Zinc Oxide Product Introduction

Basic properties of zinc oxide

Zinc oxide (ZnO), commonly known as zinc white, is a white solid that is difficult to dissolve in water but soluble in acids and strong bases. It has high chemical stability and is not easy to decompose at high temperatures. These properties make zinc oxide widely used in many fields

Chemical properties

Chemical stability: Zinc oxide has high chemical stability and can remain stable in harsh environments such as high temperature, high pressure, strong acid, and strong alkali. This stability makes zinc oxide widely used in many industrial fields.
Amphoteric oxide properties: Zinc oxide is an amphoteric oxide that can react with both acid and alkali.
Catalytic effect: Zinc oxide has a certain catalytic activity and can be used as a catalyst to participate in various chemical reactions and accelerate the reaction process.

Overview of rubber uses:
①Active zinc oxide is mainly used as a reinforcing agent for rubber to make the rubber have good corrosion resistance, tear resistance, elasticity and elongation.
②It is used as an accelerator for rubber vulcanization process. It is a multifunctional rubber compounding agent, mainly used as a vulcanization activator and reinforcing agent for natural rubber, synthetic rubber and latex.
③When used as a vulcanization activator, it is evenly distributed in the rubber material, has a large contact area with hydrogen sulfide, and has a greater opportunity for interfacial reaction. In addition, this active zinc oxide product has a catalytic effect of active substances, which makes the conversion rate of zinc oxide to zinc sulfide high.
④As a vulcanization oxidant, its function is to enhance the activity of the accelerator, reduce the amount of accelerator, and shorten the vulcanization cycle.
⑤It can accelerate the vulcanization speed, improve the thermal conductivity of the vulcanized rubber, and make the vulcanization more thorough.
⑥In the rubber industry, especially in the production of transparent rubber products, active zinc oxide is an excellent vulcanization active agent.

6. Agriculture: Serves as a micronutrient in fertilizers and animal feed additives.

Production Technology

The direct method, also known as the French process, involves the following steps:
1. Raw Material Selection: High-purity zinc materials such as zinc ore or zinc scrap are used.
2. Smelting: Zinc is heated and vaporized.
3. Oxidation: Zinc vapor reacts with oxygen in a controlled environment to produce fine zinc oxide powder.
4. Collection and Processing: The resulting ZnO is collected, filtered, and classified to ensure quality and uniformity.

Theory

The production of Zinc Oxide via the direct method is based on the principle of oxidation of metallic zinc in the presence of oxygen. The chemical reaction is:
2Zn + O₂ → 2ZnO
This process ensures the formation of high-purity zinc oxide with uniform particle size.
