CLEANER MS 114 

Cleaner  MS - 114 is a non silicated, mild alkaline soak  cleaner for aluminium base  die-castings  and other  reactive  metals fo aluminium. The cleaner can be used for either non-etch cleaning or mild  etch  cleaning by varying  the  concentration,  temparature etc., as indicated below. 

Cleaner MS - 114 has excellent detergency properties and  rapidl removes  light soil and light buffing compounds. The  cleaner  is ideal  for  non-etch  cleaning of aluminum  prior  to  anodising, chromating bright dipping and electroplating. 

Operating conditions :  

For non-etch cleaning

Concentration              20-50 gm/lit.

Temperature                50-60* c.

Time                           2-5 minutes  

For mild-etch cleaning

Concentration           40-65 gm/lit.

Temperature             65-85* c.

Time                        2-5 minutes  

Operation :

The work to be cleaned is simply immersed in the cleaner for  2-5 minutes. In case of mild-etch cleaning a light smut will form  on the surface of the aluminium. Aluminium alloys containing a  high percentage  of copper or silicon, form a dark smut-which  can  be removed in 50 % volume nitric acid.  

Equipment :

A stainless steel tank with S.S. heater is recommended.  

Maintanance :

The  concentration  of  cleaner  MS - 114  can  be  controlle  by titration  with  n/10  hydrocloric acid using methyl  red  as  an indicator.  Required pointage is 14 ml of n/10  hydrocloric  acid against  5 ml bath solution. When heavy accmulation of sludge  is formed at the bottom,it should be removed.when cleaning action is not  within the time even after adding required amount of  MS-114 as per the pointage, the bath is to be discarded.
