Sodium Silicate (Water Glass) Equipment

  • Description
Product Detail

 Sodium Silicate Process with reaction in liquid phase:

Caustic soda, quartz sand and water are mixed in a mixing tank, and then the mixture is fed into a reactor, where steam is introduced. 

The reactant is liquid water glass with its module lower than 3. 

The reaction is as following: 


nSiO2+2NaOH  ?    Na2O·nSiO2+H2O  

2.  Sodium Silicate Process with reaction in solid phase (thermal process)

The feed materials in this process are sodium carbonate and quartz sand, or sodium sulfate and quartz sand. The feed materials are heated in a reflection furnace. The reaction is as following:

 

Na2CO3 +XSiO2  ?  (Na2O)•(SiO2)X + CO2

4Na2SO4 +2C +4SiO2 ? 4Na2SiO3 +4SO2 +2CO2

 

The Sodium Silicate (Water Glass) Equipment produced by this thermal process can have modules depending on requirements for different applications.
