Abstract

The invention discloses a maple wood board degreasing method. The maple wood board degreasing method comprises the following steps that A, the maple wood board surface is sprayed utilizing a pentachlorophenol sodium solution with the concentration being 1-3% and placed for 0.5-1 h to obtain a product A; B, the product A surface is sprayed utilizing a sodium sulfite solution with the concentrationbeing 2-5% and placed for 0.5-1 h to obtain a product B; C, the product A is subjected to suffocating in steam with the temperature being 180-220 DEG C, the suffocating time is 1-2 h, and a product Cis obtained; D, the product C is placed into a container to be subjected to stewing utilizing an alcoholic solution with the concentration being 50-60%, the stewing time is 4-6 h, and a product D is obtained; E, the product D is dried with the temperature being 120-150 DEG C till the water containing rate of a maple wood board is 12-16%, and the maple wood board is cooled to 20-30 DEG C to obtaina finished product. The maple wood board degreasing method has the characteristics that no blue stain is generated, and the degreasing efficiency is high.

Description

technical field [0001] The invention relates to the technical field of degreasing methods for wood boards, in particular to a method for degreasing maple boards. Background technique [0002] Wood contains a lot of organic matter and nutritious inorganic matter, which is especially suitable for the growth and reproduction of wood-rot fungi, discoloration fungi, and insects. Maple boards are especially vulnerable to blue stain bacteria, which cause blue stains. Wooden boards are usually degreased and dried before use. [0003] In the degreasing method of ordinary maple wood boards, the maple wood boards are not subjected to blue stain treatment, which makes the surface of maple wood boards prone to blue stains. Furthermore, the degreasing method of common maple board takes a long time, making the degreasing efficiency low. Therefore, the degreasing method of common maple board has the problem that blue stain easily occurs on the maple board surface and the degreasing effic...
