    摘要： The present invention relates generally to a method of producing a fire-resistant gypsum board comprising a gypsum core, the method comprising providing a calcium sulfate slurry comprising a silicone oil having a hydride content of no more than 0.01 equivalents of Si-H per equivalent of silicon in an amount of 0.1 to 1 wt% of the mass of the gypsum core; allowing the calcium sulfate slurry to set; and drying the set gypsum material to provide the gypsum core. The invention also relates to a fire-resistant gypsum board comprising a gypsum core that shrinks by less than 6% by volume when heated to 850 °C, wherein the gypsum core comprises a silicone oil having a hydride content of no more than 0.01 equivalents of Si-H per equivalent of silicon, present in an amount in the range of 0.1 to 1 wt% based on the mass of the gypsum core.

    摘要： A system for visually enhancing a surface. For example, the system may include an assembly that may be configured to project a laser line across at least a portion of the surface. Versions of the laser line may be projected at an angle of incidence relative to a plane defined by the surface. For example, the angle of incidence may be in a range of about 5 degrees to about 60 degrees. In one version, the laser line may be substantially perpendicular to a central axis of the surface. In addition, the laser line may enable enhanced, qualitative user visualization of the surface and non-planar distortion in the surface.

    摘要： Disclosed is a building board construction that provides enhanced acoustical properties. In one possible embodiment, the board is a gypsum board with opposing facing sheets and an intermediate set gypsum core. An opened celled polymeric sheet is formed within the gypsum core and gives the resulting board enhanced sound absorption. In an alternative embodiment, individual pieces of polymeric foam are used in stead of the polymeric sheet. Also disclosed are various manufacturing methods whereby boards with enhanced acoustical properties can be formed in an continuous process. The various components of the present disclosure, and the manner in which they interrelate, are described in greater detail hereinafter.
