摘要:
The present invention relates to compositions, kits and processes for the brightening of metal surfaces by the application of the chemical compositions. These compositions act to release hydrofluoric acid as a brightening agent. The solutions are preferably mixed during application of the brightening composition to a metal surface by mixing the solutions immediately prior to or even during application of the solution. This can be readily accomplished by mixing two solutions, one having a fluoride source and the other having a strong acid to release hydrofluoric acid from the fluoride source, the mixing occurring immediately before spray application, during spraying, or immediately after spraying of the two solutions. Mixing may be done on-site, which means that mixing is performed at the site of use, usually on the same day of use or even within a few (less than 10) minutes of use. Optional, longer term mixing may be performed, even over night or over the weekend, but actual solutions of hydrofluoric acid do not have to be shipped to the site.

The present invention relates to a two-part antimicrobial composition comprising at least one chlorine dioxide generating component comprising at least one metal chlorite and at least one acid-forming compound in a solid carrier, and at least one liquid aqueous component. The composition further comprises at least one antimicrobial fatty acid having from about 2 to about 15 carbon atoms, and preferably from about 6 to about 12 carbon atoms. The components, upon mixing, form a composition having a pH in the range of about 5 to about 10.

A method of treating a surface of a metal is provided. A source of fluoride ion is mixed with a source of acid to form hydrofluoric acid and, when applied to a metal surface to be treated, the hydrofluoric acid acts as a brightening agent.

A method of lubricating conveyors with a lubricating concentrate formulated to contain about 0.5 wt-% to 90 wt-% of a fatty amide ethoxylate phosphate ester diluted to a use solution formulated to contain about 5 ppm to 1000 ppm of a fatty amide ethoxylate phosphate ester is described. The use solution is applied to an intended surface for lubrication. The lubricant can contain a variety of other chemical agents to provide additional desired properties including surfactants, chelating agents, sanitizing agents, and others. The lubricant concentrate or use solution is especially useful on conveyor systems with moving beverage containers such as glass, metal or plastic containers.

Disclosed is a process for the pretreatment of a plant fluid effluent containing odor compounds including an alkyl mercaptan or an alkyl thiol, an amine compound, ammonia, hydrogen sulfide and mixtures thereof by contacting the plant effluent with an atomized aqueous solution comprising a peroxy acid compound. When contacted with the peroxy acid, odor compounds in the effluent are oxidized and converted from the gaseous phase into a chemically modified highly aqueous soluble phase in the aqueous treatment. The use of such a process produces a significant improvement in odor quality index as measured by a conventional process using an expert panel when compared to conventional treatment methods.
摘要:
The present invention relates to a method and to a device for sensing low levels of iodine in an aqueous solution by using an extraction procedure whereby iodine from the aqueous solution is extracted into a substantially water-insoluble organic phase, and testing measuring the concentration of iodine in the organic phase using optical absorption techniques. The measured concentration of iodine can then be equated with concentration of iodine or iodine in the aqueous solution.
摘要:
A system for measuring and controlling the concentration of a chemical agent in a solution has a reaction cell for receiving a sample, a titrant dropper for releasing one or more drops of titrant into the sample, a first photosensor for sensing disruptions of light for every drop of titrant released, and a controller that communicates with the photosensor and computes the concentration of the chemical agent based on the number of disruptions of light at the photosensor. The present invention also includes a method for sensing and controlling the concentration of a chemical agent in a solution. The method includes having a sample containing the chemical agent, triggering the release of a number of drops of titrant into the sample, detecting the number of drops released into the sample, and computing the concentration of the chemical agent in the sample based on the number of drops of titrant released into the sample.
