All about calcium silicate

Calcium silicate is a popular material that is in demand in various fields. Although in its pure form it is a powder substance, from it you can make all sorts of products, for example, refractory plates that are used for facing of fireplaces and stoves. And the material is used in food production and the pharmaceutical industry.

Properties

Calcium silicate refers to the group of inorganic substances. Externally, it looks like white or colorless powder. He has no taste and smell, also the substance does not dissolve in water, and is a good adsorbent – can absorb liquid. It is afraid of exposure to strong acids.

There are various modifications of calcium silicate:

  • orthosilicates;

  • hydrosilicates;

  • Pirosilicates;

  • Metasilicata.

They have certain differences in the chemical formula, although there are always three main components among the main components of the compound: CA, SI, O.

Some of the important characteristics of the material – heat capacity, non-causing and ability to withstand the direct impact of the flame. The refractory insulating plate made from calcium silicate has the following properties:

  • can resist the temperature to 1100 degrees, the time depends on the thickness of the plate, on average such products can hold back the flames from 30 minutes to 2 hours;

  • does not emit toxic smoke, giving the opportunity to evacuate in a fire;

  • Fire-resistant materials are pretty light, which is convenient when installing and working with them, also a small weight does not lose the walls and eliminates the need to install an additional crate;

  • On sheets, mold and other types of fungi are not formed, they will not be interested in rodents, insects and other pests.

The heat insulating plates are used to finish the fireplace and furnace zones in those places where a potential danger is present associated with accidental fire. Material avoids the spread of fire. Products are available with different sizes and thickness, so you can choose the optimal option. Most Popular Parameters: 1080x950x30 mm, 1500x1250x60 mm, 1000x625x40 mm.

Dimensions can be different, it all depends on the manufacturer of the manufacture of sheets.

How to produce?

The substance is obtained by synthesizing the laboratory, and also produced naturally. There is a Mineral Vollastonite, which is a practically pure calcium silicate, with the exception of a small amount of titanium, manganese and iron oxide impurities. In production, the material is synthesized from other natural components: field spat, mica, clay.

Like refractory sheets like this.

  • As ingredients, silica and lime are used to obtain a substance. A chemical reaction occurs between them, as a result of which calcium silicate is formed.

  • In the role of the base for the plate there is a fiber material with high strength. This is a reinforcing carcass.

  • Calcium silicate is applied to the basis and leave for some time to crystallize. During this process, a high-quality seamless cooker is obtained with high fire resistance.

Sheets from this material have a smooth surface, which makes them suitable for any decorative work. It is possible to fasten the products with each other with the help of self-tapping screws, and the joints are easily embarrassed by mastic. Plates without much effort can be cut if it is necessary for mounting.

The most active substance is produced in Denmark and Germany, leaders are SKAMOL and CALSITHERM. In Russia and other countries also have plants engaged in obtaining calcium silicate.

Chinese products are equally popular due to the available cost, but in this case there is a risk to stumble upon low-quality goods.

Scope of application

Depending on the form of the material, there are different ways to use it.

  • Silicate plates are used for cladding fireplaces and furnaces, for finishing boiler rooms, as an additional insulation for better heat insulation. They are suitable for residential and public buildings, as well as technical objects.

  • Powder form of silicate is in demand in the food industry. This additive has an E552 marking. It is used to prevent sticking and competence of various bulk products.

  • Crystals can be part of drugs and biologically active additives, as well as ointments and cosmetics.

  • The substance obtained by synthetic is added to cement, paints, primer and plaster.

  • Silicate is also one of the components in the manufacture of porcelain.

  • In agriculture, the substance is used as fertilizer as a source of silicon necessary for some plants.

Calcium silicate of natural origin is used where it will come into contact with food, cosmetic or medical remedies.

The synthesized substance with additional additives that improve operational characteristics is used in other areas.

Restrictions in use

In many countries, calcium silicate is recognized as a conditionally safe substance. Its use in the food industry is allowed, but in limited quantities and in accordance with sanitary and epidemiological norms. In Russia, it is impossible to use this substance for food production. This is due to the insufficient number of studies necessary to collect the evidence base and determine the safe daytime rate. As for the use of calcium silicate for the manufacture of building materials and other products that are not related to the food or medical sphere, there are no restrictions.
