Performance Brief:

Anhydrous hydrogen fluoride in the colorless transparent liquid is a low temperature flowable, highly volatile in contact with moist air will generate a thick smoke and irritating odor at room temperature and atmospheric pressure. Corrosion of metal materials have some non-flammable effects.

Usage:

Mainly for the production of fluorine refrigerant, aluminum fluoride and cryolite secondary fluorides, fluorine is the only preparation of raw materials, and industrial production of organic fluorine rubber fluoride important raw material in the production of high-octane gasoline As a catalyst. It is also used as a glass etchant and metal cleaner. It is also a solvent that separates rare metals such as zirconium and tantalum.

Packaging, storage and transportation:

Anhydrous hydrogen fluoride is packaged in a clean, dry, dedicated tank or cylinder. Liquid packaging container having a gas export, filling coefficient 0.83KG / L, cylinders coated with a gray and black paint, and a helmet with a shock and apron.

Each batch of anhydrous hydrogen fluoride should be accompanied by a product certification, including: the manufacturer name, product name, batch number, standard number and inspector code.

Cylinders shipped, should be consistent with "gas cylinder safety supervision regulations" and "dangerous goods transport rules" requirements.

Cylinder should be marked on the manufacturer name, product name, date of production, level, lot number and net weight.

Anhydrous hydrogen fluoride cylinders should be stored in shed with a warehouse, no exposure, non-flammable and easy to be exposed.
