摘要
以七水亚硫酸钠、无水亚硫酸钠、亚硫酸氢钠、焦亚硫酸钠4种无机盐为磺化剂,采用无热源工艺合成了脂肪族高效减水剂,并以单因素方法研究了4种无机盐磺化剂对脂肪族高效减水剂性能的影响。结果表明,以七水亚硫酸钠为磺化剂合成的脂肪族高效减水剂具有较优的水泥净浆分散性和分散保持性。
Based on sulfonating agent of sodium sulfite with seven crystal water, sodium sulfite,sodium bisulfite and sodium metabisulfite,selfheating productive technology was adopted to synthetize sulfonated acetone-formaldehyde superplastieizer and the method of single factor assessment was applied to study impact of the four kinds of sulfonating agent on the sulfonated acetone- formaldehyde superplastieizer. With the test results,the sulfonated acetone-formaldehyde synthetized by sodium sulfite with seven crystal water performs the better property on cement paste dispersibility and fluidity loss.
