一九八三年,我院有五项应用科研成果通过技术鉴定,它反映了我院广大教师工程技术人员在教学科研方面的新成就。化学教研室凌藻、杨焕章、姚志信等同志研制的“275系列活性助焊剂”和“BY—去铜水(去锈、防锈液”)。这两项成果均已在生产中应用,并获得很好的评价。“275系列活性助焊剂”,是一种用于电子工业生产中的新型助焊剂。该助焊剂主要成分是松香和混合活化剂,混合添加剂等。此项成果八一年基本研制成功,经过两年时间、几十个工厂的试用,不断改进提高,至八四年四月经院级鉴定会正式鉴定通过。该助焊剂是目前国内较先进的优质焊剂,它的主要性能和技术指标达到同类进口助焊剂的水平,现已在许多工厂使用并取代进口助焊剂,为国家节约了大量外汇。
In 1983, five scientific research achievements of our hospital passed the technical appraisal, which reflected the new achievements of the majority of teachers’ engineers and technicians in teaching and research in our hospital. Department of Chemistry Ling algae, Yang Huanzhang, Yao Zhixin and other comrades developed “275 series of active flux” and “BY- to copper water (rust, rust-proof fluid”). Both of these results have been applied in production and well received. “275 Series Active Flux” is a new type of flux used in the electronics industry. The flux is mainly composed of rosin and mixed activators, mixed additives and so on. This achievement was basically developed successfully in 1981. After two years of trial, the trial of dozens of factories continued to improve and improve. In April, 1984, the accreditation of the institutes of higher learning formally passed the examination. The flux is currently the more advanced high-quality flux, its main performance and technical indicators have reached the level of similar imported flux, is now used in many factories and replace the imported flux, saving a lot of foreign exchange.
