Abstract

전해시험기는 금속소재와 도막으로 된 시험체의 내식시험에 사용되는 것인데, 시힘중에 발생하는 염소가스에 의한 폐해를 억제할 수 있도록 구성되어 있다.
전해시험기는 시험체를 담그기 위하여 NaCl 수용액을 저류하는 전해조와, NaCl 수용액속에 담그어진 전극과. 그 전극 및 시험체 사이에 통전하는 직류전원과, NaCl 수용액의 전기분해에 따라 발생한 염소가스를 NaCl 수용액중에서 그 NaCl 수용액과 함께 포집하는 염소가스 처리장치를 구비하고 있다. 그 염소가스 처리장치는 처리관로와, 그 처리관로에 설치된 흡입펌프 및 염소가스 정화부재를 가진다.
