Shape, a kind of wet-milling dispersant special of demand, and in particular to a kind of system of water-granulated slag wet-milling ethers poly-quaternary ammonium salt system dispersant
Preparation Method.
Background technology
Wet method mechanical lapping is applied to more and more prepares superfine powder, industrial residue discharge process be generally water cooling or
Wet row's mode, water-granulated slag moisture content reach 10%-20%, and wet-discharged coal ash moisture content is higher.Using existing grinding mode need pair
It is dried or burning processing, and fuel (generally light diesel fuel or fire coal need to be consumed to remove wherein moisture water-granulated slag per ton
Powder) up to tens kilograms, more increase the energy consumption of existing processing method.Using Ball-stirring mill wet-milling mode, moisture content in industrial residue without
It must dry, moisture can also play a part of grinding aid in wet-milling, reduce mineral admixture surface energy and intensity.
Wet-milling slurry rheology and wet method mechanical lapping efficiency have direct relation, as powder surface area per unit volume becomes big, slurry stream
Denaturation also reflects the interaction between powder granule and the situation of particle agglomeration.Particle will be produced due to electrostatic force and Van der Waals force
It is raw to reunite or coalesce slurry and then influence rheology.Inorganic, high-molecular type dispersing agent addition in slurry is to electrostatic force and space
Steric hindrance power all has a certain impact, and it, which adsorbs the caused steric hindrance effect on particle, makes to lean on each other between particle
It is too near, so as to slacken intergranular Van der Waals force, for forming slurry stably because adding polymer dielectric.
Wet grinding dispersing agent is the high molecular polymer of low-molecular weight water-soluble mostly, and conventional inorganic dispersant has silicic acid
Sodium, sodium metaphosphate, sodium tripolyphosphate, sodium hydroxide, potassium hydroxide etc., conventional high molecular weight water soluble polymer dispersant have poly-
