Cement foaming agent, also known as foaming concrete foaming agent, refers to an admixture that can reduce the surface tension of liquid and generate a large amount of uniform and stable foam for the production of foamed concrete. Foaming agent is a kind of substance that can make its aqueous...
The Properties and Main Application Fields of Microsilica
Micro-silica Also known as silica or condensed fume, fume is a form of silica. The mine thermoelectric oven produces many gases, including SiO2 and Si, when ferroalloys (iron alloys) are used to smelt ferrosilicon or industrial silicon. It is formed through rapid oxidation. This by-product is produced during industrial smelting. It is necessary to recycle this entire process with the help of dust removal equipment and environmental protection gear. Encryption equipment is needed because of the low density.
What are the main applications of microsilica?
It is used widely in the refractory industries because it has excellent properties like high refractoriness. It is used for preparing high-temperature ceramics and ladle materials. Wang Tao et al. By using micro-silica and Al2O3 powder in a 3:2.5 ratio and a 1450degC sintering heat, they prepared high-purity mullite porous ceramics. Its compressive strength is 260.93MPa. The porosity of the material is 21%. The micro-silica can improve bulk density, strength, cohesion, and high temperature performance of refractory products. It can also be used to extend the service life and achieve internal digestion of dust produced by ferrosilicon or industrial silicon smelting companies.
The majority of companies in the metalworking industry use microsilica fume to return materials. While this method can reduce environmental pollution due to micro-silica, it doesn't fully exploit the magical properties of micro-silica. This is a very extensive application.
