The invention discloses an acceptance method for a roll coater working roll. A preset appearance quality interval and a preset structure parameter interval are established, the appearance quality andthe structure parameter of the working roll are detected, the detected appearance quality of the working roll and the preset appearance quality interval are compared, the detected structure parameteris compared with the preset structure parameter interval so as to judge whether the working roll is a qualified product or not, and therefore, whether the working roll is accepted or not is determined. By use of the acceptance method for the roll coater working roll, the acceptance process of the roll coater working roll can be specified, and the quality of the working roll is guaranteed. When theworking roll is applied to the roll coater to carry out passivation treatment on galvanized strip steel, passivation quality can be stabilized, and in addition, a formed passivation film has even thickness. In addition, the quality of the working roll can guarantee that the faults of the roll coater can be reduced, the maintenance cost of the roll coater is lowered, the interference of personnelis reduced, and the safety of the personnel is guaranteed.
