Description
본 발명은 전기전도도를 이용하는 목재 방부 약액의 농도를 측정하는 방법에 관한 것이다. The present invention relates to a method of measuring the concentration of a wood preservative chemical using electrical conductivity.
웰빙(Well-being) 시대의 도래와 함께 주거환경에 대한 관심이 높아짐에 따라 환경 및 인체 친화적인 목재의 수요는 매년 증가하고 있으며 건축용재, 조경시설재 등 다양한 용도로 다량 사용되고 있다. 목재는 유기물인 세포와 미세한 공극으로 구성되어 있어 사용 중에 열악한 환경조건에 노출되었을 경우 쉽게 미생물 열화(부후)가 발생하여 물적 또는 인적피해를 발생시킬 수 있다. 그동안 목재의 내구성 증대를 위하여 많은 종류의 목재방부제가 개발되어 방부처리 목재 생산에 사용되어 왔으며 목재는 방부처리에 의해 사용수명을 최대 20년까지 연장할 수 있어 경제적 가치는 매우 높다. 한미 FTA가 발효되고 이어서 우리나라의 주요 목재 수입국인 호주, 뉴질랜드와의 FTA 협상 타결이 예정되어 있고 그 밖에 한중, 한일, 한중일, 인도네시아 등과도 협상이 개시될 예정인 것으로 알려져 있어 국내 목재 방부산업을 포함한 목재산업 보호를 위한 대책이 시급하다. With the advent of the well-being era and increasing interest in the residential environment, the demand for environmentally and human-friendly wood is increasing every year, and it is widely used for various purposes such as construction materials and landscape facilities. Wood is composed of organic cells and fine pores, so when exposed to poor environmental conditions during use, microbial deterioration (deterioration) can easily occur, causing physical or human damage. In the meantime, many types of wood preservatives have been developed to increase the durability of wood and have been used in the production of preservative wood, and wood has a very high economic value as the life of wood can be extended up to 20 years by preservative treatment. Following the entry into force of the Korea-US FTA, FTA negotiations with Australia and New Zealand, which are major timber importers in Korea, are scheduled to be concluded. In addition, negotiations with Korea-China, Korea-Japan, Korea-China-Japan, and Indonesia are also known to be initiated. Measures for industrial protection are urgent.
국산 방부목재의 국제 경쟁력 제고를 위해서는 현재와 같은 현장 작업자의 경험에 의한 후진국형 생산방식에서 벗어나 자동화된 시스템 하에서 철저한 품질관리를 거쳐 기술력으로 생산하는 선진국형으로 전환되어야 하며 이를 위해서는 기술개발이 선행되어야 한다. 산업혁명 이후 화석연료 사용에 의한 대기 중의 CO2 농도 증가로 지구온난화 현상이 초래되어 범세계적으로 온실가스 감축에 노력하고 있다. 산림은 기후변화협약에서 유일하게 탄소 흡수원으로 인정받고 있으며 여기에서 수확되는 목재는 우수한 이산화탄소의 저장고라고 할 수 있다. 2011년 말에 개최된 제17차 UN 기후변화협약 당사국총회(COP17)와 제7차 교토의정서 당사국회의(CMP7)에서 벌채목재제품(HWP, harvested wood product)의 탄소저장효과가 평가되어 탄소 축적량의 탄소계정 항목으로 인정하고 있다. CO2 배출량 세계 10위로 온실가스 의무감축국으로 지정될 것이 확실시되고 있는 우리나라로서는 탄소 축적량을 최대한 확충하여 그에 상응하는 만큼 탄소 배출권을 최대한 인정받기 위해서는 목재이용 확대 정책이 필요하다. 특히 방부처리 목재와 같이 내구성이 있는 제품의 생산과 사용 확대는 탄소 축적기간의 연장과 탄소 축적량의 증대로 이어져 탄소배출권 확충효과를 배가시킬 수 있다. 따라서 온실가스 감축 의무국으로 지정될 우리나라로서는 방부처리 목재의 생산량과 사용량을 증대시킬수록 CO2를 배출하는 산업생산 활동의 제한과 부담을 크게 완화시킬 수 있다. 목재 자급율이 10% 수준으로 부족한 90%는 전적으로 해외수입에 의존하고 있는 국내 목재 수급상황에서 고내구성의 방부목재 사용은 목재의 소비 절약 효과를 가져와 목재 자급율 향상과 외화절약에도 기여할 수 있다. 최근 목재 수요 증대와 함께 방부처리 목재 사용도 꾸준히 늘어남에 따라 산업체수가 급증하여 전국적으로 50여개 업체가 가동 중인 것으로 파악되고 있으며 국내 시장규모도 4,000억원에 이르는 것으로 알려져 있다. 국립산림과학원에서는 '방부목재의 규격과 품질'에 관한 기준을 고시하여 규격품의 생산과 유통을 권장하고 있다. 그러나 산업체와 시장 규모가 급진적으로 확대됨에 따라 업체 간의 과다한 경쟁과 일부 신생 업체의 방부목재에 대한 지식과 기술력 부족으로 불량 방부목재가 양산, 유통됨으로써 제품에 대한 불신과 함께 민원이 제기되는 등 많은 문제점이 발생하고 있다. 산림청 지원으로 서울, 중부(대전, 충남북), 남부(광주, 전남, 경남)지역의 각 10개소, 총 30개소에 설치(2008년~2010년 시공)되어 있는 방부처리 조경시설물을 대상으로 품질분석을 실시한 결과, 남부지역 시설물 1개소(경남 진주시)에서만 유일하게 흡수량 기준을 충족(침윤도는 기준 미달)하였을 뿐 나머지 29개소의 시설물 모두는 사용환경범주 H3 또는 H4 환경에 사용되었음에도 불구하고 이 기준에 미달하는 것으로 밝혀져 한국의 불량 방부목재 생산 및 시공 실태가 매우 심각한 것으로 밝혀졌다(국내 방부목재 품질 시험방법 개선 및 관리방안. 2011. 산림청). 