Pyromellitic dianhydride (PMDA)
Pyromellitic Anhydride (PMDA) waa walxo ceeriin ah oo loogu talagalay kuleyl u adkeysiga resins polyimide, filimada iyo dahaarka.
PMDA waxaa inta badan loo codsadaa sidii dhex dhexaad u ah filimada polyimide iyo sidoo kale polyimide oo ku salaysan walxo isku dhafan oo ku jira looxyada wareegyada daabacan ee dabacsan, cajalado iswada duuban, dahaarka fiilada magnetic, iyo kuwa kale
codsiyada waxqabadka sare.
Waxa kale oo loo istcimaalaa sidii daawaynta resins epoxy ee loo isticmaalo samaynta budada (si loo soo saaro qaybo loogu talagalay giraangiraha shaabadda, mashiinnada riixa, gaasaska gaarka ah ama dahaadhka kulaylka iyo korantada), koollada iyo dahaarka.
Shanghai Runwu Chemical Technology Co. Ltd waa wax soo saarka kiimikada R & D, wax soo saarka, iibinta, sida mid ka mid ah ogaanshaha.Waxaan ku tiirsannahay awoodda cilmi-baarista xooggan iyo tignoolajiyada qaan-gaarka ah, waxay leeyihiin koror degdeg ah warshadaha kiimikada, ku tiirsanaanta horumarinta sayniska iyo tignoolajiyada, si aan u siino macaamiisha alaab tayo sare leh waa dabagalkeena joogtada ah.
Waxaan inta badan la macaamilnaa dhexdhexaadiyeyaasha organic, kicinta birta sharafta leh, alaabta nano, dhul naadir ah.Qalabkan waxaa si weyn loogu isticmaalaa kimistariga, daawada, bayoolajiga, ilaalinta deegaanka, tamarta cusub, iwm.
Iyada oo leh tayada badeecada heerka koowaad iyo adeegyo farsamo oo heer sare ah, Waxaan ku guuleysanay ammaanta kastamka.Isla mar ahaantaana, horumarinta, shirkadeena waxay u hoggaansamaan iskaashiga shirkadaha gudaha iyo kuwa ajnabiga ah, hay'adaha cilmi-baarista sayniska, jaamacadaha sarrifka, si loo hagaajiyo R & D iyo awoodda wax soo saarka, oo ay ka go'an tahay in ay macaamiisha siiso alaab tayo leh iyo adeegyo.
