Problems solved by technology

Since the wood carbonization treatment process is still in the research stage, the quality of the wood treated by the existing process is unstable, and it is easy to cause quality problems of deformation, and the carbonization treatment cycle is long, which greatly increases the production cost, so the use effect is not ideal.

Embodiment Construction

[0018] Embodiments of the present invention: the present invention comprises the following steps,

[0019] a. Palletize the wood neatly and press 1t / m on the top of the wood pile 2 The standard pressurized steel plate frame poured concrete briquettes, and then loaded into the wood carbonization equipment.

[0020] b. After the wood is loaded into the carbonization equipment, it starts to heat up. The first stage of temperature rise adopts a stepwise continuous temperature rise method, and the temperature is raised to 130°C at a rate of 5°C every 5 hours, that is, it is rapidly raised from the original temperature by 5°C and then kept for 5 hours, and then the temperature is raised to 130°C in the same way. The temperature is 130°C higher than that of 130°C for 5 hours, and the first heating stage ends. The types of wood to be processed are different, and the maximum temperature is determined according to the density of the wood. The temperature of high density is high, and t...

Abstract

A carbonization process for increasing the quality of wood by continuous gradient heating method includes such steps as heating to 120-140 deg.C, eating to 160-240 deg.C, spraying atomized water for slowly cooling to 100 deg.C, filling the saturated steam at 100 deg.C to return the water content back to 4-6%, and cooling to 15-30 deg.C.

Description

technical field [0001] The invention relates to a wood carbonization treatment method, which belongs to the technical field of wood product production technology. Background technique [0002] How to functionally improve wood, turn it into a high-quality raw material for the production of high value-added wood products such as floors and furniture, and develop and produce new wood products will promote the sound development of my country's plantation forest area and expand many The source of raw materials for wood processing enterprises, reducing raw materials and transportation costs, improving the purchasing power of residents and the market competitiveness of enterprises have great social significance, ecological and environmental benefits and economic benefits. Among the many existing functional improvement methods, wood carbonization treatment technology has the characteristics of good dimensional stability, corrosion resistance and weather resistance compared with untre...
