The primary use of ceramic fiber products:

1. Industrial furnaces: Lining materials for kiln body and pipeline of tunnel kiln, ceramic kiln, rotary kiln, shuttle kiln, etc.

2. Aerospace and military industry: Fire insulation protection of supersonic aircraft, fire insulation protection of high power engines for armored vehicles, ships, etc.

3. The iron and steel industry: Lining materials for ladle, tundish, electric furnace, heating furnace, annealing furnace, mixing furnace and sintering furnace.

4. The petroleum and chemical industry: Lining materials for cracking furnace, heating furnace and piping system.

5. Electric power industry: Nuclear thermal insulation system, steam turbine, boiler piping system.

6. Household appliances: The fire protection and heat insulation of heater, oven, rice cooker, microwave oven, induction cooker, fireplace and other electrical instruments.

7. Construction industry: The fire protection and heat insulation of various high-temperature and cryogenic engineering.

The main features of ceramic fiber products:

1. High temperature resistance: They can contact the fire source and the highest refractoriness can reach 1350℃;

2. They are convenient to use and easy to cut, install and repair, saving lots of working hours;

3. Long service life: They can be made permanent heat-insulating layer, and they can be used continuously for 5~10 years;

4. Economic energy saving: They can save 10-30% energy compared to conventional insulation materials;

5. Environmentally-friendly and non-toxic: They do not release any toxic substances in the fire and high temperatures;

6. Good chemical stability: It can be long-term tolerance of various radiation and most of the acid-base environment;

7. Good insulation performance: The heat insulation effect compared with the general insulation material can be increased by 2~10 times;

8. Good sound insulation and violation absorption: They are fiber materials and they are advanced sound insulation damping material, so the speed of sound in this material will drop to 1/3 in the air.

Here is our process flow:

Our conventional packaging :

1. We package of plastic protective film, and then we choose the appropriate size of the cartons to pack them up.

2. We can also package according to your other requirements.
