도 1는 유리섬유 시트를 사용할 때의 본 발명에 따른 나노하이브리드 기반의 재생 가능한 에어필터 및 그 제조방법을 흐름도로 나타낸 것이고, 도 2는 유리섬유 분말을 사용할 때의 본 발명에 따른 나노하이브리드 기반의 재생 가능한 에어필터 및 그 제조방법을 흐름도로 나타낸 것이다.1 is a flow chart showing a nanohybrid-based renewable air filter and a manufacturing method thereof according to the present invention when a glass fiber sheet is used, and FIG. 2 is a nanohybrid-based air filter according to the present invention when glass fiber powder is used. A renewable air filter and its manufacturing method are shown in a flowchart.
이러한 본 발명에 따른 나노하이브리드 기반의 재생 가능한 에어필터 및 그 제조방법은, 첨부된 도면의 도 1과 같이 유리섬유 시트를 지지체로 사용하여 금속촉매 분산액에 담지하고 건조하고, 건조 된 유리섬유에 탄소 소스 공급과 동시에 열처리하여, 지지체인 유리섬유 상에 탄소나노구조체가 성장되도록 여재를 획득한 후, 상기 여재를 통상의 방법을 이용하여 필터로 제작하는 과정을 가진다. As shown in FIG. 1 of the accompanying drawings, the nanohybrid-based renewable air filter and method of manufacturing the same according to the present invention use a glass fiber sheet as a support, carry it in a metal catalyst dispersion, dry it, and dry the glass fiber with carbon. Heat treatment is performed at the same time as supplying the source to obtain a filter medium so that the carbon nanostructure is grown on the glass fiber as a support, and then the filter medium is fabricated into a filter using a conventional method.
도 2의 경우는 유리섬유 분말을 지지체로 사용함에 따라 시트화 단계가 필요하다.In the case of FIG. 2, a sheeting step is required as the glass fiber powder is used as a support.
1. 유리섬유 함침 단계1. Glass fiber impregnation step
유리섬유 함침 단계는, 1 도에서와 같이 유리섬유를 시트 지지체에 함침하기 위한 것이고, 2 도는 유리섬유 분말을 그 자체로 함침하는 것으로 유리섬유를 금속촉매 분산액에 함침시키는 단계이다.The glass fiber impregnation step is for impregnating the glass fiber into the sheet support as in FIG. 1, and in FIG. 2, the glass fiber powder itself is impregnated and the glass fiber is impregnated with the metal catalyst dispersion.
이때, 금속촉매 분산액은 페로센, 코발트센, 니켈센 등의 메탈로센 1종 이상을 에탄올에 분산하여 사용하나 주로 페로센-에탄올 분산액을 사용하고 농도 0.05~5.0 mol%인 것을 사용한다. 이러한 분산액에 지지체로 사용될 유리섬유를 함침시키는 것이며, 통상 6시간 동안 함침한다.At this time, the metal catalyst dispersion is used by dispersing one or more metallocenes such as ferrocene, cobaltene, and nickelcene in ethanol, but mainly ferrocene-ethanol dispersion is used, and a concentration of 0.05 to 5.0 mol% is used. This dispersion is impregnated with glass fibers to be used as a support, and is usually impregnated for 6 hours.
2. 함침층 건조 단계2. Impregnation layer drying step
함침층 건조 단계는, 상기 유리섬유 함침 단계가 종료되어 획득된 유리섬유에 건조기로 80~100℃의 온도범위에서 건조한다. 이와 같이 한정한 이유는 서서히 상온에서 건조할 수도 있으나 빠른 건조를 하여도 영향을 미치지 않고 에탄올 성분을 증발시키는 단계이다.In the step of drying the impregnated layer, the glass fibers obtained after the step of impregnating the glass fibers are dried at a temperature range of 80 to 100° C. with a dryer. The reason for this limitation is the step of evaporating the ethanol component without affecting it even if it is dried quickly, although it can be slowly dried at room temperature.
