Abstract
The invention relates to a preparation method of uniform heat treatment wood, and in particular relates to a method for preparing the uniform heat treatment wood by stacking, aiming at solving the problems that the existing prepared heat treatment wood is not even in carbonization, obvious in wood color difference and high in cost. The method comprises the steps of: 1. selecting a wood board, and drying; 2. stacking; 3. carrying out heat treatment; and 4. cooling. The heat treatment medium needed by the method is low in cost; and the prepared heat treatment wood is balanced in carbonization inside and outside and even in wood color. The method is used for preparing the uniform heat treatment wood.
Description
Technical field
The present invention relates to the preparation method of even heat-treated wood.
Background technology
Heat-treated wood is a kind of simple physical method that adopts, and in selected medium, carries out superhigh temperature and handles, and makes its biological structure, chemical composition and key property that the Wood products of some variation take place.Its performance has colour stable, euphorosia, the biodurable height, and dimensional stability waits three outstanding characteristics well.Heat-treated wood just is subjected to the great kindness of timber and furniture industry simply deeply once appearance because of its environmental protection, technology.
But, the ThermoWood, the Retification of France, the Plato of Holland, the oil of Germany that no matter are Finland handle, or the emerging Westwood heat treatment technics of the U.S., because the way of stacking of timber board is straight stacking in the heat treatment process, the heat treatment mode of its generation is compulsory type heat treatment, easily produces the local charing inequality of timber; The heat-treatment medium that adopts is for nitrogen or for vegetable oil, all exists unfavorable factors such as environmental pollution is serious, with high costs, had a strong impact on production efficiency and the economic benefit of heat-treated wood.
Summary of the invention
The present invention will solve that charing inequality, wood color difference obviously reach the high problem of cost in the heat-treated wood table of current preparation, and a kind of method for preparing even heat-treated wood by way of stacking that provides.
A kind ofly prepare the method for even heat-treated wood by way of stacking, specifically finish according to following steps:
One, choose timber board, it is 8～13% that timber board is dried to moisture content;
Two, the timber board that step 1 is handled carries out stacking according to the horizontal vertical type way of stacking of plate face in thermal chamber, keeps the gap of 1～10cm between timber board;
Three, burning abandoned biomass material is heat-treated the thermal chamber of step 2 stack wood sheet material, is warming up to 150 ℃～240 ℃, is incubated 1～12 hour;
Four, the heat treated thermal chamber of step 3 is cooled to 30 ℃～60 ℃, takes out timber board, finish the method that way of stacking prepares even heat-treated wood.
The abandoned biomass material that the present invention uses is stalk, sawdust, straw or cotton stalk, and burning produces biological fuel gas.
The present invention is by adjusting the way of stacking of timber board in thermal chamber, makes to form a uniform temperature field in the thermal chamber, and the inside and outside charing homogeneous of the heat-treated wood that makes like this, whole wood color is even, does not have obvious aberration.The inventive method technology is simple, and is workable, efficiently solves the inside and outside charing heterogeneity of heat-treated wood of current preparation, and problems such as whole wood color significant difference have also overcome problem such as complex process, cost height in the heat-treated wood technology of preparing simultaneously.
The invention has the beneficial effects as follows: the heat-treatment medium that adopts among the present invention is biological fuel gas, and various living beings waste materials such as the discarded object during this medium can be processed by timber such as wood shavings or wood chip, the remaining stalk in crops harvesting back, herbal branch footpath are prepared.And these material sources are extensive, with low cost, use these materials to turn waste into wealth, and save earth resource, also alleviated to a certain extent the timber imbalance between supply and demand that supply falls short of demand, protected timber resources.The medium of the biological fuel gas that uses the preparation of these living beings waste materials simultaneously during as timber heat treatment, with low cost, reduce the high problem of current all heat-treated wood costs greatly, for promoting and science and technology research and development heat-treated wood provides new approach and thinking.
The present invention is for the preparation of even heat-treated wood.
