당사는 (주)포스콘 진공 사업 부분이 분사하여 1999년 1월 진공 장비 및 제어계측 분야 독립 법인체를 설립하였으며 당사의 주력 제품은 초고진공용 Ion pump 및 controller로서 국산화 개발하여 생산 판매하고 있다. Ion pump 와 controller는 10-4 ~ 10-10 Torr 범위의 초고진공으로 진공 시스템을 배기할 수 있는 장비로서 무소음, 무진동, 저전력의 특성을 가진 초정밀, 초청정 진공 실험에 없어서는 안 될 펌프이다. 현재 당사는 과학기술부의 특정연구개발 과제를 극고진공(XHV)용 Ion Pump를 개발하고 있는 중이다.

This study was performed to test the combustive properties of pinus rigida specimens treated with bis-(dimethylaminomethyl) phosphinic acid, bis-(diethylaminomethyl) phosphinic acid (DEDAP), and bis-(dibuthylaminomethyl) phosphinic acid. Pinus rigida specimens were painted in three times with 15 wt% bis-(dialkylaminoalkyl) phosphinic acid solutions at the room temperature. After drying the treated specimens, combustive properties were examined by the cone calorimeter (ISO 5660-1). Combustion-retardation properties were found to be improved partially due to the treated bis-(dialkylaminoalkyl) phosphinic acids in the virgin pinus rigida. In particular, the specimens treated with DEDAP showed both the lower total heat release rate ($60.9MJ/m^2$) and effective heat of combustion (15.20 MJ/kg) than those of virgin plates. Compared with virgin pinus rigida plates, specimens treated with the bis-dialkylamimoalkyl phosphinic acid derivatives showed partially low combustive properties.

EBOP(Electrical Balance of Plant)는 직류의 연료전지의 출력을 전력전자기술을 이용해 계통전원에 연계 가능한 교류로 변환해주는 일련의 시스템을 칭한다. 포스콘에서는 용융탄산염 연료 전지(Molten Carbonate Fuel Cell, MCFC)를 이용한 3MW 발전용 연료전지 EBOP 시스템을 개발하였으며, 국제규격(IEEE std.1547, UL1741)에 준하는 시험을 통해 성능검증을 완료함으로써 MW급 EBOP 시스템의 국산화에 성공하였다.

This study was performed to test the combustive properties of Medium Density Fibreboard (MDF) specimens treated with piperazinomethyl-bis-phosphonic acid (PIPEABP), methylpiperazinomethyl-bis-phosphonic acid (MPIPEABP), and N,N-dimethylethylenediaminomethyl-bis-phosphonic acid (MDEDAP). MDF Plates were painted in three times with 15 wt% solution of the alkylenediaminoalkyl-bis-phosphonic acids at the room temperature, respectively. After drying specimen treated with chemicals, combustive properties were examined by the cone calorimeter (ISO 5660-1). It was indicated that the specimens treated with chemicals showed the later time to peak mass loss rate ($TMLR_{peak}$) = (340475) s than that of virgin plate by reducing the burning rate. In adition, the specimens treated with chemicals showed the higher $CO_{mean}$ production (0.0883~0.0963) kg/kg than that of virgin plate. Especially, the specimens treated with chemicals showed the higher mean smoke extinction area ($SEA_{mean}$) ($5m^2/kg{\sim}21.5m^2/kg$) than that of virgin plate. Thus, It is supposed that the combustion-retardation properties were improved by the partial due to the treated alkylenediaminoalkyl-bis-phosphonic acids in the virgin MDF Plate. However, It gave a negative effect on smoke reduction.

This study was performed to test the combustive properties of Medium Density Fibreboards (MDFs) treated with chemicals of the bis-(dimethylaminomethyl) phosphinic acid (DMDAP), N,N-dimethylethylenediaminomethyl-bis-phosphonic acid (DMDEDAP), piperazinomethyl-bis-phosphonic acid (PIPEABP), and methylpiperazinomethyl-bis-phosphonic acid (MPIPEABP). MDFs were painted in three times with 15 wt% solution of the bis-(dimethylaminomethyl) phosphinic acid and alkylenediaminoalkyl-bis-phosphonic acids at the room temperature, respectively. After drying MDF treated with chemicals, combustive properties and volatile organic compounds (VOCs) contents were examined by the cone calorimeter (ISO 5660-1), test for flame retardant (NEMA Notice No. 2012034), and gas chromatography (KS M ISO 11890-2), respectively. It was indicated that the MDFs treated with chemicals showed the longer time to combustion time (CT) = (442~492) s than that of virgin plate by reducing the burning rate except for CT treated with DMDAP. In adition, the MDFs treated with chemicals showed both of the higher char area (44.33~61.33) kg/kg and char length (10.33~11.67) cm than those of virgin plate. Especially, the MDFs treated with chemicals showed the higher mean volatile organic compounds (VOCs) (0.188~0.333) g/L than that of virgin plate within the prescribed limits. Thus, It is supposed that the combustion- retardation properties were improved by the partial due to the treated chemicals in the virgin MDF.

