Si-TPV Modifier: Chinsinsi Chokonzekera Zipangizo Zopangira Thovu za EVA Zopepuka Kwambiri komanso Zosawononga Chilengedwe

fotokozani:

Si-TPV 2250 Series ya SILIKE ndi chosinthira cha elastomer cha thermoplastic chomwe chimasinthiranso ukadaulo wa thovu la mankhwala a EVA, kuonetsetsa kuti thovu limakhala lofanana komanso losasinthasintha. Mwa kuthetsa kusamuka kwa mankhwala ndikupereka chiŵerengero chosinthika cha thovu, Si-TPV imawonjezera magwiridwe antchito opangira, imachepetsa kugwiritsa ntchito mphamvu, komanso imapangitsa kuti thovu lizigwira ntchito bwino.

Chosintha ichi chimalola kupanga thovu la EVA lochepa, lolimba kwambiri lomwe limatha kusweka ndi kutsetsereka bwino, kuchepetsa kutentha, mtundu wofanana, komanso mtengo wapamwamba wa chinthu chomalizidwa. Kusavuta kwake kukonza komanso kugwiritsa ntchito bwino ndalama kumaika thovu ngati njira ina yabwino kwambiri m'malo mwa njira zopopera thovu kwambiri.

Si-TPV 2250 Series ya SILIKE ndi njira yothandiza kwambiri yopangira thovu la EVA, zomwe zimapangitsa kuti nsapato, zida zamasewera, zida zamankhwala, ndi ma CD azikhala omasuka komanso otetezeka.

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, mapilo osambira, zinthu zosangalatsa zamasewera, mphasa zapansi/yoga, zoseweretsa, ma CD, zida zamankhwala, zida zodzitetezera, zinthu zosatsetsereka m'madzi, ndi mapanelo a photovoltaic…
Ngati mukuyang'ana kwambiri njira zothetsera thovu loopsa kwambiri, sitikudziwa ngati ndi lanu, koma ukadaulo uwu wosintha wa Si-TPV wosintha kusintha kwa thovu la mankhwala. Kwa opanga thovu la EVA akhoza kukhala njira ina yopangira zinthu zopepuka komanso zosinthasintha zokhala ndi miyeso yolondola.

Kukulitsa Mafoam a EVA: Kuthetsa Mavuto a Foam a EVA ndi Si-TPV Modifiers

1. Chiyambi cha Zipangizo za thovu la EVA

Zipangizo za thovu la EVA ndi mtundu wa thovu lotsekedwa lomwe limapangidwa kuchokera ku ethylene ndi vinyl acetate copolymers, yokhala ndi polyethylene ndi zinthu zosiyanasiyana zotulutsa thovu ndi ma catalysts omwe amapangidwa popanga. Thovu la EVA lodziwika bwino chifukwa cha cushion yake yabwino kwambiri, kuyamwa kwa shock, komanso kukana madzi, lili ndi kapangidwe kopepuka koma kolimba komwe kamapereka kutentha kwabwino kwambiri. Makhalidwe ake odabwitsa amachititsa thovu la EVA kukhala chinthu chogwiritsidwa ntchito mosiyanasiyana, chomwe chimagwiritsidwa ntchito kwambiri pazinthu zatsiku ndi tsiku komanso ntchito zapadera m'mafakitale osiyanasiyana, monga nsapato zopondera, mphasa zofewa za thovu, ma yoga blocks, ma swimming kickboards, underlay pansi, ndi zina zotero.

2. Kodi Zoletsa za Mafoam Achikhalidwe a EVA Ndi Ziti?

Anthu ambiri amaganiza kuti thovu la EVA ndi kuphatikiza kwabwino kwa chipolopolo cholimba ndi chipolopolo chofewa, Komabe, kugwiritsa ntchito zinthu zopangidwa ndi thovu la EVA kuli kochepa chifukwa cha kukana kwake kukalamba, kukana kusinthasintha, kusinthasintha, komanso kukana kukwawa. Kukwera kwa ETPU m'zaka zaposachedwa komanso kufananiza zitsanzo kumapangitsanso kuti nsapato zopangidwa ndi thovu la EVA zikhale zolimba pang'ono, zopindika kwambiri, zopindika pang'ono, ndi zina zatsopano.

Kuphatikiza apo, Mavuto a Zachilengedwe ndi Zaumoyo pa Kupanga Thovu la EVA.

