Zinc Oxide for Healthcare Plastics Coatings Paints Optoelectronics

Zinc Oxide Product Overview

Product Overview

Zinc Oxide (ZnO) is a multi-functional inorganic compound, normally presented as white powder. It has extensive uses in cosmetics, healthcare products, rubber, coatings, electronics and other industries. Featuring excellent UV absorption, antibacterial activity, conductivity and chemical stability, ZnO acts as a vital raw material for countless products. It delivers UV protection, restrains bacterial growth, and strengthens the durability of final products.

Key Product Characteristics

• UV Protection: Zinc Oxide effectively blocks both UVA and UVB radiation to deliver robust UV shielding. As a physical sunscreen agent, it forms a protective film over the skin surface.
• Antibacterial Properties: ZnO suppresses bacterial proliferation and provides soothing anti‑inflammatory benefits, which makes it well-suited for formulations targeting various skin concerns.
• Chemical Stability: Chemically inert in nature, Zinc Oxide maintains stable performance across diverse environments and will not react with most materials.
• Thermal Stability: Zinc Oxide retains its structural stability under high temperatures up to 600°C, rendering it applicable for high-temperature working scenarios.
• Non-Toxic and Safe: This raw material is non-toxic and gentle to skin. It can be incorporated into baby care products and formulations designed for sensitive skin.
• Semiconductor Properties Thanks to its conductivity and intrinsic semiconductor characteristics, Zinc Oxide is widely adopted in electronics, sensors and optoelectronic components.

• Antibacterial & Anti-Inflammatory: It relieves skin irritation and aids skin recovery, widely used in acne treatments, eczema creams and wound care items.
• Eco-Friendly: This natural biodegradable material fits green chemistry requirements and supports sustainable manufacturing.
• High Stability: It withstands chemical degradation and temperature changes, ideal for multiple industrial applications.
• Safe and Non-Toxic: Non-irritating to skin, it is safe for various products, especially formulations for sensitive skin.

Applications

• Cosmetics & Personal Care: Used in sunscreens, day creams, BB creams, cleansers, and facial masks for its UV-blocking properties and skin protection.
• Healthcare Products: Zinc Oxide is a key ingredient in anti-inflammatory ointments, calamine lotion, and treatments for acne, eczema, and minor skin irritations.
• Rubber & Plastics: It is used as a vulcanizing agent in rubber production, improving strength, wear resistance, and aging properties in tires, footwear, and industrial rubber products.
• Coatings & Paints: In the coatings industry, Zinc Oxide serves as a white pigment with excellent coverage, durability, and UV resistance, used in paints, anti-corrosion coatings, and waterproofing products.
• Electronics & Optoelectronics: As a semiconductor, Zinc Oxide is applied in solar cells, sensors, LEDs, and other optical and electronic devices for enhanced efficiency and stability.

Production Process

• Raw Material Selection: The primary raw materials for Zinc Oxide production are zinc ores (such as sphalerite) or zinc metal.
• Roasting Process: Zinc metal is heated to high temperatures to react with oxygen and form Zinc Oxide. Temperature and oxygen flow are carefully controlled to achieve the desired purity and particle size.
• Grinding & Screening: After roasting, the Zinc Oxide powder is ground into a fine powder and screened to ensure uniform particle distribution.
• Purification: In some cases, additional purification steps are taken to remove impurities and enhance the purity of Zinc Oxide.
• Quality Inspection & Packaging: Zinc Oxide is thoroughly tested for particle size, purity, and UV absorption properties. Upon passing quality checks, the product is packaged and ready 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

ZnO's large bandgap and exciton binding energy contribute to its excellent room-temperature luminescent properties. Meanwhile, its wurtzite hexagonal crystalline structure grants ZnO good electrical, optical, and piezoelectric properties. These theoretical foundations provide a scientific basis for ZnO's applications in multiple fields.

Packaging and Storage

ZnO products are typically packaged in woven bags or plastic drums, ensuring safety and stability during transportation and storage. Store in a dry, well-ventilated, dark place, avoiding contact with moisture, high temperatures, and flammable materials.

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.
