Description

이온교환섬유와 이온교환수지를 결합시킨 복합이온교환필터와 이를 이용한 케미칼 필터{Ion exchange filter material binding ion exchange fiber and ion exchange resin} Ion exchange filter combined with ion exchange fiber and ion exchange resin and chemical filter using same {ion exchange filter material binding ion exchange fiber and ion exchange resin}

본 발명은 이온교환섬유와 이온교환수지를 결합시킨 복합이온교환필터와 이를 이용한 케미칼 필터에 관한 것으로, 보다 자세하게는 반도체 제조 공정의 클린룸에 존재하는 산성, 알카리성 등의 이온가스들을 제거할 수 있는 케미컬 필터의 소재인 복합이온교환필터와 이를 사용한 케미컬필터에 관한 것이다. The present invention relates to a composite ion exchange filter combining ion exchange fibers and an ion exchange resin and a chemical filter using the same. More particularly, the present invention can remove acidic and alkaline ion gases present in a clean room of a semiconductor manufacturing process. The present invention relates to a composite ion exchange filter that is a material of a chemical filter and a chemical filter using the same.

현재 클린룸에 존재하는 미량의 유해이온가스를 제거하는 소재나 필터는 보통 첨착활성탄, 이온교환섬유, 이온교환수지등들 이용하고 있다. 그 중에서 첨착활성탄으로 유해가스를 제거하는 방식은 일반활성탄에 산을 이용하여 첨착시키고 첨착된 활성탄에 의해 유해이온가스를 화학적으로 결합시켜 제거하는 방법이다. 하지만 첨착활성탄 방식의 단점은 필터가 무겁다는 것과 차압으로 인해 풍량이 큰 곳에 설치하는데 한계가 있다. 이러한 차압문제 해결을 위해 우레탄 폼에 첨착활성탄을 부착한 필터가 사용되고 있지만 차압문제를 해결한 대신 첨착활성탄에 비해 흡착용량이 적어지는 문제가발생된다. Currently, materials and filters that remove trace amounts of harmful ion gases present in clean rooms are usually using impregnated activated carbon, ion exchange fibers, or ion exchange resins. Among them, the method of removing harmful gas with impregnated activated carbon is a method of impregnating normal activated carbon with an acid and chemically combining the harmful ion gas with the impregnated activated carbon. However, the disadvantage of the impregnated activated carbon method is that the filter is heavy and due to the differential pressure there is a limit to the installation in a large air volume. In order to solve the differential pressure problem, a filter having an impregnated activated carbon attached to a urethane foam is used, but instead of solving the differential pressure problem, a problem that the adsorption capacity is lowered than that of the impregnated activated carbon is generated.

유해이온가스를 제거하는 또 다른 방식으로는 이온교환부직포를 사용하고 있으나 이러한 케미칼 필터는 필터의 무게가 가볍고, 차압이 적게 걸리는 반면에 이온교환부직포가 고가이기 때문에 케미칼 필터의 비용이 높으며, 이온교환부직포의 이온교환능력이 제한적이라는 단점이 있다. Another method of removing harmful ion gas is ion exchange nonwoven fabric. However, these chemical filters are light in weight, low in differential pressure, and high in ion exchange nonwoven fabric. There is a disadvantage that the ion exchange capacity of the nonwoven fabric is limited.

또 다른 방식으로는 이온교환수지를 폴리우레탄폼에 부착한 이온교환필터가 사용되고 있다. 이 경우 차압이나 이온교환용량은 어느 정도 확보하였지만 이온교환수지를 우레탄 폼(foam)에 접착제로 부착하였기 때문에 이동, 설치, 사용 시간, 빠른 풍속, 접착제의 노화 등으로 인해 부착되었던 이온교환수지의 일부가 떨어지는 문제가 발생한다. 또한 이온교환용량을 더 이상 높이는 데는 어느 정도 한계가 있는 것으로 알려져 있다. As another method, an ion exchange filter having an ion exchange resin attached to a polyurethane foam is used. In this case, the differential pressure or ion exchange capacity was secured to some extent, but since the ion exchange resin was attached to the urethane foam with an adhesive, a part of the ion exchange resin attached due to movement, installation, use time, fast wind speed, and aging of the adhesive Falling problem occurs. It is also known that there is some limit to further increasing the ion exchange capacity.

