The present invention mainly provides a kind of method of processing wooden piece of trees in Palmaceae, please cooperate referring to Fig. 1, Fig. 2, and by seeing among the figure, method of the present invention mainly includes:
Capture one section palm trunk: one section trunk of acquisition on trees in Palmaceae;
Cut into square: it is square that the trunk that is captured is cut into the cross section;
Moisture content is got rid of in pressurization: be arranged in around the square trunk with pressing plate, and promote pressing plate with cylinder pressure trunk is pressurizeed, and can be expelled to the moisture content in the trunk below the certain percentage apace, as drop to 30% to 50%, wherein, promptly get rid of 60% moisture content, when moisture content is got rid of in pressurization to trunk to drop to 40% for preferable, be to be arranged in around the trunk, and come trunk is pressurizeed with the synchronous or asynchronous promotion pressing plate of cylinder pressure with pressing plate;
Oven dry: the trunk after will pressurizeing is dried, and the interior residual moisture content of trunk is reduced to below the certain percentage, as drop to 6% to 8%;
Vacuum glue pouring: the trunk after will drying is placed in the mould, utilize the technology of vacuum glue pouring that colloid is injected trunk again, make colloid fill in the gap between each cellulosic in trunk, wherein colloid can be urea glue, latex or resin etc., and the flow process of vacuum glue pouring can be referring to as shown in Figure 3, it can be inserted trunk in one mould, opening air-extractor earlier will extract out in the air in the mould, make mould present vacuum state, after closing air-extractor, colloid is injected mould through a pipeline then, colloid is filled in the genuine mould, and fill in gap between each cellulosic in the trunk, a period of time to be left standstill goes out mould with unnecessary colloid by another tubes rows after allowing colloid fully inject in the trunk again, finishes the operation of vacuum glue pouring;
Pressurize: after the trunk behind the encapsulating is taken out in mould, cooperate with pressing plate and cylinder pressure again the trunk behind the encapsulating is pressurizeed, unnecessary colloid is flowed out, and allow the trunk behind the encapsulating have the suitable degree of packing, the colloid that is flowed out simultaneously also can reclaim use once again, can reduce whole processing cost, in addition when unnecessary colloid is got rid of in pressurization to trunk, be to be arranged in around the trunk, and come trunk is pressurizeed with the synchronous or asynchronous promotion pressing plate of cylinder pressure with pressing plate;
Pressurization is dry: dry trunk under the state of pressurization, make the colloid drying in the trunk, produce the situation of dilatancy in the time of so can avoiding trunk because of the colloid drying, to keep the good shape of trunk, and the structural strength of the raising timber that forms, and when trunk pressurizeed, insert again in another mould after can earlier the trunk of getting rid of unnecessary colloid after pressurizeing being taken out in original mould, perhaps can also original mould trunk be carried out the step of pressing and stoving;
Stripping forming: the trunk after will drying takes out in mould, and make the trunk behind the encapsulating constitute a wooden material, so just can allow the trunk behind the encapsulating provide the good degree of packing and support force, and the timber that can be used as furniture, building materials or decoration usefulness use because of dried colloid.
By above-mentioned processing method; can allow general palmaceous trees after processing, use as timber; except that the effective utilization and economic worth that can significantly improve trees in Palmaceae; also can avoid trees in Palmaceae formation waste material and cause the waste of resource and the pollution of environment; it is quite little to the influence of ecology that next cuts stroke trees in Palmaceae, also can guarantee the Sustainable Development of environmental ecology.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, though the present invention discloses as above with preferred embodiment, yet be not in order to limit the present invention, any those skilled in the art, in the scope that does not break away from technical solution of the present invention, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be not break away from the technical solution of the present invention content, foundation technical spirit of the present invention is to above any simple modification that embodiment did, equivalent variations and modification all still belong in the scope of technical solution of the present invention.
