Ithimba lethu lobunjiniyela elikhethekile livame ukulungela ukukunikeza ukubonisana kanye nempendulo. Singakwazi futhi ukukulethela amasampula amahhala ukuze kuhlangatshezwane nemininingwane yakho. Imizamo emihle cishe izokhiqizwa ukukunikeza insizakalo nezixazululo ezizuzisa kakhulu. Uma ufuna ukuba nesithakazelo enkampanini yethu kanye nezixazululo, kufanele uxhumane nathi ngokusithumelela ama-imeyili noma usishayele ucingo ngokushesha. Ukuze wazi izixazululo zethu kanye nebhizinisi. Uma ufuna okwengeziwe, uzokwazi ukuza efektri yethu ukuzoyibona. Sizohlala samukela izivakashi ezivela kuwo wonke umhlaba enkampanini yethu. o ukwakha ibhizinisi. izingxoxo nathi. Khumbula ukuzizwa ukhululekile ukukhuluma nathi ngenhlangano. futhi sikholelwa ukuthi sizokwabelana ngolwazi oluhle kakhulu lokuhweba nabo bonke abathengisi bethu.
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.
| Into | Okujwayelekile |
| Ukubukeka | Amakristalu amhlophe |
| Miphuzu lokunciphisa | 286℃ -288℃ |
| Ukuncintisana kwe-asidi yamahhala | ≤0.5wt% |

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%.
