The selectivity of high-frequency heating of wood processing
發佈日期：2022/8/19
After decades of development, the application of high-frequency dielectric heating technology to wood processing has become very mature. Many furniture companies, plank factories, musical Musical instrument manufacturing companies, etc., enjoy the manufacturing advantages of the high efficiency and high quality brought by high-frequency technology.
High-frequency dielectric heating technology is widely used in the bamboo and wood processing and manufacturing industry, mainly because it has the advantages of high efficiency and high stability, and has the characteristics of "selective and rapid and uniform heating". This technology can be applied to wood panel jointing, bamboo and wooden frame assembly, wood drying, furniture board bending, composite wood veneer lamination, and other processes.
The selectivity of high-frequency heating
When the material is in a high-frequency electric field, the water molecules of the material will become active and produce violent motion, thereby generating heat energy, and the water in the adhesive is more than the water in the wood itself, so the most first affected by the high-frequency electric field, it is heated first and permeates into the plate. For example, after high-frequency wood jointing, we will find that the temperature of the jointed plate itself is low, and the glue between the wooden board is warm, which is called the selectivity of high-frequency heating-Adjust the equipment to a fixed frequency and then only heat the material that needs to be heated through the heating time.
The JYC high-frequency jointing machine adjusts to a fixed high-frequency power and lets the plates are evenly stressed, and quickly heats the glue between the plates, which saves energy more effectively, and makes the plates after jointing more stable.
