Description

MKRR - 130 - Cotton wool (mullito - silicic fiber) fire - resistant heat - insulating is made by melting in the electric furnace of material of the aluminum containing pure oxides and silicon with the subsequent formation of fiber by method of a razduv.
MKRR - 130, MKRV - 200 - cotton wool effective heat - insulating material.

Mullitokremnezemisty fiber is used as thermocompensation and heat - insulating material in production of fire - resistant production; in production of products of a difficult configuration (brake shoes and others); for a high - temperature filtration of gases.

State standard specifications physical and chemical MKRR - 130 properties 23619 - 79voylok technical,

Fibers of cotton wool are chemically resistant to influence of acids and alkalis. This fire - resistant heat - insulating material is resistant to thermal shock, has good electroinsulating properties, is elastic and densely applies to designs. Fibers are steady against influence of temperature in oxidizing and neutral environments. In the recovery environment heat - insulating properties decrease. Material is steady against vibrations and deformation, has good sound insulation.

Advantages

Mullitokremnezemisty cotton wool (kaolinic cotton wool) - effective heat - insulating material which is used as heat - insulating and thermocompensation material, and also for production of plates, paper, various molded articles, etc. Cotton wool technical met a form of the cloth twisted in a roll. For temperature increase of application chrome oxides can be entered. Fibers are steady against influence of temperature in oxidizing and neutral environments.
In the recovery environment heat - insulating properties decrease. Material is steady against vibrations and deformation, has good sound insulation.

Other advantages:

- low heat conductivity and insignificant accumulation is warm with a low mass of fibrous material;
- resistance to fusions of non - ferrous metals;
- fiber is not moistened with liquid aluminum zinc, magnesium and their alloys;
- resistance to vibrations and deformations;
- resistance to thermal shocks;
- decrease in material capacity of a design;
- the high electroinsulating rates which are a little changing with temperature increase to 700 - 800 °C;
- alkalis resistance (except concentrated), and also to the majority of other chemicals.
- inertness to water, oils.

Application:

Felt technical is intended for thermal insulation of walls and the arches of calcination, heating and ring furnaces, transport trolleys, hearth pipes of methodical furnaces, caps of air heaters of blast furnaces, gas flues, chimneys and heatgenerators;

Filling of temperature and compensation seams of furnaces, cavities in a laying, consolidations of doors, gates, windows, torches and oven trolleys;

Felt construction is used as initial raw materials for production of blocks, plates, paper, sealing inserts, brake shoes, production of the crushed fiber, production of high - temperature filters, heat - insulating blankets for steam and gas turbines, the carrier of catalysts for gas purification.
