  • Patent number: 7384901
    Abstract: A process for cleaning (e.g., desmutting) an aluminum surface, using compositions free of nitric acid and chromic acid and comprising, in one embodiment, an oxidant and at least one mineral acid salt. In another embodiment, the process uses a composition free of nitric acid and chromic acid and comprising an oxidant, at least one mineral acid salt, and a complexing agent which is a salt of an organic acid. Due at least in part to the absence of nitric and chromic acids, and in particular, strong mineral acids, the cleaning processes of the present invention remove smut residues from aluminum surfaces without significant etching of the aluminum.

    Abstract: A method for chemical etching is disclosed for taking away oxidized film and removing cut as well as punched edge burs of harden-treated carbon steel (SK3, SK4 and SK5). Thereby, the fillet edge of the cut section is achieved. An oxidized film with a thickness of several micrometers is formed when a cut and punched steel is quenched and tempered at high temperature. Due to high strength and hardness of the steel, the oxidized film and edge burs are difficult to be removed by mechanical grinding. Therefore, a suitable electrolyte composes of only a little chemical reagent and oxidizer in deionized water is used to remove the oxidized film and punched bur simultaneously using chemical etching method.

  • Patent number: 6984614
    Abstract: A composition for removing paraffin, wax, or asphaltine deposits from the surface of a crude oil transmission system, such as a downhole tubular, a pipeline, or a surface tank, includes an aqueous sodium hydroxide solution containing from 18% to 25% by weight sodium hydroxide. The composition further includes an acetic acid solution containing from 30% to 55% by weight acetic acid compared to the sodium hydroxide, and a liquid aromatic hydrocarbon having from 6 to 10 carbon atoms and from 15% to 40% by weight compared to the sodium hydroxide. According to the method of the invention, the aqueous sodium hydroxide solution may be metered in a downhole tubular or a pipeline separate from the acetic acid solution, such that heat generated by the mixed composition is generated within the downhole tubular or the pipeline.

  • Patent number: 6916776
    Abstract: A restaurant cleaning towel made from a substrate such as a woven, nonwoven, or knit fabric. A sanitizer release polymer composition comprising at least one cationic (or alternatively, nonionic) surfactant is bound to the surface of the towel. Preferably, the cationic surfactant is present in the sanitizer release polymer composition in an amount of about 1 to about 10 weight percent, based on a total weight of the composition. The composition may also include at least one nonionic co-surfactant in combination with the cationic surfactant. The towel also includes a color label on its surface to identify the area of the restaurant in which the cleaning towel is to be utilized. The towel may optionally include an international icon, a tactile label, and/or a label in a plurality of languages identifying the area where the towel is to be utilized.
