Wood processing technology

Wood processing, using wood as raw material, mainly adopts mechanical or chemical methods to process, and its products still maintain the basic characteristics of wood. In the forest industry, wood processing industry and chemical processing of forest products are the follow-up industries of forest harvesting and transportation, and are important departments for comprehensive utilization of wood resources. principle

Wood processing technology includes basic processing technologies such as wood cutting, wood drying, wood gluing and wood surface decoration, as well as functional processing technologies such as wood protection and wood modification. Cutting methods include sawing, planing, milling, drilling and grinding. Due to the influence of wood texture and texture, the cutting method is different from other materials. The moisture content of wood also affects cutting, such as wet cutting of veneer making and wood chip production, and dry cutting of most processed parts. Drying usually refers to the drying of finished products. The drying of other wood materials such as veneer, wood shavings and wood fibers is an indispensable part in the production process of plywood, particleboard and fiberboard respectively. The emergence and development of wood adhesives and gluing technology are not only the main factors to improve the level of wood processing technology, but also the premise to produce recycled wood and improve wood, such as building blocks and glued wood at all levels. The purpose of wood surface coating is firstly to protect wood, such as traditional tung oil and raw lacquer coating; Later, it gradually evolved into decorative. In fact, any surface decoration has a protective effect. The surface decoration of wood-based panels can be carried out at the same time during the manufacturing process. Wood protection includes wood preservation, moth prevention and wood flame retardant. That is, by brushing, spraying and soaking the corresponding chemicals, the wood can be prevented from being invaded by fungi, insects, marine moths and other organisms. Or stop the destruction of fire. Wood modification is a technical treatment to improve or improve some physical, mechanical or chemical properties of wood. When the above processing technology is adopted, the reactions produced by different tree species can show different properties, which are called the technological properties or processing characteristics of wood.

trait

Wood processing technology is a subject that studies wood processing technology. Based on wood science, it applies theories and methods in the fields of physics, chemistry, biology, mechanical engineering, thermal energy engineering and so on, and is a multi-disciplinary comprehensive discipline.

superiority

Wood has the advantages of light weight, high specific strength, good elasticity, impact resistance, rich and beautiful texture and easy processing, and has been listed as an important raw material since ancient times. Wood industry plays an important role in the national economy with its low energy consumption, less pollution and renewable resources. At present, products have developed from primary processed products of logs, such as poles, potholes, sleepers and sawn timber, to reprocessed products of wood, such as building components, furniture, vehicles, ships, stationery, packaging containers and other wood products, and even reprocessed products of wood, such as various man-made boards and glued wood, making the wood industry form an independent industrial system.

disadvantaged

The fire protection performance is poor, it is easy to rot and deteriorate, and it is easy to be eaten by insects, so it requires higher humidity and other use environments.
