What are the main application fields of Sodium Bifluoride Technical
Industrial sodium hydrogen fluoride (Sodium Bifluoride Technical) has a wide range of uses and is commonly found in many fields.
In the metallurgical industry, this is the key flux. The ancients said: "If you want to do something good, you must first use your tools." In metallurgy, it is necessary to reduce the melting point of ore and improve the efficiency of metal extraction. Industrial sodium hydrogen fluoride can just help this, making the furnace charge easier to melt. For example, in the smelting of aluminum metal, aluminum oxide can be converted into molten aluminum more smoothly, improving smelting efficiency.
In the field of chemical production, its use is also many. As a raw material for the preparation of other fluorides, just like masonry is used in high-rise buildings, many fluoride synthesis is based on this. Many fluorine-containing fine chemicals are converted from it. In addition, in some special chemical reactions, industrial sodium hydrogen fluoride can act as a catalyst to accelerate the reaction process, shorten the production cycle, and save costs.
In the glass industry, it is also indispensable. It can adjust the chemical composition of glass and improve the properties of glass. For example, when manufacturing optical glass, it can change the optical properties such as refractive index and dispersion of the glass, making the glass suitable for different optical instruments to meet the needs of ancient people for viewing celestial phenomena and making mirrors. In modern times, it is widely used in the manufacture of camera lenses, telescope lenses, etc.
In the electroplating industry, industrial sodium hydrogen fluoride can be used as an additive for electroplating solutions. It can improve the quality of the coating, make the surface of the plating smoother and more uniform, and enhance the bonding force between the coating and the substrate, so that the object can still maintain a good appearance and protective performance over time, just like putting a strong armor on the object.
What are the Quality Standards for Sodium Bifluoride Technical
The quantity of fluoric acid (Sodium Bifluoride Technical) has been determined in ancient times. The first and foremost is the degree of composition. The high-quality workmanship of fluoric acid, the content of its main component, fluoric acid, is high, and there must be no excessive mixing. This is the foundation for ensuring its effective efficacy in industrial applications.
Secondly, external factors are also important considerations. Usually in the shape of uniform, or powder, or whole grains, the color is also in line with normal conditions, and there should be no color or taste, no or hint of quality or quality defects.
Furthermore, due to its physical rationality, such as particle size distribution, certain requirements need to be met. Too coarse or too thick grains may affect their use in different industrial processes. For example, in some combinations that require homogeneous mixing, the inconsistent particle size distribution may cause uneven mixing, which will affect the best quality of the product.
Qualitative properties are particularly important. Fluoric acid is difficult to decompose or cause adverse reactions in the surrounding environment under normal storage conditions. In this way, it can maintain its original products in the process.
In addition, the limit of harmful substances should not be ignored. The content of harmful substances such as heavy metals must be controlled at a certain level to avoid adverse effects on the environment, people and downstream products in the process. In addition, the amount of fluoric acid in the work is the whole of the mutual production and cooperation of various factors. Only when all elements meet the requirements can qualified products be used for general work.
What are the precautions for industrial sodium bifluoride (Sodium Bifluoride Technical) during storage and transportation?
Sodium Bifluoride Technical (Sodium Bifluoride Technical) is not suitable for storage, and general matters need to be paid attention to.
The first important environment for its storage is the environment. It is suitable to use a good place for dryness and communication, and to create a fire and a source. This is due to the fact that fluoric acid is exposed to moisture or damage, and it is easy to be biochemically damaged, prone to modification, or dangerous. And it needs to be stored in equal parts of oxidation and acid, and must not be mixed, so as to prevent mutual opposition and formation. In the process, there is also a suitable way to contain and remove leaks, so as to prevent leakage.
