Baisongmu Fangjunsheng Wood Industry Anti corrosion Wood Market Wood Processing Factory

Description :

　　Junsheng Wood Industry imports Douglas fir wood with square specifications, produced by the manufacturer of Douglas fir wood square for engineering purposes

　　End crack (thread crack): End crack or only limited to threads of Douglas fir, or widened to one or both sides of the top, the latter one is generally referred to as cracking. The key reason is that the water solubility of Douglas fir in the longitudinal direction is longer than that in the rigid direction. When Douglas fir is dry and agitated, water evaporates from the threads much faster than from the sides. The moisture content at the top is lower than that in the middle, and the shrinkage at the top is limited by the middle Douglas fir, resulting in a tensile (flexural) stress field at the top. When the tensile stress exceeds the compressive strength of the Douglas fir, the thread will crack. Manufacturing and installation: Use pre impregnated wood of current specifications and models as much as possible. It is recommended to use hot-dip galvanized nails or screws for connection and installation. Before connection, holes should be opened in advance to avoid cracking. Strong adhesive should be waterproof. Radiation pine rust prevention treatment: 1. Mechanical rust prevention treatment: Tie iron wires around the edges of dried radiation pine, use rust prevention treatment rings, nail plates, etc., and use industrial equipment to force radiation pine without swelling or shrinking, which can also avoid cracking caused by radiation pine.
