Conclusion Of Water Tube Boiler Agent

2017-9-16 · As water evaporates, liquid silicates become progressively tackier and more viscous. As shown in Table III, PQ's N® sodium silicate, for example, has an initial water content of 62.4% and a viscosity (at 20oC) of 1.8 poises. With a weight loss of 6% by evaporation the viscosity increases to
