Abstract
본 발명은 통상의 폴리에스터 스판본드 또는 단섬유 부직포에 열엠보싱 처리를 하고, 내열발수발유성수지, 발포제, 발포안정제, 방염제, 기공형성제, 대전방지제로 배합한 혼합수용액을 일정배율로 발포시킨 다음 그 용액을 상기 부직포에 0.3~1.0mm로 편면코팅 후 건조, 큐어링(Curing)시킴으로써 내열성, 발수발유성, 제전성, 표면평활성이 우수하며 균일한 기공크기 및 고포집성능을 갖는 백필터를 제조하는 방법으로서, 본 발명의 필터는 화학, 제철, 시멘트산업 등 분체를 사용하는 모든 산업의 집진기 내에 장착하여 분체의 포집, 여과 및 이송을 시키는 여과필터로 매우 유용하다.The present invention is heat embossed to a conventional polyester spunbond or short-fiber nonwoven fabric, and the mixed aqueous solution formulated with a heat-resistant water- and oil-repellent resin, a foaming agent, a foam stabilizer, a flame retardant, a pore-forming agent, an antistatic agent and foamed at a constant rate Next, the solution is coated on the nonwoven fabric with 0.3 to 1.0 mm, and then dried and cured to obtain a bag filter having excellent heat resistance, water and oil repellency, antistatic properties, surface smoothness, and uniform pore size and high collection performance. As a manufacturing method, the filter of the present invention is very useful as a filtration filter which is installed in dust collectors of all industries using powders such as chemical, steelmaking, and cement industries to collect, filter, and transport powders.
