Embodiment 1

[0025] A eucalyptus solid wood door stem material moisture control technology, comprising the following steps:

[0026] S1: Cut the eucalyptus into boards, dry them at 52°C until the water content is 31%, use the stabilizer solution mixed uniformly with the stabilizer and water at a mass ratio of 1:20, soak for 18 hours under vacuum conditions, and then put the boards and Put the stabilizer together into the reaction kettle, heat at 62°C for 2 hours, after the reaction is completed, wait for natural cooling to take out the wooden board;

[0027] S2: Put the wood board into the pressure furnace for pressure drying process, monitor the moisture content during the process, when the moisture content of the dried wood board is 5% away from the required moisture content, return to normal pressure and stop drying;

[0028] S3: Adjust the temperature to 43°C and keep it until the moisture content of the board is 11%.

[0029] The vacuum condition is 20 Pa, and the temperature is main...

Abstract

The invention discloses a eucalyptus solid wood door stem material moisture content regulation and control technology, and belongs to the field of wood processing. The technology comprises the following steps that eucalyptus is cut into boards, the boards are dried at the temperature of 45-60 DEG C till the water content is 25-35%, a stabilizer is used for soaking the boards for 16-20 h under thevacuum condition, then the boards and the stabilizer are placed into a reaction kettle together, and after the reaction is completed, the boards are naturally cooled, and the boards are taken out; theboards are put into a pressure furnace to be subjected to pressure drying process treatment, the moisture content is monitored in the treatment process, and when the moisture content of the dried boards is 2%-10% away from the required moisture content, the normal pressure is recovered, and drying is stopped; and the temperature is adjusted to 38-50 DEG C, and the moisture content of the boards is kept to be 9-14%. By means of the technology, the water content needed by the stems can be accurately controlled, the quality of the stems is kept, and the situation that the stems crack after beingprocessed is avoided.

Description

technical field [0001] The invention relates to the field of wood processing, in particular to a technology for regulating the moisture content of stems of eucalyptus solid wood doors. Background technique [0002] With the continuous improvement of living standards, people's requirements for furniture grades are gradually increasing, and wooden furniture is especially popular among consumers. With the advancement of science and technology, the connection between different parts of the world is getting closer and closer. Domestically produced wooden furniture sells well all over the world. At the same time, it also brings technical problems to the wooden furniture industry: due to the large temperature difference between different regions on the earth, the humidity No, the frame wood of wooden furniture is very easy to crack and deform, thus destroying the appearance of wooden furniture and bringing great troubles to wooden furniture enterprises and consumers.
