Kusankha choyeneraTPU interlayer ya zinthu zagalasi zopakidwa laminatedChofunika kwambiri ndi kupeza bwino kwambiri m'mbali zitatu izi: magwiridwe antchito achitetezo, mawonekedwe a kuwala, ndi kulimba kwa chilengedwe. Poyerekeza ndi zipangizo zachikhalidwe za PVB (polyvinyl butyral) kapena SGP (ionomer interlayer), TPU imapereka ubwino wapadera chifukwa cha kusinthasintha kwake kwakukulu, kulimba kwake kwakukulu, komanso kusinthasintha kwabwino kwambiri kutentha, zomwe zimapangitsa kuti ikhale yofunika kwambiri pa ntchito zapamwamba zachitetezo, malo opindika, komanso nyengo yovuta.
Ubwino wa Magwiridwe Abwino: Kodi TPU Imatanthauzira Bwanji Galasi Lopaka Mafuta Lapamwamba?
Poyerekeza ndi ma PVB interlayers akuluakulu, TPU imapereka mwayi wokwera kwambiri pazizindikiro zazikulu za magwiridwe antchito.
- Kapangidwe Kabwino Kwambiri ka Makina: TPU ili ndi mphamvu yokoka nthawi 5-10 kuposa PVB, yokhala ndi mphamvu yolimba kwambiri yolimbana ndi kung'ambika ndi kugwedezeka. Kutalika kwake nthawi yopuma kumatha kufika 500%–800%, zomwe zimapangitsa kuti itenge mphamvu yayikulu ya kinetic kudzera mu kusintha kwakukulu ikagwedezeka, zomwe zimathandiza kuti isalowe bwino. Kusinthasintha kwakukulu kumeneku kumapangitsa kuti ikhale chisankho chabwino kwambiri pakugwiritsa ntchito magalasi otetezeka kwambiri monga magalasi oteteza zipolopolo, oteteza kuphulika, komanso oteteza mphepo yamkuntho.
- Kusinthasintha Kwabwino Kwambiri Pakutentha Kochepa: TPU imakhalabe yotanuka ngakhale pa -65°C - mulingo wa magwiridwe antchito womwe PVB ndi zinthu zina sizingagwirizane nawo. Chifukwa chake, ndi yoyenera kwambiri mawindo, makoma a nsalu, ndi ntchito zina m'malo ozizira kwambiri.
- Kumatira kwa Broad Substrate: TPU imamatira bwino kwambiri kuzinthu zosiyanasiyana kuphatikizapo galasi, polycarbonate (PC), ndi acrylic (PMMA), zomwe zimathandiza kupanga mapangidwe opepuka a composite (monga kusintha gawo la galasi ndi PC) kapena kupanga mawonekedwe ozungulira ovuta.
- Kukhazikika kwa Zachilengedwe: Mafilimu a TPU alibe mapulasitiki, kotero savutika ndi kuwonongeka kwa magwiridwe antchito chifukwa cha kusamuka kwa mapulasitiki pakapita nthawi, zomwe zimapangitsa kuti magwiridwe antchito azikhala olimba kwa nthawi yayitali.
Buku Lotsogolera Kusankha Ma Parameter Ofunika
MukasankhaTPUPakati pa zinthu ziwirizi, mfundo zotsatirazi zaukadaulo ziyenera kuperekedwa patsogolo:
| Gulu la Ma Parameter | Chizindikiro Chofunika | Mtengo Wamba / Zofunikira | Malangizo ndi Kufunika kwa Kusankha |
|---|---|---|---|
| Katundu Wowoneka | Kutumiza kwa Kuwala | ≥ 90% | Kuonetsetsa kuti zinthu zikuyenda bwino komanso kuti zinthu zikuyenda bwino. TPU yooneka bwino imatha kufalitsa zinthu zambiri kuposa 90% - zomwe ndizofunikira kwambiri pa ntchito zokongoletsa nyumba. |
| Chifunga | ≤ 1% | Chifunga chotsika chimatanthauza kuwona bwino. TPU yapamwamba imatha kuwongolera chifunga chochepera 1%, kupewa kusokoneza mawonekedwe. | |
| Katundu wa Makina | Kulimba kwamakokedwe | Kawirikawiri > 30 MPa | Mitengo yapamwamba imasonyeza kugwedezeka bwino komanso kukana kubowoka - kofunikira pa ntchito zotetezera monga galasi losalowa zipolopolo. |
| Kutalika pa nthawi yopuma | 400% – 800% | Zinthu zapamwamba zimatanthauza kulimba bwino komanso kuyamwa mphamvu - zimayang'ana kwambiri kuchuluka kwa kutalika kwa ntchito zomwe zimafuna kulimba kwambiri. | |
