  • Publication number: 20190330120
    Abstract: A joint compound system includes a set-inhibited, pre-wetted, setting-type, ready-mix joint compound and a set initiator. The set-inhibited, pre-wetted, setting-type joint compound includes a ready-mixed, setting-type joint compound base with a calcium-free phosphate set preventing agent that impedes chemical hydration of a gypsum component of the setting-type joint compound. The joint compound base is free of calcium carbonate. The set initiator includes alum to reinitiate the chemical hydration reactions.

  • Publication number: 20170241881
    Abstract: Embodiments of a system and a method for evaluating a joint compound specimen can be used to determine a numerical sandability value for the specimen. A moving assembly is configured to move a sanding member in a sanding direction relative to the joint compound specimen supported in a support fixture. An actuator assembly is configured to drive the sanding member into contacting relationship with the joint compound specimen such that the sanding member exerts a controlled amount of pressure against the joint compound specimen. The force gauge is configured to measure a resistance force against the sanding member in a resistance direction in opposing relationship to the sanding direction. A processor programmed with a joint compound analyzing application is configured to use a force signal from the force gauge that is indicative of the resistance force to determine the sandability value for the joint compound specimen.

  • Patent number: 8642346
    Abstract: At least one of these or other problems is reduced using a building material that is uniquely identifiable. A method of making an identifiable gypsum-based building product includes selecting a tagging material occurring naturally in a component of the building material and choosing a carrier substance having a high concentration of the tagging material. By selecting an amount of the carrier substance and adding it to the building material, a building product having a unique product characteristic is created. In a second embodiment of the invention, a second tagging material is combined with the first tagging material to create a unique product. In yet another embodiment of the invention, a supplemental amount of the tagging material is added to the gypsum-based composition in addition to the carrier substance. Some tagging materials are useful in a gypsum-based composition to produce a visual confirmation of the presence of the tagging material.

  • Patent number: 8057915
    Abstract: The acoustical product of the present invention comprises an acoustical product including a matrix of calcium sulfate dihydrate crystals and expanded perlite distributed throughout the matrix. The expanded perlite has a particle size distribution with at least 10% of the perlite having a particle diameter of 700 microns or more, and the amount of expanded perlite to calcium sulfate dihydrate is about 35% to about 75% by weight, based upon the dry weight of the calcium sulfate dihydrate. A dispersing agent and glass fibers having a particle length of about ΒΌ inch to about 1 inch are dispersed throughout the gypsum matrix.
