Description

METHOD OF MANUFACTURING CHAMAECYPARIS OBTUSA COMPRESSION INPREGNATING WOOD}

The present invention relates to a method of manufacturing a cypress compressed hardwood, and more particularly, to a method of manufacturing a cypress compressed hardwood that can maximize the strength by thermally compressing dried cypress.

In general, cypress is a tree that emits the most phytoncide and is recognized as an eco-friendly material, but unlike other materials, it has a low strength compared to its weight.

Cypress is a cultural material that is easy to process such as cutting and bonding, and has insulation, sound absorption, and heat insulation in electricity, sound, heat, etc., and is friendly to people with friendly colors and patterns. to be.

Despite the advantages of wood, wood is sensitive to moisture, exposed to hygroscopic environment, shrinkage and swelling, its dimensions change, and its strength is not free from dimensional stability, so its use is limited. Cypress also has the following problems.

First, cypress products often have warpage or warpage due to their frequent contact with external shocks, which can lead to harmful environments in cracked or cracked products.

Second, there is a problem that the hardness of the surface of the wood is very low during use of the product, the surface is easily damaged, the surface is rough, and the softness occurs.

First, the cypress 100 is processed into a thin plate form having a predetermined thickness. (S100)

As a specific method of processing the cypress 100 in a thin plate shape having a predetermined thickness, a method of cutting the cypress 100 thinly in the longitudinal direction or in the width direction (for example, length 2,400 mm, width 100 mm cut) ) Can be adopted.

And, as shown in Figure 4 (a) it is possible to cut the thickness of the cypress 100 to 12mm (12T) ~ 13mm (13T).

At this time, the specific method for processing the cypress 100 into a thin plate shape having a predetermined thickness, so various general methods are already widely used and will not be described in detail.

In addition, the cypress 100 may be processed into a thin plate form, but the shape and thickness to be processed may be processed into different shapes and thicknesses according to various purposes such as luba, molding, and flooring.

Thereafter, the cypress 100 processed in the form of a thin plate is dried in a natural state for a certain period of time. (S200)

Referring to the process of naturally drying the cypress 100, the dried cypress 100 processed to a certain thickness in a natural state to dry, but in the summer season to dry for 2 months to 3 months, in winter 5 months ~ Allow to dry over six months.

In other words, in order to lower the moisture content of the cypress 100, the summer is dried for a shorter period of time than in winter when the outside temperature is high.

As such, when the cypress 100 is naturally dried for 2 months to 3 months in the summer, the moisture content is 40% to 45%, and the moisture content is 45% to 50 when the natural drying is performed for 5 months to 6 months in the winter. Will be%.

Thereafter, the naturally dried cypress 100 is put into a heat roller compression-enhanced veneer 200 to be thermally compressed to increase the compressive strength (S300).

As shown in Figures 2 to 3, the heat roller compression reinforcement veneer 200 is a main body 210 having a support plate 211 to which the cypress 100 is raised and transported, and the main body 210 of The roller 220 is heated by the supply of electricity to the upper portion to compress the cypress 100, and the motor 230 for rotating the roller 220 on the side of the roller 220.

Heat is uniformly transferred to the roller 220 of the heat roller compression-enhanced veneer 200 when the dried cypress 100 is put into the heat roller compression-enhanced veneer 200 to heat the cypress 100 Cyclone wood (100) on the heat roller compression hardening plate (200) while preheating the roller 220 for 40 to 50 minutes after operating the hot roller compression hardening plate (200) so that the entire surface of the evenly compressed ) And heat compressed.

After operating the thermal roller compression reinforcement plate 200 in the state of pre-heating the cypress 100 in the state of preheating the roller 220 for 1 to 10 minutes of the thermal roller compression reinforcement plate 200 A faintly red line is formed on the roller 220, and the mold of the cypress middle middle is not imprinted.

In addition, when the heat roller compression reinforcing plate 200 is operated and heat-compresses the cypress 100 in a state in which the roller 220 is preheated for 10 minutes to 20 minutes, the roller 220 is directly burned. Soot is generated where abuts, soot is cut out on the cypress 100.

In addition, after operating the thermal roller compression-enhanced board 200, if the heat treatment of the cypress 100 in the state of preheating the roller 220 for 20 minutes to 30 minutes soot occurs in the entire roller 220 In order to prevent soot from being photographed on the cypress 100, the cypress 100 is put into the test after about two times.

In addition, the roller 220 is gradually reddish when the cypress 100 is thermally compressed in a state in which the roller 220 is preheated for 30 minutes to 40 minutes after the thermal roller compression hardening plate 200 is operated. As a result of putting the cypress 100 while turning, removing soot will start to show the color of the carbonized wood as a whole.

That is, when the preheating time of the roller 220 is 50 minutes after the operation of the thermal roller compression-enhanced veneer 200, when the dried cypress 100 is thermally compressed, uniform heat is transmitted to the roller 220. Not because the cypress 100 is not evenly compressed, the quality of the product is degraded.

On the other hand, as shown in Figure 2 by installing the conveying conveyor 300 on the side of the heat roller compression reinforced laminate 200 to heat the dried cypress 100 using the heat roller compressed reinforced plate 200 When compressing, it is possible to transfer the cypress 100 to the support plate 211 of the heat roller compression reinforced veneer 200 by the conveying conveyor (300).

In addition, the cypress 100, which is thermally compressed by the heat roller compression-enhanced veneer 200, is, for example, 12 mm (12T) of FIG. 2 before being compressed as shown in FIG. As shown in (b), it is thinned to 11 mm (11T), but due to thermal compression, the compressive strength is stronger than conventional products as shown in Table 1 below.

(AR) Reinforced Molding
(BM) Hardened Luba
(BR) Compressive strength 42.5N / ㎡ 41.4N / ㎡ 45.8N / ㎡ 48.3N / ㎡

As can be seen in the test report of Table 1 and FIG.

In addition, when the dried cypress 100 is put into a heat roller compression-enhanced veneer 200 and thermally compressed, the moisture content is lowered to 15% to 20%, and the swelling rate is lowered to 30% to 35%.

Subsequently, when the dried cypress 100 is manufactured by thermally compressing the dried cypress 100 into the heat roller compression-enhanced veneer 200, the surface is processed to be smoothly processed or a pattern may be formed using a molder. (S400)

Cypress wood of the present invention manufactured as described above is a cypress wood, which is dried by varying the period according to the summer and winter different environmental conditions such as outside temperature and humidity in the natural state of the cypress 100 processed to a predetermined thickness The water content of (100) can be kept constant.

Then, by operating the hot roller compression reinforced plate 200 to support the dried cypress 100 in a state in which the roller 220 is preheated for a predetermined time (40 minutes to 50 minutes) the support plate 211 and the roller ( The heat is compressed by the heat and compressive force generated by the roller 220 while passing between the 220.

In addition, by manufacturing the cypress 100 dried by the heat roller compression-enhanced veneer 200 through thermal compression and heat treatment, the dimensions of the cypress 100 can be stabilized and the compressive strength can be increased.

Therefore, the cypress 100 processed to a predetermined thickness is naturally dried and heat-compressed by heat and compression of the roller 220, thereby reducing the thickness of the cypress hardened wood and improving the compressive strength to maximize the quality of the product. It becomes possible.

As described above, the present invention is not limited to the above-described specific preferred embodiments, and any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims can be various. Modifications are possible, of course, and such changes are within the scope of the claims.
