dziwitsani:
M'munda wa zida zapamwamba,pyromellitic dianhydride(PMDA) yakula ngati chinthu chofunikira kwambiri popanga utomoni wa polyimide wosamva kutentha, mafilimu ndi zokutira.Ndi kukhazikika kwake kwamafuta komanso kusinthasintha, PMDA yakhala chisankho choyamba pamapulogalamu ambiri ochita bwino kwambiri.Mu blog iyi, tikuwunika kuthekera kwakukulu kwa ma PMDA ndi gawo lawo pakusintha mafakitale osiyanasiyana.
Kukana Kutentha Kwambiri:
PMDA ili ndi kukana kutentha kwambiri ndipo ndi yabwino kwazinthu zopangira mafilimu a polyimide.Makanemawa amagwiritsidwa ntchito kwambiri m'ma board osinthika osindikizira, tepi yolumikizira yokha komanso kutsekereza waya wa maginito.Mwa kuphatikiza PMDA, zidazi zimatha kupirira kutentha kwambiri popanda kusiya kukhulupirika kwawo.M'mapulogalamu omwe kusungunula kwamafuta kumakhala kofunikira, mafilimu a PMDA-based polyimide amapereka magwiridwe antchito osagwirizana.
Powerpack Composites:
PMDA imagwiranso ntchito yofunika kwambiri popanga zinthu zopangidwa ndi polyimide.Zophatikizirazi zimaphatikiza kukana kwamphamvu kwa kutentha kwa polyimide ndi mphamvu ndi zopepuka zazinthu zina.Chotsatira chake, mafakitale monga ndege, magalimoto ndi zamagetsi amapindula ndi chitukuko cha zigawo zapamwamba zogwira ntchito.Kaya akupanga zida za ndege kapena kuwongolera kulimba kwa zida zamagetsi, zida za PMDA zimapereka yankho lopambana.
Hardener:
Kuphatikiza pa ntchito yake mu polyimide resins, PMDA ingagwiritsidwenso ntchito ngati mankhwala ochiritsira ma epoxy resins mu ufa woumba.Ntchitoyi imalola kuti pakhale zida zapadera monga mphete zosindikizira, ma thrust washers, spacers ndi insulators.Powonjezera PMDA ngati mankhwala ochiritsira, epoxy resin imatha kupititsa patsogolo kutentha ndi makina, potero kupititsa patsogolo ntchito yake yonse ndikukulitsa ntchito yake.
Innovation Roadmap:
Zinthu zabwino kwambiri za PMDA zimapangitsa kuti ikhale yofunikira kwambiri pakufunafuna zatsopano.Mafakitale amadalira mphamvu yake yapadera yopirira kutentha kwambiri kuti atsimikizire chitetezo ndi kudalirika kwa mankhwala awo.Pokankhira malire a kukana kwamafuta, ma PMDA amatsegula mwayi watsopano wopita patsogolo pazamagetsi, zakuthambo, ndi magawo ena omwe kulondola ndi kudalirika ndikofunikira.
Pomaliza:
Pyromellitic dianhydride (PMDA) ndiwosintha kwenikweni pamasewera apamwamba.Kukana kwambiri kutentha kwake komanso kusinthasintha kwake kumapangitsa kuti ikhale yofunika kwambiri popanga utomoni wa polyimide, mafilimu ndi ma composites.Pamene mafakitale akuyesetsa kuti apange zatsopano komanso kudalirika, PMDA imapereka maziko ofunikira kukankhira malire a kukana kutentha.Pokhala ndi PMDA pachitsogozo, titha kuyembekezera kuwona kupita patsogolo kwapang'onopang'ono pamapulogalamu apamwamba, kuwonetsetsa kuti zinthu zili bwino komanso chitetezo kwazaka zikubwerazi.
