Weligaa ha u malayn in cajalad polyimide ay leedahay faa’iidooyinkan

Cajaladda Polyimide, oo sidoo kale loo yaqaan cajalad Kapton, oo caadi ahaan loo yaqaan cajalad farta dahabka ah, waxay ku salaysan tahay filimka polyimide, waxay isticmaashaa koolada cadaadiska silikoon ee laga keeno, waxayna isticmaashaa filimka polyimide substrate ahaan. Dhinac baa laga dahaadhay. Xabagta cadaadiska silikoonka ee waxqabadka leh, waxaa jira laba nooc oo maaddooyin ah, balaastiig hal dhinac ah oo fluorine ah oo sii daaya walxo isku dhafan ama aan isku dhafanayn.

Cajaladda KAPTON (cajalad heerkul sare leh, far dahab ah oo heerkul sare ah) waa nooc ka mid ah dahaarka u adkeysanaya cajalad koronto, oo lagu dahaadhay dhumucyo kala duwan oo cajalad polyimide ah (0.04-0.18) ayaa loo habeyn karaa iyadoo loo eegayo shuruudaha u adkeysiga macaamiisha. Filimka polyimide oo si gaar ah loo farsameeyay oo heerkulkiisu sarreeyo oo leh dahaarka u adkaysta, oo leh dahaar aad u fiican, xidho iska caabin ah, caabbinta aashitada iyo alkali, iska caabinta heerkulka sare ee 270 darajo / 30 daqiiqo, 180 digrii ayaa loo isticmaali karaa waqti dheer.

Faa’iidooyinka cajalad polyimide waxaa inta badan lagu soo koobay shan dhibcood: caabbinta kulaylka, caabbinta qoyaanka, xoogga dielectric, dareeraha iyo caabbinta kiimikada, iyo moldability.

1. Iska caabinta kulaylka sare: laba cajaladood oo polyimide ah oo lagu duuduubay laba lakab oo dhumucdiisu tahay 0.075mm laguna dahaadhay balaastiigga F46, kuwaas oo fiilooyinka magnetka leh lakabka fluoroplastic ee 0.025mm la isku maroojinayo, heerkul ah 264 ° C, wuxuu gaari karaa cimrigiisu waa 20,000 saacadood, kulaylka u adkaysta wuxuu gaari karaa 264°C. Maadaama heerkulkani uu ku dhow yahay barta dhalaalka ee lakabka fluoroplastic, heerkulka adagi waa 240 ° C oo kaliya.

2. U adkaysiga qoyaanka sare: Maadaama lakabka dahaadhka ahi uu labbis yahay oo aanay jirin godad fiiqan, ma noqon doonto mid gaaban oo wareeg ah marka la eego xaaladaha supermarket-ka. Waxa kale oo ay leedahay wax-qabad heersare ah ka dib marka lagu dhex geliyo biyaha 24 saacadood.

3. Awood dielectric sare ah: isticmaal 0.075mm dhumuc polyimide cajalad leh F46 caag ah, kaas oo dhumucda lakabka fluoroplastic waa 0.025mm, 52% ee silig magnet laded leh hal lakab, iyo danab burburay waa in ka badan 6Kv, kaas oo kaliya ma wanaajiso Heerka korantada ee adkeysiga u dhexeeya leexashada waa la wanaajiyay, heerka korantada caabbinta sidoo kale waa la wanaajiyay.

4. Kala-duwanaanta sare iyo caabbinta kiimikada: Tani waxaa lagu go’aamiyaa dabeecadda cajaladda polyimide iyo fluoroplastics, iyo sababtoo ah waxqabadka wanaagsan ee daboolka lakabka, kooraska naxaasta ah ma la xiriiri doono walxaha dibadda. Ma jiri doonto wax dhaawac ah oo soo gaara lakabka dahaadhka ee siligga dhaldhalaalka ah ee dareeruhu inta lagu jiro habka wax-miridda caadiga ah.

5. Qaab-dhismeedka wanaagsan: Cajaladda polyimide ee waxqabadka fidinta wanaagsan waxay ka dhigi kartaa isha siliga dahaaran ee qaabab kala duwan iyada oo aan dillaacin oo burburin lakabka daboolka; ma dhaawacmi doonto marka la foorarsado, gaar ahaan sanka qalloocan ee kaari gariiradda armature. Dildilaaca lakabka dahaarka ayaa dhici doona.
