Kemclean-K-12
(Alkaline Degreasing Compound)
Product Description
Kemclean-k-12 is a heavy duty and efficient caustic-free dip alkaline
cleaner used for degreasing of ferrous and non-ferrous metals. It
contains an optimum blend of chemicals to obtain a superior metal
cleaning action. Kemclean-K-12 has also a long working life. Because
of the presence of efficient detergents and sequestering agents, the
kemclean-K-12 can be quickly rinsed from the components after
degreasing.

Product Operating Procedure
Fill the Kemclean-K-12 tank with 2/3
of water and heat it upto 45°C. Add 5 kgs of Kemclean-K-12
powder in 100 ltr. bath with continuous agitation till the chemical
completely dissolved. Fill the tank to the operating level and raise
the temperature. Stir the bath and draw bath sample for the
determination of pointage.
Strength of kemclean-k-12 bath can
be increased if the components are heavily contaminated with heavy
oil or grease. It is therefore advisable that heavily contaminated
components should be pre-dipped in soak cleaner or emulsion cleaner
which may help to remove the oil/grease from the surface of the
components with in every short time, ultimately pre-dip cleaning will
also help to increase the life of the degreasing bath. Maintenance of
the temperature is also very important factor. If the temperature of
the bath is low the efficiency of the degreasing chemical will be
effected even if the concentration and the treatment time are
increased. The components should be thoroughly rinsed with over
flowing system until unless Kemclean-K-12 is completely removed.
Product Application Equipment
Kemclean-K-12 tank should be fabricated with 3 to 4 mm thick M.S.
Plates with continuous agitation arrangement from a heating unit.
Testing and Control Procedure
Pipette out 10 ml. Of the bath solution in a conical flask. Add 2 to 3
drops orange indicator. Titrate against N/10 sulfuric acid till the
colour changes from yellow to red. The burette reading is the
pointage. The pointage of the degreasing should always be maintained
at the recommended level.
Chemical Replenishment
The efficiency of the degreasing
bath falls due to the carry over of oils coming from work which gets
emulsified in the bath solution and presence of the sludge at the
bottom. At this stage Kemclean-K-12 bath should be discarded.
Safety Measures
Kemclean-K-12 contact with skin,
eyes, mouth and clothing should be avoided and proper safety
precautions should be taken by the operators by using gloves, goggles
and safety clothing.
