Product Operating Procedure
Make 0.15 – 0.2% solution in water. provide air agitation continuously as the chemical is totally insoluble in water. Check pH of the solution
Product Application Equipment
Kemphos-338 tank should be fabricated with 3 to 4 mm thick M.S. Plates with continuous convection current hating system.
Testing and Control Procedure
Kemphos-338 bath strength can be easily controlled by determination of pH value of the bath solution directly.
Chemical Replenishment
Restore the bath to the working level by adding water to makeup evaporation loss and drag out losses. Chdck the Kemphos-338 solution pH. Add 100 gm Kemphos-338 powder per 100 ltr. Bath to increase pH by one unit.
Safety Measures
Kemphos-338 is an alkaline material. Direct contact causes irritation of skin, wash thoroughly, do not take it internally.
General Information
With the use of surface activation chemical, the phosphate quality gets enhanced and its structure becomes more compact.
