Technical characteristics of magnesite slabs , features and application properties

The name of this material is somewhat arbitrary.The fact that the magnesite plate is marketed in the form of sheets a relatively small thickness.Products fairly new, but its technical features and versatility in application is so unique that it is worth a closer look.

What is Plates magnesite (more common abbreviation LSU, indicating that it is the sheet)?In fact, it is an analogue of the well-known to all the drywall, but improved so that in many ways, and can compete with a number of other materials (such as OSB, gypsum fiber board, fiberboard).

But in fact it is one and the same material.This discrepancy is due, probably the fact that LSU produced only in China, but the organization is already involved in the sale, "name-calling" them in his own way, who seem more attractive.

Composition

• Perlite.
• Bishofit.
• magnesium compounds (oxide and chloride).
• wood (sawdust and chips - up to 12%).
• Fillers.

In contrast to the GCR, no plaster.In the course of a chemical reaction of magnesium components forming the crystal lattice, which is the basis of the material.On both sides of the samples reinforced with fiberglass mesh.This specificity determines the structure of the special properties of the PM.

Key Features

1. Dimensions magnesite plate (typical): D - 2.28 or 2.44;W - 1,222 (m).A thickness of up to 3 cm , although the most common patterns that have this option within the 0.3 - 1.2.
2. density - in the range of 1 t / m³ .According to this indicator considerably exceeds the drywall, so often used as a "rough" sex.
3. strength (bending) - this characteristic numerical expression 2.8-fold higher than that of the GCR (up to 26 MPa).
4. Water resistance - within 98% .Experiments confirmed that when in a liquid medium for 4 days the material does not absorb moisture and does not change its geometry.
5. magnesia sheet is not lit (category "NG"), is able to withstand the thermal effect to 1 150 ° C for 2 hours (at a sample thickness of 0.6 cm).
6. Frost resistance - 50 cycles of "frost / defrost".
7. retains heat well and suppresses noise.
8. LSU meets all the requirements of fire safety and the environment (does not contain harmful ingredients).
9. durability.Practice (since the new material) has not yet been confirmed, but experts suggest useful life of several decades.

mounting Features

• Easy cutting sheets, although given the strength of the material, making it more difficult than working with gypsum fiber board, plasterboard or other samples.
• fixation - on the screws (without pre-drilling, for drywall), or applying to a substrate.
• «Finishing» Finishing sheets - any material without limitation.

Scope of magnesite slabs

• Align base.
• Decorating the walls (external and internal).
• «Draft» floor (LSU by 12 mm).
• Multilevel ceiling.
• Interior walls.
• Manufacture of furniture items.
• Ventkoroba channels for laying of communications lines.
• Fixed timbering.
• Shields, banners and so on.

Knowing the characteristics of the product, is not difficult to determine where you can still use the LSU at home.

Experts say only 1 disadvantage of magnesite slabs in comparison with analogues - a high price.It depends on the variety of products and its linear parameters.For example, estimated cost LSU 10 mm 2.5 x 1.22 (meters) - 490 rubles .Although, given all the advantages of the product, as this is essential?
