Technical field
The present invention relates to timber improving technology field, be specifically related to a kind of heat treatment method decorating panel.
Background technology
The decoration panel of usual solid wood furniture incrustation is not past heat treatment, the moisture content making decoration panel is high, it is easy to the impact being subject to ambient temperature and humidity change causes that tile deforms, the even cracking that tile deformation is big, cause furniture item to deform, be substantially reduced product quality.
Along with a large amount of minimizings of the hard broadleaf forest reserves, the rise in price of timber, therefore, a lot of enterprises all start to make sheet material with cheap fast growing wood for raw material, substitute hard broad-leaved wood.But fast growing wood fast growth, material-structure changes greatly, it is easy to deformation, quality compared with hard broad-leaved wood, and cannot be susceptible to go mouldy, affect the decoration of furniture surface, greatly reduce quality and the serviceability of sheet material.Therefore, sheet material is carried out functionality improvement, drops bottom plate moisture content, reduce humiture change on the impact of sheet material flatness, improve board dimension stability, extend sheet material and be particularly important service life.
Summary of the invention
It is an object of the invention to for the deficiencies in the prior art part, it is provided that a kind of heat treatment method decorating panel, its production efficiency is high, thermal effectiveness is good, excellent in stability, it is possible to make the mechanical property loss in carbonization process of the decoration panel minimum, not easy to crack and deformation.
The heat treatment method of decoration panel, comprises the following steps:
(1) dry: by the decoration panel that sheet fabrication thickness is 4-5mm, to be dried to moisture content 20-28%;
(2) it is rapidly heated: dried decoration panel is put into carbonizing kiln, is warming up to 110-125 DEG C with the speed of 50-60 DEG C/h;
(3) insulation: be incubated 0.5-1 hour at 110-125 DEG C;
(4) humidification insulation: humidifying and raise humidity, wet bulb temperature, to 100 DEG C, temperature 105-120 DEG C, is incubated 1-1.5 hour;
(5) again it is rapidly heated: be warming up to 180-210 DEG C with the speed of 40-50 DEG C/h;
(6) insulation again: be incubated 1-1.5 hour at 180-210 DEG C;
(7) fast cooling: by greenhouse cooling in carbonizing kiln to 130-140 DEG C, is incubated 0.5 hour, is then naturally cooling within 40 DEG C, last kiln discharge again.
Preferred: wherein the rapid heating condition described in step (2) is divided into three heating-up time equal heating steps: first to heat up with 55 DEG C/h, secondly heat up with 50 DEG C/h, finally heat up with 60 DEG C/h.
Preferred: wherein the fast cooling described in step (7) is the mode by passing into recirculated cooling water in coil pipe, by greenhouse cooling in carbonizing kiln to 130-140 DEG C.
The invention has the beneficial effects as follows: it is 20-28% that the decoration panel selecting thickness to be 4-5mm is dried to moisture content, is then placed in carbonizing kiln and carries out carbonization, in carbonization process, it is divided into twice intensification, in twice temperature-rise period, it is provided with again holding stage, last fast cooling, kiln discharge;Control the moisture content of decoration panel between 25-28%, ensure that the stability after decoration panel carbonization, moisture content coordinates twice intensification and incubation step, make the decoration panel made through said method, spended time is few, and thermal effectiveness is good, and mechanical property loss is minimum, good stability, not easy to crack and deformation.
Detailed description of the invention
