Effects of salinity on the nail-holding power of dimension lumber used in light-frame wood building

摘要

We studied the effect of salinity on nail-hold-ing power in wood construction. In saline solution, the holding power of nails was less than in purified water. With the increase of salt concentration, the surface and side nail-holding power of the wood specimens both declined, but the differences between salinity treatments were not sig-nificant. However, compared to the surface and side nail-holding power, the power on the edge was generally less and the difference was not obvious in different salt con-centrations. In the same salt concentration, 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.