위와 같은 문제를 해결하기 위해서 필터 차압이 적게 걸리고 이온교환능력이 큰 필터소재와 그 소재를 이용한 케미컬필터를 만드는 것이 가장 중요한 점이다. In order to solve the above problems, it is most important to make a filter material with a low filter differential pressure and a large ion exchange capacity and a chemical filter using the material.

본 발명은 차압이 작으면서 이온교환능력을 크게 하여 사용기간을 증대시키면서 유해이온가스에 대한 제거 효율을 크게 할 수 있는 복합이온교환 필터와 필터 유니트를 제공하는 것을 목적으로 하며, 구체적으로는 이온교환섬유와 이온교환수지를 조합한 형태로서 이온교환수지가 이온교환섬유가 내부에 충진돼어 있는 부직포나 직포 형태로서 이온교환수지와 이온교환섬유가 동시에 이온성 유해 가스를 화학적으로 제거할 수 있도록 한 것이다. It is an object of the present invention to provide a complex ion exchange filter and a filter unit which can increase the removal efficiency of harmful ion gas while increasing the service life by increasing the ion exchange capacity while reducing the differential pressure. It is a combination of fiber and ion exchange resin. It is a nonwoven fabric or woven fabric in which ion exchange fiber is filled, so that ion exchange resin and ion exchange fiber can remove ionic harmful gas at the same time. .

본 발명자는 이온교환섬유를 가지고 연구한 결과 니들 펀칭하여 이온교환부직포를 만들고, 이를 이용하여 이온교환필터를 만들어 이온교환능력을 향상시키기 위한 방법을 연구하는 중 다음과 같은 발명에 도달하게 되었다.  The present inventors have researched with ion-exchanged fibers, and as a result of researching a method for improving ion-exchange ability by making needle-exchanged non-woven fabrics by using needle punching and making ion-exchange filters using the same.

상기 목적을 달성하기 위한 본 발명은 먼저 이온교환부직포 위에 이온교환섬유로 웹(web)을 만들고 그 위에 이온교환수지를 골고루 뿌려 넣은 후 이온교환부직포를 그 위에 올려놓고 니들펀칭을 이용하여 부직포형태의 복합이온교환필터를 제공한다.The present invention for achieving the above object is first made a web (web) with ion exchange fibers on the ion exchange nonwoven fabric and evenly sprayed on the ion exchange resin thereon and then placed on the ion exchange nonwoven fabric thereon using a needle punching It provides a composite ion exchange filter.

또한, 본 발명에서는 상기 부직포 대신에 직포를 사용한 직포형태의 복합이온교환필터를 제공한다.The present invention also provides a composite ion exchange filter in the form of a woven fabric using a woven fabric instead of the nonwoven fabric.

본 발명에서는 상기 이온교환섬유와 이온교환수지가 각각 양이온교환기 또는 음이온교환기를 가진 것 어느 것이라도 사용할 수 있으며, 양자를 서로 조합하여 사용할 수 도 있다.In the present invention, any one of the ion exchange fiber and the ion exchange resin having a cation exchange group or an anion exchange group may be used, or both may be used in combination with each other.

본 발명은 상기와 같이 제조된 복합이온교환필터를 사용하여 절곡하고 그 사이에 세퍼레타를 넣어 만든 케미칼 필터를 제공한다.The present invention provides a chemical filter that is bent using a composite ion exchange filter prepared as described above and put a separator in between.

