Aluminum Rigid Container Sheet Cleaner And Cleaning Method

US Patent:
5622569, Apr 22, 1997
Filed:
Jun 2, 1995
Appl. No.:
8/459926
Inventors:
Alfred M. Dennis - Newburgh IN
Joseph D. Guthrie - Murrysville PA
George T. Gregory - Lower Burrell PA
Assignee:
Aluminum Company of America - Pittsburgh PA
International Classification:
C23G 100, B08B 100, C09K 1302
US Classification:
134 2
Abstract:
A method for cleaning and modifying the surface of aluminum container sheet to make improved food can bodies and/or beverage can ends therefrom. The lowering of magnesium levels on an aluminum oxide surface and through the oxide-metal interface of this sheet, and deposition of at least some phosphorus-containing complex thereon produces container sheet that exhibits improved corrosion performance. The method comprises contacting said container sheet for less than about 20 seconds with a cleaner which preferably includes: about 1. 0-10. 0 wt. % (10. 0-100. 0 g/L) of sodium carbonate; about 0. 1-2. 5 wt. % (1. 0-25. 0 g/L) of sodium hydroxide, said cleaner including a total carbonate and hydroxide concentration in excess of about 3. 0 wt. % (30. 0 g/L); about 0. 1-2. 5 wt. % (1. 0-25. 0 g/L) of sodium gluconate; about 0. 1-2. 0 wt. % (1. 0-20.

Aluminum-Magnesium Alloy Sheet Product And Method For Inhibiting Formation Of A Film Thereon

US Patent:
4778533, Oct 18, 1988
Filed:
Feb 4, 1987
Appl. No.:
7/010626
Inventors:
George T. Gregory - Lower Burrell PA
Donald L. Nock - New Kensington PA
Assignee:
Aluminum Company of America - Pittsburgh PA
International Classification:
C23G 100, C23F 100
US Classification:
134 29
Abstract:
An aluminum-magnesium alloy sheet product having improved levels of brightness for use as container stock including food containers and beverage container ends, said sheet product chemically treated with an alkaline-based cleaner containing a sufficient amount of a compound of 1-hydroxyethylidene-1, 1-diphosphonic acid (HEDP) to inhibit the formation of a magnesium oxide-containing film thereon. Preferably, the sheet product is cast from a 5000 Series aluminum alloy (Aluminum Association designation) and the cleaner contains between about 0. 2-0. 7% by weight of the HEDP compound. A method for improving the brightness levels of an aluminum-magnesium alloy sheet product is further disclosed. The method comprises chemically treating the sheet product with an alkaline-based cleaner containing between about 0. 2-0. 7% by weight of an HEDP compound to inhibit the formation of a magnesium oxide-containing film thereon.
