Water glass is an aqueous solution of sodium silicate. Coating it on the surface of metal can prevent metal from acid and alkali corrosion. It can also be used to bond wood, ceramics, glass and other materials, and can also be used to make solid dye and mordant. Its main component sodium silicate is a kind of mineral adhesive, which can be used to make soap, fabric fireproof agent and so on. What is water glass? Water glass is generally used to refer to the aqueous solution of sodium silicate. Its main component sodium silicate is a mineral binder. In addition to being used as a binder, it can also be used to make fabric fire retardant, soap, paper filler, silica gel and so on.
Water glass is widely used in our life. As a solution, it is often coated on the metal surface, which can form a 'protective layer' on the metal surface, so that the external acid and alkali are not easy to corrode the metal.
In addition, people often use water glass to bond wood, ceramics, glass, asbestos, plywood and other materials. They also use it to make fixing agents and mordants used in dyeing and embossing textiles.