This study was performed to test combustive properties of medium density fibreboard (MDF) plates treated with piperazinomethyl-bis-phosphonic acid (PIPEABP), methylpiperazinomethyl-bis-phosphonic acid (MPIPEABP), and N,N-dimethylethylenediaminomethyl-bis-phosphonic acid (MDEDAP). MDF specimens were painted three times with 15 wt% solution of the alkylenediaminoalkyl-bis-phosphonic acids at room temperature. After drying specimen treated with chemicals, combustive properties were examined using the cone calorimeter (ISO 5660-1). As a result, combustion-retardation properties increased due to the treatment of bare MDF with alkylenediaminoalkyl-bis-phosphonic acid solution. Especially, the specimens treated with chemicals showed the ignition (TTI) (148 s~116 s) was retarded and the flameout (Tf) (633 s~529 s) time increased, while the total heat release rate (THRR) (61.1~67.0) $MJ/m^2$ was lowered than those of using virgin plate by reducing the burnig rate. Compared with virgin MDF plate, the specimens treated with the alkylenediaminoalkyl-bis-phosphonic acids showed low combustive properties. However the specimens treated with bis-(dimethylaminomethyl) phosphinic acid (DMDP) showed the higher peak heat release rate (PHRR) ($185.08kW/m^2$) than that of the virgin plate.

This study was performed to test the combustive properties of pinus rigida specimens treated with methylpiperazinomethyl-bis-phosphonic acid $M^{n+}$ ($PIPEABPM^{n+}$)s and methylpiperazinomethyl-bis-phosphonic acid (PIPEABP). Pinus rigida Plates were painted in three times with 15 wt% $PIPEABPM^{n+}s$ and PIPEABP solutions at the room temperature respectively. After drying specimen treated with chemicals, combustive properties were examined by the cone calorimeter (ISO 5660-1). It was indicated that the specimens treated with $PIPEABPM^{n+}s$ showed the lower speed to peak mass loss rate ($MLR_{peak}$), (0.104~0.121) g/s than that of PIPEABP plate. In adition, the specimens treated with $PIPEABPM^{n+}s$ showed both the lower total smoke release rate (TSRR), (224.4~484.0) $m^2/m^2$ and $CO_{mean}$ production (0.0537~0.0628) kg/kg than those of PIPEAB plate. Especially, for the specimens treated with $PIPEABPM^{n+}$ by reducing the smoke production rate except 2nd-smoke production rate (2nd-SPR), (0.0254~0.02270) g/s treated with $PIPEABPNi^{2+}$, 2nd-SPR (0.0117~0.0146) g/s was lower than that of PIPEABP plate. Thus, It is supposed that the combustion-retardation properties were improved by the partial due to the treated $PIPEABPM^{n+}s$ in the virgin plate.

This study was performed to test the combustive properties of pinus rigida specimens treated with methylpiperazinomethyl-bis-phosphonic acid $M^{n+}$ ($PIPEABPM^{n+}$)s and methylpiperazinomethyl-bis-phosphonic acid (PIPEABP). Each pinus rigida plates were painted three times with 15 wt% $PIPEABPM^{n+}s$ or PIPEABP solutions at the room temperature. After drying specimens treated with chemicals, combustive properties were examined by the cone calorimeter (ISO 5660-1). It was indicated that the speed to peak mass loss rate ($MLR_{peak}$), (0.104~0.121) g/s for specimens treated with $PIPEABPM^{n+}s$ was lower than that of PIPEABP plate. In addition, the total smoke release rate (TSRR), $(224.4{\sim}484.0)m^2/m^2$ for $PIPEABPM^{n+}s$ treated specimens except specimen treated with PIPEABPAl3+ and $CO_{mean}$ production (0.0537~0.0628) kg/kg was smaller than that of PIPEABP plate. In particular, for the specimens treated with $PIPEABPM^{n+}$ by reducing the smoke production rate, the second-smoke production rate (2nd-SPR) $(0.0117{\sim}0.0146)m^2/s$ was lower than that of PIPEABP plate. It can thus be concluded that combustion-retardation properties of the treated $PIPEABPM^{n+}s$ were partially improved compared to those of the virgin plate.
