Mirathane® Polycarbonate-based TPU

Ma diols a polycarbonate ndi mtundu wa ma polyol omwe ali ndi mawonekedwe abwino kwambiri, ndipo maunyolo awo a molekyulu amakhala ndi magawo obwereza opangidwa ndi carbonate. M'zaka zaposachedwa, amawonedwa ngati zida zopangira m'badwo watsopano wa thermoplastic polyurethane elastomers. Chifukwa chake, ngati gawo lofewa, limagwira ntchito bwino pamagawo onse a TPU ya polycarbonized TPU yopangidwa ndi isocyanate ndi chain extender.

Poyerekeza ndi poliyesitala TPU, si ali ndi mphamvu mkulu, mkulu kutentha kukana ndi makhalidwe ena, komanso ali kwambiri kukana hydrolysis. Poyerekeza ndi polyether TPU, sikuti imakhala ndi kukana kwa hydrolysis, komanso imakhala ndi mphamvu zambiri, kukana kutentha kwabwino komanso kukhazikika kwa okosijeni.

Chifukwa chakuchita bwino kwambiri, m'zaka zaposachedwa, TPU ya polycarbonized yakhala ikugwiritsidwa ntchito kwambiri popanga mafakitale, zida zamankhwala ndi magawo ena. Pogwiritsa ntchito kukana kwake, mphamvu yayikulu, kukana kutentha kwabwino, kukana kwa hydrolysis, imatha kugwiritsidwa ntchito ngati matayala apansi pamadzi ndi zida zina zapadera. Pogwiritsa ntchito kukana kwake kwa hydrolysis, mphamvu yayikulu, kukana kwa okosijeni, etc., imatha kupanga mipope yapadera yolimbana ndi chlorine ndi zinthu zina zamakampani. Ndi kukana kwake kwa okosijeni kwabwino komanso kukhazikika m'thupi la munthu, chitha kugwiritsidwa ntchito ngati mtundu watsopano wazinthu zopangira mankhwala.

Ndi zaka zambiri zachitukuko cha kafukufuku ndi zochitika zopanga, Miracll imatha kutulutsa 80A-95A kuuma kwa Polycarbonate TPU monga C80, C85, C90, C95.

M'tsogolomu, tidzapanga zida zatsopano zabwino kwambiri malinga ndi zolinga ndi malo osiyanasiyana.
