Description
본 발명은 오일을 이용한 목재의 급속 건조 방법에 관한 것으로 보다 상세하게는 채벌된 원목 또는 각재된 목재를 오일로 처리하여, 수분을 제거함과 동시에 목질을 단단하게 함으로써, 가공상 목재료의 품질을 고품질로 향상시킬 수 있는 새로운 방법에 관한 것이다.The present invention relates to a method for rapidly drying wood using oil, and more particularly, by treating the collected wood or the lumber with oil, thereby removing moisture and hardening the wood, thereby improving the quality of the wood material for processing. It is about a new way to improve.
일반적으로 자연상태에서 벌목된 나무를 가공함에 있어서는 목질 내부에 함유된 수분을 최대한 제거하여 수분 함유율를 낮추어야만이 가공 목재 제품의 균열, 비틀림 등 변형의 요소를 제거할 수 있게 된다. In general, in processing wood felled in the natural state, the moisture content in the wood should be removed as much as possible to reduce the moisture content, so that the elements of deformation, such as cracking and torsion of processed wood products, can be removed.
종래의 목재 가공방법 중에는 크게 열풍 건조와 왁스에 의한 탈수건조 방법등이 있다. Conventional wood processing methods include hot air drying and a dehydration drying method using wax.
이중 열풍건조는 크게 벌목된 나무를 자연건조, 인공건조 등 열과 바람을 수단으로 수분 함유율을 감소시키는 방법으로 이들 방법은 건조 시간이 많이 걸리므로 목재제품의 생산 코스트를 높이는 원인이 되고 있으며, 건조된 후에도 다시 외부 조건에 의해 수분이 재흡수되는 요요현상을 나타내는 문제점을 가지고 있다.Hot air drying is a method of reducing the moisture content of largely felled wood by means of heat and wind, such as natural drying and artificial drying. These methods take a long time to dry, which increases the production cost of wood products. Even after that, there is a problem in that the yo-yo phenomenon of re-absorption of moisture by external conditions occurs.
한편, 파라핀 왁스의 탈수 건조법은 가열 용융된 파라핀 왁스 용액에 원목 또는 목재를 침지하고 가열하여 간단히 건조하는 것으로 알려져 있는데, 파라핀왁스의 발수성에 의한 내후성이 목재에 부여되고, 건조후의 목재표면은 건조과정에서 수반되어 발생하는 수증기와 함께 용출되는 목재의 추출성분에 의하여 연한 갈색으로 되는데, 파라핀 왁스의 피막이 코팅되어 목재에 수분이 재흡수되지 않는 장점이 있다.On the other hand, the dehydration drying method of paraffin wax is known to simply dry by immersing wood or wood in a heat-melted paraffin wax solution and heating it. It is light brown due to the extraction component of wood eluted with water vapor generated in conjunction with, the coating of paraffin wax has the advantage that the wood is not reabsorbed moisture.
그러나, 왁스 건조법은 사용된 왁스는 용탈된 수분을 함유함으로써, 왁스가 폐기물화되거나, 재 사용하기 위해선 정제를 위한 추가비용이 부담되는 문제점이 있다.However, the wax drying method has a problem in that the wax used contains the eluted moisture, so that the wax becomes waste or additional costs for refining to be reused.
이에, 본 출원인은 채벌된 나무를 장기간 건조시키는 재래식 과정을 거치지 않고, 목질의 섬유조직이 파괴되지 않고 규칙적인 수축현상을 일으켜 강도를 높이고, 건조과정을 거치면서, 목질변형으로 인한 목재자원의 낭비나 제품의 하자 발생 등의 문제점을 해결할 수 있는 방법을 찾고자 하였다. Accordingly, the present applicant does not go through the conventional process of drying the harvested wood for a long time, the wood fiber tissue is not destroyed, causing a regular contraction phenomenon to increase the strength, drying process, waste of wood resources due to wood deformation Or to find a way to solve problems such as product defects.
이에, 본 출원인은 건성유의 내수적(耐水的) 성질을 이용하면, 목재의 수분을 신속하게 제거하는 동시에 목재의 강도를 높이고, 나무결도 선명하게 나타나고, 수분의 흡수를 억제하는 오일막이 목재 표면에 형성되는 것을 확인하였으며, 이와 더불어 사용된 오일은 재사용할 수 있는 사실을 확인하여, 본 발명을 완성하였다.Accordingly, the present applicant uses the water-resistant property of the dry oil, which quickly removes water from the wood, increases the strength of the wood, provides a clear grain of wood, and an oil film on the surface of the wood that suppresses the absorption of water. It was confirmed that it is formed, and the oil used in addition to the fact that it can be reused, to complete the present invention.
