Board balance health-preserving chamber and board health-preserving method

Abstract

The invention relates to a board balance reconditioning chamber and a method for reconditioning boards. The inside of the board balance reconditioning chamber is provided with a dehumidifier, a humidifier and temperature control equipment, and the middle part of the board balance reconditioning chamber is provided with an air flow guide device. The method for reconditioning boards comprises the following steps: 1) piling boards in the board balance reconditioning chamber; 2) adjusting the temperature and humidity of the board balance reconditioning chamber and determining the board processing time according to the preset water content range of the boards to balance the water content of all parts of the boards and to release the inner stress of the boards in a constant temperature and humidity environment; and 3) determining the water content of the boards and completing the reconditioning treatment when the water content of the boards reaches a preset value. The invention provides the constant temperature and humidity environment with flowing air to balance the water content of all parts of the boards, to release the inner stress of the wood fibers and to reduce the drawbacks of wood floors such as deformation and bending, thereby improving the percentage of cut-turn and the stability of the quality of the wood floors.

Description

technical field [0001] The invention relates to the processing technology of boards, in particular to a balanced health-preserving room for boards and a health-preserving method for boards. Background technique [0002] Multi-layer composite wood flooring is composed of two-layer, three-layer or multi-layer veneers, which are hot-pressed or cold-pressed into wooden floor blanks after sizing. Due to the different characteristics of the wood itself and the composition of wood fibers, the internal stress of the wood veneer after drying cannot be fully released, and the moisture content of the wood is not uniform in various parts of the board. For example, in the same substrate slab Among them, some veneers have a moisture content of 7%, and some veneers have a moisture content of 14%. The composite wood floor composed of such multi-layer veneers will crack and crack when the finished product is sold and used in the market. Deformation, shrinkage, bending, delamination and othe...
