Description
The densities of Chinese kiri woods vary from 0.257 (Kawa-gili) to 0.328 (Taiwangili). The moisture contents in green are between 77 and 206% and are a few times more than those of others. The shrinkage ratio is1.862% in volume on an avarege and is very small. The characteristics of the light density and small shrinkage ratio are useful. The silk-like luster of kiri wood surface is valuable as furniture wood. The heat transmission rate in longitudinal direction, 0.26-0.36kJ/m. h. K, is smaller than others. Kiri woods have high viscosity and are good for musical instruments such as a biwa(Chinese mandolin), a shamisen(Chinese guitar), piano and so on. The mechanical properties are not so great on the contrary of the physical properties mentioned above. The high resin contents often cause the color change of the surface. Some protection procedures for it are needed. Kiri woods, useful industrial materials,are used as timbers not only for funiiture and house but also for plywood,particleboard, fiberboard, and laminated wood.
