Description

technical field [0001] The invention relates to the technical field of dispersants, in particular to a coal water slurry dispersant. Background technique [0002] The existing coal-water slurry dispersant has poor stability, is easy to stratify and settle, and has poor dispersion effect, resulting in waste discharge. Contents of the invention [0003] In order to overcome the shortcomings of existing dispersants, the invention provides a coal water slurry dispersant. [0004] The technical scheme that the present invention solves its technical problem is: a kind of coal-water slurry dispersant, comprises according to parts by weight: [0005] 30-40 parts of industrial naphthalene; [0006] Sulfuric acid, 20-30 parts; [0007] water, 20-40 parts; [0008] Formaldehyde, 10-15 parts; [0009] Lime water, 5-8 parts; [0010] Polyacrylamide, 2-5 parts. [0011] According to another embodiment of the present invention, it further includes that the optimum number of indust...
