Abstract
A composite insulating material is provided. In one or more configurations the composite insulating material includes one or more active or responsive elements that mitigate corrosion under insulation (CUI). In a further aspect of the present invention, one or more active components of a composite insulation material are provided that dynamically generate an insoluble barrier within an insulating material through a bio-mineralization process.
Claims6
A composite insulation material, comprising:
- an anti-corrosion layer comprising a hosting matrix formed of an insulating material comprising at least one of mineral wool insulation, glass wool, fiberglass, and polyurethane foam, wherein the hosting matrix includes a plurality of porous superabsorbent polymers distributed within the hosting matrix, wherein the porous superabsorbent polymers are host to a plurality of microorganisms, wherein the microorganisms are adapted to precipitate an insoluble material through a biomineralization process in the presence of at least liquid water, oxygen and a nutrition source;
- and
- an insulating layer.
