It is the simplest and most accurate way to determine the continuation of the product, and it is a vaporization anti-rust performance measurement test method that can measure the quality of the product in a short time even during long-term storage.

기화성 방청필림이나 기화성 방청지의 기화성 방청 성능을 측정하는 방법은 여러가지 방법이 있다. NACE TEST법(NACE TM0208-2018),유럽에서 주로 많이 사용하는 TL 8105-0043 이나 TL 8105 0002, 미국국방규격( MIL spec,)에의한 ASTM B117,05534, 일본 JIS규격에 의한 (JIS Z 1535), VIA TEST.KRIEG TEST등 여러가지 방법들이 사용되고 있으나 대부분의 실험방법이 24시간 이상의 긴 측정시간과 그에 적합한 측정장비와 기구들을 필요로 하므로 빠른 시간에 품질유지를 위한 측정방법으로는 불편함이 많이 있고 특히 측정방법에 따라 KRIEG TEST,VIA TEST등은 실험오차가 크기 때문에 2회내지 3회 반복 실험하여 결과치를 도출하는 상황이다.또한 ASTM B117에 따른 염소분무 실험의 경우 고가의 실험방비가 필요하며 실험기간도 최소 7일 이상 걸리는 단점이 있다.There are various methods for measuring the vaporization rust prevention performance of vaporization rust preventive film or vaporizable rust preventive paper. NACE TEST method (NACE TM0208-2018), TL 8105-0043 or TL 8105 0002, which are mainly used in Europe, ASTM B117,05534 according to the US defense standard (MIL spec,), according to the Japanese JIS standard (JIS Z 1535) Various methods such as , VIA TEST.KRIEG TEST are used, but most of the experimental methods require a long measurement time of more than 24 hours and appropriate measuring equipment and instruments, so there are many inconveniences as a measurement method for maintaining quality in a short time. In particular, depending on the measurement method, KRIEG TEST, VIA TEST, etc. have a large experimental error, so the result is derived by repeating the experiment 2 to 3 times. In addition, in the case of the chlorine spray experiment according to ASTM B117, expensive experimental protection is required and the experiment It also has the disadvantage that it takes at least 7 days or more.

기존의 기화성 방청력을 실험하는 대부분의 실험방법은 24시간 이상의 긴 측정시간과 그에 적합한 측정장비와 기구들을 필요로 하므로 빠른 시간에 품질유지를 위한 측정방법으로는 불편함이 많이 있고 특히 측정방법에 따라 KRIEG TEST,VIA TEST등은 실험오차가 크기 때문에 2회내지 3회 반복 실험하여 결과치를 도출하는 상황이다.또한 ASTM B117에 따른 염소분무 실험의 경우 고가의 실험방비가 필요하며 실험기간도 최소 7일 이상 걸리는 단점이 있어 보다 간편하고 경제적인 실험기구와 실험측정시간을 단축함으로 빠른시간내에 기화성 방청력을 실험 할 수 있는 측정법이 요구되는 실정이다.Most of the existing test methods for testing vaporization rust prevention power require a long measurement time of 24 hours or more and appropriate measuring equipment and instruments, so there are many inconveniences as a measuring method for maintaining quality in a short time, especially in the measuring method. Accordingly, KRIEG TEST, VIA TEST, etc. have a large experimental error, so the result is obtained by repeating the experiment 2 to 3 times. In addition, in the case of the chlorine spray experiment according to ASTM B117, expensive experimental protection is required and the experiment period is at least 7 Since it has the disadvantage of taking more than one day, a more convenient and economical experimental apparatus and a measuring method that can test the vaporization rust prevention power in a short time by shortening the experimental measurement time are required.

