    摘要: A method of controlling the ratio of hydration time (HT) to open time (OT) in the manufacture of composite materials from a mixture containing hydratable calcium sulphate such as gypsum binders, aggregates, fibers, water additives and other additives is disclosed. The method includes adding a retarder-accelerator combination such as Retardan and potassium sulphate to the mixture and applying pressure. The retarder-accelerator combination and application of pressure provide advantageous reduction in the ratio HT:OT. More particularly, HT:OT can be reduced to less than 1.

    摘要: A flat extrusion method for manufacturing especially multilayer panels and device for working the method. The method consists of the following method steps: simultaneous addition of mixtures by mixing and spreading devices (1) into a perpendicular conically tapered shaft (A, B) formed by circulating compression belts (13, 14); compression of the mixture by the conical design of shaft (B), followed by traversing a section (C) in which the compression belts are arranged parallel to one another and at a distance which corresponds to the thickness of the finished panel strand; curing of the mixture in the downstream calibrating section (3).

    摘要: The present invention is directed to improvements in apparatus and proces for the continuous production of inorganically bonded materials, the apparatus and process providing a pressureless transition zone without the action of pressure on a continuous sheet of material arranged between a high-pressure compression unit and the calibrating unit, and where the calibrating unit is immediately preceded by a recompression unit, which applies an active pressure on the continuous sheet of material after it passes through the pressureless zone and before it enters the calibrating unit and where this active pressure is sufficiently high that the nominal thickness of the continuous sheet of material is equal to or less than the finished continuous sheet of material and nominal density of the continuous sheet of material are equal to or greater than the density of the finished continuous sheet of material.
