Problems solved by technology

These documents do not specify the specific scoring method, and the conventional scoring method of engraving several cracks on the log or large-size board can improve the permeability of the wood to a certain extent, but the long and irregular Cracks will affect the utilization of sawn timber in the later stage, and the improvement effect is limited

Abstract

The invention relates to a scoring method for wood difficult to penetrate and an application thereof. The scoring method for the wood includes the steps that a laser scoring technology is adopted to treat the wood difficult to penetrate; scoring figures are holes or seams; and the space between the scoring figures is 2-5mm, the depths are 5-10mm and the scoring figures are arrayed in the shape like a Chinese character 'pin' in a staggered mode. According to the scoring method for the wood difficult to penetrate and the application thereof, the laser scoring technology is introduced to a wood preservative treatment process, the penetration depth and homogeneity of an antiseptic chemical agent in the wood difficult to penetrate like eucalyptus, pinus sylvestris and Scots pines are increasedby optimizing the scoring pretreatment technology, biological deterioration resistance of heartwood of the wood is enhanced, a new thought is provided for antiseptic utilization of the common antiseptic wood like the eucalyptus, the pinus sylvestris and the Scots pines, the antiseptic efficiency of the wood is improved, the application range is widened and the additional value of products is increased.

Description

technical field [0001] The invention relates to a scoring method for impermeable wood and an application thereof, belonging to the technical field of wood preservation. Background technique [0002] As people pay more and more attention to the environment, the available large-diameter wood resources are relatively scarce, and the rational use of fast-growing plantation wood has become an important measure to alleviate the contradiction between wood supply and demand. Eucalyptus, poplar, and pine are recognized as the world's three fast-growing tree species. However, when used as outdoor materials, there is insufficient natural durability, and problems such as mildew, decay, and insects will occur during use, which limits the high value-added utilization of this type of wood for outdoor materials or building materials. For a long time, it has been mainly used in fiber papermaking, pallets, floor boards, plywood core materials or small-diameter agricultural support wood, etc....