본 발명은 상기한 바와 같은 종래 기술의 문제점을 인식하여, 개선하기 위해 안출된 것으로, 목재의 수분은 신속히 제거하면서도 품질이 우수한 목재의 건조 방법을 제공하는 것을 목적으로 한다.The present invention has been made to recognize and improve the problems of the prior art as described above, and an object of the present invention is to provide a method for drying wood with excellent quality while removing moisture of wood quickly.
상기한 목적을 달성하기 위하여, 본 발명의 오일을 이용한 목재의 건조방법은 오일을 산화 및 숙성하는 단계(S1)와, 산화 및 숙성된 오일을 가열하는 단계(S2)와, 가열된 오일을 목재가 투입된 목재 가공 탱크에 충진하는 단계(S3)와, 목재 가공 탱크를 가열하는 단계(S4)와, 목재와 오일을 반응시키는 단계(S5)와, 목재 가공 탱크로부터 목재를 인출하는 단계(S6), 및 보관 단계(S7)로 이루어져 있다.In order to achieve the above object, the drying method of the wood using the oil of the present invention comprises the step of oxidizing and aging the oil (S1), the step of heating the oxidized and aged oil (S2), and the heated oil wood Filling step (S3), the step of heating the wood processing tank (S4), the step of reacting the wood and oil (S5), and withdrawing the wood from the wood processing tank (S6) , And storage step (S7).
본 발명은 바람직하게는 도 3에서 도시한 바와 같이, 우선, 오일은 목재와 반응시키기 전에 폭기를 하면서 산화를 촉진 시키고 오일탱크에 저장하는 과정을 거치는 오일을 산화 및 숙성하는 단계(S1)와, 상기 단계(S1)를 거친 가공 오일은 목재와 반응하여 목재 내 수분을 가장 효율적으로 제거할 수 있도록 온도를 미리 120 내지 150℃로 맞추기 위해 산화 및 숙성된 오일을 가열하는 단계(S2)와, 오일을 원목이나 각재된 목재와 반응시키기 위해, 상기 단계(S2)를 거친 가열된 오일을 목재가 투입된 목재 가공 탱크에 이송하는 가열된 오일을 목재가 투입된 목재 가공 탱크에 충진하는 단계(S3)와, 오일과 목재의 반응 온도가 120 내지 150℃로 유지하기 위해서, 목재 가공 탱크를 가열하는 단계(S4)와, 목재가 함유하고 있는 수분의 대부분을 제거하기 위해서, 120 내지 150℃에서 8 내지 72시간 동안 목재와 오일을 반응시키는 단계(S5)와, 상기 단계(S5)를 거친 후, 목재 가공 탱크로부터 목재를 인출하는 단계(S6), 및 보관 단계(S7)로 이루어진다.Preferably, the present invention, as shown in Figure 3, the first step of oxidizing and aging the oil undergoing a process of promoting oxidation and storage in the oil tank while aeration while reacting the oil with wood, Processed oil passed through the step (S1) is reacted with the wood to heat the oxidized and aged oil in advance to adjust the temperature to 120 to 150 ℃ in advance so as to remove the water in the wood most efficiently (S2) and the oil In order to react with the wood or lumber timber, the step (S3) of filling the heated oil to the wood processing tank to the wood and the heated oil passed through the step (S2) to the wood processing tank into the wood, In order to maintain the reaction temperature of the oil and wood at 120 to 150 ℃, the step of heating the wood processing tank (S4), and in order to remove most of the water contained in the wood, within 120 Reacting wood and oil at 150 ° C. for 8 to 72 hours (S5), after passing the step (S5), withdrawing the wood from the wood processing tank (S6), and storage step (S7) .
이하, 본 발명을 보다 상세히 설명하자면 다음과 같다.Hereinafter, the present invention will be described in more detail.
일반적으로 오일은 상온(常溫)에서는 액체로서 점성(粘性)이 있고, 가연성(可燃性)이며 물에 용해되지 않고 물보다 가벼워서 수면 위에 엷은 층을 이루어 퍼지는 물질을 말하는데, 주로 올레산, 리놀산, 리놀렌산 등 주로 불포화지방산으로 구성되어 있기 때문에 상온에서 액체인 상태로 있다. In general, oil refers to a substance that is viscous, flammable, insoluble in water, lighter than water, and spreads in a thin layer on the surface of water at room temperature. Since it is mainly composed of unsaturated fatty acids, it is in a liquid state at room temperature.
