TPU ni elanesthane thermoplamer ya Polousthane, ari yo yahagaritse umuyoboro wa benshi muri copolymer igizwe na diisocyanates, PolyOl, n'umunyururu. Nkumurimo muremure Elastomer, TPU ifite uburyo butandukanye bwibicuruzwa byoroshye kandi bigakoreshwa cyane mubihe bya buri munsi, ibikoresho bya siporo, ibikoresho byo gushushanya, ibikoresho by'inkweto, amashanyarazi, ibikoresho byo kwivuza, nibindi.
Kugeza ubu, abakora TPU Raw Ibikoresho Bishyize Basf, Covestro, Lubrizol, Huntsman, Imiti ya Wanhua,Linghua Ibikoresho bishya, nibindi. Hamwe nuburyo bwo kwagura ibikorwa byo murugo, inganda za TPU kurubu rurimo guhangana cyane. Ariko, murwego rwo gusaba hejuru, biracyafite ishingiro ryibicuruzwa bitumizwa mu mahanga, ni agace k'Ubushinwa gakeneye kugera ku mihanda muri. Reka tuganire ku isoko ry'ejo hazaza.
1..
Muri 2012, Adidas na Basf bateje imbere ingufu z'isanga ziruka, zikoresha TPU (izina ry'ubucuruzi ryangiza (izina ry'ubucuruzi) nk'ibikoresho byo mu muryango. Kubera ikoreshwa rya PolyEther Tpu ufite inkombe gukomera kwa 80-85 nkuko bigaragaramo, ugereranije na Eva Miaress mu bidukikije Hasi 0 ℃, bitezimbere yambaye neza kandi azwi cyane ku isoko.
2. Fibre ishimangirwa yahinduwe na TPU ibikoresho bigize
TPU ifite ingaruka nziza, ariko muri porogaramu zimwe, molalulus ndende kandi ibikoresho bikomeye birakenewe. Guhindura ibirahuri fibre ni tekinike ikoreshwa kugirango yongere modulus ya elastike. Binyuze mu guhindura, ibikoresho bigizwe ninyungu nyinshi nkibyiza bya elalastique, insulation nziza yo kugarura ibintu, imbaraga nziza zo kwaguka, hamwe no gukomera kwaguka.
Basf yashyizeho ikoranabuhanga ryo gutegura Moderi ndende ya Eberglass yashimangiye TPU ikoresha fibre ngufu yikirahure mumapato yayo. A TPU ifite inkombe d hardness ya 83 yasinye kuvanga polytetraflerouoroiolene glycol (PTMEG, MDO) hamwe na 1,3-Propanedil nkibikoresho fatizo. Iyi TPU yiyongereyeho fibre yikirahure muri gahunda rusange ya 52:48 kugirango ibone ibikoresho bihwanye na molarike ya 18.3 GPA n'imbaraga za kanseri ya 244 MPA.
Usibye ibirahuri, hari kandi amakuru y'ibicuruzwa ukoresheje CARBON CIRBote TPU, nka Costro ya Maezio / TPU akabariro ya TPU, ifite ubuyobozi bwa elastique, bufite moteri ya elastike kuruta ibyuma.
3. Halogen Flame Reddant TPU
TPU ifite imbaraga nyinshi, gukomera, kwambara neza no kurwanya neza hamwe nibindi bintu, bikaba ibintu byiza cyane biranga insinga ninsinga. Ariko mubisabwa muri porogaramu nko kwishyuza sitasiyo, ibidango bya flame birakenewe. Muri rusange hari inzira ebyiri zo kunoza urumuri rwimikorere ya TPU. Imwe ihura na Flame Real Relicardiction, ikubiyemo kumenyekanisha ibikoresho byo gucika intege nka politine cyangwa Iso nyana birimo fosiporusi, azote, nibindi bintu muri Synthesis ya TPU binyuze mu guhuza imiti; Iya kabiri irasuzugura flame idahwitse, ikubiyemo gukoresha TPU nka substrate kandi yongeraho umutuku wa flame kugirango uvange kuvanga.
