BetzDearborn Kleen 133- Alkaline Etching Cleaner for Aluminum
- Strong alkaline cleaner
- Effective on steel in both spray and immersion applications
DESCRIPTION AND USE
BetzDearborn Kleen 133 is a strong, powdered alkaline cleaner for use in spray or immersion applications.
It will remove a wide variety of soils from fabricated steel and other ferrous metals. Kleen 133 will produce minimal foam.
SUMMARY OF OPERATING DATA
Cleaner Bath Makeup
For each unit volume of bath, add the appropriate amount of Kleen 133 to the water while stirring or with the pump circulating.
Note: Dissolve Kleen 133 in a pail of water before adding to the cleaner bath; slowly add Kleen 133 to the pail of water while stirring. Failure to dissolve the product will cause a low free alkalinity titration and is not economical.
Normal Operating Controls
Free Alkalinity Titration: 6 to 12 mL
Temperature
spray: 130 to150°F
immersion: 110 to 150°F
Treating Time:
spray: 45 to 90 sec
immersion: 2 to 5 min
Nozzle Pressure
spray: 15 to 30 psi
MAINTENANCE OF THE BATH
The Kleen 133 bath is controlled by the free alkalinity titration as provided in procedure AP311.
The cleaner bath should be replenished based on the free alkalinity titration by feeding Kleen 133. The free alkalinity titration should be maintained within the control range specified by BetzDearborn. For each 1 mL of free alkalinity lacking, add 0.78 lbs of Kleen 133 per 100 gal of bath.
The feed of Kleen 133 can be automated through the use of BetzDearborn AccuTrak conductivity control.
The bath should be overflowed or diluted in order to keep total alkalinity (AP281) below the value specified by your BetzDearborn representative.
OPERATIONAL RECOMMENDATIONS
- If the work is heavily soiled and additional cleaning power is needed, a BetzDearborn Solv additive can be added to the cleaner bath. A BetzDearborn representative will recommend the proper Solv and the correct use concentration.
- If foaming occurs in the cleaner bath, the temperature of the bath may be too low. Raising the temperature of the bath will usually reduce foaming. The temperature of the bath should not exceed 160°F.
- The initial charge and replenishment data contained herein are normal for most installations; however, a BetzDearborn representative may suggest a deviation from this data, if indicated by local conditions.
EQUIPMENT
The tanks for the Kleen 133 bath may be constructed of mild steel. Auxiliary equipment can also be constructed of mild steel.
