福州大学召开铝硅合金无毒快速 变质剂技术鉴定会 为了消除铝硅合金以NaF为主的多元变质剂对环境污染的有害影响,福州大学铸造教研室从1978年开始进行了无毒变质剂的研制,经过大量的实验室试验和半生产性试验,于80年2月获得成功。技术鉴定会于1980年9月5日～8日在福州大学召开,全国16个单位25名代表出席了会议。会议认为:“无毒快速变质剂”的研制成功是解决铝硅合金以NaF为主的多元变质剂对环境污染有害影响的一种新方
Fuzhou University held a non-toxic Al-Si alloy rapid metamorphic technical appraisal In order to eliminate Al-Si alloy to NaF-based multiple modifiers on the harmful effects of environmental pollution, Fuzhou University Foundry Teaching Room from 1978 on the development of non-toxic modifier After a large number of laboratory tests and semi-productive tests, in February 1980 was successful. Technical appraisal meeting was held in Fuzhou University from September 5 to 8, 1980, and 25 representatives from 16 units attended the meeting. The meeting said: “The development of” non-toxic rapid deterioration agent "is to solve the aluminum-silicon alloy to NaF-based multi-modifier on the harmful effects of environmental pollution, a new party
