Amakuru - Si‑TPV Modifier Yongera Ubudahangarwa bwa TPU ku Myenda Iramba kandi Yoroshye

Elastomer y'Igikoresho cya TPU cyo kwambarwa, Igikoresho cyoroshye nk'uruhu, Ibikoresho by'ikoranabuhanga byo kwambarwa

Ongera Ubudahangarwa bwa TPU: Ibisubizo ku bikoresho byambarwa, insinga, n'ibindi bikoresho byarangiye

Mu isoko ry’ubu rihanganye, polyurethane ya thermoplastic (TPU) ikoreshwa cyane mu bikorwa bikomeye nko mu makoti y’insinga, imikandara yo mu nganda, imikandara yo gufatana, imikandara y’ibikoresho byambarwa, n’ibindi bice bikonje cyane. Ibi bikoresho ntibisaba gusa imiterere ikomeye ya mekanike na elastic ahubwo bisaba no kudashwanyagurika cyane, kandi, mu bihe byinshi, ingano igenwa y’ubushyuhe.

Nyamara abakora ibikoresho byinshi byo mu bwoko bwa OEM n'abakora ibikoresho bivanze basanga na za TPU zo mu rwego rwo hejuru zishobora kwangirika ku buso, kwangirika kw'imitsi, imyitwarire yo gukubita no kunyerera, cyangwa kwangirika vuba mu gihe cyo kuzunguruka.

Ku bahanga mu by’ubwubatsi n’amakipe y’abashushanya, ikibazo cy’ingenzi kiba:Ni gute twakongera uburambe bwa TPU tudahungabanyije uburyo bworoshye, uburyo bwo kureba neza, cyangwa uburyo bworoshye bwo gutunganya ibintu?

Ibisubizo gakondo n'imbogamizi zabyo

Mu myaka yashize, imashini zikora imisemburo zakemuye ibibazo byo kwangirika kwa TPU binyuze mu nzira eshatu z'ingenzi:
• Inyongeramusaruro zisiga amavuta cyangwa zirwanya gucikagurika — urugero, PTFE, molybdenum disulfide, cyangwa sisitemu zishingiye kuri wax zigabanya gucikagurika kw'ubuso ariko zishobora kwimuka cyangwa kugira ingaruka ku buryo ubuso bumeze.
• Udupira tw’ibumba tudashira — urugero, uduce twa ceramic cyangwa amasaro y’ikirahure, bishobora kongera ubushobozi bwo kudashira ariko akenshi byongera ubukana cyangwa bikagabanya ubworoherane.
• Sisitemu zo guhuza ibintu mu buryo buciriritse cyangwa zikora reactive — zigamije gufunga imiterere no kurwanya impinduka ku buso, ariko akenshi zikangiza ubushobozi bwo kongera gukoreshwa cyangwa zigatuma uburyo bwo gutera cyangwa gukoresha inshinge bugorana.

Buri buryo muri ubu bufite inyungu, harimo kwimuka uko igihe kigenda gihita, gukura kw'ubuso, gutakaza ubworoherane, kugabanya ubwiza/gukora ku ruhu, cyangwa ingorane zo gutunganya. Uko porogaramu zigenda ziyongera mu bikoresho byambarwa, insinga, n'imiterere yoroheje yoroshye, hari kwiyongera gukenewe kwa modifier ikomeza ubworoherane, ubwiza bw'ubuso, n'imikorere y'igihe kirekire.

Kumenyekanisha uburyo bushya kandi bunoze bwo kwirinda kwambara imyenda ya TPU

Iterambere riherutse mu gukoresha elastomer zishingiye kuri thermoplastic zikozwe muri thermoplastic(Si‑TPV) itanga igisubizo kirambye ku kurwanya kwangirika kwa TPU, kurenga imbogamizi z'uburyo gakondo.

Iyi Elastomer ya Thermoplastic ishingiye kuri silicone ikozwe hakoreshejwe ikoranabuhanga ryihariye rijyanye n’ibyo ikora kugira ngo ifashe silicone gukwirakwizwa muri TPU ku buryo bungana nk’uduce twa mikoroni 1 ~ 3 munsi ya mikorosikopi. Iyi mashini idasanzwe ihuza imbaraga, gukomera, no kudashwanyagurika kwa elastomer iyo ari yo yose ya thermoplastic hamwe n’imiterere myiza ya silicone: ubworoherane, kumva nk’ubudodo, urumuri rwa UV, no kudashwanyagurika kwa shimi, bishobora kongera gukoreshwa no gukoreshwa mu buryo busanzwe.

