Ukadaulo Wokhazikika wa Zinthu Zopangira Foam wa EVA

fotokozani:

Thovu la Ethylene Vinyl Acetate (EVA) lakhala lolimba m'mafakitale osiyanasiyana, kuyambira nsapato mpaka kulongedza, chifukwa cha kusinthasintha kwake, kusinthasintha kwake, komanso kugwiritsa ntchito bwino ndalama. Komabe, kuwononga chilengedwe kwa thovu lachikhalidwe la EVA kwadzetsa nkhawa, zomwe zapangitsa kuti pakhale kufunafuna njira zina zokhazikika.

Tsatanetsatane

Mavuto azachilengedwe akuchulukirachulukira pamene chitukuko cha zachuma chikuchulukirachulukira, ndipo kukwaniritsa chemistry yobiriwira ndi ntchito yofunika kwambiri masiku ano. Ukadaulo wa thovu woopsa kwambiri ndi ukadaulo watsopano wosintha, zinthu zotulutsa thovu zomwe zimagwiritsidwa ntchito muukadaulo wopaka thovu woopsa kwambiri nthawi zambiri zimakhala carbon dioxide (ScCO2) ndi nitrogen woopsa kwambiri (ScN2), zomwe zonsezi zimagwiritsidwa ntchito popanda kuvutitsidwa ndi chilengedwe. Thovu la EVA (Ethylene Vinyl Acetate) ndi pulasitiki yopepuka, yofewa, komanso yolimba yomwe yakhala yolimba m'mafakitale osiyanasiyana chifukwa cha kusinthasintha kwake, kusinthasintha, komanso kugwiritsa ntchito ndalama moyenera.

Ubwino Waukulu

01

Kuonjezera kusinthasintha kwa zinthu zopangira thovu la EVA

Poyerekeza ndi ufa wa talcum kapena mankhwala oletsa kupsa, Si-TPV imakhala ndi kusinthasintha kwabwino.

03

Chepetsani kuchepa kwa kutentha kwa zinthu zopangira thovu la EVA

Kutanuka kwa Si-TPV kumathandiza kumasula kupsinjika kwa mkati mwa thovu la EVA.
04

Kuonjezera kukana kwa thovu la EVA kuti lisawonongeke ndi kuuma kwa zinthu zofewa

Si-TPV imatha kutenga nawo mbali pakuchitapo kanthu kwa wothandizira wolumikizirana, zomwe zimawonjezera kuchuluka kwa kulumikizana.
05

Mitundu yosiyanasiyana ya nucleation

Si-TPV imafalikira mofanana mu thovu la EVA, lomwe lingathandize kupanga maselo.
06

Chepetsani kupsinjika kwa zinthu zopangira thovu la EVA

Si-TPV ili ndi mphamvu yabwino yolimbana ndi kutentha kwambiri komanso kotsika, ndipo nthawi yomweyo imatha kusintha kupsinjika kwa kutentha kwambiri komanso kotsika kwa zinthu za thovu la EVA.

Kukhalitsa Kukhazikika

Ukadaulo wapamwamba wopanda zosungunulira, wopanda pulasitiki, wopanda mafuta ofewetsa, komanso wopanda fungo.
Kuteteza chilengedwe ndi kubwezeretsanso zinthu.
Ikupezeka m'njira zotsatizana ndi malamulo.

Buku Lotsogolera la thovu la EVA

Si-TPV 2250 series ili ndi mawonekedwe a kukhudza kofewa komwe kumagwirizana ndi khungu kwa nthawi yayitali, kukana madontho bwino, kusakhala ndi pulasitiki ndi chofewetsa, komanso kusakhala ndi mvula pambuyo pogwiritsidwa ntchito kwa nthawi yayitali, makamaka kugwiritsidwa ntchito bwino pokonzekera zinthu zopangira thovu la EVA.

Zatsopano mu zipangizo za thovu la EVA (4)

Pambuyo powonjezera Si-TPV 2250-75A, kuchuluka kwa maselo a thovu la EVA kumachepa pang'ono, khoma la thovu limakhuthala, ndipo Si-TPV imafalikira mu khoma la thovu, khoma la thovu limakhala lolimba.

