Hāʻawi kā mākou BPDA dianhydride i nā ʻano waiwai kūʻokoʻa e hoʻokō i nā pono like ʻole o nā ʻoihana like ʻole.ʻO kona kūpaʻa wela kūikawā, me kahi helu heheʻe ma luna o 300°C, hōʻoia i kona hilinaʻi i nā noi wela kiʻekiʻe.Eia kekahi, hōʻike ia i nā waiwai insulation uila maikaʻi loa, e hana ana i kahi koho kūpono no ka hoʻohana ʻana i nā mea uila a me nā mea insulation.
Hāʻawi kēia pūhui versatile i ka solubility kupaianaha i nā mea hoʻoheheʻe organik like ʻole, e ʻae ana i nā kaʻina hana maʻalahi a me ka hoʻohui maʻalahi i nā ʻano hana like ʻole.Inā i loko o ka hana ʻana i nā polymers kiʻekiʻe, nā mea hoʻohui kiʻekiʻe, a i ʻole nā palapala kūikawā, ʻo kā mākou BPDA dianhydride e lawelawe ma ke ʻano he catalyst no ka hana hou.
Eia kekahi, ʻo kona kūpaʻa kemika kūʻokoʻa e hiki ai iā ia ke kū i nā kaiapuni kūwaho, e lilo ia i mea koho maikaʻi loa no nā noi i ka hana kemika, ka hoʻokaʻawale ʻana i ke kinoea, a me nā uhi pale-corrosion.ʻO kona ikaika a me ka paʻakiki ʻokoʻa e kōkua pū i kona kūleʻa i nā mea ʻenekinia, kahi o ka lōʻihi a me ka hilinaʻi nā kumu nui.
At Wenzhou Blue Dolphin Mea Hou Co.ltdʻO ka maikaʻi a me ka maʻemaʻe ka mea nui.Loaʻa kā mākou BPDA dianhydride i ka hoʻāʻo a me ka nānā ʻana e hōʻoia i ka hoʻokō ʻana i nā kūlana ʻoihana kiʻekiʻe.Ke hana luhi nei kā mākou hui o nā ʻoihana loea e hōʻoia i ka paʻa a me ka hilinaʻi o kēia pūhui koʻikoʻi, e ʻae ana i kā mākou mea kūʻai aku e hoʻomaka i kā lākou mau papahana me ka hilinaʻi loa.
