Wood moisture test

1. What is the moisture content of wood?

Under normal conditions, wood and its products will have a certain amount of moisture. In China, the percentage of the weight of the moisture content in the wood and the weight of the dried wood is defined as the wood moisture content.

The moisture content can be calculated based on the weight of the dry wood. The calculated value is called the absolute moisture content and is simply referred to as the moisture content (W,%). Calculation formula:

W = (Gs-Ggo) / Ggo × 100%

Among them: W-absolute moisture content of wood;

Gs——Wet wood weight;

Ggoo-absolute dry weight.

2. The importance of mastering the moisture content of wood

Why do some wooden products such as wooden doors, wooden floors, wooden furniture, etc. have quality problems such as cracking and deformation after they are sold? How to reduce the loss of these problems to wood industry enterprises?

After the production of wood products is complete, the shape and material will not change. At this time, the key factors that determine the internal quality of wood products are mainly the wood moisture content and drying stress. Manufacturing companies need to correctly grasp the moisture content of wood products. When the wood product reaches the equilibrium moisture content when used, the wood at this time is the least likely to crack and deform
