Internal wood cracking occurs inside the wood, cracking along the wood rays, such as honeycomb, also called honeycomb cracking. There are no cracks on the surface, only sawing can be found. But it is usually accompanied by uneven appearance or significant shrinkage, or charring, or lighter weight. This is characteristic of over-drying.

Surface cracks are longitudinal cracks that occur along the wood rays on the outer surface of sawn timber (usually the outer cut surface of a chord-cut board). It is caused by excessive surface tensile stress in the early stage of drying

"Natural is the best." In modern society, this has almost become a consensus of people. Everyone knows the reason: modern technology is used in various fields, and almost all products are linked to technology, so that natural things are becoming more and more scarce, and people are beginning to miss the "natural gas" that can be seen everywhere. good time.

Wood modification is the process of improving the properties of wood. It uses chemical, biological or physical media to act on the wood to enhance the desired properties of the wood during the service cycle. In addition, the modified wood itself should be non-toxic during the service cycle and not release any toxic substances during or after the service cycle.

How to prevent and control the blue of wood? Is there a good way?

The discoloration of wood, simply put, is the color change on its surface due to the action of the environment (sunlight, oxygen, moisture, temperature) and microorganisms (fungi).

The discoloration of wood, simply put, is the color change on its surface due to the action of the environment (sunlight, oxygen, moisture, temperature) and microorganisms (fungi). Discoloration can occur on logs, sawn timber, and wood products.

1. Density reduction Mainly from the partial loss of hemicellulose. Most studies show that 5-8% of hemicellulose is degraded with little sacrifice in structural strength.

Factors Affecting Wood Drying Speed The main factors affecting the drying speed of wood are medium temperature, humidity, air circulation speed, wood moisture content gradient, and temperature gradient.
