Tpu is polyurethane Thermoplastic eElasomer, inova block block Coplymer yakaumbwa nevadyilicocyanates, polyols, uye ketani-taket. Semukati melasmer yakakwirira, TPU ine huwandu hwakawanda hwekusarudzika zvigadzirwa zviyero uye zvinoshandiswa zvakanyanya mukuda kwezuva nezuva, zvidhori, zvakadai, hosha, tambo, machira ekurapa, etc.
Parizvino, iyo huru tpu gadziri zvinyorwa zvinosanganisira Basf, COvestro, Lubrib, Huntsman, Wanhua Chemical,Linghua Zvishandiso, zvichingoenda zvakadaro. Nekuwedzera uye kuwedzera kwekuwedzera kwemabhizinesi epamba, indasitiri yeTPU iripo inokwikwidza. Nekudaro, mune yakakwirira-yekupedzisira-mugumo munda, iyo ichiripo pane inopararira, iyo zvakare nzvimbo iyo china inoda kuzadzisa breakthers in. Ngatitaurei nezve ramangwana remusika tarisiro yeTPU zvigadzirwa.
1. Supercritical Foaming E-TPU
Muna 2012, Adidas uye basf yakabatana yakagadzira iyo yekumhanyisa shangu Brand Interboost, iyo inoshandisa yakaunzwa TPU (zita rekutengeserana infinerer) sezvinoita zvinhu midsole. Nekuda kwekushandiswa kwePolyether Tpu neakaomarara kuomarara kwe80-85 sekutsanangurwa, zvichienzaniswa neyekupusa
2. Filber yakasimbiswa yakagadziriswa TPU Composite zvinyorwa
TPU ine yakanaka kukanganisa kukanganisa, asi mune zvimwe zvekushandisa, yakakwira elastic modulus uye zvakaoma zvinhu zvinodikanwa. Girazi Fiber Reinforment Shijimendi inzira inowanzo shandiswa kuwedzera iyo elastic modulus yezvinhu. Kuburikidza nekuchinjika, THERMEplastic Inosimudziro ine zvakawanda zvakanakira mudzimu, kupokana kwakasimba, kwakanaka kupokana, kukanganisa kupokana, kugadzikana kwakaderera kwekuwedzera, uye kudzikisira kwakadzika kunogona kuwanikwa.
Basf yakaunza tekinoroji yekugadzirira yakakwira modulus fiberglass yakasimbiswa TPU ichishandisa girazi zvipfupi zvipfupi muhombodo. TPU ine shored d hardness ye83 yaive yakashongedzwa nekuvhenganisa polytetrafluorohlene Glycol (ptmeg, mdi, uye 1,4 Iyi TPU yakavharidzirwa negirazi fiber mune misa ratio ye 52:48 kuti uwane zvinyorwa zvemudziyo neElastic modulus ye 18.3 GPA uye Simba reSimba re 244 Mpa.
Pamusoro pegirazi fiber, pane zvakare mishumo yezvigadzirwa uchishandisa kabhoni fiber tpu, yakadai maCarmo carbon fiber, tpu carposite bhodhi yekusvika 100gpa uye density yakaderera pane simbi.
3. Halogen yemahara murazvo unodzoreredza TPU
Tpu ane simba rakakwirira, kuomarara kwakanyanya, rakanyanya kupfeka kurwisa uye zvimwe zvivakwa, zvichiita kuti ive yakakwana sheath yezvinyorwa zvemawa nemarobhoti. Asi munzvimbo dzekushandisa dzakadai sekushandisa zviteshi, zvakakwirira murazvo kudzoreredzwa kunodiwa. Pane dzimwe nzira mbiri dzekuvandudza murazvo unodzoreredza kuita tpu. Imwe ndeye muripo wekudzokorora kugadziridzwa, izvo zvinosanganisira kuisazve murazvo unodzora zvinhu zvakaita sePoloms kana isocyves Yechipiri inowedzera murazvo unodzora kugadzirisa, izvo zvinosanganisira kushandisa TPU sekutsiva uye kuwedzera murazvo unodzokorora kudzoreredza kusanganisa.
Kugadziriswa kwechiitiko kunogona kuchinja chimiro cheTPU, asi kana huwandu hwemurazvo wekuwedzera simba hwakakura, simba reTPU inoderera, maitiro ekugadzirisa anokanganisa, uye kuwedzera mari shoma haigone kuwana iyo inodiwa murazvo unodzora redare. Parizvino, hapana nzvimbo yekushambadzira inowanikwa yakakwirira inodzora iyo inogona kunyatso sangana nekushandiswa kwezvinhu zvekuchaira.
Vaimbove veBayer Zvekare (zvino Kostron) akambosvitsa phosphorus ine polsol (ihpo) yakavakirwa pane phosphine oxide mune patent. Iyo polyether tpu yakashongedzwa kubva kuIHPO, PTMEG-1000, 4,4 '- MD, uye Bdo inoratidzira yakanakisa murazvo Retardate uye michina. Maitiro ekuwedzera anotsvedza, uye pamusoro pechigadzirwa chakatsiga.
