Embodiment 1

[0019] (1). Put rice husks or 1 mm to 2 cm bamboo and wood waste into the converter for carbonization respectively. The carbonization temperature is 250-600 ° C, and the carbonization time is 5-30 hours to obtain rice husk charcoal or bamboo charcoal spare.

[0020] (2). Add water to the rice husk charcoal or bamboo charcoal obtained in step (1), and the weight ratio of charcoal to water is two to one; the rice husk charcoal and bamboo charcoal mixed with water are respectively packed into a multifunctional activated carbon converter for Activation, the activation time is 5-30 hours, and the activation temperature is 500-600°C to obtain activated carbon; the activated carbon prepared under this condition, the iodine adsorption value of rice husk activated carbon is above 600 mg / g; the iodine adsorption value of bamboo and wood activated carbon Above 800 mg / g.

[0021] (3). The rice husk or bamboo wood activated carbon obtained in step (2) is respectively pulverized to 4-300 m...

Embodiment 2

[0027] (1). Put rice husks or 2 cm to 15 cm of bamboo and wood waste into the counter-burning furnace for carbonization. The carbonization temperature is 400-500 ° C, and the carbonization time is 60-90 hours to obtain rice husk charcoal. Or bamboo charcoal for later use.

[0028] (2). Add water to the rice husk charcoal or bamboo charcoal obtained in step (1), and the weight ratio of charcoal to water is two to one; the rice husk charcoal and bamboo charcoal mixed with water are respectively packed into a multifunctional activated carbon converter for Activation, the activation time is 60-70 hours, and the activation temperature is 600-900°C to obtain activated carbon; the activated carbon prepared under this condition, the iodine adsorption value of rice husk activated carbon is above 600 mg / g; the iodine adsorption value of bamboo and wood activated carbon Above 800 mg / g.

[0029] (3). The rice husk or bamboo wood activated carbon obtained in step (2) is respectively pulve...

Abstract

An activated carbon board for decorative purpose to clean air is prepared from rice husk and the rejected bamboo and wood through preparing activated carbon, mixing it with high-molecular aquatic isocyanate adhesive, and die pressing.

Description

technical field [0001] The invention belongs to the field of plywood preparation in the production of wood-based panels, in particular to activated carbon panels prepared from rice husks and bamboo and wood waste. Background technique [0002] Activated carbon has a strong adsorption capacity and is widely used. At present, most of the boards used for indoor, vehicle and ship interior decoration, and furniture are wood, plywood, particle board, etc. Using bamboo raw materials to process into boards is a new type of boards developed by people in the industry. Disclosed bamboo plywood manufacture method as CN87100368. Using moso bamboo as raw material, the inner and outer bamboo joints are removed, split, boiled in water and waxed twice to soften, and then pressurized and flattened. After being planed, dried and shaped, the pressured and flattened bamboo can be used as a panel, backboard or core board for the production of plywood. Made of plywood, its use is similar to th...
