High Level Metal Silicon Calcium

Silicon Calcium composite polyaluminium chloride iron flocculant and production method thereof. The average composition of the chemical formula of the flocculant is [(AlFe)A#O&(OH)BClC(SiOX)DCaE]n, when n=1, A=1.0, B=3.1-3.5, C=0.20-0.50, D=0.030-0.10, E=0.20-0.40, 2.0≤X≤4.0. The production method is completed by three steps: leaching, polymerization and drying. It is characterized by the addition of sodium silicate as a catalyst and stabilizer to the extractate, and then the alkaline earth metal salt as a polymerizer to the extract for a rapid polymerization reaction. The reaction conditions were room temperature and pressure, pH = 4.0-5.0, and the time was 30-90 minutes. The product is characterized by large molecular structure, fast flocculation speed, and wide range of adaptation to the pH value of raw water.

1.The nanoporous materials prepared by fumed silica and silicon calcium technology are a new generation of nanoporous materials with excellent thermal insulation properties, good mechanical properties and flame blocking properties. The product achieves excellent performance in 1000°C service temperature. By studying the structure, composition and composition design of the matrix, the lowest thermal conductivity of solids during temperature rise can be obtained. Low thermal conductivity of gases as well as limited thermal radiation. Synthetic minerals made from special manufacturing. Calcium silicate powder was used as a stabilizer to improve the inorganic structure of nanoporous material matrices. It has obtained effects such as improved mechanical properties, good processing performance, and low dust, which are more and more accepted and appreciated by more and more users. The latest research work is a double-sided insulation panel with mica foil. The mechanical properties of the product are greatly improved. The product can be used in extremely demanding adiabatic and thermodynamically stable applications. Such as ladle, tundish, electric furnace, etc. and have achieved great success.
