본 발명은 건축자재 유해물질 측정용 시험기에 관한 것으로, 더 상세하게는 콘크리트나 벽지 및 장판지와 같은 건축자재로부터 방출되는 오염물질을 측정하는 시험기의 셀에 공급되는 온습도 정확성을 좋게 유지할 수 있어 측정치의 신뢰도를 향상시킬 수 있도록 발명된 것이다.The present invention relates to a tester for measuring harmful substances in building materials, and more particularly, it is possible to maintain a good temperature and humidity accuracy supplied to a cell of a tester for measuring pollutants emitted from building materials such as concrete, wallpaper, and cardboard. It is invented to improve the reliability.
일반적으로 새로 신축되는 건축 구조물 내지 내장재 등과 같은 각종 건축자재에는 유해물질이 포함되어 있다.In general, various building materials such as newly constructed building structures or interior materials include harmful substances.
즉, 콘크리트와 같은 골격구조물은 물론 벽지, 장판지 등과 같은 각종 내장재를 부착하기 위한 접착제에서 포름알데히드 및 휘발성 유기화합물(VOC) 등과 같은 유해물질이 장시간에 걸쳐 서서히 방출되어 질병유발과 같이 인체에 심각한 피해를 주는 것으로 알려져 있다.That is, harmful substances such as formaldehyde and volatile organic compounds (VOC) are gradually released from the adhesive for attaching various interior materials such as wallpaper and floorboard as well as concrete structures such as concrete, causing serious damage to the human body such as disease. It is known to give.
따라서, 최근에는 각종 건재 및 시공재의 재료로부터 유해물질 방출 여부 및 방출되는 시간 등을 시험하기 위한 시험기가 제안되어 그 데이터를 활용하고 있다.Therefore, in recent years, a tester for testing the release and release time of harmful substances from various building materials and construction materials has been proposed and utilizes the data.
건축자재 유해물질 측정용 시험기는 도 1에서 도시한 바와 같이 에어발생기(11)에서 생성된 공기를 크린에어공급기(10)를 거쳐 공기에 포함된 각종 이물질을 여러 필터를 단계별로 거치면서 제거하여 청정공기를 항온챔버(1)내로 공급하게 된다.As shown in FIG. 1, a tester for measuring harmful materials for building materials removes air generated by the air generator 11 through a clean air supplier 10, and removes various foreign substances contained in the air by passing through various filters step by step. Air is supplied into the thermostatic chamber 1.
항온챔버(1) 내에는 시편(S)을 완전하게 밀폐상태로 보관하고 있는 셀(30)들과 온습도유니트(20)가 구비된다.In the constant temperature chamber 1, the cells 30 and the temperature-humidity unit 20 which hold the specimen S in a completely closed state are provided.
온습도유니트(20)는 셀(30)로 공급되는 공기를 일정한 온도와 습도를 유지한 상태로 일정하게 정략적으로 공급하여 실내환경과 유사한 조건을 가지며 환기가 지속적으로 이루어지도록 회로가 형성되어 있다.Temperature-humidity unit 20 is a circuit is formed so that the air to be supplied to the cell 30 regularly and regularly while maintaining a constant temperature and humidity have a condition similar to the indoor environment and the ventilation is continuously made.
셀(30)은 덮개가 착탈가능한 상태로 시편(S)의 내장 및 교체가 가능하도록 하되, 닫힌상태에서는 완전한 밀폐상태를 유지하게 된다.Cell 30 is to allow the built-in and replacement of the specimen (S) in a removable cover state, but in a closed state to maintain a completely closed state.
시편(S)은 시험하고자 하는 건축자재를 적정 크기로 절단하여 셀(30)의 내부에 넣어서 위치하게 된다.Specimen (S) is to be placed in the interior of the cell 30 by cutting the building material to be tested to an appropriate size.
온습도유니트(20)는 크린에어공급기(10)로부터 공급되는 건공기와 습공기가 인입된 후 혼합시킨 상태로 셀(30)에 공급할 때, 그 온도 및 습도를 콘트롤러(22)에서 관측할 수 있도록 센서(21)가 내장되어 있다.When the temperature and humidity unit 20 supplies the dry air and the wet air supplied from the clean air supply 10 to the cell 30 in a mixed state after being introduced, the sensor 22 can monitor the temperature and humidity at the controller 22. 21 is built in.
