BRIEF DESCRIPTION

Ammonium bifluoride, also known as ammonium fluoride, is an inorganic compound with white or colorless transparent orthorhombic crystals. It is a corrosive chemical substance with the molecular formula NH4HF2.

TECHNICAL INDICATORS

USE

1）. Industrial application

1.Electroplating industry

In the electroplating process, ammonium bifluoride can be used as an etchant and catalyst. It can accelerate the corrosion reaction on the metal surface and make the plating more uniform and stronger.

2.Glass industry

During the glass manufacturing process, the glass surface needs to be pickled. Ammonium bifluoride can be used as a pickling agent at this time, which can effectively remove stains on the glass surface.

Dirt and impurities.

3. Printing industry

During the printing process, a printing plate coating is required to make the printing plate. At this time, you can use a coating agent containing ammonium bifluoride to form a micro-layer on the surface of the printing plate.

Small and uniform grooves, resulting in high-quality printing results.

4. Chemical reagents

Due to its strong corrosiveness and stability, ammonium bifluoride can be used as an important chemical reagent. It can be used to prepare other chemical reagents such as calcium fluoride,

Aluminum fluoride, etc.。

2）. Medical applications

1. Dental treatment

Ammonium bifluoride can be used in dental treatments. It can strengthen the hardness of tooth surface and prevent tooth decay and tooth sensitivity.

2. Disinfectants

Due to its strong bactericidal effect, ammonium bifluoride can be used as a disinfectant. It can effectively kill microorganisms such as bacteria, viruses and fungi, thereby keeping the environment clean

Cleanliness and hygiene.

3. Pharmaceutical preparations

In some pharmaceutical preparations it is necessary to use compounds containing fluoride ions. At this time, salts containing fluoride ions can be used, such as sodium fluoride, ammonium fluoride, etc. Among them, fluorination

Ammonium is a common pharmaceutical excipient and is widely used in heparin drugs.

STORAGE CONDITIONS

1. Store in a cool, dry and ventilated warehouse.

2. Keep away from fire and heat sources.

3. Store in a sealed container and keep away from children.

4. It should be stored separately from acids to prevent it from reacting with acidic substances.

5. Store separately from food chemicals, avoid mixed storage.

6. The storage area should be equipped with suitable materials to contain leaks.

7. Wear protective glasses, gloves and protective clothing during operation.

PACKAGE

1. The inner layer is a polyethylene plastic bag and the outer layer is a woven bag, 25kg/bag

2. Other forms of packaging according to customer needs

CHEMICAL PROPERTIES

Ammonium bifluoride aqueous solution is weakly acidic, can dissolve glass, is slightly soluble in alcohol, is easily soluble in cold water, and is very easy to deliquesce. It has a slightly sour smell, is corrosive, and is easy to deliquesce. It is weakly acidic when soluble in water, and is slightly soluble in water. Soluble in ethanol, easily soluble in cold water, decomposes in hot water, and the aqueous solution is slightly acidic. poisonous!
