Aqueous Alkaline Degreasing is a process we use for pretreating the metals prior to the pickling and passivation processes. This process deep cleans the part from all types of oils, waxes and greases, as well as many other contaminants known to be found on metals after machining and production.
Alkaline cleaning is an age-old process which has been used extensively in the metal finishing industry. The aqueous degreasing processes involves less toxic properties than that of vapor degreasing. The properties associated with alkaline cleaners (nonvolatile, nontoxic, noncombustible, and biodegradable) make them environmentally acceptable alternatives for use in cleaning metal contaminants that could possibly affect the parts integrity.
Alkaline cleaners are able to achieve cleaning efficiencies comparable to organic solvents. Cleaning enhancements including agitation, immersion, spray washing and ultrasonics can help improve cleaning efficiencies for heavier oils and greases.
The alkaline aqueous degreasing process is perfect for removing contaminates from lightly soiled metals by immersion with air agitation. Heavier soiled parts are also sprayed from specialized equipment to more effectively loosen heavier contaminants on soiled metals.
All-in-all this metal cleaning process is similar (except for the cleaning agents used) in nature to vapor degreasing and just as effective. Call us at Electro-Max and ask how our alkaline cleaners can help your metal finishing needs.
