TPU Intangiriro

Thermoplastique polyurethane (TPU) ni gushonga-gutunganyirizwa hamwe na elastomer ya termoplastique hamwe nigihe kirekire kandi cyoroshye. Ifite ibiranga plastike na reberi bityo ikagaragaza imiterere nko kuramba, guhinduka kimwe nimbaraga zidasanzwe.

TPU, igisekuru gishya cyibikoresho bya thermoplastique. Imiterere yacyo irimo igice gikomeye kandi cyoroshye, cyakozwe na polyole, isocyanate hamwe nu mugozi wagutse ukoresheje reaction.
Ibiranga TPU harimo ibidukikije byangiza ibidukikije, gutunganya byoroshye, imikorere itandukanye, gutunganya ibicuruzwa nibindi. urubanza, kurenza urugero, inkweto, firime, gufatira, umukandara & convoyeur, insinga & kabili nibindi

Ukurikije ubwoko bwa polyol, TPU irashobora kugabanywa mubyiciro bya polyester, icyiciro cya polyether, icyiciro cya polycaprolactone nicyiciro cya polyakarubone nibindi ； ukurikije ubwoko bwa isocyanate, TPU irashobora kugabanywamo TPU nziza na TPU ya alifatique. Ubwoko butandukanye bwa TPU bufite imitungo itandukanye, irashobora gukoreshwa mubikorwa bitandukanye. Urwego rukomeye rwa TPU ni rugari, rutwikiriye 50A-85D.

• Igice cyoroshye (polyether cyangwa polyester): Yubatswe muri polyol na isocyanate itanga ibintu byoroshye kandi biranga imiterere ya TPU.
• Igice gikomeye (aromatic cyangwa aliphatic): Yubatswe uhereye kumurongo wagutse hamwe na isocyanate iha TPU ubukana bwayo nibikorwa byumubiri
  1. TPU ya Aromatic - ishingiye kuri isocyanates nka MDI
  2. Aliphatic TPUs - ishingiye kuri isocyanates nka HMDI, HDI na IPDI

Thermoplastique polyurethanes iroroshye kandi irashobora gushonga. Inyongeramusaruro zirashobora kunoza ihame ryimiterere no kurwanya ubushyuhe, kugabanya guterana amagambo, no kongera ububobere bwumuriro, kurwanya ibihumyo, hamwe nubushyuhe.

TPUs ya Aromatic irakomeye, rusange-intego-isanzwe irwanya kwibasirwa na mikorobe, ihagarara neza kumiti. Ingaruka nziza, ariko, ni impengamiro ya aromatique iteshwa agaciro ninzira yubusa iterwa no guhura nubushyuhe cyangwa urumuri ultraviolet. Uku gutesha agaciro kuganisha ku bicuruzwa no gutakaza ibintu bifatika.

Inyongeramusaruro nka antioxydants, imashanyarazi ya UV, stabilisateur ya amine ikoreshwa mukurinda polyurethanes okiside ya UV iterwa nurumuri bityo bigatuma polyurethanes ya termoplastique ikwiranye nubwinshi bwimikorere ishobora gusaba ubushyuhe bwumuriro na / cyangwa urumuri.

Ku rundi ruhande, Aliphatic TPU, isanzwe ifite urumuri ruhamye kandi irwanya ibara rituruka kuri UV. Birasobanutse kandi neza, bigatuma bakora laminate ikwiye yo gufunga ibirahuri hamwe no kurinda umutekano.