어유(魚油)와 같은 동물성 오일은 악취를 풍기나, 니켈과 같은 촉매를 써서 수소를 첨가하여 경화유(硬化油)를 사용하기도 한다. Animal oils, such as fish oil, may smell bad, or hydrogenated oils may be used by adding hydrogen using a catalyst such as nickel.
식물성 오일은 불포화도에 따라 아마인유(亞麻仁油), 동유(桐油), 대마유(大麻油) 등의 건성유(乾性油)와, 콩기름, 참기름, 유채유 등의 반건성유 및 피마자유, 올리브유 등의 불건성유로 분류된다Vegetable oils are dried oils such as linseed oil, kerosene oil, and hemp oil, and semi-dry oils such as soybean oil, sesame oil, and rapeseed oil depending on the degree of unsaturation. Classified as dry oil
한편, 본 발명에 사용되는 오일은 상기 식물성 오일 중 건성유이면 물리, 화학적으로 모두 가능하나, 생산 비용면에서 아마인유를 사용하는 것이 바람직하다.On the other hand, the oil used in the present invention may be both physically and chemically as long as it is a dry oil of the vegetable oil, but it is preferable to use linseed oil in terms of production cost.
아마인유는 아마의 씨에 함유되어 있는 건성 지방유(脂肪油)로, 생아마인유는 비중 0.932∼0.936, 굴절률 1.480∼1.483, 응고점 －18∼－27℃로, 리놀레산과 리놀렌산 등의 불포화산(不飽和酸)을 다량으로 함유하기 때문에 불포화성이 풍부하며, 요오드값이 175∼195로 건성유(乾性油)에 해당한다. 지방산의 구성비는 포화산이 8∼9%, 올레산이 10∼15%, 리놀레산이 25∼35%, 리놀렌산이 35∼45%, 산소산 이 6.5% , 비(非)비누화물이 0.5∼1.5% 및 글리세롤기(基)가 4.5% 등으로 되어있다.Flaxseed oil is a dry fatty oil contained in the seeds of flax, raw flaxseed oil has a specific gravity of 0.932 to 0.936, a refractive index of 1.480 to 1.483, a freezing point of -18 to -27 ° C, and unsaturated acids such as linoleic acid and linolenic acid. Since it contains a large amount of 飽和 酸, it is rich in unsaturation and has an iodine value of 175 to 195, which corresponds to dry oil. The composition of fatty acids is 8-9% in saturated acid, 10-15% in oleic acid, 25-35% in linoleic acid, 35-45% in linolenic acid, 6.5% in oxygen acid, 0.5-1.5% in non-soapsulfate and glycerol The base is 4.5%.
건성유는 공기 중에 두면 산소를 흡수해서 축중합(縮重合)하여, 탄력성 있는 내수성(耐水性) 반투명의 고분자 물질인 리녹신을 발생하는데, 대기 중에서 1주일 동안 산소를흡수를 하면 20% 전후로 중량이 증가하는 것으로 알려져 있다.Dry oil absorbs oxygen when condensed in air, and condensation-polymerizes it to produce linoxin, an elastic, water-resistant, semi-transparent polymer material. When oxygen is absorbed for one week in the air, the weight is about 20%. It is known to increase.
이러한 오일의 원리를 이용하여, 본 발명에 적용하였다.Using the principle of this oil, it has been applied to the present invention.
즉, 본 발명은 오일에 에어레이션(aeration)를 하여, 산화를 촉진 시켜 탄력성 있고 내수(耐水) 성질을 갖는 가공 오일을 준비하고, 120∼150℃의 반응온도에서 오일과 목재를 8∼72시간동안 반응시키면, 분자량이 증가된 오일에서 열전도율이 높아지기때문에 목재 내에 함유하고 있는 수분을 급속히 탈수 시키면서, 건조시키는 시간을 월등히 단축시킬 수 있게 된다. 반응이 완료된 목재는 공간만 확보되면 별다른 조건 없이 보관하면 된다.In other words, the present invention is aeration (aeration) to the oil, to promote oxidation to prepare a resilient and water-proof processing oil, and the oil and wood at a reaction temperature of 120 ~ 150 ℃ for 8 to 72 hours When the reaction is carried out, the thermal conductivity is increased in the oil having an increased molecular weight, thereby rapidly dehydrating the water contained in the wood, and greatly shortening the drying time. Once the reaction is completed, the wood can be stored without any conditions as long as space is available.
