They are asking about the price of high-purity sulfur hexafluoride. Today, the manufacturer of Philier special gas will analyze the price with you.
The price of high-purity sulfur hexafluoride depends on the production mode, which determines the cost of sulfur hexafluoride gas and its preparation process. At present, the methods of producing gas mainly include electrolysis method and direct method. The direct method can be divided into three ways: fluorine gas and solid sulfur, molten sulfur and sulfur vapor. However, the direct reaction of fluorine gas and solid sulfur will have a very intense exothermic reaction, which will produce many unnecessary by-products and increase the cost of subsequent treatment. When fluorine reacts with sulfur vapor, the temperature is not easy to control, and special reaction vessels must be used. The production cost directly affects the price of sulfur hexafluoride.
The temperature during the reaction of fluorine gas and molten sulfur is well controlled. As long as the fluorine gas and molten sulfur level are introduced in a parallel direction, a high reaction yield can be maintained. This method is widely used by domestic and foreign high purity sulfur hexafluoride manufacturers. This production method can be used on a large scale, and indirectly reduces the price of sulfur hexafluoride.
The electrolysis principle is to prepare high-purity sulfur hexafluoride gas by using electrolytic corrosion to react with sulfur at high temperature. The advantage of electrolysis method is that the fluorine gas produced by electrolysis can react with sulfur immediately to avoid explosion caused by the reaction between fluorine gas and hydrogen gas, which saves reaction equipment and improves safety. Industrial production is convenient. When considering the cost of sulfur hexafluoride, the convenience of the process is also one of the decisive factors.
In addition, market demand also determines the price of sulfur hexafluoride at Liming. In the late 1970s, the global consumption of SF6 was 3500 tons. Since 2004, the sharp increase of domestic high-voltage electrical equipment exports has directly driven the sulfur hexafluoride market. At the same time, the international market for high-purity sulfur hexafluoride gas is booming and the price is soaring, which further leads to a sharp increase in domestic SF6 exports. It goes without saying that the price will naturally rise.