Kuyerekeza kwa Si-TPV2250-75A ndi zotsatira zowonjezera za polyolefin elastomer mu thovu la EVA

Kugwiritsa ntchito

Chosinthira chatsopano cha Si-TPV chobiriwira chomwe chimateteza chilengedwe chomwe chimapatsa mphamvu zinthu zopangira thovu la EVA zomwe zidasinthanso ntchito zosiyanasiyana za tsiku ndi tsiku komanso mafakitale azinthu zamabizinesi monga nsapato, zinthu zaukhondo, zinthu zosangalatsa pamasewera, mphasa zapansi/yoga, zoseweretsa, ma CD, zida zamankhwala, zida zodzitetezera, zinthu zosatsetsereka m'madzi, ndi mapanelo a photovoltaic…

Mwachitsanzo, popanga nsapato, thovu lodziwika bwino la zidendene, zidendene, ndi zidendene za insole ndi zinthu za EVA, zomwe zimathandiza kwambiri pothandizira ndi kulimbitsa mapazi bwino komanso kukonza chitonthozo cha kuvala. Kuphatikiza apo, thovu la EVA limagwiritsidwanso ntchito kwambiri mumakampani opanga ma CD. Chifukwa cha kupepuka kwake komanso kukhala ndi mphamvu zabwino zotetezera komanso kuteteza, thovu la EVA nthawi zambiri limagwiritsidwa ntchito popanga mabokosi, ma cushion opaka, ndi zina zotero, kuteteza mankhwalawa ku kugwedezeka ndi kuwonongeka kwa extrusion panthawi yoyendera. Zachidziwikire, thovu la EVA limagwiritsidwanso ntchito nthawi zambiri popanga zida zamasewera. Mwachitsanzo, mu zida zolimbitsa thupi, ma yoga mat opangidwa ndi thovu la EVA amakhala ndi magwiridwe antchito abwino oletsa kutsetsereka, osalowa madzi komanso omasuka, kupatsa okonda yoga malo ochitira masewera olimbitsa thupi otetezeka komanso omasuka. Ponseponse, thovu la EVA ndi chinthu chogwiritsidwa ntchito mosiyanasiyana. Kapangidwe kake kopepuka, kofewa komanso kolimba kamapangitsa kuti likhale lofunika kwambiri pazinthu za nsapato, ma CD, zida zamasewera ndi zina. Komabe, kukhudzidwa kwa chilengedwe kwa kupanga thovu la EVA kwakhala kukubweretsa nkhawa, zomwe zapangitsa kuti papezeke njira zina zokhazikika.

Kodi mwalowa mu Ukadaulo Wokhazikika wa Zinthu? SILIKE Si-TPV ndi njira yatsopano yosinthira elastomer, Poyerekeza ndi OBC ndi POE, Highlight imachepetsa kupsinjika ndi kutentha kwa zinthu za thovu la EVA.

5, Si-TPV: Chosintha Masewera a Thovu la EVA Lopanda Chilengedwe
SILIKE’s Si-TPV is a groundbreaking thermoplastic silicone-based elastomer that serves as a high-performance modifier for EVA foam. By introducing Si-TPV modifier into EVA foam materials, and leveraging chemical foaming technology, manufacturers can create microporous EVA foams with significant advantages: environmental sustainability, low thermal shrinkage, no chemical migration, and adjustable foaming ratios. This innovation streamlines the production process, resulting in energy savings while improving the mechanical properties of EVA foam. Si-TPV reduces the presence of residual foaming agents, minimizes foam pore sizes, and achieves an ideal balance of low density, high resilience, excellent wear resistance, and reduced thermal shrinkage. Additionally, it enhances the color vibrancy of EVA foams, driving improvements in comfort, aesthetics, durability, and sustainability. Discover the Future of EVA Foam, enhance your products with Si-TPV-modified EVA foams.
