I was in charge of debunking phony claims of right wing trump stooges on the internet. one guy claimed he worked on the Space Shuttle, and it turned out he was in charge of mopping the floors at an adult movie theater.
really they put a moron like you in charge.
well goober I did work on the shuttle and other programs.
I worked both in the field and in the clean room which In was in charge of.
we would get a pipe a line or part such as a valve in the shop.
the process varied according to specs,but in general I would first do a ultrasonic process on the smaller part in DI water, next I would dry it with nitrogen doers . next came a passivization which is basically running a acid inside the think to remove and particulars of iron on the surface and it also left a coating on it to help prevent corrosion and cross contamination some time we did a ultraviolet test also. Next would come a flow of freon , this removes any oil or chemicals and also picks up particulate.
After the freon was collected I would do 2 tests on it. One involved dumping one sample on a special filter that varied in size according to the specs any where from 200 microns to 5 microns generally . then I would place the filter under a microscope and measure the size of any thing in it.
The next test was to weigh a small thin metal container about the size of a votive candle base ,this was done with a very good and expensive scientific scale. then the sample was placed in it and placed in a vacuum chamber that was heated and pulled down to negative 15 psi . then after the sample had evaporated it was placed on a scale , the difference between the empty tray and the evaporated tray told us how much oil was or other compounds were in the sample. if all passed the part was next dried with nitrogen.
then it was placed in a mylanar bag with a small amount of a a nitrogen purge and head sealed , I them put my label on it certifying it for use with NASA , logged the info in on our log and cert book. and it was ready to be shipped or delivered.
Ill post more for you to debunk goober but thats enough for tonight
