Drying method for wood

Abstract

The invention discloses a drying method for wood. The drying method comprises the following steps that A, the wood is pre-planed, and the wood is cut into boards with the same size; B, the pre-planed wood is soaked with brine; C, the wood soaked with the brine is wrapped with tin foil paper and baked; D, the baked wood is coated with a wood anti-cracking agent, and then the wood is subjected to microwave and ultrasonic drying; and E, the wood obtained after microwave and ultrasonic drying is performed is subjected to thermal convection drying. By the adoption of the drying method for the wood, the moisture in the wood can be dried effectively, and the moisture content of the wood is less than 8.5% and meets the dry standard; the phenomena of cracking, deformation, bending and warping of the wood and the like can be avoided; the drying speed of the wood can be increased effectively, the time is shortened, the cost is lowered, and the stable mass production of the wood is achieved; and the quality of the obtained wood is stable, and the error between the moisture content and the target moisture content of dried products is small.

Description

technical field [0001] The invention belongs to the field of agriculture and forestry, and in particular relates to a wood drying method. Background technique [0002] Wood drying is an important part of wood processing and production, which directly affects the quality and utilization of wood, and is particularly important in the case of forest resources being increasingly scarce. If the drying quality of wooden furniture does not meet the technical requirements under different climatic conditions at home and abroad, it will easily lead to poor product quality stability, cracking, deformation and weak paint adhesion. At the same time, the moisture inside the wood is not easy to dry, resulting in the perishability and erodibility of the wood. In addition, if the drying process is unreasonable, especially during rapid drying, it is easy to cause deformation, bending and cracking of the wood, resulting in a decline in wood quality and waste. Therefore, adopting reasonable wo...

AI Technical Summary

Problems solved by technology

Wooden furniture materials are not dry enough. If the drying quality does not meet the technical requirements under different climatic conditions at home and abroad, it is easy to cause poor product quality stability, cracking, deformation and weak paint adhesion.

At the same time, the moisture inside the wood is not easy to dry, resulting in the perishability and erodibility of the wood.

In addition, if the drying process is unreasonable, especially during rapid drying, it is easy to cause deformation, bending and cracking of the wood, resulting in a decline in wood quality and waste
