Wood surface minimally invasive device and wood surface treatment method

Abstract

The invention discloses a wood surface minimally invasive device and a wood surface treatment method. The wood surface minimally invasive device comprises at least a driving roll and at least a driven roll. The driving rolls and the driven rolls are arranged in pairs. The roll surfaces of the driving rolls and the driven rolls are provided with thorns. The surface of wood which is treated by the wood surface minimally invasive device is intact and does not have deep nick traces. Using the wood surface treatment method of the wood surface minimally invasive device can shorten the penetration distance of a wood modifying agent on a wood fiber direction, and penetration depth vertical to the fiber direction. The method can especially effectively impregnate heartwood whose permeability is poor and tree species which are hard to impregnate under the condition of not damaging the surface of the wood.

Description

technical field [0001] The invention relates to a wood surface minimally invasive device and a wood surface treatment method. Background technique [0002] As a renewable and environmentally friendly material, wood is widely used in places closely related to people's lives, such as construction, furniture, decoration, ships, car floor, wind power blades and other fields. It has high strength-to-weight ratio, easy processing, and low processing energy consumption. , small environmental load, decorative effect and other characteristics are incomparable to steel and cement materials. However, as an organic polymer material, wood itself has problems such as flammability, perishability, insect infestation, and unstable size, especially artificial fast-growing wood, which has low physical and mechanical properties, which greatly restricts its application. In order to overcome the above shortcomings of wood, people implement functional improvements to wood, for example, use flame ...

Problems solved by technology

However, these methods also have their limitations. For species with poor heartwood permeability, it is difficult to achieve a penetration of 2-3mm on the surface of the wood, especially in the case of quarter-cut wood.
