在金相分析工作中,对小试样有采用铅进行镶嵌及机械镶嵌,这两种方法均产生对人体有害的气体(铅蒸气和甲醛气体),影响操作者的身体健康。我厂近几年来参考有关资料,对低熔点合金进行筛选试验,制成了无毒低熔点合金,在实际应用中取得了较满意的结果。

In the metallographic analysis work, there is a lead inlaid and mechanical inlay for the small sample, both of which produce harmful gases (lead vapor and formaldehyde gas) to the human body and affect the operator’s health. In recent years, our factory has made reference to the relevant information and conducted screening tests on low-melting-point alloys to make non-toxic low-melting-point alloys, which have achieved satisfactory results in practical applications.