이때, 가공된 오일과 가공할 목재를 120∼150℃에서 반응 하는 이유는 목재의 내부 온도가 120℃ 이하가 되었을 경우, 변칙적인 할렬(割裂)과 목재 표면에 과도한 오일 성분이 침투되어, 목재 표면을 가공할 시, 목재 표면의 자연적인 상태 유지가 어렵게 되기 때문이다.At this time, the reason why the processed oil and the wood to be processed at 120 to 150 ° C. is that when the internal temperature of the wood is 120 ° C. or less, anomalous splitting and excessive oil components penetrate the wood surface, thereby the wood surface. This is because when processing wood, it is difficult to maintain the natural state of the wood surface.
150℃ 이상의 온도에서는 추가 비용에 비해 목재 건조 효과가 미미하기 때문에 바람직하지가 않다.At temperatures above 150 ° C., the wood drying effect is negligible compared to the additional cost, which is undesirable.
또한, 오일과 목재의 반응시간에 있어서는 목재의 내부 온도가 상승하는 시간과 총 함유 수분에 따른 이탈시간에 따라 반응시간이 달라지게 되는데, 통상 건조를 위한 제재목의 직경이 5㎝ 내외인 내장용 목재인 경우에는 목재의 두께가 얇기 때문에 8시간 정도면 충분히 건조가 되며, 제재목의 직경이 40㎝ 이상인 경우에는 목재의 내부 온도 상승시간과 수분의 이탈시간이 길어짐으로 인하여 72시간 정도가 소요되기 된다. In addition, in the reaction time of the oil and wood, the reaction time varies depending on the time when the internal temperature of the wood rises and the departure time according to the total moisture content. The timber for drying is usually about 5 cm in diameter. In case of the thickness of the wood is thin enough to dry for about 8 hours, if the diameter of the lumber is more than 40cm it takes about 72 hours due to the increase in the internal temperature rise time of the wood and the escape time of moisture.
그 이상의 시간을 반응시킬 경우에는 지나친 탈수로 인해 할렬이 생기면서 목재의 가공성 및 경제성이 떨어지게 된다.If the reaction is longer than this, excessive dehydration may cause splitting, which may reduce the processability and economic efficiency of wood.
이와같이, 완료된 본 발명의 목재 건조방법은 할렬(割裂)이 방지되고, 강도(强度)가 높고 나무 무늬가 뚜렷한 품질 좋은 목재를 얻을 수 있어서, 경제성이 높을 것으로 예상된다.In this way, the wood drying method of the present invention completed is prevented from splitting, can be obtained a high-quality wood with high strength and clear wood pattern, it is expected to be economical high.
그리고, 건조된 본 발명의 목재는 표면에 오일막을 형성되기 때문에, 건조 후 외부로부터 추가의 수분 흡수를 원천적으로 막아주어 장시간 보관시에도 품질 좋은 목재를 제공할 수 있다.In addition, since the dried wood of the present invention forms an oil film on the surface, it prevents additional moisture absorption from the outside after drying, thereby providing a quality wood even when stored for a long time.
이는 나무의 건조를 급속히 진행시키기 때문에, 수분이 점유하였던 섬유조직의 부위가 축소되고, 따라서 전체적인 부피를 감소시킴으로써 섬유조직의 밀도를 높여 목재의 강도를 높이게 된 것이고, 제품 가공후 서서히 수분 증발에 의해 발생되는 목재의 균열현상 및 뒤틀림 현상 등의 단점이 해소되었기 때문이다.This accelerates the drying of the wood, which reduces the area of the fiber tissue occupied by water, thus reducing the overall volume, thereby increasing the density of the fiber tissue and increasing the strength of the wood. This is because the disadvantages such as cracking and warping of wood are eliminated.
한편, 본 발명의 오일은 사용하고 난 뒤, 폐기처리나 추가적인 정제 조작없이 계속해서 오일을 보충하기만 하면 계속해서 사용할 수 있는데, 이는 사용된 오일은 점성이 증가됨으로 열전도율이 더욱 좋아지기때문이다. On the other hand, after the oil of the present invention is used, it can be used continuously simply by replenishing the oil without waste disposal or additional refining operation, since the used oil has an improved viscosity due to its increased viscosity.

