Processing method for wood rich in grease

Abstract

The invention discloses a processing method for wood rich in grease. The processing method comprises the steps that the wood is sent to vacuum drying equipment to be subjected to drying pretreatment;the temperature inside the vacuum drying equipment is increased at the first temperature rise rate to a first preset temperature upper limit; the temperature inside the vacuum drying equipment is increased at the second temperature rise rate to a second preset temperature upper limit, and the second preset temperature upper limit is larger than the first preset temperature upper limit; the vacuumdrying equipment is closed to place the wood obtained after slow cooling to the ventilation position, and grease objects are removed after coagulation and air drying of the grease discharged to the position of the cross section of the wood; and the temperature is slowly increased in the vacuum drying box, and reasonable matching of the grease is achieved on the premise that most grease is reserved. By means of the above method, reasonable matching of the grease is achieved on the premise that most grease is reserved, and the wood is even, bright and attractive in color and luster.

Description

technical field [0001] The invention belongs to the field of wood treatment, and in particular relates to a treatment method for oil-rich wood. Background technique [0002] Grease, the "oil" in wood, is inherently a resin. Oil has always been an important indicator for judging the quality of a piece of wood. The higher the oil content of wood, the smoother it feels when touched, smooth and wear-resistant, not easy to crack, and presents a shiny side of furniture. Mahogany is rich in oil, and the mahogany furniture made of it is hard in texture and soft in color, so the mahogany material can usually be preserved for hundreds or even thousands of years, and can maintain the color of the mahogany log itself. Mahogany is a kind of wood with higher density, rich in oil and minerals, so it usually appears dark purple-brown, and even some mineral-rich sections are close to black. However, when processing oil-rich wood, the rich oil often affects the processing characteristics an...

AI Technical Summary

Problems solved by technology

However, when processing oil-rich wood, the rich oil often affects the processing characteristics and surface quality of the wood, reduces the dimensional stability of the wood, and restricts the use of this type of wood

[0003] The existing wood is usually treated with chemical treatments such as waxing, boiling wax, wax injection, etc., which deepens the color of the wood and the furniture made into pure black, resulting in a large difference in color between the wood and traditional mahogany

Traditional color treatment methods are often carried out with chemical reagents. The typical document is the invention patent "A High-end Modification Method for Wood" with the authorized announcement number CN 1027 尒尓408B, which uses dyes and synthetic resins to impregnate ordinary wood. Although the surface color of the wood is improved, it is not suitable for the presentation of the color of high-end wood itself, and the use of chemical substances covers the original characteristics and smell of wood and other mahogany, and is harmful to the human body
