    摘要: An abrasive particle and method are provided for cleaning and rust-proofing steel prior to painting by subjecting the steel to abrasion with abrasive particles coated with a binder such as a synthetic resin which is compatible with the paint to be applied, and a corrosion resistant salt which has a solubility of not more than 20 grams per liter in water at 20.degree. C. The corrosion resistant composition is deposited on the steel surface as it is abraded.

    摘要: The stabilization of pyrophorous iron powder in a liquid medium can be carried out in a very short time and particularly carefully when the powders are contacted with organic compounds which contain nitrogen bound to oxygen, for example, nitromethane, nitrobenzene or nitrosobenzene.
