Title:
石膏ファイバボードパネルの製造方法及び水噴霧装置
Document Type and Number:
Japanese Patent JP4683693
Kind Code:
B2
Abstract:
An improved method and apparatus for imparting a smooth surface to gypsum fiber panels. The method involves imparting energy to the surface of a slurry as the slurry is dewatered just prior to rehydration. The apparatus used to impart the energy is a fluid spray including a source of pressurized fluid such as a pump or blower, a distribution manifold and a plurality of nozzles to direct the fluid spray at the surface of the slurry. In operation, the fluid spray is directed against the surface of the slurry. The flow disrupts the slurry to a fraction of its total depth, thus dispersing clumps or flocs of commingled crystals and fibers in the depth that would give the surface of the finished panel a rough surface if they were allowed to remain.
