What is sodium liquid glass. Liquid glass. Application in mortars

Liquid glass is a well-known material used in many areas of life, both in everyday life and in industry. It is widely used in construction, metallurgy, the production of paints and varnishes, protective automotive polishes, the manufacture of various adhesives and their derivatives, as well as cosmetics and soaps.

Liquid glass is a water-alkaline solution of potassium silicates, sodium or lithium silicates. Based on the composition, liquid glass is divided into three types: potassium, sodium and lithium. Lithium silicate is used only in industry and its release is limited. Sodium silicate and calcium silicate are in great demand.

Calcium liquid glass due to its properties is often used in the production of paints. Resistance to chemical and weathering makes it indispensable. But it is quite expensive and hard to find on sale. More common soda liquid glass. It is not inferior in its physical and chemical qualities to other types, but is more accessible to the buyer. Therefore, it is its characteristics that are of interest.

What are the properties of sodium liquid glass? Let's consider in order.

Benefits of sodium liquid glass

Waterproofing

In the production of concrete building structures, liquid glass is often used for waterproofing. This provides protection from ground water, aggressive atmospheric influences. Sodium silicate is also used in the construction of water structures: wells, pools, basements for their resistance to moisture.

Anti-corrosion protection

Materials treated with liquid glass are reliably protected from corrosion, since silicate particles have strong anti-corrosion properties. It is often applied to metal surfaces against rust formation.

Antiseptic treatment

Using sodium silicate as an impregnation during construction will not have to face the problems of mold, fungus and dampness.

• Adhesion

Adhesion is a high adhesive power, which makes sodium silicate an indispensable material. The use of liquid glass allows you to glue and connect various Construction Materials and solutions.

fire protection

In the construction of buildings and interior decoration, not only non-combustible materials such as concrete, brick and metal are used, but also fire hazardous (plastic, wood). Therefore, such places are treated with impregnation based on liquid glass. The melting point of this material is more than a thousand degrees, so it has high refractory characteristics.

Strength and durability

Sodium silicate increases the strength of products by forming a protective layer on the surface. Silicate crystals penetrate into the molecular layer of solid materials and thus protect them from rapid destruction. When added to cement mortar increases its strength by 1.5 times.

Environmental friendliness

Sodium silicate has no harmful impurities. Therefore, this material is environmentally friendly for humans, which is also considered undoubted advantage its application.

The use of sodium glass in construction

Padding

There are many options for using liquid glass in everyday life. For example, make a primer for a concrete screed. The applied layer will impregnate the surface and increase its strength. For its preparation, it is necessary to mix silicate and cement in a ratio of 1/1. First mix cement with water and add liquid glass at the end. Stir with a mixer and apply quickly, otherwise the mixture will harden.

Tips:

• The drying time of liquid glass is 10 minutes, in solutions from several hours.
• If the solution solidifies, add a small amount of water and mix with a mixer.
• If laying tiles is planned, dilute sodium silicate with water for a primer.
• If clean liquid glass was used before applying the solutions, do not wait for it to dry completely. A hardened glassy film can interfere with good adhesion of the applied formulations.

waterproofing mortar

When protecting wells and tanks from waterproofing, it is worth trying, because moisture also comes from groundwater, outside the structure. To process such structures, you must first apply liquid glass to the entire surface. Then mix a solution of equal parts sand, cement and soda glass and apply a second coat.

Advice: when using reinforced concrete rings in the construction of the well, carefully process the joints of the rings.

When added to concrete solutions for the purpose of waterproofing, water glass and concrete are mixed 1/10. Such a composition is used in basements, for pouring artificial reservoirs.

Water-resistant flooring can also be made using sodium silicate. We are preparing a cement-sand composition, in which there is 2.5 times more sand. Add a mixture of liquid glass and water, where water is 85% and sodium silicate is 15%.

Puttying voids and cracks in the treated premises is made with a mixture of sand, cement and liquid glass 3/1/1.

Advice: in order to increase the strength and waterproofing properties, it is necessary to refill the outer surface of the floor with sodium silicate.

