3,3′,4,4′-Biphenyltetracarboxylic dianhydride/BPDA cas:2420-87-3

Inkcazelo emfutshane:

I-3,3′,4,4′-biphenyltetracarboxylic dianhydride, ekwabizwa ngokuba yi-BPDA dianhydride, ngumgubo omhlophe wekristale ophuma kwintsapho ye-dianhydride enevumba elimnandi.Ifomula yayo yeekhemikhali, i-C20H8O6, ibonisa ukucwangciswa okuntsonkothileyo kwee-athomu ezinoxanduva lweempawu zayo ezikhethekileyo.I-BPDA dianhydride ibonisa uzinzo oluphezulu lwe-thermal kunye neekhemikhali, iyenza ibe yinto efunwa kakhulu kwihlabathi lezinto zesayensi kunye nobuchwepheshe.


Iinkcukacha zeMveliso

Iithegi zeMveliso

I-BPDA yethu dianhydride iqhayisa ngoluhlu lweepropathi ezizodwa ezibonelela ngeemfuno ezahlukeneyo zamashishini ahlukeneyo.Uzinzo olukhethekileyo lwe-thermal, kunye nendawo yokunyibilika ngaphezulu kwe-300°C, iqinisekisa ukuthembeka kwayo kwizicelo zobushushu obuphezulu.Ngaphaya koko, ibonisa iipropathi ezigqwesileyo zokugquma umbane, iyenza ibe lolona khetho lufanelekileyo lokusetyenziswa kwizinto zombane kunye nemathiriyeli yokugquma.

Le khompawundi eguquguqukayo ibonelela nge-solubility ephawulekayo kwiintlobo ezahlukeneyo ze-solvents eziphilayo, ezivumela iinkqubo zokuvelisa eziguquguqukayo kunye nokudibanisa lula kwiindlela ezahlukeneyo.Nokuba ikwimveliso yeepolymers ezisebenza ngokuphezulu, imidibaniso ephucukileyo, okanye ityatyekwe ezikhethekileyo, i-BPDA dianhydride yethu isebenza njengesixhobo sokwenza izinto ezintsha.

Ngaphaya koko, ukuxhathisa kwayo okukhethekileyo kweekhemikhali kuyenza ikwazi ukumelana nemekobume endlongondlongo, iyenze ibe lolona khetho lubalaseleyo losetyenziso lwemichiza, ulwahlulo lwegesi, kunye neengubo ezinganyangekiyo kukutya.Amandla ayo akhethekileyo omatshini kunye nokuqina kwakhona kunegalelo kwimpumelelo yayo kwizinto zobunjineli, apho ukuqina kunye nokuthembeka zizinto eziphambili.

At I-Wenzhou Blue Dolphin New Material Co.ltd, umgangatho kunye nokucoceka kubaluleke kakhulu.I-BPDA dianhydride yethu ivavanywa ngokungqongqo kwaye ihlalutywe ukuqinisekisa ukuba ihlangabezana neyona migangatho iphezulu yoshishino.Iqela lethu leengcali ezinamava lisebenza ngokungadinwayo ukuqinisekisa ukungaguquguquki kunye nokuthembeka kwale khompani ibalulekileyo, ivumela abathengi bethu ukuba baqalise iiprojekthi zabo ngokuzithemba ngokupheleleyo.