Kuwedzera Halogen-Yemahara Flame parizvino ndiyo inowanzoshandiswa chaizvo nzira yehunyanzvi yekugadzirira Halogen-yemahara murazvo RPU. Kazhinji, phosphorus yakavakirwa, nitrogen yakavakirwa, silicon yakavakirwa, boron based murazvo Retarded adzorerwa kana simbi hydroxides inoshandiswa semurazvo unodzokorora. Nekuda kwekunyepedzera kweTPU, murazvo unodzoreredza kuzadza huwandu hweanopfuura makumi matatu muzana kazhinji inowanzo kudiwa kuti ugadzire murazvo wakagadzikana Nekudaro, iyo huwandu hwemurazvo hwakadzoreredza hwakakura, murazvo unodzoreredzwa zvisina kufanira muTPU Substrate
Basf's Patent inosvitsa murazvo-RedardT tpu tekinoroji, iyo inobatanidza melamine polyphatephate uye phosporolspante yePhosphinic yePhosphini Izvo zvakaonekwa kuti murazvo unodzora basa rakanyanya kuvandudzwa zvakanyanya uchikwaniswa simba rakakwirira.
Kuti uwedzere kusimudzira simba renzvimbo yezvinhu, basf's Patent inosuma nzira yekugadzirira kuyambuka mumiririri masterBatch ine maOsangano. Kuwedzera 2% yerudzi urwu rwekunyorera kune iyo Inosangana neUl94V-0 Plame Retarant Simba reChinyorwa kubva ku30mpa kusvika ku40mpa uchiramba V-0 murazvo unodzora basa.
Kuvandudza kupisa kwekunakidzwa kwekuramba kwemurazvo-kudzoreredza Tpu, iyo patent yeLinghua New Boys Companyzvakare inosvitsa nzira yekushandisa nzvimbo yakafukidzwa simbi hydroxides semurazvo anodzokorora. Kuti uvandudze hydrolysis kuramba murazvo-kudzoreredza Tpu,Linghua New Boys CompanyYakatumirwa kwesimbi carbonate pahwaro hwekuwedzera melamine murazvo unodzoreredzwa mune imwe patent application.
4. Tpu yeiyo automotive pendi yekudzivirira firimu
Firimu remotokari ridziviriro iri firimu rinodzivirira rinozvidzora pendi kubva pamhepo mushure mekuiswa, rinodzivirira mvura, oxidation, inokanda, uye inopa kudzivirira kwenguva refu kweiyo pendi yependi. Basa rayo guru ndeyokuchengetedza iyo yemotokari pendi pamusoro mushure mekuiswa. Iyo pendi yekudzivirira yefirimu inowanzoitika yezvikamu zvitatu, nekuvhara-yekukanda yekuvhara pamusoro, iyo polymer firimu iri pakati, uye yekumanikidza-inomhan'arira-inonamira pasi peganda repasi. Tpu ndeimwe yezviratidzo zvekutanga zvekugadzirira iyo yepakati polymer mafirimu.

Iyo parizvino zvigadzirwa zvakakura ndeye aliphatic tpu yakagadzirirwa kubva kuDicyclohexyl diisocyanate (H12MDI) uye PolycapurpuracCoCCONE DIOL seyakagadzirwa zvinhu. Zvakajairika zveTPU tpu zvinooneka kutendeuka kwero mushure mezuva rimwe chete reUV
POLY (ε - Caprolactone) Tpu ine chekuita zvine mwero zvichienzaniswa nePolyether uye polyester tpu. Kune rimwe divi, zvinogona kuratidzira zvakanakisa kubvaruka kwePolyester Tpu, apo kune rumwe rutivi, zvinoratidzawo kukosha kwekusanzwisisana kwekusarongeka kwekusarongeka kwePolyether Tpu, nokudaro vachishandiswa zvakanyanya mumusika.
Nekuda kwezvakasiyana zvinodiwa zvechigadzirwa-zvinobudirira mushure mekushanda kwemusika, nekuvandudzwa kwekugadzirisa tekinoroji uye zvakare mukana wePolyeth
5. Biobed Tpu
Nzira yakajairika yekugadzirira Bio best tpu ndeyekuisa Bio Shoo
Panyaya yeBio yakavakirwa maOCOCANITATES, kutanga kwa2000, Costvestro, uye vamwe vakaisa mari yakawanda mukutsvagisa kwePDI pdi, uye batch yekutanga yezvigadzirwa zvePDI vakaiswa mumusika muna 2015-2016. Wanhua Chemical yakagadzira 100% Bio bed TPU Zvigadzirwa uchishandisa Bio Yakavakirwa PDI yakagadzirwa kubva kune chibage.
Panyaya yeBio Yakavakirwa Polyols, inosanganisira Bio PolytetraFluorohone (Ptmeg), Bio bed 1,3-bio), Bioed Polyester Polysper, etc.
Parizvino, akawanda tpu Vagadziri vakatanga Bio based Tpu, basa rake rakafanana neyechinyakare petrochemical based tpu. Musiyano mukuru pakati peiyi Bio based tpus iri muchikamu cheBio chakavakirwa mukati, kazhinji kubva pamakumi matatu muzana kusvika ku40%, nevamwe vacho vanotowana yakakwirira mazinga. Kuenzaniswa neyechinyakare petrochemical based tpu, bio best tpu ine zvakanakira sekudzora kabhoni emission Basf, Covestro, Lubrilli, Wanhua Chemical, uyeLinghua ZvishandisoVakatanga Bio yavo Bio TPU Bhurawuti, uye kuderedzwa kabhoni uye kusimudzira ndezvekuti zvakare zvakakosha mafambiro eTPU kuvandudza mune ramangwana.
