Abstract
A method for the production of insulation plates from an aqueous pulp comprised of mineral fillers, cellulose-containing products and a binding agent based on a novolak wherein a pulp is used comprising an additive substance selected from the group consisting of fatty acid amides or substituted fatty acid amides, the plates obtained after curing are used, inter alia, as mold covering plates or as so-called tundish plates for application in continuous casting processes.
Claims16
A resin mixture formed by pulverizing a solidified melt of a novolak and at least one additive selected from the group consisting of fatty acid amides and substituted fatty acid amides.
A process for the production of insulation plates comprising forming an aqueous pulp comprised of cellulose containing products, mineral fillers and a novolak binding agent, probing the aqueous pump onto a fine-mesh screen, extracting the water from the pulp under vacuum to obtain a “green” filter cake plate and curing the plate at a temperature of at least 120° C., the improvement comprising adding to the pulp at least one additive selected from the group consisting of fatty acid amides and substituted fatty acid amides.
