Xabagta phenolicwaa maaddo polymer synthetic ah oo ay samaysay uumi phenols (sida phenol) iyo aldehydes (sida formaldehyde) oo hoos yimaada aashitada ama catalysis salka. Waxay leedahay iska caabin kulayl oo heer sare ah, dahaarka iyo xoogga farsamada waxaana loo adeegsadaa koronto, baabuur, hawada hawada iyo meelo kale.
Resin Phenolic (Phenolic Resin) waa resin synthetic ah oo la warshadeeyay. Waxaa lagu sameeyaa falcelinta uumiga ee phenol ama asalkiisa (sida Cresol, xylenol) iyo formaldehyde. Marka loo eego nooca kicinta (ashito ama alkaline) iyo saamiga alaabta ceeriin, waxa loo qaybin karaa laba qaybood: thermoplastic iyo thermosetting. ?
Astaamaha ugu muhiimsan guryaha:
1. Caadiyan waa mid adag oo hufan oo aan midab lahayn ama huruud ah. Alaabooyinka ganacsi ee la heli karo waxay inta badan ku daraan midabyo si ay u soo bandhigaan midabyo kala duwan. ?
2. Waxay leedahay iska caabin kulayl oo aad u fiican, waxaana loo isticmaali karaa waqti dheer at 180 ℃. Waxay samaysaa heerkul sare oo kaarboon ah oo haraaga ah (qiyaastii 50%) heerkul sarreeya. ?
3. Astaamaha shaqada:
Dahaar koronto oo heer sare ah, dib u dhac olol ah (looma baahna in lagu daro olol dib u dhigista) iyo xasilloonida cabbirka. ?
Waxay leedahay awood farsamo sare leh, laakiin way jajaban tahay oo way fududahay in la nuugo qoyaanka. ?
4. Kala-soocidda iyo qaab-dhismeedka Thermoplastic phenolic resin : Qaab dhismeedka toosan, wuxuu u baahan yahay in lagu daro wakiilka daawaynta (sida hexamethylenetetramine) si loo isku xiro loona daweeyo. ?
5. Heerkulbeeggaphenol-formaldehyde resin: Qaab dhismeedka isku xidhka shabakada, waxa lagu daawayn karaa kulaylinta, waxa uu leeyahay kulaylka adkaysi badan iyo xoog farsamo
Xabagta phenolic waxaa inta badan loo isticmaalaa in lagu soo saaro balaastikada kala duwan, dahaarka, xabagta iyo fiilooyinka synthetic.
