SILIKE Si-TPV 2250 Series ndi vulcanized thermoplastic silicone-based elastomer yopangidwa kuti ipititse patsogolo zinthu zotulutsa thovu za EVA. Si-TPV 2250 Series imapangidwa pogwiritsa ntchito ukadaulo wapadera womwe umatsimikizira kuti mphira wa silikoni umabalalika mofanana mu EVA ngati 1-3 ma micron particles. Kusintha kwapadera kumeneku kwa zinthu zotulutsa thovu za EVA kumaphatikiza mphamvu, kulimba, ndi kukana kwa ma abrasion a thermoplastic elastomers ndi zinthu zofunika za silikoni, kuphatikiza kufewa, kumva kwa silky, kukana kwa UV, komanso kukana mankhwala. Itha kubwezeretsedwanso ndikugwiritsidwanso ntchito m'njira zachikhalidwe zopangira.
Zida za Si-TPV 2250 Series Eco-Friendly Soft Touch Material zimagwirizana kwambiri ndi ethylene-vinyl acetate (EVA) ndipo zimagwira ntchito ngati chosinthira chatsopano cha silicone cha EVA Foaming, Mayankho owongolera zida za thovu la EVA pakugwiritsa ntchito monga nsapato za nsapato, zinthu zaukhondo, zinthu zosangalatsa zamasewera, mphasa zapansi, ma yoga, ndi zina zambiri.
Poyerekeza ndi OBC ndi POE, Kuunikira kumachepetsa kupsinjika ndi kutentha kwa kutentha kwa zipangizo za thovu la EVA, kumapangitsa kuti kusungunuka ndi kufewetsa kwa thovu la EVA, kumapangitsa kuti anti-slip ndi anti-abrasion kukana, ndipo kuvala kwa DIN kumachepetsedwa kuchokera ku 580 mm3 mpaka 179 mm3 ndikuwongolera machulukitsidwe amtundu wa zida za thovu la EVA.
Zomwe zatsimikizira kukhala zothandiza Flexible Soft Eva Foam Material Solutions.
Si-TPV 2250 Series imakhala ndi kukhudza kofewa kwanthawi yayitali, kukana madontho abwino, ndipo sikufuna kuwonjezera mapulasitiki kapena zofewa. Zimalepheretsanso kugwa kwamvula pambuyo pogwiritsa ntchito nthawi yayitali. Monga chosinthira chofewa chofewa cha Eva chogwirizana kwambiri, ndichoyenera kwambiri pokonzekera zopepuka kwambiri, zotanuka kwambiri, zokomera zachilengedwe za EVA.
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.
Kufananiza kwa Si-TPV2250-75A ndi polyolefin elastomer zowonjezera zowonjezera mu thovu la EVA
Zosintha zatsopano za Si-TPV zobiriwira zobiriwira zomwe zimapatsa mphamvu zinthu zotulutsa thovu za EVA zomwe zidasinthanso moyo watsiku ndi tsiku komanso mabizinesi. monga nsapato, zinthu zaukhondo, mapilo akubafa, zinthu zosangalatsa zamasewera, mphasa zapansi/yoga, zoseweretsa, zonyamula, zida zamankhwala, zida zodzitetezera, zinthu zamadzi zomwe sizimaterera, ndi mapanelo a photovoltaic... pochita thovu, sitikutsimikiza ngati ndi yanu, koma chosinthira cha Si-TPV ichi chomwe chikukonzanso ukadaulo wotulutsa thovu. Kwa opanga thovu a EVA amatha kukhala njira ina yopangira zinthu zopepuka komanso zosinthika zokhala ndi miyeso yolondola.
Kupititsa patsogolo Ma Foam a EVA: Kuthetsa Zovuta za EVA Foam ndi Si-TPV Modifiers
1.Chiyambi cha EVA Foam Materials
Zida za thovu la EVA ndi mtundu wa thovu lotsekeka lomwe limapangidwa kuchokera ku kuphatikiza kwa ethylene ndi ma vinyl acetate copolymers, okhala ndi polyethylene ndi zinthu zosiyanasiyana zotulutsa thovu ndi zopangira zomwe zimayambitsidwa popanga. Wodziwika bwino chifukwa chapamwamba kwambiri, mayamwidwe owopsa, komanso kukana madzi, thovu la EVA lili ndi mawonekedwe opepuka koma olimba omwe amapereka kutentha kwabwino kwambiri. Makhalidwe ake odabwitsa amapangitsa thovu la EVA kukhala chinthu chosunthika, chomwe chimagwiritsidwa ntchito kwambiri pazinthu zonse zatsiku ndi tsiku komanso ntchito zapadera m'mafakitale osiyanasiyana, monga nsapato, mateti ofewa ofewa, zotchinga za yoga, matabwa osambira, pansi, ndi zina zotero.
2.Kodi Zolephera za Traditional EVA Foams ndi ziti?
Anthu ambiri amaganiza kuti EVA thovu zakuthupi ndi kuphatikiza wangwiro chipolopolo cholimba ndi zofewa chipolopolo, Komabe, ntchito EVA thovu zipangizo ndi malire pamlingo wakuti chifukwa cha ukalamba kukana, flexure kukana, elasticity, ndi abrasion kukana. Kukwera kwa ETPU m'zaka zaposachedwa komanso kufananiza kwa zitsanzo kumapangitsanso nsapato za EVA zokhala ndi thovu ziyenera kukhala ndi kuuma pang'ono, kubweza kwapamwamba, kupindika pang'ono, ndi zina zatsopano.
Kuphatikiza apo, Zovuta Zachilengedwe ndi Zaumoyo za EVA Foam Production.
Zinthu zopangidwa ndi thovu za EVA zomwe zimaperekedwa pamsika pano zimakonzedwa ndi njira yopangira thovu ndipo zimagwiritsidwa ntchito kwambiri pazinthu monga nsapato, mateti apansi, ndi zina zotere zomwe zimalumikizana mwachindunji ndi matupi a anthu. Komabe, zinthu zotulutsa thovu za EVA zokonzedwa ndi njirayo ndipo njirayo imakhala ndi chitetezo chambiri komanso zovuta zaumoyo, ndipo makamaka, zinthu zovulaza (makamaka formamide) zimasiyanitsidwa mosalekeza ndi mkati mwazogulitsa kwa nthawi yayitali.
