36 Great Gypsum Ceiling Board Design
What is Gypsum Board?
Gypsum board is the generic name for a family
of panel-type products consisting of a noncombustible core, primarily composed
of gypsum, with a paper surfacing on the face, back, and long edges. Often
called drywall, wallboard, or plasterboard, gypsum board’s noncombustible core
makes it different from plywood, hardboard, and fiberboard. When joints and
fastener heads are covered with a joint treatment system, gypsum board provide
a monolithic surface that is ready for decorative treatment.
Gypsum is a mineral found in sedimentary
rock formations in a crystalline form known as calcium sulfate . One
hundred pounds of gypsum rock contains approximately 21 pounds (or 10 quarts)
of chemically combined water. Gypsum rock is mined or quarried and then
crushed. In a process called calcining, the crushed rock is ground into a fine
powder and heated to about 350 degrees F, driving off three fourths of the
chemically combined water. The calcined gypsum becomes the
base for gypsum plaster, gypsum board and other gypsum products.
To produce gypsum board, the calcined
gypsum is mixed with water and additives to form a slurry that is fed between
continuous layers of paper on a board machine. As the board moves down a line, the calcium sulfate recrystallizes or , reverting to
its original rock state. The paper becomes chemically and mechanically bonded
to the core. The board is cut to length and conveyed through dryers to remove
any free moisture.
Gypsum manufacturers also increasingly
rely on “synthetic” gypsum as an effective alternative to natural gypsum ore.
Synthetic gypsum is a byproduct primarily from the of the flue
gases in fossil-fueled power plants
