Asia Chemical provides advanced sodium silicate plant machinery, and the sodium silicate produced meets quality standards. At the same time, Asia Chemical provides follow-up technical services and after-sales services to provide you with the most professional sodium silicate plant machinery engineering services.
Sodium Silicate Description
There are two processes for sodium silicate production. The first one is reaction in liquid phase; the second one is reaction in solid phase. However, alkaline and quartz sand are the same raw materials used in the two processes.
Use of Sodium Silicate
A. Applying the surface of the material to improve its weather resistance. The water glass with a density of 1.35g/cm3 is impregnated or coated with porous materials such as clay brick, cement concrete, Portland concrete, stone, etc., which can improve the compactness of the material. Strength, impermeability, frost resistance and water resistance.
B. Reinforced soil alternately injects water glass and calcium chloride solution into the soil, and the resulting silicic acid gel is in a humid environment, and the soil is in an expanded state due to absorption of soil moisture, thereby consolidating the soil.
C. Formulate quick-setting waterproofing agent.
D. Repair the cracks in the brick wall. After mixing the water glass granules, granulated blast furnace slag powder, sand and sodium fluorosilicate in an appropriate proportion, directly press into the cracks in the brick wall to bond and reinforce.
E, sodium silicate aqueous solution can be used as the outer surface of the fire door.
F. It can be used to make acid-resistant clay for the inner village of the furnace. Physicochemical properties.
G, preparation of silica gel.
Solid Sodium Silicate
Process 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 produced by this thermal process has the modules depending on requirements of different applications.
Application filed: to be widely used in glue making, melting mould casting, mine selection, fast dry cement etc field.
The sodium silicate plant machinery produce solid sodium silicate , with the ratio 1.8-3.6, with block form.
1. Finished product to be solid, convenient for transportation, and low transportation cost.
2. Finished product used in widely range, mole ratio can be regulated during dissolving work, almost applicable for all the industrial work.
