Carbonized wood Floor from the Douglas fir material, elegant

Carbonized wood Background as early as in the 1930 of the 20th century, Germany and the United States have a study on heat treatment of wood, but did not achieve significant results. Later, Americans continue to study this subject in depth, and have made great achievements. In the 1990 of the 20th century, this technology in China has been greatly improved, and widely used.

Due to the humidity is Shanghai and other East China South China and other parts of Europe, so Carbonized wood Is very widely used in architecture. Wood, combined with advanced technology to the United States Southern pine studies carbonized wood. After at least 180 degrees Celsius heat treatment of wood, high temperature steam timber has a good antiseptic and insect features, in addition to steam, changed the original chemical properties of wood. After the high temperature carbonization of carbonized wood safety and environmental protection, wood become darker in color, in a constantly changing environment, carbonized wood stability is higher than normal untreated wood, moisture retention is greatly improved. At sufficiently high temperature carbonization of wood, its life expectancy far longer.

• Carbonized wood Processing

Carbonized wood carbonization process is approved by United States Association of carbonized wood certification. Nan Qi carbonized mainly: high temperature carbonization depth a (United States pine, 212 ° c treatment by high temperature, indoor and outdoor is available).

• Carbonized wood The carbonization process can be divided into the following main steps:

-1. heat up, dry heat heating high temperature kiln, kiln's temperature rises to 100 ° c. Then, when the temperature rose to 130 ° c and will remain stable, wood kiln drying start, water content fell to nearly zero.

Step 2 for thermal treatment.

Once kiln drying start, inside the kiln temperature will rise to between 185 ° c to 215 ° c. According to the carbonization wood is use after use, the temperature will continue to 2-3 hours.

Step 3. cooling and humidity control

Later stage is to use water spray to cool down; When the temperature drops to 80-90 ° c, and begin again the humidification, the wood moisture content reached 4-7% levels that are available.

Carbonized wood can prevent long Horn beetle, various types of erosion hazard of mold and fungus. Note: the carbonization wood cannot prevent the growth of algae on the surface of normal, these creatures live nutrients from the surrounding air, no structural damage to the wood. In many buildings, however they influence the aesthetic. To stop the growth of these organisms can be carbonized wood surface treatment.

• Carbonized wood Service life

United States architectural research limited review we provide proof, and came to the conclusion: Nan Qi carbonized wood (pine, high temperature carbonization depth category) have a service life of up to 32 years old.

• Carbonized wood density

Moisture content of 6% (=65% humidity, temperature =20 ° c environment) of the United States Southern pine carbonized wood density is 350-510 kg/m3. A few plates will have some natural changes. Carbonized wood density than the United States about pine 10%.

• Carbonized wood Nail holding power

In all of Cork, strong nail holding power of the Southern pine function. after drying after charring of the Southern pine, due to carbonization process of cell organization's position changes, enhancing grip nails.

Carbonized wood fire performance

According to the UK-13501 (test) charcoal wood showed that Nan Qi carbonized wood and untreated Cork, fire is d. Can fire the carbonization treatment in order to obtain better fire rating.

• Thermal properties of carbonized wood

Compared with natural cork, carbonized wood thermal conductivity is reduced overnight. According to our tests, carbonized wood (a, pine) 10 0.099W/coefficient of thermal conductivity λ (m k). Untreated timber of equal value 0.12 thermal conductivity W/(m k).

Carbonized wood color

Carbonized wood treatment temperature and time influence the color, the higher the temperature the surface the deeper the color will be. Because of the different density of Cork, their color changes are not the same. When carbonization wood is completely exposed to the UV light will fade unless anti-UV coating to protect it.

• Carbonized wood moisture

Nan Qi carbonized wood moisture content in the production process for five (RH 50%). This value depends on the atmospheric conditions change. The balance water is only half the equal value of untreated pine wood moisture content. (Table 1)

Carbonized wood quality control

Nan Qi of carbonized wood production process quality control and quality system is composed of United States certification by certification bodies. Quality certification system ensures that the carbonization wood is consistent product quality. External quality control is a part of the product certification process.

Carbonized wood environment

Carbonization of wood is a renewable natural resource. Nan Qi of carbonized wood raw materials are derived from a sustainable managed forests effectively is a registered trademark of PIONEER. Carbonized wood used in production of bio-energy, and based on life-cycle analysis, carbonized wood low load effect on the environment. Without adding any chemical substances in the heat treatment process, which itself does not contain any toxic or harmful ingredients. Emissions of organic compounds from the carbonized wood (VOC) only a fraction of normal emissions of pine.