Outdoor work

Waterproof plaster with the addition of liquid glass is used to protect walls from the damaging effects of atmospheric influences. This is especially important in regions where the northern climate and a lot of rainfall. Everyone knows that the material is gradually destroyed from the inside from frequent thawing and freezing of water. Therefore, it is necessary to treat with waterproofing solutions. At home, for the manufacture of plaster, you need to make a mixture of soda glass, cement and sand 1/2/5 and mix.

When using lime mortars, liquid glass is also added.

Tips:

• The walls can be pre-primed with dilute sodium silicate with water.
• In the case when subsequent painting or plastering of the surface is planned, it is better not to use liquid glass. The surface will be too smooth and the solution will not be taken.
• In masonry work for outer cladding Chimneys from stoves and fireplaces also often contain sodium silicate. It is resistant to high temperatures. The solution is prepared by mixing sand and cement 3/1 and adding 10% water glass.

Impregnation of wooden surfaces

To give wooden materials fire resistance, as well as to protect against mold and fungus, they are treated with a solution of liquid glass. To do this, apply a mixture of sodium silicate and water 1:5 on a pre-sanded surface. Can be applied with paint, spray or roller. If the material being processed is small, you can immerse it directly into the impregnation.

Soda glass is an excellent adhesive composition. It has low consumption and cost. Therefore, you can often meet him in any home. It is used for gluing various things: glass, paper or wood.

Cleaning dishes

Many housewives clean their kitchen appliances with a mixture of sodium silicate. This method is more effective and affordable than cleaning with purchased products. All soot disappears if you prepare a solution of water and liquid glass 25/1 and boil your dishes in it.

Stain removal

Liquid glass is an excellent stain remover. Apply the silicate mixture to the soiled fabric and leave for 10-15 minutes. The stain should be gone.

Helps to remove stains oil paint and varnishes from the surface.

Plumbing work

Many putties water pipes are made on the basis of soda silicate glass.

Car protection

More recently, liquid glass has become in great demand in the care of cars. To do this, the car body is treated with special polishes based on sodium silicate. This will reliably protect the surface from water, dirt and scratches.

Tree processing

Experienced gardeners have long used liquid glass to process cut points near a tree. This disinfects and promotes rapid healing of plants.

• carry out work with gloves and goggles. The product is alkaline, it can leave burns on the skin. In case of accidental contact with eyes and unprotected parts of the body, rinse with water.
• good ventilation in places where liquid glass is stored is necessary
• store in a dark room, away from direct sunlight.
• Freezing and thawing causes a precipitate. At the same time, sodium liquid glass does not lose its properties.
• upon contact with air, the silicate composition quickly hardens, so it is added to the solution just before the start of work and used completely. In some cases, when thickened, it can be diluted with water.
• to increase the service life of surfaces treated with liquid glass, re-work every 3-5 years.

The construction market is represented by a huge number of practical and effective materials that are used in the construction and repair work. One of them is liquid glass, which, due to its unique viscous structure and high performance characteristics used for arranging reliable waterproofing of various types of surfaces.

What is liquid glass? It is an aqueous alkaline product based on sodium and potassium silicates. There is another name for glass - silicate glue. The manufacturing technology of the material provides for the melting of sodium and potassium salts when exposed to high temperatures.

Varieties of liquid glass

Liquid glass was first invented by a German mineralogist at the beginning of the 19th century, since then its original composition has remained virtually unchanged.

Using modern technologies the following types of glass are produced:

• soda glass. Viscous solution based on sodium salts, has increased strength and adhesion with minerals different structure. It is resistant to fire, overheating and deformation.
• Potassium glass. The product, developed on the basis of potassium salts, has a loose structure and high hygroscopicity. Such a surface eliminates the appearance of glare, resistant to overheating and damage.
• Lithium glass. The solution, which is produced in limited quantities, thanks to its structure provides thermal protection to any substrate.

All types of glass are categorized as mono-alkaline products. In addition, there are solutions of a combined and complex type of imported production.

Properties and advantages of the material

Outwardly, liquid glass resembles a viscous rubber mass, which, after hardening, creates a solid waterproof base.

The main properties of liquid glass are distinguished:

Having an idea of ​​​​how to make liquid glass and protective compositions based on it, you can solve issues with waterproofing various types of surfaces.

