Abstract
A high temperature, abrasion resistant insulating module is described having a sinuously folded, ceramic blanket with a lath covering three side of the folded blanket. The lath has doubled back portions extending into the folds of the blanket on it hot face. To the lathed front face of the folded blanket is applied a layer of thermally stable, abrasive resistant material which not only serves an as abrasion shield to the brittle fibrous material of the blanket, but only serves to stabilize the module and to reduce fiber dust.
Claims10
A method of making a composite insulating block comprising:
- a. anchoring a lath to at least a portion of a hot face of a first insulating block;
- b. anchoring a lath to at least a portion of a hot face of a second insulating block and a portion of a cold face of the second insulating block;
- c. interposing a bonding layer between the first block hot face and the second block cold face;
- and
- d. applying a hard layer to the second block hot face.
2 more elements
A method of forming a lining comprising:
- securing a plurality of composite blocks to a surface to be lined where the blocks comprise a first insulating layer, a first lath associated with a portion of a hot face of the first insulating layer, a second insulating layer, a second lath associated with a portion of a cold face of the second insulating layer, a bonding layer interposed between the first block hot face and the second block cold face.
