Drying Effect Demonstration
One: Wood Drying
It is the process of separating moisture from wood, which is divided into primary drying, secondary drying, and maintenance balance. Generally, heating in an environment below 100 degrees Celsius causes moisture to turn into vapor and evaporate, resulting in a reduction in volume and weight. During the production process, moisture regain can lead to deformation, bulging, and cracking due to the addition of moisture (glue) during bonding. To address this fundamentally, two approaches are taken: first, achieving secondary drying and maintenance balance of moisture; second, altering the fiber characteristics of the wood through high-temperature hardening to eliminate residual stress in the wood, stabilize its properties, and remove adverse factors.
II. Wood Hardening:
The wood fiber molecules transition from a tubular structure to a networked crystal atomic structure within the range of 150-200 degrees. The proportion of change is determined by the temperature and duration. It lies between wood and charcoal, with manufacturers deciding the ratio based on their specific applications. Indoor materials are typically only hardened, with the wood fiber molecules undergoing a mild high-temperature treatment to eliminate some activity, reduce residual stress in the wood, and maintain stability without deformation. It also preserves elasticity and impact resistance.
Section 3: Wood Carbonization
The wood fiber molecules transition from a tubular structure to a reticular crystal atomic structure within the range of 200-250 degrees Celsius. The proportion of change is determined by the temperature and duration, placing the wood between wood and charcoal. Manufacturers decide the ratio of wood to charcoal based on their specific applications. Outdoor materials typically opt for carbonization, which is categorized into light, medium, and deep. Light carbonization is usually on the surface, used for adjusting color differences and shaping; medium carbonization is suitable for outdoor wood products, highly adaptable to the environment; deep carbonization is less commonly used in wood products due to its fragility, lower strength, poor nail holding, and difficulty in contacting soil and water. Benefits include high stability, no color variation, anti-corrosion, environmental friendliness, and ease of reprocessing after oil and fat removal.
Four: Compliant with wood products processing requirements:
Our company, after market research and drawing on advanced domestic and international experience, has developed a high-temperature hardening equipment. Within the range of 150-200 degrees Celsius, it controls the hardening degree of wood through computer control, achieving good results. It maintains the effective physical properties of wood, including elasticity, impact resistance, strength, high stability, and resistance to deformation and cracking, while avoiding the defects of carbonization, which makes the wood brittle and prone to breakage.
