The Useful Of Ammonium Bifluoride
Ammonium bifluoride (NH4HF2) is a chemical compound that has several practical applications. Here are some of its uses:
1. used as glass matting, frosting, etching agent (often used with hydrofluoric acid).
2. Used as chemical reagent, disinfectant and preservative of fermentation industry, solvent of beryllium oxide to metal beryllium, and surface treatment agent of silicon steel plate.
3.used for boiler feed water system and steam generation system cleaning and descaling.
4. It is used for acidizing the surface of oilfield sand and stone. During formation acidification in oilfield, ammonium hydrogen fluoride is added to hydrofluoric acid to produce hydrofluoric acid, which is indirectly combined with hydrochloric acid to form soil acid. When this kind of soil acid treats limestone, due to the formation of a protective layer of calcium fluoride insoluble in hydrochloric acid on the pore surface, the dissolution rate of rock is significantly reduced, and the depth of acidification is increased. When dealing with sandstone, it can prevent the production of fluorosilicate caused by hydrofluoric acid, and at the same time enhance the ability to dissolve silicates and wall mud, and improve the acidification effect. It also reduces corrosion of surface equipment and pipelines.
5. used in electronics industry, Braun tube (cathode picture tube) cleaning agent.
6.used in the production of incandescent lamp, bulb inner surface matting agent.
7. used as alkylation, isomerization catalyst components.
8.used as cryolite production intermediate.
9.used as wood protective agent, preservative.
10. used as a catalyst in electroplating, reaction to produce white material anode mud.
11. for aluminum profile surface acid etching treatment, the formation of fluoride protective layer on the surface.
12. used for manufacturing magnesium and magnesium alloy, manufacturing aluminum magnesium alloy oxidant.
13. can remove the alkali residue on the fabric after washing, but also with iron to produce colorless soluble ammonium ferric fluoride, can be used to remove rust on the fabric.
14.used as an analytical reagent and bacterial inhibitor.
15.used as a reagent to extract rare elements.
16. Leaching cobalt from iron ore tailings with citrate and ammonium hydrogen fluoride.
17. used for making welding rod, cast steel, etc.
18.can be used as a hidden reagent of trivalent iron ion.
19.fiber mordant.
20. Used in the manufacture of ceramics.
21.used for organic synthesis fluorination agent.
22. Electronic grade ammonium hydrogen fluoride can be used in the semiconductor industry.
23. Preparation of hydrogen fluoride in the laboratory.
24. In oil production, ammonium hydrogen fluoride is used to dissolve silica and silicates.
While ammonium bifluoride has various practical uses, it is important to note that it is a hazardous substance and should be handled with care. It is corrosive to the skin, eyes, and respiratory system, and proper safety precautions must be followed when working with it.
