APPLICATION PROCEDURE
Preparing Solutions: Add the total required quantity of Aluminum Cleaner 164 to half the volume of water,
cold, while stirring and heat to about 180°F (82 °C). Then, add the remaining half of water and adjust solution
to operating temperature.
Aluminum Cleaner 164 is normally used at a 45 – 75 g/l (6 – 10 oz/gal) of water and in the temperature range
of 120° – 180 °F (49° – 82 °C). It may be used in air-agitated tanks without foaming excessively.
SOLUTION CONTROL
Concentrations are titrated using Gardotest Procedure 92 or Gardotest Procedure 123.
For concentrations use Gardotest Procedure 92.
Sample Size: 25 mL
Factor: 1.0
For free or total alkali use Gardotest Procedure 123. (See Procedure)
EQUIPMENT
The Chemetall Electrodeless Conductivity/Concentration Control System and Chemical Metering Pump can
be used to monitor and automatically maintain the concentration of this product using conductivity. Please
contact the Chemetall Process Equipment and Engineering Department for specific recommendations.
