      The traditional process of wax processing adopts static settling method, and wax material often occurs with a concave, flow lines, apparent bubbles, and the difficulty in cleaning the pasted knife and wax crumbs during trimming of the wax, which seriously affects the quality of the product. In order to solve these problems, the effect of moisture content on the synthetic properties of waxes and the forming quality of wax materials are studied by using the 162 medium-temperature wax. The result shows that as the water content increases, the surface quality of the wax tends to increase and the wax is full. When wax material moisture content is controlled between 4%~7%, wax line contraction, sag and surface flow lines are not so apparent, the comprehensive usability is good, wax doesn't stick on the knife during trimming of the wax, and wax crumbs are easy to clean. The results show that the water content of the wax can be controlled and monitored by the method of observing color through making standard sample for comparison. This method is simple, convenient and feasible, and can be used in the monitoring of moisture content in wax production.
