I. Product Overview This product is a high-performance deoxidizer-grade silicon dioxide independently developed by Shandong Zhonglian Chemistry Co., Ltd. It is a custom-developed auxiliary material specifically designed for deoxidizers, aiming to solve the core pain points in the deoxidizer industry: "insufficient oxygen adsorption capacity caused by poor pore structure, short service life due to poor moisture resistance, and uneven deoxidation effect due to poor dispersion". Based on precise regulation of nano-scale particle size and pore structure, combined with advanced preparation processes such as sol-gel method and optimized airflow crushing technology, the product not only solves the key problems of traditional silicon dioxide in deoxidizer applications but also possesses excellent oxygen adsorption auxiliary performance, moisture resistance and structural stability. It is widely used in food, medicine, feed, electronics, precision instruments and other fields that require deoxidation and preservation, and is exported to Europe, America, Southeast Asia and the Middle East and other international markets. II. Core Product Advantages 1. Optimized Pore Structure and High Oxygen Adsorption Auxiliary Capacity The product has a reasonable specific surface area (≥400 m²/g) and a controllable pore structure (pore size range 3-60 nm), which can effectively adsorb moisture in the environment while providing a stable carrier for deoxidizing components (such as iron powder, activated carbon), significantly improving the oxygen adsorption efficiency and capacity of the deoxidizer. Its core mechanism lies in the adoption of template method and improved sol-gel process to precisely control the nucleation and growth process of silica crystals, realizing the accurate matching of pore volume and pore size distribution with different deoxidizer systems. This effectively enhances the contact area between deoxidizing components and oxygen, accelerates the deoxidation reaction rate, and ensures the rapid and thorough deoxidation effect. 2. High Purity and Excellent Moisture Resistance Strictly adhering to the high-standard requirements of deoxidizer auxiliary materials, the product has a purity of ≥99% and extremely low impurity content (heavy metal lead ≤0.001%, arsenic ≤0.0003%), fully complying with national food-grade, pharmaceutical-grade standards and international advanced standards. The entire production process adopts inert gas protection and high-purity raw material pretreatment technology, which fundamentally avoids the introduction of impurity ions that may affect the deoxidation effect or cause pollution. It has excellent moisture resistance and environmental stability, can maintain structural integrity in humid environments (relative humidity ≤80%), does not absorb moisture and agglomerate, and effectively ensures the long-term stable operation of the deoxidizer. 3. Excellent Dispersion and Compatibility with Deoxidizing Components Relying on the optimized nano-scale particle size distribution (D50=2-12 μm) and surface modification technology, the product has excellent dispersion performance and can be uniformly mixed with various deoxidizing components (such as iron powder, activated carbon, zeolite, etc.). It can form a stable dispersion system with deoxidizing components, effectively preventing the agglomeration of deoxidizing components during storage and use, ensuring that each deoxidizing component can fully contact with oxygen. It improves the utilization rate of deoxidizing components by more than 35%, and ensures the uniformity and stability of the deoxidation effect in the entire packaging space. 4. Flexible Customization Capability It supports personalized customization services for key parameters such as particle size (2-100 μm), specific surface area (300-900 m²/g) and pore structure (3-100 nm). According to the process characteristics and performance requirements of different deoxidizer application scenarios (such as food packaging, pharmaceutical packaging, electronic component preservation, feed storage), it provides highly adaptable product solutions. For example, for food-grade deoxidizers, it can customize fine-particle-size, high-purity silica to ensure safety and dispersion; for electronic component deoxidizers, it can provide moisture-proof and high-stability products to avoid moisture damage to components. 5. Full-cycle Technical Service Guarantee It provides one-stop technical support covering pre-sales, in-sales and after-sales. Pre-sales can provide customized sample testing and deoxidation performance evaluation services; in-sales, it provides technical guidance on the mixing ratio of deoxidizing components and silica, as well as application process guidance; after-sales, a professional R&D team tracks the application effect, solves technical problems such as deoxidation efficiency attenuation and agglomeration, and optimizes product parameters according to user feedback to ensure the maximum exertion of deoxidizer performance.
