Njikọta Polyimide

• Ihe nkiri ndị nwere arụmọrụ dị elu: Ọ nwere ike ịnweta mmeghachi omume polycondensation site na ngwakọta diamine iji mepụta ihe nkiri polyimide. Ihe nkiri ndị a nwere ezigbo iguzogide okpomọkụ dị elu. Ọbụna n'ebe okpomọkụ dị elu karịa 200 °C, ha ka nwere ike ịnọgide na-enwe ezigbo ihe onwunwe igwe na mkpuchi eletriki. Ya mere, a na-ejikarị ha eme ihe n'ọhịa ụgbọelu maka nchekwa mkpuchi nke moto na ngwa eletriki ma ọ bụ dị ka ihe ndabere maka bọọdụ sekit ebipụtara na-agbanwe agbanwe.
• Plastik Injinia: Plastik injinia polyimide a na-emepụta nwere ike dị elu, ezigbo nkwụsi ike, ma na-eguzogide iyi. Enwere ike ịkpụ ha site na ntụtụ iji mepụta ụfọdụ akụkụ ziri ezi yana ihe achọrọ siri ike maka ihe eji arụ ọrụ, dị ka obere brackets gburugburu injin ụgbọelu na akụkụ nnyefe n'ime elekere igwe dị elu.
• Ebe mkpuchi: Mkpuchi Polyimide nke e ji BDDA mee nwere ezigbo iguzogide nchara kemịkalụ. Mgbe etinyere ya na mgbidi dị n'ime tankị nchekwa kemịkalụ na reactor, ha nwere ike iguzogide mbibi nke asịd dị iche iche, ntọala, na ihe mgbaze organic ruo ogologo oge, na-eme ka akụrụngwa ahụ dị ndụ. N'otu oge ahụ, ha nwekwara ezigbo iguzogide okpomọkụ. Mgbe a na-ekpuchi ya na paịpụ ikuku na ihe mkpuchi injin dị elu, ha agaghị agbaze ngwa ngwa n'ihi oke okpomọkụ.
• Ihe e ji eriri rụọ: A na-eji ya emepụta eriri ndị nwere arụmọrụ dị elu. Eriri polyimide ndị a na-emepụta nwere ike dị elu, modulus dị elu, na nkwụsi ike okpomọkụ dị mma. A na-ejikarị ha emepụta uwe ndị na-anaghị agba ọkụ, eriri pụrụ iche maka ụgbọelu, wdg, na-enye nchebe a pụrụ ịdabere na ya maka ndị ọrụ na akụrụngwa n'ọnọdụ okpomọkụ dị elu na nke dị oke egwu.
