PROCESS AND DEVICE FOR PRODUCING MULTI-LAYERED, FIBRE-REINFORCED PLASTER PLATES |
摘要 |
<p>Fibre-reinforced plaster plates are produced in a multi-layered continuous filtration process. A suspension of plaster and wet processed fibres, preferably from used paper, is dewatered on at least two travelling screens. At least two layers are produced in essentially identical filtering units that work in opposite directions. The layers are then reversed so that their top surfaces face each other. When three layers are processed, the central layer may be composed of a dispersible, binder-containing material. Several devices and process configurations are disclosed.</p> |