그리고, 셀(30)에는 MFC펌프(41)의 작동으로 셀(30) 내부의 공기를 배출시킬 때 흡착관(40)을 거치도록 회로를 형성하여 이 흡착관(40)에 흡착된 각종 이물질을 검사하기 위해 흡착관(40)을 추후 분리하여 도시하지 않은 별도의 분석장치에서 이물질 포함여부 및 그 농도 등을 분석하는 것이다.In addition, the cell 30 forms a circuit to pass through the adsorption tube 40 when the air inside the cell 30 is discharged by the operation of the MFC pump 41 to collect various foreign substances adsorbed to the adsorption tube 40. In order to examine the separation of the adsorption tube 40 afterwards to analyze the inclusion of foreign matter and its concentration in a separate analysis device (not shown).
도 1에서 도시한 바와 같이 구성된 종래 건축자재 유해물질 측정용 시험기는 크린에어공급기(10)에서 여과된 청정 건공기 및 습공기가 온습도유니트(20)로 공급될 때 직접 연결된 관을 통해 인입된 후 다시 셀(30)로 공급되므로써, 건공기와 습공기가 완전한 혼합이 이루어지지 못하므로써 원하는 온도 및 습도 콘트롤 수치와의 큰 편차가 발생하였던 것이다.The conventional test equipment for measuring hazardous materials for building materials constructed as shown in FIG. 1 is introduced through a pipe directly connected when clean dry air and wet air filtered from a clean air supplier 10 are supplied to a temperature and humidity unit 20. As it is supplied to the cell 30, the dry air and the wet air are not completely mixed, which causes a large deviation from the desired temperature and humidity control values.
따라서, 온도와 습도의 정확도 편차가 넓어서(온도:±1℃, 습도:±5%) 얻어진 수치의 신뢰도가 낮아지는 문제점이 있었던 것이다. Therefore, there is a problem in that the accuracy of the obtained numerical value is lowered because the accuracy deviation between temperature and humidity is wide (temperature: ± 1 ° C., humidity: ± 5%).
본 발명의 목적은 에어크리너에서 공급되는 건공기와 습공기를 보다 완전하게 혼합시켜 실내환경과 가장 유사한 조건에서 수치를 얻을 수 있도록 한 건축자재 유해물질 측정용 시험기를 제공하는 데 있다.An object of the present invention is to provide a tester for measuring the harmful substances of building materials to more completely mix the dry and wet air supplied from the air cleaner to obtain a value in the conditions most similar to the indoor environment.

상기 크린에어공급기(10)에서 발생된 건공기 및 습공기를 인입하여 센서(21)에 의해 온도 및 습도를 콘트롤러(22)에서 표시와 함과 제어하는 온습도유니트(20)와;A temperature / humidity unit 20 for introducing the dry air and the wet air generated by the clean air supplier 10 to display and control the temperature and humidity by the sensor 21 with the display of the controller 22;
상기 온습도유니트(20)를 통과한 건공기와 습공기가 배관을 통해 유입되며 속이빈 내부로 건축자재 시편(S)이 밀폐된 상태로 내장된 상태로 크린에어공급기(10) 측으로 환기되며 실내 유사환경을 갖도록 하는 셀(30)과;The dry air and the wet air passing through the temperature and humidity unit 20 are introduced through the pipe, and the building material specimen S is enclosed in a hollow state and ventilated toward the clean air supply 10 in a sealed state. A cell 30 to have;
이 셀(30)의 내부와 연통되게 배관되어 MFC펌프(41)의 작동으로 셀(30) 내부의 공기를 강제 배출시킬 때 내부에 채워진 흡착물질에 각종 유해물질이 흡착되어 포집토록 하는 흡착관(40)으로 구성된 것에 있어서;Adsorption tube which is piped in communication with the inside of the cell 30 to allow various harmful substances to be adsorbed to the adsorption material filled inside when the air in the cell 30 is forcibly discharged by the operation of the MFC pump 41 ( Consisting of 40);
상기 크린에어공급기(10)와 온습도유니트(20) 사이에 와류혼합코일(50)이 더 설치되는 것에 의해 달성된다.The vortex mixing coil 50 is further provided between the clean air supplier 10 and the temperature and humidity unit 20.
따라서, 건공기와 습공기를 보다 완전하게 혼합하여 실내환경과 가장 유사한 조건으로 셀에 공급하므로 분석의 정확성과 신뢰성을 향상시킬 수 있는 것이다.Therefore, it is possible to improve the accuracy and reliability of the analysis by supplying the cells with the conditions most similar to the indoor environment by mixing the dry and wet air more completely.
