What are the Main Applications of Sodium Bifluoride Technology

Sodium (Sodium) and sodium hydrogen fluoride (Bifluoride Technical) have different uses.

Sodium is widely used. In the field of metallurgy, it is often used as a reducing agent to extract rare metals such as titanium, zirconium, and hafnium. Because sodium has strong reducing properties, it can reduce and precipitate other metals from its compounds. In chemical production, sodium is an important raw material for the production of various sodium compounds, such as sodium peroxide and sodium hydride. Sodium peroxide can be used as a breathing mask and an oxygen supply agent because it can react with carbon dioxide to release oxygen. In nuclear reactors, sodium is used as a coolant because of its good thermal conductivity, which can effectively export the heat generated by the reactor and ensure the stable operation of the reactor.

Sodium hydrogen fluoride, in the chemical industry, is a key intermediate for the manufacture of other fluorides. In the aluminum electrolysis industry, it can be used as a flux to reduce the melting point of alumina, reduce the energy consumption of the electrolysis process, and improve the production efficiency of aluminum. In the field of metal surface treatment, sodium hydrogen fluoride can be used for metal etching and cleaning. It can react with metal surface oxides to remove impurities, make the metal surface cleaner, and enhance the adhesion of subsequent coatings or coatings. It is also used in wood corrosion protection, which can inhibit the growth of microorganisms in wood and prolong the service life of wood.

What Are Sodium Bifluoride Technical Quality Standards?

Sodium and sodium difluoride (Sodium + Bifluoride Technical), its Quality Standards are related to industrial matters and are of paramount importance.

Sodium has a soft texture, active chemical properties, and is easily oxidized in the air. Its Quality Standard is the first purity, high purity sodium, and impurities must be minimal. Many impurities affect the accuracy of its chemical reaction. In the chemical industry, metallurgy and other industries, or cause products to be impure and of low quality. Usually, when the purity of industrial sodium reaches more than 99%, the impurities such as calcium, magnesium, and iron must be limited in strict proportions to ensure its stable performance in various reactions.

Sodium difluoride, toxic, is an inorganic compound. Its Quality Standard, one is purity, high purity products, can be used in aluminum electrolysis, ceramics and other industries. Second, particle size is also the key. Appropriate particle size is conducive to its uniform dispersion in the reaction system and accelerate the reaction process. Third, the moisture content must also be strictly controlled. Excessive moisture or hydrolysis of sodium difluoride will affect its chemical activity and use efficiency.

In industrial applications, the purchase of these two must be verified according to clear Quality Standards. If the purity of sodium is tested, chemical analysis can be used; the particle size of sodium difluoride can be measured by sieving, laser particle size analysis, etc.; if the moisture is detected, the Karl Fischer method can be used. According to this strict standard and testing method, we can ensure smooth industrial production and high product quality.

Sodium Bifluoride Technical Storage and Transportation

Sodium (Sodium) and sodium hydrogen fluoride (Bifluoride Technical) need to pay attention to many things when storing and transporting.

One is related to storage. These two should be stored in a cool, dry and well-ventilated place. Because of its active nature, if it is damp or in a high temperature environment, it is easy to cause chemical reactions. Sodium hydrogen fluoride is corrosive. Once it comes into contact with water vapor, it may produce corrosive gases, so it is necessary to ensure that the storage environment is dry. And it needs to be stored separately from flammable, flammable and acids to avoid danger caused by mixed storage. Sodium will react violently in contact with water, generate hydrogen and emit heat, which may cause combustion or even explosion. Therefore, it should be stored away from water sources and humid places.

Second, about transportation. During transportation, the packaging must be tight to prevent leakage. For sodium, it is usually transported by immersing in an inert medium such as kerosene or liquid paraffin to isolate air and moisture. Because of the corrosive nature of sodium hydrogen fluoride, the transportation container must have good corrosion resistance, and corresponding warning signs, such as corrosion product labels, should be posted. Transportation vehicles should also be equipped with emergency treatment equipment, such as fire extinguishers, adsorption materials, etc., to prepare for emergencies. Transportation personnel must be professionally trained, familiar with the characteristics of the transported items and emergency disposal methods, and regularly check whether the packaging is in good condition during transportation to ensure safe transportation.

Sodium Bifluoride Technical Production Process

The art of making sodium and sodium difluoride has never been heard of in ancient times, but today's technology also follows the rules of physics and chemistry, and uses exquisite methods.

The art of making sodium is often done by electrolysis of molten sodium chloride. In a special electrolytic cell, graphite is used as the anode and iron is used as the cathode. The cell contains sodium chloride, which is heated to a molten state, and is connected with direct current. At the anode, chloride ions lose electrons and become chlorine gas to escape; at the cathode, sodium ions gain electrons and precipitate sodium metal. This process requires strict control of temperature, current and other conditions to preserve yield and purity.

As for sodium difluoride, the preparation method is often to react hydrofluoric acid with sodium hydroxide or sodium carbonate. First take an appropriate amount of hydrofluoric acid, slowly add sodium hydroxide solution, control the degree of acid-base neutralization, the following reaction occurs: $HF + NaOH\ longrightarrow NaF + H_2O $. Then the obtained sodium fluoride solution is passed into excess hydrofluoric acid, so that sodium fluoride further reacts with hydrofluoric acid to obtain sodium difluoride: $NaF + HF\ longrightarrow NaHF_2 $. After the reaction is completed, the sodium difluoride product can be obtained through evaporation concentration, cooling crystallization, filtration, drying and other processes. When preparing, pay attention to the corrosiveness of hydrofluoric acid, and operate in a well-ventilated and well-protected environment to protect personal safety.

In summary, the production process of sodium and sodium difluoride depends on scientific principles and fine control to produce high-quality products and meet the needs of industry.

What is the Market Price Range of Sodium Bifluoride Technical

The market price range of sodium and sodium hydrogen fluoride (Sodium + Bifluoride Technical) is difficult to cover. The market price of the two often fluctuates due to many factors.

First of all, sodium is an active metal, and the production requires a specific process. If it is obtained from sodium chloride by electrolysis, its cost is related to the price of electricity, equipment loss and manpower. And sodium has a wide range of uses and is needed in chemical synthesis, metallurgy and other fields. In chemical synthesis, it is an important reducing agent; in metallurgy, specific metals can be refined. If the chemical industry is booming and the demand for sodium increases sharply, its price may rise; conversely, if the demand is weak, the price may drop. In the past, due to the expansion of some chemical projects, the demand for sodium was strong, and its price could reach tens of yuan per kilogram; when the market was sluggish, it may drop to several yuan per kilogram.

Besides sodium hydrogen fluoride, its preparation also involves the cost of raw materials and production process. The purity of raw materials and the difficulty of obtaining them all affect the cost. Sodium hydrogen fluoride is mostly used for etching glass and metal surface treatment. In the glass etching industry, if the demand for characteristic glass in the fields of architectural decoration is high, the demand for sodium hydrogen fluoride also increases, and the price may rise. There was a stage where the price per ton could reach thousands of yuan due to the prosperity of the architectural decoration industry; and in the off-season of the industry, the price may fall back to around 1,000 yuan.

In short, the market price of sodium and sodium hydrogen fluoride is influenced by raw material supply, market demand, policies and regulations, and the international situation. It is difficult to determine the exact range, and it needs to be considered in detail according to the specific situation.