상기 본 발명의 구성에 따른 복합이온교환필터의 경우는 이온교환수지를 여러 가지 기재에 부착하는 것보다 이온교환 흡착량이 더 많다는 것이 실험 결과 나타났다. 그 이유는 이온교환수지를 다른 여재에 부착할 경우 부착하는 부분은 접착제로 인해 표면이 가려져 있어 그만큼 흡착능력이 떨어지기 때문이다. 그러나 본 발명의 구성에 따라 이온교환섬유사이에 이온교환수지를 넣는 경우는 접착에 의한 것이 아니라 이온교환섬유사이에 이온교환수지가 갇혀 있어서 표면 전체가 노출되어 있어 이온교환능력의 감소가 없다. 또 다른 작용효과로는 기재에 부착할 경우는 운반, 설치, 접착제 노화, 빠른 풍속으로 인해 이온교환수지가 떨어져 나올 수 있지만 이온교환 부직포속에 있는 이온교환수지는 이동, 설치, 풍량에 의한 이온교환수지의 탈착이 없다. 더욱이 기재에 부착한 소재는 이를 이용하여 필터를 제작하는데 여러 가지 단점이 있다. 예를 들면, 필터를 만든 다음 필터의 양쪽 면을 부직포와 알루미늄 망을 씌워서 떨어진 이온교환수지가 밖으로 떨어져 나오지 않도록 해야 하거나, 접촉에 의한 이온교환수지의 탈착을 방지하도록 되어 있다. 양쪽에 부직포를 씌우기 때문에 차압이 증가하게 되고 조심스럽게 다루지 않으면 안 된다. 하지만 본 발명은 외형 형상이나 성질이 일반 이온교환부직포와 같기 때문에 일반 이온교환부직포처럼 절곡하여 이온교환 필터를 쉽게 만들 수 있는 장점이 있다. 또한 작업이나 운반 보관 등에 전혀 영향을 받지 않기 때문에 핸들링에 유리하다. 차압 또한 일반 이온교환 부직포 수준 정도로서 크지 않고 또 쉽게 절곡하여 필터를 만들기 때문에 필터 여재를 많이 넣을 수도 있어 이온교환 흡착 능력을 최대로 할 수 있을 뿐 아니라 필요에 따라 이온교환수지나 섬유의 양을 조절하여 차압이나 이온교환양, 흡착대상 물질에 따라 수지의 종류를 정할 수 있다.In the case of the composite ion exchange filter according to the configuration of the present invention, the experimental results showed that the amount of ion exchange adsorption is larger than that of attaching the ion exchange resin to various substrates. The reason is that when the ion exchange resin is attached to other media, the surface of the attachment portion is covered by the adhesive, so that the adsorption capacity is reduced. However, when the ion exchange resin is placed between the ion exchange fibers according to the configuration of the present invention, the ion exchange resin is trapped between the ion exchange fibers rather than by adhesion, so that the entire surface is exposed and there is no decrease in the ion exchange capacity. Another effect is that the ion exchange resin in the ion exchange nonwoven fabric may fall off due to transportation, installation, adhesive aging, and high wind speed when attached to the substrate. There is no desorption. Moreover, the material attached to the substrate has various disadvantages in manufacturing the filter using the same. For example, after the filter is made, both sides of the filter should be covered with a nonwoven fabric and an aluminum mesh to prevent falling ion exchange resins from falling out or to prevent desorption of the ion exchange resins by contact. Non-woven fabric on both sides increases the differential pressure and must be handled with care. However, the present invention has an advantage that the ion exchange filter can be easily made by bending like a general ion exchange nonwoven fabric because its external shape and properties are the same as a general ion exchange nonwoven fabric. It is also advantageous for handling because it is not affected at all by work or transport storage. Differential pressure is also about the same level of general ion exchange nonwoven fabric, and it is not big and makes it easy to bend the filter, so you can put a lot of filter media to maximize the ion exchange adsorption capacity and adjust the amount of ion exchange resin or fiber as needed The type of resin can be determined according to the differential pressure, the amount of ion exchange, and the substance to be adsorbed.

