3,3′,4,4′-Biphenyltetracarboxylic dianhydride/BPDA cas:2420-87-3
I-BPDA dianhydride yethu inoxhaxha lwezakhiwo ezihlukile ezihlangabezana nezidingo ezahlukahlukene zezimboni ezahlukahlukene.Ukuzinza kwayo okushisayo okukhethekile, ngephoyinti lokuncibilika ngaphezu kwama-300°C, iqinisekisa ukuthembeka kwayo ezinhlelweni zokushisa eziphezulu.Ngaphezu kwalokho, ikhombisa izakhiwo ezinhle kakhulu zokufakwa kukagesi, okuyenza ibe yinketho efanelekile ukuthi isetshenziswe ezingxenyeni ze-elekthronikhi nezinto zokufakelwa.
Le nhlanganisela ehlukahlukene inikezela ngokuncibilika okumangalisayo kuzincibilikisi ezihlukahlukene zezinto eziphilayo, okuvumela izinqubo zokukhiqiza eziguquguqukayo kanye nokuhlanganiswa okulula ekuhlanganiseni okuhlukahlukene.Kungakhathaliseki ukuthi kusekukhiqizweni kwama-polymers asebenza kahle kakhulu, izinhlanganisela ezithuthukisiwe, noma okokuhlanganisa okukhethekile, i-BPDA dianhydride yethu isebenza njenge-catalyst yokuqamba izinto ezintsha.
Ngaphezu kwalokho, ukumelana kwayo namakhemikhali okukhethekile kuyenza ikwazi ukumelana nezindawo ezinolaka, okuyenza ibe ukukhetha okuhle kakhulu ekusetshenzisweni kwamakhemikhali, ukuhlukaniswa kwegesi, kanye nezingubo ezimelana nokugqwala.Amandla ayo emishini akhethekile kanye nokuqina nakho kunomthelela empumelelweni yayo ezintweni zobunjiniyela, lapho ukuqina nokuthembeka kuyizici ezibalulekile.
At I-Wenzhou Blue Dolphin New Material Co.ltd, izinga nobumsulwa kubaluleke kakhulu.I-BPDA dianhydride yethu ihlolwa kanzima futhi ihlaziywe ukuze kuqinisekiswe ukuthi ihlangabezana namazinga aphezulu embonini.Ithimba lethu lochwepheshe abanolwazi lisebenza ngokuzikhandla ukuze liqinisekise ukungaguquguquki nokuthembeka kwale nhlanganisela ebalulekile, okuvumela amakhasimende ethu ukuthi aqale amaphrojekthi abo ngokuzethemba okuphelele.
