反应物浓度与反应时间对高强石膏前驱体制备的影响
Influence of Reactant Concentration and Reaction Time on High-Strength Gypsum Precursors Synthesis
摘要
Abstract
High strength gypsum precursors ( Calcium Sulfate Dihydrate , CSD ) was firstly prepared from calcium chloride ( byproduct from ammonia-alkali industry ) and sodium sulfate , then alpha calcium sulfate hemihydrate (α-CSH ) was produced via non-autoclave hydrothermal reaction from CSD .The effects of reactant concentration and reaction time on CSD synthesis are investigated .Results indicate that, when reactants concentration (both CaCl2 and Na2SO4) are (or below) 0.5 mol· L-1 and the reaction time is about 24 h, CSD could be produced and converted to well-developed α-CSH easily .The macro-performance of this kind α-CSH could meet the standard of α30 (JC/T 2038-2010).关键词
