What are the practical uses of sodium silicate?
2022-11-28
Sodium silicate can be used in the production and construction of various types of waterproof sealant or fire safety equipment.Thus for our specific application has produced a lot of practical value.So what is the specific role of sodium silicate?Let's take a look at.
1.The brush applied to the surface of raw materials can enhance its weathering resistance
Brush coated or preimpregnated raw materials,the sodium silicate solution will penetrate into the gaps and crevices,when dry, it can block the pore safe passage of the raw material,to increase its hardness and compressive strength,thus giving the data the ability to work against weathering.
2.Structural reinforcement of the soil layer
In roadbeds made of gravel, sand and backfill,the sodium silicate aqueous solution and calcium chloride solution were introduced alternately in the way of two-component grouting.The two solutions quickly react into silicone rubber and calcium sulfate gum,thus, it has the function of bonding and filling porosity, thus improving the hardness and bearing capacity of the soil layer.
3.Equipped with quick-setting waterproof coating
When sodium silicate is configured with a variety of alum,with the actual effect of rapid solidification.It is often associated with copper sulfate pentahydrate arsenic trioxide aluminous or Chromium potassium sulfate is prepared into a variety of quick-setting waterproof coatings for a variety of leak-filling.However, it is necessary to pay attention to the use of the application.
