Product Features
Refractive index 2.37:
The refractive index is an important parameter of optical materials. The refractive index of zinc sulfide is 2.37, which is at a relatively high level. This enables it to control the propagation and reflection of light well in optical coatings, which is very beneficial for the preparation of optical films such as high-reflective films and spectroscopic films, and can more effectively realize the functions of light reflection, refraction and beam splitting.
Good environmental stability:
Zinc sulfide is stable in dry air, is not easy to react chemically with oxygen, moisture, etc. in the air, and has good chemical stability. This enables zinc sulfide coatings to maintain long-term stability and reliability under different environmental conditions, extending the service life of optical components.
Wide light transmission range:
The transparent band range of zinc sulfide is relatively wide, usually between 0.35~14.5μm, and has good transmittance in the visible, near-infrared and mid-to-far infrared bands.
Low Mohs hardness:
Mohs hardness 3 belongs to a lower hardness level. This allows zinc sulfide to play an anti-wear role during processing.
Application
Ambition Material's Optical Coating Zinc Sulfide can be applied to optical materials, coating materials, etc. It is an infrared optical material with excellent performance, which can be used to manufacture infrared windows and hoods in the military. It is also used in the manufacture of optical coating and laser coating anti-counterfeiting labels, mainly anti-counterfeiting labels on banknotes, ID cards, passports, and laser anti-counterfeiting labels on the outer packaging of cigarettes, alcohol, and medicines. The zinc sulfide coating with Optical Coating Zinc Sulfide not only has a metallic luster, but also can produce a strong high-brightness colorful light pattern effect under light irradiation, significantly improving the grade of printed materials such as cigarette boxes, daily chemical product packaging, food packaging and gift boxes. It is also used to make luminous powder, mainly used for luminous signs such as fire evacuation signs and highway signs.
Production Technology
Ambition Material uses zinc sulfate and sodium sulfide as raw materials to react and synthesize zinc sulfide, and then goes through filter pressing and dehydration, flash drying, high-temperature calcination, crushing and packaging to complete the production process of zinc sulfide.
ZnSO4+Na2S =ZnS↓+Na2SO4
Packaging
25 kg/bag. In order to obtain the best possible results, we recommend that the products be stored in a normal temperature, dry and moderate air humidity environment, and the products should be kept unstacked and used within 12 months.
