At present, there are more than 140 iron oxide enterprises in China, but there are only a dozen companies with an annual output of more than 10,000 tons; the production scale of about 60 companies is only about 3,000 tons, and most of them use traditional workshop-style production. There are some problems with quality, production equipment, etc. In the next five years, the domestic iron oxide industry will reduce the number of enterprises and expand the scale of enterprises through market competition, mergers and acquisitions, etc., so that the total production of the top five companies will reach more than 75% of the national total output, and strive to have several sales. Enterprises with revenues exceeding 300 million yuan or more enter the international market and participate in international competition.
It is reported that in 2004 China's total production of iron oxide was 540,000 tons, which has become the world’s largest producer of iron oxide. Among them, more than 50% of the output is used for export, but the export products are dominated by middle and low grades. The varieties are monotonous and the grades are not high, which is incompatible with the status of iron oxide producing countries.
It is understood that with the development of the application field, iron oxide products in the world will develop in a multi-functional direction, extending from the use of coloring, which is currently limited to weathering, durability, and aesthetic decoration, to the identification of soft magnetic computer drives and magnetic inks. Materials, copy magnetic powder, magnetic memory materials, petrochemical catalysts, medical laser detection heads, non-toxic water treatment agents and other new applications.
Experts believe that the development direction of iron oxide in China in the next few years will be: In terms of coatings, iron oxide pigments with low oil absorption and high tinting strength will become hot spots in the market for powder coatings with high solids content and low organic volatiles. , electrophoretic coating and low-pollution curing system coating development requirements; iron oxide for colorants is to be further improved product quality, lower prices, increase market competitiveness; building materials, ceramics need high color strength, corrosion resistance, easy dispersion, High temperature resistant iron oxide products; iron oxide used in magnetic materials is the main direction of the development of magnetic materials in today's world. Iron oxide products are required to have high purity, fine and uniform particles and less impurities.
Iron Oxide Industry in China is More Important but It Is Imperative to Improve Product Quality
According to the latest statistical data, the annual production capacity of iron oxide in China has reached 700,000 tons, and the annual output is 540,000 tons, ranking first in the world. Industry insiders predict that by 2010, the total production capacity will exceed 800,000 tons and sales revenue will reach 3 billion yuan. At present, China's iron oxide industry is "many but not strong." Therefore, reducing the number of enterprises, expanding the scale of unit production, and improving the product quality are urgent tasks.
