Types and properties of porcelain stoneware is a classic example of a combination of high operational and aesthetic characteristics. The popularity of this material is deservedly growing from year to year. When it comes to the flooring of rooms with a high level of attendance, the issue of material resistance to mechanical loads rises acutely. Traditional ceramic tiles and, especially, carpet or linoleum quickly become unusable when used in public and frequently visited residential premises. Relatively young subspecies of tiles will help to solve the problem – ceramic granite. Initially, porcelain tile was used only for gender cladding in technical rooms. The material had excellent characteristics of wear resistance and frost resistance, but did not shine with its appearance. Later, manufacturers achieved significant aesthetically improvements, and ceramic granite found a legal place in the decoration of the most presentable houses and public premises. Types of porcelain tile • homogeneous – has a homogeneous structure (the coloring pigment is not only on the surface of ceramic tiles, but also inside); • glazed – as in tiles, a glaze is applied to the surface, only the composition of the base differs; • partially stained – the tile has the upper pigmented layer and the lower, made in conventional colors; • matte – is not subjected to additional processing and, therefore, is not distinguished by sophistication, but with high strength indicators; • Pierced – porcelain tile with a soft gloss of the surface; • polished – is distinguished by a pleasant sheen, but has restrictions on use as a floor covering; • structured-the surface of the tiles is made in the form of any texture. Properties of porcelain tile • hardness – by this indicator, ceramic granite exceeds natural stone and abrasive materials; • moisture resistance – the level of absorption of moisture in porcelain tile 0.05%, which is an order of magnitude better than the moisture resistance of ceramic tiles and natural finishing materials; • inertia to chemical compounds; • refractory – ceramic granite can serve as an additional protection of building structures in fires; • environmental friendliness – 100% natural material; • stability to abrasion – the main types of porcelain tiles are suitable for use as a floor covering of frequently visited public premises; • Frost resistance – the material is suitable for use at temperatures up to – 50.
