Embodiment Construction
[0031] In conjunction with the accompanying drawings, the following examples of the present invention are given, but the present invention is not limited to the following examples.
[0032] The production and calcination process of zinc oxide described in this embodiment is to place zinc raw materials in the oxidation furnace, heat the oxidation furnace through external heat, and close the external heat after the temperature in the oxidation furnace reaches above 900 ° C. This temperature can make the oxidation furnace The zinc raw material inside reacts with oxygen. The negative pressure continuous production method is adopted. After the zinc raw material and oxygen are fully mixed and reacted in the oxidation furnace, the zinc raw material and oxygen undergo a redox reaction to generate zinc oxide and release a large amount of heat to burn the raw material to form a gaseous raw material. Zinc oxide is obtained after cooling process and powder collecting process. In order to...
