The immersion time required for cleaning depends upon the amount of contamination, concentration and temperature. Bath should be maintained at the recommended pointage and temperature. Product Application EquipmentsKemklin-102 tank should be lead lined, rubber lined, glass fibre, rigid polythene, stainless steel tanks made out of 18 guage sheets preferred. Steam coil or heaters should be lead or 316 SS. Testing and Control Procedure Pipette out 10 ml. of the bath solution and add 90 ml. of water to itPipette out 10 ml. of diluted solution in a conical flask and add 2-4 drops of methyl orange indicatorTitrate it with N/10 Sodium Hydroxide solutionThe colour changes from red to yellowFreshly prepared 25% concentration kemklin-102 solution give the reading of 20-25 ml. Iron ConcentrationPipette out 10 ml. of bath solution, and add 10 ml of 50% concentrated sulphuric (H2SO4) acid. Mix it thoroughly, titrate this against N/10 potassium permanganate (KmnO4) solution till the pink colour persists for 15 seconds. % of iron is to be calclated as Burette reading X 0.056. Maximum permissible limit of Iron in Kemklin-102 bath is 7% Chemical ReplenishmentThe bath should be discarded when addition of concentrated solution and increase in the temperature does not show faster derusting action and powdery deposits appear on the surface of the metal.
