The Effect of Salinity on the NailHolding Power of Dimension Lumber

This article mainly studied the effect of salinity on the nailholding power in wood construction. The results showed that: in saline solution, the holding power of nails was smaller than that in purified water condition. With the increase of salt concentration, both of the surface and side nailholding power of the wood specimens was decline, but the differences between salinity treatments were not significant. However, compared to the surface and side nailholding power, the power on the edge was generally smaller and the difference was not obvious in the treatment of different salt concentrations. In the same concentration of salt environment, with the extension of the processing cycle, the holding power of nails showed an increasing first and then downward trend.
