Dry standard of Kiln dried wood
Kiln dried wood, refers to the special buildings or metal container artificial drying. Artificial wood drying is artificially controlled the drying medium temperature, humidity and air velocity, the main use of convection heat transfer of gas medium to dry the wood.
Dry kiln drying effect is mainly selected the appropriate benchmark table.Our country’s benchmark two drying time and moisture content.Time benchmark more commonly used for wood drying under 40 mm thickness.Moisture content of the benchmark generally divided into two kinds of temperature rising and fluctuating, the most widely temperature rising type, can be used to dry various tree species and a variety of specifications, especially in 40 mm ~ 90 mm thick wood;Full wave benchmark less drying;Half wave type is mainly used for difficult dry tree species, large cross section of the timber, such as thickness of about 80 mm, 80 mm and 110 mm wood.Our country lumber drying has been listed in the forestry industry standards of the People’s Republic of China (LY/T1068-92).The thickness of the lumber is 15, 25, 30, 40, 50, 60, 70, 80 mm.