이하 본 발명의 바람직한 실시예를 첨부된 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 종래 건축자재 유해물질 측정용 시험기를 보인 장치도이고, 도 2는 본 발명의 건축자재 유해물질 측정용 시험기를 보인 장치도로 크린에어공급기(10)와 온습도유니트(20) 사이에 와류혼합코일(50)이 더 설치되는 것을 보이고 있다.1 is a device diagram showing a tester for measuring the hazardous materials of conventional building materials, Figure 2 is a device diagram showing a tester for measuring the hazardous materials of building materials of the present invention vortex mixing between the clean air supplier (10) and the temperature and humidity unit (20) It is shown that the coil 50 is further installed.
즉, 콤프레셔 구조의 에어발생기(11)는 외부 공기를 강제적으로 크린에어공급기(10)로 공급하게 되면, 외부 공기에 포함된 각종 이물질을 여과하게 된다.That is, when the air generator 11 of the compressor structure forcibly supplies external air to the clean air supplier 10, various foreign substances contained in the external air are filtered out.
크린에어공급기(10)는 여러 기능의 필터들이 단계별로 다수개 구비되어 이 필터들을 각각 거치면서 제거하여 청정공기를 항온챔버(1) 내에 위치되는 온습도유니트(20)를 거쳐 셀(30)로 배관된 호스를 통해 공급하게 된다.The clean air supplier 10 is provided with a plurality of filters having a plurality of functions in stages to remove them while passing through the filters, respectively, and pipe the clean air to the cell 30 via the temperature and humidity unit 20 located in the constant temperature chamber 1. Through the supplied hose.
크린에어공급기(10)에서 청정된 공기에는 건공기와 물을 통과하여 얻어진 습공기로 각각 생성하여 온습도유니트(20)로 공급하게 되는데 이때, 두 건공기와 습공기가 보다 완전하게 혼합될 수 있도록 하기 위해 본 발명에서는 도 2에서와 같이 와류혼합코일(50)이 설치된다.Clean air from the air supply (10) to the air generated by passing through the dry air and water, respectively, is supplied to the temperature and humidity unit (20), in order to ensure that the two dry air and the wet air more completely mixed In the present invention, the vortex mixing coil 50 is installed as shown in FIG.
와류혼합코일(50)은 가늘고 긴 파이프를 코일형으로 다수회 권취시킨 구조로 이 와류혼합코일(50)을 통과 할 때 건공기와 습공기가 완전하게 혼합된 후 온습도유니트(20)로 공급되어 실제 실내환경에서와 같은 공기 조건을 갖도록 하는 것이다.The vortex mixing coil 50 is a structure in which a thin pipe is wound many times in a coil shape. When the vortex mixing coil 50 passes through the vortex mixing coil 50, the dry air and the wet air are completely mixed and then supplied to the temperature and humidity unit 20. It is to have the same air condition as indoor environment.
온습도유니트(20)는 셀(30)로 공급되는 공기를 일정한 온도와 습도를 유지한 상태로 일정하게 정략적으로 공급하여 실내환경과 유사한 조건을 가지며 환기가 지속적으로 이루어지도록 호수 배관이 형성되며, 그 온도 및 습도를 콘트롤러(22)의 모니터에서 관측, 제어할 수 있도록 센서(21)가 내장되어 있다.The temperature and humidity unit 20 supplies the air supplied to the cell 30 regularly and regularly while maintaining a constant temperature and humidity, and has a similar condition to an indoor environment, and a lake pipe is formed so that ventilation is continuously performed. The sensor 21 is built in so that temperature and humidity can be observed and controlled on the monitor of the controller 22.
셀(30)은 상부에 덮개가 착탈가능한 구조로 내부에 시편(S)을 내장 및 교체가 가능케 하는데, 닫힌 상태에서는 완전한 밀폐상태를 유지하여 외부 이물질이나 습도 등에 의해 시편(S)의 검측에 지장을 주지 않토록 밀폐상태로 항온챔버(1) 내에 위치된다.The cell 30 has a structure in which the cover is detachable at the top, which enables the internal and replacement of the specimen S. In the closed state, the cell 30 is maintained in a completely closed state, which prevents the detection of the specimen S by external foreign matter or humidity. It is located in the thermostatic chamber 1 in a sealed state so as not to be affected.