Product description

Glass liquid sodium - dense liquid; the color may vary from colorless to yellow or brownish. The color depends on the ratio of the content of silicon oxides and sodium. This ratio is called the silicate modulus and is used in some technological processes requiring a specific silicon content in the finished product. From the point of view of chemistry, "liquid glass" is an aqueous alkaline solution of sodium silicate.

Liquid glass is water-soluble, as is its hardened film; has an alkaline reaction; incompatible with most organic substances; forms sparingly soluble silicates with metals.

On an industrial scale, liquid glass is obtained by treating silica-containing raw materials with caustic soda.

Scope of application

Silicate glue is in demand in many areas of the economy. It is used in building mixtures to give them acid and fire resistance. Liquid glass is used as a universal adhesive; cleaning agent; polish; for impregnation of fabrics, paper, cellulose materials; as a raw material for the production of silica gel and some silicates, refractory paints and wood impregnations; for cleaning oils; in the production of electrodes and molds for metal castings; as a reagent for ore dressing and in drilling rigs.

Liquid glass purchased for the manufacture of slip in a ceramic studio proved to be good - products using it are little deformed, high-quality. It's a pleasure to work with him. The product lived up to expectations.

Liquid sodium glass in the catalog of the online store PCGroup at a price of 78 rubles, production. It is possible to buy goods wholesale and retail. The cost and terms of delivery in Moscow and Russia are calculated individually, depending on the region and dimensions of the cargo. Payment is made in cash or by bank transfer.

Waterproofing in construction and garden care in a private courtyard seem to have nothing in common. ...But no! They use both there and there liquid sodium glass. What is this example for? Yes, just the scope of this building material is quite wide and unexpected.

Soda glass composition

Soda glass itself is a hydrous sodium silicate. If it needs to be put into working condition, then sodium silicate is crushed and then dissolved in water. Sodium silicate is also found in nature, but more often it is obtained by chemical means, since it is not difficult and not expensive. In working condition, liquid sodium glass is a viscous liquid gray color or completely colorless. "Viscous" - this is one of its main definitions - in concrete and mortarthis substance is an astringent.

The preparation of mortar or concrete in the future is carried out in the same way as with potash glass. This is because in the chemical formula of both glasses (Na2O(SiO2)n and K2O(SiO)n) only one element differs.

Soda glass properties

It is a good waterproofing agent. Hence biostability: things impregnated with liquid glass are not afraid of rot, mold, fungus, insects. They give strength to building mixtures, as well as mixturesbecome heat-resistant and depend little on atmospheric influence. Liquid sodium glass perfectly glues almost everything, from paper to metal and stone. It can be mixed with water-based dyes and used for interior and exterior painting. Has good penetrating power. Materials with the inclusion of liquid sodium glass resist physical stress well and are resistant to aggressive environments.

Application of liquid sodium glass

The use of liquid glass in everyday life, construction, and in other sectors of the national economy is so diverse ... One listing of this article would not have done, a brochure would have been needed. Therefore, consider its most common use in construction:

1. 1. Production of fire-resistant and acid-resistant masses.
2. 2. Bonding and bonding of building materials.
3. 3. Fixing foundations from groundwater.
4. 4. For adding to materials that need to be fire resistant.
5. 5. To obtain silicate paints.
6. 6. For the arrangement of swimming pools, as well as walls and floors that require waterproofing.
7. 7. For waterproofing industrial tanks, reservoirs and concrete wells.
8. 8. For impregnation wooden products to give them more density.
9. 9. For the repair of previously installed protective waterproofing.
10. 10. For filling voids and cracks.

Obtaining liquid glass and safety measures when working with it

Pure ground quartz sand and soda are thoroughly mixed and sent to the furnace for glass melting. At a temperature of about 1400 ° C, liquid glass is obtained. They release him into the pit. As it cools quickly, the glass cracks and breaks into pieces. The pieces are sent to an autoclave, where they are under pressure up to 8 atm. dissolves steam. The resulting substance is a colloid that has astringent properties. This substance is mineral, and unlike organic adhesives, it does not deteriorate and does not burn. To improve binding properties building mixtures on the 10 l solution is added 1 liter of liquid glass.

