DEPARTMENT OF THE NAVY WASHINGTON DC
Pagination or Media Count:
The present invention relates to stripping agents for removing epoxy coatings and similar chemically resistant coatings from steel surfaces. The invention is particularly intended for spraying at elevated temperatures of around 180 degrees F and is suitable for recycling of the stripping solution. This invention is also particularly intended for use with bilge and tank cleaning systems, such as disclosed in U.S. Patent No. 4,530,131, issued 23 July 1985, for an Automatic Vacuum Recyclable System for Chemical-Thermo Cleaning of Ship Tanks and Bilges, and is commonly assigned. The system in the patent sprays and recirculates hot solutions for cleaning, stripping, derusting, and passivating tanks and bilges. Typically 500 gallons of solution are sprayed within tanks at 50 gpm, at 100 psi, and at 180 degrees F through a set of nozzles. The solutions can also be sprayed by a hand lance at 2000 psi, for example.
