Codsiga

1. Isku-darka alaabada guud ee polyimide (PI) ee waxqabadka sare leh

Kani waa codsiga ugu caadiga ah uguna muhiimsan ee BPADA. BPADA waxaa lagu dhejiyay polycondensed oo leh monomers-ka diamine ee caadiga ah sida 4,4' -diaminodiphenyl ether (ODA) si loo sameeyo polyimide oo isku daraya "iska caabbinta kulaylka iyo fududaynta socodsiinta". Noocan walxaha PI, sababtoo ah joogitaanka xidhmooyinka ether iyo kooxaha isopropyl ee qaab-dhismeedkeeda molecular, waxay haysaa iska caabbinta heerkulka sare ee PI (heerkulka adeegga muddada-dheer 180-220℃). BPADA sidoo kale way fududahay in laga sameeyo filimaan, saxanno, iwm. marka loo eego PI-ga caadiga ah, waxaana badanaa lagu dabaqaa:

1) Qaybaha dahaarka aasaasiga ah ee qaybta elektarooniga: Filimka salka iyo filimka daboolka ah ee lagu sameeyo looxyada wareegga daabacan ee dabacsan (FPC), iyo sidoo kale warqad dahaar/dahaar oo heerkul sare u adkaysta oo loogu talagalay matoorada iyo transformers-ka, si loo daboolo shuruudaha "yareynta + iska caabbinta heerkulka" ee qaybaha elektarooniga ah, sida ilaalinta dahaarka gudaha ee qalabka elektarooniga macaamiisha iyo matoorada warshadaha.

2) Qaybaha guud ee u adkaysta heerkulka sare ee warshadaha: Waxaa loo sameeyay saxanno iyo tuubooyin PI ah, waxaana loo isticmaalaa biraha u adkaysta heerkulka sare ee ku wareegsan matoorada baabuurta iyo qaybaha gudaha ee u adkaysta kulaylka ee qalabka guryaha (sida foornooyinka iyo foornada microwave-ka). Waxay u adkaysan karaan heerkulka ka sarreeya 150℃ muddo dheer, waxayna u adkaystaan gabowga iyo dildilaaca.

2. Wax ka beddel resin-ka caadiga ah si kor loogu qaado waxqabadka

Wax ka beddelka resin-ka caadiga ah, BPADA, oo ah "monomer xoojinaya kulaylka", ayaa si caadi ah loo isticmaalaa si loo wanaajiyo waxqabadka resin-ka epoxy iyo resin-ka phenolic iyo in la ballaariyo xaaladaha codsigooda:

1) Wax ka beddelka resin-ka Epoxy: Marka lagu daro resin-ka epoxy-ga caadiga ah, BPADA waxay xoojisaa iska caabbinta heerkulka sare ee resin-ka (kordhinta iska caabbinta heerkulka muddada dheer ee resin-ka la daaweeyay laga bilaabo 120℃ ilaa in ka badan 180℃), waxaana loo isticmaalaa in lagu xidho alwaaxyada ugu muhiimsan ee daabyada dabaysha iyo dahaarka dahaarka fiilooyinka danab-sare leh, iyadoo la buuxinayo shuruudaha isticmaalka muddada-dheer ee goobaha bannaanka ama warshadaha.

2) Alaabada ceeriin ee aasaasiga ah ee dahaarka/xabagta u adkaysta heerkulka sare: Iyada oo ah qayb isku xidha dahaarka iyo xabagta, BPADA waxaa lagu daray resins phenolic iyo resins silicone si loo soo saaro dahaar u adkaysta heerkulka sare ee qalabka warshadaha (sida dahaarka ka hortagga daxalka iyo dahaarka kulaylka u adkaysta ee derbiyada gudaha ee kuleyliyaha iyo dhuumaha), iyo dhejisyo u adkaysta heerkulka sare ee ku bogsada heerkulka qolka biraha iyo dhoobada. Kuwaas waxaa badanaa loo isticmaalaa ilaalinta iyo isku xidhka qalabka farsamada iyo kiimikada.
