Abstract

In this study, an outstanding anion exchange chemical filter was prepared for acidic gas removal. Commercial anion exchange resin was attached to polyurethane (PU) foam by using different types of pressure sensitive adhesive (PSA). The water and chemical resistance and also adhesive elongation were investigated. Also, the behavior of HCl and HF adsorption was evaluated as functions of the initial concentration and flow rate. ATE-701, AT-4000C and HCA-1000 showed 900, 1,500% and 2,400% of the elongation, respectively. It was confirmed that the desorption ratio of HCA-1000 was less than 6% and had excellent durability in water and chemical resistance tests. The adsorption occurred faster as the concentration and flow rate of HCl and HF increased. But 100% adsorption equilibrium occurred after 110 minutes, regardless of the concentration and flow rate. In addition, SEM morphology showed that the adhesive was uniformly dispersed, while the porous structure of the ion exchange resin was maintained, and the chemical filter exhibited excellent durability for the adsorption/desorption process.

본 연구는 산성유해가스 제거를 위한 고효율 음이온교환 복합 폼 화학필터를 제조하기 위하여 폴리우레탄(PU) foam에 다른 종류의 PSA를 사용하여 상용이온교환수지를 부착하여 제조, 이의 내수성, 내화학성, 접착신율, 농도와 유속에 따른 HCl과 HF의 흡착특성에 관하여 연구하였다. 그 결과 접착신율은 ATE-701은 900%, AT-4000C는 1,500%, HCA-1000는 2,400%이며, 내수성 및 내화학성평가에서 HCA-1000의 탈리율이 6% 미만으로 우수한 내구성을 가짐을 확인하였다. HCl, HF의 농도와 유속이 증가함에 따라 흡착이 빠르게 일어났으며 유속과 농도에 관계없이 110 min 이후 100% 흡착파과평형이 일어남을 확인할 수 있었다. 또한 SEM Morphology 관찰 결과 점착제가 고르게 분산되어 있고 이온교환수지의 다공구조가 유지되었으며, 흡-탈착 공정에서 성능저하가 없는 것으로 보아 내구성이 있음을 확인하였다.
