Inquiry (采购产品): Quote Request We have a lot of 3 copper radiation shields for vacuum insulated liquid nitrogen Dewars which would benefit from polishing to minimize their emissivity. They are cylinders with a diameter of 16" and a length of 12". One end is closed with a 1" diameter extension of 8" length. Total length is therefore 20". Each shield has a seprate end cap which would also be polished. The shields are fabricated from 0.03" thick copper sheet with soft solder, SnPb, joints. Please provide a budgetary quote for electro-polishing. **** Hidden Message ***** Bruce Atwood Astronomy, Room 4055 140 W 18th Ave. Columbus, OH 43210-1173 USA Company: Ohio State University Title: Reserach Scientist Phone: 614 292 6279 Fax: 614 292 2928 E-mail: atwood@ohstpy.mps.ohio-state.edu **** Hidden Message ***** atwood@ohstpy.mps.ohio-state.edu
