Potassium Ferricyanide Papers in Pakistan

Product Description:

Potassium Ferricyanide Test Papers will detect iron salts that form at the bottom of rust pits on blast-cleaned steel.

If these iron salts are present, they rapidly induce corrosion.

The test involves the reaction of soluble ferrous iron salts with potassium ferricyanide to form ferric hexacyanoferrate, which is commonly known as Prussian blue.  The relatively high tinting strength of Prussian blue enables the reaction to be used as a very sensitive test on ferrous irons.

Supplied in packs of 100 Papers.

Technical Specifications:

Spray a film of Deionized Water on an area of the blast-cleaned steel.  The Test Paper is then held against the surface for approximately 10 seconds.  Any soluble iron salts present are drawn out of the rust pits by capillary action and react with the potassium ferricyanide to form blue spots.  The presence of blue spots on the Test Paper indicates that the surface should be re-blasted.

We would recommend that the Test Papers be used within a 6-month period from the date of purchase.
