Rubber Industry: Used As A Reinforcing Agent, Activator, And Vulcanization Accelerator Zinc Oxide

Basic introduction of zinc oxide

Zinc oxide (ZnO) is an inorganic compound consisting of one zinc atom and one oxygen atom. It usually exists in the form of white to light yellow powder, is non-toxic and tasteless, and is difficult to dissolve in water and organic solvents, but soluble in acids and strong bases. Zinc oxide has high thermal and chemical stability, with a melting point of about 1975°C and a boiling point of up to 2360°C. Its crystal structure is diverse, the most common of which is the hexagonal wurtzite structure, which gives zinc oxide excellent electrical, optical and piezoelectric properties. Zinc oxide is widely used in industry, medicine and scientific research due to its versatility.

Zinc Oxide Parameters

Calculation process of relative molecular mass of zinc oxide

The relative molecular mass of zinc oxide (ZnO) can be calculated by simple addition. The atomic mass of zinc is about 65.38 and the atomic mass of oxygen is about 16.00, so the relative molecular mass of zinc oxide is 65.38 + 16.00 = 81.38. In practical applications, this value is usually rounded to 81.39. This calculation process shows how to deduce the relative molecular mass of a compound from the relative atomic mass of an atom, which is one of the basic skills in chemical calculations.

Application scenarios of relative molecular mass of zinc oxide

Due to its unique physical and chemical properties, zinc oxide is widely used in many fields. In the rubber industry, zinc oxide is often used as a reinforcing agent and activator to improve the corrosion resistance, tear resistance and elasticity of rubber. Zinc oxide also plays an important role in products such as plastics, ceramics, glass, cement, rubber, lubricants, paints, ointments, adhesives, caulking materials, pigments, food, batteries, ferrite materials and flame retardants. In addition, zinc oxide can also be used as an abrasive for toothpaste. Its mild grinding action can effectively remove dirt and plaque on the surface of teeth while protecting tooth enamel from damage. In the medical field, zinc oxide can be used to make ointments, zinc pastes, adhesive plasters, etc., which have antibacterial and anti-ultraviolet properties.

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.
