Ni ubuhe butumwa bwa poltiplamer?

Polyurethane Elastomer ni ibikoresho bitandukanye bya polyurethane (ubundi bwoko bwerekeza kuri polyurethane, Polyurethane Ubwoko bunini bwa ELULYethane Elandomershane Elanesthane Elanesthane ElaneSomers, amagambo yakubiswe na CPU, kandi avanze Elanesthane Elanesthane, abbreviated nka mpu).

TPU ni ubwoko bwa Polyurethane Elaspespemer ishobora gukubitwa no gushonga na solive. Ugereranije na CPU na Mpu, TPU bifite bike cyangwa nta mbuto bihuza imiterere ya foto yimiti. Urunigi rwarwo rufite umurongo munini, ariko hariho umubare runaka wo guhuza umubiri. Ngiyo polhotplastique Elanesthane iranga cyane mumiterere.

Imiterere no gutondekanya TPU

TheMoreptic Polyurethane Elastomer ni a (ab) guhagarika liner polymer. Igereranya polymer polyol (ester cyangwa polyet, uburemere bwa molekiro ya 1000 ~ 6000) hamwe nuburemere bwimbitse bwa molekilar, bita urunigi rurerure; B igereranya diol irimo urunigi 2-12 igororotse ya karubone, yitwa urunigi rugufi.

Muburyo bwa thermorethane ya polyurethane elastomer, igice a yitwa igice cyoroshye, gifite ibiranga guhinduka no kwiyoroshya, gukora TPU byongerewe; Urunigi rwa Urethane rwabyaye igice cya B na Isocyanate byitwa igice gikomeye, gifite imitungo minini kandi ikomeye. Muguhindura igipimo cyibice bya A na B, ibicuruzwa bya TPU hamwe nuburyo butandukanye bwumubiri na robine.

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.

Nibihe bikoresho fatizo bya synthesis ya TPU?

(1) Polymer Diol

Diol ya Macromolular hamwe nuburemere bwa molekile kuva ku matsinda 500 kugeza kuri 4000 n'amatsinda 50% kugeza kuri 80% muri TPU Elastor, akina uruhare rukomeye mu miterere y'umubiri na shimi ya TPU.

Diol Polymer ibereye TPU Elaspemer irashobora kugabanywamo muri polyester na polyether: Polyester ikubiyemo PolyteRatthylene Adipic Acip Glycol (PHC; Poltethers arimo PolyoxyPropylene ether Glycol (PPG), Tetrahydrofuran Polycol Glycol (PTMG), nibindi

(2) diisocyanate

Uburemere bwa molekila ni gito ariko imikorere ni indashyikirwa, ntabwo igira uruhare gusa yo guhuza igice cyoroshye kandi kikaba cyarushijeho guhuza imitungo myiza yumubiri na robiline zitandukanye. Diisocyanate ikurikizwa kuri TPU ni: Methylene Diphenyl Diphenyl Diisocyanate (MDI), Methylene Bis (-4-cyclenex Diisocyanate (PXDI), nibindi

(3) Urunigi

Urunigi rwumurongo hamwe nuburemere bwa 100 ~ 350, kuba muri diol ntoya, imiterere mito ya molekile, imiterere yumurongo ufunguye kandi nta tsinda risimbuza rifasha cyane kubona uburemere bwa TPU. Urunigi rwagutse rukwiriye TPU rurimo 1,4-Butanediol (BDO), 1,4-HSTCroxyhoxy), PHDMLLLATHenediethanol (PlinyldimbethylGlTlycol (PXG), nibindi

Gukoresha TPU nkumukozi wa Toughening

Kugirango ugabanye ibicuruzwa hanyuma ubone ibikorwa byinyongera, elaurethane yo mu murongo wa Poltinethane ikunze gukoreshwa nkibikoresho bya Toughening kugirango toughening to toughen ibikoresho bitandukanye bya reberplastique no guhindura ibikoresho bya rubber.

