What is zinc sulfide? Zinc sulfideis insoluble in water and soluble in acid. It turns dark when exposed to sunlight. It is transformed into zinc sulfate after being exposed to humid air for a long time. It is generally obtained by hydrogen sulfide and zinc salt solution. If a small amount of Cu, Mn, and Ag is added to the crystal ZnS as an activator, it can emit fluorescence of different colors after being illuminated. It is used as an analytical reagent, coating, and oil making. It is particularly useful for zinc sulfide when pure white paint is required. In the coating of aerospace aircraft, the characteristics of zinc sulfide are also very useful; the ability to reflect ultraviolet light is greater than that of titanium dioxide; High temperature is more durable than titanium dioxide, and lead white is not easy to yellowing, especially for silicone and acrylic paint film; In the aerospace environment, the ratio of solar radiation absorption to infrared radiation of zinc sulfide can be kept low and stable for a long time. Most common daily paints use titanium white, and few use zinc sulfide.
The harm of zinc sulfide to human body In the human body, the zinc content is more than 1/100000. Human semen contains up to 0.2% zinc, while the visual part of the eye contains up to 4% zinc. The bone growth and sexual development of people with zinc deficiency will be affected. In the Middle East, there has been a serious zinc deficiency, resulting in extremely slow growth and sexual development of residents in the region. In addition, people with zinc deficiency often show symptoms such as poor appetite, insensitive taste, and difficulty in wound healing.
Use of zinc sulfide Zinc sulfide is mainly used in paints and plastics in chemical production. The production of zinc sulfide was first recorded in France in 1783. It has become an important pigment in paints because of its white opacity and insolubility in water, organic solvents, weak acids, and weak alkalis. Zinc sulfide has become the second most important pigment in the United States except for titanium dioxide, but it continues to enjoy an important position in European industry. As a bulk material, the melting point is 1650 ℃; Merchandise grade zinc sulfide with 98% purity has a Mohs hardness of 3.0 and a refractive index of 2.37. Because of its high refractive index and wear resistance, zinc sulfide pigment has a relatively high hiding power when coated with a thin layer on equipment, wax paper, and metal plate. Zinc sulfide is easy to disperse, not easy to agglomerate, neutral white, and has good optical properties. It is often used as a component of thermosetting plastics, thermoplastic plastics, reinforced fiberglass, flame retardant, artificial rubber, and dispersant.
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.
