Liquid glass - what is it? Liquid glass, sodium

Everyone knows what ordinary glass is. It appeared in Egypt about 5000 years ago. And there is still a liquid glass. What it is? No, it's not something weird. This is an aqueous solution that is made from sodium silicate.

Total information

Silicate glue, or liquid glass, is a solution of water and silicate salts. When preparing this composition, the same ingredients are used, which are used for the production of glass products.

There are several manufacturing technologies. More popular is the effect of solutions on materials that contain silica at constant temperatures. The second option is the fusion of water and sand.

As for the application, various construction and finishing works are impossible without this composition. There is no better material for waterproofing than liquid glass. What is it, know for a long time, for these purposes, something better has not yet been created. The use of this adhesive many times increases the service life of buildings.

Silicate glue is made on the basis of sodium, potassium or lithium, although the latter is used very rarely. Potassium is used in many areas, and it has excellent technical characteristics and properties. If we compare this glue and liquid glass with sodium, the first composition has a more friable structure. Stitches made using this glue are not stable.

Both potassium and sodium glues can be used in many areas, but the composition based on potassium is much less common. The thing is that its price is quite high. Therefore, it is often replaced with sodium glues.

Composition

In chemical plants, sulfuric anhydrite, iron and aluminum oxide, a silicate module, sodium and calcium oxide, and silicon dioxide are used to produce this universal agent. Liquid sodium and potassium glasses will have sodium and calcium oxide composition, but in smaller compositions. Thus, glass with sodium has 9% sodium, and calcium - only 0.2%.

Specifications

This glass meets GOST 13078-81. The speed with which this material will dry out depends on how and where it is applied. If the glass is used in its pure form, it will dry up within 10 minutes. As a part of the mixtures, the setting time can take from 2 hours.

The density of the glass is up to 1.45 g / cm ³ . Shelf life - 2 years. Specific gravity - 1,45. To melt the silicate glue, it is necessary to heat it up to 1088 degrees.

Production

The process of manufacturing liquid glass is quite complicated, therefore, the material is produced in chemical plants. First of all quartz is ground to sand, and then mixed with soda, potash, sodium or potassium sulfates.

Then all this is melted into a solid cast ingot. Autoclaves are used for this. After melting, the resulting mass must also be dissolved. The temperatures will be about 170 degrees. This process is quite long and takes about 7 hours.

Application

For a long time in the construction industry we have understood and managed to apply liquid glass. What is it, understandable, but how to apply glue? It is due to the main property, or rather high adhesive capacity, this material has become one of the components for various building mixtures.

Sodium and potassium glass have all the same a different composition, and this determines the area of their use. The latter is resistant to chemical and atmospheric influences. Often this material is used as one of the ingredients for the production of protective paints.

Sodium glass can improve the quality of the glue. The material works fine with minerals. Widely used silicate sodium glue for waterproofing foundations. Also on its basis, antiseptic and fireproof mixtures are prepared. But there are other properties that have a liquid glass.

What is it, only professional builders know. However, there is no better means for producing heat-insulating materials. Constructions with this product can withstand very high temperatures.

This material is almost completely harmless to humans. However, it is necessary to work with it extremely accurately: to all the fault alkali is one of the components. It is best to use gloves when working.

Liquid glass: the price is low, the result is at a height

Not only because of its high characteristics, this product was used in construction. Unlike other similar materials, the cost of glass is very low (200 rubles per 5 kg). Therefore, it is used as one of the components in concrete solutions. It is given at its expense to significantly increase the strength of the structure and moisture resistance. Silicate glue is able to fill as much as possible even the smallest cracks or irregularities.

With all the advantages, there is also a small drawback - a fast rate of solidification. Sometimes it's not too practical. Therefore, more often silicate glue surface is simply impregnated. And if it is then painted or plastered, then liquid glass should not be used.

Not only for construction

This material is popular not only in this industry. Many drivers use liquid glass for cars. Until recently, only wax was among the protective equipment for the bodywork, and today a special ceramic compound or unique nanocoating is very popular.

The ceramic coating with liquid glass provides the body with a mirror gloss, high water and dirt repellent properties, high resistance to sunlight, protection from scratches and chemical attack. You can buy liquid glass - the price is very low.

However, nanokosmetiku on its basis should still be looked for in the sale. Also there are certain difficulties with applying these compounds to the bodywork.

Application technology

The process of car processing is called ceramic polishing. It is the same for all nanopreparations. First of all, the car should be thoroughly cleaned. Then perform the degreasing of the entire surface of the body. For this, choose gentle preparations. Further polishing is carried out with the removal of old residues of polishing pastes and various inclusions. Then remove chips and polish again to shine. Then the liquid glass is applied. What it is, they knew for a long time, but they started to use only a couple of years ago. Apply it from 3 to 10 layers. Then the body is dried for 8 hours. If there are certain skills, you can apply the composition yourself. But to do the same in SRT will cost a high price.

How long does the coating last?

Liquid glass for cars on the application of manufacturers can be kept on the body up to 3 years. However, it is recommended to update it more often. It is better to do this once a year, if the machine is used every day.

How to wash a car?

First time to wash the car is not necessary, after all only there is a formation of a hi-tech protective covering. Manufacturers of these mixtures indicate in the recommendations abstinence from washing for 3 weeks. Then on the body there will be practically no dirt, and it will be enough just to rinse.

Reviews

Nanoceramics for cars really work. All those who tried liquid glass, reviews write only positive.

The coating turns out to be very hard, it can not be scratched even with a nail. Water also does not stay on the body. Wax does not give such an effect.

Construction specialists are also positive about the material. Unique characteristics, reasonable price allow you to perform waterproofing works very quickly.