본인이 조사한 중부지역 1개소를 예를 들어 살펴보면, 사용환경범주 H3에 사용된 ACQ 처리 데크재의 경우 약제 침윤도는 80% 이상, 흡수량은 2.6kg/m3 이상 되어야 함에도 불구하고 조사 결과는 침윤도가 평균 20%, 흡수량이 평균 1.55kg/m3에 불과해 국내 불량 방부목의 생산과 시공 실태를 여실히 보여주고 있으며 이로 인해 일부 데크재에서는 부후가 발생하였다.In order to enhance the international competitiveness of domestic preservative wood, it is necessary to shift from the currently developed country type production method based on the experience of field workers to the advanced country type that produces technology through thorough quality control under an automated system. For this, technology development must be preceded. . Since the Industrial Revolution, global warming has been caused by an increase in the concentration of CO 2 in the atmosphere due to the use of fossil fuels, and efforts are being made to reduce greenhouse gases worldwide. Forests are recognized as the only carbon sink in the Convention on Climate Change, and the timber harvested here is an excellent storage of carbon dioxide. The carbon storage effect of harvested wood products (HWP) was evaluated at the 17th General Assembly of the Parties to the UN Climate Change Convention (COP17) and the 7th Kyoto Protocol (CMP7) held at the end of 2011. Is recognized as a carbon account item As it is certain that Korea will be designated as the world's 10th largest greenhouse gas reduction country with CO 2 emissions, it is necessary to expand the use of wood in order to maximize the amount of carbon stocks and to be recognized as much as possible. In particular, the expansion of the production and use of durable products such as preservative wood leads to an increase in carbon accumulation period and carbon accumulation, which can double the effect of expanding carbon credits. Therefore, for Korea, which will be designated as a country obligated to reduce greenhouse gases, the more the production and use of preservative wood is increased, the more restrictions and burdens on industrial production activities that emit CO 2 can be greatly eased. In the domestic timber supply and demand situation, where the timber self-sufficiency rate is at the 10% level, 90% is entirely dependent on overseas imports. With the recent increase in wood demand and the steadily increasing use of preservative wood, the number of industries has increased rapidly, and it is believed that 50 companies are operating nationwide, and the domestic market is known to reach 400 billion won. The National Academy of Forest Sciences recommends the production and distribution of standard products by notifying the standards on'standards and quality of preservative wood'. However, as the size of the industry and the market expands radically, there are many problems, such as excessive competition between companies and the lack of knowledge and technology of some startups, resulting in mass production and distribution of defective preservatives, resulting in distrust of products and complaints. Is occurring. Quality analysis of preservation treatment landscape facilities installed in each of 10 locations in Seoul, Central (Daejeon, North Chungcheong) and South (Gwangju, Jeonnam, Gyeongnam) with support from the Forest Service (construction from 2008 to 2010) As a result of the implementation, only one facility in the southern region (Jinju-si, Gyeongnam) met the water absorption standard (infiltration level was less than the standard), but all of the remaining 29 facilities were used in the environment category H3 or H4. As it was found to be insufficient, it was found that the production and construction of defective preservative wood in Korea was very serious (improvement and management plan for the quality test method of preservative wood in Korea. 2011. Forest Service). Looking at one of the central regions that I investigated, for example, the ACQ-treated deck material used in the usage environment category H3 should have a drug penetration of 80% or more and an absorption of 2.6kg/m 3 or more. With only 20% and an average absorption of 1.55kg/m 3 , it clearly shows the production and construction of defective preservatives in Korea, and this caused stiffness in some deck materials.
