Sodium chlorate is an important inorganic chemical product with a wide range of applications and markets worldwide. In the world, 92% of sodium chlorate is used as raw material for pulp treatment and drinking water treatment: 98% of sodium chlorate in North America is used in pulp and paper industry, and the remaining 2% is used in the preparation of chlorate, mining, etc. 84% of sodium chlorate in Europe is used in the paper industry, 7.8% is used in the manufacture of other chlorates and chlorites, 4.2% is used in the manufacture of herbicides, and the remaining 4% is used in uranium ore and others. 73% of sodium chlorate in Japan is used in the paper industry, 6% is used in the preparation of oxidants and other chlorates, 5% is used in herbicides, and 16% is used in textiles and other industries. At present, the production and sales volume of sodium chlorate in the world is about 3 million tons, and the manufacturers are mainly concentrated in North America (Canada, the United States) and Northern Europe (Scotland, Sweden). Among them, the output in North America is about 1.7 million tons/year, the output in Northern Europe is about 720,000 tons/year, and the output in Japan is about 80,000 tons/year. The production capacity of Canada and the United States exceeds 1.9 million tons/year, and the output of sodium chlorate in Sweden and France is also more than 200,000 tons/year, while that in my country is less than 200,000 tons (including the sodium chlorate consumed for the production of potassium chlorate) .
The United States is a big consumer of sodium chlorate. Although the continuous expansion of new devices still needs to be imported from Canada, Sweden and other countries to meet the needs of pulp bleaching and drinking water treatment. In Finland, Sweden, France and other countries in Europe, pulp and paper products manufacturers use chlorine dioxide as a bleaching agent to develop rapidly. In Japan, its demand is also rising year after year, and it is a long-term importer of sodium chlorate.
The main reasons why foreign pulp mills use chlorine dioxide bleaching: First, the needs of environmental protection work,
The traditional method of bleaching pulp with chlorine will produce strong carcinogens, and it is also easy to form chlorine with humus in water.