Bitewe na polarity yayo ndende, Polyurethane irashobora guhuzwa nisine ya polar cyangwa reberi, nka chloyethylene (cpe), ishobora gukoreshwa mugukora ibicuruzwa byubuvuzi; Kuvuza ab birashobora gusimbuza injeniyeri yo gukoresha; Iyo bikoreshejwe hamwe na Polycarbonate (PC), ifite imitungo nko kurwanya peteroli, kurwanya lisansi, no kurwanya amavuta, no kurwanya ingaruka, kandi birashobora gukoreshwa mugukora imibiri yimodoka; Iyo uhujwe na polyester, ubutoni bwayo burashobora kunozwa; Byongeye kandi, birashobora guhuza neza na PVC, Polyoxymethylene cyangwa PVDC; Polyester polyurethane irashobora guhuza neza na 15% nitrile reberi cyangwa 40% nitrile rubber / pvc bavanze; Polyethethane nayo irashobora guhuza neza na 40% nitrile reberi / polyvinyl chloride kuvanga; Irashobora kandi kubana na Acrylonitrile Styrene (San) copolymers; Irashobora gukora umuyoboro witaruye (IPN) hamwe na Polysiloxanes. Umubare munini wibintu byavuzwe haruguru bivugururwa byavuzwe haruguru bimaze kubyara kumugaragaro.

Mu myaka yashize, habaye ubushakashatsi bwiyongera ku buhungiro bwa pom na TPU mu Bushinwa. Guhuza TPU na pom ntibizamura gusa kurwanya ubushyuhe bukabije hamwe nubutaka bwa TPU, ariko kandi buke cyane pom. Abashakashatsi bamwe bagaragaje ko mu bizamini bya Syinile, ugereranije na Pom Matrix, intoki hamwe na TPU zatumye havamo ivuza ivunika ivunika. Ongeraho TPU nayo irangiza POM hamwe n'imikorere yibuka. Agace ka Crystalline wa Pom ikingira nk'icyiciro cyagenwe cy'ibishyimbo The Boloy, mu gihe akarere ka amorhous TPU na Pom bikora nk'icyiciro gihamye. Iyo ubushyuhe bwo kugarura ari 165 ℃ kandi igihe cyo gukira ni amasegonda 120, igipimo cyo gukira cya alloy kigera kuri 95%, kandi ingaruka zo gukira nibyiza.

TPU biragoye guhuza ibikoresho bidafite polymer nka polyethlene, polyplene propylene reberi, Butadiene Rubber, Butadiene Rubber, kandi imyanda ya rubber cyangwa imyanda Kubwibyo, uburyo bwo kuvura bukabije nka plasma, corona, chiro ya chimiet, primer, flame cyangwa gaze ya flame cyangwa gakondo ikoreshwa kenshi mugihe cyanyuma. Kurugero, ibikomoka ku kirere byabanyamerika hamwe nisosiyete ya chimique yakoraga guhitana gaze ya F2 / O2 ikora uburemere bwa moleclemer ifite uburemere bwa miliyoni 35, kandi yongeraho kunoza imbaraga za miliyoni 35, kandi yongeraho kunoza imbaraga za polekile 3%, kandi yongeraho kunoza imbaraga za Polonular kuri miliyoni 35, kandi yongeraho kunoza imbaraga za Polonular kuri miliyoni 35, kandi yongeraho kunoza imbaraga za Polonular kuri miliyoni 35, kandi yongeraho kunoza imbaraga za miliyoni 3%, kandi yongeraho kunonosora cyane modulus, imbaraga za kanseri no kwambara. Kandi F2 / O2 Gufata gaze yubusa birashobora kandi gukoreshwa kuri fibre ngufi ugereranije nuburebure bwa 6-35mm, bishobora kunoza gukomera no gutongana kubikoresho bihimba.

Ni ubuhe buryo bwo gusaba bwa TPU?

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 tpu nyakabiri nyamukuru ya TPU ku isi ni: Basf, Covestro, Lubrizol, Hunsen Corporation, McKinsey, zahabu, nibindi

Nka Elastomer nziza, TPU ifite ibicuruzwa byinshi byo hasi, bikoreshwa cyane mubihe bya buri munsi, ibicuruzwa bya siporo, ibikinisho, ibikoresho byo gushushanya, nibindi bikoresho. Hasi ni ingero nke.

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.

② 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.

Inkambo

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. Byongeye kandi, urwego rwihariye rwateye imbere no gutera inshinge TPU rushobora gukoreshwa byoroshye hamwe no gukemura ibibazo bike mubikoresho bya PVC buriho.

⑤ Ibinyabiziga nubundi buryo bwo gutwara abantu

Kubyegera no gutwarwa impande zombi za Nylon hamwe na polurethane ya Polurethane, Igitero cyo Kurwana Rafts na Reconnaisances Bitwaje abantu 3-15 bitwaje imikorere ya gilcanike Polhonethane elastomer thermostomer ishimangira hamwe na fibre yikirahure irashobora gukoreshwa mugukora ibice byumubiri nkibice byimodoka ubwayo, uruhu, imigozi, imirongo yamaganye, na grilles.
