Introduction to Chengdu refractory silica fume:

一、 Used in mortar and concrete

Silica fume can be applied to high-rise buildings, seaport terminals, reservoir dams, water conservancy, culvert gates, railways, highways, bridges, subways, tunnels, airport runways, concrete pavement and coal mine roadway bolting and shotcrete reinforcement, which can effectively improve the strength, hardness, compression resistance, impact resistance and wear resistance of mortar and concrete.
二、 Used in material industry

1. Silica fume is used in high-performance low cement refractory castables and prefabricated parts, which can increase the service life to three times that of ordinary castables, increase the fire resistance by about 100 ° C, and significantly improve the high-temperature strength and thermal shock resistance. It has been widely used in coke oven, ironmaking, steelmaking, steel rolling, non-ferrous metals, glass, ceramics and power generation.

2. Large iron ditch and ladle material, breathable brick, coating repair material, etc.

3. Application of self flowing refractory casting material and dry and wet spraying construction.

4. Oxide bonded silicon carbide products (ceramic kiln furniture, flame barrier, etc.).

5. High temperature calcium silicate light heat insulation material, high temperature wear-resistant material and products.

6. Corundum mullite push plate for electric porcelain kiln.

7. Corundum and ceramic products, Cylon Jietai products.

三、 Used for new wall and finishing materials

1. Polymer mortar, insulation mortar and interface agent for wall insulation.


2. Cement based polymer waterproof material.

3. Lightweight aggregate thermal insulation and energy-saving concrete and products.

4. Putty powder processing for internal and external wall construction.

四、 Other uses

1. Silicate brick raw material

2. Production of sodium silicate

3. Silica fume can also be used as reinforcing material for organic platform. Because its composition is similar to that of white carbon black produced by gas phase method. It can be used as filling and reinforcing material in polymer materials such as rubber, resin, coating, paint and unsaturated polyester.

4. Silica fume is used as anti caking agent in chemical fertilizer industry.
