HIGH TEMPERATURE CALCIUM SILICATE INSULATION

摘要

A calcium silicate insulation product includes a calcium silicate hydrate matrix that is predominantly but not substantially all xonotlite, for example 51-90 weight percent xonotlite and 10-49 weight percent tobermorite. The insulation product also contains wollastonite, fines of lime and silica, and reinforcing carbon fibers. A method of producing the insulation product includes providing the components of the insulation as dry solids, blending the dry solids with water to form a slurry, filter pressing the slurry to form a pressed shape, and curing the pressed shape under steam pressure only until the desired proportions of xonotlite and tobermorite are achieved in the calcium silicate hydrate matrix.

1. An insulating material, comprising:
xonotlite; tobermorite; wollastonite; carbon fibers; and fines of lime and silica; wherein the xonotlite, tobermorite, wollastonite, carbon fibers, and fines of lime and silica are formed into a substantially uniform rigid body, wherein the insulating material includes a calcium silicate hydrate matrix having 51-90 weight percent xonotlite and 10-49 weight percent tobermorite.
