Abstract

PURPOSE: A metal panel for a prefabricated water tank and a manufacturing method thereof are provided to ensure high surface adhesion strength on a metal plate by immersing the metal plate in coating phosphate. CONSTITUTION: A metal plate(110) corresponding to the size of a metal panel for a prefabricated water tank is prepared. The surface of the metal plate is washed with water. The metal plate is immersed in the coating phosphate so that a primer layer(120) for enhancing the surface adhesion strength is formed on the metal plate. The metal plate with the primer layer is heated first for 5-10 minutes within a heating furnace maintained at 400-450°C. Adhesive polymer powder is put in an immersion tank and distributed. The first heated metal plate is immersed in a diamond shape in the immersion tank so that the distributed adhesive polymer powder is fused on the primer layer of the metal plate. Adhesive polymer powder is manually sprayed onto the inner surface of the upper rib of the metal plate. The adhesive polymer powder piled-up on the inner surface of the lower rib of the metal plate is blown off with an air gun so that the adhesive polymer powder is uniformly fused on the primer layer of the metal plate. The metal plate is heated secondarily for 5-10 minutes in a heating furnace maintained at 180-220°C. The fused adhesive polymer powder is cooled and dried.
