Common defects in wood section hydrothermal treatment and solutions

(1) Radial cracking and annular cracking at the end of the wood section.

Cause: The heating rate (heating rate) is too fast, or the cooling rate is too fast.

Method: Reduce the heating or cooling rate.

(2), the plasticity of the wood segment is insufficient

Cause: The heating temperature is not high enough, or the hydrothermal treatment time is too short

Method: increase the heating temperature and prolong the hydrothermal treatment time

(3), the plasticity of the wood section is too large

Cause: The temperature is too high and the hydrothermal treatment time is too long

Method: Reduce heating temperature and shorten hydrothermal treatment time
