Product Introduction

Microsilica Silica Fume Micro Silicon Powder.

Micro-silica powder is also called silica fume or agglomerated silica fume. When iron alloy is used to smelt ferrosilicon and industrial silicon (metal silicon), a large amount of highly volatile SiO2 and Si gas is generated in the ore furnace, and the gas is discharged and air. Rapid oxidation and condensation precipitation. It is a by-product of large-scale industrial smelting. The whole process needs to be recycled by dust-removing environmental protection equipment. Because of its low density, it needs to be encrypted with encryption equipment.

In terms of particle size, the silicon micropowder is processed from natural quartz and has a relatively large particle size of 200 mesh, 300 mesh, 400 mesh, 500 mesh, 600 mesh, 800 mesh, 1000 mesh, 1250 mesh, 3000 mesh, 5000 mesh, 10000 mesh, etc. is a powder state. The micro-silica powder has a fineness of less than 1 μm, more than 80%, and an average particle diameter of 0.1-0.3 μm, which is a gray state.

Silicon micropowder and silica fume have mutual substitution, but H-series micropowder performance is superior in concrete and refractory fields: silicon micropowder is added to special refractory materials (such as Portland cement, kiln brick, etc.) to form in oxidation. The multi-layer protective layer has good mechanical properties and high temperature and oxidation resistance. After adding ultrafine silicon micropowder into the special refractory material, its fluidity, sinterability, bonding and filling pore properties are improved to different extents. Increased structural density and strength, reduced material wear rate, and enhanced corrosion resistance.

Product Details

Function and use.

1. Significantly improve pressure resistance, flexural resistance, impermeability, corrosion resistance, impact resistance and wear resistance.

2. It has the functions of retaining water, preventing segregation, bleeding, and greatly reducing the pumping resistance.

3. Significantly extend the service life of the crucible. Especially in harsh environments such as chloride salt pollution, sulfate attack, and high humidity, the durability of tantalum can be doubled or even multiplied.

4. Greatly reduce the falling ash of the spray raft and the castable, and increase the thickness of the single spray layer.

5, is a necessary component of high-strength, has C150 engineering applications.

6. It has the effect of about 5 times of cement. It can be used in common concrete and low cement castables to reduce cost and improve durability.

7. Effectively prevent the occurrence of strontium aggregate reaction.

8. Improve the compactness of the cast refractory. When coexisting with Al2O3, it is easier to form a mullite phase, which has high temperature strength and enhanced thermal shock resistance. 9. It has a strong volcanic ash effect. When mixing concrete, it can react with the cement hydration product Ca(OH)2 to form a gelation product, fill the cement stone structure, improve the microstructure of the slurry, and improve The mechanical properties and durability of the hardened body.

10. Microsilica powder is amorphous spherical particles, which can improve the rheological properties of concrete.

11. The average particle size of the micro-silica powder is relatively small, has a good filling effect, can be filled between the gaps of the cement particles, and improves the strength and durability of the concrete.
