Chii chinonzi thermoplastic polyurethane elasomer?

Polyurethane Elasomer akasiyana-siyana polyurethane zvinhu (mamwe mhando dzinoreva polyurethane foam, polyurethane fiber mumwe chete wePolyurethane Elassomer, vanhu vanowanzoreva nezvayo seTPU (imwe yacho Mhando mbiri huru dzePolyurethane Elasmomers dzinokandwa Polyurethane Elastothane, rakapfupikiswa seCPU, uye rakasanganiswa polyurethane elastomers, rakapfupikiswa seMPU).

TPU rudzi rwiyo rwePolyurethane Elasomer iyo inogona kuve yakapetwa nekudziya nekunyungudika nekunyungudika. Kuenzaniswa neCPU uye MPU, TPU ine zvishoma kana isina kemikari kuyambuka-inobatanidza mune yayo makemikari chimiro. Chaiyo molecular cheni inotsanangurwa, asi pane imwe huwandu hwekuyambuka muviri-kuwanda. Iyi ndiyo iyo thermplastic polyurethane elasomer iyo ine hunhu hwakanyanya muchimiro.

Dhizaini uye kuiswa kweTPU

Thermoplastic polyurethane Elasomer ndeye (AB) block mutsara polymer. Anomiririra polymer polyl (ester kana polyether, molecular uremu hwe1000 ~ 6000) nehuremu hwakanyanya, hunonzi tambo refu; B inomiririra dioli ine 2-12 yakatwasuka carbon maatomu, inonzi pfupi pfupi.

Muchimiro cheTermplastic polyurethane Elasomer, chikamu che chinonzi chakapfava chikamu, icho chine hunhu hwekuchinjika uye kupfava, kugadzira Tpu kuve nekuwedzeredza; Iyo Urethane keteni yakagadzirwa nekuita pakati peC chikamu cheB uye ISOCEANATE inonzi chidimbu chakaoma, icho chine zvivakwa zvakaomarara uye zvakaoma. Nekugadzirisa iyo chiyero che-b hatizi, zvigadzirwa zveTPU nezvivakwa zvakasiyana zvemuviri uye zvemuchina zvinogadzirwa.

Maererano nechimiro chakapfava chemuchimiro, chinogona kukamurwa mumhando yePolyester, yePolyether rudzi, uye rudzi rweButadiene, runezve boka re ester, ether group, kana butene boka. Maererano nechimiro chakaoma chikamu, chinogona kukamurwa muUrethane mhando uye urethane urea mhando, izvo zvine runyararo kubva kuEndylene Glycol Chain Offerders kana diamine Chain In theinters. Iyo yakajairika kugoverwa kwakakamurwa kuva polyester mhando uye polyeter mhando.

Ndezvipi zviratidzo zve tpu synthesis?

(1) polymer diol

Macromolecular Diol nehuremu hweMeloll

Iyo Polymer DiolE yakakodzera yeTPU Elasomer inogona kukamurwa kuita polyester uye polyester inosanganisira polytetrethyle adipic acid glycol (Pba) ε pba; pba; Polyethers vanosanganisira PolyoxyPropylene ether Glycol (PPG), Tetrahydrofuran Polyether Glycol (PTMG), nezvimwe.

(2) diisocyanate

Uremu hwemanyorerwe idiki asi basa rakanakisa, risingabate basa rekubatanidza chikamu chakapfava uye chidimbu chakaomarara, asi zvakare chinowana iyo tpu ine zvinhu zvakasiyana-siyana zvemuviri uye zvakaringana. Iyo Diisocyanates inoshanda kune TPU ndeiyi: Methylene dipherl diisocyanate (MDI), methylene bis (-4-cyclene) (PPDI), PPDI), 1,5-naphthalene diisocyanate (ni), p-p-phenyldimeth diisocyanate (PXDI), nezvimwe.

(3) Chiteni Ext cated

Cheni yacho yakawedzera neyekunyoresera ye100 ~ Maketani anotsigira yakakodzera TPU inosanganisira 1,4-butaneddiol (bdo), 1,4-bis (2-hqee),

Kugadziridzwa kwekushandisa kweTPU sekushongedza mumiririri

Kuti udzikise mari yechigadzirwa uye uwane zvimwe zvekuita, polyurethane Therletastic elassomers inogona kushandiswa seinowanzo shandiswa kusimudzira vamiririri veToughen vakasiyana-siyana uye vakashandurwa rarber zvinhu.

Nekuda kweiyo polarity yakakwira, polyurethane inogona kuenderana ne polar resins kana ruburs, senge cholorinated polyethyle (CPE), iyo inogona kushandiswa kugadzira zvigadzirwa; Kusanganisa neABS inogona kutsiva engineering thermoplastics yekushandisa; Kana ichishandiswa musanganiswa nePolycarbonate (PC), ine zvivakwa zvakadai sekuramba mafuta, kuramba mafuta, uye zvinokanganisa, uye zvinogona kushandiswa kuita miviri yemotokari; Kana zvakasanganiswa ne polyester, kuoma kwayo kunogona kuvandudzwa; Mukuwedzera, inogona kuve inoenderana nePVC, Polyoxymethylene kana PVDC; Polyester polyurethane inogona kuwirirana ne15% nitrile rabber kana 40% nitrile rubber / PVC sanganisa; Polyether polyurethane inogona zvakare kuenderana ne40% nitrile rubber / polyvinyl chloris inonamira; Inogona zvakare kuve yekuenderana neAcressllonitrile Styrene (San) Copolyrers; Inogona kuumba Interpenetrating Network (IPN) Zvivakwa neChinzvimbo Polysiloxanes. Ruzhinji rwevakuru vanotaurwa pamusoroinomisikidza vanonzwisisika vakatogadzirwa zviri pamutemo.

