Zinc oxide What are the production methods and reagents? Zinc oxide As a filler material and other products, the production methods are diverse. This is due to significant advancements in science and technology, with more and more manufacturers using different methods to obtain this type of product. Market supply is stable. What are the production methods of reagent-grade zinc oxide in the industry?

1. Direct method, reagents Zinc oxide The production method utilizes waste ash, removing impurities through impurity removal equipment to obtain qualified zinc ash. The qualified zinc ash, coal, and lime are added according to technical development requirements and formulations, mixed, and crushed. The crushed materials are pressed into balls using a coal briquetting machine. The pressed zinc-containing briquettes are stacked and dried. The dried briquettes are then smelted using a zinc oxide furnace, and the reduced and oxidized products are collected and analyzed through a cooling system to obtain reagent-grade zinc oxide with improved quality and guaranteed quality as the product.

2. Indirect method: In the electrolysis method of silicon ingots placed in a high-temperature crucible, heating to melting evaporates zinc vapor at a higher temperature. The vapor is oxidized by oxygen in the air to form zinc oxide. The oxidation process involves bringing the material to a predetermined temperature, followed by a temperature decrease. The reagent-grade zinc oxide particles are collected in a dust collection chamber separated from the cooling transfer pipe via a cyclone separator, along with captured particulates (e.g., in bags), to obtain the zinc oxide product.

3. Zinc oxide What are the production methods? Wet method: Zinc ash reacts with sulfuric acid to produce zinc sulfate. This is reacted separately with sodium carbonate and ammonia water to produce zinc carbonate and zinc hydroxide, which are used as raw materials to produce reagent-grade zinc oxide. This method is considered a relatively systematic and common production management method by reagent-grade zinc oxide manufacturers. This method has relatively low production technical difficulty, and relatively little research has been done on bottleneck analysis issues during the company's production and development process. The properties, physical properties, and purity of reagent-grade zinc oxide produced by different methods will affect its performance. The products generally do not weaken their working ability during later use. However, different single production methods and purities will have some differences. It is necessary to choose a suitable method according to the actual situation.
