The microwave drying and shaping of wood is a new technology. It has the advantages of uniform heating, fast drying speed, good shape, and good quality, which is conducive to continuous and automated production.
The distinctive feature of microwave drying in wood is that the heat is not transmitted from the exterior of the object, but the microwaves are directly heated by the moisture contained in the material and absorbed by the wood itself. Because of the evaporation of moisture on the surface of the material, the internal temperature of the material is higher than the surface, so that the internal pressure of the material forms an outward pressure difference, which accelerates the surface migration of moisture. Therefore, the microwave drying of wood is much faster than the convective drying speed, 20-30 times faster. . Than the far infrared and steam drying energy consumption reduced by more than 25%.
The microwave drying of the material can make the internal temperature of the wood higher than 60°C, and the parasitized eggs in the material can be quickly killed to achieve the functions of anti-mite and anti-mildew. For a variety of different types of wood to take the appropriate microwave heating speed, to achieve the best process conditions, get the best benefits.

This is one of the biggest characteristics of stretch film packaging. With the strong winding force and retraction of the film, the product is compactly and fixedly bundled into a unit, so that the scattered small pieces become a whole, even in unfavorable environments, the product does not have any looseness or separation, and is not sharp and sharp. The edges and stickiness to avoid damage.
