Product Description

Industrial ZnO Oxide Zinc Sunscreen Powder Heat Resistant For Rubber Products

Zinc Oxide Introduction

Zinc oxide (ZnO), commonly known as zinc white, is an oxide of zinc. It is insoluble in water but soluble in acid and strong alkali. At high temperatures it appears yellow, turning white after cooling, and sublimates at 1800°C. The zinc oxide lattice is of ZnS type, with oxygen in the tetrahedron formed by zinc, and zinc in the tetrahedron of oxygen, with a coordination number of 4. As a strong ultraviolet absorber, it is widely used in industry as a reinforcing agent for rubber products, white pigment, plastic filler, paint colorant, and as the main component of emollients, ointments, and zinc pastes.

Production Methods Comparison

Zinc oxide production can be divided into three types according to its production method: indirect zinc oxide, direct zinc oxide, and active zinc oxide.

Direct zinc oxide is mostly made from zinc ore, zinc ash, and zinc concentrate. It is oxidized and roasted at high temperature then reduced to zinc vapor by coal. The vapor is oxidized with hot air to obtain zinc oxide. This process yields product purity between 75-95% with higher impurity content.
Indirect zinc oxide uses metal zinc ingot or zinc slag as raw material. Zinc is converted to vapor at 1000°C in a graphite crucible, then oxidized by air to produce zinc oxide particles collected after cooling. This method produces particles between 0.1-10 microns with purity of 99.5-99.7%.

Chemical Properties

Chemical stability: Remains stable in harsh environments including high temperature, pressure, strong acid, and strong alkali.
Amphoteric oxide properties: Can react with both acids and bases.
Catalytic effect: Exhibits catalytic activity to accelerate various chemical reactions.

Rubber Industry Applications

Acts as a reinforcing agent, providing corrosion resistance, tear resistance, elasticity and elongation
Functions as a vulcanization accelerator for natural rubber, synthetic rubber and latex
Enhances vulcanization activity, reducing accelerator amounts and shortening vulcanization cycles
Improves thermal conductivity for more thorough vulcanization
Essential for transparent rubber product production

Advantages

Superior Quality: Produced with advanced direct-method technology ensuring consistent quality and purity
Versatility: Suitable for rubber, ceramics, cosmetics and other industries
Environmentally Safe: Low heavy metal content and safe for diverse applications
Excellent Performance: Provides enhanced reinforcement, thermal stability and UV protection

Applications

Rubber Industry: Reinforcing agent, activator, and vulcanization accelerator
Ceramics: Improves whiteness, strength and thermal stability
Paints & Coatings: Pigment and anti-corrosion agent
Cosmetics: UV absorber in sunscreens and skincare products
Pharmaceuticals: Antiseptic and astringent in ointments
Agriculture: Micronutrient in fertilizers and animal feed additives

Production Technology

The direct method (French process) involves:

Selection of high-purity zinc materials
Smelting and vaporization of zinc
Oxidation of zinc vapor in controlled environment
Collection, filtration and classification of ZnO powder

Chemical reaction: 2Zn + O₂ → 2ZnO
