Characteristics and Uses of Xingyuan Brand Pharmaceutical Grade Zinc Oxide and Feed Grade Zinc Oxide

Characteristics of pharmaceutical-grade zinc oxide: Zinc oxide is a well-known white pigment, commonly known as zinc white. Its advantage is that it does not turn black when encountering H2S gas, because ZnS is also white. When heated, ZnO gradually changes from white and light yellow to lemon yellow, and the yellow color disappears when cooled. Using this characteristic, it can be added to paint or thermometers to make color-changing paint or color-changing thermometers. Uses: Zinc oxide has astringent properties and a certain bactericidal ability. In medicine, it is often made into ointments for use. ZnO can also be used as a catalyst. Characteristics of feed-grade zinc oxide: 1. Compared with other zinc sources, zinc oxide has a significantly lower cost per unit of zinc, which is beneficial for lower

Overview of Nano Zinc Oxide

Zinc oxide nanoparticles are a new type of high-function, high-value-added fine inorganic chemical product for the 21st century. Its particle size is between 1 and 100 nanometers, also known as ultrafine zinc oxide. Due to the miniaturization of the grains, its surface electronic structure and crystal structure change, producing surface effects, volume effects, quantum size effects, and macroscopic tunneling effects, as well as high transparency and high dispersibility, which are not possessed by macroscopic objects. In recent years, it has been found to exhibit many special functions in catalysis, optics, magnetism, and mechanics, making it have important application value in many fields such as ceramics, chemical industry, electronics, optics, biology, and medicine.

Physical properties, uses and characteristics of rubber-grade zinc oxide

Physical properties of rubber-grade zinc oxide: white crystalline system crystals or powder, odorless, non-toxic, fine texture. Relative density 5.606, refractive index 2.008-2.009, melting point 1975. Soluble in acid, sodium hydroxide, ammonium chloride, insoluble in water, ethanol and ammonia, belonging to amphoteric oxide, absorbs carbon dioxide and water in the air to generate zinc carbonate, which is yellow, turns yellow when heated, and recovers white after cooling. It does not transmit ultraviolet light and does not turn black when exposed to hydrogen sulfide. Uses of rubber-grade zinc oxide: In the rubber industry, it is used as a vulcanization activator for natural rubber, synthetic rubber and latex, as well as a reinforcing agent and coloring agent. It can also be used to produce...

Methods for zinc powder preparation

Zinc powder preparation methods: There are two methods: ball milling and atomization. Ball milling produces coarse zinc powder with a wide particle size distribution, but it has high production efficiency, low energy consumption, and low cost. By strengthening the atomization process and screening and grading technology, finer powder that meets the requirements can also be produced. Atomization produces fine zinc powder with high active metal content. 1. Ball milling method Wet ball milling can prepare zinc powder slurry with a flake structure. The flake structure zinc powder has a large covering power, and the amount of zinc powder used when preparing coatings is less than that of granular zinc powder. Atomized zinc powder and fat

The difference in the quality of 99.7% zinc oxide

The difference between indirect and direct zinc oxide lies in their manufacturing materials and processes, resulting in different applications. For tires, indirect zinc oxide is generally used because it is produced from zinc ingots and greatly aids in rubber vulcanization. Direct zinc oxide, however, is produced from zinc ash and has poor rubber vulcanization properties, limiting its use to other applications, typically in ceramics. You get what you pay for. The price of any product is based on cost, and zinc oxide is no exception. Costs are related to raw materials and manufacturing processes. Zinc oxide manufacturing methods are divided into dry and wet methods.

Zinc oxide—Sunscreen in cosmetics

Zinc oxide is used in sunscreens because it acts as a UV ray reflector, using reflection to resist the two main culprits we know: UVA and UVB. UVB has a wavelength of 280-320nm, and UVA has a wavelength of 320-400nm. Zinc oxide can reflect ultraviolet rays with a wavelength of 280-400nm (some data shows it to be 280-390nm). In any case, this wavelength range is quite long. Combined with titanium dioxide (TitaniumDioxide), they can achieve full protection against UVB and UVA. Zinc oxide

Zinc oxide function - latex glove additive

Latex gloves are a type of glove made from latex and zinc oxide. Made from natural latex and other fine auxiliaries, latex gloves undergo special surface treatment, making them comfortable to wear. They are widely used in industrial and agricultural production, medical care, and daily life. Latex gloves made from 100% natural latex have high dexterity, are very comfortable to wear, and have high strength. With a low pinhole rate, they have excellent sealing and protective properties. They are widely used in electronics, food, medicine, and optoelectronics industries. Zinc oxide and natural latex are essential additives for latex gloves, and are also used in

The role of zinc oxide in coatings

The Role of Zinc Oxide in Coatings Zinc oxide is an alkaline compound that reacts with trace amounts of free fatty acids to form zinc soaps, which tend to thicken the paint. It dissolves in inorganic acids or acetic acid. Zinc oxide has a high refractive index and the ability to absorb ultraviolet light. It also has strong coloring power and hiding power, but its color is pure white, it does not chalk, and it has good light and heat resistance. It can form coordination compounds with carboxylate ions in the coating, thereby reducing the sensitivity of the coating to water. Therefore, zinc oxide can improve the weather resistance and anti-chalking ability of the coating, making it suitable for exterior wall coatings. Zinc oxide makes the product coating flexible, firm, waterproof, and ...
