国内大多数工厂,一般所采用的萤光探伤方法,是以15%的航空滑油溶解于85%的煤油中作为萤光液,以干粉法进行显示,灵敏度较低(0.01～0.02毫米)。这种方法,对质量要求高的产品例如要发现0.005毫米宽微小裂纹,就满足不了要求。因此,我们进行了有关提高萤光探伤灵敏度的试验研究。影响萤光探伤灵敏度的因素很多,但最主要的是萤光液,所以我们重点进行了高灵敏度的萤光液的配制及其性能测定方法,以及改进显示方法和操作规程等试验工作,终于试制成功一种原料立足于国内,成本 Most domestic factories, the commonly used fluorescent detection method, is 15% of aviation lubricants dissolved in 85% of the kerosene as a fluorescent liquid, the dry powder method for display, the sensitivity is low (0.01 ~ 0.02 mm). This method, for high quality products, for example, to find 0.005 mm wide cracks, can not meet the requirements. Therefore, we conducted an experimental study on improving the sensitivity of fluorescent detection. Fluorescent detection sensitivity affect many factors, but the most important is the fluorescent liquid, so we focused on the preparation of highly sensitive fluorescent liquid and its performance measurement methods, as well as improved display methods and procedures and other experimental work, and finally trial A successful raw materials based on domestic costs
