Abstract

The invention discloses a wood drying method, which comprises the following steps: 1 low temperature preheating, 2 preliminary-stage processing, 3 ventilating and drying, 4 middle-stage processing, 5 secondary drying, 6 final processing, 7 lowering humiture and surface drying. The technical scheme of the wood drying method well resolves the problem of wood mustiness caused by over low temperature in the low temperature preheating stage or the preliminary processing stage, thereby being suitable for industrial production.

Description

technical field [0001] The invention relates to a method for treating wood, in particular to a method for preventing mildew, and belongs to the field of wood processing. Background technique [0002] Pure solid wood furniture has natural color and beautiful pattern, stable and durable structure, and it is also the most ideal furniture in history, which is deeply loved by people. Therefore, wood is the most ideal material for making high-end furniture in the world. [0003] However, there are also unsatisfactory disadvantages in that natural wood is directly used to make furniture only through ordinary drying treatment: as the floor of the kitchen, bathroom or north-facing room, it is easy to mold and rot in a long-term humid environment. This is an unsolvable problem in solid wood furniture itself, and it is also the most troublesome place for many solid wood furniture manufacturers. [0004] There are many reasons for wood mold. The common mold in this field is mainly caus...
