Quantitative determination of physical and chemical indexes of fluorescent red powder

The quantitative determination method of fluorescent red powder is not available at present, but can be carried out according to the actual situation in future communication. Coloring power: Two test methods: (1) Visual comparison method: GB/T5211.19-88 (2) Instrumental determination method: GB/T13451.2-92. In the corresponding fluorescence intensity test method of any of the above methods, the tinting force of fixed sample color code is 100%, and 100%+-2 is used to test the tinting force value of fluorescent powder. Volatile components: ethanol water Oil absorption :31~42%/110g: [...]
