Mu 1958, socieme ya Goodrich Climique (ubu yahinduwe Lubrizol) yanditseho TPU BRANDAAN Grand ya mbere. Mu myaka 40 ishize, habaye amazina arenga 20 kwisi yose, kandi buri kirango gifite urukurikirane rwibicuruzwa byinshi. Kugeza ubu, abakora fatizo za TPU barimo basf, Covestro, Lubbol, Hunhaa, itsinda rya shimi, Shanghai Heng'an, Ruihua, imiti ya Xuchuan, n'ibindi.
1, icyiciro cya TPU
Ukurikije imiterere yoroshye yo gutandukanya ibinyagice, irashobora kugabanywamo ubwoko bwa polyester, ubwoko bwa polyether, hamwe nubwoko bwa Butadiene, birimo itsinda rya Ester, itsinda rya ether, cyangwa itsinda rya Butene.
Ukurikije imiterere igoye, irashobora kugabanywamo ubwoko bwa Urethane hamwe na Urethane Urea, bikaba byabonetse bivuye muri Ethylene Glycol Urunigi rwagutse cyangwa diamine. Ibyiciro rusange bigabanyijemo ubwoko bwa polyester no muburyo bwa polyet.
Ukurikije ahari cyangwa kutagira ikibazo cyo guhuza, birashobora kugabanywamo mubice byiza na kimwe cya kabiri.
Ibyambere bifite imiterere yumurongo kandi nta bumwe bwo guhuza. Iyanyuma ikubiyemo amafaranga make yambutse nka acide allophanic ester.
Dukurikije imikoreshereze y'ibikomoka ku bicuruzwa byarangiye, birashobora kugabanywamo ibice bitandukanye (ikintu gitandukanye cy'imashini), imiyoboro itandukanye, filime, ibyapa, amabati, ibisigazwa, ibisigazwa, ibisigazwa, ibisigazwa, ibisigazwa, ibisigazwa, ibisigazwa, ibisigazwa, ibihimbano, ibisigazwa, ibisigazwa, ibisigazwa, ibisigazwa, ibisigazwa, ibisigazwa, ibisigazwa, ibisigazwa, ibisigazwa, ibihimbano, ibisigazwa, ibisigazwa, ibisigazwa, ibisigazwa, ibisigazwa, ibisigazwa, ibisigazwa
2, Synthesis ya TPU
TPU ni iya Polyurethane mubijyanye n'imiterere ya molekelar. None, ni gute byateranije?
Dukurikije gahunda zitandukanye za synthesis, bigabanijwe ahanini muri polymetero yoroheje nigisubizo cyamafaranga.
Muburyo buke, birashobora kandi kugabanywamo uburyo bwibanze hamwe nuburyo bumwe bushingiye ku buntu buhari cyangwa udahari reaction:
Uburyo buhebuje bukubiyemo gufata diisocyanate hamwe na diols ya macromolecular mugihe runaka mbere yo kongeramo urunigi kugirango utange TPU;
Uburyo bumwe bwintambwe ikubiyemo icyarimwe no gukora diols ya macromcolular, diisocyanates, kandi urunigi rwo kwaguka kugirango dushyire TPU.
Igisubizo PolyMerimetion kirimo gushonga kwambere muri soteve, hanyuma ongeraho diols ya macromcolular, hanyuma yongeraho igihe runaka, hanyuma wongere urunikiro rwongereye urunigi kugirango tubyare TPU.
Ubwoko bwa TPU bworoshye, uburemere bwa moleki, ibinyabuzima bigoye cyangwa byoroshye, hamwe na leta ya TPU irashobora kugira ingaruka ku buke bwa TPU, hamwe n'ubucucike bugereranywa n'abandi bashibe na plastike.
Kuri ubukana bumwe, ubucucike bwa polythereir ubwoko bwa TPU iri munsi yubwato bwa polyester TPU.
3, gutunganya TPU
TPU ibice bisaba inzira zitandukanye kugirango ukore ibicuruzwa byanyuma, cyane cyane ukoresheje uburyo bwo gushonga nubutumwa bwo gutunganya TPU.
Gutunganya gusangira ni inzira isanzwe ikoreshwa munganda za plastiki, nko kuvanga, kuzunguruka, gukandagira, guhubuka, no kubumba;
Solution processing is the process of preparing a solution by dissolving particles in a solvent or directly polymerizing them in a solvent, and then coating, spinning, and so on.
Ibicuruzwa byanyuma byakozwe muri TPU mubisanzwe ntibisaba gutera inkunga impungenge zinyuranya, zikaba zishobora kugabanya ibizunguruka no gutunganya imyanda.
4, imikorere ya TPU
TPU ifite modulus ndende, imbaraga nyinshi, kurambura hejuru no kwikuramo, kwambara neza, kwambara neza, kurwanya peteroli, kurwanya ubushyuhe buke, no kurwanya ubushyuhe.
Imbaraga zirenze ndende, kurambura hejuru, hamwe nigihe gito cyo gutunganya igipimo cyimiterere burundu na byose byingenzi bya TPU.
XIAOU igurisha cyane cyane kumiterere ya TPU iva mubintu bidashidikanywaho no kwikuramo, kwihangana, gukomera, nibindi.
