Sodium hydrogen difluoride is our advantageous product

Sodium hydrogen difluoride is one chemical product of fluoride series. The Sodium hydrogen difluoride pellets is white pellets. Sodium hydrogen difluoride pellets is soluble in water and is corrosive to tissue. We export the Sodium hydrogen difluoride pellets to USA, Germany, France, South Africa, UK, Australia, Vietnam and so on. It is our advantageous product.

What are uses of sodium hydrogen difluoride?

The sodium hydrogen difluoride is generally soluble in water, but insoluble in alcohol. The resulting solutions contain moderate concentrations of hydrogen ions and have pH’s of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.

The sodium hydrogen difluoride pellets has strong sourness. In humidity air it absorbs moisture and releases hydrogen fluoride. When heated to 160? it decomposes into sodium fluoride and hydrogen fluoride. At high temperature aluminium and aluminium alloy can resist the corrosion of hydrogen fluoride. Its aqueous solution can etch glass. It is toxic.

It is used as aseptic of food, animal specimen and dissection specimen, as glass etchant, in glass frosting, for texture finishing of textile, in wiping off rust, in insect proof treatment of leather, as the material for tinplate, and to produce anhydrous HF. Its mixture with potassium hydrogen fluoride can be used as flux of metal.
