Method for making reflective powder in reflective glass

Reflective powder is made of a kind of glass beads powder material production, China is one of the big reflective powder production, because reflective powder energy consumption is more serious, can use is reflective clothing, this is the official statement, the most common is at night or on the highway sanitation workers reflective clothing, Today we are going to share about the manufacturing method used in reflective glass: A. Mix the glue in a certain proportion. B, after mixing the two, [...]

How to solve the dark phenomenon of luminous powder in the process of injection molding

Noctilucent plastic masterbatch is a kind of plastic masterbatch with self-luminescence function. Noctilucent plastic masterbatch is made of noctilucent powder and transparent resin after deep processing. It can be used directly or mixed with other similar plastics. If the noctilucent powder is directly added to ordinary plastic products, it is easy to make the product black and discolored. Noctilucent plastic masterbatch can solve the phenomenon of noctilucent powder blackening and uneven dispersion in the plastic production process. Noctilucent powder [...]

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: [...]
