Driving Factors
Excellent properties of thermally modified wood
(1) Good dimensional stability. Thermally modified wood can reduce the hygroscopicity of wood through high temperature heat treatment process, and by weakening the exchange capacity of wood and external moisture, so as to avoid deformation and cracking of wood caused by moisture changes during production and processing. Thermally modified wood is also more dimensionally stable because it is less prone to cupping and warping. Wood also has higher heat and weather resistance. If properly maintained, it will not chip, rot or warp over the years. Many of the products offered in this category are rated for 20 or 25 years of appearance.
(2) The corrosion resistance is improved. Since the heat treatment reduces the moisture content of the wood, and at the same time, the change of the macromolecule in the wood and the cracking of the hemicellulose produce substances that are toxic to the decaying fungus, which ultimately improves the decay resistance of the thermally modified wood, while the heat-treated wood improves the decaying fungus resistance of the wood. When the heat treatment temperature reaches 210 °C or above, the biological structure and chemical composition inside the wood will change, and the living environment of microorganisms that can cause wood decay, such as fungi, will also be destroyed. Moreover, the equilibrium moisture content of wood after high temperature heat treatment will generally drop by about 50%, which is also detrimental to the survival of microorganisms, thereby improving the corrosion resistance and durability of wood.
(3) Color stability and visual comfort. The color of the wood after heat treatment is generally brown, which is similar to the color of some precious wood, and the color of the heat-treated wood is uniform inside and outside, which is beautiful. Different colors of heat-treated wood can be obtained by adjusting the heat-treatment temperature and heat-treatment time, so as to realize the diversification of product varieties. The exterior initially attracted most architects, builders and homeowners to use heat-treated wood. Ash has a rich brown color and is seen by many as a warm addition to chilly modern buildings.
Environmental features of thermally modified wood
Thermally modified wood is a green and environmentally friendly product. It has antiseptic and repellent properties, but does not contain harmful substances. The process of thermally modifying wood not only improves the service life of wood, but also does not cause any harm to humans and animals during the production process. No harsh chemicals were used in the development of this product. Thermally modified wood is made of natural wood. No harmful chemicals are added in the production and processing process, nor does it cause any environmental pollution problems. It is a truly environmentally friendly green building material. Unlike pressure-treated wood, it also doesn't corrode metal. Thermally modified wood heat treatment is to make the wood components undergo physical and chemical changes at high temperature to achieve the purpose of improving wood properties. It is recognized as a green and environmentally friendly wood modification method.
More R&D investment
The durability and aesthetic appearance of thermally modified wood is gaining popularity, especially in high-end projects. This has led manufacturers to invest more in the research and development of thermally modified wood. For example, the Natural Resources Institute at the University of Minnesota in Duluth has a pilot-scale kiln to study the efficiency of thermal modification of underutilized Minnesota tree species. It is used in most operations due to the elevated temperature, 180 - 220°C, and the chemical composition of wood components changes after heating the wood.
Thermally modified wood is easy to handle
Heat modified wood is very easy to cut because there is no resin or sugar in the wood. It keeps tools and blades clean without stickiness.
Additionally, thermally modified wood has a lower weight and density, making the wood easier to machine. Thermally modified wood is also about 30% lighter when it comes out of the kiln than when it enters, making it easier to handle. At the same time, thermally modified wood is also flatter, eliminating the need for pre-drilled holes except at the ends of the boards. Finally, the lower internal stresses found in thermally modified wood also reduce material consumption during construction.
Key Development Trends
The growing trend of green building development
Green buildings are conducive to saving resources, protecting the environment, reducing pollution, and providing people with healthy, applicable and efficient space for use. Many countries promote the development of green buildings by formulating policy standards and encouraging technological innovation. According to a report by the United Nations Environment Programme, buildings and construction account for 35% of global energy consumption and 38% of carbon dioxide emissions, and the construction industry has become a major source of carbon emissions. Thermally modified wood is a natural and environmentally friendly building material, while maintaining stability under increased humidity, making it an excellent choice for furniture manufacturers and builders. In the production process of ThermoWood, the energy required for drying is mainly used for drying, accounting for 80% of the heat energy used. The total energy consumption is about 20% higher than the process of drying normal sawn timber to 18% moisture content. Energy consumption is almost equal due to shorter processing time compared to lower moisture content. In most cases, energy is produced by burning bark and wood waste. The graph below shows the energy consumption of some building materials used for processing and transport. The sources of energy are divided into renewable energy (bioenergy, wind, solar and hydro) and non-renewable energy (fossil fuels).
Global thermally modified wood market expected to continue to expand
Thermally modified wood, commonly referred to as heat-treated wood, has grown significantly over the past decade. Thermal modification was once considered an alternative to chemical preservatives. While this view remains to some extent, some manufacturers have softened their assertions that heat-treated wood is durable. Instead, the marketing focus has shifted to color variation and greater dimensional stability, emphasizing a higher level of durability compared to other naturally durable species. Heat-treated wood is not only widely used in courtyard fences, wooden windows, etc., but also in wooden furniture, and has great market potential.
The high-temperature heat treatment process uses more traditional heat-conducting medium, water vapor, as the heat-conducting medium.
The difference of high temperature heat treatment process is mainly reflected in: treatment medium, treatment temperature, treatment time and other conditions. If air is used as the heat-conducting medium, wood is easily combusted when contacted with oxygen at high temperature, and there are certain safety hazards; if molten metal is used as the heat-conducting medium, the heat treatment of wood is costly and difficult; if inert gas is the heat-conducting medium, a good heat treatment is required. It is also more troublesome to collect and prepare at the same time, and the cost is higher. Therefore, from the comprehensive consideration of economic efficiency and safety, it is better to use the traditional heat-conducting medium, water vapor, as the heat-conducting medium. The Thermo Wood high temperature heat treatment process is to first dry the raw wood or air-dried wood, and then perform steam heat treatment. The treatment temperature is generally 180°C to 250°C, and the treatment time is 0.5 hours to 4 hours. and cooling three stages. The production process of Plato Wood consists mainly of two heat treatment stages at different temperatures. In the first stage, the wood is subjected to heat treatment at 160 ° C to 190 ° C under the condition of gradually increasing pressure, and then the moisture content of the heat-treated wood is reduced by drying; The heat treatment time depends on factors such as the species, thickness and shape of the wood. Rectification is to use nitrogen as a medium to heat-treat wood with a moisture content of 12%. The treatment temperature is generally 200°C to 240°C, and the oxygen content does not exceed 2%. Precise temperature control is required during heat treatment, as small changes in temperature can have a very important impact on the final properties of the heat-treated material. Japan first researched and developed the wood fumigation heat treatment process, which is a process of heat treatment of wood by using waste wood as fuel and using the heat energy carried by the smoke released from the incomplete combustion of these fuels. The object to be treated can be logs or sawn timber with bark, and heat treatment is performed at a temperature of 80 to 200°C. First, raise the temperature to about 80°C and keep it for a period of time. At this time, the lignin softens, the moisture moves faster, the moisture inside the wood tends to be homogenized, the internal stress of the wood is reduced, and its tissue structure tends to be stable. The wood treated by this process can well improve its dimensional stability, durability and other physical properties, and the color change is relatively uniform.