이하에서는 본 발명을 첨부 도면을 참고로 보다 자세히 설명한다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

상기 본 발명에 따른 복합이온교환필터는 니들 펀치법을 사용할 경우 웹(web)을 기계적으로 결합하는 방법을 사용할 수 있다. 먼저 이온교환부직포(1)를 만들고 그 위에 이온교환섬유(2)를 카드기 또는 에어레이(Air-Laid)법에 의해 형성시켜 만든 이온교환 웹(web)(3)을 통과 시키고 이 웹(web) 위에 이온교환수지(4)를 골고루 분사한 다음 다른 카드기나 에어레이에 의해 만들어진 이온교환 웹(3)을 그 위에 놓거나 이미 만든 이온교환부직포(1)를 위에 올려놓고 니들펀칭기(Needle Loom)(5)을 통과시킬 때 니들이 붙은 침판을 상하 반복 운동시켜 2차원적인 랜덤한 섬유배열의 일부를 3차원적인 랜덤 구조로 결합시키는 것이다. 니들펀치의 동작도 상, 하 또는 상하 양 방향으로 니들이 왕복 운동하는 여러 가지 종류가 있다. 경우에 따라서는 스윗치 본딩(Stitch Bonding)식 또는 스프레이 식으로 얻은 이온교환 웹(3)에 이온교환수지(4)를 고르게 분사한 다음 니들펀칭기(5)를 통한 기계적인 결합을 가한 후에 적당한 처리를 하여 최종제품인 복합이온교환소재(6)을 얻을 수 있다. 이때 이온교환수지(4)의 양이나 두께, 이온교환섬유(2)의 양이나 두께 또는 결합정도에 따라 차압, 이온교환 흡착 능력 등을 자유롭게 조절하여 필요에 따라 여러 가지 종류의 이온교환복합소재(6)를 얻을 수 있다. 이때 이온교환수지(4)의 수분 함량은 크게 영향을 미치지 않으나 약간만 건조시켜도 큰 문제가 안 되며 이때 사용할 수지는 산이나 알카리 처리를 하여 H 나 OH 폼으로 변환시켜야 한다. 그리고 이온교환섬유와 수지를 관능기에 따라 페놀계, 아크릴계, 산성, 알카리성, 강성, 약성 등 원하는 소재를 자유롭게 선택하고 조합하여 부직포 형태로 만들 수가 있다.The composite ion exchange filter according to the present invention may use a method of mechanically coupling a web when using the needle punch method. First, an ion exchange nonwoven fabric (1) is made and the ion exchange fibers (2) formed thereon are passed through an ion exchange web (3) formed by a carding machine or an Air-Laid method. Spray the ion exchange resin (4) evenly over the top, and then place the ion exchange web (3) made by another carding machine or airlay on it, or put the already made ion exchange nonwoven fabric (1) on the needle loom ( When passing through 5), the needle plate with needles is repeatedly moved up and down to combine a part of the two-dimensional random fiber array into a three-dimensional random structure. There are also various kinds of needle punches in which needles reciprocate in up, down, or up and down directions. In some cases, ion-exchange resin (4) is evenly sprayed onto the ion-exchange web (3) obtained by the stitch bonding or spray method, and then mechanically bonded through the needle punching machine (5), followed by appropriate treatment. The composite ion exchange material 6 as a final product can be obtained. At this time, according to the amount or thickness of the ion exchange resin (4), the amount or thickness of the ion exchange fiber (2) or the degree of bonding, the differential pressure, ion exchange adsorption capacity, etc. can be freely adjusted, and various kinds of ion exchange composite materials ( 6) can be obtained. At this time, the moisture content of the ion exchange resin (4) does not significantly affect, but only a little drying is not a big problem and the resin to be used should be converted to H or OH foam by acid or alkali treatment. In addition, the ion exchange fibers and resins can be freely selected and combined into non-woven fabrics such as phenolic, acrylic, acidic, alkaline, rigid and weak according to functional groups.

