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

1,2,4-Benzenetricarboxylic anhydride (BTCA) e sebeletsa mesebetsi e mengata liindastering tse fapaneng ka lebaka la thepa ea eona e feto-fetohang. Lefapheng la k'hemistri ea polymer, e sebetsa e le moemeli oa ho hokahanya le monomer ea arabelang tlhahisong ea li-resin tsa thermoset, joalo ka li-resin tsa polyester le epoxy. Li-resin tsena li fumana ts'ebeliso ho li-coatings, li-glues, li-composites le metsoako ea ho bopa, e tlatsetsang ho ntlafatseng matla a thepa, ho hanyetsa mocheso le ho tšoarella ha lik'hemik'hale. Ho feta moo, BTCA e sebelisoa tlhahisong ea li-polymer tse sebetsang hantle joalo ka li-polyimides, moo e sebetsang e le motheo oa bohlokoa. Ho kenyelletsoa ha eona liketane tsa polymer ho ntlafatsa botsitso ba tsona ba mocheso, matla a mechini le thepa ea dielectric, ho etsa hore e lokele lits'ebetso tsa elektroniki, lifofane le lifilimi tse ikhethang. Ha ho etsoa li-coatings le li-linings tse sa senyeheng ke mafome, BTCA e bapala karolo ea bohlokoa joalo ka moemeli oa ho folisa le crosslinker. Ha e kopantsoe le litsamaiso tsa epoxy kapa polyurethane, e eketsa khanyetso ea lik'hemik'hale le ho khomarela ha li-coat tse sebelisoang ho sireletsa libaka tsa tšepe lits'ebetsong tsa leoatle, tsa indasteri le tsa meralo ea motheo. Ho feta moo, e sebelisoa e le moemeli oa chelating lits'ebetsong tsa kalafo ea metsi. Bokhoni ba eona ba ho phunya li-ion tsa tšepe bo thusa ho thibela ho thehoa ha sekala le ho bola lits'ebetsong tsa kabo ea metsi, bo tlatsetsa ntlafatsong ea boleng ba metsi le nako e telele ea meralo ea motheo. Ho feta moo, BTCA e sebetsa e le selelekela ho qaptjoeng ha metsoako ea meriana le lik'hemik'hale tse ikhethang. Ho arabela ha eona le lihlopha tsa eona tse sebetsang li e etsa ea bohlokoa bakeng sa nts'etsopele ea metsoako ea lik'hemik'hale e ikhethileng e etselitsoeng litlhoko tse ikhethileng tsa indasteri le meriana. Ho feta moo, e sebelisoa tlhahisong ea lintho tse thibelang malakabe le lintho tse ling tse hanelang mocheso bakeng sa polasetiki le masela, e tlatsetsang ntlafatsong ea polokeho ea mollo le botsitso ba mocheso lits'ebetsong tse fapaneng tsa bareki le tsa indasteri. Ka kakaretso, lits'ebetso tse fapaneng tsa 1,2,4-benzenetricarboxylic anhydride li kenyelletsa k'hemistri ea polymer, li-polymer tse sebetsang hantle, liphahlo tse hanelang malakabe, kalafo ea metsi, meriana, lintho tse thibelang malakabe le lik'hemik'hale tse ikhethang. Thepa ea eona e feto-fetohang e thusa ho ntlafatsa ts'ebetso ea thepa, ho sireletsa khahlanong le ho senyeha, le ho nolofalletsa tlhahiso ea lisebelisoa tse tsoetseng pele liindastering tse ngata.
