About heterocyclic ultraviolet phosphors weather resistance

Many customers ask which kind of ultraviolet phosphor powder is the best and most stable. In fact, in terms of the existing known synthesis technology, heterocyclic ultraviolet phosphor is the most stable, which is a rigid structure connected by a benzene ring. Its weather resistance is the best, water resistance: level 5; Ink resistance: 5 grade; Acid resistance: 5; Alkaline resistance: level 4; Paraffin resistance: grade 5; Light resistance: ≥ grade 4 (95 hours in the sun) Generally used in [...]

Development prospect and market potential of reflective powder

Reflective powder is the production of reflective fabric, reflective film, reflective coatings, reflective signs, school bags, sea life-saving supplies the core of the new optical functional composite materials such as raw materials, it has the characteristics of regression reflection and the resulting strong regression reflection effect, without additional power supply, can be widely used in roads, ports, mines, fire and other fields, as a safety sign, is greatly improved. The following Xiaobian to introduce the development potential and prospects [...]

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: [...]

Water based paint production process related information

The basic production process of waterborne paint: the production process of waterborne paint is to put all kinds of raw materials in a certain order and disperse evenly. The production process of general latex paint includes 3 parts: (1) slurry: first of all, water, dispersant, defoaming agent, preservatives and other liquid materials into the dispersion tank, mixing evenly, in the state of mixing will be colored pigments and physical pigments in turn into, and accelerate the dispersion of 20~40; [...]

Application of photoluminescent powder proportioning

Photoluminescent powder is more and more widely used, new luminescent materials can be used in a variety of transparent or translucent media, such as plastic, silicone rubber, POLY resin, paint, glaze, ink, chemical fiber, etc. It can be used to prepare toys, craft ornaments, silica gel bracelets, artificial flowers, display objects at night and so on. The following is the application of Photoluminescent powder proportioning. 1, the proportion of Photoluminescent powder and plastic material is generally in 2%-10%. According to [...]

The reason why the brightness of the luminous powder is not high after injection molding

Luminous powder is a kind of luminous pigment that can emit light automatically. It can be used in various plastic products, clothing printing, chemical fibers, and indicator signs, etc. However, some customers reported that after buying the luminous powder and using it on the plastic, they found that the brightness of the luminous powder was not as good as expected, and even the situation was not bright. Today, I will analyze the reasons why the brightness of the luminous [...]
