■ Performance Brief

Anhydrous Hydrogen fluoride at low temperature is a pourable Colorless transparent Liquid, at room temperature and atmospheric pressure is volatile and moist air in contact will generate thick smoke and irritating odor. There are some metal material corrosive effect of flammable non-explosive.

■ Uses

Mainly for the production of fluorine refrigerant, fluoride, cryolite and aluminum fluoride secondary, is the only element in the preparation of fluorine materials, fluorine rubber industry is an important raw material and production of organic fluoride, in the production of high-octane gasoline as a catalyst. it also can be used as glass etching and metal cleaning agent. it is also a solvent separation of rare metals zirconium, tantalum and the like.

■ packaging, storage, transport

Anhydrous Hydrogen fluoride packaged in a clean, dry dedicated tank or steel cylinder. Packaging container having a liquid gas import and export, filling coefficient 0.83KG / L, steel cylinder coated with gray paint and a black belt, and with a safety shockproof cap and apron.
Each batch of Anhydrous Hydrogen fluoride shall be accompanied by product certification, including: production factory, the product Name, Batch No., Code No. standard and inspectors on behalf of the No ..
When steel cylinder shipment should follow the "Gas Cylinder Safety Supervision" and "Dangerous Goods Code" requirement.
Manufacturer name should be marked on the steel cylinder, Product Name, date of production, level, batch No. and Net wt.
Anhydrous Hydrogen fluoride steel cylinder should be stored in a warehouse with a shed, non-exposure, exposure is strictly prohibited and flammable products.
