Abstract: Mahogany furniture refers to furniture made of tropical hardwood trees such as red sandalwood, huanghuali, red rosewood, ebony, and wenge. It is the furniture material that Chinese people pay attention to to embody their identity since the Ming Dynasty. It is believed that the mahogany has not been dying for a hundred years, and it is still used in today's antique furniture. The mahogany wood is hard (the first one has been analyzed). From the point of view of dry research, it is all difficult to dry materials. The method of drying redwood in the past is to use natural air drying, and some are as long as two to three years. Redwood drying has been technically difficult since the Ming Dynasty.

1. Material factors: The most characteristic features of Ming-style mahogany furniture. Mahogany furniture refers to furniture made from tropical hardwood trees such as red sandalwood, huanghuali, red rosewood, ebony, and wenge. It is the furniture material that Chinese people pay attention to to embody their identity since the Ming Dynasty. It is believed that the mahogany has not been dying for a hundred years, and it is still used in today's antique furniture. The mahogany wood is hard (the first one has been analyzed). From the point of view of dry research, it is all difficult to dry materials. The method of drying redwood in the past is to use natural air drying, and some are as long as two to three years. Redwood drying has been technically difficult since the Ming Dynasty.

2. Process factors: Today's mahogany furniture production process still follows traditional techniques.

(1) The panel is not widened: the height of the high-end antique mahogany furniture door panel, table and several panels are as wide as possible, and there is no seam.

(2) Legs and borders do not match thickness: height, flat, sofa chair and other leg materials can not be squared regardless of the size of the section.

No integrated materials, glued materials, no glue, no nails. Because the craft does not match the board, not the square, it is the pure solid wood furniture in the true sense. Due to the wide range of mahogany furniture and various varieties, different parts require plate materials of different thickness specifications. Therefore, the specifications of mahogany sawn timber are very complicated. The thickness of the panel (16mm) is thin, but the width is natural, and the thin wall is easy to dry. However, it is easy to deform; the leg material thickness is above 50mm, and the thickness of some parts and materials even reaches 220mm. These thick plates and extra-thick plates, even if the ordinary furniture materials have a long drying cycle, the drying quality is difficult to control, so the mahogany is even more Difficult to dry.

3. Lack of knowledge and information: Since the Ming and Qing Dynasties, the main sources of mahogany furniture materials are Southeast Asia, southern China and Southwest China. With China's protection of forest resources, the state has introduced relevant policies. Redwood timber is almost entirely imported, and the source of rosewood timber has been transferred from these traditional regions to Africa, South America and the Pacific. The wood species have changed. The mahogany processing enterprises lack the access to resources information, and do not know the difference between the material properties, drying characteristics and traditional raw materials of most imported red wood species, and in these areas and research institutes. This phenomenon is relatively common with less communication. It has a lot of blindness in dry production. The lack of scientific knowledge, coupled with inadequate understanding and communication of drying technology, is also an important reason for the difficulty of drying redwood.

4. Production scale factors: Due to the raw materials, texture and production process of mahogany furniture and products, the price of mahogany furniture and products is very high, and it is difficult for ordinary consumers to purchase. The consumer market is very restricted, so the production scale is relatively small. There are many kinds of trees in redwood, and the price is also very high. Manufacturers do not dare to hoard raw materials. Each tree species can only be purchased in small quantities. It is difficult to classify and dry the plate materials of different specifications, and the scientific drying process is difficult to perform.

5. Management factors: Many enterprises have self-built mahogany drying kiln, equipment is self-made, and equipment performance is poor. It is difficult to ensure the correct implementation of reasonable technology; talents are not cultivated, and operations are not scientific. It is difficult to achieve true drying.
