DISSOLVING ZINC GRAIN AND ITS PRODUCTION

PURPOSE:To produce the zinc grain highly soluble in sulfuric acid, etc. CONSTITUTION:Molten zinc is dripped into a cooling medium from a nozzle to produce a zinc grain. In this case, the cooling medium is controlled to 10-90 deg.C, the molten zinc is dripped so that the molten zinc droplet immediate...

Zusammenfassung:	PURPOSE:To produce the zinc grain highly soluble in sulfuric acid, etc. CONSTITUTION:Molten zinc is dripped into a cooling medium from a nozzle to produce a zinc grain. In this case, the cooling medium is controlled to 10-90 deg.C, the molten zinc is dripped so that the molten zinc droplet immediately before dripping is brought into slight contact with the cooling medium, and the zinc grain with >=10% of its surface area formed with a fine crystal face is produced. The solubility is remarkably enhanced as compared with the conventional zinc grain, and a galvanizing bath, etc., are obtained in a shorter period than before.
