Cas No. :69012-64-2
Quantity: 10000Metric Tons Specs:WT-90D Price:180 USD Metric Tons Product Description: Micro silica ,also called silica fume or micro silica, is a byproduct of production silicon metal or ferrosilicon alloys. Silicon metal and alloys are produced in electric furnaces.The raw materials are quartz,coal and woodchips.The smoke that results from furnace operation is collected and sold as silica fume, silica fume consists primarily of amorphous(non-crystalline) silicon dioxide(SiO2),its average granule diameter is 0.15~0.20um,specific surface area is 15000~20000m2/kg,and it has extremely strong surface active. 92% min microsilica powder or granular for concrete92% min microsilica powder or granular for concrete92% min microsilica powder or granular for concrete Winitoor hot sale high performance microsilica use for precast concrete with SGS testing 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 the application of refractories 1）Traditional refractories in many pores,microsilica fume filling in the pores ,increased bulk density and porosity of lower intensity can significantly enhanced. 2）Microsilica with strong activity in the water yo form colloidal particles,adding suitable dispersant can be strengthened liquidity, thereby improving performance casting. 3）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. 4）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. Application area: 1) Concrete or Shotcrete • Increase its density and strength, improve the performance on its durability, impact resistance, corrosion resistance, anti-permeability and frost resistance etc 2) Refractory material & Ceramics material • Greatly improve its density, strength and high temperature performance. 3) Cementitous Repair Products (Mortars & Grouts) • Low permeability, increase resistance from chlorides, acids, nitrates and sulfate etc 4) Oil Well Grouting • Increase durability and compressive strength, decrease permeability, better control of gas leakage 5) Concrete Tile, roofing & wallboard,panels • Lightweight and improve the strength 6) Polymers & rubber product 7) other application, such as waterglass industry, thermal insulation material etc. |