예를 들면 스티렌계 강산성 이온교환섬유와 강산성이온교환수지를 결합하여 강산성이온교환부지포를 만들 수 있고, 강산성이온교환섬유와 강염기성 이온교환수지를 결합하거나 역으로 하여 산성과 알카리형 관능기를 동시에 갖는 복합이온교환소재(6)를 만들 수 있다. 반대로 강산성이온교환섬유와 약산성이온교환수지를 결합시킬 수 있고, 강염기성이온교환섬유와 약염기성이온교환수지등을 자유자재로 선택하여 부직포형 복합 이온교환 소재(도면2)를 만들 수 있다.For example, a strong acidic ion exchange resin can be made by combining styrene type strong acidic ion exchange fiber and strong acidic ion exchange resin, and the acidic and alkaline functional groups can be combined simultaneously by combining strong acidic ion exchange fiber and strong base ion exchange resin or vice versa. It is possible to make a composite ion exchange material (6) having. On the contrary, the strong acid ion exchange fiber and the weak acid ion exchange resin can be combined, and the non-woven composite ion exchange material (Fig. 2) can be made by freely selecting the strong base ion exchange fiber and the weak base ion exchange resin.

도 2는 이러한 복합이온교환필터의 구조를 확대한 것이다. 이러한 복합형이온교환소재(6)를 이용하여 기존의 헤파(HEPA)필터와 같이 세퍼레타(7) 절곡하여 필터를 제작하면 케미컬필터장치(도 3 참고)로 만들어 사용할 수 있다.2 is an enlarged structure of such a composite ion exchange filter. Using the composite ion exchange material (6) by bending the Separetta (7) like the conventional HEPA (HEPA) filter to produce a filter can be used as a chemical filter device (see Figure 3).

이하에서 본 발명의 바람직한 실시형태를 도면에 참고로 설명 한다.Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

먼저 m2 당 50-100 그램 정도의 이온교환부직포(1)를 만든다. 부직포의 두께나 무게는 만들려고 하는 복합이온교환필터소재(6)의 종류에 따라 달라질 수 있다. 여기서 소재의 두께나 차압을 조절할 수 있다. 이러한 부직포를 두 롤 준비한 다음은 한 장의 이온교환부직포(1)를 진행시키면서 그 위에 이온교환섬유(2)를 가지고 섬유상 웹을 만들고 그 웹 위에 원하는 종류의 이온교환수지(4)를 골고루 분사시킨다. 이온교환섬유(2)를 분사한 다음 그 위에 이미 준비된 이온교환부직포(1)를 놓고 니들펀칭기(5)로 보내 웹을 결속하여 부직포 형태로 만든다. 이때 필요에 따라 이온교환부직포(1)외의 이온교환웨브(3)를 일반섬유로도 사용할 수 있다. 그 다음 공정은 일반 부직포 제조공정과 동일하며 필요에 따라 이온교환섬유(2)와 이온교환수지(4)가 열에 의해 변형되지 않는 한도에서 가열하여 성형할 수도 있다.First make an ion exchange nonwoven fabric (1) of about 50-100 grams per m 2 . The thickness or weight of the nonwoven fabric may vary depending on the type of composite ion exchange filter material 6 to be made. Here you can adjust the thickness of the material or the differential pressure. After preparing two rolls of such a nonwoven fabric, a sheet of ion exchange nonwoven fabric 1 is advanced, and a fibrous web is formed with ion exchange fibers 2 thereon, and the desired type of ion exchange resin 4 is evenly sprayed on the webs. After spraying the ion exchange fibers (2) and put the already prepared ion exchange nonwoven fabric (1) on the needle punching machine (5) to bind the web to form a nonwoven fabric. At this time, the ion exchange web 3 other than the ion exchange nonwoven fabric 1 can also be used as a normal fiber as needed. The subsequent process is the same as that of the general nonwoven fabric manufacturing process, and if necessary, the ion exchange fibers 2 and the ion exchange resins 4 may be heated and molded as long as they are not deformed by heat.

