Product Description:
Sodium silicate, commonly known as paucine, is a water-soluble silicate, and its aqueous solution is commonly known as water glass, which is a mineral binder. Its chemical formula is R2O·nSiO2, where R2O is the alkali metal oxide, and n is the ratio of the mole number of silicon dioxide to the alkali metal oxide, which is called the mole number of water glass. Water glass commonly used in construction is an aqueous solution of sodium silicate (Na2O·nSiO2).
The proportion of silica sand and alkali, that is, the molar ratio of SiO2 and Na2O, determines the modulus n of sodium silicate, the modulus shows the composition of sodium silicate, and the modulus is an important parameter of sodium silicate, generally between 1.5 and 3.5. The greater the modulus, the more difficult it is to dissolve solid sodium silicate in water, n is 1 often warm water can be dissolved, n is increased by hot water to dissolve, n is greater than 3 requires more than 4 atmospheres of steam to dissolve. The greater the modulus of sodium silicate, the more the content of silicon oxide, the higher the viscosity of sodium silicate, the easier to decompose and harden, and the greater the bonding force, so the sodium silicate with different modulus has different uses.
