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.
Process Features:
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.
If you're satisfied with our solid sodium silicate plant, welcome to wholesale the high quality products with competitive price from us. As one of the leading manufacturers and suppliers in this profession, we can assure you of its reliable performance.
Sodium Silicate Plant Machinery
In order to simplify the production process of sodium silicate plant machinery and further improve the production efficiency of sodium silicate, we have been improving the process of producing sodium silicate by the sodium silicate plant machine, in order to allow customers to have the least investment. Produce the most efficient production efficiency. Get the maximum return. And can further reduce investment cost and use cost. In recent years, we have introduced coal-heated production equipment for small and medium-sized customers. And there is a complete set of perfect production process. Can produce any specifications of Paohua alkali.
The biggest feature of our equipment is that it has abandoned the way of using steam for heating in the past. It is heated by direct combustion of coal. The thermal efficiency can be utilized to the greatest extent, and higher temperature and stronger pressure can be obtained, which further shortens the time of dissolution reaction. And save a lot of investment costs.
Q: Is this production method safe?
A: Our equipment is designed with very high pressure. Design pressure is 16 kg. Only 6 kg of pressure is required for normal production. As long as we master the heating time and the amount of coal used for heating, we can control the pressure within a safe range. As a simple example, we usually produce about 200 kilograms of low-calorie coal at a time. 200kg of coal is used for each production, so that the pressure must be kept within a safe range. So it is very safe. This production process has been used for more than ten years, and the experience and technology are very mature.
