摘　　要：论文研究了中国矿业大学(北京)研制的萘系分散剂KY33与两种不同变质程度煤的制浆效果以及添加木质素磺酸钠对水煤浆的稳定性的影响。通过制浆试验,合理选择配比进行制浆,确定KY33的最佳用药量,并通过添加木质素磺酸钠来提高水煤浆的稳定性。利用Turbiscan Lab稳定性分析仪对复配药剂制备的水煤浆的稳定性进行评价。结果表明:不同变质程度的煤对应的KY33最佳用药量不同,但添加适量木质素磺酸钠均可有效的提高浆体的稳定性。The paper studied the coal water slurry property prepared with coals of two different ranks, using KY33（ naphthalene series） as dispersant,and researched the stability variation adding a small amount of sodium lignosulfonate.According to the slurry preparation experiment,with reasonable proportion of coal sample,the optimal dose of KY33 was determined,and the stability of CWS was improved with sodium lignosulfonate. The stability of CWS was evalvated using Turbiscan Lab stability analyzer. The results show that the optimal dose of KY33 varied with the coal ranks,the effect of KY33 and the slurry stability can be effectively improved with a moderate amount of sodium lignosulfonate.
