Kupu Whakataki
Ko te 2,2′-Bis(trifluoromethyl) -4,4′-diaminobiphenyl, e mōhiotia ana ko BTFMB, he pūhui waro. E whai ake nei he kupu whakataki mo ona rawa, ona whakamahinga, tikanga hanga me nga korero haumaru:
Kounga:
- Te ahua: Te paura tioata ma
- Kare e rewa i roto i te wai, paku memeha ki te ether me te benzene, ka whakarewahia i roto i nga whakarewa waro penei i te waipiro.
Whakamahia:
- Ko te 2,2′-Bis(trifluoromethyl)-4,4′-diaminobiphenyl he takawaenga pararopi nui, e whakamahia ana i roto i te whakahiatotanga o nga pūhui polymer me nga polymers
- Ka taea te whakamahi ki te whakarite i nga polymers me te pumau o te pāmahana teitei, nga taonga hiko me te miihini pai, penei i te polyimide, polyetherketone, etc
- Ka taea hoki te whakamahi i te BTFMB hei rauemi mata mo nga whakakorikori, taapiri paninga, taonga hiko, aha atu.
Tikanga:
- Ko te whakahiatotanga o te 2,2′-bis(trifluoromethyl)-4,4′-diaminobiphenyl i te nuinga o te wā ka haere ma te tauhohenga maha-taahiraa
- Ko te tikanga motuhake ko te hydroxymethylation o te methacrylonitrile me te 4,4′-diaminobiphenyl ki te whiwhi i tetahi hua takawaenga, ka whai i te trifluoromethylation ki te whiwhi i te hua whaainga.
Mōhiohio Haumaru:
- Ko te 2,2′-Bis(trifluoromethyl)-4,4′-diaminobiphenyl he pūhui pararopi pea he paitini me te whakapataritari
- I te wa e whakamahia ana me te rokiroki, me karohia te whakapiri atu ki nga matū waiora kaha me nga waikawa kaha
- I te wa e whakahaere ana me te tuku para, me whai ki nga ture me nga ture o te rohe