3. 함침층 열처리 단계3. Impregnated layer heat treatment step
함침층 열처리 단계는, 함침되어 건조된 유리섬유를 석영관로 내에 위치시킨 후, 400~800℃의 온도범위에서 간접적으로 가열하는 단계이다.The impregnated layer heat treatment step is a step of indirectly heating the impregnated and dried glass fibers in a temperature range of 400 to 800° C. after placing them in a quartz tube furnace.
즉, 석영재질을 가지는 관로(파이프)에 함침되어 건조된 유리섬유를 투입하고, 관로에 직접 열을 가해 열이 직접적으로 유리섬유에 영향을 주지 않도록 간접 가열하는 것으로서, 간접 가열은 2~4시간 사이 동안 이루어진다.That is, glass fibers impregnated and dried in a conduit (pipe) having a quartz material are put in, and heat is applied directly to the conduit to indirectly heat so that the heat does not directly affect the glass fibers. The indirect heating is 2 to 4 hours. takes place during
이때, 관로내에 수소, 아세틸렌, 아르곤 가스를 혼합하여 사용한다. 탄소 소스의 공급으로 인해 탄소나노구조체를 합성하고, 합성이 종료되면 탄소 소스의 공급을 중단하고 냉각하여 여재로서 획득하는 것이다.At this time, hydrogen, acetylene, and argon gas are mixed and used in the pipeline. A carbon nanostructure is synthesized due to the supply of the carbon source, and when the synthesis is completed, the supply of the carbon source is stopped and cooled to obtain a filter medium.
본 단계에 따른 함침 건조된 유리섬유의 간접 가열 단계는 상술된 유리섬유 함침 단계나 함침층 열처리 단계와 시계열적으로 영향 받지 않고 수행되도록 한다.The indirect heating step of the impregnated and dried glass fibers according to this step is performed without being affected in time-sequentially with the above-described glass fiber impregnation step or impregnated layer heat treatment step.
이러한 유리섬유 상에 탄소나노구조체가 성장함에 따라, 추후 제작되는 에어필터에 전기를 인가하였을 때, 전기에 기인한 열에 의해 이물질을 분해시켜 재사용이 가능하도록 한다.As the carbon nanostructures grow on these glass fibers, when electricity is applied to an air filter to be manufactured later, foreign substances are decomposed by heat caused by the electricity so that they can be reused.
4. 시트화 단계4. Sheeting step
탄소나노구조체가 성장한 유리섬유 분말을 슬러리하고 분사노즐로 여재를 형성하며, 감압탈수/건조/권취 과정을 거쳐 필터화 시킬 수 있는 시트를 획득하는 단계이다.This is a step of obtaining a filterable sheet through slurry of glass fiber powder on which carbon nanostructures have grown, forming a filter medium with a spray nozzle, and dehydrating under reduced pressure/drying/winding.
5. 에어필터 획득 단계5. Acquisition of air filter
에어필터 획득 단계는, 상기 탄소나노구조체 성장 단계를 통해 획득된 여재를 이용하여 통상의 방법으로 에어필터를 획득하는 단계이다.The step of obtaining an air filter is a step of obtaining an air filter in a conventional method using the filter medium obtained through the step of growing the carbon nanostructure.
다시 말하면, 유리섬유 지지체를 시트로 하여 함침한 경우는 생산성 및 균일성을 확보하기 어렵지만 제조단계를 간소화 할 수 있어 열처리단계 후 바로 에어필터를 획득할 수 있고, 유리섬유 지지체를 분말로 할 경우 열처리 후 시트화 단계를 거친 후 에어필터를 획득하도록 하여 비록 제조단계가 늘어나기는 하지만 품질의 균일성 확보 및 대량생산이 가능한 것으로 유리섬유의 지지체를 시트로 할 것인지 분말로 할 것인지에 따라 필요에 따른 적합한 에어필터를 획득할 수 있다. In other words, when the glass fiber support is impregnated as a sheet, it is difficult to secure productivity and uniformity, but the manufacturing step can be simplified, so that an air filter can be obtained immediately after the heat treatment step, and when the glass fiber support is made into a powder, heat treatment After going through the sheeting step, an air filter is obtained. Although the manufacturing step is increased, uniformity of quality and mass production are possible. Suitable air as needed depending on whether the glass fiber support is made into a sheet or powder. filter can be obtained.
