Abstract
The invention discloses a timber high-temperature treatment method. The timber high-temperature treatment method comprises the following steps of 1, stacking timbers so that gaps for allowing gas flow passing are formed around each one of the timbers, 2, fixing positions of the stacked timbers to prevent timber displacement caused by gas passing, 3, putting the stacked timbers in saturated steam flows having a temperature of 85-90 DEG C for 14-16h, 4, putting the stacked timbers in dry gas flows having a temperature of 130-135 DEG C for drying, 5, putting the stacked timbers in the saturated steam flows having a temperature of 140-145 DEG C for 2-3h, and 6, putting the stacked timbers in the dry gas flows having a room temperature and carrying out drying and cooling. The timbers treated by the timber high-temperature treatment method have preservative effects the same as that of chemically-treated timbers. The timber high-temperature treatment method is free of chemical products and is conducive to environmental protection.
Description
Technical field
The present invention relates to the high-temperature processing method of timber.
Background technology
Original timber all can, through certain processing to increase its antiseptic property, improve durability.Traditional antiseptic mode is to adopt chemical treatment, is about to timber and is immersed in chemicals, by chemicals, the infiltration of timber is realized to the preservation of timber against decay and processes.But along with the lifting of environmental consciousness, chemicals does not more and more wish to be used because it has toxicity.As a kind of of chemical treatment mode, substitute, the heat treatment mode recently rising also can play corrosion-resistant effect effectively.Heat treated can be so that timber dimensionally stable, and timber is dry to promote the useful life longevity of timber.According to type divide, timber can be divided into hardwood and cork, and wherein hardwood is mainly worth broadleaf tree, and cork mainly refers to conifer trees.Hardwood, because inside exists conduit, is therefore difficult to heat-treat than cork more.
Summary of the invention
The object of the present invention is to provide a kind of high-temperature processing method of timber, the timber of processing can reach the antiseptic effect same with process chemical treatment, avoids using chemicals, is conducive to environmental protection.
For achieving the above object, technical scheme of the present invention is the high-temperature processing method of a kind of timber of design, comprises the steps:
Stacking timber, the surrounding of each timber all has the gap that air feed stream passes through;
Fixing through the position of stacking timber, stop timber air-flow by time be subjected to displacement;
The saturated steam flowing that timber through stacking is placed in to 85～90 ° of C reaches 14～16 hours;
The dry gas stream that timber through stacking is placed in to 130～135 ° of C is dried;
The saturated steam flowing that timber through stacking is placed in to 140～145 ° of C reaches 2～3 hours;
The dry gas stream that timber through stacking is placed in to room temperature is dried with cooling.
Advantage of the present invention and beneficial effect are: a kind of high-temperature processing method of timber is provided, and the timber of processing can reach the antiseptic effect same with process chemical treatment, avoids using chemicals, is conducive to environmental protection.
The specific embodiment
Below in conjunction with embodiment, the specific embodiment of the present invention is further described.Following examples are only for technical scheme of the present invention is more clearly described, and can not limit the scope of the invention with this.
The concrete technical scheme of implementing of the present invention is:
