As a filling material for many products, zinc oxide has various production methods, and the difficulty of each method is generally low. Especially with the development of science and technology, its production level has been greatly improved. It is precisely because more and more manufacturers have produced this product through different methods that its market supply has become stable. So, what are the better production methods for zinc oxide reagents in the industry?

1、 Direct method

The direct method for producing zinc oxide is to use waste ash to remove impurities through impurity removal equipment to obtain qualified zinc ash. Then, the qualified zinc ash is added to coal and lime according to technical requirements, mixed and crushed. The crushed material is pressed into balls using a coal ball machine. The pressed zinc containing coal balls are stacked and dried, and the dried coal balls are smelted in a zinc oxide furnace. After reduction oxidation and cooling, the quality guaranteed reagent zinc oxide product is collected.

2、 Indirect method

The zinc ingot produced by electrolysis is placed in a high-temperature resistant crucible, heated to a specified temperature and melted. It evaporates at a higher temperature to form zinc vapor, which is oxidized by oxygen in the air to produce zinc oxide. This oxidation process emits a shiny light while accompanied by a decrease in temperature. Subsequently, the zinc oxide particles of the reagent are collected in a dust collection chamber through a cooling conveyor tube and separated by a cyclone. The fine particles are captured with a cloth bag to obtain the finished zinc oxide product.

3、 Wet process

Zinc sulfate is generated by reacting zinc ash with sulfuric acid, and then reacted separately with sodium carbonate and ammonia water to produce zinc oxide as a reagent, using the obtained zinc carbonate and zinc hydroxide as raw materials. This method is referred to as a relatively common production method by zinc oxide reagent manufacturers because its production difficulty is relatively low and there are relatively few bottleneck issues in the production process.
