Water glass (sodium silicate or potassium silicate), a saturated aqueous solution of glassy sodium alkaline silicate. It is jelly like liquid from colorless to pale brown in the aqueous solution comprising sodium oxide, silicon dioxide, colloidal silicic acid, and modified additives.
Chemical formula: Na 2 O (SiO 2 ) n .
Manufactured by autoclaving raw kremnezёmsoderzhaschego concentrated sodium hydroxide solutions or by melting quartz sand with soda. Also known are methods for preparing water glass, based on the direct dissolution of siliceous raw material (flasks, tripoli, diatomaceous earths, etc. ) In alkaline solutions at atmospheric pressure and relatively low temperature (the boiling point of the alkaline solution).
Liquid glass is Fire - fighting properties. Field of use of water glass is very broad.
In the construction of liquid sodium and potassium is used as glass additives and impregnants. Mixtures based on liquid glass is used for the production of fillers and plasters, which give subjected to processing elements of anti - corrosion properties and protect them from the effects of high temperatures, as well as for waterproofing floors, wells and basements. Additive in cement slurries increases their strength and insulating properties. Non - combustible silicate paints based on liquid glass is used to color spaces with more people visit, the production of theater curtains and so on. N.
Liquid glass is a binder and is widely used as a universal adhesive for bonding glass, metal, wood and paper. It is on this basis is a silicate glue office. In the chemical industry, water glass is indispensable in the production of silica, lead silicate and sodium metasilicate.
Liquid sodium and potassium glass is also used in the production of detergents and cleaning agents, soap, textile and paper industries - as bonding and adhesive additives. The foundry water glass is used as a flotation agent in the steel industry as a binder for the production of forms.
