Research of the Salinity Effect on 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, the surface and side nail-holding power of the wood specimens would both decline, but the differences between salinity treatments would be 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 performance of holding power of nails showed a downward trend, expect the temporary rise in the middle.
