Resource advantage is unique
The main raw material for the production of barium chloride is barium resources. The natural resources of barium are mainly barite ore and poisonous heavy stone. The proven reserves of barite ore in the world are 2.2 billion tons, and China's reserves account for 46%. China has 23 provinces and autonomous regions, of which Guizhou is the most, followed by Guangxi, Hunan, Hubei, Shaanxi, Fujian, Tibet, Gansu, Shandong, Henan and other provinces, all have a certain reserve. The poisonous heavy stone mine belongs to rare mineral species. At present, only the United Kingdom and China have been found in the whole world. It was discovered in the 1960s in Settleston, England, but it is not large in scale and has been exhausted. In the 1980s, China had discovered 40 million tons of poisonous heavy stone ore in Dabashan and South Qinling, and carbonate-type antimony ore reserves of 25 million tons were mainly distributed in Houyu, Gaonan, Xinyi and Zuojun. The ore bed is stable and is layered. The ore body is 400 to 1,900 meters long and the thickness of the ore bed is 1.5 meters. Judging from the mining conditions in recent years, the content of barium carbonate extracted from toxic heavy stones is 77%. This provides a reliable guarantee for the development of cesium chloride production in China.
The production level needs to be improved
At present, the utilization rate of barite or toxic heavy gravel in the production of cesium chloride is only about 65%, while the utilization rate in foreign countries is more than 82%. However, after many years of hard work and hard work by researchers, recently our country has made gratifying achievements in the production of barium chloride. The utilization rate of barite or toxic heavy rock has been continuously improved, and in particular, great progress has been made in the treatment of “three wastesâ€. According to the concept of sustainable development of recycling economy, production enterprises use synthetically. In order to control exhaust gas pollution, the use of caustic soda to spray and absorb hydrogen sulfide gas in the tower to produce sodium hydrosulfide has achieved success. In particular, the closed-circuit recycling of waste water is realized, and a certain amount of cement is added to the waste slag to make hollow bricks for building materials, so that the waste residues generated by the company are all converted into product sales, turning waste into treasure, turning damage into profits, and increasing economic benefits.
In recent years, with the increasing demand for barium chloride in the market, users have put forward higher requirements on product quality, especially the requirements for the two indicators including sulfide and iron in products. How to reduce the content of sulfur and iron in barium chloride and improve product quality has become a research subject for scientific research workers and manufacturing enterprises. According to different uses, cesium chloride can be divided into general industrial grade, electronic industrial grade, high purity grade, ultra high purity grade, nano grade and so on. China's industrial guanidine chloride national standard GB/T1617-2002 is only classified into two types of standards for general industrial use and electronic industry. For high purity grade, ultra high purity grade and nano grade, there is no national standard for reference. Although some companies are currently researching and producing high-purity strontium chloride, it is difficult to ensure the consistency and stability of product quality.
Most of the high-grade products on the market are controlled by Japanese, German, and U.S. manufacturers. Domestic demand still depends on imports, and prices are high. Relevant experts pointed out that the development of the cesium chloride industry depends on the support of scientific and technological forces. The most promising varieties of cesium chloride in the coming years are high-purity cesium chloride and nano-sized cesium chloride. Efforts to develop in the direction of refinement and achieve industrial upgrading should be the main thrust of the development of the cesium chloride industry in China.
Industrial upgrading urgently needs to be accelerated
The general idea of ​​the future development of the cesium chloride industry in China should be to establish a security system that is safe, efficient, clean, and sustainable, further extend the industrial chain, achieve a high level of industry concentration, and give full play to its competitive advantages in scale.
First, we need to increase industrial concentration and speed up to scale. The cesium chloride production enterprises should form scale advantages as soon as possible, and adopt the methods of combining strengths and alliances and mergers and acquisitions in accordance with the characteristics of resource and market distribution and the degree of industrial correlation, and establish integration of production and sales across regions, across ownership, cross-industry, and even multinational operations. Large or large group companies to optimize resource allocation, increase industrial concentration, and enhance competitiveness in the international market.
Second, we must increase technological content and promote industrial upgrading. The production of barium chloride must actively strengthen new technologies, new processes, new methods, and new types of equipment to improve product quality. Saving energy and reducing consumption, reforming and innovating process technology, updating equipment, and paying attention to the introduction and absorption of new and high technologies, striving to improve the level of equipment, and making our cesium chloride products move towards mechanization, continuity, automation, functionalization, specialization, and modernization. The direction of development.
Third, we must improve the precision of development and innovation. To develop in the direction of refinement. Expand the application range of cesium chloride and expand the application field. At present, there is still a certain gap between China's product quality and its international counterparts. Therefore, it is necessary to strengthen the joint research and development of various enterprises and form a sharing of scientific and technological achievements. Accelerate the upgrading of cesium chloride products, increase technological content, improve product quality, grade and added value to better meet current and potential needs of users.
Fourth, we must raise awareness of corporate social responsibility, strengthen ecological construction and environmental protection, and implement clean production. It is necessary to vigorously develop and promote the clean production technology of cesium chloride, strengthen ecological construction and environmental protection, and make technological changes in the direction of closed loop systems. From the linear model of "resource-product-waste" to the "recycling of resource-product-waste-recycling resource" model, sustainable economic and social development can be achieved with as little resource consumption and environmental costs as possible.
Strontium Chloride: Upgrading to Main Direction
In recent years, the cesium chloride industry in China has developed rapidly. According to statistics, more than 20 enterprises in 11 provinces and regions in China are engaged in the production of barium chloride, with an annual production capacity of 470,000 tons. China has become a big producer and consumer of barium chloride in the world, and exports to all parts of the world. Products enjoy a high reputation in the international market. According to China's customs import and export data show that in 2005 China's cesium chloride exports 320,000 tons, earning 11.62 million US dollars.
