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

He maha ngā mahi a te 1,2,4-Benzenetricarboxylic anhydride (BTCA) puta noa i ngā ahumahi rerekē nā ōna āhuatanga maha. I roto i te mara o te matū polymer, ka mahi hei kaihoko hononga whakawhiti me te monomer tauhohe i roto i te hanga o ngā kapia thermoset, pērā i te polyester me te epoxy resins. Ka kitea ngā tono o ēnei kapia i roto i ngā paninga, ngā piripiri, ngā hiato, me ngā matū hanga, e whai wāhi ana ki te whakapai ake i te kaha o te rauemi, te ātete wera, me te roa o te matū. I tua atu, ka whakamahia te BTCA i roto i te hanga o ngā polymer mahi-teitei pērā i te polyimides, hei poraka hanga matua. Ko tōna whakaurunga ki roto i ngā mekameka polymer ka whakarei ake i tō rātou pumau wera, kaha miihini, me ngā āhuatanga dielectric, ka pai mō ngā tono i roto i ngā hikohiko, te rererangi, me ngā kiriata motuhake. I roto i te hanganga o ngā paninga me ngā arai ātete-waikura, ka whai wāhi nui te BTCA hei kaihoko whakaora me te hononga whakawhiti. Ina honoa ki ngā pūnaha epoxy, polyurethane rānei, ka whakarei ake i te ātete matū me te piri o ngā paninga e whakamahia ana hei tiaki i ngā mata whakarewa i roto i ngā tono moana, ahumahi, me ngā hanganga. I tua atu, ka kitea te tono hei kaihoko chelating i roto i ngā tukanga maimoatanga wai. Ko tōna kaha ki te pupuri i ngā katote whakarewa ka āwhina i te aukati i te hanganga unahi me te waikura i roto i ngā pūnaha tohatoha wai, ka whai wāhi ki te whakapai ake i te kounga o te wai me te roa o te hanganga. Hei tāpiri, ko te BTCA te matū matua i roto i te hanganga o ngā takawaenga rongoā me ngā matū motuhake. Nā tōna tauhohenga me ngā rōpū mahi ka whai hua mō te whakawhanake i ngā matū ritenga kua whakaritea mō ngā whakaritenga ahumahi me te rongoā. Hei tāpiri, ka whakamahia i roto i te hanga o ngā aukati mura me ngā tāpiringa ātete wera mō ngā kirihou me ngā kakahu, ka whai wāhi ki te whakarei ake i te haumaru ahi me te pumau wera i roto i ngā tono kaihoko me te ahumahi. I te nuinga, ko ngā tono kanorau o te 1,2,4-benzenetricarboxylic anhydride e kapi ana i te matū polymer, ngā polymer mahi-teitei, ngā paninga ātete-waikura, te maimoatanga wai, ngā rongoā, ngā aukati mura, me ngā matū motuhake. Ko ōna āhuatanga maha ka whai wāhi ki te whakarei ake i te mahi rauemi, te tiaki i te pirau, me te whakahohe i te hanga rauemi matatau puta noa i ngā ahumahi maha.