Guhindura byimazeyo birashobora guhindura imiterere ya TPU, ariko mugihe umubare wa flame flame ari nini, imbaraga za TPU ziragabanuka, imbaraga zo gutunganya, no kongeramo amafaranga make ntishobora kugera kurwego rusabwa. Kugeza ubu, nta gicuruzwa kiboneka mu bucuruzi gitanga umusaruro mwinshi gishobora rwose kuzuza ibyifuzo byo gushyuza sitasiyo.
Uwahoze ari muganga wa Bayer (ubu kosron) yigeze kumenyekanisha fosifori kama irimo polyol (IHPO) ishingiye kuri Folfine oxide muri patenti. PolyEther Tpu synthesised kuva ihpo, PTMEG-1000, 4000, 4,4 '- MDI, na BDO exhbits Shome Shome Redartrant hamwe nubukanishi. Inzira yo gukandamirwa iroroshye, kandi hejuru yibicuruzwa byoroshye.
Ongeraho igihangange cya Halogen-Ubuntu kuri ubu ni inzira ya tekiniki ikunze gukoreshwa mugutezimbere igicucu cya Halogen-Ubusa Tpu. Muri rusange, fosiphorusi ishingiye, azote ishingiye kuri Silicon, ibihangano bya Boron byishyurwa byiyongera cyangwa hydroxides bikoreshwa nka flame redibatants. Bitewe na Flamclent yabereye TPU, ikiruhuko cyo kuzuza umubare urenze 30% bisabwa kugirango bibe igiti gihamye cyaka mugihe cyo gutwika. Ariko, iyo umubare wa flame retardant yongeyeho ni manini, umuhamagaro wa flame utaratatanye muri TPU nta gushidikanya, kandi nacyo bigabanya imitungo ya flame ntabwo ari byiza, bigabanya ibikorwa byayo nkibirori, hamwe na firime, ninsingaza.
Patent ya Basf itangiza tekinoroji ya TPU, ivanga Melamine Polyphosphate na PhoShore irimo acide ya fosphinique nka TPU ibiro bingana na 150KDA. Byagaragaye ko imikorere yo gucika intege yazamuwe cyane mugihe agera ku mbaraga zirenze ndende.
Kugirango ugere kumbaraga za kanseri yibikoresho, patenti ya Basf itangiza uburyo bwo gutegura umukozi wa leta arimo isocyonates. Ongeraho 2% yubu bwoko bwa Masterbation kugeza UL94-0 IBISABWA BIDASANZWE birashobora kongera imbaraga za kanseri yibikoresho kuva kuri 40Ma mugihe cyo kubungabukira V-0.
Kunoza ubushyuhe bwo gusaza Flame-Redartant TPU, patenti yaIbikoresho bishya bya LinghuaKandi utangiza uburyo bwo gukoresha hejuru yicyuma hydroxides nkumuharuro wa flame. Mu rwego rwo kunoza hydrolysis yo kurwanya flame-redirtant TPU,Ibikoresho bishya bya Linghuayatangijwe icyuma gishingiye ku shingiro ryo kongeramo melamine flame mu bundi buryo bwo gusaba patenti.
4. TPU kuri firime yo kurinda automotive
Filime yo kurinda imodoka ni firime yo kurinda igororotse hejuru yikirere nyuma yo kwishyiriraho, irinda imvura ya aside, irinda imvura ya aside, ibimama, kandi itanga uburinzi burambye bwo gusiga irangi. Imikorere nyamukuru ni ukurinda ibisigazwa byimodoka nyuma yo kwishyiriraho. Filime yo kurinda irangi muri rusange igizwe nibice bitatu, hamwe no kwisiga wenyine hejuru, film ya polymer hagati, hamwe nigitutu cya acryct-yunvikana-kubyumva kumurongo wo hasi. TPU nikimwe mubikoresho nyamukuru byo gutegura firime za polymer.
