SODA-ASH LIQUID GLASS - POTASSIUM, GOST 13078-81

LIQUID GLASS (SODIUM, POTASSIUM) GOST 13078 - 81

Liquid glass — aqueous caustic solution of Na2O sodium silicates (SiO2) of n and (or) K2O potassium (SiO2) of n. There is a lot of ranges of application of liquid glass. It, in particular, preparations of fireproof paints and coverings on tree apply to production of acidproof cement and concrete, to treatment of fabrics, (fire - retarding agents), strengthenings of weak soil, as glue for pasting of cellulose materials, in production of electrodes, at purification of vegetable and machine oil, etc.

In combination to alcohol and the most fine sand use for creation of "ceramic" or shell forms in which after calcinating to 1000 degrees cast metal products.
Since 2008 several Japanese producers of autopolishes have begun production of polishes on the basis of liquid glass.

Chemical formula: _Na2O(SiO2)n.

SODA - ASH LIQUID GLASS - represents saturated aqueous caustic solution of vitreous sodium silicates. It is gelatinous liquid from colourless till light brown color, the sodium oxide containing in aqueous solution, silicon dioxide, colloid silicon acid and the modified additives.

It is produced by autoclaving of kremnezyomsoderzhashchy raw materials by concentrated solutions of sodium hydroxide or alloyage of quartz sand with soda. Also the ways of receiving liquid glass based on direct dissolution of siliceous raw materials (molding, bergmeals, diatomites, etc. ) in solutions of alkalis are known with atmospheric pressure and rather low temperature (alkali liquor boiling temperature).

The characteristic of chemical composition of liquid glass is silica modul. The module shows the attitude of the silicon oxide which is contained in liquid glass to sodium oxide or to potassium oxide and characterizes silicon dioxide exit in solution. About quality of liquid glass do not judge by the size of silica modul.

Range of application of liquid glass.

Liquid glass has pozharovzryvobezopasny properties. The area of use of liquid glass is very wide.

In construction liquid soda - ash and potassium glass is applied as additives and impregnations.

Mixes on the basis of liquid glass use for production of the hard putties and plasters giving to the elements subjected to processing anticorrosive properties and preserving them against action of high temperatures, and also for waterproofing of overlappings, wells and cellars.

The additive in cement mortars increases their insulating and strength properties. Nonflammable water - glass enamels on the basis of liquid glass use for coloring of rooms with big visit of people, productions of curtains, etc.

Liquid glass is binding substance and is extensively used as all - purpose adhesive for compound of glass, metal of tree and paper. On its basis clerical silicate glue becomes. In the chemical industry liquid glass is irreplaceable by production of silica gel, lead silicate and sodium metasilicate.

Liquid soda - ash and potassium glass is also used in production cleaning and detergents, the soap - producing, textile and paper industry - as binding additives and the gluing structure. In foundry production liquid glass is used as floatation reagent, in ferrous metallurgy in the form of cementing material for production of forms.
