Environment-friendly tire industry to silica

With the social awareness of environmental protection and energy saving awareness of the growing low-rolling resistance tires green energy saving and environmental protection needs of gradual increase in global demand for carbon black with an annual 4% to 5% of the rate of growth. China's domestic and, in the tire and footwear industry, led by demand for carbon black with more each year on 8% to 10% of the rapid rate of increase. As a result, silica in the development of our prospects.

That is, nano-silica dioxide can increase the strength of rubber products, such as wear resistance and anti-aging properties, but also to maintain the same color products. In addition of silica tires, and rubber to reduce the lag and the heat, thus reducing the rolling resistance tires, fuel economy, reduce vehicle emissions and increase the number of tires for the renovation, the production of green tire is an ideal material.

In 2004, China's rubber industry, with the black actual demand for 225,000 tons, accounting for the consumption of silica 69%, much higher than the world average of 30% of the proportion of consumption, but most of them still used in the footwear industry, Domestic tire industry the amount of silica is only 25,000 tons, mainly used in steel and tire rubber in the tread; in the semi-steel tire tread compound, in addition to some foreign enterprises in the production of tires, mid-range car tires when the original Use, in general do not have to silica. However, with the tire industry and the increasing demand for green tires, tires in China is expected to use the silica will be an annual 19.3 percent rate of growth in 2005 and 2015 our country silica tire demand will reach 30,000 tons and 72,000 tons.

Although the tradition is expected to rubber shoes and other rubber products, light-colored silica demand growth of only 4%, but due to a larger amount, in 2005 and its 2010 demand will reach 208,000 tons and 253,000 tons.

But the concern is that in 2004 China's silica production capacity has reached 408,000 tons, the output of 346,000 tons, while domestic demand is only 326,000 tons, and exports of 126,000 tons. If it continues to blindly expand production capacity, do not pay attention to improving the quality of the product, is bound to lead to an oversupply. Combined with silica domestic prices would seriously reduce corporate profits.

Take Europe as a result of the use of wet tire traction and rolling resistance of the high, green tire in the European market developed rapidly, but the EU has already provided that the child must be in original new green tire, so Europe is the use of the highest proportion of silica. Therefore, domestic enterprises can develop in the high-dispersed silica and easy dispersion of new products at the same time, and continuously improve product quality and expand exports, especially exports to Europe.
