Baakaynta iyo kaydinta
jajabka/budada: 20kg/bac, 25kg/bac, Lagu soo buuxiyay bac tolan, ama bac warqad Kraft ah oo gudaha ku leh caag. Resin waa in lagu kaydiyaa meel qabow, engegan oo hawo fiican leh oo ka fog isha kulaylka si looga fogaado qoyaanka iyo qoyaanka. Midabkeedu wuxuu noqon doonaa mugdi marka la kaydiyo wakhtiga, taas oo aan wax saameyn ah ku yeelan doonin heerka resinka.
budada bakelite iyo budada resin phenolic oo kala duwan.
Waa maxay farqiga u dhexeeya budada resin phenolic iyo budada bakelite? Magaca kiimikada ee bakelite waa balaastig phenolic ah, kaas oo ah noocii ugu horreeyay ee balaastiig ah oo la geliyo wax soo saarka warshadaha. Xabagta phenolic waxaa lagu diyaarin karaa polycondensation of phenols iyo aldehyde marka ay joogaan kiciyayaasha acidic ama alkaline. Budada Bakelite waxa lagu helaa iyada oo si buuxda loo qaso resin phenolic budo alwaax ah, budada talc (filler), urotropine (wakiilka daawada), stearic acid (lubricant), midabka, iwm, iyo kuleylinta iyo qaso qasaha. Budada Bakelite waa la kululeeyay oo lagu riixay caaryada si loo helo badeecooyin caag ah oo heerkulbeeg ah.
Bakelite waxay leedahay awood farsamo oo sare, dahaarka wanaagsan, adkaysiga kulaylka iyo iska caabinta daxalka .
