LIGHT WEIGHT LOW DENSITY FIRE RESISTANT GYPSUM PANEL
PROBLEM TO BE SOLVED: To provide a light weight low density gypsum panel containing high expanded vermiculite and having fire resistance performance, which is at least equivalent to marketed fire resistant gypsum panel generally used for building and building use and having high gypsum content, weight and density.SOLUTION: There is provided a method including (A) a process for preparing gypsum slurry having dispersed high expanded particles, (B) a process for arranging the gypsum slurry between a first sheet cover and a second sheet cover to form an assembly, (C) a process for cutting the assembly to a panel having predetermined size and (D) a process for drying the panel, so that a solidified gypsum core has density of about 640 kg/m3 or less per cubic feet and contains crystalline matrix of the solidified gypsum and high expanded particles and the high expanded particles can be expanded with about 300% of the original volume after being heated at about 850°C for about 1 hour.SELECTED DRAWING: Figure 1
【課題】ビル及び建築用途に一般的に使用される市販の耐火石膏パネル石膏パネルは、非常に高い石膏含量、重量および密度を有する。これと少なくとも同等である、高膨張バーミキュライトを含み、耐火性能を有する軽量、低減密度の石膏パネルを提供する。【解決手段】固まった石膏コアが、立方フィート当たり約６４０ｋｇ／ｍ３以下の密度を有し、固まった石膏の結晶母体及び高膨張粒子を含み、前記高膨張粒子が、約８５０℃で約１時間加熱された後、元の体積の約３００％に膨らませることができるように、（Ａ）分散された高膨張粒子を有する石膏スラリーを調製する工程（Ｂ）第１のシートカバーと第２のシートカバーとの間に前記石膏スラリーを配置して、アッセンブリーを形成する工程。（Ｃ）前記アッセンブリーを、所定の寸法のパネルに切断する工程（Ｄ）前記パネルを乾燥させる工程；を含む方法。【選択図】図１
