Product Type: Freiclean 56KN
   

FREICLEAN 56KN is a liquid, alkaline heavy-duty immersion cleaner for steel. FREICLEAN 56KN is designed to remove phosphate and lubricant soils from steel work. FREICLEAN 56KN has over 4 times the reactive lubricant holding capacity of FREICLEAN 56 and FREICLEAN 56N.

FREICLEAN 56KN is a liquid, alkaline heavy-duty immersion cleaner for steel. FREICLEAN 56KN is designed to remove phosphate and lubricant soils from steel work. . FREICLEAN 56KN has over 4 times the reactive lubricant holding capacity of FREICLEAN 56 and FREICLEAN 56N.

FREICLEAN 56KN may be used at concentrations of 5-15% by volume with operating temperatures of 150-200°F. The normal processing time is 3-10 minutes for immersion. For optimum removal of heavy phosphate coatings, a concentration of 10% by volume at 190°F with immersion time of 5 minutes or more is recommended.

Free Alkali:

The concentration of the FREICLEAN 56KN solution may be determined by the Free Alkali
titration as follows:

Pipette a 2 ml sample of the FREICLEAN 56KN solution into a suitable beaker or
Erlenmeyer flask and add 4 drops of Indication Solution 3 (Phenolphthalein). Titrate the pink solution with Testing Solution 20 (0.1 N H2SO4) until the pink color is just removed from the solution. Record the number of milliliters of Testing Solution 20 used as the Free Alkali Points.

Concentration (% v/v) = (Free Alkali Points) x 0.735 = (mls Testing Solution 20) x 0.735

A FREICLEAN 56KN solution prepared at 10% by volume will have a titration reading of
approximately 13.6 points Testing Solution 20. Addition of 7.3 gals (81 lbs.) of FREICLEAN 56KN per 1000 gals will raise the titration by 1 point.

Total Alkali:
The ratio of Total Alkali to Free Alkali can give an indication of when the cleaning solution should be discarded. The Total Alkali is determined as follows:

Pipette a 2 mL sample of the FREICLEAN 56KN solution into a suitable beaker or
Erlenmeyer flask and add 2-3 drops of Indicating Solution 8 (Methyl Orange-Xylene Cyanol Complex) and titrate the sample with Testing Solution 20 (0.1 N H2SO4) until the green color turns purple.
