Introduction

White carbon black, also known as silica, is a critical industrial material renowned for its exceptional physical and chemical properties. This Hezhen Hydrophilic and Hydrophobic Rubber Binder Tyre Usage White SiO2 Powder exemplifies the versatility of silica, offering a wide range of applications across multiple industries. From enhancing rubber durability to improving coating performance, this product is a cornerstone of modern manufacturing. In this article, we delve into its definition, production methods, technical specifications, and real-world applications, supported by authoritative insights from the National Institute of Standards and Technology (NIST).

Product Overview

SiO2 Powder is a nanoscale, amorphous material with a chemical composition of SiO₂·nH₂O. Its unique structure, characterized by a high surface area and porous nature, makes it an ideal reinforcing agent and additive in various industrial applications. The Hezhen product, with particle sizes ranging from 325 mesh to 10,000 mesh, is engineered to meet the demands of specialized markets such as the rubber, coating, and pharmaceutical industries.

As highlighted by the National Institute of Standards and Technology (NIST), silica's properties are pivotal in ensuring precision in industrial processes. "Silica-based materials are essential for applications requiring high thermal stability and mechanical strength, such as in semiconductor manufacturing and advanced composites," notes NIST's research on nanomaterials (NIST). This aligns with the Hezhen product's role in enhancing material performance across diverse sectors.

Key Features and Properties

Chemical Composition

The Hezhen SiO2 Powder is composed of silicon dioxide (SiO₂) with surface hydroxyl groups (nH₂O). This structure contributes to its hydrophilic and hydrophobic properties, making it suitable for both water-based and oil-based applications. The product's purity ranges from 95% to 99%, ensuring minimal impurities that could compromise performance.

Physical Properties

With an apparent density of 0.128 g/cm³, the powder is lightweight yet highly effective as a filler. Its high melting point (1710°C) and non-conductive nature make it ideal for applications requiring thermal and electrical insulation. The product's amorphous structure also enhances its ability to disperse evenly in matrices, improving overall material integrity.

Chemical Stability

SiO2 is chemically inert under normal conditions, resisting corrosion from acids and alkalis. However, it reacts with hydrofluoric acid, a characteristic that must be considered in specific industrial settings. This stability ensures long-term performance in harsh environments, as noted in NIST's guidelines on material durability (NIST).

Production Methods

The Hezhen product is manufactured using two primary techniques: the precipitation method and the vapor phase method.

• Precipitation Method: Sodium silicate reacts with acids to form a silica colloid, which is then dried and sintered. This method is cost-effective and widely used for industrial-grade production.
• Vapor Phase Method: Silane or siloxane is decomposed at high temperatures to produce nano-sized silica particles. This process yields ultra-pure materials (99% purity) with particle sizes as small as 10–20 nm, ideal for advanced applications.

NIST emphasizes the importance of precise production techniques in achieving consistent material properties, stating, "Controlled synthesis methods are critical for optimizing the performance of nanomaterials in industrial applications" (NIST).

Technical Specifications

Applications Across Industries

The Hezhen SiO2 Powder is a versatile material with applications in over a dozen sectors:

• Rubber Industry: Acts as a reinforcing agent, improving strength, wear resistance, and aging resistance. Over 75% of the product's usage is in this sector.
• Coatings and Inks: Enhances adhesion, hardness, and UV resistance, making it ideal for high-performance coatings and inks.
• Pharmaceuticals: Used to improve drug dispersion and bioavailability, reducing side effects.
• Biomedical: Its biocompatibility allows use in scaffolds, bone replacement materials, and drug carriers.
• Environmental: Functions as an adsorbent for water purification and photocatalytic degradation of pollutants.

NIST highlights the significance of such materials in environmental sustainability: "Silica-based adsorbents are crucial for removing contaminants from water and air, supporting global efforts in pollution control" (NIST).
