In the direct method of zinc oxide production, the zinc-containing ore, coal, and lime are arranged in a spherical shape in proportion to be fired, and the zinc oxide in the zinc-containing ore undergoes continuous high-temperature firing at 1300°C to generate oxidation reaction with coke to form zinc vapor.
In the direct method of zinc oxide production, the zinc-containing ore, coal, and lime are arranged in a spherical shape in proportion to be fired, and the zinc oxide in the zinc-containing ore undergoes continuous high-temperature firing at 1300°C to generate oxidation reaction with coke to form zinc vapor. Zinc vapor is then oxidized by oxygen in the air to obtain zinc oxide.In zinc-manganese ferrite cores, zinc oxide is the main raw material.In the manufacturing of medium and high-grade ferromagnetic materials, the indirect method shall be used to produce the high-end zinc oxide varistor grade zinc oxide.The development of permanent magnet materials has in turn driven technological advances in the production of high quality zinc oxide.The special functions of nanotechnology zinc oxide have once again caused the research and development of nanotechnology zinc oxide all over the country, but there are only a few companies that can really produce nanotechnology zinc oxide goods.The scientific research of multifunctional zinc oxide and nanotechnology zinc oxide has finally promoted the development and technological progress of zinc oxide industry.With the overall goal of resource utilization, energy conservation and cost control, the market outlook for activated zinc oxide is more appropriate.In the past few years, wet process zinc oxide has been developed for a long time, and it is believed that this kind of development trend will be sustained for a long time.Zinc oxide is one of the main branches of the inorganic chemical zinc salt series in China.
Zinc oxide has a wide range of applications as a basic chemical raw material.Thanks to the development of technology, many features of zinc oxide are being re-understood by everyone.The characteristics of zinc oxide have been developed and designed to be used in new scientific fields and a new industry, turning it into an important basic chemical raw material and new material indispensable for social and economic construction.For example, nanotechnology zinc oxide is called the new material of the 21st century.e purity of 99.7% of the indirect .Medium product application of Direct zinc oxide with a purity of 95% or more is used for medium products; direct zinc oxide with lead is mostly used for oil-based coatings.The zinc oxide industry is a rapidly developing industry in the past 10 years.Ten years ago, there were very few companies producing zinc oxide across the country, and there were no more than 20 companies with an annual output of 3,000 tons.Along with the socio-economic development, zinc oxide requirements continue to expand in China, driving the development of zinc oxide production companies with expanding production capacity
From the recent 5-year incomplete data analysis, the indirect method of zinc oxide production tons, has long been elevated to 30,000 tons The total production capacity of zinc oxide, direct zinc oxide, indirect zinc oxide and wet zinc oxide, has reached over 1 million tons/yea ron a national scale.(This production of low grade zinc oxide was not analyzed within the statistics) That is a more widespread, more total, more miscellaneous raw materials, management technology rough type of industry.However, there is a lot of room for recycling of zinc network resources.The capacity of zinc oxide tends to increase rapidly in the last 5 years, especially the rapid development of indirect method zinc oxide, usually benefited from the rapid development in China's automotive industry and highway, power grid and its household appliances, digital communication system and other industries .For example, the radial tires use indirect zinc oxide, and the radial tires have been developing at a rate of 25%-30% every year for the past 3 years, and in 2005, the total output of the tires exceeded 50%, which prompted the rapid development of indirect zinc oxide.At the same time the international and domestic permanent magnet materials also developed rapidly, especially the production of ferromagnetic materials has been the world's first production capacity, has become the world manufacturing center of magnetic materials ferrite cores.
