Leak phosphor mainly be used in any industry



https://www.facebook.com/pages/Glow-in-the-dark-material/ First, is mainly used to bag leak detection, leak detection equipment, pipeline leaks leak, leak detection circuit is smooth, the machine detects whether the line is broken.
Second, the phosphor good heat resistance: maximum temperature of 600amp # 176C, suitable for high-temperature processing of various treatments. Good solvent resistance, acid, alkali, high stability.
Third, the phosphor of plastic injection and extrusion applications:
A. applicable to all kinds of plastics such as PE, PS, PP, ABS, acrylic, urea, melamine, polyester, resin, the fluorescent color.

B. recommended dosage of 0.05% to 0.5%, typically 0.05-0.1%

C. Mixture should add a certain percentage of additives to enhance its stability and oxidation resistance.

Fourth, the phosphor coating and screen printing ink of the application:

A. inorganic
https://www.facebook.com/pages/Glowing-rocks/ are dispersed in the paint and ink, does not dissolve in the paint and ink. Phosphor is dissolved therein.

B. can be used in oil and water-based coatings and inks it. Neutral or alkaline transparent resin (pH 5-7 mass most applicable) should be used. Recommended dosage of 2% to 3%

C. apply to all types of printing, including screen printing, gravure and letterpress printing.

D. Background printing is recommended to use a white or light-colored, color change can improve the degree of difference.

E can be mixed with dyes or pigments, with a greater variety of color variations.

F. printed material is different, you should choose a suitable substrate of paint or ink.
Five, offset or gravure colorless fluorescent ink should note the following:1. The transfer roller and the plate needs to be cleaned, using a new ink roller is more ideal, otherwise, a very small amount of colored ink also has the potential to colorless fluorescent colored ink, affect the printing quality of appearance.
2. Different papers have different effects on the colorless fluorescent colors. Since most of the surface of the paper have been processed fluorescent whitening agent, a fluorescent whitening agent in the ultraviolet lamp emits blue color light, and therefore, in the absence of brighteners paper (bond paper) sheet containing whitening agent (such as plain paper), the effect of color colorless fluorescent ink, there are some differences. Need to mention that it is precisely because of this reason, too colorless fluorescent blue ink for paper containing strong fluorescent brighteners. Otherwise, the blue fluorescence will "drown" in the blue whitener.
3. Such printing inks can be printed on non-patterned part, can also be printed on the pattern. To highlight the fluorescent effect, usually printed on the outermost layer of the pattern.
