Abstract
The invention discloses a high temperature processing method for wood. The high temperature processing method comprises the following steps: stacking wood in such a manner that gaps through which airflow can pass are formed between the stacked wood and adjacent wood; fixing the position of the stacked wood, so as to avoid displacement of the wood when airflow passes through the gaps; placing the stacked wood in saturated vapor stream at a first temperature for a first time; placing the stacked wood in dry airflow at a second temperature for drying; placing the stacked wood in saturated vapor stream at a third temperature for a second time; and placing the stacked wood in dry airflow at room temperature for drying and cooling. The high temperature processing method is suitable for hardwood heat processing; and wood processed according to the high temperature processing method can perform the same anti-corrosion effect as that processed by a method in which wood is processed in a chemical manner, while the use of chemicals is avoided, which is beneficial to environmental protection.
Description
Technical field
The present invention relates to the timber treatment technology field, relate in particular to a kind of high-temperature processing method of timber.
Background technology
Timber products so original timber all can pass through certain processing to increase its antiseptic property, improves durability owing to receive easily corrosion.Timber in particular for furniture, base plate needs preservative treatment more.
Traditional antiseptic mode is to adopt chemical treatment, is about to timber and is immersed in the chemicals, by chemicals the infiltration of timber is realized that the preservation of timber against decay processes.But along with the lifting of environmental consciousness, chemicals has toxicity owing to it and does not more and more wish to be used.Substitute as a kind of of chemical treatment mode, the heat treatment mode that recently rises also can play the corrosion-resistant effect effectively.Heat treated can be so that the timber dimensionally stable, and with the timber drying to promote the useful life longevity of timber.
According to type divide, timber can be divided into hardwood and cork, and wherein hardwood mainly is worth broadleaf tree, the main pointer leaf of cork trees.Therefore hardwood be difficult to heat-treat than cork because there is conduit in inside more.
Summary of the invention
The present invention is intended to propose a kind of heat treatment method that hardwood is processed of being suitable for.
According to one embodiment of the invention, a kind of high-temperature processing method of timber is proposed, comprise following step:
Stacking timber has the gap that air feed stream passes through between stacking timber and adjacent timber;
Fixing through the position of stacking timber, stop timber air-flow by the time be subjected to displacement;
To place the saturated steam flowing of the first temperature to reach the very first time through stacking timber;
To place the dry gas stream of the second temperature to carry out drying through stacking timber;
To place through stacking timber the saturated steam flowing of the 3rd temperature to reach for the second time;
To place the dry gas stream of room temperature to carry out drying and cooling through stacking timber.
In one embodiment, each timber around all have a gap.
In one embodiment, the first temperature is 95 ° of C～100 ° C.The very first time is 8～10 hours.
In one embodiment, the second temperature is 120 ° of C～125 ° C.
In one embodiment, the 3rd temperature is 130 ° of C～140 ° C.The second time was 4～6 hours.
The high-temperature processing method of timber of the present invention is applicable to hardwood is heat-treated, and the timber of processing according to high-temperature processing method of the present invention can reach the antiseptic effect same with the process chemical treatment, but can avoid using chemicals, is conducive to environmental protection.
Description of drawings
Fig. 1 has disclosed the flow chart according to the compression treatment process of the ligneous piece of one embodiment of the invention.
The specific embodiment
With reference to shown in Figure 1, disclosed the flow chart according to the high-temperature processing method of the timber of one embodiment of the invention, this high-temperature processing method 100 comprises following step:
102. stacking timber has the gap that air feed stream passes through between stacking timber and adjacent timber.For so that each timber can both obtain sufficient heat treatment, in one embodiment, all has the gap around each timber.The timber that namely is positioned at the bottom also can be high by appropriate frame, so that the gap that air feed stream passes through can be vacated in the bottom of timber.
104. fixing through the position of stacking timber, stop timber air-flow by the time be subjected to displacement.According to processing method of the present invention, timber can be placed in swiftly flowing air-flow or the vapor stream, therefore stacking timber is needed be fixed so that air-flow or vapor stream not can so that timber be shifted.
106. will place the saturated steam flowing of the first temperature to reach the very first time through stacking timber.In one embodiment, the first temperature is 95 ° of C～100 ° C, and the very first time is 8～10 hours.Namely in can being placed on the saturated steam flowing of 95 ° of C～100 ° C, keeps in stacking timber 8～10 hours time.
108. will place the dry gas stream of the second temperature to carry out drying through stacking timber.In one embodiment, the second temperature is 120 ° of C～125 ° C.In step 108, timber carries out high temperature drying, uses the high temperature gas flow of 120 ℃～125 ° of C to carrying out drying through stacking timber.The relative humidity of the high temperature gas flow of Dryly use is about 5%, and the normative reference that drying is finished is that the relative humidity of the air-flow that flows out from stacking timber reaches 5% or lower.
110. will place through stacking timber the saturated steam flowing of the 3rd temperature to reach for the second time.In one embodiment, the 3rd temperature is 130 ° of C～140 ° C, and the second time was 4～6 hours.After having carried out high-temperature steam processing and high temperature drying first, timber is carried out secondary high-temperature steam processing in step 110, and secondary high-temperature steam is processed the vapor (steam) temperature that the vapor (steam) temperature of using is higher than for the first time high-temperature steam processing.Because timber is maintained under the high temperature in the process of high temperature drying, therefore be under the high temperature all the time from step 106～step 110 timber.
112. will place the dry gas stream of room temperature to carry out drying and cooling through stacking timber.In step 112, timber carries out drying and cooling by the dry gas stream that is in room temperature.The relative humidity of dry gas stream is about 5%.A normative reference dry and that cooling is finished is that the relative humidity of the air-flow that flows out from stacking timber reaches 5% or lower, and temperature reaches room temperature.
The high-temperature processing method of timber of the present invention is applicable to hardwood is heat-treated, and the timber of processing according to high-temperature processing method of the present invention can reach the antiseptic effect same with the process chemical treatment, but can avoid using chemicals, is conducive to environmental protection.
