HeadPowder, a leading enterprise in the field of powder engineering, specializes in the production and application of high-quality zinc oxide. This article provides a detailed overview of the technical parameters of zinc oxide and the corresponding conveying system processes, aiming to offer valuable insights for industry professionals and potential clients.

Company Profile

HeadPowder, with its full name as Shandong HeadPowder Engineering Co., Ltd., is headquartered in Shandong, China. The company has been committed to the research, development, and manufacturing of advanced powder processing technologies, particularly in the area of zinc oxide production and related systems. Our expertise lies in optimizing material properties and ensuring efficient material handling through sophisticated conveying systems.

Technical Parameters of Zinc Oxide

Zinc oxide (ZnO) is a widely used inorganic compound with a chemical formula of ZnO. It is known for its high purity, excellent thermal stability, and versatile applications in various industries such as rubber, plastics, pharmaceuticals, and cosmetics. The technical parameters of zinc oxide are crucial for determining its suitability in different applications. Key parameters include:

• Chemical Purity: Typically ranging from 99.9% to 99.99%, with minimal impurities like lead, cadmium, or other heavy metals.
• Particle Size Distribution: The particle size can vary from sub-micron to several microns, affecting the dispersion and performance in end products. Common specifications include D50 (median particle size) and span (coefficient of variation).
• Surface Area: A higher surface area indicates better reactivity and dispersion, often measured in square meters per gram (m²/g).
• Moisture Content: Low moisture content is essential to prevent caking and ensure consistent performance. Typical moisture levels are below 0.1%.
• Bulk Density: The bulk density affects storage and handling, with values typically in the range of 0.8 to 1.2 g/cm³.

Conveying System Process for Zinc Oxide

The efficient transportation of zinc oxide from production to end-use applications is critical for maintaining product quality and operational efficiency. HeadPowder has developed advanced conveying systems tailored to the unique properties of zinc oxide. The process typically involves the following steps:

1. Storage and Feeding: Zinc oxide is stored in bulk containers or silos. A feeding system, such as a rotary valve or a screw feeder, controls the flow rate to the conveying equipment.
2. Conveying Methods: For zinc oxide, pneumatic conveying is commonly used due to its ability to handle fine powders without clogging. The system may include positive or negative pressure systems, with positive pressure being more suitable for long-distance transport. The pipeline design considers factors like particle size, moisture content, and flow rate to prevent blockages.
3. Material Handling and Dosing: After conveying, the zinc oxide is transferred to processing equipment or storage tanks. Dosing systems, such as gravimetric feeders, ensure precise and consistent addition of the material to production lines.
4. Control and Monitoring: Advanced control systems monitor parameters like pressure, flow rate, and temperature to maintain optimal operation. Real-time data collection helps in process optimization and quality control.

Quality Assurance and Application

HeadPowder adheres to stringent quality control measures throughout the production and conveying process. From raw material selection to final product delivery, every step is monitored to ensure compliance with industry standards and customer specifications. The technical parameters and conveying systems are designed to meet the diverse needs of clients, supporting the performance and reliability of zinc oxide in their respective applications.
