Kremneftorizatsiju (or fljuatirovanie) apply to increase of firmness of external facing and other materials received from karbonatnyh of breeds. At propityvanii limestone chemical reaction occurs a solution fljuata (salts kremneftoristovodorodnoj acids). купить детские книги
The Received insoluble substances in water CaF2, MgF2 and SiCb otlagajutsja in a time also condense an obverse layer of a stone. As a result of it its water absorption decreases and frost resistance increases; facing from a stone becomes soiled a dust less.
Nekarbonatnye preliminary process porous stone materials water solutions kaltsievyh salts (for example, SaS12) and after that impregnate fljuatami.
Stone materials from sandstones process, applying in the beginning a solution of potash soap, and then a solution of acetic alumina. As a result of chemical interaction of these substances in a time and on a stone surface aluminium salt of fat acid, practically not soluble in water is formed.
Gidrofobizatsija, i.e. Impregnation by waterproof structures (for example, kremnijorganicheskimi liquids), lowers penetration of a moisture into a porous stone, in particular, at capillary podsose.
Start to apply to protection of a stone against corrosion film-forming polymeric materials - transparent and painted.
