Wide range of applications of heavy calcium carbonate: from filler to environmental protection industry-3
Application of Heavy Calcium Carbonate in Coal-fired Power Generation Industry
An important application of heavy calcium carbonate powder in the coal-fired power generation industry is flue gas desulfurization. In the process of coal-fired power generation, heavy calcium carbonate reacts with sulfur dioxide produced by coal combustion to form calcium sulfite, which is then oxidized into gypsum (calcium sulfate) after contact with air. This process can effectively reduce sulfur dioxide emissions, with an emission reduction effect of up to 90%. The generated desulfurized gypsum can also be sold as a by-product for use in cement plants or gypsum board plants. The amount of desulfurized powder used is related to the sulfur content in the coal. Generally, a 300,000-kilowatt coal-fired power plant requires about 40,000 tons of desulfurized powder per year.
Application of Heavy Calcium Carbonate in the Rubber Industry
Heavy calcium carbonate is one of the most widely used fillers in the rubber industry. A large amount of heavy calcium carbonate is filled into rubber, which can not only increase the volume of rubber products, but also effectively replace expensive natural rubber, thereby greatly reducing production costs. After heavy calcium is used in rubber, it can improve the tear strength and wear resistance of the product and show excellent physical properties.
