Abstract

순환수, 정지수 및 유수 중의 하나의 양태의 오수와 이의 접촉 부분에서도 충분한 항균성을 장기간에 걸쳐 보유하는 항균성 고형물, 이의 제조방법 및 이의 이용방법을 제공한다.
본 발명의 한가지 양태의 항균성 고형물은 항균 금속 이온과 금속 상태의 항균 금속을 둘다 함유함을 특징으로 한다. 일반적으로, 항균 금속 이온은 어느 농도 이상으로 피처리액에 존재하는 경우에 항균 효과는 강하지만 피처리액 속에서 신속하게 방출되어 소모되므로 이의 항균 효과는 오래 계속되지 않는다고 한다. 한편, 금속 상태의 항균 금속은 속효성이 없지만 일정한 정도의 균 억제효과를 장기간 동안 계속하여 발휘한다고 되어 있다. 따라서, 항균 금속 이온과 금속 상태의 항균 금속을 둘다 함유하는 항균성 고형물은 초기의 강한 항균성과 장기간 계속하는 균 억제성을 아울러 갖는다.
