Processing method for sequoias product

Abstract

The invention relates to the technical field of processing wooden handicrafts, and discloses a processing method of metasequoia wood products. The chemical composition of the treated metasequoia wood changes, the free hydroxyl functional groups are greatly reduced, and the hygroscopicity and water absorption of the wood are significantly reduced. Cellulose is degraded into free acid, which cuts off the food chain of decaying bacteria, improves antisepsis, compressive strength, and hardness, volatilizes the content of wood, facilitates processing and finishing, and is easy to maintain. During the production process of pressure and high temperature heat treatment wood Only water vapor and temperature are involved, no chemicals are added, and no foreign substances are added. Therefore, the use of pressure and high temperature heat treatment of wood is environmentally friendly and will not pollute the environment. At the same time, because the equilibrium moisture content of treated wood decreases during use, Dimensional stability is greatly improved. After finishing, Metasequoia wood products are uniform in color, durable, stable in material and not easy to deform.

Description

technical field [0001] The invention belongs to the technical field of wood handicraft processing, and in particular relates to a processing method of metasequoia wood products. Background technique [0002] Handicrafts are for appreciation, and their artistic value makes handicrafts can be seen everywhere, but the most appreciated handicrafts are still wooden handicrafts. Most of the wooden handicrafts are made by hand or machine, and they are processed directly on the dried wood. Most of the unearthed wooden handicrafts are lifelike and lovable. Wooden handicrafts use various kinds of wood as the main raw material. Some are machine-made, some are purely hand-made, some are half-machine and half-handmade, with fine workmanship, simple design, different styles, natural color, novelty and uniqueness. They are unique handicrafts in China. . Metasequoia is a fast-growing tree species with strong light-loving and strong adaptability to environmental conditions. Since Metasequ...

Moreover, the lines of fir are very beautiful, and the color distribution of fir is also very uniform, which is very good in terms of material and texture, but there is a big disadvantage of metasequoia wood products: it is difficult to maintain, which is opposite to the quality of wood. It is related to softness. When the wood is soft, the bonding force of the wood itself is small. Under the action of the environment and external forces, the wood itself may be damaged, thereby increasing the peeling rate of the metasequoia surface paint film.
