Zinc sulfide powder is an important inorganic functional powder material, which is widely used in many industrial fields such as optics, coatings, electronics, luminescent materials, and the chemical industry due to its unique optical properties, chemical stability, and excellent physical properties. Among them, luminescent zinc sulfide powder and zinc sulfide phosphorescent powder, which have been doped and modified through special processes, are the mainstream long-lasting luminescent functional powders on the market and currently the most in-demand category of zinc sulfide powder for sale. Zinc sulfide powder has the advantages of environmental protection, weather resistance, long-lasting luminescence, and strong adaptability. Unlike traditional fluorescent materials, it is one of the core materials in the modern functional powder industry.
Basic characteristics of zinc sulfide powder
Zinc sulfide powder is an inorganic compound powder composed of zinc and sulfur elements, with stable physical and chemical properties and excellent optical performance. It is one of the few industrial powder materials that can achieve spontaneous phosphorescence. Its fundamental performance determines its irreplaceable application value in the fields of functional coatings, luminescent products, and optical devices.
1. Excellent optical and luminescent properties
Pure zinc sulfide powder itself has good transparency and light reflection properties, high whiteness and good glossiness and can be used as high-quality white functional fillers. After doping with trace elements such as copper, manganese, and silver, ordinary zinc sulfide powder can be converted into luminescent zinc sulfide powder and phosphorescent zinc sulfide powder, which have the ability to absorb natural light, light, and ultraviolet energy storage, and achieve long-term delayed luminescence. This type of powder emits soft light, has uniform brightness, and has a long afterglow time. It is currently the most mainstream raw material for civilian and industrial luminous signs, and is different from short-acting fluorescent powders, with extremely high practical value.
2. Stable chemical properties
Zinc sulfide powder is chemically inert and insoluble in conventional solvents such as water and ethanol at room temperature. It is not easy to react with acid-base substances, and it has excellent antioxidant and anti-aging properties. Stored and used in a conventional atmospheric environment, it will not easily change color, deteriorate, or fail, and its weather resistance far exceeds that of ordinary organic fluorescent materials. At the same time, the powder is non-toxic, environmentally friendly, non-radioactive, and meets industrial environmental standards. It can be safely used in children’s cultural and creative, decorative coatings, public signage, and other scenarios, and is suitable for the fun and creative use of zinc sulfide powder, fun ideas and the dual needs of industrial production.
3. Excellent physical filling performance
Zinc sulfide powder has a uniform particle size, good dispersion, and strong covering power. As an inorganic filler, it can effectively improve the whiteness, flatness, and weather resistance of coatings, rubber, and plastics. The powder density is moderate, not easy to settle, and has strong processing adaptability. It can be perfectly integrated with various substrates such as resins, solvents, and rubber materials without affecting the physical and chemical properties of the substrate itself. It is a high-quality filler for high-end coatings and rubber modification.
4. Insulation and temperature resistance characteristics
Zinc sulfide powder has good electrical insulation properties, high resistivity, and is not easily conductive, making it suitable for electronic insulation coatings and device packaging materials. At the same time, it has good thermal stability and can withstand conventional industrial processing temperatures. It is not easily decomposed or discolored in high-temperature environments and is suitable for various processing techniques such as spraying, injection molding, and high-temperature curing.
The mainstream preparation process of zinc sulfide powder
The quality differences of zinc sulfide powder for sale on the market are mainly due to differences in preparation processes. At present, the mainstream industrial preparation methods are divided into three categories: wet synthesis, dry sintering, and hydrothermal synthesis. The purity, luminescence effect, and particle size uniformity of the powder produced by different processes vary.
1. Wet chemical synthesis process
Wet synthesis is currently the most mature process for mass production, using zinc salt solution and sulfide solution as raw materials, and obtaining high-purity zinc sulfide powder through precise proportioning, constant temperature reaction, precipitation filtration, washing and drying, crushing and grading. The advantage of this process lies in its high powder purity, low impurities, uniform particle size, high whiteness, and strong stability of the finished product. It is suitable for large-scale industrial production and is also the main preparation method for high-end zinc sulfide powders for coatings and optical materials.
2. Dry high-temperature sintering process
The dry sintering process uses zinc oxide and sulfur powder as raw materials, and the high-temperature closed sintering reaction generates zinc sulfide powder. It is often combined with a trace element doping process to produce luminescent zinc sulfide powder and phosphorescent zinc sulfide powder. The luminescent powder prepared by this process has high crystallinity, good luminescence brightness, and long-lasting afterglow. Its luminescent performance is superior to that of wet powder, and it is the core production process of long-lasting luminescent materials. It is widely used in the production of luminescent labels, luminescent coatings, and handicrafts.
3. Hydrothermal synthesis process
Hydrothermal synthesis belongs to high-end refined preparation technology, which completes crystal growth in a closed high-pressure environment. The resulting powder has a complete crystal structure, controllable particle size, excellent dispersibility, few defects, and stable performance. Mostly used for high-end optical components, precision electronic materials, and high-end luminous cultural and creative products, with higher overall quality but relatively higher production costs, it is mostly used in the high-end customization field.
Industrial application field of zinc sulfide powder
Relying on stable physical and chemical properties and unique luminescent characteristics, zinc sulfide powder is widely used in multiple fields such as industrial manufacturing, decorative, cultural and creative industries, public safety, and electronic optics, covering two major scenarios of industrial production and creative applications.
1. Field of luminous functional materials
Luminous zinc sulfide powder and phosphorescent zinc sulfide powder are the core raw materials of luminescent materials, which can be used to make luminescent coatings, luminescent inks, luminescent plastics, and luminescent decorative products. Widely used in fire safety signs, hallway signs, traffic warning signs and emergency escape markings, it automatically lights up in dark environments, does not require power, is energy-saving and safe and is a must-have material in the field of public safety.
2. Coating and Rubber Modification Field
Ordinary zinc sulfide powder is a high-end white functional filler, which is used in exterior wall coatings, anti-corrosion coatings, rubber and plastic products to improve product whiteness, hiding power, weather resistance and anti-aging ability, replace part of titanium dioxide, reduce production costs, and improve coating flatness and wear resistance.
3. Optics and Electronics Industry Field
Zinc sulfide powder has good transparency and a stable refractive index, and can be used for optical coating, optical lens coating, and fluorescent display materials. At the same time, with excellent insulation properties, it can be used as an insulation coating and packaging filler for electronic devices, improving the stability and service life of electronic equipment.
4. Cultural, Creative, and Decorative Fields
Relying on the advantages of safety, non-toxicity, and beautiful luminescence, zinc sulfide powder has rich and interesting creative uses, which can be used for handmade painting, night light droppings, artistic painting, starry sky jewelry, model making, etc. It is a popular material for DIY cultural and creative, artistic design, and handmade creation, with both ornamental and creative properties.
