Find high quality rare high purity microsilica / silica fume wt- 97u grade for refractory with competitive price here. Please rest assured to buy rare high purity microsilica / silica fume wt- 97u grade for refractory with Quanzhou Winitoor Industry Co.,Ltd

  Product Description:                  

Micro-silica fume, also known as silica fume, in the high temperature of 2000 degrees under the oxidation of the formation. Ultrafine high purity amorphous silica, observed under electron microscopy its shape is spherical, amorphous amorphous, the average particle size of 0.2 microns. Has excellent physical and chemical properties.

Micro-silica fume for the improvement of refractory materials have been more than 40 years of history, micro-silica fume for refractory materials will have the following characteristics:

1. To improve the flow of refractory castable, reduce water consumption, making it easy to shape, greatly improve the production efficiency;

2. Due to its ultrafine structure of the interstitial effect, the compactness and strength of refractory material has been greatly improved;

3. Micro-silica fume with high activity, in the presence of Al 2 O 3 composition, the more easy to produce mullite phase, so that refractory high temperature strength, thermal shock significantly improved.

  Features Characteristics:           

1).Appearance is as grey&white off.

2).High electrical resistivity

3).Low Permeability

4).Superior resistance to chemical attack from chlorides,acids and sulfates

5).Low chloride ion diffusion

6).High reactive Pozzolan

7).High temperature strength

8).Improved stability ingeothermal environment 

 Microsilica in application of Refractories                

Traditional refractories in many pores,microsilica fume filling in the pores ,increased bulk density and porosity of lower intensity can significantly enhanced.

Microsilica with strong activity in the water yo form colloidal particles,adding suitable dispersant can be strengthened liquidity, thereby improving performance casting.

Microsilica fume formed easily in the water-Si-oh and has strong hydrophilicity and activity can enhance the coshesion refractories, at the  same time, high temperature performance major improvements, and extens the life of refractory products.

Microsilica fume widely used in the refractory industry following.

Replace aluminum oxide mud for refractories.

As additives production unshaped and amorphous refractory products,its strength,high temperature performance greatly improved.

Shing drums for the overall combination of procoagulant casting agent

Other refractory products cohesion agent, binder, procoagulant agent, additives.

 BENEFITS                        

Prevents reinforcing steel corrosion in concrete, due to its extremely low permeability to chloride-ion intrusion and high electrical resistivity.

· Greater impermeability, barring the ingress of moisture, chemicals and other contaminants

· High early strengths, assuring increased efficiency and greater cost effectiveness in production of prestressed and precast concrete

· High ultimate compressive strengths (8,000-20,000 psi), proportionate to amount of silica fume and the water-to-cementitious ratio

· Substantially greater resistance to corrosion, abrasion and erosion, chemical attack and freeze/thaw damage.
