3,3′,4,4′-Biphenyltetracarboxylic dianhydride/BPDA cas:2420-87-3
O la matou BPDA dianhydride o loʻo faʻaalia le tele o mea faʻapitoa e fetaui ma manaʻoga eseese o pisinisi eseese.O lona tulaga mautu fa'avela, fa'atasi ai ma se mea fa'afefete i luga a'e o le 300°C, faʻamautinoa lona faʻatuatuaina i talosaga maualuga-vevela.E le gata i lea, o loʻo faʻaalia ai mea e sili ona lelei le faʻaogaina o le eletise, ma avea ai ma filifiliga lelei mo le faʻaogaina i mea faʻaeletoroni ma mea faʻapipiʻi.
O lenei mea fa'apipi'i fa'apitoa e ofoina atu le solubility mata'ina i solu fa'alela'au eseese, fa'ataga mo faiga fe'avea'i gaosiga ma faigofie tu'ufa'atasia i fa'asologa eseese.Pe o loʻo i totonu o le gaosiga o polymers maualuga, faʻapipiʻi maualuga, poʻo faʻapitoa faʻapitoa, o le matou BPDA dianhydride o loʻo avea ma faʻamalosi mo le faʻafouina.
E le gata i lea, o lona tetee atu i vailaau faʻapitoa e mafai ai ona tatalia siʻosiʻomaga faʻamalosi, ma avea ai ma filifiliga sili ona lelei mo faʻaoga i le gaosiga o vailaʻau, vavae ese o kesi, ma faʻamalo faʻafefe.O lona malosi fa'ainisinia fa'apitoa ma le ma'a'a'a e saofagā fo'i i lona manuia i mea fa'ainisinia, lea o le tumau ma le fa'amaoni o mea taua.
At Wenzhou Blue Dolphin New Material Co.ltd, o le lelei ma le mama e sili ona taua.O la matou BPDA dianhydride e faʻataʻitaʻiina ma suʻesuʻega malosi ina ia mautinoa e ausia tulaga maualuga o alamanuia.O la matou 'au o tagata tomai fa'apolofesa e galulue ma le le fiu e fa'amautinoa le tumau ma le fa'amaoni o lenei fa'alapotopotoga taua, fa'ataga a matou tagata fa'atau e amata a latou poloketi ma le mautinoa atoatoa.
