Lignsulphonate Used As Additive of CWS

When used as an additive to coal water slurry (CWS), lignosulphonate has the shortcomings of low concentration and high ignition point. To solve these problems, in this article, sodium lignosulphonate was used as a raw material to find out the optimum process to make additives, such as aminated lignosulphonate condensated sulfonated naphthalene (LCSN), aminated lignosulphonate-polystyrene-acrylic (LPSA) and […]
