Drying treatment technology of wood sheets

Abstract

The invention discloses a drying treatment technology of wood sheets, and belongs to the technical field of wood processing. The technology comprises the following steps of 1, sheet processing; 2, primary sheet drying treatment; 3, secondary sheet drying treatment; 4, tertiary sheet drying treatment; 5, sheet drying post-treatment. The phenomenon that wood sheets deform, crack and bend in the drying process can be well prevented, the drying time is shortened by 40-60%, the wood sheet cracking probability is lowered by 2 times or more, the surface of the dried wood sheet is more smooth, and the good application and popularization value is achieved.

Description

technical field [0001] The invention belongs to the technical field of wood processing, and in particular relates to a drying treatment process of veneer wood. Background technique [0002] Wood must be pretreated before it is put into use, and among them, wood drying is an important link and the most critical process in the first step; the quality of drying directly affects the utilization rate of wood and the processing of subsequent processes, directly affecting It affects the final quality of wood products. [0003] Nowadays, the wood whose thickness is not greater than 12cm is often called veneer wood. The drying method of the prior art mostly adopts the kiln drying method, that is, the veneer wood is piled up in the drying kiln, and the air in the kiln is repeatedly heated and steam is sprayed into the kiln. And blast the air and steam in the kiln to dry the veneer wood. Since the best drying standard of the veneer wood cannot be grasped, various data settings are unr...

[0003] Nowadays, the wood whose thickness is not greater than 12cm is often called veneer wood. The drying method of the prior art mostly adopts the kiln drying method, that is, the veneer wood is piled up in the drying kiln, and the air in the kiln is repeatedly heated and steam is sprayed into the kiln. And blast the air and steam in the kiln to dry the veneer wood. Since the best drying standard of the veneer wood cannot be grasped, various data settings are unreasonable during the drying process, causing the veneer wood to dry during the heating stage. , it will eventually cause problems such as cracking, warping, and deformation of the veneer wood. At the same time, the drying efficiency of this method is not high, and the energy consumption is relatively large.
