Brief Introduction

Micro-silica fume (scientific name "silica fume," Microsilica or Silica Fume), in the smelting of ferrosilicon and industrial silicon, silicon through the flue gas emitted by steam oxidation, the specially designed filter collected the amorphous powder like silica (SiO 2). Micro-silica fume average 0.**0.*5 μ m in diameter, the size of several cement average 1.0%. Surface area for the ****7 m 2 / g, with strong surface activity.

Specifications:
*-Densified grave Microslica

*-Bulk Densify : ******0kgs/m3

*-Soi2 *5%**8%

*-LOI 4% Max

*-H2O 2% Max

*-Pozz Activity: **0%

*-Package : **0KGS/***0KGS Per Jumbo bag with moisture proof.

Application in concrete

*-manufacture of high permeability (≥ P*0), waterproof concrete structure for the MTR, tunnels, the basement of high-rise buildings;
*-manufacture marine and chemical concrete, because of its dense high performance, effectively prevent the sulfate and chloride ion permeability of concrete, erosion, avoid being reinforced concrete corrosion, thereby prolonging the life span of concrete;
*-in water, highway, bridge projects, the basic needs not only of concrete indicators, its wear and erosion resistance is very demanding, micro-doped silica fume is necessary;
*-micro-silica fume strong activity, a caustic water properties, applicable to the needs of rapid construction early strength, high strength concrete admixtures; tunnels, subways, large-scale structure in the course of construction Pit Support for the high-strength concrete plus jet ; underwater construction projects used in concrete admixture;

Application in refractories
*-traditional refractories in many pores, micro-silica fume filling in the pores, increased bulk density and porosity of lower intensity can significantly enhanced.
*-micro-silica fume with strong activity in the water to form colloidal particles, adding suitable dispersant can be strengthened liquidity, thereby improving performance casting.
*-micro-silica fume formed easily in the water - Si-OH-and has strong hydrophilicity and activity can enhance the cohesion refractories At the same time, high temperature performance major improvements, and extend the life of refractory products.
Micro-silica 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 agents, additives.

Application in other things
*-rubber industry: rubber-plus a certain amount of silica fume, its extension shrinkage, slitting-resistant and anti-aging of a greatly improved, this rubber also has good dielectric properties, low water absorption capacity.
*-for anti-caking agent: replace or mica particles of diatomite to prevent caking fertilizer raw materials.
*-for pellet binders: micro-silica fume large specific surface area, adsorption strong abroad for the glue pellets made significant effect.
*-water glass industry: instead of quartz ore to produce module for the four water glass.
*-cementing in the oil fields as: Jilin Oilfield, Liaohe Oilfield, such as Karamay Oilfield, large-scale use of micro-silica fume, and made good use of effects.
*-in insulation material, waterproof material, paint, coating, printing and so on industrial applications.
