Nkhani - Si‑TPV Modifier Imawonjezera Kukana kwa TPU Kuvala Kuti Zikhale Zolimba, Zofewa Zogwira Ntchito

TPU Wearable Device Elastomer, Yofewa Ngati Chikopa cha Wotchi, Zipangizo Zamagetsi Zovalidwa

Kuonjezera Kukana kwa TPU Kuvala: Mayankho a Zovala, Zingwe, ndi Zinthu Zina Zomalizidwa

Mumsika wampikisano wamakono, thermoplastic polyurethane (TPU) imagwiritsidwa ntchito kwambiri pazinthu zovuta monga majekete a chingwe cha ogula, malamba amafakitale, zogwirira ntchito zoyendera, mikanda ya zida zovalidwa, ndi zinthu zina zofewa kwambiri. Zinthu izi sizimangofuna mphamvu zamakina komanso zotanuka zokha komanso kukana kukwawa kwapadera, komanso nthawi zambiri, kuchuluka kwa kukangana komwe kumafotokozedwa.

Komabe ma OEM ambiri ndi ma compounder amapeza kuti ngakhale ma TPU apamwamba amatha kuwonongeka pamwamba, kusokonekera kwa makulidwe, kutsetsereka kwa ndodo, kapena kulephera msanga pamene akupindika mozungulira.

Kwa mainjiniya ndi magulu opanga mapulani, funso lofunika kwambiri ndi lakuti:Kodi tingatani kuti TPU ikhale yolimba popanda kuwononga kufewa, mawonekedwe owoneka bwino, kapena kuthekera kokonza zinthu?

Mayankho Achikhalidwe ndi Zofooka Zawo

Kwa zaka zambiri, opanga zinthu zosiyanasiyana akhala akulimbana ndi mavuto a TPU clocking kudzera m'njira zitatu zazikulu:
• Zowonjezera zopaka mafuta kapena zoletsa kukangana — mwachitsanzo, PTFE, molybdenum disulfide, kapena machitidwe okhala ndi sera omwe amachepetsa kukangana kwa pamwamba koma amatha kusuntha kapena kukhudza momwe pamwamba pake pamawonekera.
• Zodzaza zolimba zosawonongeka — mwachitsanzo, tinthu ta ceramic kapena mikanda yagalasi, zomwe zimatha kulimbitsa kukana kwa kukwawa koma nthawi zambiri zimawonjezera kuuma kapena kuchepetsa kusinthasintha.
• Makina olumikizirana ang'onoang'ono kapena osinthika — cholinga chake ndi kutseka kapangidwe kake ndikuletsa kusinthika kwa pamwamba, koma nthawi zambiri kumalepheretsa kubwezeretsanso kapena kusokoneza njira yopangira jakisoni/kupangira overmolding.

Njira iliyonse mwa izi ili ndi zinthu zina zomwe zingasinthe, kuphatikizapo kusamuka pakapita nthawi, kuphuka kwa pamwamba, kutayika kwa kufewa, kuchepetsa kukongola/kukhudza khungu, kapena mavuto okonza. Pamene ntchito zikuchulukirachulukira m'zovala, zingwe, ndi ma profiles owonda kwambiri, pakufunika kwambiri chosinthira chomwe chimasunga kusinthasintha, khalidwe la pamwamba, komanso magwiridwe antchito a nthawi yayitali.

Kuyambitsa Njira Zatsopano komanso Zogwira Mtima Zopewera Kuvala kwa TPU Compounders

Kupita patsogolo kwaposachedwa kwa ma elastomer okhala ndi thermoplastic thermoplastic omwe amagwiritsidwa ntchito popanga ma elastomer(Si‑TPV) imapereka yankho lokhazikika la kukana kuvala kwa TPU, kugonjetsa zofooka za njira zachikhalidwe.

Thermoplastic Elastomer iyi yopangidwa ndi silicone imapangidwa ndi ukadaulo wapadera wogwirizana kuti ithandize rabara ya silicone kufalikira mu TPU mofanana ngati tinthu ta 1 ~ 3 micron pansi pa maikulosikopu. Zipangizo zapaderazi zimaphatikiza mphamvu, kulimba, ndi kukana kukwawa kwa elastomer iliyonse ya thermoplastic ndi zinthu zabwino za silicone: kufewa, kumva ngati silika, kuwala kwa UV, ndi kukana mankhwala, zomwe zitha kubwezeretsedwanso ndikugwiritsidwanso ntchito popanga zinthu zachikhalidwe.

