Product Description

Polycrystalline Mullite Fiber (PMF) is a novel super-light high-temperature refractory fiber in the world, one of the whole Al2O2siO2 system ceramic fibers, with use temperature of 1800 degrees to 1700 degrees, 200 degrees to 300 degrees higher that that of fiber glass. Polycrystalline mullite fiber (PMF), polycrystalline alumina fiber is currently at home and abroad the latest ultra-lightweight high-temperature fire-resistant fiber, the whole system Al2O3-SiO2 ceramic fibers in two different products, It can be widely used in metallurgy, machinery, electronics, ceramics, chemicals, aerospace and other high-temperature industrial furnaces and other thermal equipment, lined with insulation. In order to achieve energy efficiency increase, extend furnace life, the purpose of improving the working environment. Appearance white, smooth, soft, flexible, just like cotton.

Characteristic:

It is characterized in white appearance, smoothness, softness and elasticity, just like pledget. PMF is a polycrystalline mullite fiber in the existing form of mullite crystalling phase, with a unique structure, complicated manufacturing process and high technical content.

High temperature stability to 1600-1800C
Ideal for use as furnace insulation in sintering, heat treating and chemical thermal process systems
Non-Flammable
Excellent thermal shock resistance
Resistance to most chemical attack; it has excellent stability in acid metal slags and is insoluble in most acids
Resistance to oxidation and attack by furnace atmospheres
Resistance to abrasion
Good electrical resistivity
Excellent thermal stability
Can be used as insulation packing in furnace spaces and around furnace sight tubes & ports
Fill in expansion joints and masonry cracks inside of furnaces.

Note:

1. Data are average results of standard tests which are subject to variation, don't show the guarantee datas of product quality because of fluctuating within certain range.

2. The size is also can be designed according to the clients' requirement.

Advantages:

1. saving the energy

2. increasing the production

3. prolonging the life-span of the stove

4. improving the working atmosphere.

Application:

It is widely applied to the lining insulation of high-temperature industrial kilns and other heat engineering equipment such as metallurgy, machinery, electron, ceramic, chemical, glass, and aerospace.

At present, only few advanced countries are able to produce the product. PMF is extracted by chemical colloid method, and formulated according to crystalling phase---mullite (Al2O3\SiO2). Chemical component is Al2O3-72%,SiO2-28%. Its principle is: the soluble aluminum and silicon salt are made into a colloidal solution, blow the solution and draw the wire by conventional methods, and complete the change of the crystalling phase through high-temperature treatment to obtain mullite fiber. The mullite fiber (loose) wool can be used as the feedstuff of the interlayer of high-temperature position. The loose wool can be made, through wet vacuum mould, into PMF fiber products, such as plate, felt, brick, preformed unit, module and combination part.
