Zinc Oxide for Healthcare Plastics Coatings Paints Optoelectronics

Zinc Oxide Product Overview

Product Overview

Zinc oxide (ZnO) is a multifunctional inorganic compound that typically appears as a white powder. It is widely used in cosmetics, healthcare products, rubber, coatings, electronics, and various other industries. Thanks to its excellent UV absorption, antibacterial activity, electrical conductivity, and chemical stability, ZnO serves as a key raw material for numerous products. It provides UV protection, inhibits bacterial growth, and enhances 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.

Product Advantages

• Effective UV Defense: Zinc Oxide is a top-performing physical sunblock that delivers broad-spectrum UV protection.
• 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: Thanks to its UV-blocking and skin-protecting effects, it is included in sunscreens, day creams, BB creams, cleansers, and facial masks.

Healthcare Products: Zinc oxide is an essential component of anti-inflammatory ointments, calamine lotion, and remedies for acne, eczema, and minor skin irritation.

Rubber & Plastics: In rubber manufacturing, it serves as a vulcanizing agent, enhancing the strength, wear resistance, and aging resistance of tires, footwear, and industrial rubber products.

Coatings & Paints: In the coatings sector, zinc oxide functions as a white pigment with outstanding coverage, durability, and UV resistance, and is therefore used in paints, anti-corrosion coatings, and waterproofing products.

Electronics & Optoelectronics: As a semiconductor, zinc oxide is used in solar cells, sensors, LEDs, and other optical and electronic devices to improve their efficiency and stability.

Production Process

Raw Material Selection: The main feedstocks used to produce Zinc Oxide are zinc ores, such as sphalerite, or zinc metal.

Roasting Process: Zinc metal is exposed to high temperatures so that it reacts with oxygen to produce Zinc Oxide. Both the temperature and the oxygen flow are precisely regulated to obtain the required purity and particle size.

Grinding & Screening: Following roasting, the Zinc Oxide powder is milled into a fine powder and then screened to guarantee a uniform particle distribution.

Purification: In certain cases, further purification procedures are carried out to eliminate impurities and increase the purity of the Zinc Oxide.

Quality Inspection & Packaging: The Zinc Oxide undergoes comprehensive testing for particle size, purity, and UV absorption characteristics. Once it passes quality checks, the product is packaged and prepared for shipment.

Process Flow

Zinc oxide manufacturing involves several stages, including batching, feeding, rotary kiln processing, slag water quenching, oxidation and cooling, dust collection and bagging, along with flue gas desulfurization systems. The rotary kiln serves as the core equipment, where ZnO is generated through high-temperature oxidative roasting. Depending on the raw materials used and the type of process employed, production methods can be classified into four categories: the 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.
