4. Most conifer wood turpentine to contain turpentine. Turpentine turpentine and rosin in Tongchuan wooden showcase, their presence will affect the coating adhesion of the coating and color uniformity. Baoji wooden showcase, turpentine spill from the timber at a higher temperature, the resulting sticky coating. Clear rosin commonly used method is to use an organic solvent cleaning shenmu wooden showcase, such as alcohol, turpentine, gasoline, toluene and acetone washing, caustic can also be used, such as 5% 6% 4% sodium carbonate solution, or a solution of 5% caustic soda clean, rosin saponification, then brush or sponge dipped in hot water to scrub clean.

When the wood moisture content increased from 0 to 3.2%, ESR intensity increased; the moisture content of 6.3%, the radical concentration reaches a peak, and then when the water content increases, the concentration of free radicals declined. The main reason is that the timber in the presence of excess water molecules and free radical formation of free radicals - water networks and objects, reducing the concentration of free radicals.
