Microstructures and mechanical properties of sodium

Dec 20, 2020 · The sodium silicate and NaOH used in the experiments was obtained from DiYi Chemical Raw Materials Inc., Taiwan. The primary activator was sodium-silicate solution, the modulus (SiO 2 /Na 2 O molar ratio) of which (2.41) was adjusted to 1by adding solid particles of NaOH. The solution was then sealed and cooled for 24 h prior to use.

CN103818915A - Method for preparing high-transparency

Liquid sodium silicate, also known as waterglass, is produced by melting high purity silica sand along with sodium carbonate at 1100-1200oC. The molten glass is combined with water resulting in a solution that may consist of 24-36 weight % SiO 2 with an SiO 2/Na 2O weight ratio between 1.60 and 3.22. For water treatment applications, the SiO 2/Na

Engineering Chemistry: Lesson 11. Scale and sludge

(2) Lowering of boiler safety : Due to scale formation, over-heating of boiler is to be done in order to maintain a constant supply of steam. The over-heating of the boiler tube makes the boiler material softer and weaker and this causes distortion of boiler tube and makes the boiler unsafe to bear the pressure of the steam, especially in high-pressure boilers.

High ratio silicate foundry sand binders - E. I. Du Pont

Whereas for example a sodium silicate solution of ratio 0.5:1 may have an average silica molecular weight of 60 corresponding to one molecule of SiO 2, sodium silicate solutions of ratio 1, 2, 3.5 and 4.0 are formed to have average molecular weights of about 70, 150, 325 and 400 respectively. This is the reason why as mentioned above high ratio
