Carbonized wood Floor From the Douglas fir material Rich looking and beautiful

Carbonized wood Background As early as the 20Century 30, 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. To 20Century 90Age, 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. Wood is at least 180C high-temperature heat treatment, 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 charring are mainly as follows: depth of high-temperature carbonization A (United States pine, high temperature 212°CHandling, Interior and exterior are available).

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

-Steps 1.Heat, dry heat heating high temperature kiln, kiln temperature increases rapidly to 100°C. Then, when temperature reaches 130°CAnd stable when wood kiln drying start, water content fell to nearly zero.

-Steps 2.Heat treatment

Once kiln drying start, rises in temperature within the kiln to 185°CTo 215°CIn between. According to the carbonization wood is use after use, the temperature to continue 2-3Two hours.

-Steps 3.Cooling and humidity control

Later stage is to use water spray to cool down; When the temperature drops to 80-90°CAgain start humidification, the wood moisture content reached 4-7%Available levels.

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, deep high temperature carbonization AClass) long service life 32Year-long.

• Carbonized wood density

Moisture content of 6% (Humidity =65%Temperature =20°CThe 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 United States pine about10%.

• 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 UK 13501(Test )Crown charcoal wood showed that Nan Qi carbonized wood and untreated softwood, like fire is DLevel. 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 reduces 20-25%. According to our tests, carbonized wood (A, Pine) coefficient of thermal conductivity λ10For 0.099W/(m K). Equivalent thermal conductivity of untreated lumber 0.12 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 5-7%(Relative humidity 50%). This value depends on the atmospheric conditions change. The balance water is only half the equal value of untreated pine wood moisture content. (Table1)

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.
