泥浆是由水、土及化学药剂组成,这些组分统称之为“泥浆材料”。泥浆工作者习惯把它分成二大类:即“泥浆原材料”及“泥浆处理剂”。前者指的是在组成中所占比例较大的那些添加料,通常指水,土及加重材料。而后者即为加量较小的各种化学添加剂。本文讨论的重点放在后者。 Mud is composed of water, soil and chemicals, these components collectively referred to as “mud material.” Mud workers are used to dividing it into two main groups: “mud raw materials” and “mud treatment agents.” The former refers to the composition of the larger proportion of those additives, usually water, soil and aggravating materials. The latter is a small amount of additional chemical additives. The discussion in this article focuses on the latter.
