High-carbon preservative bamboo carbonizing method

Abstract

The invention discloses a high-carbon preservative bamboo carbonizing method, which comprises the steps of 1) removing tabasheer from a fresh bamboo to obtain a bamboo splint, and drying the bamboo splint; 2) paving the bamboo splint flat on a disposing rack, measuring the paving thickness h of the bamboo splint, and setting a carbonizing standard according to the paving thickness h; 3) heating by phases according to the set carbonizing standard and keeping the temperature of each phase until all organic matter clearance of the bamboo splint inside a carbonization kiln reaches a maximum value while satisfying a flexibility requirement; 4) after carbonization, cooling the carbonization kiln by atomization cooling to obtain the high-carbon preservative bamboo. According to the invention, the preservative performance of the bamboo can be greatly improved; bamboo stacked in different heights can be carbonized uniformly. In this way, the color of the carbonized bamboo is uniform; color difference is avoided; advantages like short production period, simple operation, safety and environmental protection are provided.

Description

technical field [0001] The invention relates to a carbonization method, in particular to a carbonization method for high-carbon anticorrosive bamboo. Background technique [0002] The panels made from bamboo are widely used in flooring, wall panels, furniture and other decorative panels or other industries because of cheap raw materials, easy availability, low cost, beautiful appearance, high strength and good performance. In particular, moso bamboo grows fast and is rich in resources. It can not only replace wooden boards, save wood resources, but also benefit the protection of the ecological environment. Therefore, it has been paid more and more attention by the country and the industry. However, because the content of organic matter such as starch and sugar in bamboo is higher than that of wood, it is more prone to mildew, browning and insects than wood during the storage, processing and use of bamboo products, which affects the quality of bamboo products. Beauty and lon...

Problems solved by technology

On the one hand, due to the high-pressure carbonization of steam, it is difficult to raise the temperature of bamboo to a temperature sufficient to completely remove the organic matter; on the other hand, due to the high-pressure carbonization of steam, the control sensitivity to temperature is not very strong

High-temperature carbonization refers to placing the dried bamboo in a normal-pressure carbonization chamber, and raising the temperature of the bamboo to 100-300°C through heat-conducting oil. The process parameters change greatly during the production process of this method. The constant temperature time of the stage is different, and there is no uniform standard for the highest temperature of heating, which leads to different shades of bamboo after carbonization, which may easily lead to insufficient or excessive removal of organic matter, which will lead to a decrease in the hardness of the bamboo, and then make the bamboo produced. Board products often cannot meet international standards, and cannot maximize the advantages of high-temperature carbonization of bamboo
