Clean and Bake batch 9 |
|
|
| Bagged and Tagged the reflector arms and bases and placed them inside the clean room. Total of 2 bags used. Cleaned and Baked parts in batch 9 on the spread sheet and used the following procedure;
1. Ramp to 100 degC in 15 min.
2. Dwell at 100 degC for 30 min.
3. Ramp to 200 degC in 30 min.
4. Dwell at 200 degC for 48 hours.
5. OFF
Also soaked the 2.75" CF gate valve in acetone to try and clean the open threads around the part. Then cleaned it in the ultrasonic washer with liquinox for 20 minutes (10 minutes each side). It looks better than it used to but the threads still seem to be the problem and will probably need even further cleaning. |