As for precautionary measures, their observance has never interfered anywhere. Therefore, when working, wear protective suits and goggles. Well, if liquid glass gets on the skin, then you need to wipe off the drip with a rag, and then wash the place of contamination with soap. If sodium glass gets into the eye, then it should be washed under running water. If it gets into the mouth, it is necessary to rinse it several times, it is not necessary to induce vomiting.

New items appear on the construction market every day: manufacturers improve specifications existing mixtures, paints and heaters, or even develop unique recipes. But some materials are not affected by general modernization - their composition remains unchanged for decades. Among these "mammoths" is liquid glass, which is used in many household and industrial areas.

The inventor of liquid glass (LS) was the German mineralogist Jan Nepomuk von Fuchs, who received the solution in 1818. Alkalis and silicic acid were involved in the chemical process.

The composition of liquid glass has remained virtually unchanged since then. Now it is produced by autoclaving silica-containing raw materials with a concentrated sodium hydroxide solution. The second option is the fusion of soda and quartz sand. In some cases, the method of direct dissolution of silicon in an alkali solution is used (classical method).

Liquid glass is produced in canisters and barrels

The result is two types of material:

• Sodium liquid glass. Differs in high stickiness and adhesion with other minerals, is not afraid of temperature changes and atmospheric influence. Where is liquid glass of this type used? Foundation reinforcement, mold casting, production household chemicals, restoration and repair of glass and porcelain products, refractory processing various materials. It is also suitable for the treatment of damaged shrubs and trees.
• Potassium liquid glass. It has all the characteristics of its sodium counterpart. The only difference is that the composition does not give glare on the treated base, due to which it can be used for outdoor painting work. Included in the composition of refractory and silicate paints, used in the production of electrodes.

The first option is cheaper, but the second one has improved technical characteristics.

Liquid glass properties

Processing with liquid glass performs several functions. The material acts as:

• water repellent - repels water;
• antiseptic - prevents the growth of bacteria;
• antistatic - prevents the formation of static electricity;
• hardener - fills the pores of the treated surface, increasing the density;
• flame retardant - increases the refractory properties, protects against the action of acids.

Liquid glass is an excellent antiseptic

These characteristics determine the advantages of liquid glass:

• Penetrates into the smallest cracks and pores, well covers concrete and wooden bases.
• Creates a waterproof film.
• It has low consumption and low price (compared to other impregnations and water repellents).
• It has a rather long service life (about 5 years). If the waterproofing is covered with a layer of paint, then it will last even longer.
• Allows you to work in high humidity conditions.

The areas of application of liquid glass are limited by the technical characteristics of the composition:

• It is not suitable for waterproofing brick surfaces (due to possible destruction).
• The resulting film is quite fragile, so it is necessary to combine several types of waterproofing.
• The material dries quickly, so professional skills are required to complete the work.

Important! When buying liquid glass, carefully study its composition. The material based on sodium silicates is characterized by high adhesiveness and good adhesion to mineral substances. Potassium liquid glass can be used in acidic environments.

Silicate glue is part of car polishes

Areas of use

ZhS is most often used for waterproofing:

• Basements and attics. The material protects concrete structures from the damaging effects of moisture and gives the surface fire-retardant properties, suitable for indoor and outdoor use.
• Wells. The work is carried out in two stages: first, the walls are treated with a clean composition, the second layer is applied with a solution consisting of a cement-sand mixture and LS.
• pools. Internal processing reduces the likelihood of leaks and destruction of the bowl, external - saves from the harmful effects of groundwater. Materials are applied in a thick layer or in several approaches.

Liquid glass for waterproofing can be used both undiluted and as part of various mixtures, impregnations and additives.

The composition is also used for antiseptic treatment various surfaces. It not only prevents the appearance of mold or fungus, but also destroys the existing "settlements" of harmful microorganisms. Therefore, ZhS is in demand when preparing walls for wallpapering or painting. The solution gives moisture and fire retardant properties to wood, ceramics and paper.

