Indlela yokuphucula ukusebenza kokunamathela kwifilimu ye-polyimide

Ifilimu yePolyimide yimveliso yefilimu ethandwa kakhulu ngoku, enoluhlu olubanzi lwezicelo kunye nokusebenza okugqwesileyo. Nangona kunjalo, ngexesha lokusetyenziswa, abanye abathengi kunye nabahlobo baya kudibana neengxaki ngokusebenza kwayo kokubambelela kumphezulu. Ke, ungawuphucula njani umsebenzi wokuncamathelisa umphezulu wefilimu ye-polyimide? Abavelisi beengcali baya kunika impendulo engezantsi, yiza kwaye ubone.

Ifilimu yePolyimide (PI) yimathiriyeli ekhethekileyo yokwenziwa kwepolymer eneempawu ezibalaseleyo zomzimba kunye noomatshini kunye nozinzo olubalaseleyo lombane kunye neekhemikhali. Isetyenziswa ngokubanzi kwi-aerospace, i-insulation yombane, i-microelectronics kunye namanye amashishini (njenge-dielectric spacer, umaleko okhuselayo, kunye nesiseko se-foil yensimbi). Ngenxa yokuba ifilimu ye-PI inomgangatho ogudileyo, umsebenzi ophantsi weekhemikhali, kunye nokunamathela kakubi kwi-foil yensimbi (i-aluminium foil, i-copper foil, njl.). ), umphezulu wefilimu ye-PI kufuneka iphathwe okanye iguqulwe ukuze kuphuculwe ukunamathela kwendawo ye-PI.

Okwangoku, kuzo zonke iindlela zonyango kunye nokuguqulwa kwefilimu ye-polyimide, ngenxa yenkqubo kunye neendleko, unyango lwe-acid-base lufundwe ngokubanzi. Amanye amaxwebhu baye babika ukuba olu hlobo lokuphucula ukumanzisa kunye nendlela yokubambelela, kodwa umsebenzi oyintloko weemveliso zoshishino emva kokuba unyango luswele iingxelo ezifanelekileyo kunye nengqalelo.

Ngokuphatha umphezulu wefilimu ye-polyimide kunye nesisombululo se-oxalic acid, i-sodium hydroxide kunye namanzi anetyuwa, ngaphandle kokuchaphazela umgangatho obonakalayo kunye neempawu zangaphakathi zangaphakathi zefilimu ye-polyimide, imiphumo ye-acid-base-based concentrations kunye nexesha elihambelanayo lonyango lifundwe. Emva konyango olungaphezulu, ukusebenza kokubambelela kwefilimu ye-polyimide kuchaphazeleka, kwaye iziphumo zesicelo sokuguqulwa komphezulu wefilimu ye-polyimide zimi ngolu hlobo lulandelayo:

1. Kwisantya sokuvelisa ngoku, ukutshintsha i-acid-base-concentration ayinayo impembelelo ecacileyo kwiipropati zemishini yefilimu ye-polyimide emva kokunyanga.

2. Inokubonwa kwi- characterization ye-atomic force microscope ukuba uburhabaxa befilimu ye-polyimide bunyuswe kakhulu emva kokubola kwe-acid-base.

3. Emva kokunyangwa kwe-acid-base, phantsi kwe-acid-base concentration, amandla e-peel e-PI ayanda kunye nokwandiswa kwexesha lonyango; ngesantya esifanayo sesithuthi, amandla okukhupha ayanda ukusuka kwi-0.9Kgf / cm kunye nokunyuka kwe-acid-base concentration ukuya kwi-1.5Kgf / cm.

4. Ucoceko lwe-PI membrane surface luphuculwe kakhulu, olusombulula umgangatho kunye nokungahambi kakuhle kwemveliso okubangelwa yinkunkuma yabathengi abasezantsi.