Mwa kuwonjezera kuchuluka koyenera kwaSi‑TPV modifier 3100-55AKutengera ma elastomer a thermoplastic polyurethane (TPU), ma compounders amatha kukhala ndi kukana kwamphamvu kwa abrasion, kukhazikika bwino kwa makina pansi pa kupsinjika kwa cyclic, komanso kukhudza khungu kofewa kwa nthawi yayitali komanso kogwirizana ndi matte - zonsezi popanda zovuta zomwe zimagwirizanitsidwa ndi mafuta odzola, zodzaza zolimba, kapena machitidwe olumikizirana, monga kusamuka pakapita nthawi, kuphuka kwa pamwamba, kutayika kofewa, kapena kuchepa kwa mawonekedwe okongola komanso kukhudza khungu.

Malinga ndi ndemanga za makasitomala, mayeso amkati akuwonetsa kuchepa kwa kutayika kwa kuvala kwa pafupifupi 30-75% ndi kukana kukanda kwa 2-3× poyerekeza ndi mankhwala wamba a TPU pansi pa mikhalidwe yoyesera ya kampani—kuposa kwambiri magwiridwe antchito a TPU wamba omwe amalimbana ndi kuvala pamsika.

Kodi Si‑TPV Imathandizira Bwanji Kukana Kwamuyaya Kuvala kwa TPU?

Njira Zofunika Zomwe Kusintha kwa Si-TPV Pamwamba Kumathandizira Kulimba kwa TPU ndi Kugwira Ntchito

Pogwiritsa ntchito ukadaulo wapadera wogwirizana ndi vulcanization yosinthasintha, tinthu ta rabara ta silicone (1–3 μm) timafalikira mofanana mkati mwa TPU matrix, ndikupanga mawonekedwe apadera a "nyanja-island". Tinthu tating'onoting'ono tomwe timakhala ndi tinthu tating'onoting'ono timeneti timapanga tinthu tating'onoting'ono pamwamba pa TPU, zomwe zimapangitsa kuti khungu likhale lofewa, losalala, komanso logwirizana ndi khungu.

Kapangidwe kameneka kamaphatikiza mphamvu ya makina ndi kusinthasintha kwa TPU ndi mphamvu zapamwamba zogwira za rabara ya silicone, pomwe zikuwonetsetsa kuti tinthu ta silicone timakhalabe togawika mofanana komanso mokhazikika mkati mwa matrix.

Tinthu ta rabara ta silicone tomwe timapangidwa ndi vulcanized ndi tofewa mwachibadwa, timagwira ntchito ngati magawo ofewa a thermoplastic elastomer, zomwe zimachepetsa kuuma kwa TPU. Izi zimachotsa kufunikira kwa ma plasticizer akunja, kupewa mavuto osamukira kwa mafuta komwe kumachokera komanso kuthandizira kulimba kwa pamwamba kwa nthawi yayitali komanso kupewa kumamatira pamwamba.

Si‑TPV ili ndi gawo lalikulu la rabara ya silicone yolumikizidwa ndi mphamvu yochepa pamwamba, zomwe zimachepetsa kukangana ndi kusweka kwa zinthu zophatikizika.

Popeza rabara ya silicone yolumikizidwa ndi waya imakhala yosasunthika mkati mwa TPU matrix kutentha kwa chipinda, kukana kwa kuwonongeka kumeneku kumakhala kosatha komanso kosasintha, mkati ndi kunja.

Mosiyana ndi mafuta osunthika monga linear siloxanes kapena waxes, omwe amataya mphamvu akangotha mafuta awo, Si‑TPV imapereka mphamvu yolimba yotha kusweka.

Malangizo Othandiza Ogwiritsira Ntchito: Sakanizani Si‑TPV mu TPU yanu yoyambira pa mlingo wolamulidwa (monga, 5–10 wt% nthawi yoyambira). Sungani momwe zinthu zimagwirira ntchito mofanana ndi makina anu a TPU kuti muwonetsetse kuti mwafalikira bwino..

Ngati ndinu wopanga zinthu zophatikiza kapena OEM yomwe ikukumana ndi mavuto okhudzana ndi kuvala kwa TPU—monga kutopa kwa chingwe, kusweka kwa pamwamba ndi kumamatira mu zovala, kapena kugwiritsa ntchito makoma opyapyala kwambiri—Zofewa Zofewa Zokhala ndi Silika Pakhungu kwa Nthawi Yaitali, Zofewa Zogwira Pakhungu ...kungakuthandizeni:

• Imateteza ku kusowa kwa nthawi zonse

• Sungani mawonekedwe ofewa komanso osavuta kugwira pakhungu komanso osawoneka bwino

• Kusavuta kuikonza

Dziwani momwe mungachitirema elastomer a thermoplastic oteteza chilengedwe Si‑TPVikhoza kukweza kulimba ndi magwiridwe antchito a zinthu zanu za TPU.
