Client #215

Project Number 1

Summary:

Initially, eight cleaners were selected from the laboratory's database of cleaning evaluations. Based on client input, five cleaners could be used as a cold solvent, requiring no rinsing and leaving no residue. The successful products were used to clean supplied parts. Upon review by the client, cleaning was not acceptable. Additional testing on drop-in vapor degreasers were conducted. Parts were cleaned and analyzed by the client. This time the parts were acceptable. Only obstacle is cost of drop-in solvents.

Test Objective:

Explore alternative processes and chemicals

Product Use:

various tools

Trial Number	Date Run	Purpose	Success Rating
0	09/12/2003	To evaluate cleaners for removal of quench oil	Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
1	09/15/2003	To reevaluate partially successful products under heated conditions	A follow up test, usually based on company input.
2	09/15/2003	To evaluate successful cleaners from previous trials on second contaminant	Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
3	09/16/2003	To retest four products utilizing longer cleaning time	A follow up test, usually based on company input.
4	09/19/2003	To evaluate the eight cleaners on the final contaminant	A follow up test, usually based on company input.
5	09/22/2003	Reevaluate top three cleaners on supplied varnish.	A follow up test, usually based on company input.
6	01/22/2004	To evaluate effective cleaners on supplied parts.	A follow up test, usually based on company input.
7	01/22/2004	To evaluate cleaners on second supplied parts using immersion cleaning	A follow up test, usually based on company input.
8	01/22/2004	To evaluate ultrasonic energy for cleaning the supplied parts.	A follow up test, usually based on company input.
9	01/23/2004	To evaluate selected cleaners on third supplied part	A follow up test, usually based on company input.
10	01/23/2004	To evaluate cleaners from previous trial at extended cleaning times	A follow up test, usually based on company input.
11	05/05/2004	To evaluate TCE drop-in replacements for vapor degreasing operation.	Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
12	05/06/2004	To evaluate successful products on second supplied contaminant	Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
13	05/07/2004	To evaluate successful products on third supplied soil	A follow up test, usually based on company input.
14	05/11/2004	To conduct a preliminary evaluation of vapor degreasing on a supplied oil	Results suggest a scale-up feasible match for cleaning chemistry and equipment. Pilot plant study with actual parts recommended.
