摘要： PURPOSE:To improve the corrosion resistance of a lubrication treated film by treating a steel wire with the solution containing a chelating agent and having the specified PH value in the space between the water cleaning stage and film coating stage of a lubrication treating process. CONSTITUTION:The steel wire coil to be drawn is subjected to a lubrication treatment is the order of a pickling, water cleaning and film coating in advance. The treating stage of the water solution containing the chelating agent of a polyphosphoric acid and its alkali salt or organic acid and its alkali salt, etc. and having 6-12 PH value is added between the water cleaning stage and coating of this lubrication treatment, then, the steel wire coil is subjected to a wire drawing after performing the film coating. The oxidation of the coil in the air can be prevented due to the steel wire coil treatment being performed with the chelating agent containing water solution. Consequently, the corrosion resistance of the lubrication treated film to be formed after its treatment is improved.

摘要： PURPOSE:To carry out uniform etching during the pickling of a metallic material and to facilitate the regulation of the temp. of a pickling soln. as well as to prolong the life of the soln. by treating the material for plastic working with warm or hot water before pickling so as to remove fats and oils, a lubricant and other foreign matter from the surface of the material. CONSTITUTION:When a metallic material for plastic working such as a pipe or a wire rod is pickled with a pickling soln. at 30-70 deg.C, the material is immersed in warm or hot water at a temp. equal to or higher than the temp. of the pickling soln. for a proper time, pulled up and pickled with the pickling soln. such as sulfuric acid. By this method, the pickling soln. is required to be slightly heated with a heating tube, so the corrosion of the heating tube can be prevented.

摘要： PURPOSE:To prevent the formation of white rust and improve the hydrophilic property of surface of aluminum heat exchanger, by forming a chemical film such as an anodic oxidation film and a chromate etc., and an anti-corrosive type surface treatment film such as a high-polymeric resin film and the like over the surface and subsequently applying a suspension liquid including an alumina micro-grain. CONSTITUTION:A chemical film such as an anodic oxidation film and a chromate etc., and an anti-corrosive type surface treatment film such as a high- polymeric resin film and the like are formed over the surface of aluminum heat exchanger. Subsequently, a suspended water solution including an alumina micro- grain is coated over the surface of heat exchanger. While the anti-corrosive surface treatment film formed over the surface serves to produce an anti-corrosive property, the film of alumina micro-grain which is formed by the coat of suspended water solution including an alumina micro-grain acts to provide a durable hydrophilic surface which is less subject to be washed away by water and the like.

摘要： PURPOSE:To ensure decorative coloring and functionality without damaging the matrix of a surface-treated steel-plate by executing the same surface treatment as normal coating pretreatment onto the metallic material, applying a ceramic coating agent having a specific composition and heating and curing the metallic material at a low temperature. CONSTITUTION:The same formation treatment as normal coating pretreatment is executed onto a surface-treated steel plate (hot dipping, electroplating) and an Fe, SUS, Al, Cu, Mg or Ti plate, and a ceramic coating agent is applied and baked. A substance mainly comprising an alkali silicate and ultrafine silica is used as the ceramic coating agent at that time, and 150-300 deg.C are favorable as a baking temperature. Accordingly, ceramic coating having substantially all decorative coloring and functionality (a hard film, hydrophilic properties, fingerprint resistance, heat resistance, corrosion resistance, chemical resistance, weather resistance, release properties, stain resistance, abrasion resistance, insulating properties and workability) except plastics and wood is enabled.
