TPU (Polyurethane Elastomer)

TPU (TheRoplastique Polyurethane Elastomer)ni ubwoko bugaragara bwa plastike. Bitewe no gutunganya neza, kurwanya ikirere, n'ibidukikije bikoreshwa cyane mu nganda zijyanye nk'ibikoresho by'inkweto, imiyoboro, film, film, imizingo, insinga.

Polhonethane Thermospemer Thermostlestique, izwi kandi nka thermourethane ya polyurethane ya reberi, amagambo ahinnye nka TPU, ni ubwoko bwa (ab) n-guhagarika liner polymer. A ni uburemere bukomeye bwa molecular (1000-6000) polyester cyangwa polyether, na b ni diorl irimo urunigi rugororotse rwa karubone ya karubone. Imiterere yimiti hagati ya AB ibice ni diisocyanate, mubisanzwe bihujwe na MDI.

Ibicuruzwa bya polmorethane reberi yishingikiriza ku mazi y'amazi cyangwa yoroheje yo guhuza iminyururu ya macromcolular, kandi izi nyubako zombi zo guhuza zirahinduka hamwe no kongera cyangwa kugabanuka ubushyuhe. Muburyo bwo gushonga cyangwa igisubizo, Ingabo ziterane ziracogora, kandi nyuma yo gukonja cyangwa gukemuka, imbaraga ziterabwoba rikomeye ihuza hamwe, subiza imitungo ikomeye.

Polyurethane thermoplamest the elastorsIrashobora gushyirwa mubwoko bubiri: polyester na polyether, hamwe nigice cyera kidasanzwe cyangwa inkingi hamwe nubucucike ugereranije na 1.10-125. Ubwoko bwa polyether bufite ubucucike bwo hasi kuruta ubwoko bwa polyester. Ubushyuhe bwinzibacyuho yikirahure bwubwoko bwa polyether ni 100.6-106.1 ℃, hamwe nubwoko bwa polyester ni 108.9-122.8 ℃. Ubushyuhe bworoshye bwubwoko bwa PolyEther na Polyester biri munsi ya -62 ℃, mugihe ubushyuhe buke bwubwoko bwa ether bukomeye kuruta ubwo bwoko bwa polyester.

Ibiranga indabyongero bya Eluvesicthasthasthast The Bormaplamestic Numurwango Witabiwe, Gukomera Byiza, imbaraga nyinshi, kurwanya ubushyuhe, kurwanya amavuta, no kurwanya ibidukikije, nibirwanya imiti, no kurwanya ibidukikije. Mu bihe bitoroshye, Hydrolysis ituje rya PolyEther esters irenga kure iy'igitabo cya poyiri.

Polourethane thermoplastique thermoplastique ntabwo ari uburozi kandi ifite impumuro, gukemurwa muri methyl ether, na dioxylfofuran, na Dimetilthide, Butarene, na acetone muburyo bukwiye. Bagaragaza leta itagira ibara kandi iboneye kandi bafite ububiko bwiza bwo kubika.
