According to a report from China Chemical Industry News, Xi'an University of Science and Technology and Zhejiang Wansheng New Material Company have developed a new type of carbon black. It is reported that this new type of carbon black material has reached a nanometer level in structure, and the conversion rate can reach 99% during the application process, and it is basically no loss. It is a new type of carbon black with capacity expansion and reinforcement, and it has improved rubber. Product performance, improve the processing environment, reduce production costs and other advantages.
Carbon black is a fine powder produced by incomplete combustion of a carbonaceous raw material (mainly petroleum). The appearance is pure black fine or powdery material. The depth of the color, the fineness of the particles, and the specific gravity are all different depending on the raw materials used and the method of manufacture.
Carbon black is an indispensable chemical raw material in the industry. Its dyeing and reinforcing properties are the majority of additives for plastics and rubber products, among which tires account for 70% of the total. In order to ensure the supply of strategic materials, forcing carbon black manufacturers to expand their production to a large extent, with an annual output of 1.6 million metric tons. The Asian region has recently been driven by the strong economic growth of factories in the Chinese mainland. Japan and mainland China rank second or third place, with an annual output of approximately 700,000 metric tons.
At present, more than 90% of the carbon black in China is produced by the oil furnace process. The dust pollution of this process has become a worldwide problem. Since 1998, Wansheng has established a strategic cooperative relationship with Xi’an University of Science and Technology, and has used its own research and development “ultrafine grinding - particle shaping - mechanical force chemical modification†integrated production process to make the entire product clean and environmentally friendly in the production process. To achieve "three wastes" zero emissions.
It is understood that this carbon black is a new type of low-density soft semi-reinforcing carbon black, and its performance is similar to that of soft semi-reinforcing carbon black. At present, the company has a production capacity of 80,000 tons/year, and the price is only that of conventional carbon black products. Half of it.
