    Lime is typically used on large coal- or oil-fired boilers as found in power plants, as it is very much less expensive than caustic soda. The problem is that it results in a slurry being circulated through the scrubber instead of a solution. This makes it harder on the equipment. A spray tower is typically used for this application. The use of lime results in a slurry of calcium sulfite (CaSOОнлайн-запрос

  • Gypsum an overview | ScienceDirect Topics

    When gypsum board is exposed to heat or fire, the water is vaporized, retarding heat transfer. Gypsum also equilibrates humidity and heat peaks. Gypsum board is capable of storing humidity when a room is humid and automatically releasing humidity if the indoor air is too dry. It acts as a thermal insulator because of its low thermal conductivity. Furthermore, it also has ‘heat-storing’ abilities. SmallОнлайн-запрос