시편(S)은 시험하고자 하는 건축자재, 즉 바닥재나 벽지 등을 적정 크기로 절단하여 셀(30)의 내부에 넣어서 위치하게 된다.Specimen (S) is to be placed in the interior of the cell 30 by cutting the building material to be tested, that is, flooring or wallpaper to an appropriate size.
따라서, 이물질이 거의 없는 순수 공기를 실내환경과 유사한 온도와 습도를 유지한 상태로 환기조건을 만들게 되는데, 시편(S)이 내장된 셀(30)에는 환기순환호스(31)와 "T" 배관 방식으로 흡착관(40)을 연결하게 된다.Therefore, the pure air is almost free from foreign matters to create a ventilation condition in a state of maintaining a temperature and humidity similar to the indoor environment, the cell (30) containing the specimen (S) ventilation circulation hose 31 and "T" piping The adsorption tube 40 is connected in a manner.
흡착관(40)은 MFC펌프(41)의 작동으로 셀(30) 내부의 공기를 배출시킬 때 흡착관(40)을 거치도록 회로를 형성하여 흡착물질로 채워진 이 흡착관(40)에 흡착된 각종 이물질을 검사하는 것이다.The adsorption pipe 40 forms a circuit to pass through the adsorption pipe 40 when the air inside the cell 30 is discharged by the operation of the MFC pump 41 and is adsorbed to the adsorption pipe 40 filled with the adsorption material. It is to inspect various foreign objects.
흡착관(40)은 추후 분리하여 도시하지 않은 별도의 분석장치에서 이물질 포함여부 및 그 농도 등을 분석하는 것이다.Adsorption tube 40 is to be separated later to analyze the inclusion and the concentration of foreign matter in a separate analysis device not shown.
흡착관(40)과 셀(30) 사이에는 필요시 통로 개방을 제어하기 위한 밸브(42)가 구비된다.A valve 42 is provided between the adsorption tube 40 and the cell 30 for controlling passage opening if necessary.
이와 같이 가늘고 긴 와류혼합코일(50)에 의해 건공기와 습공기가 완전 혼합됨과 아울러, 셀(30) 내부의 환경 및 대기압을 실제 조건과 최대한 가깝게 유지할 수 있는 것이다.Dry and wet air is completely mixed by the elongated vortex mixing coil 50 as described above, and the environment and atmospheric pressure inside the cell 30 can be maintained as close as possible to actual conditions.
따라서, 본 발명에 의해 얻어지는 셀(30) 내부의 온도 및 습도의 정확도를 시험결과에 의하면, 온도:±0.2℃, 습도:±2% 범위 내로 편차를 줄일 수 있어 건축자재의 유해물질 분석으로 얻어지는 시험 테이터의 정확도 및 신뢰성을 보다 향상시킬 수 있는 것이다.Therefore, according to the test results of the accuracy of the temperature and humidity inside the cell 30 obtained by the present invention, the deviation can be reduced within the range of temperature: ± 0.2 ℃, humidity: ± 2%, which is obtained by analysis of harmful substances of building materials This can further improve the accuracy and reliability of the test data.
한편, 온습도유니트(20)의 일측에 항온챔버(1)와 연통된 상태로 가늘고 긴 코일형의 저항관(60)을 설치하는 것이 바람직 하다.On the other hand, it is preferable to install a long, coil-shaped resistance tube 60 in a state in communication with the constant temperature chamber 1 on one side of the temperature and humidity unit 20.
이 저항관(60)은 셀(30) 내부의 압력을 작게 하고, 온습도의 안정을 유지하는데 도움을 주게 된다.This resistance tube 60 helps to reduce the pressure inside the cell 30 and to maintain the stability of temperature and humidity.
상술한 바와 같은 본 발명은, 와류혼합코일(50)에 의해 건공기와 습공기가 완전 혼합됨과 아울러, 셀(30) 내부의 환경 및 대기압을 실제 조건과 최대한 가깝게 유지할 수 있다.In the present invention as described above, the dry air and the wet air are completely mixed by the vortex mixing coil 50, and the environment and atmospheric pressure inside the cell 30 can be maintained as close as possible to the actual conditions.
따라서, 시편에서부터 발생되는 유해물질들을 정확하게 분석, 대응할 수 있어 분석의 정확성과 신뢰성을 향상시키는 등의 매우 유용한 발명인 것이다.Therefore, it is a very useful invention that can accurately analyze and respond to harmful substances generated from the specimen, thereby improving the accuracy and reliability of the analysis.
