Abstract: The disclosure provides for a method for preparing a vacuum insulated panel. The method comprises forming an internal cavity between a liner and a wrapper and preparing filler material to be disposed in the internal cavity. The filler material comprises a first part and a second part. Preparing the filler material comprises treating a surface of the first part, wherein the treating prepares the surface to receive a coating comprising a first charge. The preparing further comprises coating the surface of the first part with a chemical comprising a first charge. The coating forms a first surface charge on the surface of the first part. The method further comprises mixing the first part with the second part forming the filler material. The second part comprises a material having a second surface charge opposite the first surface charge.

Abstract: A vacuum insulated appliance includes a cabinet defining at least one compartment. The cabinet includes a wrapper and a liner assembly. The wrapper and the liner assembly define an insulation cavity therebetween. The insulation cavity is under an at least partial vacuum. A trim breaker assembly is coupled to the wrapper and the liner assembly. The trim breaker assembly defines a wrapper groove to receive an edge of the wrapper and at least one liner groove to receive at least one edge of the liner assembly. An adhesive is disposed in the wrapper groove and the at least one liner groove, with the adhesive sealing the insulation cavity. The adhesive includes a platy additive to reduce gas permeation therethrough to maintain the at least partial vacuum in the insulation cavity.

Abstract: A method of forming an insulation material for a vacuum insulated structure includes heating glass flakes to at least a glass transition temperature of the glass flakes to induce a phase separation of the glass into an acid insoluble silica phase and an acid soluble phase. The glass flakes can be derived from a glass composition containing (by weight): SiO2 from about 40% to about 80%, B2O3 from about 10% to about 40%, Na2O from about 1% to about 10%, Li2O from about 0% to about 3%, CaO from about 0% to about 10%, ZnO from about 0% to about 5%, P2O5 from about 0% to about 10%, and Al2O3 from about 0% to about 10%. The method also includes a step of etching the glass flakes to dissolve the acid soluble phase to form porous glass flakes.

Abstract: A method and system for forming an insulation package for use in a vacuum insulated structure is provided. A slurry containing a liquid and an insulation material is formed. The slurry can be supplied to an envelope under vacuum, wherein the envelope is gas-permeable and permeable to the liquid. At least a portion of the liquid is drawn through the envelope and at least a portion of the insulation material is retained within the envelope to form an insulation package. One or more insulation packages can be disposed within an insulating cavity and the insulating cavity can be evacuated to decrease a pressure therein to form a vacuum insulated structure.
