High silica glass fibre blanket

 High silica glass fibre blanket

 Rolled material high silica glass felt МКRR-130 GOST 23619-79. Cotton wool fire-resistant heat-insulated (mullicite-siliceous a fibre) is made fusible in the electric furnace pure oxide    aluminium and silicon with the subsequent formation of a fibre by a method bulge. Cotton wool -effective insulating a material. Mullicite-siliceous the fibre is used as thermo-compensating  and heat-insulated a material; for manufacture of fire-resistant production; for manufacturing products of a complex configuration (brake shoes and others); for a high-temperature filtration of gases.

 Fibres of cotton wool chemically racks to influence of acids and alkalis. Given fire-resistant heat-insulated  the material of racks to heatstroke, has good  electrical insulating properties, is elastic and densely applies on designs. Fibres are steady against influence of temperature in oxidizing and neutral environments. In regenerative heat-insulated environment of property decrease. The material is steady against vibrations and deformation, has good sound insulation.

 Application in the industry:

 Thermal isolation of walls and the arches burning , heating and ring furnaces, transport trolleys, bottom pipes of methodical furnaces, caps  air-heater blast furnaces, flue, chimneys and heat-generator;

 -Filling of temperature and compensatory seams of furnaces, cavities in a laying, condensation of doors, choke, windows, torches and oven trolleys;

 -As initial raw material for manufacturing blocks, plates, a paper, sealing inserts, manufacturing of the crushed fibre, manufacturing of high-temperature filters,heat-insulated  blankets for steam and gas turbines, the carrier of catalysts for gas purification.

 Advantages:

 - Low heat conductivity and insignificant accumulation of heat at low weight of a rolled material;

 -Decrease resource-demanding designs of furnaces and reduction of the specific charge of fuel, labour input at installation;

 High thermal stability, inertness water, water pair and to various mineral oils, liquid nonferrous metals.

 - Mullicite-siliceous felt МКРВ-200 GOST 23619-79-is strong, flexible and elastic fire-resistant  heat-insulated a material. It it is easy , knife and cut out necessary forms, paste to a rigid substrate inorganic glues or are fixed by metal fastenings. Felt make of fibres mullicite-siliceous structure which is made fusible in the electric furnace pure oxide aluminium and silicon with the subsequent formation of a fibre by a method bulge. For giving to a material of durability and elasticity in fibres it is added binding. After heat treatment the material gets durability. Felt fire-resistant heat-insulated МКРВ-200 is issued in standard rolls, strips, tapes, sheets, modular modules, inbroaching  floor-mat and other forms on demand of consumers. Properties МКРВ-200.

 Fibres of felt chemically proof to influence of acids and alkalis. At heats it is necessary to protect from action of the concentrated alkalis, fluoric and phosphoric acids. The material is steady against influence of heats in the oxidizing and neutral environment; in regenerative heat-insulated environment of property decrease. Application in the industry.

 -Heat insulation  in air-heater  blast furnaces, in bell-shaped, heating and thermal furnaces at speed of gases no more than 10 km/s; for heat insulation pipes, profitable adapter, cover and heating wells;

 - As a filler heat-insulated fire-resistant seams, sealants of cracks and cavities in a laying, repair of walls and the arches of various furnaces;

 -As high-temperature filters on clearing gases, carriers of catalysts at gas purification, in furnaces reforming;

 -Thermal isolation in power installations of steam and gas turbines, chimneys, flue and heat-generator.

 -Advantages: Reduction of the charge of fuel and materials consumption the thermal unit (a fire-resistant laying and metal designs);

 - Decrease in labour input of installation and increase of reliability and durability;

 High thermal stability and low heat conductivity;

- It is steady against vibration and deformation, high elasticity of a material;

 High chemical stability and electrophysical properties.
