摘要
以丙酮、甲醛、亚硫酸钠为原料 ,合成了磺化丙酮 -甲醛缩聚物型水泥分散剂 ,考察了亚硫酸钠用量、醛酮比等因素对水泥浆分散性能的影响 ,表明当ω(亚硫酸钠 )∶ω(甲醛 )∶ω(丙酮 )为 0 1 6∶0 5 3∶0 2 0时 。
The cement dispersant of sulphonated acetone-formaldehyde polycondensates was synthesized by formaldehyde, acetone and sodium sulfonate. The effect of sodium sulfonate dosage and the proportion of formaldehyde and acetone were studied. The results showed that the best proportion of sodium sulfonate/formaldehyde/acetone was 0 16/0 53/0 20.
