About high purity zinc sulfide luminescent powder

High purity zinc sulfide powder (≥99.99%) has the characteristics of wear resistance, high strength, excellent penetration of far infrared beam, high temperature resistance and excellent fluorescence effect, electroluminescence function. It can be widely used in aerospace, national defense, far infrared precision guidance, far infrared detection, electronic information, maritime rescue, anti-counterfeiting (RMB, ID card, trademark, etc.), large DVD disc coating materials, luminous materials and other high-end science and technology fields. In particular, it is an essential functional strategic basic material in cutting-edge science and technology fields such as aerospace and national defense.
Zinc sulfide (ZnS) is a chemically inert material with high purity, insoluble in water, moderate density and easy processing, which is widely used in the manufacture of infrared window, fairing and infrared optical elements. Like zinc selenide (ZnSe) materials, ordinary infrared grade zinc sulfide (ZnS) is also a material with good refractive index uniformity and consistency, and has good image transmission performance. The material also has a high transmittance in the mid-infrared band, but absorption and scattering are enhanced as the wavelength becomes shorter. Compared with zinc selenide (ZnSe), ordinary infrared grade zinc sulfide (ZnS) has low price, high hardness, twice the fracture strength of zinc selenide (ZnSe), and strong ability to resist harsh environment.
The material has a good transmittance from the wide band of visible light 400nm to 14um, and is an indispensable material in the imaging system for all-weather use of infrared thermal imaging. The material has a certain ability to resist laser, at the same time, has a very strong ability to resist the environment. It is mainly used in Windows on outer space equipment, and Windows and lenses in infrared thermal imaging systems

High purity industrial zinc sulfide (purity in 95% ~ 98%) powder is a non-toxic, harmless, safe and environmentally friendly green products, with non-toxic and harmless, white pigment blue phase, low wear and other characteristics, is a high-grade anti-wear agent, additives, colorants, heavy metal ion complexing agent and passivating agent. Widely used in the automotive industry, long glass fiber reinforced composite materials, brake pad friction materials, high-grade water-based coatings, automotive paint and other industries, environmental protection and purification effect, is a wide range of functional civil basic materials.

As a special intermediate chemical product, luminous material is a special pigment that absorbs and stores visible light such as solar energy or lights, and then slowly releases the light that the human eye can see in the dark, helping people find and identify these visible light in the dark, so as to achieve a special luminous effect. Its absorption-storage-luminescence cycle process can be reused indefinitely, and it is a functional material for safety and environmental protection, energy saving and emission reduction, dust removal and haze reduction.
Zinc sulfide long afterglow luminescent powder has the advantages of good water resistance, ultraviolet radiation resistance, grinding resistance, chemical stability, non-toxic and harmless, can be infinite repeated absorption and luminescence, etc., can be added to transparent materials to make luminous paint, luminous ink, luminous resin and so on. Glow-in-the-dark signs for emergency life-saving evacuation routes in densely populated areas such as large supermarkets, shopping malls, business office buildings and entertainment venues; Subway, high-speed rail, highway and other luminous traffic signs; Power systems, field work, home decoration, children’s toys, luminous crafts, etc., are widely used; The zinc sulfide long lasting luminescent powder produced by the company has passed the EU EN71 safety testing standards and obtained the export permit of the EU, which can be used for new plastic products such as clothing and children’s toys in close contact with the human body, as well as for the mark painting on large warships and ships, and for nuclear leakage detection, ship detection, weld detection, etc., all of which have the application of luminous materials.
