1 - 8 Installation, Operations, and Maintenance Manual
The MART Corporation Standard Turntable Power Washer v. 4.0
In terms of results, wet grit blasting means that the dirtier the power washer gets, the
faster it cleans. This feature is desirable for most rebuilding applications and some
manufacturing ones.
3.1.2. Temperature
As temperature increases, greases and oil become more fluid; in other words, their
viscosity decreases. Since grease is the primary binder that holds and contains the
soils on the parts, higher washing temperatures above 160
°
F (71
°
C) generally produce
better cleaning results.
Secondly, chemical is more aggressive at higher temperatures. As a general rule, for
every 10
°
F (-12.22
°
C) rise in temperature above 160
°
F, a chemical reaction doubles
in speed.
3.1.3. Chemical
Chemical is the third key factor in overpowering soils and removing them from the
surface of parts. While chemicals are necessary to enhance the cleaning process, your
MART Power Washer does not rely primarily on chemical concentration. This is
because your MART sales technician worked with you to determine your cleaning
needs, such as:
·
Required degree of cleanliness
·
Nature of the soils to be removed
·
Pump size and performance requirements
· Size, shape and surface of the parts to be cleaned
· Applications and usage of the power washer in your shop
Because your MART Power Washer's configuration has been customized specifically to
meet your requirements, the washer will successfully meet your cleaning standards
when charged with a
light chemical concentration, as compared to conventional
washers. In general, this means that a 2-5% concentration by volume of a quality non-
foaming chemical compound will give excellent cleaning results. However, like
temperature and power, the exact type and amount of chemical are subjective and
depend on your shop's needs.
Chemical cleaners fall into three general categories:
· Organic solvents
·
Emulsion cleaners
·
Aqueous (water-based) alkaline cleaners
MART systems use an aqueous (water-based) alkaline cleaner , not a solvent, so you
don't have to deal with solvent vapors or hazardous-waste contaminants. Generally, the
