China's zinc oxide industry status Zinc oxide is an important branch of the inorganic chemical zinc salt series. Zinc oxide has a common use as a basic chemical raw material. With the development of superstitious technology, many characteristics of zinc oxide have been reconsidered. The characteristic functions of zinc oxide have been developed for use in new superstitions and new industries, and have become an essential basic chemical raw material and new data in the establishment of the national economy. Such as nano-zinc oxide is known as the new information of the 21st century.
Zinc oxide is mainly divided into direct zinc oxide, indirect zinc oxide and wet zinc oxide. Secondary used in rubber electronics, pharmaceutical coatings and other industries, especially in the electronics industry, such as high-end products, a small number of direct use of purity of 99.7% of the direct method of zinc oxide; mid-range products use more than 95% purity of the indirect method of zinc oxide; oil paint a few applications indirect Method lead zinc oxide.
The zinc oxide industry is a fast-growing industry in the past 10 years. 10 years ago, there were not many companies that consumed zinc oxide in the country, and there were no more than 20 companies that produced 3,000 tons per year. With the rapid development of the national economy, the demand for zinc oxide has increased from time to time, and the development of zinc oxide consumer companies has been promoted. The production capacity has expanded from time to time. From the incomplete data statistics in the last five years, the production capacity of direct zinc oxide has risen from more than 100,000 tons to more than 300,000 tons; wet activated zinc oxide has been deficient to 3,000 tons, and it has risen to 30,000 tons; Zinc oxide, indirect zinc oxide, has a total production capacity of over 1 million t/a for both direct and wet zinc oxide (those that consume low-grade zinc oxide are not counted). At the same time, it is also an industry that spreads widely, has a large number of raw materials, and has intensive management techniques. However, there is much room for the recycling of zinc resources.
In recent five years, the production capacity of zinc oxide has been growing faster, especially for direct zinc oxide. This is mainly due to the high-speed development of China's auto industry and highways, power grids, home appliances and digital communications industries. For radial tires such as radial tires, direct radial zinc oxide is used. In the past three years, the radial tires are carried out at a rate of 25% to 30% each year. In 2005, it exceeded 50% of the total tire volume, making direct-process zinc oxide progress at a rapid pace. At the same time, international and international magnetic data are rapidly developing, especially the consumption of soft magnetic data is already the world's first production capacity, and China has become the world's manufacturing center for ferrite magnets. In zinc-manganese ferrite, zinc oxide is the main raw material. In the manufacture of medium and high-grade soft magnetic materials, varistor grade high-grade zinc oxide must be consumed directly. The development of magnetic data has also advanced the technological upgrading of high-quality zinc oxide consumption. The special function of nano-zinc oxide has once again triggered the research and development of nano-zinc oxide throughout the country, and there are only a few companies that can really consume nano-zinc oxide products. The study of functional zinc oxide and nano-zinc oxide has, after all, promoted the development of zinc oxide industry and improved technology. Under the condition that the price of zinc ingots is falling from time to time, the prospect of active zinc oxide is better than the purpose of how to use resources, waste resources, and reduce costs. In recent years, wet zinc oxide has lost a lot of development, and it is believed that this development trend will lose its long-term continuation.
