High-purity plasma Zinc sulfide luminescent & Fluorescence powder

Superiority:

• Fluorescence grade zinc sulfide (ZnS) powder is white to pale or light yellow powder and its color will be darker when it is exposed to light. It is stable in dry air and it will be oxidized to zinc sulfate gradually when it is exposed to light for a long time or contains water. It is soluble in dilute mineral acids and not soluble in water or aqueous alkali, and pungent. Its relative density is 3.98 (α type), (d25)4.102(β type). It is mainly used in color kinescopes, basic luminescent materials, pigments, coatings, plastics, rubbers, friction materials and other fields.

• Zinc sulfide luminescent powder is a phosphorescent luminescent material. It is faint yellow or yellow green and can be other colors accoding to the needs, such as blue,  green, yellow, orange, red and so on. ZnS noctilucent powder absorbs ligh fast (it can absorb light within 4-7 minutes to reach its stimulated saturation state); it can be stimulated by light in a short time, and exposure to irradiation for a moment can stimulate it to generate the afterglow immediately.

• High-purity plasma crystal ZnS powder is white and a high-tech product researched and developed by our company independently. The manufacturing technique has reached the international advanced level and filled the gap in the material field at home; it has broken the foreign monopoly and blockade to the product and technology and won the national invention patent. It was listed as the “National key new products” by 4 Ministries including the National Ministry of Science and Technology in 2008. It is the key basic material of aerospace and electronic information and so on.  99.99% high-purity plasma crystal ZnS powder can be widely used in aerospace, infrared, detection, electron and other industry sectors because of its wear-resisting, high-strength, excellent far infrared laser beams and so on. It provides the vital window materials of the long wave infrared precision guidance and infrared imagery for most domestic advanced science and technology models. In particular, the industrial-grade ZnS powder which has the purity of 97.0%-99.0% and the grain size of 0.3-1μm is widely used in the plastic additives for the long-glass fiber enhanced hot-melt type engineering, friction materials for the automotive brake, additives for the high-grade coatings, anti-counterfeiting for the paper currency, coating materials, anti-counterfeiting for ID cards and so on.
