Porcelain granite is made from dry powder mass, which is shaped and durable by treatment at an elevated pressure( of the order of 450 kg / cm²) and temperature( 1,250 ° C).Consider the composition of the original mixture does not make sense, because the producers are supplying to the market several varieties of tiles under the general name of porcelain stoneware. On this basis, there are some differences in the properties and specific technical characteristics of ceramic granite of different manufacturers.
* Given that the product range is quite large, all the numerical values listed below are averaged.
Species of porcelain tiles
- Technical.
- Matt.
- Glazed.
- Satin.
- Structured.
- Polished.
- Rustic and a number of others.
All the differences in tiles - only in the methods and quality of processing faces, which in no way affects the main characteristics, but determines only the specific application of a product. The order of cutting ceramic granite is not different and is the same for any variety.
Properties of porcelain tiles
- Minimal water absorption.
- Increased strength( for bending, percussion).
- Resistant to aggressive environments and temperature extremes.
- Low abrasion of faces.
- Color invariability under the influence of unfavorable factors.
Dimensions of porcelain tiles
- Thickness - from 3 to 30( mm).
- Dimensions: the minimum - 5 x 5, the maximum - 360 x 120( cm).The most "running" - 60 x 60, 45 x 45, 30 x 30( cm).
Characteristics
- Wear resistance( mm³) - less than 185.
- Water absorption( %) - no more than 0,5.
- Strength( bending, N / mm²) - more than 35.
- Frost resistance( cycles) - not less than 150.
Each type of tile is characterized by a number of parameters that are in some ways secondary, especially when using products in the private sector, andAre interested except that experts. For example, deviations in the size( in%) of the nominal, the height of the corrugation and the like. Who are interested in such details, can learn them independently. All data are indicated in the accompanying documentation for the goods.
Price
The price of domestic samples - from 480 rubles / m².Porcelain, produced in Spain, is somewhat more expensive - 180 to 200 rubles for a "square".The highest quality is Italian tiles. It is not sold for less than 1 650 rubles / m².
