The purpose of this experiment was to perform a 60-minute heated immersion test on Mirachem 500 using Contaminant #4. Test requested by company.
A solution of Mirachem 500 was prepared to a concentration of 25% and heated to 120°F. Three glass coupons were obtained and an initial weight was recorded. Coupons were then soiled with Rosin #4 and a dirty weight was recorded. Once the cleaning solution reached the proper temperature, coupons were submerged into the beaker for 60 minutes with observations recorded at 5, 15, 30 and 60 minutes. Coupons air-dried for 24 hours and a clean weight was recorded. The effectiveness of the cleaner was determined.
|Cleaner||Initial wt of cont||Final wt of cont||%Cont Removed||%AVG||Observations|
|Mirachem 500||0.1047||0.0101||90.35||64.44||5: Soil still present, slight dissolve|
|0.1953||0.0857||56.12||15: Some dissolving on all coupons|
|0.2883||0.1532||46.86||30: Soil slowly dissolving|
Coupon 1: Almost all soil gone,
Coupon 2: Some soil removed,
Coupon 3: Little soil removed
Success Rating:Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
Mirachem 500 removed an average of 64.44% of soil from glass coupons via heated immersion.
