Embodiment 1
[0012] Embodiment 1, produce the special water glass 3.3M of petrochemical catalyst, Be ' 32 °.
[0013] 1. Use refined quartz sand and sodium hydroxide, Fe<0.02% as raw materials, produce 2.8M, Be'45° sodium silicate solution by wet method according to known technology, and filter it through a plate and frame filter press at 80-100°C for standby .
[0014] 2. Use 2.8M sodium silicate solution to prepare hydrated silicic acid A and prepare silica sol. Take 1.5 tons of hydrochloric acid in the silica sol reaction kettle and dilute to Be'8°. Under stirring, slowly add Be'10° silicic acid Sodium solution, control the pH below 3.5 to prevent the generation of jelly. B. Add an appropriate amount of water into the hydrated silicic acid precipitation kettle and heat it to 80-100°C. Add the silica sol solution and sodium silicate solution under stirring. Control PH < 7 and white hydrated silicic acid will be precipitated at this time. After the slurry is acidified and aged, polyethy...
Embodiment 2
[0017] Production of 3.3M, Be'38° sodium silicate solution
[0018] 1. Use refined quartz sand and sodium hydroxide, Fe<0.02% as raw materials, produce 2.6M by wet method according to known technology, Be'45° sodium silicate solution is filtered through filter press at 80-100°C to become clear and transparent Sodium silicate solution for use.
[0019] 2. Use 2.6M, Be'45° sodium silicate solution to prepare hydrated silicic acid A and silica sol, take 1.5 tons of hydrochloric acid in the silica sol reaction kettle and dilute to Be'18°, and slowly add Be'10 under stirring ° sodium silicate solution, control the pH below 3.5 to prevent the generation of jelly. B. Add an appropriate amount of water into the hydrated silicic acid precipitation kettle and heat it to 80-100°C. Add the silica sol solution and sodium silicate solution under stirring, and control the pH<7. At this time, white hydrated silicic acid will precipitate and the slurry will After acidification and aging, pol...
