G-CLEAN 247: CITRIC ACID BASED PASSIVATION AGENT (0% VOC)


 
PROCESS:



Manufacturing of hydraulic wheels for hydroelectric turbine dams.
The last step in the manufacturing process is the passivation of stainless steel (martensitic 410) protecting the hydraulic wheel from rust.


 
EXISTING PROCEDURE
 
PRODUCT USED:


High toxicity passivation agent
Contains: Nitric acid
Nitric acid is a highly corrosive product which may cause major and deep skin burns


 
 
CLEANING PROCESS:


The passivation agent is sprayed on the hydraulic wheel, using a water hose, for a period of one hour. This procedure must be performed at night or on weekends in order to prevent nitric acid accidents.

 
 
REASONS FOR CHANGE:

Reduce the risk of accidents
Reduce the product toxicity

 
NEW PROCEDURE
 
PRODUCT USED:
