Abstract

The invention discloses an ailanthus degreasing method. The method comprises the following steps that firstly, color-change-prevention pretreatment is carried out, wherein a sodium bicarbonate solution with the concentration ranging from 0.5% to 0.8% is sprayed three times, and the spraying interval is two days to four days; secondly, first-time digesting is carried out, wherein ailanthuses are put into a digester containing alkali liquor with the concentration ranging from 4% to 6% to be digested, the temperature is controlled to range from 30 DEG C to 50 DEG C, and the time is controlled to range from 2 hours to 4 hours; thirdly, the ailanthuses which are subject to treatment in the first step and the second step are put into a digester containing alkali liquor with the concentration ranging from 2% to 4% to be digested, the temperature is controlled to range from 30 DEG C to 50 DEG C, and the time is controlled to range from 2 hours to 4 hours; fourthly, rinsing is carried out, wherein the digested ailanthuses are rinsed with clean water two times to three times, the temperature is controlled to range from 20 DEG C to 40 DEG C, and the rinsing interval is 0.2 hour to 1 hour; and fifthly, drying is carried out, wherein a drying machine is used for drying the ailanthuses, and after the ailanthuses are cooled, the ailanthuses are painted with varnish. The method is low in cost, good in degreasing effect and free of affecting the color of the ailanthuses.

Description

technical field [0001] The invention belongs to the invention and relates to a wood processing method, in particular to a method for degreasing Chinese toon wood. Background technique [0002] In recent years, with the continuous improvement of the economic level and the improvement of people's living standards, people's requirements for furniture range from simple practicability, wider design to technology, health, environmental protection and other requirements, and the base material of furniture is the most basic Factors, various manufactured products based on wood-based panels have been gradually replaced by natural wood products due to their shortcomings such as environmental protection, economy, and defects of non-natural products. [0003] Natural wood products are more and more favored by consumers. However, if the oil, moisture and impurities of natural wood are not removed, they will slowly leach out of the surface of the material during the use of the finished pro...