Zinthu zopangidwa ndi thovu la EVA zomwe zimaperekedwa pamsika pakadali pano zimakonzedwa pogwiritsa ntchito njira ya mankhwala yopangira thovu ndipo zimagwiritsidwa ntchito makamaka pazinthu monga nsapato, mphasa zopukutira pansi, ndi zina zotero zomwe zimakhudzana mwachindunji ndi matupi a anthu. Komabe, zinthu zopangidwa ndi thovu la EVA zomwe zakonzedwa pogwiritsa ntchito njira ndi njira iyi zimakhala ndi mavuto osiyanasiyana oteteza chilengedwe komanso thanzi, makamaka zinthu zovulaza (makamaka formamide) zimalekanitsidwa nthawi zonse ndi mkati mwa chinthucho kwa nthawi yayitali.

3. Mavuto mu Njira Yopangira Thovu la EVA
Njira yopangira thovu la EVA imagwiritsa ntchito mankhwala omwe amagwiritsidwa ntchito popanga thovu la EVA ili ndi mavuto angapo ofunikira:Kusagwirizana kwa Kutentha kwa Kuwonongeka:Kutentha kwa mankhwala otulutsa thovu kumafunika kukhala pamwamba pa kutentha komwe EVA ili pafupi kusungunuka ndi njira yotulutsa thovu ya mankhwala ya EVA, ndipo kutentha kwa mankhwala otulutsa thovu ndi kwakukulu kwambiri ndipo njira yochotsera thovu imakhudza kulinganiza kwa mankhwala, kotero kuti mankhwala otulutsa thovu amakhalabe ochuluka mu matrix ya zinthu pambuyo poti thovu latha, miyeso yoyeretsera EVA yotsika kutentha mu mkhalidwe wosasungunuka ndikuwonjezera zowonjezera zingapo monga mankhwala olumikizirana, stearic acid, choyambitsa cholumikizirana, chothandizira chotulutsa thovu cha mankhwala, pulasitiki ndi zina zotero zimagwiritsidwa ntchito kwambiri mumakampani kuti achepetse mphamvu ya mankhwala otsala a thovu pa magwiridwe antchito a thovu la zinthuzo, koma miyesoyi imapangitsa kuti zinthu zambiri zothandizira ma micromolecular zikhale zosavuta kusuntha mu chinthu chomaliza, ndipo mankhwala othandizira amasamuka nthawi zonse pamwamba pa chinthucho kuchokera mkati pamodzi ndi kugwiritsidwa ntchito kwa nthawi yayitali, kotero kuti matenda a pakhungu kapena kuipitsidwa kwina komwe kumakhudzana ndi chinthucho kumayamba.
Kutulutsa Thovu ndi Kulumikiza Pamodzi:Mu njira yopangira thovu la mankhwala, kuwonongeka kwa mankhwala ophera thovu omwe amatsimikizira khalidwe la thovu ndi kulumikiza kwa mankhwala komwe kumatsimikizira khalidwe la rheology yosungunuka kumachitika nthawi imodzi, ndipo kutentha koyenera kuwonongeka kwa mankhwala ophera thovu si kutentha koyenera kwambiri pa rheology yosungunuka ya maselo ndi kukula.
Njira Yosinthasintha ndi Yosavuta Kutenthetsa:Kugwirizana pakati pa thovu ndi kulumikizana kwa crosslinking ndi kosinthasintha kwambiri komanso kogwirizana ndi kutentha, zomwe zimapangitsa kuti zikhale zovuta kukonza kapangidwe ka selo la thovu. Kuvuta koyendetsa njira izi nthawi imodzi kumapangitsa kuti zikhale zovuta kupanga thovu la EVA lokhazikika komanso labwino kwambiri pogwiritsa ntchito njira zopangira thovu. Mwachidule, kuchuluka kwa zowonjezera ndi zoyambitsa thovu mu njira yopangira thovu la EVA kungakhudze kuchuluka kwake, kuuma kwake, mtundu wake, kulimba kwake, ndi zina zotero.
4. Kafukufuku ndi Zatsopano mu EVA Foam
Pofuna kuthana ndi zofooka za thovu lachikhalidwe la EVA, opanga akhala akufufuza njira zatsopano. Njira imodzi yabwino ndiyo kuphatikiza EVA ndi ma elastomer ena kuti awonjezere magwiridwe antchito. Izi ndizofunikira kwambiri chifukwa makampaniwa akufunafuna zinthu zomwe zimapereka magwiridwe antchito abwino komanso zabwino zachilengedwe.
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.
