9,9-Bis(3,4-dicarboxyphenyl)fluorene Dianhydride/BPAF cas:135876-30-1
Hoʻohana nui ʻia ka BDFA ma ke ʻano he mea koʻikoʻi i ka synthesis o nā polymers a me nā mea hana kiʻekiʻe.ʻO kona ʻano molekole kūʻokoʻa, ʻo ia hoʻi ʻelua apo benzene i hoʻopili ʻia i ka iwi kuamoʻo fluorene, hāʻawi i nā waiwai wela a me nā mīkini i nā polymers hopena.
ʻO ke kūpaʻa wela ʻokoʻa o nā polymers-based BDFA e hiki ai iā lākou ke kū i nā wela kiʻekiʻe, e kūpono iā lākou no nā noi ma ka ʻoihana aerospace, automotive, a me nā ʻoihana uila.Hōʻike kēia mau polymers i ke kūpaʻa kūʻokoʻa i ka wela, UV radiation, a me ka corrosion kemika, e hōʻoiaʻiʻo ana i ko lākou lōʻihi a me ka lōʻihi i nā wahi koi.
Eia kekahi, loaʻa nā polymers i hoʻokumu ʻia BDFA i nā waiwai insulation uila maikaʻi loa, e hoʻolilo iā lākou i koho kūpono no nā noi uila a me ka uila.Hiki ke hoʻohana ʻia kēia mau polymers i ka hana ʻana i nā insulators, nā ʻāpana uila, a me nā papa kaapuni paʻi, kahi e pono ai ke hoʻemi ʻia ka conductivity uila.
Kaulana ʻia ʻo BDFA no kona hiki ke hoʻonui i ka ikaika mechanical a me ka rigidity o nā polymers.Ma ka hoʻokomo ʻana i ka BDFA i loko o nā matrices polymer, hōʻike nā mea i loaʻa i ka ikaika o ka tensile, ka pale ʻana i ka hopena, a me ke kūpaʻa ʻana.ʻO kēia ka mea kūpono iā lākou no nā noi i ke kūkulu ʻana, automotive, a me nā ʻoihana mea kūʻai aku.
Ma waho aʻe o kāna mau noi i nā polymers kiʻekiʻe, ʻike ʻo BDFA i ka pono i ka hana ʻana i nā kemika kūikawā, nā mea hoʻonaninani, a me nā puaʻa.Hāʻawi kona ʻano molekala kūʻokoʻa i nā manawa kūpono no ka hana maʻamau, e ʻae ana i nā mea noiʻi a me nā mea hana hana e hoʻomohala i nā mea hou me nā waiwai kūpono.
