Novel carbonized wood production method

Abstract

The invention discloses a novel carbonized wood production method which comprises the three steps of wood impregnation pretreatment, wood high temperature treatment and wood surface treatment, wherein an impregnation modified liquid in the wood impregnation pretreatment is a mixed solution composed of a sodium silicate solution, nano silicon dioxide powder, nano titanium dioxide powder and a zinc borate solution with the weight part ratio of the sodium silicate solution to the nano silicon dioxide powder to the nano titanium dioxide powder to the zinc borate solution being (4-6) to (0.5-0.7) to (0.3-0.7) to (1-3); and during the cooling period in the wood high temperature treatment, a batch-type steam injection method is adopted for cooling, the temperature in a carbonization chamber is decreased to 115 to 125 DEG C at the speed of 7 to 12 DEG C/h, and the temperature is maintained for 1.3 to 1.7 h, then, the temperature is decreased to 90 to 100 DEG C at the speed of 4 to 6 DEG C/h, and the temperature is maintained for 0.5 to 0.9 h, the wood is subjected to humidity conditioning and moisture regaining treatment for 7 to 9 h through steam with the same temperature, the moisture content of the wood is regulated back to 4 to 7%, and finally, the temperature naturally drops to the room temperature.
