The present invention is a standard setting for development of a new corrosion inhibitor to be developed in Korea, which is a member of an anti-corrosion expert training policy, and its application for a purpose of preventing corrosion of sprinkler pipes. In addition, the present new invention relates to the new corrosion inhibitor applied as a core technology of a sprinkler piping method planned maintenance system, which is a system maintenance technology developed in consideration of a domestic situation. A name of the new invention is the water-soluble silicic acid-based corrosion inhibitor for the wet sprinkler piping.

Description

습식 스프링클러 배관 방식용 수용성 규산계 부식억제제{Water soluble silica inhibitor for wet type sprinkler piping system corrosion protection}Water soluble silica inhibitor for wet type sprinkler piping system corrosion protection

본 발명은 소방설비 습식 스프링클러 배관 계통의 부식방지를 위한 친환경 규산계 수용성 부식억제제의 신규물질 개발과 적용에 관한 것이다.The present invention relates to the development and application of a new material of an eco-friendly silicic acid-based water-soluble corrosion inhibitor for corrosion prevention of wet sprinkler piping systems in firefighting equipment.

국내의 기존 소방설비 스프링클러 시스템은 미국의 소방협회(NFPA)규정을 근거한 국내 화재 안전기준(NFSC)에 따라 일정규모 이상 건축물의 화제 예방목적으로 설치하도록 하고 있으나, 부식에 대한 사회의 인식부족으로 방식분야 교육 및 전문기술자 양성정책 부재를 이유로 국내의 NFSC에선 지금까지도 배관의 부식 문제가 간과되고 있는 실정이다.Existing firefighting equipment sprinkler systems in Korea are to be installed for the purpose of preventing fires in buildings over a certain size in accordance with the National Fire Safety Standards (NFSC) based on the National Fire Protection Association (NFPA) regulations of the United States. Due to the lack of field education and a policy to nurture specialists, the domestic NFSC still overlooks the problem of pipe corrosion.

즉 미국의 NFPA에선 경제성을 고려, 염가의 강관(steel pipe)을 적용하면서 강의 부식성을 감안 배관의 부식방지를 위해 주기적으로 진단하고, 방식처리 하는 규정을 운영하고 있는데 반해, 국내의 NFSC에선 지금까지도 제외해 옴으로서, 강관의 부식문제가 기능저하에 직, 간접적 영향을 미치고 있는 것으로 지적되고 있다. 본 발명은 국내외의 기술자료를 종합 비교 분석하여, 국내 실정에 맞춘 고성능의 배관 방식기술 개발의 일환으로 친환경, 고기능 수용성 부식억제제 신규 개발과 적용에 관한 것이다.In other words, the NFPA of the United States operates a regulation that periodically diagnoses and treats corrosion in order to prevent corrosion of the pipe in consideration of the corrosiveness of steel while applying a cheap steel pipe in consideration of economic feasibility. It is pointed out that the corrosion problem of the steel pipe directly or indirectly affects the deterioration of the function. The present invention relates to a new development and application of an eco-friendly, high-functional water-soluble corrosion inhibitor as part of the development of high-performance piping corrosion protection technology tailored to the domestic situation by comprehensively comparing and analyzing domestic and foreign technical data.