Ibisabwa kuri TPU bikoreshwa muri firime yo kurinda amarangi ni izi zikurikira: Kurwanya Gukuramo, Gufata Ubushyuhe Bwinshi (95MPA, Elongation Imikorere yingenzi ni irwanya ikirere, ikubiyemo kurwanya UV gusaza, gutesha agaciro ubushyuhe, na hydrolysis.
Ibicuruzwa bikuze kuri ubu ni aliphatic tpu byateguwe kuva DICYCHEHELEYLL DIISOCOcyanate (H12MDI) na Diol ya Polycalactone nkibikoresho fatizo. Aromalic isanzwe ya TPU ihinduka umuhondo nyuma yumunsi umwe wa UV irradaire, mugihe Aliphatic TPU ikoreshwa kuri firime yimodoka idashobora gukomeza ibikorwa byumuhondo nta mpinduka zikomeye mubihe bimwe.
Poly (ε - Caprolactone) TPU ifite imikorere iringaniye ugereranije na PolyEther na Polyester TPU. Ku ruhande rumwe, irashobora kwerekana amarira meza yo kurwanya Polyester TPU, mugihe kurundi ruhande, binagaragaza kandi imikorere idahwitse kandi igashyirwa hejuru yimikorere ya PolyEther Tpu, bityo bikoreshwa cyane kumasoko.
Kubera ibisabwa bitandukanye kubicuruzwa byibiciro nyuma yo gutandukanya amasoko, hamwe nuburyo bwo guhinduranya ubuso bwa fortion hamwe nubushobozi bwa polyether cyangwa polyester.
5. TPU
Uburyo busanzwe bwo gutegura TPU ishingiye kuri TPU ishingiye kuri Bio cyangwa inshyirahamwe rishingiye ku isoko, nka Pololiyane ishingiye ku isoko (nka Pololiyane ishingiye ku isoko, mu gihe PolyOls isanzwe.
Ku bijyanye na bio ishingiye ku isobanates, hakiri 2000, Basf, Covestro, n'abandi bashoye imbaraga nyinshi mu bushakashatsi bwa PDI, kandi icyiciro cya mbere cy'ibicuruzwa bya PDI, kandi icyiciro cya mbere cy'ibicuruzwa muri 2015-2016. Imiti ya Wanhua yateye imbere 100% bio bishingiye kuri TPU Ibicuruzwa biranga PDI bishingiye kuri PDI ikozwe mu bubiko bwibigori.
Kubijyanye na bio bishingiye kuri polimali, irimo polyteretraftlerouoIkoherene (PTMEG), bio ishingiye kuri 1,3-Burdanester ishingiye kuri polyOls, nibindi bikorwa muri polyther politiyo, nibindi.
Kugeza ubu, abakora TPU benshi batangije bio bashingiye kuri TPU, imikorere yabo igereranywa na TPU gakondo ya TPU. Itandukaniro nyamukuru riri hagati yibi bio bishingiye kuri tpus biri murwego rwibintu bishingiye kuri bio, muri rusange kuva kuri 30% kugeza kuri 40%, hamwe na bamwe bagera kuri 40%. Ugereranije na peteroli gakondo ya TPU, biremereye TPU ifite ibyiza nko kugabanya ibyuka bihumanya ikirere, birambye kugaruka kubikoresho bibisi, umusaruro wicyatsi, hamwe nububiko bwibikoresho. Basf, Covestro, Lubrizol, Wanhua imiti, naLinghua Ibikoresho bishyaBatangije ibirango bya TPU bishingiye kuri TPU, no kugabanya karubone no kugabanya kandi ni icyerekezo cyingenzi kubijyanye niterambere rya TPU mugihe kizaza.
