China factory provide amorphous silicon powder

China factory provide amorphous silicon powder  

1. Compression strength.

2. Adhesion strength.

3. Wear resistance. 

4. Freeze resistance.

5. Chemical durability.

6. Considerably reduces permeability.

7. Resistance to Sulfur and Alkali attacks.

8. Increased Insulation Properties. 

It is used best for Insulation properties in Commercial and Residential Infrastructures, such as: Damns, Bridges, Power projects, Transmission Projects, Railways, Canals, Flyovers & Bridges, Highways and Airports, Industrial floorings, Used as admixture for waterproofing, etc.

 It is suggested that even multistory buildings and high end complex’s including heavy infrastructures can use silica fume.

Advantages of Amorphous Silicon Powder in concrete:

Very low permeability to chloride and water intrusion. 

Extremely high electrical resistivity( 20 to 100 times greater  than ordinary Concrete).

Increased abrasion resistance on decks, floors, highways and marine structures, Superior resistance to chemical attack from chlorides nitrates and sulphates. Compressive strengths up to 20000 psi ( 140Mpa ). High flexural strengths(14 Mpa @ 28 days) for airport pavements.

High early strengths for fast track construction projects and precast applications, Highway bridges, parking decks, marine structures and bridge deck overlays are subject to constant deterioration caused by rebar corrosion current, abrasion, chemical attack. 

Silica fume will protect concrete against deicing salts, seawater, road traffic and freeze/thaw cycles. Rebar corrosion activity and concrete deterioration are virtually eliminated, which minimizes maintenance expenses.  

Amorphous Silicon Powder in Refractory
1)The micro silica is as a raw material, commonly used in the refractory industry.
It plays an important role to improve monolithic refractories.
 
2)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.
 
3)Micro silica contains strong activity to form colloidal particles in the water, and adding suitable dispersant to enhance liquidity, thereby improving performance casting.
 
4)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.

Storage and shelf life:
Shelf life when stored in dry warehouse conditions above 2°C is unlimited.

Global supply:

We are specialized in producing and selling silica fume for many years, with customers of Saudi Arabia, Qatar, Kuwait, Japan, Brazil, India, UAE, Finland, Indonesia, Philippines, and so on.
