| 205309000 | Utilizing alkaline bath | 3 |
| 20110108430 | Galvanization system and method of galvanizing treatment using thereof - A galvanization system comprising an alkaline galvanization bath, a positive electrode, and a negative electrode is provided. The alkaline galvanization bath comprises galvanizing solution including about 7 to about 60 g/l of Zn, about 70 to about 200 g/l of alkali hydroxide and about 0.01 to about 5 g/l of additives. The positive electrode is insoluble in the galvanizing solution, having an opposed surface to an object which is supposed to be set in the alkaline galvanization bath and galvanized. The opposed surface of the positive electrode is formed in a rectangular pattern having a side equal to or less than 30 mm or in a circular pattern having a diameter equal to or less than 30 mm. The galvanization system can produce a galvanization membrane of excellent appearance. | 05-12-2011 |
| 20110108431 | Galvanization system and method of galvanizing treatment using thereof - A galvanization system comprising an alkaline galvanization bath, a positive electrode, and a negative electrode is provided. The alkaline galvanization bath comprises galvanizing solution including about 7 to about 60 g/l of Zn, about 70 to about 200 g/l of alkali hydroxide and about 0.01 to about 5 g/l of additives. The positive electrode is insoluble in the galvanizing solution, having an opposed surface to an object which is supposed to be set in the alkaline galvanization bath and galvanized. The opposed surface of the positive electrode is formed in a polygonal pattern having a side equal to or less than 30 mm, which connects arbitrary two apexes of the pattern, in a polygonal pattern having a vertical line equal to or less than 30 mm, drawn between an arbitrary apex and an arbitrary side of the pattern, or in a circular pattern having a diameter equal to or less than 30 mm. The galvanization system can produce a galvanization membrane of excellent appearance. | 05-12-2011 |
| 205310000 | Nitrogen-heterocyclic compound-containing | 1 |
| 20120061250 | Zinc Thin Films Plating Chemistry and Methods - Techniques for electrodepositing zinc (Zn)-containing films are provided. In one aspect, a method of preparing a Zn electroplating solution is provided. The method includes the following steps. The solution is formed from a mixture of at least one zinc salt, a sulfonic acid and a solvent. The sulfonic acid is quenched with a base. A pH of the solution is adjusted to be either less than about 3.5 or greater than about 8.0. The pH of the solution can be adjusted by adding additional sulfonic acid to the solution to adjust the pH of the solution to be less than about 3.5 or by adding a second base to the solution to adjust the pH of the solution to be greater than about 8.0. A Zn electroplating solution and an electroplating method are also provided. | 03-15-2012 |
| 205311000 | Utilizing organic compound-containing bath | 2 |
| 20120138473 | ZINC PLATING BATH ADDITIVE AND ALKALINE NON-CYANIDE ZINC PLATING BATH - Provided is a zinc plating bath additive enabling the rapid formation of a zinc coating having small variations in the thickness depending on the position on the surface of an object to be plated. The zinc plating bath additive contains a water soluble copolymer having, as the structural units, two amine compounds. | 06-07-2012 |
| 205312000 | Nitrogen-heterocyclic compound-containing | 1 |
| 20110210007 | ZINCATE ZINC PLATING BATH - To provide a zincate zinc plating bath capable of efficiently forming a zinc plating film with high brightness and high qualities even at a low current density. The zincate zinc plating bath is used in electroplating for depositing a metal containing at least zinc and forming a zinc plating film. It contains a primary brightener having a function of reducing the size crystals of the metal to be deposited and a plating accelerator containing a heterocyclic compound having a predetermined structure such as 2,5-dimercapto-1,3,4-thiadiazole. | 09-01-2011 |
