Wood conditioning method

Abstract

The invention discloses a wood conditioning method. The method comprises following steps of immersion treatment, primary heating and humidifying treatment, primary drying, primary cooling, secondary heating and humidifying treatment, secondary drying, secondary cooling and ventilation drying. According to the wood conditioning method, the high-temperature and low-temperature alternative drying manner is adopted to reduce the wood water containing rate, through immersion treatment, ammonium bicarbonate is guided into the wood, due to alkalescence of an ammonium bicarbonate solution, cellulose on the wood cell wall can be swelled up, introduction of subsequent heat and water flowing can be facilitated, according to high-temperature and high-humidity treatment, overheat water steam is used for forming partial pressure so as to move water out of the wood, through cooling, temperature gradient is used for diffusing water to the outer portion, the high temperature drying and the low temperature drying are alternatively carried out, the water containing rate of the wood is reduced to the proper range, the anti-mildew anti-corrosion property of the wood can be increased, consumed time is short, and energy consumption is small.

Description

technical field [0001] The invention relates to the field of wood processing, and more specifically relates to a method for maintaining the health of wood. Background technique [0002] Furniture not only needs to be maintained during use, but in fact, wood also needs to be "raised" during production and processing. Wood health preservation is the core technology of solid wood furniture production. If the temperature and humidity are not well controlled, the wood will appear inconsistent or uneven. Case. Since wood is a porous hygroscopic material, the level of moisture content will not only affect the cracking and deformation of furniture during use, but also have a great impact on the coating operation. Controlling the moisture content of air bubbles is an essential step in the production of solid wood furniture. Wood needs to adjust to the average relative temperature of most homes, but can still be affected by temperature and humidity in the air. Like human skin, wood...

AI Technical Summary

Problems solved by technology

[0003] The moisture content of natural wood is more than 50%. Through wood maintenance, the moisture content of wood can be reduced to less than 20%, which can destroy the parasitic conditions of bacteria and insects, increase the anti-mildew and anti-corrosion properties of wood, and prolong the service life of wood products. However, natural There are unsatisfactory disadvantages that wood is directly used to make furniture after ordinary drying treatment. For example, solid wood flooring is prone to mold and rot in a long-term humid environment. There are many reasons for wood mold. The common reasons for mold in this field are: The temperature in the hot stage or the initial treatment stage is too low, or the treatment time is too long; the temperature and humidity conditions of the wood in the early stage are too soft, the difference between the wet and dry bulb thermometers is small, or the value of the equilibrium moisture content is too large
