1. A preparation method of a ceramic deflocculant-sodium metasilicate polymer is characterized in that silica sand and sodium carbonate are mixed according to the proportion of 1:

  • 1.75-1.85 (weight ratio), heating the mixed powder in a smelting furnace for 2-3.5 hours at 950-1100 ℃

    to dehydrate and melt the mixed powder, carrying out polymerization reaction, cooling and crushing the generated sodium polymetaphosphate to obtain the finished product of the sodium polymetaphosphate.
