摘要： The invention relates to a hollow board material comprising a first sheet and a second sheet. A first and a second lath are arranged in parallel between the first sheet and the second sheet along opposite edges of the hollow board material. The first lath and the first sheet are attached to each other by means of a first metal gripping lamina which at least partly covers the first lath. The second lath and the first sheet are attached to each other by means of a second metal gripping lamina which at least partly covers the first lath. Optionally, the first lath and the second sheet are attached to each other by means of a third metal gripping lamina and optionally the second lath and the second sheet are attached to each other by means of a fourth metal gripping lamina. The metal gripping laminas have a first face and a second face which are opposed to each other. Each face comprises a plurality of sharp projections extending substantially perpendicular therefrom and into the laths or the sheets respectively. The metal gripping laminas thereby provides a hollow board material and increases the bending strength of the hollow board material. The invention further relates to a furniture comprising said hollow board material and method for producing said hollow board material.

摘要： Disclosed are a composite gypsum board and a method of preparing gypsum board. The board contains at least one set gypsum layer sandwiched between face and back cover sheets. The set gypsum layer is formed from at least stucco and water. The stucco material generally includes a high salt impurity content, for example, when the stucco is calcined from certain sources of low-quality synthetic gypsum. For example, in some embodiments, the salts are chloride salts, e.g., sodium chloride (NaCl), potassium chloride (KCl), magnesium chloride (MgCl2), and/or calcium chloride (CaCl2). The board and methods improve the bond between the gypsum layer(s) and at least one of the cover sheets (e.g., the back cover sheet). Also provided are methods and systems relating to drying gypsum board.
