Zinc oxide is an important branch of inorganic chemical zinc salt series. Zinc oxide as basic chemical raw materials and has a broad application field. With the development of science and technology, make many characteristics of zinc oxide by people to meet. Zinc oxide has the characteristics of the function be used for new science and new business development, become indispensable in the construction of the national economy important basic chemical raw materials and new materials. Such as nano zinc oxide was hailed as the 21st century new materials. Zinc oxide is mainly divided into the indirect method zinc oxide, direct method zinc oxide and zinc oxide by wet method.
Is mainly used in electronics, medicine, rubber paint and other industries, especially rubber electronic industry such as high-grade products most used as 99.7% purity of indirect zinc oxide; Mid-range products using the purity of more than 95% of the direct method zinc oxide; Oily coating is most direct method zinc oxide with lead. Zinc oxide industry is developing rapidly in recent 10 years. Ten years ago, zinc oxide production enterprises in the country is not much, no more than 20 enterprises with annual capacity of 3000 t. With the high development of the national economy, zinc oxide in increasing domestic demand, promote the development of the zinc oxide production enterprises, expanding production capacity. Incomplete statistics from the last five years, the production capacity of the indirect method zinc oxide from more than 10 T, has risen to more than 30 T; Less than 3000 T, wet activated zinc oxide has risen to 30000 T. National scale of zinc oxide direct method zinc oxide, indirect method zinc oxide and wet zinc oxide can output has reached more than 1 million T/A (those in the production of low grade zinc oxide are not counted). Has a wide distribution at the same time, it is also a, the number is more, the raw material is miscellaneous, management technology and extensive industry. But in terms of zinc resources recycling, has a larger space.
