Tawada PCB tana nufin tawada da aka yi amfani da ita a cikin Allon da aka buga. a cikin buga kewaye hukumar tsarin masana’antu, bugun allo yana ɗaya daga cikin mahimman matakai masu mahimmanci. Don samun amincin haɓakar hoto, tawada dole ne ta kasance mai inganci. Ingancin tawada PCB ya dogara ne akan ko dabarun kimiyya ne, ci gaba ne kuma mai muhalli. Yana kunshe cikin:

Viscosity gajarta ne don ɗimbin ƙarfi. Yawanci ana nuna ɗimbin ɗabi’a azaman damuwar ruwa na kwararar ruwan da rabe -raben gudu ya raba a cikin layin da ke gudana, a cikin Si pas/SEC (Pa). S) ko millipas/sakan (mPa). S). A cikin samar da PCB yana nufin ruwa mai tawada da sojojin waje ke kora su.
