What are the production methods of reagent zinc oxide
Release date:2021-08-18

Reagent zinc oxide is used as a filling material for many products. Its production methods are diverse, and the production methods are generally less difficult. In particular, the development of science and technology has greatly improved its production level, precisely because more and more manufacturers have adopted different methods. This kind of product is produced by the method, so its market supply also tends to be stable, so what production methods are there for the better reagent zinc oxide in the industry?

1. Direct method

The direct method reagent zinc oxide production method is to use waste ash to remove impurities through impurity removal equipment to obtain qualified zinc ash, then add the qualified zinc ash to coal and lime according to the technical requirements, mix and crush, and press the crushed material with a briquette machine. The compressed zinc-containing briquettes are stacked and air-dried. The air-dried briquettes are smelted in a zinc oxide furnace. After reduction, oxidation, and cooling are collected to obtain a quality-guaranteed reagent zinc oxide product.

2. Indirect method

The zinc ingot produced by the electrolysis method is placed in a high temperature crucible, heated to a specified temperature and melted, and evaporates at a higher temperature to form zinc vapor. The vapor is oxidized by oxygen in the air to produce zinc oxide. This oxidation process will emit The shining light is accompanied by a decrease in temperature, and then the reagent zinc oxide particles are collected in a dust collection chamber through a cooling transfer tube and separated by a cyclone, and the fine particles are trapped in a cloth bag to obtain a finished zinc oxide product.

3. Wet method

Zinc ash is reacted with sulfuric acid to generate zinc sulfate, which is then reacted with sodium carbonate and ammonia water respectively to prepare reagent zinc oxide using the prepared zinc carbonate and zinc hydroxide as raw materials. This method is called a more common production method by reagent zinc oxide manufacturers, because the production difficulty of this method is relatively small, and there are relatively few bottlenecks in the production process.
