摘要
表面活性剂对煤表面润湿性的改性处理广泛应用于煤矿防尘、防瓦斯以及煤层气的开采中。利用JC2000C1接触角测量仪测定不同种类、不同浓度及不同复配下煤的接触角和表面张力,研究了表面活性剂对煤润湿性的改性能力。
Surfactant for coal surface wettability modification is widely used in preventing coal dust, gas, and exploitating coal seam gas. The contact angle and surface tension of coal under different kinds, different concentration and different compound were measured by JC2000C1 contact angle measuring instrument. It studied the modification of the surfactant on the wettability of coal.
