1,2,4-Benzenetricarboxylicanhydride CAS:552-30-7

1,2,4-Benzenetricarboxylic anhydride (BTCA) imagwira ntchito zosiyanasiyana m'mafakitale osiyanasiyana chifukwa cha mphamvu zake zosiyanasiyana. Mu gawo la polymer chemistry, imagwira ntchito ngati cholumikizira cholumikizira ndi monomer yogwira ntchito popanga ma thermoset resins, monga ma polyester ndi ma epoxy resins. Ma resins awa amagwiritsidwa ntchito mu zokutira, zomatira, zophatikizika, ndi zinthu zopangira, zomwe zimathandiza kuti zinthu zikhale zolimba, kukana kutentha, komanso kulimba kwa mankhwala. Kuphatikiza apo, BTCA imagwiritsidwa ntchito popanga ma polima ogwira ntchito kwambiri monga ma polyimides, komwe imagwira ntchito ngati maziko ofunikira. Kuphatikizidwa kwake mu unyolo wa polima kumawonjezera kukhazikika kwawo kwa kutentha, mphamvu yamakina, ndi mphamvu za dielectric, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito mu zamagetsi, ndege, ndi mafilimu apadera. Pakupanga zokutira ndi zolumikizira zosagwirizana ndi dzimbiri, BTCA imagwira ntchito yofunika kwambiri ngati chothandizira kuchiritsa ndi cholumikizira cholumikizira. Ikaphatikizidwa ndi epoxy kapena polyurethane systems, imawonjezera kukana kwa mankhwala ndi kumamatira kwa zokutira zomwe zimagwiritsidwa ntchito poteteza pamwamba pa zitsulo m'mafakitale, mafakitale, ndi zomangamanga. Kuphatikiza apo, imagwiritsidwa ntchito ngati chothandizira chelating mu njira zochizira madzi. Kutha kwake kusunga ma ayoni achitsulo kumathandiza kupewa kupangika kwa ma scale ndi dzimbiri m'machitidwe ogawa madzi, zomwe zimathandiza kuti madzi azikhala bwino komanso kuti zinthu zikhale bwino. Kuphatikiza apo, BTCA imagwira ntchito ngati njira yoyambira kupanga mankhwala ndi mankhwala apadera. Kuchita kwake bwino komanso magulu ake ogwira ntchito kumapangitsa kuti ikhale yofunikira pakupanga mankhwala apadera omwe amapangidwa kuti agwirizane ndi zofunikira zamakampani ndi zamankhwala. Kuphatikiza apo, imagwiritsidwa ntchito popanga zinthu zoletsa moto ndi zowonjezera zosatentha za pulasitiki ndi nsalu, zomwe zimathandiza kuti chitetezo cha moto chikhale cholimba komanso kutentha m'magwiritsidwe osiyanasiyana a ogula ndi mafakitale. Ponseponse, ntchito zosiyanasiyana za 1,2,4-benzenetricarboxylic anhydride zimaphatikizapo mankhwala a polymer, ma polima ogwira ntchito kwambiri, zokutira zoletsa dzimbiri, mankhwala amadzi, mankhwala, zoletsa moto, ndi mankhwala apadera. Kapangidwe kake kosiyanasiyana kamathandizira kukulitsa magwiridwe antchito azinthu, kuteteza kuwonongeka, komanso kulola kupanga zinthu zapamwamba m'mafakitale osiyanasiyana.
