Ammonium Bifluoride Action And Use

1.used as glass matting, frosting, etching agent (often used with hydrofluoric acid).
2.used as chemical reagent, fermentation industry disinfectant and preservative, beryllium oxide metal beryllium solvent, and silicon steel plate surface treatment agent.
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 gravel. In the formation acidification of oil field, 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 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 the rock is significantly reduced, the depth of acidification is increased, and the treatment of sandstone can prevent the production of fluorosilicate caused by hydrofluoric acid, while enhancing the ability to dissolve silicates and wall mud, improving the acidification effect. It also reduces the corrosion of ground equipment and pipelines.
5. used in electronics industry, Braun tube (cathode picture tube) cleaning agent.
6. used in the production of incandescent lamps, light bulb interior matting agent.
7. used as alkylation, isomerization catalyst components.
8. used as an intermediate for cryolite production.
9. Used as wood protective agent and preservative.
10. used as a catalyst in electroplating, reaction to produce white material anode mud.
11. It is used for acid etching on the surface of aluminum profiles to form a protective layer of fluoride on the surface.
12. for the manufacture of magnesium and magnesium alloy, the manufacture of aluminum magnesium alloy oxidant.
13. can remove the alkaline residue on the fabric after alkali washing, but also with iron to produce colorless soluble ammonium ferric fluoride, can be used to remove the rust on the fabric.
14. used as an analytical reagent and bacterial inhibitor.
15. used as a reagent to extract rare elements.
16. citrate and ammonium hydrogen fluoride leach cobalt from iron ore tailings.
17. used to make welding rods, cast steel, etc.
18. can be used as a hidden reagent of trivalent iron ions.
19. fiber mordant.
20. for 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 recovery, ammonium hydrogen fluoride is used to dissolve silica and silicates.
