Otu esi emeziwanye arụmọrụ nrapado elu nke ihe nkiri polyimide

Ihe nkiri Polyimide bụ ngwaahịa ihe nkiri na-ewu ewu ugbu a, yana ngwa dị iche iche na arụmọrụ dị mma. Agbanyeghị, n’oge eji, ụfọdụ ndị ahịa na ndị enyi ga-ezute nsogbu na arụmọrụ adhesion elu ya. Yabụ, otu esi emeziwanye arụmọrụ nrapado elu nke ihe nkiri polyimide? Ndị nrụpụta ọkachamara ga-enye azịza n’okpuru, bịa hụ.

Ihe nkiri Polyimide (PI) bụ ihe pụrụ iche nke sịntetik nke nwere ezigbo anụ ahụ na akụrụngwa yana nkwụsi ike eletriki na kemịkalụ dị mma. A na-eji ya eme ihe na mbara igwe, mkpuchi ọkụ eletrik, microelectronics na ụlọ ọrụ ndị ọzọ (dị ka oghere dielectric, oyi akwa mkpuchi, na akwa oyi akwa nke foil metal). N’ihi na ihe nkiri PI nwere ebe dị mma, ọrụ kemịkalụ dị ala, na nkwụsi ike na-adịghị mma na foil metal (aluminom foil, foil ọla kọpa, wdg). ), elu nke ihe nkiri PI kwesịrị ka a gwọọ ya ma ọ bụ gbanwee iji meziwanye nrapado nke elu PI.

Ka ọ dị ugbu a, na usoro ọgwụgwọ niile na usoro mgbanwe nke ihe nkiri polyimide, n’ihi usoro na ihe ndị na-eri ego, a na-amụba ọgwụgwọ acid-base. Ụfọdụ akwụkwọ akọpụtala na ụdị nkwalite a nke wettability na usoro nke adhesion, ma isi ọrụ nke ngwaahịa mmepụta ihe mgbe ọgwụgwọ enweghị akụkọ kwesịrị ekwesị na nlebara anya.

Site n’ịgwọ elu nke ihe nkiri polyimide na ngwọta oxalic acid, sodium hydroxide na mmiri desalted, na-enweghị emetụta àgwà pụtara ìhè na ihe eji arụ ọrụ n’ime ihe nkiri polyimide, a na-amụ mmetụta nke ntinye acid dị iche iche na oge ọgwụgwọ kwekọrọ. Mgbe ọgwụgwọ elu ahụ gasịrị, a na-emetụta arụmọrụ adhesion nke ihe nkiri polyimide, na nsonaazụ ngwa nke mgbanwe elu nke ihe nkiri polyimide bụ ndị a:

1. N’ebe a na-emepụta ọsọ ọsọ ugbu a, na-agbanwe ntinye acid-base enweghị mmetụta doro anya na ihe eji arụ ọrụ nke ihe nkiri polyimide mgbe ọgwụgwọ gasịrị.

2. Enwere ike ịhụ site na njirimara nke microscope atomic Force na ihe siri ike nke ihe nkiri polyimide na-abawanye nke ukwuu mgbe corrosion acid-base.

3. Mgbe ọgwụgwọ acid-base gasịrị, n’okpuru otu ntinye acid-base, ike peel nke PI na-abawanye na mgbatị nke oge ọgwụgwọ; N’otu ọsọ ụgbọ ala ahụ, ike peeling na-abawanye site na 0.9Kgf / cm na mmụba nke ntinye acid-base ruo 1.5Kgf / cm.

4. A na-eme ka ịdị ọcha nke akpụkpọ ahụ PI dịkwuo mma, nke na-edozi àgwà na mmepụta ihe na-emepụta ihe na-akpata site na nsị ndị ahịa ala.
