Do you know these five ways to prevent wood from cracking?

Solutions to wood cracking:

1. Use high temperature qualitative treatment

The method to reduce wood internal cracking can be high temperature qualitative treatment. The residual deformation of the wood surface that produces internal cracking can be eliminated by high temperature and high humidity treatment of the wood before the end of the drying process. During the treatment, the surface of the wood expands due to humidification and produces residual deformation of compression, which offsets the original residual deformation of tension, and the internal cracking of the wood is eliminated.

2. Mechanical method to prevent cracking:

Tie the ends of the dried wood with wire, use anti-crack rings, combined nail boards, etc., and use mechanical methods to force the wood not to expand and shrink, which can also prevent the wood from cracking.

3. Improve the method of sawing when making wood:

Wood is anisotropic. Under the same temperature and humidity changes, its wet expansion and dry shrinkage coefficient is the largest in the tangential direction, followed by the radial direction, and the longitudinal change is the smallest, so producing more quarter-sawn boards when sawing can reduce cracking. In particular, boards with pith are prone to severe splitting when drying, which is caused by the difference in radial and chordal shrinkage near the pith. The best way is to avoid producing boards with pith when making wood.

4. Impregnation treatment with anti-cracking agent:

It is also a better method to use anti-cracking agent for pressure treatment, so that the anti-cracking agent can penetrate deeply into the wood to achieve a good and lasting anti-cracking effect.

5. Wood anti-cracking agent:

Apply wood anti-cracking agent to the ends and surface of the wood to slow down the evaporation intensity of the water on the wood surface, which can reduce the moisture content gradient inside and outside the wood and reduce the cracking of the wood.
