1. It can be used as a surface coating for fire doors. Because sodium silicate has a good corrosion resistance and can be fireproof, it can be used as a coating on the surface of fire doors, and sometimes it will increase the hardness of the surface.
2. Used to reinforce the soil structure. After the addition of sodium silicate, the soil will quickly absorb it, and then condensation will occur, but sodium silicate needs to be used in a wet state, and it is injected into the soil in a certain proportion.
3. Bonding gaps. Sodium silicate is a very efficient binder that can be used to bond brick walls, and to squeeze water and sand and sodium silicate into the gaps of the wall in a certain ratio, which can be well adhered.
