Resin fenolic ahwaa walax polymer ah oo macmal ah oo ay samaysay isku-darka phenols (sida phenol) iyo aldehydes (sida formaldehyde) iyadoo la adeegsanayo aashitada ama saldhigga catalysis. Waxay leedahay iska caabin kulayl oo aad u fiican, dahaadh iyo xoog farsamo waxaana loo isticmaalaa meelaha korontada, baabuurta, hawada sare iyo meelaha kale.
Resinka phenolic (Resinka phenolic) waa resin macmal ah oo warshadaysan. Waxaa lagu sameeyaa falgalka isku-dhafka phenol ama waxyaabaha ka soo baxa (sida cresol, xylenol) iyo formaldehyde. Sida ku cad nooca kataliyaha (acidic ama alkaline) iyo saamiga walxaha ceeriin ah, waxaa loo qaybin karaa laba qaybood: thermoplastic iyo thermosetting.
Astaamaha ugu muhiimsan Sifooyinka Jireed:
1. Badanaa waa bunni aan midab lahayn ama midab huruud ah oo hufan. Badeecadaha ganacsi ahaan la heli karo badanaa waxay ku daraan midabyo kala duwan si ay u soo bandhigaan midabyo kala duwan.
2. Waxay leedahay iska caabin kulayl oo aad u fiican waxaana loo isticmaali karaa muddo dheer heerkul ah 180℃. Waxay samaysaa heer sare oo kaarboon haraaga ah (qiyaastii 50%) heerkulka sare.
3. Astaamaha shaqaynta:
Dahaarka korontada oo aad u fiican, daahinta dabka (looma baahna in lagu daro daahyada dabka) iyo xasilloonida cabbirka.
Waxay leedahay awood farsamo oo sare, laakiin waa jilicsan tahay oo si fudud loo nuugi karo qoyaanka.
4. Kala-soocidda iyo qaab-dhismeedka Resin phenolic Thermoplastic: Qaab-dhismeedka toosan, wuxuu u baahan yahay in lagu daro wakiilka bogsiinta (sida hexamethylenetetramine) si loo isku xidho oo loo bogsiiyo.
5. Heerkulka dejisaResin Phenol-formaldehydeQaab-dhismeedka isku-xidhka shabakadda, waxaa lagu daaweyn karaa kuleylinta, wuxuu leeyahay iska caabin kuleyl oo sarreeya iyo xoog farsamo
Resin-ka phenolic waxaa inta badan loo isticmaalaa in lagu sameeyo balaastigyo kala duwan, dahaadh, dhejisyo iyo fiilooyin macmal ah.
