BPTA CAS:89604-92-2

He whānuitia te whakamahinga o te BPTA (Benzophenone-tetracarboxylic dianhydride) hei poraka hanga nui i roto i te hanganga o ngā polymer me ngā polyimides mahi-teitei, e whakanuia ana mō tō rātou pumau wera, kaha miihini, me te ātete matū. Ka kitea e ēnei rauemi ngā tono rerekē i roto i ngā ahumahi pēnei i te rererangi, te hikohiko, te motuka, me te whakawhitiwhiti kōrero, he mea nui ngā whakaritenga mahi uaua. Ka whakamahia ngā polymer me ngā polyimides i ahu mai i te BPTA ki te hanga rauemi hiato matatau, kiriata, paninga, piripiri, me ngā wāhanga hiko, e whai wāhi ana ki te whanaketanga o ngā hua mama, pakari, me te ātete pāmahana teitei. Hei tāpiri, ka mahi ēnei rauemi hei paninga ārai me te tiaki mō ngā taputapu hiko me te hikohiko, e whakarei ake ana i tō rātou pono me te roa o te ora i roto i ngā taiao mahi uaua. Ka horapa te hiranga o te BPTA ki te mara o te microelectronics, e āwhina ana i te hanga rauemi motuhake mō te takai semiconductor, ngā papa porowhita, me ngā pūnaha microelectromechanical (MEMS), e āhei ai te whanaketanga i roto i te whakaitiiti me te mahi taputapu. Ko tana mahi i roto i te matū polymer ahumahi e whakaatu ana i tōna pānga ki te auahatanga hangarau me te pūtaiao rauemi, e akiaki ana i te ahunga whakamua i roto i te miihini, te hanga, me ngā momo rāngai e hiahia ana ki ngā rauemi matatau me ngā āhuatanga kua whakaritea. Mā te whakamahinga rautaki o te BPTA ka whai wāhi ki te whanaketanga tonu o ngā polymer me ngā polyimide mahi-teitei, e aro ana ki ngā hiahia hurihuri o ngā ahumahi hou, ā, ka taea ai te waihanga i ngā otinga auaha mō ngā wero hangarau uaua.
