Coal gangue, zircon sand and other raw materials are melted at a high temperature of 2000 degrees, and then made into ceramic fiber loose cotton by spraying or spinning process, and then made into ceramic fiber blanket by double-side needling process. Produced by the spray process, we call it a spray blanket; It is made by spinning silk. We call it spinning silk blanket. What are the differences between a blown carpet and a silk rug? Let’s have a look.

1. Fiber diameter: The spinning fiber is thicker, with a diameter of 3.0-5.0 Micron; The diameter of spinneret fiber is 2.0-3.0 Micron.

2. Fiber length: Longer spinning fiber, 150-250mm in length, and spinneret fiber is generally 100-200mm;

3. Thermal conductivity: due to the thinner fiber of the sprayed silk blanket, the thermal conductivity is lower than that of the dumped silk blanket;

4. Tensile and flexural strength: Because the fiber is thicker, the strength of the cast silk blanket is better than that of the spray blanket;

5. Ceramic fiber module is folded and compressed by ceramic fiber blanket. The quality of the module determines the quality of the furnace lining. Because the fiber is thicker and longer and better than the silk spraying carpet, in the folding process of the block production, the fiber spraying carpet is easy to be broken and torn, and the silk throwing fiber blanket can be folded very closely and not easy to destroy;

6. Ceramic fiber blanket laying-type thermal insulation structure, often used in waste heat boilers and other thermal equipment, should choose durable, strong toughness of the cast silk blanket.
