Abstract

The objective of this research is to study the controllable factors affecting the lacquer quality and to find out the optimum conditions of the controllable factors by Central Composite Rotatable Design. For the crushing in Lacquer process, three controllable factors such as the quantity of solvent (x1), cooling temperature (x2), and the specific time frame of crushing (x3) were investigated. Response factor was the smoothness of lacquer surface. The relationship between response and controllable factors was determined. From the results, it was found that the optimal controllable factors were as followed: solvent of 95.59 kilograms, the cooling water temperature of 14.7 °C, and specific crushing time of 23.25 minutes. These controllable factors led to obtain the optimum smoothness of lacquer surface of 6.5 Hexman. The validation of the experiment by using such optimum setting of controllable factors from the Central Composite Rotatable Design, resulted in the 4.6% error of the lacquer surface smoothness.
