Use and Function:Hydrochloric acid is an important chemical material used in water treatment, chemical, metallurgy, light industry, textile, dyeing, medical, food, printing, leather field. Hydrochloric acid can dissolve metallic oxide and carbonate incrustation quickly. Therefore it is widely used for rust cleaning and incrustation cleaning.
Packing: The product is packed by POLY drum or ceramic package. ‘Hydrochloric acid’ and ‘Corrosion’ signs should be posted out of package.
