Abstract
Prepared a method for uniform heat treatment wood by way of stacking, the present invention relates to the preparation method of uniform heat treatment wood.The present invention will solve the problem that in the heat-treated wood table of current preparation, charing is uneven, wood color difference is obvious and cost is high.Method: one, choose timber board, dry; Two, stacking; Three, heat treatment; Four, lower the temperature.Heat-treatment medium required for the present invention is with low cost, and in obtained heat-treated wood table, charing is balanced, and wood color is even.The present invention is for the preparation of uniform heat treatment wood.
Description
Technical field
The present invention relates to the preparation method of uniform heat treatment wood.
Background technology
Heat-treated wood a kind ofly adopts simple physical method, in selected medium, carries out superhigh temperature process, makes its biological structure, chemical composition and key property that the Wood products of some change occur.Its performance has colour stable, euphorosia, and biodurable is high, the feature that good stability of the dimension etc. three are outstanding.Heat-treated wood once appearance, just because its environmental protection, technique are simply deeply by the great kindness of timber and furniture industry.
But, no matter be the ThermoWood of Finland, Retification, the Plato of Holland, the German oil quality treatment of France, or the Westwood heat treatment technics that the U.S. is emerging, because in heat treatment process, the way of stacking of timber board is straight stacking, its heat treatment mode produced is compulsory type heat treatment, easily produces timber local and carbonizes inequality; The heat-treatment medium adopted, for nitrogen or for vegetable oil, all also exists the unfavorable factors such as environmental pollution is serious, with high costs, has had a strong impact on production efficiency and the economic benefit of heat-treated wood.
Summary of the invention
The present invention will solve the problem that in the heat-treated wood table of current preparation, charing is uneven, wood color difference is obvious and cost is high, and a kind of method being prepared uniform heat treatment wood by way of stacking provided.
Prepared a method for uniform heat treatment wood by way of stacking, specifically complete according to following steps:
One, choose timber board, timber board being dried to moisture content is 8 ~ 13%;
Two, timber board step one processed carries out stacking according to the horizontal vertical type way of stacking in plate face in thermal chamber, retains the gap of 1 ~ 10cm between timber board;
Three, burn waste biomass material, heat-treated by the thermal chamber of step 2 stack wood sheet material, be warming up to 150 DEG C ~ 240 DEG C, be incubated 1 ~ 12 hour;
Four, heat treated for step 3 thermal chamber is cooled to 30 DEG C ~ 60 DEG C, takes out timber board, complete the method that way of stacking prepares uniform heat treatment wood.
The waste 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 the way of stacking of adjustment timber board in thermal chamber, and make to form a uniform temperature field in thermal chamber, the inside and outside charing of heat-treated wood obtained is like this homogeneous, and overall wood color is even, without obvious aberration.The inventive method technique is simple, workable, and efficiently solve the heat-treated wood inside and outside charing heterogeneity of current preparation, the problems such as overall wood color significant difference, also overcome complex process in heat-treated wood technology of preparing, high in cost of production problem simultaneously.
The invention has the beneficial effects as follows: the heat-treatment medium adopted in the present invention is biological fuel gas, this medium can be processed by timber in discarded object as after wood shavings or wood chip, crops harvesting prepared by the various biomass waste material such as remaining stalk, herbal branch footpath.And these material sources are extensive, with low cost, use these materials to turn waste into wealth, save earth resource, also alleviate to a certain extent the timber imbalance between supply and demand that supply falls short of demand, protect timber resources.The biological fuel gas simultaneously using these biomass waste material to prepare is as medium during heat_treated wood, with low cost, greatly reduces the problem that current all heat-treated wood costs are high, provides new approach and thinking for promoting with science and technology research and development heat-treated wood.
The present invention is for the preparation of uniform heat treatment wood.
