Learn to identify deep carbonized wood

Learn to identify deep carbonized wood

 

Carbonized lignin physical "anticorrosive wood," also known as heat-treated wood. From Europe, there are more than ten years of use history, of which the depth of carbonized wood is superior in wood, the depth of carbonization of wood sold in the market, there are many are imitation of deep carbonized wood to make a fake, to remind everyone at the time of purchase Be careful to choose, do not be fooled, let's learn together how to identify the depth of carbonized wood.


Deep carbonized wood identification methods


Odor: Deep carbonized wood has a carbonized layer because the surface is fired at high temperatures. All the wood is gathered near the ends of the wood. The wood smells a touch of carbon, and fake carbonized wood or substandard wood is pungent sour.


Weight: Carbonized depth of more carbonized wood, carbonated wood than the flat carbonized layer is also thick, the depth of the carbonized wood weight than the fake wood and surface carbonized wood should be light, light hand lift the timber can be identified.


Moisture content: deep carbonized wood baking time longer, the moisture content is relatively low, and the moisture content of wood is very uniform, the moisture content of other wood is not only high, the distribution is not uniform, water content measurement to rely on professional Wood moisture content measuring instruments.


Color: depth The color of wood mainly depends on the core material and the sapwood. The depth of color difference between core material and sapwood of carbonized wood is small, and the color of sapwood material is relatively dark. This is because the surface carbonized layer, Wood sapwood color is light, and the difference between the core material is also great.


Water absorption capacity: The depth of water absorption capacity of carbonized wood is relatively weak, this point can be clearly reflected in the paint, the wood can be painted experiment to verify the authenticity.


Hardness: Unlike ordinary wood preservative, the hardness of the depth of carbonized wood hardness inside the wood is too large, resulting in hardness is too large for two reasons, one is the hardness of wood itself, the second is the result of wood processing and baking, Just choose the hard object to test.


Contents: Deep carbonized wood processing within the wood after the evaporation of water, fungi, insects and so will kill, the wood material will soon become dry and clean, so if you touch the depth of carbonized wood will feel There are other impurities, fake wood will feel moisture, but also more sticky.


Production temperature: the depth of carbonized wood production temperature is 200 degrees, the production temperature of false wood is often only half of the depth of carbonized wood, or less, baking time will be less, if conditions permit, the user can field visits.
