Under the spread of the new crown epidemic, after Americans experienced life and death, they set off the largest "resignation wave" in history, and the number of resignations broke the highest record since statistics began in 2000. Since April this year, more than 4 million people in the United States have voluntarily resigned each month. In August, the number of resignations exceeded 4.27 million, and in November, it rose to 4.4 million. The operation of society is linked. The large number of departures in the United States has led to a large shortage of labor; and the shortage of a large number of labor has directly led to the supply chain crisis in the United States; the supply chain crisis has directly affected prices and prices in the United States. The economy has a direct effect on people's lives.
The economic downturn will affect the market demand for Zinc Sulfide ZnS.
Overview of Zinc Sulfide ZnS power
Zinc sulfide ZnS is a white to off-white or light yellow powder, which becomes darker when exposed to light, stable in dry air, and gradually oxidized to zinc sulfate when stored for a long time in humid air or containing water. Soluble in dilute inorganic acid, soluble in alkali, insoluble in water. Relative density 3.98 (alpha type), (d25) 4.102 (beta type). irritating.
Is zinc sulfide fluorescent or phosphorescent?
Zinc sulfide ZnS is one of the most common phosphorescent materials. Phosphorescence is a special type of photoluminescence. Unlike fluorescent substances, phosphorescent materials emit absorbed energy immediately.
Zinc sulfide ZnS is white or slightly yellow powder. Turns into crystals when burned in H2S gas. Its α variant is a colorless hexagonal crystal with a density of 3.98g/cm3 and a melting point of 1700°C. Its beta variant is a colorless cubic crystal with a density of 4.102 g/cm3, which transforms to the alpha form at 1020°C. Zinc sulfide ZnS is present in sphalerite. Insoluble in water, soluble in acid. See the daylight dim.
Zinc sulfide ZnS is converted to zinc sulfate in humid air for a long time. It is generally derived from the action of hydrogen sulfide and zinc salt solution. If a small amount of Cu, Mn, and Ag are added to the crystalline ZnS as activators, different colors of fluorescence can be emitted after being illuminated. Zinc sulfide ZnS can be used as analytical reagents and coatings. Can be used to make paints, opaque glass, rubber, plastics and phosphors.
Application of zinc sulfide ZnS power
Zinc sulfide ZnS is often made from scrap and used for other purposes. Typical sources include smelters, slags, and pickling liquors. It is also a by-product of ammonia's methane synthesis, where zinc oxide is used to remove hydrogen sulfide impurities from natural gas.
High-purity crystalline zinc sulfide powder is an important basic material, which is widely used in civil, military, aerospace and other high-tech fields. It is also an extremely important window material for medium and long-wave far-infrared precision guidance and far-infrared imaging, especially in frontier technology fields such as national defense and military. The applications of zinc sulfide are as follows: Luminescent material.
Zinc sulfide ZnS, with a small amount of a suitable activator, is highly phosphorescent and is currently used in a variety of applications from cathode ray tubes to X-ray screens to glow in dark products. When silver is used as the activator, the resulting color is bright blue with a maximum wavelength of 450 nm. The use of manganese produces a red-orange color around 590 nm. Copper glows for a long time and has the deep green glow we are familiar with. Copper-doped zinc sulfide ("ZnS+Cu") is also used in electroluminescent panels. It also exhibits phosphorescence due to impurities in blue or ultraviolet light.
Zinc sulfide ZnS is also used as an infrared optical material, which transmits from visible wavelengths to just over 12 microns. It can be used as the plane of an optical window or the shape of a lens. It is made of hydrogen sulfide gas and zinc vapor microchips and is sold as FLIR grade (forward looking infrared), in which zinc sulfide is creamy yellow and opaque. When hot isostatic pressing (HIPed), the material can be transformed into a transparent water form known as Cleartran (trademark), an early commercial form sold as Irtran-2, but this name is now obsolete.

Since February, gold has enjoyed a smooth upward run on the back of surging US inflation and the brewing of war. While expectations of rate rises have also risen in tandem over this period, gold had been largely pre-priced and the underlying driver of tightening expectations had come from inflation continuing to rise to record highs. The risk aversion caused by the continued tension in the war also provided an important short-term support for gold. This will have a certain impact on the price of the Zinc Sulfide ZnS and the market of the Zinc Sulfide ZnS.
