【摘要】 本文利用廉价易得的石油磺酸盐表面活性剂制备了水煤浆,通过正交实验考察了各因素对同一煤种成浆性能的影响情况,并且通过单因素实验研究了浆体浓度、浆体温度、分散剂PS种类及用量对水煤浆流变性的影响。结果表明:各因素对浆体流变性影响大小为浆体浓度>浆体温度>PS种类>PS用量,而且每一因素对浆体流变性的影响机理也各不相同。更多还原

【Abstract】 This paper prepared coal water slurry using petroleum sulfonate which is very cheap and facile. Through orthogonal experiment this paper studied dispersing performance of CWS using the same coal at different factors and through single factor experiment studied CWS content, temperature, dispersant type and usage affecting rheological properties. Results indicate that factors affecting rheological properties from strong to low are CWS content, temperature, dispersant type and usage, and their mechanisms affecting rheological properties are also different from each other.更多还原