단위공간에서 기화성 방청 필림이나 기화성 방청지의 기화성분의 기화력을 적정온도에서 빠른 시간 내에 극대화시켜 발청 조건을 극대화시킨 가운데 발청 조건을 최대화시켜 발청 여부를 측정할 수 있도록 하여 측정장비의 단순화와 측정시간의 최소화를 통해 기화성 방청력을 측정할 수 있는 실험방법을 찾기 위해 본 기화성 방청력 측정방법은 1000ml 삼각플라스크에 측정샘플 및 금속시편을 장착하여 오븐 온도 섭씨 50도에서 1시간 동안 측정샘플속의 기화성방청물질의 기화를 극대화시키는 과정 (S10) 다시 실온(섭씨23+/-2도)로 50분간 냉각후 글리세린과 증류수를 1:2로 섞은 용액 10ml를 삼각플라스크에 주입하는 단계(S20) 다시 섭씨 50도의 오븐에서 40분간 가열하여 녹이 발생할 수 있는 악조건을 만들어 발청시키는 단계(S30) 녹 발생여부를 판단하는 발청 여부 판단 단계 (S40)로 구성되어있다. 이때 금속시편은 DIN EN 10025를 사용하였으며 측정 기화성 방청필림이나 기화성 방청지는 2.5cm X 15cm 크기로 사용하였다.It maximizes the rust prevention condition by maximizing the vaporization power of the vaporization component of the vaporizable rust preventive film or vaporizable rust preventive paper at an appropriate temperature in a short time in a unit space. In order to find an experimental method that can measure vaporizing rust preventive power by minimizing Process of maximizing vaporization of material (S10) After cooling to room temperature (23+/-2 degrees Celsius) for 50 minutes, injecting 10 ml of a 1:2 solution of glycerin and distilled water into the Erlenmeyer flask (S20) again at 50 degrees Celsius It consists of a rust prevention step (S30) of determining whether rust occurs by heating in the oven of the figure for 40 minutes to create an adverse condition that rust can occur (S40). At this time, DIN EN 10025 was used for the metal specimen, and the measured vaporization anti-rust film or vaporizable anti-rust paper was used in the size of 2.5cm X 15cm.

본 발명에 의한 기화성 방청필림이나 기화성 방청지의 기화성 방청력의 측정방법은 섭씨 50도의 온도에서 삼각플라스크 내부에 기화성 입자의 기화농도를 극대화 시킬 수 있도록 1시간동안 가열함으로써 금속입자에 기화성 방청입자가 충분히 장착될 수 있도록 하였다.The method of measuring the vaporizable rust preventive power of vaporizable rust preventive film or vaporizable rust preventive paper according to the present invention is heated for 1 hour to maximize the vaporization concentration of vaporizable particles inside the Erlenmeyer flask at a temperature of 50 degrees Celsius. allowed to be installed.

또한 실온에서 냉각후 삼각플라스크 내부의 수분을 90%이상 유지할 수 있도록 글리세린과 증류수를 1:2의 비율로 혼합한 혼합액을 넣으므로 고온 다습한 환경을 만들어 녹이 발생할 수 있는 최고의 조건을 형성 시킴으로서 금속표면에 발성이 쉽게 생기는 조건 속에서도 기화성 방청필림이나 기화성 방청지가 기화성 방청력을 발휘할수 있는 조건을 설정 하였다. 수분 90%이상이고 온도가 50도 환경하에서 탄소함유량이 많은 DIN EN 10025금속시편은 통상 20분정도면 발청이 일어남으로 측정 시간을 40분으로 정하여 기화성 방청필림이나 방청지의 기화성 방청력을 측정할수 있게 안정성을 높였다.In addition, after cooling at room temperature, a mixed solution of glycerin and distilled water in a ratio of 1:2 is added to maintain 90% or more of the moisture inside the Erlenmeyer flask, so it creates a high-temperature and high-humidity environment to form the best conditions for rust to occur. Conditions were set that vaporizable rust preventive film or vaporizable rust preventive paper could exhibit vaporizable rust preventive power even under the condition that vocalization easily occurs. In a DIN EN 10025 metal specimen with more than 90% moisture and a high carbon content in an environment of 50 degrees Celsius, rust occurs in about 20 minutes. increased stability.
