着色探伤液是机械加工成品及半成品质量鉴定的重要材料,应用极为广泛。目前,国外品种甚多,性能差别也很大。根据使用部门的反映,认为从日本进口的着色探伤液性能较好。因此,我们解剖了该产品的化学组成,分析了它的某些理化性能指标,并用国产原料试制成功性能与之相似的三种产品。解剖分析根据日本着色探伤液的主要理化性能(见表1)及使用部门的反映,该产品具有鲜明的色泽,渗透能力强,鉴定灵敏度高,挥发性小,乳化性能良好,极易用水清洗等特点。初步推测可能由三部分组成,即颜色鲜明的染料、渗透能力较强的溶剂及乳化性能良好的表 Coloring test fluid is an important material for mechanical processing of finished products and semi-finished products quality identification, the application is extremely broad. At present, many foreign varieties, performance differences are also great. According to the reflection of the using department, it is considered that the colored detection liquid imported from Japan has better performance. Therefore, we dissected the chemical composition of the product, analyzed some of its physical and chemical properties, and made three products of similar success with the domestic raw materials. Anatomical Analysis According to the main physical and chemical properties (see Table 1) of Japan Coloring Detection Liquid and the reaction from the using department, the product has distinct color, strong penetrating ability, high identification sensitivity, low volatility, good emulsifying property and easy to be washed with water Features. Preliminary speculation may be composed of three parts, namely, brightly colored dyes, strong penetration of solvents and good emulsifying properties of the table
