Our above product is specially designed in an acidic powder form to remove water scale deposits effectively without endangering the base metal. It is a thoroughly inhibited composition which offers easy handling and safety for both personnel and equipments. It has negligible effect on skin and clothing. Eyes, however should be protected and for safety’s sake we advice us of goggles and gloves while dissolving in water. Cleaning is fast without fuming and there is no localised etching or corrosion as it happens in case of using hydrochloric acid.
Solution strength should be kept between 5 to 10% of SCALGUN SAF POWDER i.e. 5 to 10 kgs dissolved in 100 litres of water. Strength of solution and time of descaling depends upon the thickness of scale deposits to be removed. It is recommended for ferrous metals or stainless steel equipments.
Appearance : Dry Acid Powder
pH of 1% solution : 2 ±0.5
Solution should be heated upto 160°F. The solution should be circulated at high rate for more effective descaling, particularly when equipment is badly fouled. This keeps fresh strong solution in contact with the scale.
6 to 8 hours and then the system should be flushed off with water.
EQUIPMENTS FOR CLEANING:
Steam line jet ejectors provide heat as well as circulation. They are inexpensive and simple. A portable high output pump is used when tubes are badly clogged. A big size PVC or rubber hose is required for connection the lines. It is advisable to clean the tubes first with alkaline chemical like ASFOCLEAN-240 which will remove some loose deposits of iron along with organic residues so that the subsequent cleaning is made more effective.
ASFOCLEAN-240 should be used 2-3% preferably hot at 70°C to 80°C by heating with direct steam injection. This operation is done only wherever necessary particularly for cleaning of condensers or heat exchangers.
For removal of mineral oil sludges, we recommend you to use our EMULSOIL-PLS by soaking at room temperature for an overnight followed by flushing with water after draining EMULSOIL-PLS. For removal of fatty acids/oil sludges based on vegetable oils, we recommend you to use our ASFOCLEAN-A 5 to 10% solution at boiling temperature. Then flushing is followed with plain water.
Above chemical cleaning is much safer, more effective and time saving. Simple protective equipments are necessary.
