Abstract

The invention relates to the technical field of wood treatment, and discloses a treatment method for eliminating bluing of rubber wood. The blued rubber wood is subjected to physical and chemical treatment methods so that bluing bacteria and other accessory bacteria on the surface and in the interior can be deeply and effectively removed, and bluing spots can be well eliminated; the adopted treatment mode is simple, blue color spots in the blued rubber wood can be effectively removed, the original color of the rubber wood is stabilized, the original quality of the rubber wood is kept for a long time, the problem that the quality of the rubber wood is reduced due to the poor prevention and treatment effect caused by the high bluing infection speed is solved, the method has the advantages offavorable color spot elimination effect on the blued rubber wood and low treatment cost, and can be popularized and used in production. Economic loss and processing cost brought to rubber wood processing enterprises due to bluing are reduced.

Description

technical field [0001] The invention belongs to the technical field of wood treatment, and in particular relates to a treatment method for eliminating blue stain of rubberwood wood. Background technique [0002] Rubber wood is a plant that produces rubber latex. It is the trunk of the rubber tree and is a subtropical tree species. When the tree is old, its trunk can be used to make furniture. With the development of the furniture market, rubber wood is more and more widely used in furniture, flooring, wood core boards, etc. Rubber wood has elegant color, beautiful texture, dry shrinkage, light to medium density, good mechanical processing and finishing performance, but because it contains about 8% free sugar and starch (general wood is only 1%-3%), it is easy to mold Mutation, moth and decay. [0003] After the trees are felled, there is no timely and effective health care treatment, but the whole tree is directly placed on the wet soil, where it is exposed to wind, rain ...