Imbaraga ndende zo hejuru no kurambura hejuru
TPU ifite imbaraga nziza cyane no kwihirika. Duhereye ku makuru mu gishushanyo gikurikira, turashobora kubona ko imbaraga za tensile no kurambura ubwoko bwa polyether tpu biruta byinshi kuruta ibya polyvinyle ya plastiki na reberi.
Byongeye kandi, TPU irashobora kuba yujuje ibisabwa inganda zibiribwa hamwe na bike cyangwa ntanyongera byongeweho mugihe cyo gutunganya, nabyo biragoye kubindi bikoresho nka PVC na reberi kugirango ubigereho.
Kwihangana nukumva cyane ubushyuhe
Kwihangana kwa TPU bivuga uburyo bwahise butwara imiterere yumwimerere nyuma yo guhangayikishwa no gucika intege, bigaragazwa nkimbaraga zo kugarura, bikaba ikigereranyo cyo gusubira inyuma, kikaba ikigereranyo cyo gusubira inyuma, kikaba ikigereranyo cyo gusubira inyuma kumurimo usabwa gukora. Ni umurimo wa modulus ifite imbaraga hamwe niterambere ryimbere ryumubiri kandi numva cyane ubushyuhe.
Gusubiramo bigabanuka bigabanuka k'ubushyuhe kugeza ubushyuhe runaka, kandi uburyo bwongeye kwiyongera vuba. Ubu bushyuhe nubushyuhe bwa Crystallisation yiki gice cyoroshye, kigenwa nuburyo bwa Diorl ya Macromolecular. Ubwoko bwa polyether TPU iri munsi ya polyester ubwoko TPU. Ku bushyuhe munsi yubushyuhe bwa Crystallisation, Elastomer irakomera cyane kandi itakaza imbaraga zayo. Kubwibyo, kwihangana birasa nu rebound kuva hejuru yicyuma gikomeye.
Imvune ikomeye ni inkombe A60-D80
Gukomera ni ikimenyetso cyubushobozi bwibintu bwo kurwanya imico, gutsinda, no gushushanya.
Gukomera kwa TPU mubisanzwe bipimwa hakoreshejwe inkombe a no ku nkombe d testers dralnesters, hamwe na skore yakoreshejwe kugirango yoroshye tpus kandi igakoreshwa cyane.
Gukomera kwa TPU birashobora guhinduka muguhindura ibipimo byoroshye kandi bikomeye. Kubwibyo, TPU ifite ubunini bukomeye, kuva ku nkombe A60-D80, umaze gukomera kwa reberi na plastike, kandi bifite aho bikabije.
Nkuko bikomeye bihinduka, ibintu bimwe bya TPU birashobora guhinduka. Kurugero, kongera gukomera kwa TPU bizavamo impinduka zikorwa nka motile imbaraga zidashira, kongera imihangayiko ikomeye kandi yo kwiyongera.
5, gusaba TPU
Nka Elastomer nziza, TPU ifite icyerekezo kinini cyibicuruzwa byamafaranga kandi ikoreshwa cyane mubihe bya buri munsi, ibicuruzwa bya siporo, ibikinisho, ibikoresho byo gushushanya, nibindi bikoresho.
Ibikoresho by'inkweto
TPU ikoreshwa cyane cyane kubikoresho byonsa kuberako byoroshye kandi yambara. Ibicuruzwa bikubiyemo TPU biroroshye cyane kwambara kuruta ibicuruzwa bisanzwe, bityo birakoreshwa cyane mubicuruzwa byikinyondiro cyinshi, cyane cyane inkweto zimwe na zimwe za siporo ninkweto zisanzwe.
hose
Kubera ubwitonzi bwayo, imbaraga nziza, imbaraga, no kurwanya ubushyuhe bwo hejuru no hasi bikoreshwa cyane mu Bushinwa nk'indege, tank, imodoka, ibikoresho bya moto.
umugozi
TPU itanga amaturo yo kurwanya amarira, yambara kurwanya, kandi yunamye ibiranga, hamwe no kurwanya ubushyuhe bwo hejuru kandi buke ni urufunguzo rwimikorere ya kabili. Mu isoko ryibishinwa rero, insinga zateye imbere nko kugenzura imiyoboro yubugenzuzi nubutaka bwo gukoresha Tpus kugirango urinde ibikoresho byimigozi byimigozi igoye, kandi ibyifuzo byabo biragenda byiyongera.
Ibikoresho byo kwa muganga
TPU ni ibintu byiza, bihamye bya PVC nziza cyane ya PVC, itazaba irimo phthalate nibindi bintu byangiza, kandi bizamuka mumaraso cyangwa izindi mazi muri catheter yubuvuzi cyangwa umufuka wubuvuzi kugirango bitera ingaruka. Ni kandi urwego rwihariye rwateye imbere no gutera inshinge TPU.
film
Filime ya TPU ni firime yoroheje ikozwe muri TPU Ibikoresho bya Granular binyuze muburyo budasanzwe nko kuzunguruka, guta, kuvuza, no guhisha. Kubera imbaraga zayo nyinshi, zambara ihohoterwa, elastique nziza, hamwe na firime za TPU zikoreshwa cyane mu nganda, ibikoresho by'inkweto, imyenda, imiti, kwivuza, ubuvuzi, n'izindi nzego.
