equilibrium moisture content การใช้

• These relative humidities correspond to equilibrium moisture contents of wood of 19 and 15 percent, respectively.
• Standing dead trees may be cut one month or several decades after they died, so the term " dead standing " does not necessarily mean the logs have dried down to equilibrium moisture content.
• For wood that is to be used in making furniture, for wood floors, in construction or for any building project, the ideal state is one of equilibrium moisture content ( EMC ).
• Within about four years, green logs which are part of a completed log house reach equilibrium with local conditions and have an equilibrium moisture content ( EMC ) of between 6 % and 12 %.
• The "'equilibrium moisture content "'( "'EMC "') is the moisture content at which the wood is neither gaining nor losing moisture; this however, is a dynamic equilibrium and changes with relative humidity and temperature.
• Since logs reach equilibrium moisture content at about 6 % and 12 % ( in North America ); since most kiln-dried logs are dried down to about 18 % to 20 % moisture content kiln-dried logs can be expected to shrink and settle over time, but to a lesser extent than green logs.
