Defectos por secado
Ease of Drying: Drying is reported to be easy and fast. Air drying of 4 cm thick boards takes about 70 days. Drying Defects: Risk of surface checking, cupping, warping and end splitting is reported. Kiln-dried boards are usually free from serious defects, but cupping may occur. Kiln Schedules: Schedule recommended for Ramin. For stock over 1-1/2 inches the UK schedule B is recommended. In Malaysia kiln-drying schedule C is advised, but kiln schedule B for boards thicker than 4 cm. Kiln drying of 2.5 cm thick boards to12% moisture content takes
