Zinc Oxide for Healthcare Plastics Coatings Paints Optoelectronics

Zinc Oxide Product Overview

Product Overview

Zinc Oxide, commonly abbreviated as ZnO, is a highly versatile inorganic chemical compound. It generally appears as a fine white powder at room temperature and boasts wide-ranging applications spanning numerous industrial sectors. Major application fields include cosmetics, healthcare products, rubber manufacturing, industrial coatings, electronic components, and many other industries. Valued for its outstanding ultraviolet absorption capacity, reliable antibacterial performance, electrical conductivity and superior chemical stability, zinc oxide serves as an essential functional ingredient in a large array of end products. It can effectively shield substrates and human skin from harmful UV radiation, suppress the reproduction of bacteria, and significantly improve the long-term durability and service life of finished goods.

Applications

Production Process

• Raw Material Selection Zinc oxide is mainly produced from zinc ores (such as sphalerite) or metallic zinc.
• Roasting Process Metallic zinc reacts with oxygen under high heat to form zinc oxide. Temperature and oxygen flow are closely controlled to reach required purity and particle size.
• Grinding & Screening After roasting, zinc oxide is finely ground and screened to ensure even particle distribution.
• Purification Additional purification steps can be applied to remove impurities and boost product purity.
• Quality Inspection & Packaging We test finished ZnO for particle size, purity and UV absorption. Qualified goods are packaged and prepared for shipment.

Process Flow

Zinc oxide production comprises batching, feeding, rotary kiln, slag water quenching, oxidation cooling, dust collection and bagging, as well as flue gas desulfurization systems. The rotary kiln acts as the core equipment; ZnO is produced inside it through high-temperature oxidative roasting. According to raw materials and process types, manufacturing methods fall into four categories: direct, indirect, acid and ammonia processes.

Theory

Zinc oxide features a wide bandgap and high exciton binding energy, which endows it with outstanding luminescence performance at room temperature. Its wurtzite hexagonal crystal structure also delivers favorable electrical, optical and piezoelectric characteristics. Such intrinsic material properties lay the scientific foundation for zinc oxide’s broad applications across diverse industries.

Packaging and Storage

ZnO products are commonly packed in woven bags or plastic drums to guarantee safety and stability throughout transportation and storage. Keep the material in a dry, well-ventilated and shaded storage area. Avoid exposure to moisture, excessive heat and combustible substances.

Precautions

1. Personal Protection: Wear protective masks, gloves and goggles when producing or handling ZnO to avoid inhalation, skin and eye contact.
2. Fire Prevention Measures: ZnO itself is non-flammable, but store it separate from ignition sources and flammables to reduce fire risks.
3. Spill Handling: For ZnO spills, cover with sand or inert materials right away, collect the material for safe disposal and prevent environmental contamination.
