Technical specifications
It is a liquid formulation based on inorganic acids and special corrosion inhibitors. Disintegrating agent for cement deposits. FIPRODISK 102 is a liquid product for dissolving inorganic deposits of a calcareous nature in pipes or heat exchangers. FIPRODISK 102 removes and cleans walls of such deposits without attacking the metal part.

Usage and Applications
FIPRODISK 102 is used in a 5 to 20% aqueous solution. At this concentration it can be kept in circulation for at least 4 to 5 hours for cleaning.
The concentration of use depends on the amount of carbonate to be dissolved.
Theoretically 1 kg. of FIPRODISK 102 is capable of removing 0.55 kg. of calcium carbonate at 20°C.
For descaling injection pipes soiled with cement, proceed as follows. Prepare approx. 200 litres of 20% FIPRODISK 102 solution in an acid-resistant container. Make a split circuit so that the descaling solution can be recirculated (the FIPRODISK 102 solution fed into the pipes to be descaled returns to the container from which it is pumped back into the circuit). The duration of the treatment depends on the thickness of the encrustations and the speed of the descaling liquid. Generally speaking, the time required is between 30 and 60 minutes.
.After treatment, provide a thorough rinse with disposable water. The descaling solution must be neutralised with soda lime to pH 7-8 before being discharged.
After completion of the descaling treatment, the circuit must be drained and rinsed.
After the rinsing phase, an appropriate passivating agent must be used to neutralise and form a protective film on the metal wall. If necessary, the amount of FIPRODISK 102 present in the solution can be determined by titration.

Controlling the solution
Take 10 ml of the titration solution and place in the Erlenmeyer flask
. Add 5-6 drops of Methyl orange indicator. The solution will turn a deep red colour
. Titrate with sodium hydrate 1 N until the solution is a persistent yellow colour
To obtain the concentration in g/lt multiply the value obtained by the fixed number
Highlights
Effective against all types of oxide or salt deposits
. Inhibited, therefore does not give rise to corrosion in the treated system
Applications
Water circulation circuits (exchangers, boilers)
. Greasing tanks
Phosphorous degreasing lines