Artistic woodworking

The use of liquid glass in everyday life

What else is liquid glass used for? High gripping ability allows it to be used in the following areas:

• laying linoleum and PVC tiles;
• production of putty for sealing metal pipes;
• impregnation of fabrics to give them fire-fighting properties;
• treatment of wound surfaces on tree trunks (grafting, pruning);
• surface polishing;
• restoration of damaged glass and porcelain;
• production of self-leveling floors in 3D format;
• processing of car bodies;
• art design (decoration of suspended ceilings, ceramic tiles and mirror surfaces, stained-glass windows and mosaic panels).

This is interesting: silicate glue (the second name for liquid glass) has found wide application in creativity - it is used in various types needlework.

How to use liquid glass

In its pure form, the material is used quite rarely; on its basis, they prepare following solutions:

• Primer. Used for surface pretreatment. It is necessary to take equal parts of cement and liquid glass, as well as a sufficient amount of water (the result should be a liquid mixture suitable for application with a roller or brush). First, cement is mixed with water, then liquid glass is added. For cooking, it is recommended to use a construction mixer. The mixture hardens quickly (pot life about 30 minutes), in which case it can be diluted with a little water.
• Waterproofing solution. For waterproofing work, a mixture is prepared from equal parts of sifted sand, Portland cement and silicate glue.
• Refractory mortar. First, a mixture is prepared from 1 part of cement and 3 parts of pure sand, then a small amount of HS is added to it (about 20% of total mass). The composition can be used for laying stoves and fireplaces.
• Antiseptic. To process wood with liquid glass, it is diluted with water in a ratio of 1: 1. The solution is also suitable for stone, plaster and concrete surfaces.
• Strengthening the foundations. To give strength, a solution of 400 g of ZhS and a liter of water is used. Processing is carried out in 2-3 layers, while it is necessary to wait for each layer to dry.

Important! First, all dry ingredients are mixed, after which liquid ingredients are added. The mixture should be mobile and homogeneous. A universal recipe is a liter of liquid glass per 10 kg of the finished mixture.

Instructions for the use of liquid glass

How to apply liquid glass for maximum waterproofing? Observe the following sequence:

• Clean the surface of dust and other contaminants.
• Apply the first coat of primer with a roller or brush.
• Wait half an hour and add another layer. Make sure there are no gaps.
• Prepare a protective mixture of cement, sand and liquid glass.
• Stir the solution and quickly apply it with a spatula to the surface (mind the short pot life).
• Use protective clothing, gloves and goggles during work.

Important! Mix the amount of solution that you can work out in 15-20 minutes. Make sure that foreign impurities do not get into the composition.

Remember to wash your hands thoroughly after work.

Liquid glass for concrete

The use of liquid glass in mortars requires precise proportions. Errors can cause cracks or even collapse of the structure. If you are preparing concrete at home, consider the following nuances:

• On an industrial scale, 72 liters of glue (approximately 7%) are added per cube of concrete mix, which ensures optimal technical characteristics of the finished product. In home production, a ratio of 1:10 is used.
• In no case should silicate glue be added to the finished solution.
• Do not add water to the mixture. First you need to dilute the liquid glass, and then mix the cement powder into the composition.
• Since silicates reduce the setting time of concrete, the mortar must be kneaded in small portions.
• Thoroughly wash your hands and all tools that have come into contact with the liquid after work.

Important! Increasing the dosage of silicate adhesive can lead to complete drying of the concrete.

Do-it-yourself concrete mortar

A solution with liquid glass is prepared as follows:

• Take a bucket drinking water(it is better not to use technical because of the high content of impurities), add a glass of liquid glass to it and mix thoroughly.
• Pour the resulting solution into a large container.
• While continuing to mix the mortar, add the dry concrete mixture in small portions.
• Beat the mixture with a construction mixer until a homogeneous mass is formed.
• Pour the concrete mortar into the prepared formwork.

Important! Prepare the solution in the volume that is necessary for pouring the structure.

The cheapness of liquid glass allows you not to be afraid of fakes. However, when buying silicate glue, pay attention to its consistency. The composition should be uniform, without lumps and inclusions. Do not stock up for future use - the shelf life of the material is 12 months, and you can buy it at any hardware store. Happy building and renovation!
