Description

technical field [0001] The invention relates to a processing technology of recombined bamboo or recombined wood, in particular to a processing technology of recombined bamboo or recombined wood carbonization, and relates to the field of wood floor manufacturing. Background technique [0002] Carbonized recombined bamboo is a new type of bamboo composite material that reorganizes and strengthens bamboo after carbonization. It has the characteristics of high strength, good toughness, high hardness, and mildew resistance. It is widely used in indoor and outdoor floors, furniture, and structural buildings. materials, decoration materials, etc. However, most of the current carbonized recombined bamboo adopts high-temperature heat treatment processing technology, which has high energy consumption, long cycle, low production efficiency, and a mass loss rate of about 10%-20%, and a large amount of waste gas and waste liquid are discharged during the heat treatment process, polluting...
