There is strong demand for insurance powder in the market
Thread Content
The main application areas for potassium permanganate have seen strong demand in recent years, with rapid growth. In particular, the demand for insurance powder in the textile and dyeing industries is rising steadily, with an increase of 10–15% each year. With the development of high-quality newsprint production in the domestic market and the improvement in the quality of kaolin, this potential market for insurance powder has gradually come to prominence, with its market potential expanding rapidly as well. The global annual consumption of insurance powder is 500,000 tons. Last year, China exported 120,000 tons of it, making it the largest exporter of this substance in the world. Its main export destinations include South Korea, Indonesia, **, India, Japan, Vietnam, Nigeria, Russia, Brazil, Canada, the United States, Australia, and other countries and regions. As the production technologies of Chinese companies specializing in insurance powder continue to improve, their competitiveness on the international stage will increase, enabling them to gain more market share. The domestic consumption is approximately 250,000 to 300,000 tons per year, with the majority of it concentrated in the Jiangsu, Zhejiang, and Shanghai regions.
The quality of safety powder produced by the zinc powder method is relatively good; however, it is not yet available in China
There are mainly three processes for the production of ammonium persulfate: the first is the zinc powder method； The second is the sodium formate method ； Third is the sodium amalgam method. The main production processes for insurance powder used in the world today are the first two. “The \"zinc powder method\" is an old manufacturing process; in the 1970s and 1980s, there were over a dozen such facilities in China. Currently, only two companies remain in the country: \"Wuxi Dongtai\" (with a production capacity of 0.8 tons per year) and \"Taiwan Guotai\" (with a capacity of 2 tons per year). This process is mature and reliable, yielding high-quality products with a yield of 75%, but it is costly and causes significant pollution. Internationally, companies such as Germany’s BASF achieve a yield of 84%.
At our Dongtai Company, due to the efforts to manage the Taihu Lake basin, the use of zinc powder-based safety powder has been discontinued for several years now. Therefore, there is none available in the country at present; Dongtai has now moved to Zhenjiang, and a new wastewater treatment process has been developed, with plans to restart operations this year.
The production technology of sodium formate-based safety powder has made great progress in recent years. The product quality is also becoming increasingly similar to that of the zinc powder method. The content has reached the level of the zinc powder process. The crystallization is slightly poor. The zinc powder method features large crystals and good stability. Little dust.
What is the yield of the formic acid sodium method under what conditions? ? Also, is the amount of wastewater high? What pollutants are mainly present? What is ethylene oxide used for? I think it’s needed, but it didn’t participate in the reaction
What are the market prospects? Is insurance powder a **restricted industry?

The \"sodium formate method\" is a new process that was developed successfully by Mitsubishi Gas Company in Japan in 1969; it makes efficient use of resources, has low costs, and **reduces environmental pollution. Our country is also actively exploring the new \"sodium formate method\" process. In 1980, Sichuan Dye Factory successfully built and carried out pilot production of China’s first production facility using the sodium formate method, with an annual production capacity of 5,000 tons; the yield was only 40%, representing first-generation technology. In 1988, the second large-scale sodium formate-based prussiate production line in China was built in Zhuzhou, Hunan, with an annual production capacity of 15,000 tons; the yield was 60%, and it represented second-generation technology. In 1993, Zhongcheng Chemical Co., Ltd. built a sodium formate-based prussiate of iron production facility with an annual production capacity of 75,000 tons, becoming the world’s largest producer of prussiate of iron. The yield achieved was 80%, and this represented third-generation technology; its technical level far surpassed that of Mitsubishi Gas Company in Japan. In 2009, Hubei Yihua built a sodium formate-based safety powder production facility with an annual production capacity of 100,000 tons; this facility utilizes fourth-generation technology, and its technical level is at the international advanced stage.
The market for insurance powder is actually quite small; currently, two large companies hold a high share of the market, making it very difficult for other companies to enter this sector. At the moment, we also only want to target the high-end market for zinc powder production.
What is the current supply and demand situation for prussic acid? Is it really true that 50% of the production capacity is achieved under the leadership of the Insurance Powder Association?
