Abstract

PURPOSE: To make on the inside surface of a cast iron pipe an anticorrosion coating film free of pinholes, by mixing a resin composite powder prepared by a melt blending method with 4W40wt% inorganic powder by a dry blending method, and applying the powdery paint onto the inside surface.
CONSTITUTION: A resin powder (e.g. a low-density polyethylene resin powder containing 2wt% carbon black) which was prepared by a melt blending method, is mixed with 5W40wt% inorganic powder (silica powder) by a dry blending method. The obtained powdery paint is applied in a thickness 400μ or so onto the inside surface of a cast iron pipe (e.g. a ductile cast iron pipe preheated at 270°C), by an air spray coating method or the like. The fused and generated coating film is free from defects such as bubbles or pinholes, and also excellent in anticorrosion ability.