Mu kongeramo ingano ikwiye yaSi‑TPV modifier 3100-55AKuri elastomer za thermoplastic polyurethane (TPU), compounders zishobora kugira ubushobozi bwo kurwanya kwangirika, kunoza uburyo bwo guhagarara neza mu gihe cy’ihungabana ry’umubiri, no kurangiza neza mu buryo bworoshye kandi bunoze mu ruhu kandi bugatuma uruhu rukora neza—byose nta mbogamizi zikunze kugaragara mu mavuta, ibikoresho bikomeye, cyangwa uburyo bwo guhuza, nko kwimuka uko igihe kigenda, gukura kw’ubuso, gutakaza ubworoherane, cyangwa kugabanya ubwiza n’imiterere y’uruhu.

Dukurikije ibitekerezo by’abakiriya, isuzuma ry’imbere ryerekana ko ryagabanutseho kwangirika kwa 30-75% ndetse no kwiyongera k’ubudahangarwa bwo kwangirika kwa 2-3× ugereranije n’ibinyabutabire bisanzwe bya TPU mu gihe cy’igeragezwa ry’ikigo—birenze cyane imikorere ya TPU zisanzwe zidashobora kwangirika ku isoko.

Nigute Si‑TPV Ituma TPU Idashira Ingufu?

Uburyo bw'ingenzi bwo guhindura ubuso bwa Si-TPV butuma TPU iramba kandi igakora neza

Hakoreshejwe ikoranabuhanga ryihariye ryo guhuza ibintu hamwe no gukoresha vulcanization idasanzwe, uduce twa silicone rubber (1–3 μm) dukwirakwira mu buryo bumwe muri TPU matrix, bigatuma habaho imiterere yihariye ya "sea-island". Utu duce duto duto dukora uduce duto ku buso bwa TPU, bigatuma habaho imiterere ikoze neza, yoroshye kandi ibereye uruhu.

Iyi miterere ihuza imbaraga za TPU n'ubushobozi bwo gukora bwa silicone rubber, mu gihe igenzura ko uduce twa silicone dukomeza gukwirakwira neza kandi mu buryo buhamye muri matrix.

Uduce twa silicone rubber twakuwemo vulcanized tuba tworoshye, dukora nk'uduce tworoshye twa thermoplastic elastomer, bigabanya ubukana bwa TPU. Ibi bikuraho gukenera plasticizers zo hanze, bikarinda ibibazo byo kwimuka kw'amavuta aho isoko rituruka kandi bigashyigikira ubusugire bw'ubuso igihe kirekire ariko birwanya gufatana kw'ubuso.

Si‑TPV irimo igice kinini cya silicone ifatanye ifite ingufu nke zo hejuru, ibyo bigabanya ingano y’ubushyuhe n’ubukonje bw’ibikoresho bivanze.

Kubera ko umugozi wa silicone uhuza udashobora kugenda muri TPU matrix ku bushyuhe bw'icyumba, ubudahangarwa buturukaho ni buhoraho kandi buhoraho, haba imbere no hanze.

Bitandukanye n'amavuta yo kwimuka nka siloxanes cyangwa waxes, atakaza ubushobozi iyo urwego rwayo rwo kwisiga rumaze kwangirika, Si‑TPV itanga ubushobozi bwo kudashira burundu.

Inama zifatika zo gushyira mu bikorwa: Vanga Si‑TPV muri TPU yawe y'ibanze ku gipimo gisanzwe (urugero, aho utangira gupima ubunini bwa 5–10%. Komeza ukoreshe uburyo bwo gutunganya ibintu nk'uko TPU yawe imeze kugira ngo ushobore gukwirakwira neza..

Niba uri umucuruzi w’ibikoresho byo mu bwoko bwa compounder cyangwa OEM uhura n’ibibazo byo kwangirika kwa TPU—nk’umunaniro wo gukurura insinga, gushwanyagurika no gufatana mu myenda yambarwa, cyangwa ibikoresho byoroshye cyane—Ifite uruhu rwiza kandi ikorakora neza, ikanakoresha ibikoresho byoroshye byo gukoraho Si‑TPVirashobora kugufasha:

• Gutuma habaho ubudahangarwa buhoraho bwo kwangirika

• Bika irangi ryoroshye kandi rifasha uruhu gukoraho rifite ingaruka nziza kandi ridafite ibara ry'uruhu.

• Uburyo bworoshye bwo gutunganya

Suzuma uburyoelastomer za thermoplastic zibungabunga ibidukikije Si‑TPVbishobora kuzamura kuramba no gukora neza kw'ibicuruzwa byawe bya TPU.
