Compounds
are critical and in many cases more importance in obtaining processes
and finishes in mass finishing than the media itself.
Compounds
accomplish many things:
- Lubricates
the mass resulting in extended media life.
- Cushions
the part eliminating part damage.
- Suspends
the dirt, oils and media residues and flushes them from the system
keeping the parts and media clean.
- Inhibits
rust or corrosion of parts in the finishing process. Extended
shelf life inhibiting should be done as a post dip or spray with
water soluble inhibitors.
- Burnishing
- Descaling
- Accelerates
media cut
Compounds
are identified in the following categories. Some compounds will do
multiple functions.
- Deburring
compounds (General Purpose)
- Burnishing
compounds (Brighting)
- Rust
inhibitors (Post operation sprays or dips)
- Descalers
Compounds
are critical and in many cases, more important in obtaining processes
and finishes in mass finishing than the media itself.
Compounds
in some cases can be mixed with water and then flowed through the
system. The compound and water in many cases can pass straight to the
sewer. However in some machines the compounds are recirculated back through the system after being filtered.
The
general compound concentration and water flows are 1 to 2 oz per
gallon of water and 1 to 2 gallons of water per cubic ft per hour,
depending upon water hardness.
