Advantages of Microsilica's Multi-Field Applications

Micro silica, as a high-performance material with a wide range of applications, has shown great potential in multiple fields due to its fine particles and large specific surface area. Especially in the concrete, refractory materials, lithium-ion batteries, and textile industries, the addition of micro silica not only improves performance but also effectively reduces production cost, enhancing product quality and sustainability.

1. In the Field of Concrete

• Improving Mechanical Properties: The fine particles and large specific surface area of micro silica allow it to fill the gaps between cement particles and participate in secondary hydration reactions with the hydration products of cement, generating gel-like products that fill the cement stone structure, significantly enhancing the compressive, flexural, impact, and wear resistance of concrete. When the addition of micro silica reaches 10%, the compressive strength of the concrete can increase by 6.9%, the tensile strength by 12.8%, and the flexural strength by 11.5%.

• Enhancing Durability: In harsh environments such as chloride contamination, sulfate attack, and high humidity, it can double or even multiply the durability of concrete, effectively preventing alkali-aggregate reactions and extending the service life of concrete.

• Improving Workability: It has water retention properties, preventing segregation and bleeding, significantly reducing the pumping resistance of concrete and greatly decreasing the bounce-back of sprayed concrete and castables, increasing the thickness of single spray layers.

• Reducing Cost: Micro silica has about five times the efficacy of cement, and its application in ordinary concrete and low cement castables can reduce costs.

2. In the Field of Refractory Materials

• Improving Density: It can effectively reduce the amount of water added, has good thixotropy, and can play a role in low-temperature bonding, making it an ideal binder, adhesive, additive, and performance-improving mixture, enhancing the density of castable refractory materials.

• Enhancing High-Temperature Performance: When coexisting with Al₂O₃, it more easily forms mullite, which enhances its high-temperature strength and thermal shock resistance, making it useful in unshaped castables for ladles for high-temperature resistance and molten steel insulation.

3. In the Field of Lithium-ion Batteries

• Cost Advantage: Directly using micro silicon as the anode offers a significant cost advantage and can effectively increase the electrode surface density, simplifying the complex synthesis steps required for nano silicon.

• Reducing Interface Side Reactions: Micro silicon has a relatively smaller specific surface area, which can reduce interface side reactions, crucial for the practical application of silicon anodes in high energy density lithium-ion batteries.

4. In the Textile Field

• Providing Softness and Smoothness to Fabrics: Micro silicon resin belongs to the category of silicone softeners, made from abundantly available silicon in nature. Micro silicon emulsions with particle sizes less than 40 nanometers impart softness, smoothness, and slipperiness to fabrics, giving yarns, knits, plain knits, and woven fabrics made from cotton, polyester, nylon, Lyocell fibers, linen, wool, and their blends a silk-like touch and softness.
