The Reduction of Tank Treatment Costs: A description of a method of using a plastic ball blanket on open treatment tanks to reduce the cost of surface preparation for protective painting

IN aircraft engineering as in other industries it is often necessary to make use of open process tanks. Such tanks are generally at elevated temperatures and are both inefficient and unpleasant to work with. Not only arc they a major source of heat and evaporation losses, but they frequently produce corrosive or noxious vapours which rapidly attack any neighbouring surfaces and may be a hazard to health.
