A study on the Reduction of Scattering of Polyurea Coating for Waterproofing and Anti-Corrosion by Installing Air Jet Nozzle

에어분사구 설치에 따른 폴리우레아 도막 방수·방식재의 비산 발생 저감에 관한 연구

This study discusses the development of waterproofing layer jet-spray nozzle that forms a three-dimensional air cell. This nozzle has an air flow generation mechanism in the air groove of the attachment cell part located at the end of the injection nozzle. Since the air grooves also function as an air curtain, the airborne particles generated when the waterproof material is sprayed is effectively blocked. In the past, spraying of the waterproof material through the high pressure was possible, but this technology allows stable injection due to the static agitation method, and various problems caused by particle generation has been (damages to neighboring areas, economic loss, etc.) minimized.