Mumakore achangopfuura, kwave nekuwedzera kutsvagisa kuri kuwedzera kusimudzira kwePom naTpu muChina. Kusanganisa kweTPU uye POM isingavhiringidzi chete kudzikisira kwakakwira uye michina yekushambadzira yeTPU, asi zvakare zvinodziya kuToughens POM. Vamwe vaongorori vakaratidza kuti muTensile Fracture Miedzo, ichienzaniswa nePom Matrix, iyo pom Alloy ine TPU yakashandura kubva kuBrauttle Bracture kune Dractail bracture. Kuwedzerwa kweTPU zvakare endows pom nechimiro memory memory kuita. Iyo Crystalline nzvimbo yePom inoshanda sechiputi chakatemwa chechimiro chekurangarira Alloy, nepo Amorphous nzvimbo yeAmorphous Tpu uye Pom inoshanda sechiputi chakatsaurwa. Kana tembiricha yekudzoreredza iri 165

TPU yakaoma kuwirirana neisiri-polar polymer zvinhu zvakadai sePolyethyle, polypropylene Rubber, Butdiene Rubber, uye haigone kushandiswa kubereka macomposites nekuita kwakanaka. Naizvozvo, nzira dzekurapa dzakadai seplasma, Corona, Wet Chemistry, primer, murazvo kana gasi rekutora rinowanzoshandiswa kune yekupedzisira. Semuenzaniso, iyo American Air Zvigadzirwa uye Commical Computers yeFocs Speeps Kurapa paEltra-Huremu hwe3,Commery, iyo inogona kuvandudza zvakanyanya mwero wegumi, simba uye kupfeka simba uye kupfeka kupokana. Uye F2 / o2 inoshanda gasi kurapwa inogona zvakare kuiswa kune iyo nzira yakarongedzwa pfupi pfupi marita nehurefu hwe6-35mm, iyo inogona kuvandudza kuomarara uye kubviswa kwemabvumirano wezvinyorwa zvemukati.

Ndedzipi nzvimbo dzekushandisa dzeTPU?

Muna 1958, mirelrich chemakemikari kambani (zvino yakatumidzwa zita reLubrizol) rakanyoreswa TPU Brand Esane kekutanga. Kwemakore makumi mana apfuura, pakave nemazita anopfuura makumi maviri emazita akapoterera nyika, uye mhando imwe neimwe ine zvakati wandei zvigadzirwa. Parizvino, iyo huru tpu inogadzira zvinyorwa zviri munyika ndeiyi: Basf, Covestro, Lubrizol, Huntsman Corporation, MCKSSEY, GOLDING, ETRCE.

Semunhu akanakisa elasomer, TPU ane huwandu hwakawanda hwezvigadzirwa zvezvigadzirwa, izvo zvinoshandiswa zvakanyanya mukuda kwemazuva ese, zvinhu zvemitambo, matoyi, zvekushongedza, uye mamwe minda. Pazasi pane mashoma mienzaniso.

① Ngano dzeShangu

TPU inonyanya kushandiswa kune shangu zvinhu nekuda kwekuwedzera kwayo kwakanyanya uye kupfeka kupokana. Tsoka Zvigadzirwa zvine tpu zvakawedzera kugadzikana kupfeka kupfuura ngano dzetsoka, saka dzinoshandiswa zvakanyanya mune yakakwirira-yekupera mbopa zvigadzirwa, kunyanya dzimwe shangu dzemitambo uye shangu dzakasarudzika.

② hoses

Nekuda kwekunyorova kwayo, simba rakanaka, kukanganisa simba, uye kuramba simba rekupisa uye rakaderera rinoshandiswa kuChina.

③ Cable

TPU inopa kupokana nekubvarura, pfeka kupokana, uye kukotama maitiro, neakakwirira uye zvakaderera kupisa kupesana kuve kiyi yekuita cable performance. Saka mumusika weChinese, tambo dzakapfuura dzakadai se tambo dzekutonga uye tambo dzemagetsi Shandisa Tpus kuchengetedza zvigadzirwa zvematanda akaomesesa, uye maficha ari kuwedzera kupararira.

④ Zvishandiso zvekurapa

TPU inzvimbo yakachengeteka, yakagadzikana uye yakakwirira-mhando PVC yakatsiva zvinhu, izvo zvisingazove nePhthalate uye zvimwe zvinhu zvinokuvadza, uye zvichawedzera kune rimwe zvinwiwa muchiremba kana bhegi rekurapa kukonzera mhedzisiro. Uyezve, iyo yakasarudzika yakawedzera giredhi uye jekiseni giredhi tpu inogona kushandiswa nyore nyore nekukanganisa zvishoma mune iripo PVC zvishandiso.

⑤ mota uye dzimwe nzira dzekufambisa

Nekuwedzera uye kuunganidza mativi ese eNylon machira nePolyurethane Elastomer Polyurethane Thermplastic eElasomer akasimbisa negirazi rinogona kushandiswa kuita zvikamu zvemuviri pane mativi ese emota, mikova, mabumipers, anti fronti fundo mitsetse, uye grillals.