It is necessary to use packaging materials that can withstand turbulence and effectively block external factors, so that the fluoric acid in the process is not damaged or leaked. It is also necessary to clean up the dryness and dryness, and do not leave behind objects that can be reversed. It is necessary to have knowledge and knowledge of the dangerous characteristics of fluoric acid and the emergency disposal method. On the way, pay attention to the weather at all times, and take preventive measures in case of unfavorable items such as rain and tide. And on the way, it is necessary to avoid sensitive areas such as densely populated areas and water sources to reduce the cost. If there is a leak on the way, it is necessary not to panic, that is, to quickly isolate the leakage and pollution, restrict the entry and exit of people, and take measures according to the amount of leakage and the degree of harm.
Is Sodium Bifluoride Technical Compatible with Other Chemicals?
Industrial sodium hydrogen fluoride (Sodium Bifluoride Technical) does have compatibility problems with other chemicals. Industrial sodium hydrogen fluoride is active, corrosive and reactive, and may react violently when exposed to different chemicals.
In case of strong acid, industrial sodium hydrogen fluoride will release hydrogen fluoride gas, which is highly toxic and corrosive. In poorly ventilated areas, it can cause serious health hazards and safety accidents. And if it encounters with certain metal salts, or undergoes a metathesis reaction, generating new compounds, or changing the properties and stability of the system.
When talking about its relationship with alkaline substances, acid-base neutralization reactions often occur instantaneously, or cause heat release, system temperature rise, if not properly controlled, or cause danger.
And fluorine ions in industrial sodium hydrogen fluoride have strong coordination ability, and can form complexes with a variety of metal ions. If there are metal ions that can be coordinated in the system, or change the shape and reactivity of metal ions.
Therefore, when using industrial sodium hydrogen fluoride, it is necessary to know in detail its interaction with other chemicals, strictly evaluate the compatibility before operation, follow safety procedures, and take protective measures to avoid dangerous reactions and accidents, and ensure personnel safety and production stability.
What is the production process of industrial sodium bifluoride (Sodium Bifluoride Technical)?
The production process of fluoric acid (Sodium Bifluoride Technical) is not directly described in ancient books, but it can be deduced from today's chemical principles and technologies.
First of all, it is necessary to clarify its raw materials, such as fluoric acid, often used as fluoric acid (HF), carbonate ($Na_2CO_3 $) or oxidation ($NaOH $) raw materials. Fluoric acid is a humic acid, and its source is mostly from stone ($CaF_2 $) and sulfuric acid ($H_2SO_4 $). This inverse formula is $CaF_2 + H_2SO_4 () \ stackrel {\ Delta }{=\!=\!=} CaSO_4 + 2HF\ uparrow $.
When fluoric acid is obtained, it will enter the reverse step. If the reaction of fluoric acid and carbonate is reversed, according to the principle of chemistry, the reaction is as follows: $2HF + Na_2CO_3 {=\!=\!=} 2NaF + H_2O + CO_2\ uparrow $, then this step is to obtain fluoride ($NaF $), and it is still necessary to take one step. The reaction of fluoric acid, $NaF + HF {=\!=\!=} NaHF_2 $, to obtain fluoric acid.
If the oxidation of fluoric acid is reversed with fluoric acid, it can be directly obtained. The inverse formula is $2HF + NaOH {=\!=\!=} NaHF_2 + H_2O $. This reaction needs to control the ratio of raw materials. Due to the amount of fluoric acid or insufficient, it will affect the efficiency of the material.
If the reaction is reversed, it is involved in the separation and extraction. Because the mixture obtained by the reaction or contains raw materials, side substances, etc. that are not reversed. Usually, the first reaction is to remove insoluble substances, such as the reaction or the generated sulfuric acid. And the method of steaming, so that the solubility of the solution is increased, the solution is high, and then cold crystals, and the fluoric acid is precipitated in the form of crystals. The most important means is to obtain fluoric acid, to dissolve and wash, to remove the surface adhesion, and to dry, that is, to obtain the finished product of fluoric acid.
The whole production process, the control of raw materials, the control of reverse parts, and the separation and extraction of raw materials, all need to be completed. With a little difference, high-quality fluoric acid can be obtained.
