The result from the study indicates that the washed ore sand from the blast furnace heavy slag can meet the technical requirements of 《Building Sand》 GB/T 14684-2001,and that it has no hidden harm when used in concrete and even produces relatively high strength and relatively better effect to prevent the alkali-aggregate reactio.
研究结果表明,用高炉重矿渣制成的精制矿砂符合GB/T14684—2001《建筑用砂》的技术要求,应用于混凝土中无潜在危害,而且具有较高的强度和较好的预防碱集料反应的作用。
An antirust emulsified oil is formulated by choosing suitable refined mineral oil as base oil and adding proper amount of emulsifier, antirust agent and solubilizer.
选择合适的精制矿物油作为基础油,筛选乳化剂、防锈剂和助溶剂及剂量,研制出一种防锈乳化油,同时确定乳化剂合成的合理工艺,试验表明,研制的防锈乳化油产品质量达到行业指标要求,冷却润滑性优良,易清洗,防锈期长,无毒无味稳定性好。
