摘要： PURPOSE:To prevent sulfur staining and the offensive odor of hydrogen sulfide getting trouble in the canning of food containing protein containing sulfur such as fishes, meats, beer or the like without changing the properties of content and contamination by a heavy metal. CONSTITUTION:A volatile sulfide and a substance forming a stable sulfide with sulfide ions are mixed into a coating layer between the metallic material of a metal-resin laminate, in which the coating layer having permeability to the volatile sulfide and water is laminated on the surface of the metallic material, and the coating layer. According to the method, a sulfide in canned food is taken into a can vessel, thus preventing the generation of sulfur staining and an offensive odor. Metallic salt, monosaccharide, fumaric acid salt, furfural, D-glucuronolactone and potassium bromate are cited as a substance forming the stable sulfide.

摘要： PURPOSE:To obtain an Si-contg. steel plate of superior phosphatability by coating an S compd. on the surface of said steel plate then annealing the same in a non-oxidative atmosphere thereby suppressing the deposition of C on the surface by the effect of Si. CONSTITUTION:An S compd. of thiourea or the like is coated in the form of an aq. soln. on the surface of a steel plate contg. >=0.2% Si, after which the steel plate is subjected to prescribed annealing in an non-oxidative atmosphere. Since the amt. of C on the surface of the high Si steel plate is reduced by the coating of the S compd., the surface deposition of C by the effect of Si during annealing is suppressed and the high Si steel plate of considerably improved reactivity with phosphoric acid is obtained.

摘要： PURPOSE:To activate the surface of acid-waste or polished surface of a steel plate for raising its treatability with a phosphate before painting by irradiation of laser light to the steel surface or thinly galvanized surface of an one-side hot galvanized steel plate. CONSTITUTION:In applying hot galvanization to only one side of a steel plate with molten zinc, etc., the nonhot galvanized surface or thinly galvanized surface of the steel plate is pretreated by acid washing or mechanical polishing and therefore, its treatability with phosphate before painting is lowered. Thus, a pulse laser light is irradiated onto the acid-washed or polished surface for activation and also for vaporizing a small amount of residual zinc, thereby enabling the subsequent surface treatment of the steel plate with phosphate to be performed effectively. Thus, the subsequent electrodeposition coating on the steel plate so treated can be completely carried out.

摘要： PURPOSE:To obtain a hot dip galvanized steel sheet hardly causing peeling of plated extreme surface layer and excellent in adhesive strength, by controlling respective atomic concentrations of Al and Pb as plated extreme surface layer components and simultaneously specifying so that they satisfy a specific inequality. CONSTITUTION:In a hot dip galvanized steel sheet, the atomic concentrations of Al and Pb as components in an extreme surface layer within 100Angstrom from the surface are limited to =2,250psi, a point representing a passing-level adhesive strength of >=2,000psi, and a point representing an adhesive strength of =2,000psi.

摘要： PURPOSE:To produce a tin plate having excellent corrosion resistance by treating a cold rolled steel sheet as a cathode in both of electrolytic degreasing and electrolytic pickling stages prior to plating in the stage of electroplating Sn to the steel sheet and further alloying Sn and Fe thereby producing the electroplated tin plate. CONSTITUTION:Sn is electroplated onto the surface of the cold steel sheet and further the Sn plating layer is heated to alloy the plating layer with the Fe of the steel sheet to produce the tin plate having the excellent corrosion resistance. The steel sheet is subjected to the electrolytic degreasing by an aq. alkaline soln. and the electrolytic pickling by an acid soln. as the pretreatment for the electroplating to clean and activate the surface of the steel sheet. The steel sheet as the cathode is energized between the same and the anode which is a counter electrode in both of the electrolytic degreasing and electrolytic pickling stages. The steel sheet acts of courses as the cathode in the case of the Sn electroplating treatment. The thin plate having the better corrosion resistance than in the case of partly using an anodic treatment in combination is obtd. by using the steel sheet as the cathode in the entire pass of the Sn electroplating.

摘要： PURPOSE: To provide a cathode deposition type water-soluble or water-dispersible electrodepositing paint having excellent adhesion suitable for use in priming automobile, etc., by selecting paint having characteristic values within a specified range, said value being obtd. by constant-current electrolysis.
CONSTITUTION: A cationic water-soluble or water-dispersible electrodepositing paint is prepd. by using, as a base, a resin obtd. either by reacting the epoxy groups of an epoxy resin with a polyamine to form a cations, or by reacting the hydroxyl groups in a resin with an amino group-contg. isocyanate to modify the resin to a cation. An electrodepositing paint is selected therefrom, which has a value within the range of 5,6W1, said value being the product of a characteristic value of the paint obtd. from constant-current electaolysis, that is, electrolytic current density Io (mA/cm
2 ) by the square root of critical timer τ(sec) at which paint deposition begins. The selected paint is applied as a primer to a glavanized sheet, etc.
