Pyromellitic dianhydride (PMDA)
Pyromellitic Anhydride (PMDA) chinhu chakabikwa chekupisa chinodzivirira polyimide resins, mafirimu uye machira.
PMDA inonyanya kushandiswa senge yepakati yemafirimu epolyimide pamwe ne polyimide yakavakirwa composite zvinhu mune anochinjika akadhindwa edunhu mabhodhi, tepi otomatiki bonding, magineti waya insulation, uye zvimwe.
kushandiswa kwepamusoro kwekushanda.
Inoshandiswawo semushonga wekurapa epoxy resins anoshandiswa mukuumba hupfu (kugadzira zvikamu zvemhete dzechisimbiso, thrust washers, yakakosha gaskets kana thermal nemagetsi insulators), zvinonamira uye machira.
Shanghai Runwu Chemical Technology Co. Ltd ikemikari bhizinesi chigadzirwa R & D, kugadzira, kutengesa, seimwe yekuona.Isu tinovimba nekugona kutsvagisa kwakasimba uye tekinoroji yakakura, kukurumidza kusimuka muindasitiri yemakemikari, tichivimba nesainzi nekuvandudza tekinoroji, kupa vatengi zvigadzirwa zvemhando yepamusoro ndizvo zvatinogara tichitsvaga.
Isu tinonyanya kubata ne organic intermediates, noble metal catalyst, nano zvinhu, isingawanzo pasi.Zvinhu izvi zvinoshandiswa zvakanyanya mumakemikari, mushonga, biology, kuchengetedza kwezvakatipoteredza, simba idzva, nezvimwe.
Nekutanga-kirasi chigadzirwa mhando uye akanakisa tekinoroji masevhisi, Isu takakunda kurumbidzwa kwetsika.Panguva imwe chete, mukusimudzira, kambani yedu inonamatira kubatirana pamwe nemakambani epamba uye ekunze, masangano ekutsvagisa kwesainzi, mayunivhesiti exchange, kuitira kuvandudza R & D uye kugona kwekugadzira, akazvipira kupa vatengi zvimwe zvigadzirwa zvemhando yepamusoro uye masevhisi.
