I-Pyromellitic Dianhydride (PMDA) eyenziwe ngokwezifiso efektri 1,2,4,5-Benzenetetracarboxylic Dianhydride Benzene-1,2:4,5-Tetracar CAS 89-32-7 Isetshenziselwa i-Synthetic Resin Crosslinking Agent
Thatha umthwalo wemfanelo ogcwele wokuhlangabezana nazo zonke izidingo zamakhasimende ethu; ukufeza intuthuko eqhubekayo ngokukhuthaza ukukhula kwamakhasimende ethu; ube ngumlingani wokugcina ohlala njalo wokubambisana wamakhasimende futhi wandise izintshisekelo zamakhasimende ze-Factory Customized Pyromellitic Dianhydride (PMDA) 1,2,4,5-BenzenetetracarboxylicI-Dianhydride Benzene-1,2:4,5-Tetracar I-CAS 89-32-7Isetshenziselwa i-Synthetic Resin Crosslinking Agent, Sihlonipha isisekelo sethu esiyinhloko sokwethembeka enkampanini, ukubaluleka kwenkonzo futhi sizokwenza konke okusemandleni ethu ukunikeza abathengi bethu imikhiqizo nezixazululo ezisezingeni eliphezulu kanye nokusekelwa okukhulu.
Thatha umthwalo wemfanelo ogcwele wokuhlangabezana nazo zonke izidingo zamakhasimende ethu; ukufeza intuthuko eqhubekayo ngokukhuthaza ukukhula kwamakhasimende ethu; ube ngumlingani wokugcina ohlala njalo wokubambisana wamakhasimende futhi wandise izintshisekelo zamakhasimendeI-China Pmda kanye ne-CAS No. 89-32-7, Sakhe ubudlelwano obuqinile nobuhlala isikhathi eside nezinkampani eziningi kuleli bhizinisi phesheya kwezilwandle. Insizakalo esheshayo neyochwepheshe ngemuva kokuthengisa enikezwa yiqembu lethu labacebisi ijabulise abathengi bethu. Ulwazi olujulile kanye nemingcele evela emikhiqizweni kuzothunyelwa kuwe ukuze uthole noma yikuphi ukwaziswa okuphelele. Amasampula wamahhala angalethwa futhi inkampani ivakashele inkampani yethu. ePortugal ukuze kuxoxiswane yamukelekile njalo. Ngiyethemba ukuthi imibuzo izothunyelwa kuwe futhi yakhe ubudlelwano besikhathi eside.
I-pyromellitic dianhydride (efushaniswe ngokuthi i-PMDA), esetshenziswa kakhulu ekuhlanganiseni i-polyimide, ngoba i-polyimide inokumelana okuhle kakhulu nokushisa okuphezulu, ukumelana ne-asidi kanye ne-alkali, okuhle kakhulu Ngenxa yezakhiwo zayo zemishini, izakhiwo zikagesi kanye nokuqina kobukhulu, isetshenziswa kabanzi emikhakheni yobuchwepheshe obuphezulu njengezindiza, izindiza, ama-microelectronics kanye namandla e-athomu, anezidingo eziqinile ezakhiweni zezinto ezibonakalayo.

I-Pyromellitic dianhydride (PMDA) iyinto ebalulekile embonini yokwenziwa kwezinto eziphilayo, kanye nezinto eziyisisekelo zokusetshenziswa zokuthuthukiswa kwezinto ezintsha zamakhemikhali kanye nemikhiqizo yamakhemikhali amahle anenani eliphezulu. Isetshenziswa kakhulu ekukhiqizweni kwama-monomers e-polyimide, futhi ingasetshenziswa njenge-ejenti yokwelapha ye-epoxy resin kanye ne-ejenti yokuxhumanisa i-polyester resin, esetshenziswa ekwenziweni kwedayi eluhlaza okwesibhakabhaka ye-phthalocyanine kanye nezinye izinto ezibalulekile, njll., futhi inokusetshenziswa okubanzi. I-Pyromellitic dianhydride, eyaziwa nangokuthi i-homoanhydride, inesakhiwo esikhethekile sama-molecule futhi ingasetshenziswa ukukhiqiza izinto ezinokumelana nokushisa, ukufudumala kukagesi kanye nokumelana namakhemikhali, phakathi kwazo ukusetshenziswa okubaluleke kakhulu njenge-monolayer ye-polyimide. Yenziwe nge-aromatic diamine ukuthola ipulasitiki ye-polyimide, kodwa ubumsulwa be-pyromellitic dianhydride buphezulu kakhulu, okudingeka bube ngaphezu kwama-99%.
