冷凝硅粉作为活性很高的新型混合材料的研究工作,在国际上已有7～8年的历史,在我国正处于起步阶段仅开展了2～3年.这种材料掺进水泥砂浆和混凝土内,可以改善混凝土的各种性能.因此对开展硅粉的研究,受到有关部门的重视.它既有助于节约能源、提高工程质量、阵低工程成本,并能减少它对大气的污染.冷凝硅粉(简称硅粉),是冶炼硅铁合金的副产品.硅铁合金原料为石英、焦炭、铁矿石在2000℃电弧炉内将氧化硅(石英)还原成硅,排出的废气经静电除尘后收集而成.
Condensation silicon powder as a highly active new mixed materials research work in the international community has been 7 to 8 years of history, in our country is in its infancy only carried out for 2 to 3 years This material is mixed with cement mortar and concrete Therefore, the research on silica fume is valued by relevant departments, which not only helps to save energy, improve the quality of project, lower the project cost, but also reduce its pollution to the atmosphere. Condensation silicon powder (referred to as silicon powder), is a by-product of smelting ferrosilicon alloy.Silicon ferroalloy raw materials for quartz, coke, iron ore in 2000 ℃ arc furnace silicon oxide (quartz) is reduced to silicon, the exhaust gas after electrostatic precipitator Collected
