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.

Product Advantages

• Effective UV Defense: Zinc Oxide ranks among the most efficient physical sun blockers, delivering reliable broad‑spectrum UV shielding.
• Antibacterial & Anti-Inflammatory: It alleviates skin irritation and supports tissue repair, and is widely formulated in acne care products, eczema ointments and wound healing preparations.
• Eco-Friendly: As a naturally derived and biodegradable raw material, Zinc Oxide complies with green chemistry principles and supports sustainable product development.
• High Stability: Resistant to chemical breakdown and temperature variations, it exhibits outstanding performance for diverse industrial uses.
• Safe and Non-Toxic: With non-irritating characteristics, it can be safely applied in many end products, especially formulations tailored for sensitive skin.

Applications

Production Process

• Raw Material Selection The main feedstocks for zinc oxide manufacturing include zinc ores (e.g., sphalerite) and metallic zinc.
• Roasting Process Metallic zinc undergoes high-temperature reaction with oxygen to generate zinc oxide. Precise control over temperature and oxygen flow is implemented to obtain target purity and particle size.
• Grinding & Screening Following roasting, the calcined zinc oxide is milled into fine powder and screened to guarantee consistent particle size distribution.
• Purification Extra purification procedures may be adopted to eliminate impurities and upgrade the product purity as required.
• Quality Inspection & Packaging Finished zinc oxide is subject to comprehensive tests covering particle size, purity and UV absorption performance. Products that meet all specifications will be packaged for delivery.

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

Thanks to its wide bandgap and high exciton binding energy, ZnO exhibits excellent room-temperature luminescence. Its wurtzite hexagonal crystalline structure brings superior electrical, optical and piezoelectric properties. These inherent characteristics support ZnO’s wide-ranging use in various sectors.
