3,3′,4,4′-Biphenyltetracarboxylic dianhydride/BPDA cas:2420-87-3
BPDA dianhydride yathu ili ndi zinthu zambiri zapadera zomwe zimakwaniritsa zosowa zosiyanasiyana zamafakitale osiyanasiyana.Kukhazikika kwake kwapadera kwamafuta, komwe kumasungunuka pamwamba pa 300°C, imatsimikizira kudalirika kwake pamagwiritsidwe ntchito otentha kwambiri.Kuphatikiza apo, imawonetsa zinthu zabwino kwambiri zotchinjiriza magetsi, zomwe zimapangitsa kuti ikhale chisankho chabwino kwambiri kuti chigwiritsidwe ntchito pamagetsi ndi zida zamagetsi.
Gulu losunthikali limapereka kusungunuka kodabwitsa mu zosungunulira zosiyanasiyana za organic, zomwe zimapangitsa kuti pakhale njira zosinthika zopangira komanso kuphatikiza kosavuta m'mapangidwe osiyanasiyana.Kaya ndi kupanga ma polima apamwamba kwambiri, zophatikizika zapamwamba, kapena zokutira zapadera, BPDA dianhydride yathu imagwira ntchito ngati chothandizira kukonzanso.
Kuphatikiza apo, kukana kwake kwapadera kwamankhwala kumatheketsa kupirira madera ankhanza, ndikupangitsa kuti ikhale chisankho chabwino kwambiri pakugwiritsa ntchito mankhwala, kupatukana kwa gasi, ndi zokutira zosagwira dzimbiri.Mphamvu zake zapadera zamakina komanso kusasunthika kumathandizanso kuti apambane muzopangapanga, pomwe kulimba ndi kudalirika ndizofunikira kwambiri.
At Malingaliro a kampani Wenzhou Blue Dolphin New Material Co.ltd, khalidwe ndi chiyero ndizofunika kwambiri.BPDA dianhydride yathu imayesedwa mozama ndikuwunika kuti iwonetsetse kuti ikukwaniritsa miyezo yapamwamba kwambiri yamakampani.Gulu lathu la akatswiri odziwa zambiri limagwira ntchito molimbika kutsimikizira kusinthasintha ndi kudalirika kwa gulu lofunikirali, kulola makasitomala athu kuti ayambe ntchito zawo molimba mtima.
