All of our products comply with international quality standards and are greatly appreciated in a variety of different markets throughout the world.Next, let's take a look at the two production methods of zinc oxide:
1. Direct method:
The production method of direct zinc oxide is to use waste ash to remove impurities through impurity removal equipment to obtain qualified zinc ash, then add qualified zinc ash to coal and lime according to technical requirements, mix and crush, and the crushed materials are pressed into balls with a briquette machine, and the crushed The good zinc-containing briquettes are piled up and dried; the dried briquettes are smelted in a zinc oxide furnace, and after reduction, oxidation, and cooling, they are collected to obtain Zinc Oxide products.[China Industrial Chain]Upstream Zinc Oxide and Zinc Ash. The downstream direct process zinc oxide is used in the production of ceramics, glass, plastics, cement products, synthetic rubber, lubricants, paints, ointments, adhesives, sealants, pigments, food, batteries, flame retardants and other products.
2. Indirect method reaction equation: 2Zn+O2=2ZnO
The manufacturing method of Indirect Zinc Oxide is as follows: the zinc ingot produced by electrolysis is placed in a high-temperature-resistant crucible, heated to 600-700°C and melted, then evaporated at a temperature higher than 1000°C to form zinc vapor, and the vapor is absorbed by oxygen in the air. Oxidation produces zinc oxide. This oxidation process emits a bright light and is accompanied by a decrease in temperature. The zinc oxide particles are then collected by a cooling conveyor tube in a dust collection chamber. Cyclone separation, the fine particles are captured with a cloth bag, That is, the finished product of White Powder Indirect Method Zinc Oxide is obtained.
This synthesis method was popularized by the Frenchman LeClaire in 1844, so this method is also called the French method. The product obtained by this method is generally zinc oxide particles with an average size of 0.1 to 10 microns. By weight, most of the world's zinc oxide is produced by this method.