상기 과정을 통해 만들어진 복합이온교환부직포(6)는 다른 일반이온교환부직포와 동일한 방법으로 케미컬필터를 제작할 수 있다. 복합이온교환필터를 절곡하여 그 사이에 세퍼레타(7)를 넣어 모양을 만들고 알루미늄이나 기타 프레임(8) 속에 넣어 필터 유니트를 제작한다.The composite ion exchange nonwoven fabric 6 made through the above process can produce a chemical filter in the same manner as other general ion exchange nonwoven fabrics. The composite ion exchange filter is bent and the separator (7) is inserted between them to form a shape, and the filter unit is manufactured by putting it in aluminum or other frame (8).

본 발명에 의한 필터장치는 유니트 당 이온교환용량을 최대로 할 수 있고 일반 부직포속에 이온교환수지를 넣어 성형한 필터의 일부 가스를 통과시키는 현상을 제거하여 유해가스의 제거효율을 높일 수 있다.The filter device according to the present invention can maximize the ion exchange capacity per unit and remove the phenomenon of passing some gas of the filter formed by inserting the ion exchange resin in a general nonwoven fabric, thereby improving the removal efficiency of harmful gases.

Hereinafter, the present invention will be described in more detail with reference to one embodiment, but the present invention is not limited thereto. Examples 1-4 Each implementation according to the type and amount of each ion exchange resin and fiber shown in Table 1 below The composite ion exchange nonwovens of Examples 1 to 4 were made to be 2.4 mm thick. As shown in Table 1, the amount of strong acidic ion exchange fibers used was 150 grams per m 2 and the amount of ion exchange resin (4) was 560 grams per m 2 . Using this composite material, an ion exchange filter of 610mm x 610mm x 150mm was produced. The area of the composite ion exchange filter material 6 required at this time was 5.6 m 2 . In other words, the ion exchange fiber took 0.84 kg, and the ion exchange resin (4) took 3.2 kg. The ion exchange capacity of the ion exchange fiber (2) was 3.0 eq / kg and the ion exchange resin (4) was 3.5 eq / kg. The ion exchange fiber (2) used here was a strong acid ion exchange fiber of our company. Resin (4) used SK1B of Samyang Corporation. For the anion exchange fiber, Samyang Corp. strongly basic ion exchange resin SA20 of 2.0 eq / kg and 2.3 eq / kg was used. The removal efficiency of ammonia was about 98.7% at 0.5 m / s. The total ion exchange capacity of this ion exchange filter was 13.5 eq / unit. The performance of this ion exchange filter was compared with the conventional filter and the results are shown in Table 2.

상기와 같이 구성되는 본 발명의 복합이온교환필터는 종래의 이온교환섬유로만 만든 부직포를 이용한 이온교환필터에 비해 압력손실은 크게 증대시키지 않으면서 필터의 수명을 크게 증대 시킬 수 있을 뿐만 아니라 이온교환수지를 폴리우레탄과 같은 기재에 접착제를 사용하여 만든 것 보다 유동성이나 성형성 등이 우수하여 원하는 필터를 자유자재로 절곡하여 이온교환부직포를 사용한 필터처럼 여러 종류의 필터를 만들 수 있다.The composite ion exchange filter of the present invention configured as described above can greatly increase the life of the filter without significantly increasing the pressure loss as compared to the ion exchange filter using a nonwoven fabric made of conventional ion exchange fibers as well as the ion exchange resin. It is superior in fluidity and formability than that made by using an adhesive on a substrate such as polyurethane, so that any type of filter can be made like a filter using an ion exchange nonwoven fabric by bending the desired filter freely.