폭기조에 아마인유와 촉매제를 넣고, 20시간을 공기를 주입하면서 에어레이션한 후, 오일 탱크에 넣고 130℃로 가열하고, 가열된 아마인유는 이송하여 두께가 5㎝ 정도인 각재된 목재가 들어있는 목재 가공 탱크에 충전하였다. 그런 다음 목재 가공 탱크를 밀폐하고 반응온도를 130℃로 유지하면서 10시간동안 반응을 하였다.Put linseed oil and catalyst in the aeration tank, aerate for 20 hours while injecting air, put it in an oil tank, heat it to 130 ℃, transfer the heated linseed oil to the wood containing the lumber which is about 5cm thick. The processing tank was filled. Then, the wood processing tank was sealed and reacted for 10 hours while maintaining the reaction temperature at 130 ° C.
상기 본 발명의 의해 건조가 완료된 목재는 휴대용 고주파식 수분계 HM530 (용량: 20Mz, 디지탈 방식, 오차 :±0.5%; 일본)을 이용하여 건조 전과 비교하여 목재 함수율을 측정하였다. Wood dried by the present invention was measured for wood moisture content compared to before using a dry high frequency water meter HM530 (capacity: 20Mz, digital method, error: ± 0.5%; Japan).
도 1과 같이, 건조된 목재의 함수율이 초기 40.5%에서 본 발명의 실시 뒤, 20%로 감소됨을 확인할 수 있었다.As shown in Figure 1, the water content of the dried wood was confirmed to be reduced to 20% after the implementation of the present invention from the initial 40.5%.
또한, 도 2와 같이, 일반 건조에 실시된 목재에 비하여 나무 무늬의 선명도가 우수한 것을 확인할 수 있었다.In addition, as shown in Figure 2, it was confirmed that the vividness of the wood pattern is superior to the wood subjected to normal drying.
[실시예 2] 건조 처리후 재흡수율 비교 Example 2 Comparison of Resorption Rate after Drying Treatment
본 발명에 의한 건조방법으로 건조된 목재와, 열풍 건조로 처리한 목재에 있어서, 건조된 목재들의 수분 재흡수 과정을 비교 분석하였다.In the wood dried by the drying method according to the present invention, and wood treated by hot air drying, the water resorption process of the dried wood was analyzed.
서로 다른 방식에 의해 건조된 목재들을 9개월동안 같은 습도 조건의 장소에보관하면서, 초기 함수율이 15% 정도인 건조된 목재를 기준으로 시간이 경과함에 따른 함후율의 변동사항을 기재하여 수분의 재흡수율을 비교하였다.Keeping the wood dried in different ways in the same humidity condition for 9 months, the change in moisture content over time based on the dried wood with an initial moisture content of 15%, and Absorption rate was compared.
목재의 함수율 측정은 상기 실시예 1의 장비를 사용하여 측정하였다.The moisture content of the wood was measured using the equipment of Example 1 above.
열풍 인공 건조 방식과 자연 건조 방식 및 본 발명의 의한 오일건조방식에 의해 건조된 목재를 실험 대상으로 하였다.The wood dried by the hot air artificial drying method and the natural drying method and the oil drying method of the present invention was used as the test subject.
그 결과, 도 4와 같이 열풍인공 건조와 자연 건조된 목재는 9개월 동안 수분이 점차적으로 35%이상 상승하였으나, 본 발명에 의한 오일 건조 방식의 목재는 20∼23% 정도 까지만 수분이 상승한 후, 추가 함수율의 변화는 없었다.As a result, as shown in FIG. 4, the hot-air artificially dried and naturally dried wood gradually increased the moisture by more than 35% for 9 months, but the oil-dried wood according to the present invention increased the water only to about 20 to 23%. There was no change in additional moisture content.
이는, 오일막이 목재의 표면에 형성되어 수분의 재흡수를 억제하는 것으로 분석되며, 따라서, 장기간 보관시에도 목재 상태를 양호하게 유지 할 수 있어서, 추가 보관 비용을 절감할 수 있을 것으로 판단된다.It is analyzed that the oil film is formed on the surface of the wood to suppress the resorption of moisture, and therefore, it is judged that the wood state can be maintained well even during long-term storage, thereby reducing the additional storage cost.
이상과 같이, 본 발명은 오일을 재사용할 수 있어서, 생산 비용이 저렴하며, 목재의 수분제거 기간은 월등히 단축되면서, 강도는 향상되고, 나무 무늬는 선명하며, 비틀어짐이나 쪼개짐이 없고 보관성이 뛰어난 품질 좋은 목재를 제공할 수 있게 되었다.As described above, the present invention can reuse the oil, the production cost is low, while the moisture removal period of the wood is significantly shortened, the strength is improved, the wood pattern is clear, there is no twist or split and storage It is possible to provide good quality wood.
