合成水煤浆分散剂几种工艺产品的比较

Comparison of Synthetic Dispersant of Coal Water Slurry Several Process Products

以亚硫酸钠、丙酮、甲醛为原料合成磺化丙酮——甲醛缩聚物水煤浆分散剂(SAF)。通过三种不同的工艺流程来合成分散剂,通过实验研究发现,0.6 mol/L,50 mL Na2SO3条件下制得的水煤浆分散剂效果最好,具有良好的分散性能,制浆黏度最低,析水率较低,流动性、稳定性都较好,是理想的水煤浆分散剂。

The dispersant of coal water slurry, sulphonated acetone-formaldehyde polymer（SAF）, is synthesized by sodium sulfite, acetone and formaldehyde. Through the process of three different synthetic dispersants, and the experimental results, 0.6 mol/L, 50 ml Na2SO3 coal water slurry prepared under the condition of dispersant had the best effect, has good dispersion property, pulp and the lowest viscosity, bibulous rate is low, liquidity, stability is good, is the ideal of coal water slurry dispersing agent.
