First, long-acting luminous powder product introduction

Light-storing powder, which absorbs various visible light (sunlight, light, natural light, ultraviolet light) and stores light energy when it is not saturated. It is activated by rare earth elements in the dark to release light energy, and can be recycled indefinitely.

The long-lasting long-lasting luminous material of rare earth materials has a luminous time of more than 8 hours (recognizable by the naked eye), non-toxic, harmless, free of radioactive substances, harmless to the human body, and has good weather resistance, both indoors and outdoors. be usable. The zinc sulfide (ZnS) short-acting luminous powder can only emit about 30 minutes (light absorption is fast, the initial brightness is good, but it is dark), and it contains sulfur.

Second, long-acting luminous powder products use taboo:

1. The luminescent powder is avoided in an acidic environment (the neutralization reaction occurs with Al2O3 and acid).

2. The luminous powder avoids contact with water and is sealed as much as possible; (it will absorb moisture in the air, making the light-storing powder black and not emitting and agglomerating).

3. The luminous powder avoids contact with the metal (which will affect the unsaturated state of the storage powder and affect the luminescence).

4. Luminous powder avoids high temperature and high speed friction (which will change the existing structure of the luminous powder).

Third, the use of long-lasting luminous powder products:

1. Injection molding: firstly weigh the storage powder according to the ratio, add appropriate amount of paraffin oil (diffuse oil can be), adjust into a paste, and then pour into the well-known rubber and stir well to produce. The materials that can be injected are: PP, PE, PVC, PU, PS, ABS, TPR, EVA, PMMA, nylon, etc. The more transparent the plastic material, the better the luminous effect. If you add the toner as much as possible, use less fluorescent powder, and add as little as possible;

2. Adjusting the ink: It is said that the luminescent material, transparent varnish and related additives can be fully stirred evenly (what varnish, what additives are different).

Fourth, long-term luminous powder luminescent powder phosphor use ratio:

1. Injection molding: 4-10% luminous powder is recommended, usually 5-6% luminous powder, adjusted according to customer requirements.

More than 8% of the coarse powder has a good brightness, and the low concentration ratio uses a fine powder to have a good brightness.

2. Ink adjustment: 40-60% luminous powder is recommended, usually 50% luminous powder.

Five, long-term luminous powder adjustment ink or coating notes:

1. Mix with neutral or weakly-reducing transparent resin. The recommended ratio is 40-60%, usually 50%. The higher the ratio, the brighter the light.

2. Store in glass, ceramic or plastic containers. Stir and disperse the metal.

3. Because the luminous material is more likely to precipitate, the adjusted ink coating should be fully stirred before use.

4. The printing background color is mainly white and reflective color, which can improve the brightness and illuminating time. For example, the fluorescent color should be less than 1% of the luminous powder, and the less fluorescent pigment, the smaller the influence on the brightness.

5. To achieve good radiance, try not to use luminescent powder with too small particle size. The smaller the particle size of the luminous material, the weaker the luminance of the light. Printing or coating thickness is better than 130um (80 mesh printing twice).

Six, long-lasting luminous powder luminescent powder phosphor can be used for what

Luminous pigment luminous powder has strong application performance and can be applied to a variety of transparent or translucent media, such as plastic, silicone, rubber, POLY resin, paint, paint, ink, so it can be easily applied to the products you want to develop. The long-lasting long-lasting luminescent materials produced by Yaodexing Technology are environmentally friendly (tested by SGS and EN71-3), energy-saving and novel, and can be applied to the preparation of luminous toys, luminous crafts, luminous silicone bracelets, luminous buttons, luminous house signs, luminous Paint coatings...etc.
