Abstract
The present invention provides a mould for shaping a sulphur cement product, which mould has an inner surface describing an inner volume for receiving a cast material, an outer surface and a barrier comprised between the inner surface and the outer surface, which barrier has a thermal conductance per unit area of at most 100 W/m2K in a direction perpendicular to the inner surface. The invention further provides a process for shaping a sulphur cement product.
Claims20
Process for shaping a sulphur cement product comprising cooling a molten sulphur cement product in a mould having an inner surface in contact with the molten sulphur cement product to obtain a shaped solid sulphur cement product, wherein the inner surface is a polymeric material, a silicon-based glass or a combination thereof, and the polymeric material is a silicon-based rubber, polycarbonate, poly(ethylene terephthalate), polyimide, polyamide, fluorpolymer or a combination thereof, and wherein at most 100 W/m2K is diffused per unit area through the mould in a direction perpendicular to the inner surface.
