Abstract
The invention discloses a timber thermal treatment method, which is characterized by comprising the following steps: 1) coating wood chip on the timber surface; B, stacking the timber coated by wood chip in a carbonization kiln; C, closing a kiln door, slowly heating to the temperature of 75 DEG C, keeping the temperature until the timber is dried; D, rapidly heating the kiln to the temperature of 150 DEG C, keeping the temperature until the coated wood chip layer is completely carbonized and blackened; E, stopping the heating, naturally cooling the kiln at the temperature of below 40 DEG C, removing the timber and then warehousing. The invention provides a thermal treatment method which is easy to control, the method enables uniform carbonization on the timber for reaching the effects of anticorrosion, insect resistance and deformation resistance of the timber.
Description
Technical field
The present invention relates to a kind of Wood treatment method, particularly a kind of heat treatment method to timber.
Background technology
Wood raw material is because the moisture content problem, and is perishable, be prone to go mouldy, be subject to insect pest, be prone to deformation.Timber is carried out carbonization then can avoid the problems referred to above to a certain extent.For this reason, some can directly carry out surperficial carbonization with naked light to timber, but this carbonization lack of homogeneity; Also some utilizes carbide furnace that timber is carried out carbonization, but because carbonizing degree is difficult to control, is easy to make timber lose mechanical strength because of undue carbonization, can not be as processing raw material.
Summary of the invention
The objective of the invention is: a kind of Wood heat treatment method is provided.The invention provides a kind of heat treatment method that is easy to control, can carry out even carbonization, to reach wood preservation, insect protected, distortion-free effect timber.
The object of the invention can be realized through following technical proposal: a kind of Wood heat treatment method is characterized in that it may further comprise the steps:
A, apply wood chip at wood surface;
B, the timber that will scribble wood chip are stacked in the carbonization kiln;
C, close wicket, slowly be warming up to 75 ℃, keep temperature, until timber stoving;
D, heat up kiln temperature to 150 ℃ rapidly keep temperature, until the whole carbonizations blackout of the wood chip layer that applies;
E, stop heat supply, when naturally cooling to below 40 ℃ in the kiln, the timber kiln discharge is put in storage.
In the aforesaid Wood heat treatment method, in the A step, wood chip being coated in the method for wood surface, is after wood surface is smeared natural adhesive, with the form of spraying wood chip is pasted wood surface.
In the aforesaid Wood heat treatment method, said natural adhesive is a gelatinized corn starch.
Compared with prior art, the present invention forms carbonization buffer layer through applying wood chip at wood surface, makes timber when carrying out carbonization treatment, be difficult for undue carbonization, and the carbonization effect is more even, and wood chip also can be used as observes the indicator whether carbonization is accomplished.And what apply that wood chip uses is the such natural adhesive of gelatinized corn starch, because gelatinized corn starch mainly is a carbohydrate, therefore in stove, also will not only can produce pernicious gas with wood chip carbonization together during heating, but also increase the cushioning effect to the wood chip carbonization.Method of the present invention only needs to observe the carbonization situation that the wood chip color just can intuitively be understood inner timber, and is therefore clearer and more definite to the control of carbonizing degree, simpler, need not in carbonisation timber carried out complicated procedures of forming such as sample detecting.Method of the present invention can make moisture content drop to the half the or lower of common drying means.
The specific embodiment
A kind of Wood heat treatment method:
1, after wood surface is smeared gelatinized corn starch, wood chip is pasted wood surface with the form of spraying;
The timber that 2, will scribble wood chip is stacked in the carbonization kiln;
3, close wicket, slowly be warming up to 75 ℃, keep temperature, until timber stoving (moisture content is near common drying means);
4, heat up rapidly kiln temperature to 150 ℃ keeps temperature, until the whole carbonizations blackout of the wood chip layer that applies (moisture content drops to below half the in the step 3).
5, stop heat supply, when naturally cooling to below 40 ℃ in the kiln, the timber kiln discharge is put in storage.During warehouse-in, weightlessness 2%～10% when timber advances kiln.
Claims (3)
1. Wood heat treatment method is characterized in that it may further comprise the steps:
A, apply wood chip at wood surface;
B, the timber that will scribble wood chip are stacked in the carbonization kiln;
C, close wicket, slowly be warming up to 75 ℃, keep temperature, until timber stoving;
D, heat up kiln temperature to 150 ℃ rapidly keep temperature, until the whole carbonizations blackout of the wood chip layer that applies;
E, stop heat supply, when naturally cooling to below 40 ℃ in the kiln, the timber kiln discharge is put in storage.
2. Wood heat treatment method according to claim 1 is characterized in that: in the A step, wood chip being coated in the method for wood surface, is after wood surface is smeared natural adhesive, with the form of spraying wood chip is pasted wood surface.