이에 따라 산림청에서는 불량 방부처리 목재의 생산과 유통을 근절하고 소비자 피해를 예방하기 위하여 그동안 사문화 되어 있던 '산림자원 조성 및 관리에 관한 법률' 제39조(임산물 규격의 고시)에 근거하여 '방부처리 목재 품질표시제'를 2011년부터 전면 시행하고 단속을 점차 강화하고 있다. 목재플라스틱복합체(구명칭 합성목재)에 빼앗긴 시장을 되찾아오고 방부목재 산업의 활성화와 시장 확대를 위해서는 지금까지 해왔던 저품질 물량 위주의 생산방식에서 탈피하고 규격과 기준에 맞는 균일한 품질의 제품을 생산, 공급하여 소비자로부터 신뢰를 회복해야 한다. 우수한 품질의 방부목재 생산을 유도하고 한미 FTA 발효와 함께 국내 방부목재 산업의 경쟁력을 제고시키기 위해서는 제품 생산과 품질관리를 위한 기술개발이 필요하나 지금까지 이루어지지 않고 있다. 현재 방부목재 생산현장에서는 제품의 품질을 좌우하는 약액의 농도 관리를 현장 작업자의 경험에 의존하고 있어 불량 제품 생산의 근원이 되고 있다.Accordingly, in order to eradicate the production and distribution of poorly preserved timber and prevent damage to consumers, the Forest Service has been ``preservative treatment'' based on Article 39 (Notification of Forest Product Standards), which has been privately cultured so far. The'wood quality labeling system' has been fully implemented since 2011, and the crackdown has been gradually strengthened. To regain the market lost to the wood-plastic composite (formerly known as synthetic wood) and to revitalize the preservative wood industry and expand the market, we break away from the low-quality production method that we have been doing so far, and produce products of uniform quality that meet standards and standards. , Supply and restore trust from consumers. In order to induce the production of high-quality preservative wood and enhance the competitiveness of the domestic preservative wood industry along with the entry into force of the Korea-US FTA, technology development for product production and quality control is necessary, but has not been done so far. Currently, the preservative timber production site relies on the experience of field workers to manage the concentration of chemicals that influence the quality of products, which is the source of the production of defective products.
한편, 전기전도도를 이용하여 특정성분의 농도를 측정하는 기술로는 한국환경농화학회지 제18권 제2호에 개시된 수원과 안성지역 빗물의 화학성분 조성이 있으나, 본 발명의 전기전도도를 이용하는 목재 방부 약액의 농도를 측정하는 방법에 대해서 개시된 바는 없다. On the other hand, as a technology for measuring the concentration of a specific component using electrical conductivity, there is a chemical composition composition of rainwater in Suwon and Anseong area disclosed in Vol. 18, No. 2 of the Korean Journal of Environmental Agrochemicals. There is no disclosed method for measuring the concentration of the chemical solution.
방부 목재의 제조 시 목재 방부 약액을 재사용하는 경우, 목재 방부 약액의 농도를 정확하게 구하지 않고, 초기에 제조한 목재 방부 약액의 부피가 줄어든 정도로부터 대략적으로 부피와 농도를 맞춰 사용해 왔다. 따라서 목재 방부 약액의 농도가 부정확하여 방부 목재의 불량품이 발생하는 문제점이 종종 발생하고 있다. 이를 해소하기 위하여, 본 발명은 전기전도도를 이용하는 목재 방부 약액의 농도를 측정하는 방법을 제공하고, 방부 목재의 제조과정에서, 전기전도도의 측정을 통해 간편하게 정확한 목재 방부 약액의 농도를 구할 수 있다는 것을 확인함으로써, 본 발명을 완성하였다.When the wood antiseptic chemical solution is reused in the manufacture of preservative wood, the concentration of the wood antiseptic chemical solution is not accurately determined, and the volume and concentration have been approximately adjusted from the extent that the volume of the initially prepared wood antiseptic chemical solution is reduced. Therefore, there is often a problem that defective products of the preservative wood occur due to inaccurate concentration of the wood antiseptic chemical solution. In order to solve this, the present invention provides a method of measuring the concentration of the wood preservative chemical using electrical conductivity, and in the manufacturing process of the preservative wood, it is possible to obtain an accurate concentration of the wood preservative chemical simply by measuring the electrical conductivity. By confirming, the present invention was completed.
