What is zinc sulfide? Zinc sulfide is an inorganic compound with the chemical formula of ZnS. It is a white or yellowish powder that darkens when exposed to light. It is stable in dry air and gradually oxidizes to zinc sulfate when exposed to wet air for a long time or contains water. This product has two crystal forms Α Type B zinc sulfide is a colorless hexagonal crystalline powder or white to off-white or light yellow powder. The relative density is 4.087. The melting point is 1700 ℃. The thermal conductivity is 25.1 w/(m? K). The coefficient of thermal expansion (volume) is 100 ℃, 0.163:2000 ℃, 0.395:400 ℃, 0.919.800 ℃, 2.146 Β Type B zinc sulfide is cubic crystal. White to off-white or yellow powder. Relative density 4.102, melting point l700 ℃. Thermal expansion coefficient (volume): 100 ℃, 0.156.200 ℃, 0.386; 400℃,0.898； 800 ℃, 1.996. It can be slowly oxidized to sulfate in the air. The crystal transformation temperature is 1020 ℃. It is soluble in dilute inorganic acid and insoluble in water.
Use of zinc sulfide Zinc sulfide is used to manufacture optical and laser coating anti-counterfeit marks, mainly the anti-counterfeit marks on RMB, ID cards, passports, and laser anti-counterfeit marks on the outer packaging of cigarettes, alcohol, and drugs. With the development of science and technology and improving people's living standards, anti-counterfeit technology has been widely used in various commodity circulation and has become a new industry. Due to the development of the commodity economy, Anti-counterfeiting technology is receiving more and more attention in China. Modern anti-counterfeiting technology involves many disciplines, such as physics and chemistry, including many new technologies, such as materials, optics, and information. The most widely used reflective aluminized holographic film anti-counterfeiting label was prepared using the aluminized film's high reflection and the diffraction effect of grating stripes in combination with laser holographic technology. It has been developed and applied since the middle and late 1980s; over the past ten years, its anti-counterfeiting function has been gradually updated and lost with the development of knowledge and technology. Given this situation, it is necessary to research and develop new technologies with high technological content to prepare anti-counterfeiting products that are difficult to counterfeit. It is a relatively simple and efficient method to make transparent laser holographic anti-counterfeiting films using the existing preparation facilities and technologies of the total price to replace the aluminum-coated films with high-refractive transparent media films.
Preparation of zinc sulfide The reaction of hydrogen sulfide and zinc salt solution generally obtains it. If a small amount of Cu, Mn, and Ag is added to the crystal ZnS as an activator, it can emit different fluorescence colors after illumination. It is used as an analytical reagent, paint, paint, white and opaque glass, filled with rubber and plastic, and to prepare fluorescent powder.
Price of zinc sulfide Zinc sulfide particle size and purity will affect the product's price, and the purchase volume can also affect the cost of zinc sulfide. A large amount of large amount will be lower. The price of zinc sulfide can be found on our company's official website.