| Mphamvu Yong'amba | Kawirikawiri > 50 kN/m | Kukana kung'ambika - kumaletsa kuti magalasi asamang'ambike, zomwe zimapangitsa kuti zidutswazo zisamakhale pamalo pake. | |
| Kulimba kwa chilengedwe | Kukana kwachikasu | Kusintha kochepa kwa ΔYI | Aliphatic TPU imateteza bwino kwambiri ku UV - yofunika kwambiri pakugwiritsa ntchito panja kwa nthawi yayitali. |
| Kutentha kwa Utumiki | -40°C mpaka 80°C | TPU imasunga magwiridwe antchito okhazikika pa kutentha kosiyanasiyana, makamaka koyenera malo omwe kutentha kumasinthasintha kwambiri. |
Zochitika Zachizolowezi Zogwiritsira Ntchito & Njira Zosankhira Zinthu
| Chitsanzo cha Ntchito | Chifukwa Chovomerezeka |
|---|---|
| Galasi Losaphulika / Losaphulika | Imagwiritsa ntchito mphamvu ya TPU yolimbana ndi kugwedezeka, kukana kulowa, komanso mphamvu zomwe zimayamwa kuti ikhale yotetezeka kwambiri. |
| Kumanga Mawindo/Makhoma a Makatani m'madera ozizira | TPU imakhalabe yotanuka pa -65°C, yolimbana ndi kuzizira kwambiri komanso kupewa kuuma kwa kutentha kochepa komwe kumachitika m'zida zachikhalidwe. |
| Galasi Lopindika / Looneka Ngati Maonekedwe | Kulimba kwabwino kwa TPU komanso kusinthasintha kwake kwakukulu kumalola kuti igwirizane bwino ndi galasi lopindika popanda kupanga thovu. |
| Kapangidwe Kopepuka Kophatikizana | Amagwiritsa ntchito njira yabwino kwambiri yolumikizira TPU ku galasi ndi PC popanga mapangidwe a "galasi-TPU-PC", zomwe zimapangitsa kuti thupi lizichepa komanso kuti likhalebe lamphamvu. |
Mapeto
Kusankha TPU ya galasi lopaka utoto kwenikweni ndi "kusinthana magwiridwe antchito kuti pakhale chitetezo ndi kulimba". Ndikoyenera kwambiri mapulojekiti okhala ndi miyezo yapamwamba yotetezera chitetezo, kulimba kwa kutentha kochepa, kusinthasintha kwa kapangidwe, komanso kukhazikika kwa nthawi yayitali. Mukasankha, sankhani malinga ndi kuchuluka kwa chitetezo, nyengo, ndi zofunikira za kuwala, kuyang'ana kwambiri mphamvu yokoka, kutalika kwa nthawi yopuma, kutumiza kuwala, chifunga, ndi kukana kwachikasu ngati magawo ofunikira, ndikuchita nawo kulumikizana mozama ndi ogulitsa kuti mupeze mayankho osinthidwa.
Dziwani kuti magawo omwe aperekedwa m'nkhaniyi ndi ofanana ndi makampani. Mitengo yeniyeni imatha kusiyana malinga ndi wopanga komanso mtundu wa chinthucho. Musanamalize kusankha kwanu, ndikulimbikitsidwa kupempha ma Technical Data Sheets (TDS) kuchokera kwa ogulitsa ndikuchita zotsimikizira zenizeni.
ZokhudzaMalingaliro a kampani Yantai Linghua New Material Co., Ltd.
Yantai Linghua New Material Co., Ltd. ili ndi luso lolimba la R&D komanso kupanga zinthu m'munda uno. Kampaniyo idakhazikitsidwa mu 2010, ndipo imayang'ana kwambiri pa R&D ndi kupanga ma thermoplastic polyurethane elastomers (TPU), ndipo tsopano yapanga unyolo wathunthu wamakampani kuphatikiza malonda azinthu zopangira, R&D, ndi kugulitsa zinthu, ndi mphamvu yopangira matani 50,000 pachaka. Kampaniyo yatulutsa cholumikizira cha TPU cha aliphatic makamaka chogwiritsidwa ntchito ndi magalasi opangidwa ndi laminated (kalasi LH73704). Kapangidwe kake ka aliphatic kamapereka kukana kwabwino kwa UV komanso kukana kwachikasu, kukwaniritsa zofunikira zolimba kuti kuwala kukhale kolimba komanso kulimba m'malo omwe amawonekera panja kwa nthawi yayitali, kupereka yankho lodalirika lazinthu zapakhomo pakugwiritsa ntchito magalasi opangidwa ndi laminated apamwamba.
