The characteristics of refractory fiber

1 high temperature resistant.

The highest use temperature up to 1250~2500 degrees. The most commonly used asbestos is 

only 500~550 degrees, 580~830 degrees C and slag wool, aluminum silicate fiber reaches more than 1000 DEG C.

2 conductivity is low.

Refractory fiber under high temperature thermal conductivity is very low, such as 1000 DEG C, thermal conductivity of aluminum silicate fiber only for clay brick lightweight clay brick 20%, 38%.

3 small volume densities.

Generally 0.1~0.2g/cm fand, general clay brick lightweight clay brick for 1/20~1/10, 1/10~1/5. Therefore, the application of industrial furnace refractory fiber instead of refractory brick, the furnace body weight, wall thickness. Such as heating furnace lining is reduced by 80%, the furnace wall thickness of 50%.

4 good chemical stability.

In addition to alkali, fluoride, sulphate, almost not affected by chemical erosion.

5 good thermal shock resistances.

Regardless of the fiber material or product, all brick incomparable good thermal shock resistance.

6 low thermal capacity.

1/72 heat capacity of fiber material only light refractory brick, clay brick 1/42. Refractory lining in the afternoon to do, heat loss is small, fuel saving, fast temperature rise, the intermittent operation furnace was love.

7 soft, easy processing.

Can be made into a variety of products and shape of parts, construction is convenient, the labor intensity is low, the effect is good.
