Micro silica  in Refractory

The microsilica is as a raw material, commonly used in the refractory industry. It plays an important role to improve monolithic refractories.

Microsilica is filled in those gaps of which in the traditional refractories. Thus, it increases the bulk density and lowers the porosity, so that intensity can be increased abviously.

Microsilica contains strong activity to form colloidal particles in the water, and adding suitable dispersant to enhance liquidity, thereby improving performance casting.

Microsilica is easy to form -Si-OH in the water and has strong hydrophilicity and activity. It can enhance the cohesion of refractories, in the meantime, it also improves greatly the high temperature properties and extends the life of refractory products.

Micro-silica fume in the building materials industry and sales

Micro-silica fume is at home and abroad in the field of high and new technology has broad application prospects for the fine material can be widely used in chemical industry, metallurgical industry. For cement or concrete to improve the performance of concrete or cement, prepared with ultra-high, strong, wear-resistant, resistant to erosion, corrosion-resistant, anti-penetration, antifreeze, the early strength of concrete or special cement compound to meet the oil - Well, marine oil drilling platform, harbor terminals, railway bridges highways, airport runways, tunnels and urban high-rise building projects, such as the special requirements; rubber can be used to improve the extension of rubber, tear and tensile strength ; For ceramics and refractories, effective products to improve the strength and durability.
