Embodiment 1

[0018] Example 1: Using dried catalpa wood as raw material, a knife is carved into an animal "eagle" shape with a height of 30 cm, placed in a metal (such as steel) container with an exhaust port, and the temperature is increased by 0.2 ℃ per minute. The speed is slowly heated from room temperature to 40°C for 0.5 hours; then continue to increase the temperature in increments, each time heating is 40°C, holding for 0.5 hours; the highest rises to 400°C, after holding for 1 hour, the temperature is lowered at the same speed until the temperature in the metal container drops To room temperature, take out the inner material, which is a seamless activated carbon product. When the heating rate is controlled below 0.15°C / min, the heating can be continued without the need to raise and keep warm in stages.

Embodiment 2

[0019] Example 2: Using artificial wood boards with a length of 50cm and a thickness of 2.5cm as raw materials, put them in a metal container with an exhaust port, and slowly heat from room temperature to 40°C at a temperature increase rate of 0.25°C per minute, and keep the temperature for 1 hour; Then continue to heat up to 400°C at the stated speed, and then cool down at the stated speed after holding for 1 hour until the temperature in the container drops to room temperature, take out the materials in the container, and process the carbonized material into art that can be hung on the wall with a knife method. Products (such as engraving board paintings).

Embodiment 3

[0020] Example 3: Polish the surface of the carbonized eagle with silk cloth, and then use a writing brush to apply the absorbent silicon color powder (non-liquid) to the characteristic parts of the eagle according to the color of each part of the eagle, and then polish it with silk cloth. Serve beautiful eagle artwork.

Abstract

The present invention is the production, regeneration process and product of seamless active carbon product. The production process of the active carbon product includes setting timber or bamboo material inside one sealed container with exhaust port, raising temperature in certain rate gradually up to 600 deg.c, maintaining for certain time, lowering temperature in the same rate to room temperature to obtain the seamless active carbon product. The regeneration process is basically the same as the production process but has highest temperature of 400 deg.c and vacuum degree of 0.7-0.9 Pa maintained inside the container. The product may be further produced into artistic work through further processing, coloring and other steps and may be used in adsorbing harmful gas in air.

Description

Technical field [0001] The invention relates to a production and regeneration method of activated carbon products and decoration, decoration, art and craft products with adsorption function. Background technique [0002] In the prior art, although people have already started to use the adsorption function of activated carbon, its utilization range is very small, and it is mainly used for special protection and laboratories. [0003] On the other hand, with the development of society and economy, environmental protection has become more and more important. Various harmful gases released by hotel rooms and home furnishing materials, smoke caused by smoking, and indoor polluted air all seriously affect people’s health and need to be purified. . Summary of the invention [0004] The technical problem to be solved by the present invention is to provide a method for producing and regenerating seamless activated carbon products and its products in view of the problems existing in the p...
