Method of cleaning a metallic surface |
摘要 |
There is described a method of cleaning a metallic surface which involves pre-treatment of the surface to reduce the surface to the base metal having a desired surface finish and applying a protective coating to the pre-treated surface. The method of protecting the cleaned surface is also described and comprises applying a synthetic resin coating to the surface of the container, the coating having a base of reactive acrylic polymer. Suitable cleaning methods include directing cleaning fluid at the metallic surface, eg a water and air mix containing abrasive material and etching wire acid. Inhibitors or detergents may be add to the water/air/abrasive mix. The protective coating may be applied to the surface by a spray gun which may utilise electrostatic attraction. Aluminium alloy or stainless steel beer kegs or barrels may be treated in this way. |
