The invention mainly relates to the technical field of wood products
processing, and discloses a
processing method for improving the durability of birch. The
processing method includes the steps of
cutting, soaking, freezing, strengthening and
drying; the method is simple, the strength and rigidity of the birch after being processed are improved obviously, the use range of the birch is increased,and the
economic income is increased by 18.6%; birch sections are peeled and then
cut, and later even processing is facilitated; the processing efficiency is improved; wood beams are placed in a
preservative liquid for being soaked at high temperature, the
preservative liquid is promoted to be infiltrated into the wood beams, residual
bacteria and worm eggs in the wood beams are killed,
mildew andmoth are avoided, and the anti-
corrosion performance of the wood beams is improved; the
preservative liquid is extracted from pure
Chinese herbs and without any poisonous
reagent, and the fact that
human health is harmed in the processing and using process of the birch is avoided; after being soaked, freezing is conducted through gradually reducing the temperature, water is changed into crystalline water, the
porosity between
fiber of the birch is increased, the flexibility of the birch is improved, then low-temperature
drying is conducted, absorption of the wood beams to a processing liquidis facilitated.
