zamakina polimbikitsa kulumikizana kwa polymer matrix, zomwe zimapangitsa kuti zikhale zolimba.

Zinthu Zopangira Mpweya: Kuwongolera kufanana kwa kapangidwe ka maselo, kukonza kuchuluka kwa thovu ndi magwiridwe antchito a makina.

Zodzaza (monga silika, calcium carbonate): Zimawonjezera kuuma, mphamvu yokoka, ndi mphamvu zotenthetsera pamene zimachepetsa mtengo wa zinthu.

Mapulasitiki: Amathandizira kusinthasintha ndi kufewa kwa ntchito zomwe zimayendetsedwa ndi chitonthozo.

Zokhazikika: Zimawonjezera kukana kwa UV komanso moyo wautali kuti zigwiritsidwe ntchito panja.

Zodzoladzola/Zowonjezera: Zimathandiza kugwira ntchito bwino (monga, mphamvu zophera tizilombo toyambitsa matenda).

Kusakaniza EVA ndi Ma Polima Ena: Kuti igwire bwino ntchito, EVA nthawi zambiri imasakanizidwa ndi ma rabara kapena ma elastomer a thermoplastic (TPEs), monga thermoplastic polyurethane (TPU) kapena polyolefin elastomers (POE). Izi zimawonjezera mphamvu yokoka, kukana kung'ambika, komanso kupirira mankhwala koma zimadzetsa kusinthana:

POE/TPU: Imawonjezera kusinthasintha koma imachepetsa kugwira ntchito bwino komanso kubwezeretsanso.

OBC (Olefin Block Copolymers): Imakhala yolimba pa kutentha koma imavutika ndi kusinthasintha kwa kutentha kochepa.

Chosinthira cha Silicone Chatsopano cha EVA Foaming

Yankho la Next-Gen la Ultra-Light, Highly Elastic, komanso Eco-Friendly EVA Thovu

Chimodzi mwa zinthu zatsopano kwambiri pakupanga thovu la EVA ndi kuyambitsidwa kwa ichosinthira cha silicone chatsopano, Si-TPV (Elastomer ya Thermoplastic yochokera ku Silicone)Si-TPV ndi elastomer yopangidwa ndi silicone yokhala ndi thermoplastic thermoplastic, yopangidwa pogwiritsa ntchito ukadaulo wapadera wogwirizana womwe umalola rabara ya silicone kufalikira mofanana mu EVA ngati tinthu tating'onoting'ono ta 2-3 micron pansi pa maikulosikopu.

Zipangizo zapaderazi zimaphatikiza mphamvu, kulimba, ndi kukana kukwawa kwa ma elastomer a thermoplastic ndi zinthu zabwino za silicone, kuphatikizapo kufewa, kumva ngati silika, kukana kwa UV, komanso kukana mankhwala. Kuphatikiza apo, Si-TPV imatha kubwezeretsedwanso komanso kugwiritsidwanso ntchito mkati mwa njira zachikhalidwe zopangira, zomwe zimapangitsa kuti ikhale chisankho chosamalira chilengedwe.

Mwa kuphatikiza SILIKE'sChosinthira cha Silicone Thermoplastic Vulcanizate (Si-TPV), Kugwira ntchito kwa thovu la EVA kumasinthidwanso - kumawonjezera kusinthasintha, kulimba, komanso kulimba kwa zinthu zonse pamene kuli koyenera kusunga thermoplastic processing.

Ubwino Waukulu Wogwiritsa NtchitoChosinthira cha Si-TPV mu EVA Foaming:

1. Chitonthozo ndi Magwiridwe Abwino - Zimawonjezera kusinthasintha komanso kulimba kuti ogwiritsa ntchito azikhala ndi chidziwitso chabwino kwambiri.
2. Kukhazikika Kwabwino - Kumapereka kulimba mtima kwabwino komanso kubweza mphamvu.
3. Kukhuta kwa Mtundu Wapamwamba - Kumawonjezera kukongola kwa mawonekedwe ndi kusinthasintha kwa chizindikiro.
4. Kuchepetsa Kuchepa kwa Kutentha - Kumatsimikizira kukula ndi magwiridwe antchito ofanana.
5. Kukana Kuvala Bwino & Kusamva Kutupa - Kumawonjezera nthawi ya moyo wa chinthu, ngakhale pa ntchito zomwe zimakhudzidwa kwambiri.
6. Kukana Kutentha Kwambiri - Kumawonjezera magwiridwe antchito kutentha kwambiri komanso kotsika.
7. Kukhalitsa - Kumawonjezera kulimba, kuchepetsa kutayika kwa zinthu, komanso kulimbikitsa kupanga zinthu zosamalira chilengedwe.

"Si-TPV si yowonjezera chabe—ndi kusintha kwadongosolo kwa EVA Foam Material Science."
Kupatula nsapato zapakati, thovu la EVA lopangidwa ndi Si-TPV limatsegula mwayi watsopano m'mafakitale monga masewera, zosangalatsa, ndi ntchito zakunja.
