Feature:
Hydrofluoric acid is aqueous solution of hydrogen fluoride. It's colorless and transparent, having strong and irritative smell and causticity. It can pickling such materials containing SiO 2 as glass quickly. Hydrofluoric acid can’t undergo the reduction reaction and oxidation reaction.With deadly poisonous.
Application:
It's widely used in national defense and civil industry, and it is a base product in fluoride industry, It can produce fluoride, freon, fluoroplastics and alky lation contact agent in atomic energy and semiconductor industry. It is also used in metallic surface treatment, glass etching, ceramics treatment and element F production.
Packing:
Packing with polyethylene plastic drum (200kg each drum).
Store:
Store in a cool, dry, well-ventilated storehouse, indoor temperature is below 30°C, relative humidity is below 85%.
