Ceramic cords (keramoshnur)
Ceramic cord - high-temperature (T = 1200C) the sealing and thermoinsulating material applied as fire-resistant isolation and consolidation of oven doors, as consolidation of doors of coke furnaces as sealing and pro-masonry material at the aluminum plants, at the foundry enterprises, on oil processing productions and power plants. in thermal units and heat-conducting systems, furnaces, torches, heat exchangers, sushka. Ceramic cords found broad application also in the household equipment, So for example the ceramic cord is used as consolidations of furnace doors of room wood fireplaces and as fire-resistant isolation in coppers.
Represents an elastic twisted (kanatoobrazny) cord by means of which effective isolation of oven doors (for example, doors of coke furnaces), installations deep a steel vakuumirovniya and so forth is provided.
Process of combustion of fuel in solid propellant coppers is followed by release of smoke, carbon dioxide and very small parts of ashes. At insufficient sealing of a copper products of burning can come to a boiler room, leading to smoke and pollution of the room.
The sealing ceramic reinforced cord helps to reach good sealing of doors of a copper. Usually it is used on door perimeter that at its closing cracks on joints were not formed.
The heat insulator from ceramic fiber has essential advantages before glass and asbestos cords. It are more flexible and maintains big temperature and mechanical loadings. Thus, work of your copper will be more effective and safe, and the term of wear of a cord - is longer, than when using other materials.
The cord is made of dense yarn and braided by thread from the reinforced ceramic material. It is capable to maintain continuous influence of high - to 1100 0C, and low - up to-100 0C temperatures. The cord can transfer not only mechanical loadings, but also contact with aggressive substances, except for fluorine, sulfuric and phosphoric acid. However, in household coppers hit of the listed substances on a cord is excluded.

If to sum up all advantages of a heat-insulating ceramic cord, we receive:
resistance to sharp temperature increase (heatstroke);
stable work at long influence of high temperature;
resistance to naked flame - a cord almost does not burn and does not melt;
nontoxical composition of material;
resistance to influence of the majority of types of acid;
resistance to vibration loadings;
resistance to influence of moisture and solar radiation;
flexibility and elasticity.
