[China Aluminum Network] Recently, the self-developed Fluorosilicic acid (sodium) dry process aluminum fluoride technology developed by Huangfu Chemical Technology Co., Ltd. and Huang? M Fluorine Chemical Technology Institute has been successful in the pilot test. This technology solves the problem of fluorosilicon. There are two problems in the development and utilization of acid (sodium). First, the use of large amounts is how to consume a large amount of fluorosilicic acid and sodium fluorosilicate, and the second is greater efficiency, that is, how to obtain a higher economic value of the product. . This technology has found new vitality for both fluorosilicic acid (sodium) and aluminum fluoride products.
Aluminum fluoride is a product of a large amount of production and demand in all fluorine chemical end products. At present, traditional hydrogen fluoride-dry aluminum fluoride is produced by gas-solid fluidization of hydrogen fluoride gas and aluminum hydroxide to obtain dry fluorination. Aluminum products. Due to the fact that its products are of better quality (larger than specific gravity, lower moisture content) and better use effect, they will be launched in large areas from 2005 to 2010, and their profits will reach about 20% from 2005 to 2008. Since 2008, due to financial With the crisis and overcapacity, the operating rate of the equipment is less than 50%, and its profit rate has dropped below 5%. Hydrogen fluoride - Dry aluminum fluoride has a problem of excess production capacity and serious homogenization of product technology. Dry aluminum fluoride companies are struggling.
In the face of the current plight of aluminum fluoride, it is difficult to seek breakthroughs in the quality and cost of existing process technologies, and only new production processes and resources can be developed.
Fluorite is an important source of fluorine, but it is not a source. It is known that the world reserves of apatite are about 60 billion tons, and China's reserves are more than 15 billion tons, of which the average fluorine content is about 2-4%. Obviously, the associated fluorine resources in phosphate rock are far larger than those in fluorite, and will be one of the important resources for global fluoride production in the future. Phosphorus and hydrogen fluoride by-produced fluorosilicic acid are a kind of cheap fluorine resources, due to the low degree of development of fluorosilicic acid deep processing technology, at present, the main product is still sodium fluorosilicate, the product has low added value, along with the production of phosphate fertilizer and hydrogen fluoride With the rapid increase, the production of fluorosilicic acid (sodium) has also increased rapidly. The lag in application development has caused a large amount of backlog prices to decline, which has restricted the development of related industries, caused greater environmental risks, and caused a great waste of fluorine resources.
Fluorosilicic acid (sodium) production of dry aluminum fluoride technology, is a senior expert in the fluorine industry industry, Mr. Wong Yen-li, after years of painstaking research and practice, after the original theoretical proof, experimental research and pilot production, and finally succeeded. This technology uses fluorosilicic acid (sodium) to produce dry aluminum fluoride products. The product quality is excellent. The production cost is reduced by 30 to 50% compared to the hydrogen fluoride method. The economic and environmental benefits are significant. It is the solution to the breakthrough and breakthrough of fluorosilicic acid (sodium). The better method for aluminum fluoride dilemma.
The technology uses fluorosilicic acid or sodium fluorosilicate as the raw material after desiliconization to obtain decomposable fluoride, and then reacts with aluminum hydroxide to obtain dry aluminum fluoride. The quality of dry aluminum fluoride products is excellent, and all the indicators have reached the national standards. In particular, the key moisture and bulk density have reached the standard of traditional dry aluminum fluoride. In this technology, the dry aluminum fluoride reaction uses a new type of equipment that can replace the traditional dry aluminum fluoride more critical fluidized bed reactor.
The major feature of this technology is that it does not undergo hydrogen fluoride production, does not use sulfuric acid, is simple in technology, has a small investment, and has a low cost. It is superior to the current technology with complicated processes, high investment, and high cost to produce hydrogen fluoride by fluorosilicic acid; and fluorosilicic acid Both fluorosilicic acid sodium and sodium fluorosilicate can be used, which breaks the regional restrictions and is superior to the current technology for the production of hydrogen fluoride from fluorosilicic acid that can only be built near phosphate fertilizer companies.
