The main raw materials for production of shamotny products is refractory clay. Clays call the sedimentary or destroyed breeds capable to form with water the plastic dough keeping the form given it after drying, and after roasting getting stone hardness. The main material making refractory clay and kaolins is kaolinite (Al203 - Si02 - 2H20) of the following structure: A120z - 46, 6% ; Si02 - 39, 48 of % and H20 - 13, 92 of % .
As raw materials for production of shamotny ogneupor serve clays of the main fields: Chasov - Yarsky and Friends sky (in Donbass), Latnensky (about Voronezh), Borovichi (about Leningrad), Belkinsky, Bogdanovichsky and Buskulsky (in the Urals), Moysky (in Kazakhstan), etc.
Composition of clays of the most large - scale deposit — Chasov - Yarsky following: A1203 + TYu2 — 30 - 35% ; Fe203 — 1, 3 — 3% , fire resistance of 1630 — 1710 °C.
Shamotny refractory clay is the mineral including Si, Al, Mg and also oxides of active metals, compounds of iron and many other things. Contains in shamotny refractory clay for more than 5% of water. the indicator of fire resistance of shamotny refractory clay makes from 1520 to 1850 gr. Celsius (the indicator depends on composition of clay). Refractory shamotny clay is in large quantities applied at construction of various high - temperature constructions (industrial furnaces, chimneys, home furnaces and fireplaces). The most important physical properties of refractory (shamotny) clay are first of all fire resistance, plasticity, temperature shrinkage, granularity. Also in our company it is possible to buy a fire - resistant shamotny mertel of MSh is the mix on the basis of refractory shamotny clay applied to a laying, an obmurovyvaniye and a plastering of fire - resistant bricks (for filling of seams between them ranks of a laying of a brick). Merteli shamotny happen various brands - MSh 28, MSh 31, MSh 36, MSh 39, select brand of a mertel under type of fire - resistant materials with which this shamotny mertel will be applied.
