  • Patent number: 10550481
    Abstract: The current invention relates to a micro-encapsulated, volatile vapor corrosion inhibitor (VCI), and method for the use of same. More particularly, it relates to a fluid composition, and microencapsulation of the fluid composition, that inhibits corrosion and tarnishing and that may be relatively non-toxic. The VCI is intended to be employed in varying concentrations depending on the intended application and deployed via microcapsules. The microcapsules may be adapted to release the VCI over time, or all at once. To effect this, the microcapsules may be adapted to be breached at varying times or at the same time. By adapting the microcapsules, or the method of breaching the microcapsules, the rate at which the VCI is released may be controlled.

  • Patent number: 10450467
    Abstract: The present disclosure describes a strategy to create self-healing, slippery liquid-infused porous surfaces. Roughened (e.g., porous) surfaces can be utilized to lock in place a lubricating fluid, referred to herein as Liquid B to repel a wide range of materials, referred to herein as Object A (Solid A or Liquid A). Slippery liquid-infused porous surfaces outperforms other conventional surfaces in its capability to repel various simple and complex liquids (water, hydrocarbons, crude oil and blood), maintain low-contact-angle hysteresis (<2.5°), quickly restore liquid-repellency after physical damage (within 0.1-1 s), resist ice, microorganisms and insects adhesion, and function at high pressures (up to at least 690 atm). Some exemplary application where slippery liquid-infused porous surfaces will be useful include energy-efficient fluid handling and transportation, optical sensing, medicine, and as self-cleaning, and anti-fouling materials operating in extreme environments.

    Abstract: A water treatment agent for removing pollutant by reinforcing potassium permanganate with intermediate manganese consists of a potassium permanganate and a chelating agent, or, alternatively, consists of a potassium permanganate, a chelating agent and an inducer. The chelating agent is capable of forming a coordination complex with the intermediate manganese which is produced during the reaction of potassium permanganate and organic substance. Thus self decomposition of intermediate manganese is reduced so that the effective utilization rate is increased and the capability for potassium permanganate to degrade organic pollutants is enhanced. The inducer accelerates the production of the intermediate manganese and increases the utilization rate so that the capability of potassium permanganate for degrading the organic pollutants is further enhanced.

  • Publication number: 20140251921
    Abstract: The invention provides methods and compositions for a composition and/or a method for treating impurities in a circulating water system. The circulating water system impurities may be oversprayed paint in paint spray booth applications. The composition includes an aqueous solution of a cationized starch, a polybasic aluminum salt such as aluminum. chlorohydrate or polyaluminum chloride and a solution of a medium to high MW aqueous flocculant. The composition is particularly useful when added to recirculating scrubber water in paint spray booths for effectively treating both water based and solvent based paints.

  • Publication number: 20140251920
    Abstract: The present invention provides improved methods for purifying and/or removing multiply charged cations and suspended solids from water. In particular the process relates to an additive composition that has the appropriate surfactant characteristics for effectively removing multiply charged cations and suspended solids from an aqueous or oil/aqueous mixed phase via foam fractionation. According to the invention, a hydrophobically modified polymer that acts as an associative thickener is used in the presence of a source of alkalinity or anionic reactant as well as surfactant in appropriate ratios to facilitate multiply charged cation and suspended solids removal for water purification in any of a number of commercial, environmental and industrial applications.
