Refractory Fiber Plastic

 

Refractory fiber plastic is an amorphous refractory material, which is made of aluminum silicate fiber, zirconium-containing fiber, alumina powder, filler, dispersant, zirconium oxide sol and plasticizer and other filler chemical binders after being fully mixed and prepared. According to different use temperatures, refractory fiber plastic uses ceramic fiber cotton, powder and additives of different materials to meet different working conditions and design requirements.

 

 

Refractory fiber plastic is made of aluminum silicate ceramic fiber cotton, powder filler, dispersant and chemical binder after being fully mixed. The delivery state is cotton wool and clay. It is an air-hardening material. It can be constructed after opening the bag (barrel). The material is cement-free. After construction, it does not need to be baked in the furnace. After drying, it can be directly heated and operated. It is easy to construct and does not require molds. It is more convenient and quick to transform the old furnace lining. The strength of refractory fiber plastic is greatly improved compared with fiber products. It can withstand high-temperature flue gas erosion under working conditions.

 

1. No cement bonding, using a high-stability binder, gas-hardening materials, less eutectic in the material, self-improvement of refractoriness, good erosion resistance.

2. High temperature resistance, small bulk density, small heat storage, good thermal shock stability, low density, low thermal conductivity, and air flow scouring resistance of 40 m/s.

3. The product can be used directly, without stirring on the construction site, and the construction is convenient.

4. No need for furnace drying and curve heating, the equipment can be directly ignited and operated.

Application area: Refractory fiber plastics are used for thermal insulation and heat preservation construction of kiln linings such as normal temperature pressure reduction furnaces, hydrogen production unit converters, metallurgical industry heating furnaces, and continuous heating furnaces in the petrochemical industry.

Refractory fiber plastics are suitable for radiation rooms, transition sections, convection rooms and other high-temperature parts of some chimneys and elbow boxes (entry holes, fire viewing holes) and for thermal insulation in the bottom of the furnace and the back lining of the furnace wall. Depending on the different products, the use temperature is between 500℃ and 1400℃.
