Nano zinc oxide has excellent comprehensive properties and market demand will continue to increase

Nano zinc oxide is a high-end, multi-functional new fine inorganic material with a particle size between 1-100nm. Due to the miniaturization of crystal grains, nano-zinc oxide has excellent fluorescence, piezoelectricity, dispersion, and ability to scatter ultraviolet light. With its excellent properties, nano-zinc oxide can be used to prepare fluorescent materials, photocatalytic materials, stealth materials, and ultraviolet light. Shielding materials, etc. are widely used in ceramics, electronics, medicine, chemical industry, rubber, textile and other fields.

Globally, the Asia-Pacific region has the highest zinc oxide market share, and in the Asia-Pacific region, my country is the largest zinc oxide market. my country’s zinc oxide market is huge, and zinc oxide market demand is showing a steady growth trend. However, due to limitations in preparation technology, my country’s zinc oxide industry structure is currently unbalanced. Micron-grade zinc oxide still occupies a certain market share. As consumption upgrades, nano-zinc oxide replaces The space is vast.

According to the “2022-2026 China Nano Zinc Oxide Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, There are many nano-zinc oxide manufacturers in my country, including Liaoning Lanen Environmental Protection Technology, Fujian Zhongxiang Nano Technology, Lanshi Zhongke, Shanxi Fenghai Nano Technology, Shaanxi Zhongke Nano Materials Co., Ltd., etc., and market competition is intensifying. Nano zinc oxide products are seriously homogenized, and the market is in urgent need of innovative and high-end development.

The preparation process of nano zinc oxide is divided into direct method, indirect method, wet method, acid method, ammonia method, etc. The indirect method uses zinc ingot as raw material, which is converted into zinc vapor at a high temperature of 1000°C in a graphite crucible, and is then blown The incoming air oxidizes to form zinc oxide. The indirect method has a simple process and high product purity. It is the current mainstream preparation process, accounting for about 70%. However, in recent years, with the strict environmental protection supervision and the continuous advancement of energy conservation and emission reduction, relevant companies have begun to accelerate the improvement of nano-zinc oxide preparation processes, and new , high efficiency and environmental protection have become its upgrade trends.

International suppliers of nano zinc oxide include Ever Zinc, U.S. Zinc., Umicore, Rubamin, etc. Compared with international brands, the performance of my country’s nano zinc oxide products is lower. In recent years, in order to speed up the domestic substitution of high-end nano-zinc oxide, Chinese companies have begun to deploy the high-end nano-zinc oxide market. For example, in 2020, Lanen Environmental Protection’s 1,000-ton annual high-activity nano-zinc oxide production line using independently developed production technology was put into production. 30-50nm, the maximum catalytic activity of the product is retained, and the performance is comparable to similar imported products.

Industry analysts said that due to the nano-effect, nano-zinc oxide has a larger specific surface area and higher photocatalytic oxidation activity. Under the upgrade, the demand for nano-zinc oxide in electronics, medicine, ceramics and other fields will be further released. There are many nano-zinc oxide manufacturers in my country, and market competition is intensifying. As the supply-side structural reform deepens, backward nano-zinc oxide production capacity will accelerate its exit from the market, and the proportion of new, efficient, and environmentally friendly high-end nano-zinc oxide will continue to increase.
