Wood Characteristics

As an Anti-slip Vinyl Flooring Manufacturer, I will introduce you to one of the most common decoration materials - wood.

The physical and mechanical properties of wood mainly include water content, strength and swelling, and shrinkage:

1. Moisture content: is that the percentage of the quality of the water in the wood for a proportion of the caliber of the dried wood. Moist wood loses moisture in the dry atmosphere, and dry wood absorbs moisture in the surrounding air. After the wood is in particular temperature and humidity for a long time, a relatively steady water content will be achieved, and the evaporation and absorption of water tend to balance to achieve an equilibrium moisture content. The equilibrium moisture content varies with the temperature and relative humidity of the atmosphere. The moisture content of northern wood is roughly 12%, the moisture content of southernwood is roughly 18 percent, and the moisture content of timber in the Yangtze River basin is about 15%. From the architectural decoration, the moisture content of this 200-300 mm wide pine board normally decreases from 60% to 15 percent and requires approximately 10-15 days.

2.  Strength: The strength of wood is connected to thick cells in the wood that bear outside forces. The greater the number of such cells, the thicker the cell wall, the greater the intensity. The greater the bulk density of the wood, the higher the amount of late wood, the higher the strength.

3. Swelling and shrinking: The wood has significant swelling and shrinkage. When the wood is dried from a moist state to a fiber saturation point, its size doesn't change; drying proceeds, and when the adsorbed water from the cell wall evaporates, volume shrinkage occurs. Since that time, the wood moisture content continues to grow and won't re-expand.
