Specifications and application of glass adhesive sheet

The modern building market is rapidly evolving, offering the user fundamentally new products. One of the latest new products are glass adhesive sheets (SML, Novolist, Stroylist, Magnezit, GlassAgnezit). The material appeared relatively recently, however, it is already confidently competes with such "veterans" as a plasterboard and a chipboard, surpassing them for a variety of technical characteristics.

In order to better figure out the functionality of the CML, it makes sense to familiarize themselves with the technical characteristics of the material.

Composition and structure of glass turbines

Glass-magny sheet is a monolithic stove of composite materials. The basic composition includes such a proportion of components:

Magnesium (oxide) - 40% .

Sodium (chloride) - 35% .

Wood chips, shallow fraction - 15% .

Glass of volcanic origin - 5% .

Binding components - no more 4% .

Deviation from the indicated rules on 1-2% . It should be noted that for giving the plate of high rigidity, reinforcement with a fiberglass grid is performed.

The technological process includes the following steps:

Dry mixture of listed components is mixed until a homogeneous mass is obtained.

In a separate container, a saline is prepared, which is not less than a day.

The compositions are mixed before receiving a homogeneous consistency, and are sent to molding.

The sheet profiles are rolled with roller, two-layer reinforcement is performed: the grid is placed in front of the back or face.

Drying and trimming of finished products are carried out.

After the final stage, the finished sheets acquire a five-layer structure:

The back side with a rough surface that provides better adhesion with the surface.

Fiberglass mesh.

Layer of filler.

Fiberglass.

Facial profile with a smooth surface that allows you to carry out the finishing finish immediately after installing the plate.

It is worth noting that this is the reference structure that all manufacturers are observed.

The scope of application of a leaf construction and finishing material based on a magnesiac binder

Considering that the material has very good technical specifications, glass adolescent sheets are widely used for internal and exterior decoration, private and multi-storey building. In particular:

Internal partitions.

Door pastes and arches.

Ventilation boxes.

Multi-tier ceilings.

Chimneys.

Finishing the bathrooms and baths.

Unable formwork for filling light concrete.

Floor coverings.

It is worth noting that the sheets have a minimum weight, so installation work can be performed on their own.

Classification. Sl

The glass champions are manufactured by domestic and European manufacturers. In this case, the products are divided into several classes that determine the strength, and accordingly the cost of the product. The material made outside of Russia is marked with the letters of the Latin alphabet, indicating the density of the structure.

It looks like this:

Strength class A. - 1 750 kg / m3.

B. Strength class - 1 500 kg / m3.

Strength C. - 1 250 kg / m3.

Strength class D. - 1 000 kg / m3.

E. strength class - 700 kg / m3.

F. strength class F. - 500 kg / m3.

G. strength class - less than 500 kg / m3.

Russian manufacturers produce three classes products: "Premium", "Standard", "Economy"which are similar to European standards A., B., C / D. respectively.

Products class below domestic enterprises are not available because they contradict the standards GOST For finishing materials.

The advantages and disadvantages of constructionist

Characteristics and properties of glass adolescent sheets make them quite competitive in the Russian and global market. Unlike analogs, the material has such advantages:

Sustainability almost to any external influences without loss of properties.

High elasticity.

Non-hatching: at temperatures up to 1,000 The material is not ignited.

Specific low weight.

Long service life - up to 50 years.

Environmental Safety.

Easy installation and processing: You can use any tool.

Neutrality to pathogenic microflora: wall mold, fungus.

Understanding the low cost of materials, which attracts the attention of buyers to the material.

The disadvantages include:

The ability to bundle material.

Fragile angles, which requires compliance with caution when installing.

Repaired low moisture resistance.

It is necessary to clarify that these technical nuances are characteristic only for Economy class products.

Typical dimensions of glass magnium sheet (CML)

Considering that the material is manufactured by identical technology, manufacturers try to adhere to the same size. Standard Outer Slab Dimensions make up 1 220 * 2 440 mm. The thickness of the CML depends on the scope of application of the material and varies within 3-20 mm.

Enterprises engaged in the production of glass chairs can produce products in the size of the customer, but such products are usually not received in free sale.

Technical characteristics of building material

The glass edge plates are manufactured in strict accordance with the established standards. Therefore, such technical parameters are characteristic of finished products:

Soundproofing - up to 44 dB..

Moisture absorption - 0.34% from the total mass.

Bending resistance - 16-22 MPa Depending on the state of the material (dry / wet).

Heat insulation - 0.14 W / MK.

Frost resistance - 50 cycles.

Fire Safety Class - NG.

It is worth noting that the thickness of the sheet in 6 mmmay resist open flame to one and a half hours.

Subtleties selection of quality products

To buy high-quality building material, specialists are advised to be guided by the following criteria:

Tint. Light gray or completely white panel color indicates the use of amateur raw materials. High-quality sheets have a light yellow or beige shade.

Corners. If the plates geometry is broken and the end and angular surfaces crumble, the manufacturer has been broken by the manufacturing technology.

Backside. Sometimes the rear surface is performed from physiolen (indicated on the package). Products on this basis have a reduced level of fire safety.

If possible, you can immerse a sheet into water for several hours. If the sediment appears in the water - this is a sign of poor-quality products.

Verified manufacturers in Russia

The material appeared on the Russian market relatively recently, however, you can already create a certain opinion about the good faith of manufacturers. When choosing a material, you can pay attention to the products of such companies:

SML-Factory..

Russian enterprise offering quality products at affordable prices. The manufacturer works on Chinese equipment, has a semi-automatic production line and staff of qualified employees. It is worth noting that production capacity allow the manufacture of the CML panels according to the customer's individual sizes.

« Etokon».

The company produces products on its own recipe, which fully complies with the current standards GOST. The company recently launched a new automated production line, supports partnerships with direct suppliers of raw materials, strictly monitors the quality of products.

LTD " Buildingvolution».

This enterprise is at the origins of the production of the CML in the Russian region. By adopting a decision on the development of a new direction, the company's laboratory analyzed the glass chairs manufactured in China (the largest supplier in the global market).

Studies have shown that products have a number of significant drawbacks. Therefore, production was established taking into account the mistakes of Chinese manufacturers. Products manufactured multi-stage control, has certificates of quality of international sample.

The presented enterprises managed to earn customer confidence, manufactured products looks more attractive Chinese analogues in terms of price and quality.
