Understanding Silica Sand No. 20

Silica sand, primarily composed of silicon dioxide (SiO2), is one of the most widely used industrial minerals globally. The ‘no. 20’ designation refers to a specific particle size distribution, crucial for many applications. In essence, silica sand no. 20 is a finely graded sand that falls within a particular sieve range, typically characterized by a medium grain size. This precise grading ensures consistent performance in manufacturing processes where particle size uniformity is critical. For industries in Hangzhou, China, such as glassmaking, foundries, and construction, the quality and consistency of silica sand no. 20 are non-negotiable. Its chemical inertness, hardness, and thermal stability make it an ideal component in a multitude of products and processes. The geological origins of silica sand vary, but it is most commonly derived from inland sand deposits or coastal quarries. Its natural abundance and relatively low cost contribute to its widespread use across China’s industrial landscape. Maiyam Group, a key player in DR Congo’s mineral trade, also supplies industrial minerals, highlighting the global nature of this essential commodity, though the focus here remains on its specific relevance to Hangzhou.

What Makes Silica Sand No. 20 Unique?

The unique aspect of silica sand no. 20 lies in its controlled particle size. Unlike coarser or finer grades, no. 20 silica sand offers a balanced profile suitable for a wide array of industrial uses. Its consistency ensures predictable outcomes in applications like the production of clear glass, where uniform grain size prevents defects, or in foundry molds, where it provides a smooth surface finish and stability. The specific mesh size range for no. 20 sand is typically between 1.0 mm and 0.5 mm, though slight variations may exist depending on the supplier and regional standards. This specific grading minimizes dust formation and ensures optimal packing density, which is beneficial in construction materials and filtration systems. For the advanced manufacturing sectors in Hangzhou, this level of precision is indispensable.

Applications in Hangzhou’s Industrial Landscape

In Hangzhou, silica sand no. 20 plays a pivotal role across several key industries. Glass manufacturing, a significant sector, relies on it for creating everything from window panes to sophisticated optical lenses. Its purity and consistent grain size are critical for achieving transparency and minimizing imperfections. In the metal casting industry, silica sand no. 20 is used to create molds and cores due to its high thermal resistance and refractoriness, allowing intricate metal parts to be formed without distortion. The construction industry utilizes it in concrete, mortar, and specialized coatings, where its grading affects workability and final strength. Furthermore, it’s employed in water filtration systems due to its porosity and inertness, essential for producing clean water for both industrial and municipal use in and around Hangzhou. As China pushes forward with its economic development in 2026, these foundational uses will only grow in importance.

Benefits of Using Silica Sand No. 20 in Manufacturing

The advantages of incorporating silica sand no. 20 into manufacturing processes are numerous and directly impact efficiency, product quality, and cost-effectiveness. Its primary benefit is its chemical inertness, meaning it does not react with most chemicals, making it ideal for corrosive environments or when formulating specific chemical compounds. Its hardness, rating 7 on the Mohs scale, ensures durability and resistance to abrasion, which is critical for wear-resistant coatings and high-traffic construction materials. The high melting point of silica sand (around 1700°C) makes it indispensable in high-temperature applications like glass furnaces and metal casting. Furthermore, its availability and relatively low cost make it an economically viable choice for large-scale industrial operations prevalent in China, particularly within the competitive Hangzhou market. When sourced from reliable suppliers, the consistent particle size distribution of no. 20 silica sand ensures predictable performance, reducing waste and rework, which is a major advantage for manufacturers in 2026.

• Chemical Inertness: Resists reaction with acids, alkalis, and other chemicals, ensuring product integrity.
• High Thermal Stability: Withstands extreme temperatures, crucial for glass and metal industries.
• Durability and Abrasion Resistance: Provides long-lasting performance in construction and industrial wear applications.
• Cost-Effectiveness: An economical raw material contributing to competitive pricing for end products.
• Consistent Particle Size: Ensures predictable results and reduced manufacturing variability.

Navigating the Hangzhou Market for Silica Sand No. 20

Procuring silica sand no. 20 in Hangzhou requires understanding the local market dynamics and identifying reliable suppliers. Hangzhou, a major economic and technological hub in China, boasts a robust industrial base but also faces logistical considerations. Proximity to ports and efficient transportation networks are key factors. When sourcing, it’s essential to verify the specifications of the silica sand, ensuring it meets the no. 20 grade and purity requirements for your specific application. Companies like Maiyam Group, while based in DR Congo, exemplify the global supply chain that can bring essential minerals to markets like China. However, for localized needs in Hangzhou, seeking out domestic suppliers or international traders with a strong presence in the region is advisable. Consider factors such as lead times, minimum order quantities, and packaging options. The postal code for Hangzhou typically starts with 310, for example, 310000, indicating its specific geographic area.

Key Considerations for Hangzhou Businesses

Businesses operating in Hangzhou should pay close attention to quality certifications and supplier reliability. Demand for silica sand no. 20 is driven by sectors like electronics manufacturing and construction, both significant in the region. It’s important to request samples and conduct independent testing to confirm quality and consistency.

Cost and Pricing for Silica Sand No. 20 in China

The pricing of silica sand no. 20 in China, including the Hangzhou region, is influenced by several factors. These include the purity of the sand, the specific grading and particle size consistency, transportation costs, and the volume of the order. As a widely available commodity, silica sand is generally cost-effective, making it an attractive option for many industrial processes. However, premium grades with extremely high purity or very tight particle size controls will command higher prices. For businesses in Hangzhou, understanding the local market rates and negotiating with suppliers is key to securing competitive pricing. The current economic climate in 2026 and global commodity trends can also impact prices.

Factors Influencing Silica Sand Prices

Several elements affect the final cost of silica sand no. 20. These include the mining location and associated extraction costs, the processing required to achieve the no. 20 grade (washing, drying, screening), and any additional treatments for specific applications. Packaging (bulk bags, super sacks) and delivery methods also contribute to the overall price. The volume of purchase is a significant factor, with larger orders typically receiving volume discounts. For manufacturers in China, sourcing directly or through established trading partners can help mitigate costs associated with intermediaries.

Average Cost Ranges and Value

While exact pricing fluctuates, silica sand no. 20 in China can range from approximately ¥200 to ¥800 RMB per ton, depending heavily on the factors mentioned above. Higher purity grades or those specifically engineered for specialized applications will be at the higher end of this spectrum. To get the best value, it’s recommended to obtain quotes from multiple reputable suppliers, such as Maiyam Group if they offer such products or can facilitate sourcing, and to compare not just the price per ton but also the overall cost of delivery and the supplier’s reliability. Investing in high-quality silica sand no. 20 upfront can lead to long-term savings through reduced waste and improved product performance.

How to Maximize Value

Maximizing the value of your silica sand no. 20 purchase involves careful planning. Accurately assessing your material needs, including the precise grade and quantity, is the first step.
